The present invention relates to human monoclonal antibodies and antigen-binding portions thereof that bind to the extracellular domain (ECD) of activin-1 receptor-like kinase (ALK-1). The invention also relates to nucleic acid molecules encoding such antibodies and antigen binding portions, methods for making human anti-ALK-1 antibodies and antigen binding portions, compositions comprising these antibodies and antigen binding portions, and methods of using these antibodies, antigen binding portions and compositions.
Background of the Invention [0002] ALK-1 is a type I surface receptor for transforming growth type beta 1 (TGF-beta-1). Human ALK-1 is a 503 amino acid polypeptide that contains a signal sequence (amino acids: 1-21), the N-terminal extracellular ligand binding domain of TGF-beta-1 or ECD (amino acids: 22-118), the single transmembrane domain (amino acids: 119 -141), the glycine / serine (GS) rich regulatory domain (amino acids 142-202) and the C-terminal serine-threonine kinase domain (202-492). The human ALK-1 amino acid sequence disclosed in Attisano et al. Cell, 1993, volume 75, p. 671-680 contains Ser at position 172 (Genbank register L17075), while US 6316217 claims the amino acid sequence of human ALK-1 with Thr at position 172 (Genbank register NM_000020). The ACVRL1 gene encoding full-length human ALK-1 disclosed in Attisano et al. is commercially available from Invitrogen Inc., Clone ID IOH21048. Although ALK-1 has 60-80% general homology with other type I receptors (ALK-2 to ALK-7), ECD ALK-1 is significantly different from ECD of other ALK family kinases. For example, in humans, only ECD ALK-2 is significantly associated with ECD ALK-1 (exhibits approximately 25% amino acid identity). U.S. Patent No. 6,318,217; this Dijke et al.

[0003] Typically, ligands from the TGF-beta superfamily show their biological activity by binding to heteromeric receptor complexes consisting of two types (I and II) of serine / threonine kinases. Type II receptors are constitutively active kinases that phosphorylate the type I receptor upon ligand binding. In turn, activated type I kinases phosphorylate downstream molecules that signal to the cell nucleus, including various Smad proteins that translocate to the nucleus and lead to a transcriptional response. Heldin et al. Nature, 1997, volume 390, pp. 465-471. In the case of ALK-1, we have shown that Smad1 undergoes specific phosphorylation and translocation to the nucleus, where it directly regulates the expression of Smad1 Id1 and EphB2 responsive genes. [0004] ALK-1 is highly and selectively expressed in endothelial cells and in other highly vascularized tissues such as the placenta or brain. We have demonstrated by real-time Affymetrix and RT-PCR profiling methods that expression of ALK-1 in endothelial cells strongly exceeds the expression of its type II activin and endoglin co-receptors, its ligand TGF-beta-1 or ALK-5. Mutations in ALK-1 are associated with congenital hemorrhagic hemangioma (HHT), which indicates the key role of ALK-1 in controlling the formation or repair of blood vessels. Abdalla et al. J. Med. Genet, 2003, volume 40, pp. 494-502; Sadick et al. Hematologica / The Hematology J., 2005, volume 90, 818828. In addition, two independent studies of ALK-1 knockout mice provide key in vivo evidence for ALK-1 function during angiogenesis. Oh et al. Proc NatI Acad Sci USA, 2000, volume 97, p. 2626-2631; Urness et al. Nature Genetics, 2000, volume 26, p. 328331.
[0005] Angiogenesis is a physiological process involving the formation of new blood vessels from pre-existing vessels and / or circulating endothelial stem cells. This is a normal process during growth and development as well as during wound healing. However, this is also the basic stage of cancer transition from dormancy to malignancy. Hanahan and Folkman, "Patterns and Emerging Mechanisms of the Angiogenic Switch During Tumorigenesis," Cell, 86 (3): 353-364, 1996; Carmeliet, "Angiogenesis in Health and Disease," Nature Medicine, 9 (6): 653-660, 2003; Bergers and Benjamin, "Tumoreigenesis and the Angiogenic Switch," Nature Reviews, 3: 401-410, 2003. In diseases such as cancer, the body loses its ability to maintain balanced angiogenesis. New blood vessels nourish affected tissues, destroy healthy tissues, and in some cancers, new vessels can allow cancer cells to leak into the circulation and colonize other organs (cancer metastases). Angiogenesis inhibitors, including monoclonal antibodies (mAbs), are a very promising class of drugs directed against this abnormal process to block or slow tumor growth.
[0006] In addition to the role in solid tumor growth and metastasis, other noteworthy conditions with the angiogenic component are for example arthritis, psoriasis, age-related macular neovascular degeneration, and diabetic retinopathy. Bonnet et al. "Osteoarthritis, Angiogenesis and Inflammation," Rheumatology, 2005, vol. 44, pp. 7-16; Creamer et al. "Angiogenesis in psoriasis," Angiogenesis, 2002, volume 5, pp. 231-236; Clavel et al.

Rheumatol., 2004, volume 16, pp. 338-343; Ng et al. "Targeting angiogenesis, the underlying disorder in neovascular age-related macular degeneration," Can. J. Ophthalmol., 2005, volume 40, pp. 352-368; Witmer et al.

"Angiogenesis and ophthalmic disease," Angiogenesis, 1999, volume 3, pp. 9-14.
[0007] Antiangiogenic therapies are expected to be chronic. Accordingly, targets with highly selective endothelial activity, such as ALK-1, are preferred to reduce cachexia resulting from side effects. In addition, given the significant discrepancy between ECD ALK-1 and ECD of other members of the ALK family, it is expected that mAbs generated against human ALK-1 ECD will be selectively targeted for ALK-1. Based on these considerations, a monoclonal anti-extracellular ALK-1 domain antibody that can prevent dimerization with the type II receptor and thereby block Smad1 phosphorylation and subsequent transcriptional response in the cell nucleus is highly desirable.
[0008] R&D Systems, Inc. produces and sells anti-human ALK-1 monoclonal antibody (cat. no. MAB370) made from hybridoma obtained by fusing mouse myeloma with B lymphocytes obtained from a mouse immunized with the purified extracellular domain of recombinant human ALK-1 obtained from NSO. We have shown that this antibody does not neutralize the interaction between ALK-1 and TGF-beta-1, nor tolerates Smad1 phosphorylation. Rabbit antisera were generated against a synthetic peptide corresponding to a portion of the ALK-1 intracellular juxtaposition region (amino acid residues 145-166), conjugated with keyhole limpet hemocyanin (KLH) (US Patent No. 6692925) and against the entire extracellular ALK-1 domain outside the leader sequence (Lux et al., J. Biol. Chem., 1999, volume 274, pp. 9984-9992). Abdalla et al. (Human Mol. Gen., 2000, volume 9, pp. 1227-1237) report the production of a polyclonal anti-ALK-1 antibody using a recombinant vaccinia virus construct. R&D Systems, Inc. produces and sells polyclonal anti-human ALK-1 antibody (cat. no. AF370) made in goats immunized with the purified extracellular domain of recombinant human ALK-1 derived from NS0.
[0009] There have been no reports to date of fully human monoclonal anti-ECD ALK-1 antibodies and no one has demonstrated the efficacy of any anti-ECD ALK-1 monoclonal antibody in clearing the ALK-1 / TGFbeta-1 / Smad1 signaling pathway.

Brief description of the drawings [0065]
Figure 1 shows an example of epitope binding data. Antibody 1.12.1 (M29I / D19A) was injected for 10 minutes, and then for a further 10 minutes, antibody 1.12.1 (M29I / D19A) was injected. The maximum response to a 20 minute injection of this antibody was thus determined. This maximum response to a 20-minute injection was determined in a similar manner for the antibody
1.27.1. Antibody 1.12.1 (M29I / D19A) was injected for 10 minutes, followed by the injection of 1.27.1 antibody for 10 minutes. If the overall response is between the specified maximum responses, then these two antibodies must bind to the same epitope. If the overall response exceeds the highest maximum response, then these antibodies must bind to different epitopes. The experiment was then repeated with the injection order reversed, as described in Example 9.

1.12.1 (M29I) refers to the variant mAb 1.12.1, which was an expressed recombinant mAb containing a single specific amino acid mutation in which methionine at position 29 in the heavy chain was replaced with isoleucine.
1.12.1 (D19A) refers to the variant mAb 1.12.1, which was an expressed recombinant mAb containing a single specific amino acid mutation in which aspartic acid at position 19 in the light chain was replaced with alanine.
[0072] As used herein, the term "abnormal cell growth", unless otherwise stated, refers to cell growth that is independent of normal regulatory mechanisms (e.g., loss of contact inhibition).
[0073] The term "contiguous" as used herein refers to nucleotide sequences that are directly linked to each other without any nucleotides between them. For example, the 5'-AAAAA-3 'pentanucleotide is adjacent to the 5'-TTT-3' trinucleotide when they are connected in such a way: 5'-AAAAATTT-3 'or 5'-TTTAAAAA-3', but not when they are connected in this way: 5'-AAAAACTTT-3 '.
[0074] The term "agent" is used herein to mean a chemical compound, a mixture of chemical compounds, a biological macromolecule or an extract made from biological materials.
[0075] The term "alleviating" a disease, disorder or condition as used herein means reducing the severity of the symptoms of the disease, disorder or condition. This includes, but is not limited to, the effect on tumor size, growth and / or mass, extent or progression of metastases, and the like, in a patient compared to the same parameters in a patient before or in the absence of a treatment.
[0076] As used herein, the abbreviation "Id1" refers to a specific downstream ALK-1 target gene, the Id1 gene, which is important for angiogenesis. The Id1 gene has been reported to control the angiogenesis pathway in certain cancers excluding the production of the thrombospondin-1 (TSP-1) protein, a naturally occurring angiogenesis suppressor. For example, it has been reported that the Id1 gene, which is highly expressed in melanoma, breast, head and neck cancer, brain, cervix, prostate, pancreas and testicles, results in reduced TSP1 expression and increased tumor blood vessel formation. Volpert, Olga V. et al., "Id1 regulates angiogenesis through transcriptional repression of thrombospondin-1," Cancer Cell, Dec. 2002, volume 2, pp. 473-483.
[0077] The term "Smad" as used herein refers to domain Smad proteins present in many species from nematodes to humans. These highly conserved proteins contain an MH1 N-terminal domain that contacts DNA and is separated by a short linker region from the MH2 C-terminal domain that exhibits striking similarity with the forkhead-associated domain (FHA). The FHA and Smad (MH2) domains have a common structure consisting of a two-layer sandwich with eleven beta threads with Greek key topology. Smad proteins mediate signal transduction by TGF-beta / activin / BMP-2/4 cytokines from Ser / Thr receptor protein kinases on the cell surface to the nucleus. Smad proteins are divided into three functional classes: Smad receptors regulated by receptors (R-Smad), including Smad1, -2, -3, -5 and -8, each of which is involved in a ligand-specific signaling pathway; comediator Smad (co-Smad) proteins, including Smad4, which interact with R-Smad proteins by participating in signal transduction; and inhibitory Smad (I-Smad) proteins, including Smad-6 and -7, which block the activation of R-Smad and Co-Smad proteins, negatively regulating signaling pathways.
[0078] As used herein, the term "TGF-beta" refers to transforming growth factor beta, which is a family of multifunctional cytokines (TGF-beta 1-5) that regulate cell growth and differentiation. Transforming growth factor (TGF) is one of many growth factors described that exist in nature. It plays a key role in "SCID" mice with severe combined immunodeficiency. Many cells synthesize TGF-beta, and basically all have receptors specific for this peptide.
TGF-beta regulates the effects of many other peptide growth factors and determines the positive or negative direction of their effects. TGF-beta is a tumor suppressor cytokine that inhibits growth in epithelial cells. TGF-β may also act as a tumor promoter by causing transformation from epithelium to mesenchyme.
TGF-β inactivates several proteins involved in cell cycle management and thus exerts its growth inhibitory effect on epithelial cells, leading to their arrest in the G1 phase of the cell cycle. This protein works as a homodimer connected by disulfide bridges. Its sequence is characterized by the presence of several C-terminal cysteine residues that form disulfide linking bonds arranged in a node-like structure. A similar "cystine node" system has been noticed in the structures of some enzyme and neurotoxin inhibitors that bind to voltage-gated Ca channels<sup>2+</sup>, although their exact structure varies. TGF-beta genes are expressed differently, suggesting that different TGF-beta variants may have distinct physiological functions in vivo.
[0079] As used herein, the term "TGF-beta 1" refers to a transforming type 1 receptor growth factor that is a peptide of 112 amino acid residues obtained by proteolytic cleavage from the C-terminus of a precursor protein. Examination of TGF-beta 1 mRNA levels in adult mouse tissues indicates that this expression is highest in the spleen, lung and placenta. TGF-beta 1 is thought to play an important role in pathological processes.
[0080] The term "SCID" as used herein refers to mice with severe combined immunodeficiency.
[0081] The term "HUVEC" as used herein refers to human umbilical vein endothelial cells.
[0082] As used herein, "amino acids" are represented by their full names, their corresponding three-letter codes, or their corresponding one-letter codes, as indicated in the following table:

[0083] In the present application, twenty basic amino acids and their abbreviations are consistent with standard use. See Immunology-A Synthesis (2nd Edition, ES Golub and DR Gren, Ed., Sinauer Associates, Sunderland, Mass. (1991)), [0084] A "conservative amino acid substitution" is one in which the amino acid residue is substituted by another residue amino acid having a side chain R group with similar chemical properties (e.g., charge or hydrophobicity). In general, conservative amino acid substitution will not substantially change the functional properties of a protein. In cases where two or more sequences differ from each other by conservative substitutions, the percentage identity or degree of sequence similarity may be increased to correct for the conservative nature of the substitution. Methods for such matching are well known to those skilled in the art. See, e.g., Pearson, Methods Mol. Biol. 243: 307-31 (1994).
[0085] Examples of groups of amino acids that have side chains with similar chemical properties include 1) aliphatic side chains: glycine, alanine, valine, leucine and isoleucine; 2) aliphatic-hydroxyl side chains: serine and threonine; 3) side chains containing amide moieties: asparagine and glutamine; 4) aromatic side chains: phenylalanine, tyrosine and tryptophan; 5) basic side chains: lysine, arginine and histidine; 6) acidic side chains: aspartic acid and glutamic acid; and 7) sulfur-containing side chains: cysteine and methionine. Preferred groups for conservative amino acid substitutions are: valine-leucineisoleucine, phenylalanine-tyrosine, lysine-arginine, alanine-valine, glutamate, aspartate and asparagine-glutamine.
[0086] Alternatively, the conservative replacement is any change having a positive value in the PAM250 log-probability matrix disclosed in Gonnet et al., Science 258: 1443-45 (1992), "Moderately conservative" replacement is any change having a non-negative value in the log matrix -prawdopodobieństwa
PAM250.
[0087] In some embodiments, the amino acid substitution in the anti-ALK-1 antibody or antigen-binding portion thereof is one that (1) decreases susceptibility to proteolysis, (2) reduces susceptibility to oxidation, (3) changes binding affinity to form protein complexes, and (4) confer or modify other physicochemical or functional properties of such analogues, but still retain the specificity of binding to ALK-1. Analogs may contain different substitutions in the normal peptide sequence. For example, in a normally occurring sequence, for example, in a portion of a polypeptide outside of the domain (s) involved in intermolecular interactions, single or multiple amino acid substitutions, preferably conservative amino acid substitutions, can be made. Alternatively, amino acid substitutions can be made in the domain (s) that are involved in intermolecular interactions that can improve the activity of the polypeptide. Conservative amino acid substitution should not substantially alter the structural properties of the parent sequence, e.g. amino acid replacement should not alter the anti-parallel β-sheet structure that creates the immunoglobulin binding domain found in the parent sequence, nor damage other types of secondary structures that the parent sequence is characterized by. In general, glycine and proline will not be used in the anti-parallel β-sheet structure. Examples of known in the art of secondary and tertiary polypeptide structures are described in Proteins. Structures and Molecular Prin ciples (Creighton, Ed., WH Freeman and Company, New York (1984)); Introduction to Protein Structure (C. Branden and J. Tooze, ed., Garland Publishing, New York, NY (1991)); and Thomton et al., Nature 354: 105 (1991), [0088] Sequence similarity for polypeptides, which is also referred to as sequence identity, is usually measured using sequence analysis software. Protein analysis software aligns similar sequences using measures of similarity attributed to various substitutions, deletions, and other modifications, including conservative amino acid substitutions. For example, GCG contains programs such as "Gap" and "Bestfit" that can be used with default parameters to determine sequence homology or sequence identity between closely related polypeptides, such as homologous polypeptides from different species of organisms, or between wild-type protein and his mutein. See, e.g., GCG Version
6.1. Polypeptide sequences can also be compared using FASTA using default or recommended parameters, the FASTA program in GCG Version 6.1. (e.g., FASTA2 and FASTA3) provides alignment and percent sequence identity of the best overlap regions between the query and wanted sequence (Pearson, Methods Enzymol. 183: 63-98 (1990); Pearson, Methods Mol. Biol. 132: 185-219 (2000)). Another preferred algorithm when comparing the inventive sequences with a database containing a large number of sequences from different organisms is the BLAST computer program, especially blastp or tblastn, using default parameters. See, e.g., Altschul et al., J. Mol. Biol. 215: 403-410 (1990); Altschul et al., Nucleic Acids Res. 25: 3389-402 (1997).
[0089] The length of polypeptide sequences compared for homology will generally be at least about 16 amino acid residues, usually at least about 20 residues, more usually at least about 24 residues, most often at least about 28 residues, and preferably more than about 35 residues. When searching a database containing sequences from a large number of different organisms, it is preferable to compare amino acid sequences. The term "analog" as used herein refers to polypeptides that consist of a stretch of at least 25 amino acids that are substantially identical to a portion of the deduced, naturally occurring amino acid sequence and which have at least one of the properties of a naturally occurring polypeptide. Typically, polypeptide analogs contain a conservative amino acid substitution (or addition or deletion) for a naturally occurring sequence. Analogs usually have a length of at least 20 amino acids, preferably at least 50 amino acids or more, and can often be as long as a naturally occurring polypeptide.
[0090] Peptide analogs are widely used in the pharmaceutical industry as non-peptide drugs with properties analogous to the reference peptide. These types of non-peptide compounds are called "peptide mimetics" or "peptidomimetics".
Fauchere, J. Adv. Drug Res. 15:29 (1986); Veber and Freidinger TINS p. 392 (1985); and Evans et al. J. Med. Chem. 30: 1229 (1987). Such compounds are often developed with the help of computer molecular modeling.
[0091] Peptide mimetics that are structurally similar to therapeutically useful peptides can be used to produce an equivalent therapeutic or prophylactic effect. In general, peptidomimetics are structurally similar to a paradigm polypeptide (i.e. a polypeptide that has a biochemical property or pharmacological effect), such as a human antibody, in which optionally one or more peptide bonds have been replaced by a bond selected from the group consisting of: -CH2NH-, -CH2S-, -CH2-CH2-, -CH = CH- (cis and trans), -COCH2-, -CH (OH) CH2- and CH2SO-, by methods well known in the art. Systematic substitution of one or more amino acids in a consensus sequence with a D-amino acid of the same type (e.g. D-lysine instead of L-lysine) can be used to produce more stable peptides. In addition, rigid peptides containing a consensus sequence or a substantially identical consensus sequence variant (Rizo and Gierasch Ann. Rev. Biochem. 61: 387 (1992) can be prepared using methods known in the art, for example by adding internal cysteine residues capable of forming intramolecular disulfide bridges that lead to peptide cyclization. [0092] Intact "antibodies" or "immunoglobulins" (Ig) contain at least two heavy (H) chains (about 50-70 kDa) and two light (L) chains (about 25 kDa) connected together by disulfide bonds. There are only two types of light chains: λ and κ. They are similar in humans, but only one type is present in each antibody. Heavy chains are classified as mu, delta, gamma, alpha or epsilon and determine the antibody isotype as IgM, IgD, IgG, IgA and IgE, respectively. See generally Fundamental Immunology Ch. 7 (Paul, W., ed., 2nd Edition Raven Press, NY (1989)). In a preferred embodiment, the antibody is of the IgG type and the IgG1, IgG2, IgG3 or IgG4 subtype. In a more preferred embodiment, the anti-ALK-1 antibody is of the IgG2 subclass.
[0093] Each heavy chain consists of a heavy chain variable domain (VH) and a heavy chain constant region (CH). The heavy chain constant region consists of three domains, CH1, CH2 and CH3. Each light chain consists of a light chain variable domain (VL) and a light chain constant region. The light chain constant region consists of one domain, CL. In the light and heavy chains, the variable and constant regions are joined by a "J" region of about 12 or more amino acids, wherein the heavy chain also contains a "D" region of about 3 or more amino acids. The VH and VL regions can be further subdivided into hypervariable regions, called "complementarity determining regions" (CDRs), separated by more conserved regions, called "framework regions" (FRs). Each VH and VL consists of three CDR and four FR regions, arranged from amino to carboxy in the following order FR1, CDR1, FR2, CDR2, FR3, CDR3, FR4. The allocation of amino acids to each domain is in accordance with the definition of Kabat, Sequences of Proteins of Immunological Interest (National Institutes of Health, Bethesda, MD (1987 and 1991)) or Chothia and Lesk, J. Mol. Biol. 196: 901-917 (1987); Chothia et al., Nature 342: 878-883 (1989).
[0094] The variable domains of each heavy / light chain pair (VH and VL) form the antigen binding site of the antibody that interacts with the antigen. Thus, an intact antibody, for example IgG, for two binding sites. In addition to bifunctional or dual specificity antibodies, the two binding sites are the same. Antibody constant regions can mediate the binding of immunoglobulin to host tissues or factors, including various cells of the immune system (e.g. effector cells) and the first component (Clq) of the classical complement system.
[0095] Antibodies must have sufficient antigen binding diversity to recognize every possible pathogen (multiple V regions) while maintaining the biological effectiveness of their C regions (several C regions). Ig genes are randomly assembled from gene segments, which makes it possible to use multiple V regions with several C regions. Gene segments encoding kappa and lambda Ig H chains are located on three different chromosomes. During B-lymphocyte development, recombinase enzymes remove introns and some exons from DNA and assemble segments into functional Ig genes.
[0096] The Ig gene segments in mammals are arranged in groups of "variable" (V), "diversity" (D), "joining" (J) and "constant" (C) exons. Each of the V kappa (Vk) segments encodes the first two CDR regions and three FRs from the V region of the kappa chain, and several residues from CDR3. Each of the J kappa (Jk) segments encodes the remainder of CDR3 and the fourth FR. C kappa (Ck) encodes the entire C region of the kappa light chain. DNA encoding the human kappa chain includes about 40 functional V kappa (Vk) segments, five J kappa (Jk) segments and one kappa C segment (Ck) gene segment, as well as some gene segments that contain stop codons ("pseudogens"). Human lambda chain DNA (A) contains about 30 functional V lambda segments (νλ) and four functional sets of the lambda J (lambda ^ λ) and C lambda ^ λ) segments. The specified J lambda 0 ~ λ) always forms a pair with the corresponding C lambda (ϋλ), unlike J kappa (Jk), which always forms a pair with the same
C kappa (Ck). DNA for human H chain includes about 50 functional VH segments, 30 DH segments and six JH segments. The first two CDR regions and the three FR heavy chain variable domains are encoded by VH. CDR3 is encoded by several nucleotides from VH, whole DH and part of JH, while FR4 is encoded by the remainder of the JH gene segment. There are also individual gene segments in DNA for each heavy chain domain and for the transmembrane region of each of the isotypes, arranged in the order in which they are expressed in B lymphocytes.
[0097] The term "polypeptide" includes native or artificial proteins, protein fragments, and polypeptide analogues of the protein sequence. The polypeptide may be monomeric or polymeric.
[0098] The term "isolated protein", "isolated polypeptide" or "isolated antibody" means a protein, polypeptide or antibody that, due to its origin or source of origin (1), is not associated with naturally bound components that accompany them in a state native, (2) are deprived of other proteins of the same species, (3) are expressed by cells from other species, or (4) are not found in nature. Thus, a polypeptide that is chemically synthesized or synthesized in a cell system different from the cell from which it naturally originates will be "isolated" from its naturally associated components. Protein can also be made substantially free of its naturally associated components by isolation using well-known protein purification techniques.
[0099] Examples of isolated antibodies include, but are not limited to, anti-ALK-1 antibody that has been purified for affinity using ALK-1, and anti-ALK-1 antibody that has been synthesized by an in vitro cell line.
[0100] Proteins or polypeptides are "substantially pure", "substantially homogeneous" or "substantially purified" when at least about 60 to 75% of the sample is one type of polypeptide. These polypeptides or proteins can be monomeric or multimeric. A substantially pure polypeptide or protein can usually be about 50%, 60%, 70%, 80% or 90% w / w. protein samples, usually around 95%, and preferably can be over 99% pure. Protein purity or homogeneity can be determined in a variety of methods well known in the art, such as polyacrylamide gel electrophoresis of a protein sample, followed by visualization of a single polypeptide band after gel staining with a dye well known in the art. For some purposes, greater resolution may be provided using HPLC or other methods well known in the art of purification.
[0101] The term "polypeptide fragment" as used herein refers to a polypeptide that contains an amino-terminal and / or carboxy-terminal deletion, but in which the remaining amino acid sequence is identical to the positions corresponding to it in the naturally occurring sequence. In some embodiments, the fragments are at least 5, 6, 8 or 10 amino acids long. In other embodiments, the fragments are at least 14, at least 20, at least 50, or at least 70, 80, 90, 100, 150 or 200 amino acids long. [0102] The term "analog" or "polypeptide analog" as used herein refers to a polypeptide that contains a segment that is substantially identical to a portion of the amino acid reference sequence and has substantially the same function or activity as the reference amino acid sequence. Typically, polypeptide analogs contain a conservative amino acid substitution (or insertion or deletion) relative to the reference sequence. Analogs can be at least 20 or 25 amino acids in length, or they can be at least 50, 60, 70, 80, 90, 100, 150 or 200 amino acids in length or more, and can often be as long as a full-length polypeptide. Some embodiments of the invention include antibody polypeptide fragments or polypeptide analogs containing 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 or 17 substitutions with respect to the amino acid sequence from germ. Fragments or analogues of antibody or immunoglobulin molecules can be readily prepared by those skilled in the art according to the directions in this description.
[0103] As used herein, the term "antigen-binding antibody portion" (or simply "antibody portion") refers to one or more antibody fragments that retain the ability to specifically bind the antigen (e.g., ALK-1 or ECD ALK-1) . It has been shown that the antigen-binding function of an antibody can be performed by fragments of a full-length antibody. Examples of binding fragments encompassed by the term "antigen binding portion of the antibody" include (i) a Fab fragment, a monovalent fragment consisting of the VL, VH, CL and CH1 domains; (ii) the F (ab ') 2 fragment, a divalent fragment comprising two Fab fragments connected by a disulfide bridge in the hinge region; (iii) the Fd fragment consisting of the VH and CH1 domains; (iv) an Fv fragment consisting of the VL and VH domains from a single arm of an antibody, (v) a dAb fragment (Ward et al. (1989) Nature 341: 544-546) which consists of the VH domain; and (vi) an isolated complementarity determining region (CDR). In addition, although the two domains of the Fv fragment, VL and VH, are encoded by separate genes, they can be linked using recombination methods by a synthetic linker that allows them to be produced as a single protein chain in which the VL and VH regions pair to form monovalent molecules (known as a single Fv chain (scFv)); see, e.g., Bird et al. Science 242: 423-426 (1988) and Huston et al. Natl. Acad. Sci. USA 85: 5879-5883 (1988)). Such single chain antibodies are also included in the term "antigen binding portion of the antibody". This also applies to other forms of single chain antibodies, such as diabodies. Diabodies are bivalent dual specificity antibodies in which the VH and VL domains are expressed as a single polypeptide chain, but using a linker that is too short to allow pairs between two domains from the same chain, thereby forcing domains to form pairs with complementary domains from the second chain to form two antigen binding sites (see, e.g., Holliger et al. Proc. Natl. Acad. Sci. USA 90: 64446448 (1993); Poljak et al. Structure 2: 1121-1123 (1994)).
[0104] Further, the antibody or antigen binding portion thereof may be part of larger immunoadhesion molecules formed by covalent or non-covalent binding of the antibody or antibody portion to one or more other proteins or peptides. Examples of such immunoadhesive molecules include the use of the streptavidin core region to form the tFameric scFv molecule (Kipriyanov et al. Human Antibodies and Hybridomas 6: 93-101 (1995)) and the use of a cysteine residue, a marker peptide and a C-terminal polyhistidine tag to form divalent and biotinylated scFv molecules (Kipriyanov et al., Mol. Immunol. 31: 1047-1058 ( 1994)). Other examples include those in which one or more CDR regions from an antibody are introduced into the molecule, covalently or non-covalently, to obtain an immunoadhesin that specifically binds to the antigen of interest, such as ALK-1 or ECD ALK-1. In such embodiments, the CDR region (s) can be introduced as part of a larger polypeptide chain, covalently linked to another polypeptide chain, or non-covalently linked.
[0105] Antibody portions, such as Fab and F (ab ') 2 fragments can be generated from whole antibodies using traditional techniques such as whole antibody digestion with papain or pepsin, respectively. In addition, antibodies, antibody portions and immunoadhesion molecules can be obtained using standard recombinant DNA techniques as described herein.
[0106] The term "human antibody" as used herein means any antibody in which the variable and constant sequences are human sequences. This term includes antibodies with sequences derived from human genes that have been altered, e.g., to lower possible immunogenicity, increase affinity, remove cysteines that could cause unwanted splicing, etc. This term also includes such recombinant antibodies in non-human cells, which may lead to atypical glycosylation of human cells. These antibodies can be produced in various ways as described below.
[0107] As used herein, the term "neutralizing antibody," inhibitory antibody "or antagonist antibody means an antibody that inhibits the ALK-1 / TGF-beta-1 / Smad1 signaling pathway. In a preferred embodiment, the antibody inhibits the ALK-1 / TGF-beta-1 / Smadl signaling pathway by at least 20%, more preferably 40%, more preferably 60%, even more preferably 80% or even more preferably 85%. The neutralizing or inhibitory potential of human anti-ALK-1 antibodies can be determined, for example, on the basis of their ability to inhibit regulation leading to stimulation of a specific downstream ALK-1 specific gene, Id1, as shown in Example 12; for inhibiting Smad1 phosphorylation determined by Western Blot using the Odyssey Infrared Imaging System from the LI-COR Biosciences as shown in Example 13.
[0108] The term "chimeric antibody" as used herein means an antibody that contains regions from two or more different antibodies. For example, one or more CDR regions of the chimeric antibody may be derived from a human anti-ALK-1 antibody. In another example, all CDR regions may be derived from human anti-ALK-1 antibodies. In another example, the CDR regions of more than one human anti-ALK-1 antibody can be combined in a chimeric antibody. For example, the chimeric antibody may comprise CDR1 from the light chain of the first human anti-ALK-1 antibody, CDR2 from the light chain of the second human anti-ALK-1 antibody and CDR3 from the light chain of the third human anti-ALK-1 antibody, and the heavy chain CDRs may be derived from one or more other anti-ALK-1 antibodies. Further, the framework regions may be derived from one of the anti-ALK-1 antibodies from which one or more CDR regions are taken, or from one or more other human antibodies. In addition, as discussed herein before, a chimeric antibody includes an antibody comprising a portion derived from germline sequences of more than one species.
[0109] In some embodiments, the chimeric antibody of the invention is a humanized anti-ALK-1 antibody. The humanized anti-ALK-1 antibody of the invention comprises the amino acid sequence of one or more framework regions and / or the amino acid sequence of at least a portion of the constant region of one or more human anti-ALK-1 antibodies of the invention, and further includes sequences derived from non-human antibodies against ALK-1, for example CDR sequences.
[0110] The term "ELISA" as used herein refers to an enzyme immunoassay. This test is well known to those skilled in the art. Examples of this test can be found in Vaughan, TJ et al., Nature Biotech. 14: 309-314 (1996) as well as in Example 2 of this application.
[0111] The term "surface plasmon resonance" as used herein refers to an optical phenomenon that allows real-time analysis of biospecific interactions based on the detection of changes in protein concentrations on a biosensor matrix, for example using a BIACORE system (Pharmacia Biosensor AB, Uppsala, Sweden and Piscataway, NJ). Further instructions can be found in Jonsson et al., Ann. Biol. Clin. 51: 19-26 (1993); Jonsson et al., Biotechniques 11: 620-627 (1991); Jonsson et al., J. Mol. Recognit. 8: 125-131 (1995); and Johnsson et al., Anal. Biochem. 198: 268-277 (1991).
[0112] The term "affinity" refers to a measure of attraction between an antigen and an antibody. The innate attraction of an antibody to an antigen is usually expressed as a binding affinity equilibrium constant (KD) for a particular antibody-antigen interaction. The antibody is said to specifically bind to an antigen when the KD is <1 mM, preferably <100 nM. K binding affinity constant<sub>D</sub> can be measured by the method after<sub>™</sub> surface plasmon resonance, for example using the BIACORE system<sup>™</sup>as discussed in Examples 7 and 8.
[0113] The term "koff" refers to a dissociation rate constant of a particular antibody-antigen interaction. The koff dissociation rate constant can be measured by surface plasmon resonance, for example using a BIAcore system, as discussed in Examples 7 and 8.
[0114] The term "avidity" refers to the strength of the functional binding of an antibody to its antigen, which is based on both the affinity and valence of the antibody. As used herein, the term describes increased affinity that occurs as a result of multiple antigen binding sites on an immunoglobulin.
[0115] As used herein, the term "molecular selectivity" refers to the binding affinity of the antibody for a specific antigen that is greater than for other antigens. For example, the antibodies of the present invention may be selective for ALK-1 compared to ALK-2 to ALK-7, which means that the binding affinity of this antibody for ALK-1 is at least 2 times higher, e.g. 4 times, 10 times or 50 or 100 times or greater than for ALK-2 to ALK-7. Such binding affinities can be measured using standard techniques known to those skilled in the art.
[0116] The term "epitope" includes any protein determinant capable of specifically binding to an immunoglobulin or T-cell receptor or otherwise interacting with a molecule. Epitope determinants usually consist of chemically active surface groups of molecules such as amino acids or carbohydrates or sugar side chains and usually have specific tertiary structure properties as well as specific charge properties. An epitope can be "linear" or "conformational." In a linear epitope, all sites of interaction between a protein and an interacting molecule (such as an antibody) occur linearly along the primary amino acid sequence of the protein. In a conformational epitope, interaction sites occur on amino acid residues of proteins that are separated from each other. Once the desired epitope on the antigen has been determined, it is possible to generate antibodies for that epitope, e.g. using the techniques described in the present invention. Alternatively, during the discovery process, the production and characterization of antibodies provides information on desired epitopes. Using this information, it is then possible to competitively screen antibodies for binding to the same epitope. The approach to achieving this is to perform cross-competition studies to find antibodies that competitively bind to each other, i.e. the antibodies compete for binding to the antigen. A high-throughput process for "shoveling" antibodies based on cross-competition is described in International Patent Application No. WO 03/48731.
[0117] As used herein, the term "labeling" refers to a method of grouping antibodies based on their antigen binding properties. Assignment of drawers is largely arbitrary, depending on how the observed binding patterns differ for all tested antibodies. Therefore, drawers will not always correlate with epitopes defined by other methods and should not be used to define epitopes.
[0118] The term "compete" as used herein in reference to an antibody, means that the first antibody or antigen-binding portion thereof competes for binding to the antigen with the second antibody or antigen-binding portion thereof, wherein the binding of the first antibody to its associated epitope is detectably reduced in the presence of a second antibody, compared to binding of the first antibody in the absence of a second antibody. The reverse case in which binding of the second antibody to its epitope is detectably reduced in the presence of the first antibody may or may not occur. That is, the first antibody can inhibit the binding of the second antibody to its epitope, without the second antibody inhibiting the binding of the first antibody to its corresponding epitope. However, when each of the antibodies detectably inhibits the binding of the other antibody to its associated epitope or ligand to the same, to a greater or lesser extent, it is said that these antibodies "cross-compete" for binding to the appropriate (- i) epitope (s). Both competing and cross-competing antibodies are encompassed by the present invention. Regardless of the mechanism responsible for such competition or cross competition (e.g., spatial hindrance, conformational change or binding to a common epitope or part thereof, and the like), a person skilled in the art will understand from the information provided herein that such competing and / or competing cross-covered antibodies are included and may be useful in the methods disclosed herein.
[0119] The term "polynucleotide" as used herein means a polymeric form of nucleotides of at least 10 bases in length, ribonucleotides or deoxynucleotides, or a modified form of any type of nucleotide. The term includes single and double stranded forms.
[0120] The term "isolated polynucleotide" as used herein means a polynucleotide of genomic, cDNA or synthetic origin, or some combination thereof, which "isolated polynucleotide" due to its origin (1) is not associated with all or some polynucleotides with which this "isolated polynucleotide" occurs in nature, (2) it is operably linked to a polynucleotide with which it is not connected in nature, or (3) does not occur in nature as part of a larger sequence.
[0121] The term "naturally occurring nucleotides" as used herein includes deoxyribonucleotides and ribonucleotides. The term "modified nucleotides" as used herein includes nucleotides with modified or substituted sugar groups and the like. The term "oligonucleotide linkages" as used herein includes oligonucleotide linkages such as phosphorothioate, dithiophosphate, selenophosphate, diselenophosphate, thioanilophosphate, anilophosphate, phosphoramidate and the like. See, e.g., LaPlanche et al., Nucl. Acids Res. 14: 9081 (1986); Stec et al., J. Am. Chem. Soc. 106: 6077 (1984); Stein et al., Nucl. Acids Res. 16: 3209 (1988); Zon et al., Anti-Cancer Drug Design 6: 539 (1991); Zon et al., Oligonucleotides and Analogues: A Practical Approach, pp. 87-108 (F. Eckstein, Ed., Oxford University Press, Oxford England (1991)); U.S. Patent No. 5,151,510; Uhlmann and Peyman, Chemical Reviews 90: 543 (1990). If required, the oligonucleotide may contain a detection tag.
[0122] "Operably linked" sequences include both expression control sequences that are adjacent to a given gene and expression control sequences that act in trans or from a distance in controlling a given gene.
[0123] The term "expression control sequence" as used herein means polynucleotide sequences that are necessary for the expression and processing of the coding sequences to which they are ligated. Expression control sequences include the appropriate transcription initiation sequences, transcription termination, promoter and enhancer; effective signals for RNA processing, such as signals for slicing and polyadenylation; cytoplasmic mRNA stabilizing sequences; sequences that enhance translation efficiency (i.e., Kozak consensus sequence); sequences that enhance protein stability; and, if desired, protein secretion enhancing sequences. The nature of such control sequences varies depending on the host organism; in prokaryotes, such control sequences typically include a promoter, ribosome binding site and transcription termination sequence; in eukaryotes, such control sequences typically include promoters and transcription termination sequences. The term "control sequences" is intended to include at least all components whose presence is necessary for expression and processing, and may also include additional components whose presence is beneficial, for example, leader sequences and fusion partner sequences.
[0124] The term "vector" as used herein means a nucleic acid molecule capable of transporting another nucleic acid to which it is attached. In some embodiments, the vector is a plasmid, i.e. a circular double-stranded segment of DNA into which additional DNA segments can be inserted. In some embodiments, the vector is a viral vector, wherein additional DNA segments can be ligated into the viral genome. In some embodiments, the vectors are capable of autonomous replication in the host cell into which they have been introduced (e.g., bacterial vectors having a bacterial origin of replication and mammalian episomal vectors). In other embodiments, the vectors (e.g., mammalian non-episomal vectors) may integrate into the host cell genome after they have been introduced into the host cell, and thus replicate together with the host genome. In addition, some vectors are capable of directing the expression of genes with which they are operably linked. Such vectors are referred to herein as "recombinant expression vectors" (or simply "expression vectors"). [0125] The term "recombinant host cell" (or simply "host cell") as used herein means a cell into which the recombinant expression vector has been introduced. It should be understood that "recombinant host cell" and "host cell" mean not only the cell in question, but also the progeny of such a cell. As modifications due to mutation or environmental influences may occur in subsequent generations, such offspring may not actually be identical to the stem cell, but are still included in the term "host cell" as used herein.
[0126] As used herein, "germline" refers to the nucleotide and amino acid sequences of genes and antibody gene segments that are passed on from parents to offspring through germ cells. This germline sequence is distinguished from nucleotide sequences encoding antibodies in mature B cells that have been altered by recombination and hypermutation during B cell maturation. An antibody that "utilizes" a particular germline has the nucleotide or amino acid sequence that is most similar to the nucleotide sequence of the germline or amino acid sequence that the first one specifies. Such antibodies are often mutated compared to the germline sequence.
[0127] The term "percent sequence identity" in the context of a nucleic acid sequence means residues in two sequences that are the same when aligned at maximum matching. Comparison of sequence identity can occur over a stretch of at least about nine nucleotides, usually at least about 18 nucleotides, more usually at least about 24 nucleotides, usually at least about 28 nucleotides, even more often at least about 32 nucleotides, and preferably at least about 36 nucleotides , 48 or more nucleotides. There are several different algorithms known in the art that can be used to measure nucleotide sequence identity. For example, polynucleotide sequences can be compared using FASTA, Gap or Bestfit, which are programs from the Wisconsin version 10.0 package, Genetics Computer Group (GCG), Madison, Wisconsin. FASTA, which includes, for example, the FASTA2 and FASTA3 programs, provides alignment and percent sequence identity of the best overlap regions between the query and wanted sequence (Pearson, Methods Enzymol. 183: 63-98 (1990); Pearson, Methods Mol. Biol. 132 : 185-219 (2000); Pearson, Methods Enzymol. 266: 227-258 (1996); Pearson, J. Mol. Biol. 276: 71-84 (1998). Unless otherwise specified, the default parameters for the specified program or algorithm are used. For example, the percent sequence identity between nucleic acid sequences can be determined using FASTA with default parameters (word size 6 and NOPAM factor for counting matrix) or using Gap with default parameters as provided in GCG version 6.1.
[0128] Reference to a nucleotide sequence includes its complement, unless otherwise stated. Thus, reference to a nucleic acid with a specific sequence should be understood to include its complementary strand with a complementary sequence.
[0129] The term "substantial similarity" or "substantial sequence similarity" with respect to a nucleic acid or fragment thereof means that with optimal alignment with another nucleic acid (or its complementary strand) taking into account relevant insertions or deletions of nucleotides, the identity of the nucleotide sequences is at least about 85%, preferably at least about 90%, and more preferably at least about 95%, 96%, 97%, 98% or 99% of nucleotide bases, measured by any well-known algorithm for sequence identity, such as FASTA, BLAST or Gap, as discussed above.
[0130] The term "percent sequence identity" in the context of amino acid sequences means residues in two sequences that are the same when aligned at maximum matching. Comparison of sequence identity can occur over a section of at least about five amino acids, usually at least about 20 amino acids, more often at least about 30 amino acids, usually at least about 50 amino acids, more often at least about 100 amino acids, and even more often about 150, 200 or more amino acids. There are several different algorithms known in the art that can be used to measure amino acid sequence identity. For example, amino acid sequences can be compared using FASTA, Gap or Bestfit, which are programs from the Wisconsin version 10.0 package, Genetics Computer Group (GCG), Madison, Wisconsin.
[0131] As used herein for polypeptides, the term "substantial identity" or "substantial similarity" means that two amino acid sequences, when optimally matched, such as using GAP or BESTFIT programs at the default gap weights provided in these programs , are at least 70%, 75% or 80% identical, preferably at least 90% or 95%, and more preferably at least 97%, 98% or 99%. In some embodiments, residue positions that are not identical differ by conservative amino acid substitutions.
[0132] The term "signal sequence", also called a signal peptide, leader peptide, refers to a segment of about 15 to 30 amino acids at the N-terminus of a protein that allows secretion of this protein (passage through the cell membrane). The signal sequence is deleted after protein secretion.
[0133] As used herein, the terms "tag" or "labeled" refer to the introduction of another molecule into an antibody. In one embodiment, the label is a detectable marker, e.g., the introduction of a radiolabeled amino acid or attachment to a polypeptide of biotinyl groups that can be detected using labeled avidin (e.g., streptavidin containing a fluorescent marker or enzymatic activity that can be detected by optical or colorimetric methods). In another embodiment, the label or marker may be therapeutic, e.g., drug conjugate or toxin. Various methods for labeling polypeptides and glycoproteins are known in the art and can be used. Examples of labels for polypeptides include, but are not limited to, radioisotopes or radionuclides (e.g.<sup>3</sup>H <sup>14</sup>C <sup>15</sup>N <sup>35</sup>S <sup>90</sup>Y <sup>99</sup>tc <sup>111</sup>in, <sup>125</sup>AND, <sup>131</sup>I), fluorescent markers (e.g. FITC, rhodamine, lanthanide phosphors), enzyme markers (e.g. horseradish peroxidase, β-galactosidase, luciferase, alkaline phosphatase), chemiluminescent markers, biotinyl groups, predetermined polypeptide epitopes recognized by e.g. . leucine zipper pair sequences, secondary antibody binding sites, metal binding domains, epitope tags), magnetic agents such as gadolinium chelates, toxins such as pertussis toxin, taxol, cytochalazine B, gramicidin D, ethidium bromide, emetin, mitomycin , etoposide, tenoposide, vincristine, vinblastine, colchicine, doxorubicin, daunorubicin, dihydroxyanthracedione, mitoxantrone, mitramycin, actinomycin D, 1-aldestrotosterone, glucocorticoids, procaine, tetracaine, lidocaine, propranolol and puromycin and their analogues or homologues. In some embodiments, the tags are attached via spacer arms of varying lengths to reduce potential spatial hindrance.
[0134] The term "primates" refers to non-human primates that includes apes and monkeys, with improved development of hands and feet, a short nose, and a large brain. The order of non-human primates includes humans, apes, monkeys, and lower primates.
[0135] A "therapeutically effective amount" refers to that amount of therapeutic agent administered that to some extent alleviates one or more of the symptoms of the disorder being treated. With respect to the treatment of cancer, a therapeutically effective amount refers to an amount that has at least one of the following effects: tumor size reduction; inhibiting (i.e., slowing to some extent, preferably stopping) tumor metastasis; inhibiting to some extent (i.e., slowing to some extent, preferably stopping) tumor growth, and alleviating to some extent (or preferably eliminating) one or more symptoms associated with cancer.
[0136] "Treat", "treating" or "therapy" refers to a method of alleviating or abolishing a biological disorder and / or its associated symptoms. In relation to cancer, these terms simply mean that the life expectancy of an affected individual will be increased or one or more of the symptoms of the disease will be reduced.
[0137] "Contacting" refers to bringing together the antibody or antigen-binding portion thereof of the present invention and the target ALK-1, or epitope thereof, in such a way that the antibody can affect the biological activity of ALK-1. Such "contacting" can be achieved "in vitro", ie in a test tube, petri dish or similar. In the test, contacting may include only the antibody or antigen binding portion thereof and ALK-1 or epitope thereof, or may include whole cells. Cells may also be maintained or cultured in cell culture vessels and in this environment contacted with the antibodies or antigen-binding portions thereof. In this context, before attempting to use a particular antibody in vivo on more complex living organisms, the ability of the antibody or antigen-binding portion thereof to affect an ALK-1 related disorder, e.g., the IC50 value of that antibody, can be determined. For cells that are outside the body, there are many methods for contacting ALK1 with antibodies or antigen-binding portions thereof, and they are well known to those skilled in the art.
[0138] The abbreviation "FACS" refers to fluorescence activated cell sorting. The abbreviation FACS and flow cytometry are used interchangeably. Fluorescent labeling allows you to study the structure and function of cells. Immunofluorescence, the most widely used, involves staining cells with antibodies conjugated to fluorescent dyes such as fluorescein and phycoerythrin. This method is often used to label molecules on the surface of cells, but antibodies can be directed to target molecules in the cytoplasm. In direct immunofluorescence, the anti-molecule antibody is directly conjugated to a fluorescent dye and the cells are stained in one step. In indirect immunofluorescence, the primary antibody is unlabelled and a second antibody conjugated to a fluorescent dye that is specific for the first antibody is added.
Anti-ALK-1 Antibodies [0139] This disclosure relates to isolated neutralizing anti-ALK-1 monoclonal antibodies or antigen-binding portions thereof that bind to primate ALK-1, preferably to primate ALK-1 ECD, more preferably to human ALK-1 ECD. In a preferred embodiment, the invention relates to isolated neutralizing antibodies that are fully human monoclonal antibodies, or antigen-binding portions thereof. Preferably, human antibodies are recombinant human anti-ALK-1 antibodies that have greater affinity for ALK-1 than for ALK-2 to ALK-7. In some embodiments, human anti-ALK-1 antibodies are produced by immunizing a transgenic non-human animal, e.g. a rodent, whose genome contains human immunoglobulin genes, such that the transgenic animal produces human antibodies. Various aspects of the invention relate to such antibodies and antigen binding portions and pharmaceutical compositions thereof as well as nucleic acids, recombinant expression vectors and host cells for forming such antibodies and antigen binding portions. Methods of using the antibodies and antigen-binding portions of the present disclosure for abolishing the ALK-1 / TGF-beta-1 / Smad1 signaling pathway or for detecting ALK-1, in vitro or in vivo, are also encompassed by this disclosure. [0140] The anti-ALK-1 antibody of the invention may comprise a human kappa or lambda light chain or an amino acid sequence derived therefrom. In some cases involving the kappa light chain, the light chain variable domain (VL) uses the human A27, A2, A1, A3, B3, B2, L1 or L2 VK gene. In some cases, the light chain uses the human VK L1 gene and the human JK 4 gene; human VK A27 gene and human JK 5 gene or human JK 4 gene; human VK B3 gene and human JK 1 gene; human VK L2 gene and human JK 3 gene; human VK A2 gene and human JK 1 gene; human VK A3 gene and human JK 4 gene; human VK A1 gene and human JK 1 gene; human VK B2 gene and human JK 4 gene: or human VK A2 gene and human JK 1 gene.
[0141] In some embodiments, the VL anti-ALK-1 antibody comprises one or more amino acid substitutions, deletions, or insertions relative to the germline VK amino acid sequence. In some embodiments, the VL anti-ALK1 antibodies contain 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 or 15 amino acid substitutions relative to the germline VK amino acid sequence. In some cases, one or more germline substitutions are in the light chain CDRs. In certain embodiments, the amino acid substitutions in the VK relative to the germline are at one or more of the same positions as the germline substitutions found in any one or more VL antibodies provided herein as shown, for example in Figure 7. In some embodiments, the amino acid changes are in one or more of the same positions, but include a different substitution than that of the reference antibody.
[0142] In some cases, germline substitutions occur at one or more of the same positions as germline substitutions at any of the 1.11.1 VL antibodies; 1.12.1; 1.12.1 (RWT); 1.13.1;
1.14.1; 1.151.1; 1.162.1; 1.183.1; 1.27.1; 1.29.1; 1.31.1; 1.8.1; 1.9.1; 4.10.1; 4.24.1; 4.38.1; 4.58.1; 4.62.1; 4.68.1; 4.72.1; 5.13.1; 5.34.1; 5.53.1; 5.56.1; 5.57.1 and 5.59.1, but substitutions may be conservative amino acid substitutions at this (these) position (s) relative to the amino acid in the reference antibody. For example, if a certain position in one of these antibodies is changed relative to the germline and is glutamate, aspartate may be substituted at this position. Similarly, if the amino acid substitution compared to the germline in the exemplary antibody is serine, you can conservatively substitute threonine for serine at this position. Conservative amino acid substitutions have been discussed above.

In other cases, the light chain of human anti-ALK-1 antibody comprises the VL amino acid sequence of 1.27.1; 1.29.1 or 1.31.1. In some cases, the light chain comprises the amino acid sequence from the beginning of CDR1 to the end of CDR3 of any of the above antibodies.
[0145] In some cases, the light chain may comprise the amino acid sequences of the CDR1, CDR2 and CDR3 regions independently selected from light chain CDR1, CDR2 and CDR3 regions respectively of two or more monoclonal antibodies selected from 1.11.1; 1,121; 1.12.1 (RWT); 1.121 (M29I / D19A; 1.12.1 (M29I); 1.12.1 (D19A); 1.13.1; 1.14.1; 1.151.1; 1.162.1; 1.183.1; 1.27.1; 1.29.1; 1.31. 1; 1.8.1; 1.9.1; 4.10.1; 4.24.1; 4.38.1; 4.58.1; 4.62.1; 4.68.1; 4.72.1; 5.13.1; 5.34.1; 5.53.1; 5.56.1;

[0150] In some cases, the heavy chain comprises the CDR1, CDR2 and CDR3 regions of the heavy chain of antibody 1.11.1; 1.12.1; 1.12.1 (RWT); 1.12.1 (M29I / D19A); 1.12.1 (M29I); 1.12.1 (D19A); 1.13.1; 1.14.1; 1.151.1; 1.162.1; 1.183.1; 1.27.1; 1.29.1; 1.31.1; 1.8.1; 1.9.1; 4.10.1; 4.24.1; 4.38.1; 4.38.1; 4.621; 4.68.1; 4.72.1; 5.13.1; 5.34.1; 5.53.1; 5.56.1; 5.57.1 or 5.59.1, or given CDR regions, each of which has less than 8, less than 6, less than 4, or less than 3 conservative amino acid substitutions and / or a total of three or less than three non-conservative amino acid substitutions. [0151] In some cases, the heavy chain CDRs are independently selected from the CDRs of two or more antibodies selected from 1.11.1; 1.12.1; 1.12.1 (RWT); 1.12.1 (M29I / D19A); 1.12.1 (M29I); 1.12.1 (D19A); 1.13.1; 1.14.1; 1.151.1; 1.162.1; 1.183.1; 1.27.1; 1.29.1; 1.31.1; 1.8.1; 1.9.1; 4.10.1; 4.24.1; 4.38.1; 4.58.1; 4.62.1; 4.68.1; 4.72.1; 5.13.1; 5.34.1; 5.53.1; 5.56.1; 5.57.1 or 5.59.1. In another case, the antibody comprises a light chain as disclosed above and a heavy chain as disclosed above. In a further embodiment, the light chain CDRs and heavy chain CDRs are from the same antibody.
[0152] In various embodiments, anti-ALK-1 antibodies have the full-length heavy chain and light chain amino acid sequence (s), VH and VL amino acid sequences, heavy chain CDR1, CDR2 and CDR3 amino acid sequences, and CDR1, CDR2 and The light chain CDR3 or heavy chain amino acid sequence from the beginning of CDR1 to the end of CDR3 and the light chain amino acid sequence from the beginning of CDR1 to the end of CDR3 of the anti-ALK-1 antibody provided herein.
[0153] One type of amino acid substitution that can be made is the replacement of one or more cysteines in the antibody, which may be chemically reactive, with another residue, such as alanine or serine, which is not limiting. In one embodiment, there is a substitution of non-canonical cysteine. This substitution can be made in the framework domain of the variable domain or in the constant domain of the antibody. In some embodiments, the cysteine is canonical.
[0154] Another type of amino acid substitution that can be made is removal of potential proteolysis sites in the antibody. Such sites may be in the variable region framework region or in the constant domain of an antibody. Substitution of cysteine residues and removal of proteolysis sites may reduce the risk of heterogeneity of the antibody product and thus increase its homogeneity. Another type of amino acid substitution is the removal of asparagine-glycine pairs that create potential deamination sites by changing one or both of these residues.
[0155] In some embodiments, the C-terminal lysine of the heavy chain anti-ALK-1 antibody of the invention is cleaved. In various embodiments of the invention, the heavy and light chains of anti-ALK-1 antibodies may optionally include a signal sequence.
[0156] In one aspect, the disclosure provides twenty-five inhibitory human monoclonal anti-ALK-1 antibodies and hybridoma cell lines that produce them.

1.162.1, 1.31.1, 4.62.1 or 4.72.1.
[0157] Antibodies recognize surface exposed epitopes or antigens based on regions with a linear (primary) sequence or a structural (secondary) sequence. The BIAcore method was used to define the functional epitope system and determine the epitope exclusivity of exemplary anti-ALK-1 antibodies of this invention.

<td colspan="9">1.12.1 (M29I / D19A) refers to an anti-ALK-1 antibody containing a single specific heavy chain mutation where methionine at position 29 has been replaced with isoleucine and a single specific light chain mutation where aspartic acid at position 19 has been replaced with alanine as described in Example 4. 1.12.1 refers to the mAb 1.12.1 variant that has been isolated from a hybridoma. 1.12.1 (rWT) refers to the variant mAb 1.12.1 that was expressed as the recombinant mAb described in Example 3.</td>
[0159] The invention further provides heavy and / or light chain variants of the above-mentioned human anti-ALK-1 antibodies comprising one or more amino acid modifications. In the designations of these variants, the first letter is the single letter amino acid symbol of the naturally occurring antibody chain, the number refers to the amino acid position (where the first position is the N-terminal amino acid of FR1), and the second letter is the single letter amino acid symbol of the variant. [0160] In yet further embodiments, the invention includes antibodies comprising variable domain amino acid sequences with sequence identity over 80%, over 85%, over 90%, over 95%, over 96%, over 97%, over 98%, or over 99% of the amino acid sequence of the variable domain of any of the above human anti-ALK-1 antibodies.
Class and subclass of anti-ALK-1 antibodies [0161] The class and subclass of anti-ALK-1 antibodies can be determined by any method known in the art. In general, the class and subclass of antibodies can be determined using antibodies that are specific for the particular class and subclass of the antibody. Such antibodies are commercially available. Class and subclass can be determined by ELISA, Western Blot as well as other techniques. Alternatively, the class and subclass can be determined by sequencing all or part of the constant domains of the heavy and / or light chains of antibodies by comparing their amino acid sequences with known amino acid sequences of immunoglobulins of different classes and subclasses, and determining the class and subclass of these antibodies.
[0162] The class of anti-ALK-1 antibody obtained as described above can be switched to another. In one aspect of the invention, the nucleic acid molecule encoding VL or VH is isolated using methods well known in the art such that it does not include a nucleic acid sequence encoding CL or CH. "Antibody Engineering" (Kontermann and Dubel, Ed., Springer-Verlag, Berlin (2001)). The nucleic acid molecules encoding VL or VH are then operably linked to the nucleic acid sequence encoding respectively CL or CH from another class of immunoglobulin molecules. This can be accomplished using a vector or nucleic acid molecule that contains the CL or CH chain as described above. For example, an anti-ALK-1 antibody that was originally IgM class can be switched to IgG class. Class switching can be further used to convert one IgG subclass to another, e.g. from IgG1 to IgG2. A preferred method of producing an antibody of the invention comprising the desired isotypes includes the steps of isolating a nucleic acid molecule encoding an anti-ALK-1 antibody heavy chain and a nucleic acid molecule encoding an anti-ALK-1 antibody light chain, obtaining the heavy chain variable domain, and ligating the heavy chain variable domain to the domain heavy chain constant with the desired isotype, expressing the light chain and ligated heavy chain in the cell, and collecting the anti-ALK-1 antibody with the desired isotype.
[0163] In some embodiments, the anti-ALK-1 antibody is a monoclonal antibody. The anti-ALK-1 antibody may be an IgG, IgM, IgE, IgA or IgD molecule. In a preferred embodiment, the anti-ALK-1 antibody is an IgG antibody and is a subclass of IgG1, IgG2, IgG3 or IgG4. In another preferred embodiment, the antibody is of the IgG2 subclass.
Identification of ALK-1 epitopes recognized by anti-ALK-1 antibodies [0164] This disclosure provides a human anti-ALK-1 monoclonal antibody that binds to ALK-1 and competes or crosses with and / or binds to the same epitope as: ( a) an antibody selected from 1.11.1; 1.12.1; 1.12.1 (RWT);
1.12.1 (M29I / D19A); 1.12.1 (M29I); 1.12.1 (D19A); 1.13.1; 1.14.1; 1.151.1; 1.162.1; 1.183.1; 1.27.1; 1.29.1; 1.31.1; 1.8.1; 1.9.1; 4.10.1; 4.24.1; 4.38.1; 4.58.1; 4.62.1; 4.68.1; 4.72.1; 5.13.1; 5.34.1; 5.53.1; 5.56.1; 5.57.1 and 5.59.1; (b) an antibody that comprises a heavy chain variable domain having the VH domain amino acid sequence from any of SEQ ID NO: 6; 10; 14; 18; 22; 26; thirty; 34; 38; 42; 46; 50; 54; 58; 62; 66; 70; 74; 78; 82; 86; 90 or 104, (c) an antibody that comprises a light chain variable domain with a VL domain amino acid sequence from any of SEQ ID NO: 8; 12; 16; twenty; 24; 28; 32; 36; 40; 44; 48; 52; 56; 60; 64; 68; 72; 76; 80; 84; 88; 92 or 127, (d) an antibody that comprises both the heavy chain variable domain as defined in (b) and the light chain variable domain as defined in (c).
[0165] Using methods known in the art, it can be determined whether the antibody binds to the same epitope or cross-competes for binding to an anti-ALK-1 antibody. In one case, the anti-ALK-1 antibody of the invention is allowed to bind to ALK-1 under saturation conditions, and then the test antibody's ability to bind to ALK-1 is measured. If the test antibody is capable of binding to ALK-1 at the same time as the reference anti-ALK-1 antibody, then the test antibody binds to a different epitope than the reference anti-ALK-1 antibody. However, if the test antibody is not capable of binding to ALK-1 at the same time, then the test antibody binds to the same epitope, overlapping epitope or epitope that lies close to the epitope bound by the anti-ALK-1 antibody of the invention . This experiment can be carried out <sub>™</sub> using ELISA, RIA, BIACORE<sup>™</sup> or flow cytometry. To test whether the anti-ALK-1 antibody cross-competes with another anti-ALK-1 antibody, the two-way competition method described above can be used, i.e. checking that the known antibody blocks the antibody being tested, and vice versa. IN<sub>™</sub> in a preferred embodiment, this experiment is carried out using BIACORE<sup>™</sup>.
Binding affinity of anti-ALK-1 antibodies with ALK-1 [0166] The binding affinity (KD) and dissociation constant (koff) of the anti-ALK-1 antibody or antigen-binding portion thereof of ALK-1 can be determined by methods known in the art. Binding affinity can be measured by ELISA, RIA, flow cytometry or surface plasmon resonance, such as BIACORE<sup>™</sup>. The dissociation constant can be measured by surface plasmon resonance. Preferably, the binding affinity and dissociation constant are measured by surface plasmon resonance. More preferably, binding affinity and dissociation constant<sub>™</sub> measured using BIACORE<sup>™</sup>. Using methods known in the art, it can be determined whether the antibody has substantially the same KD as the anti-ALK-1 antibody. Such methods for determining KD and koff can be used during the initial screening step as well as during subsequent optimization steps.
Inhibition of ALK-1 activity by an anti-ALK-1 antibody [0167] Monoclonal anti-ALK-1 antibodies that inhibit the binding of ALK-1 can be identified using several tests. For example, neutralizing anti-ALK-1 antibodies can be identified by their inhibition of regulation leading to stimulation of a specific downstream ALK-1 target gene, Id1, as described in Example 12. Preferred ALK-1 antibodies have an IC 50 not higher than 500 nM, 300 nM, 200 nM, 150 nM, 100 nM, 50 nM, 20 nM, 10 nM or 1 nM.
[0168] The ability of the anti-ALK antibody to inhibit Smad1 phosphorylation as measured by Western Blott using the Odyssey infrared imaging system as described in Example 13 can also be determined. In various instances of this disclosure, the anti-ALK-1 antibody has an IC50 value in this assay not higher than 250 nM, 200 nM, 150 nM, 100 nM, 50 nM, 20 nM, 10 nM or 1 nM.
Inhibition of angiogenesis by an anti-ALK-1 antibody [0169] In a further embodiment, the anti-ALK antibody or portion thereof inhibits human vascular angiogenesis as demonstrated in SCID mice transplanted with human foreskin tissue into which M24met human melanoma tumor cells are intradermally implanted, as determined in IHC analysis using human CD-31 signaling test, by a factor of at least 40% compared to the control sample, as described in Example 17 and shown in Table 13.
[0170] In another case, the anti-ALK-1 antibody or portion thereof inhibits human angiogenesis as demonstrated in SCID mice transplanted with human foreskin in which collagen was implanted intradermally as determined by IHC analysis using human CD-31 signaling assay , with a factor of at least 50% compared to the control sample as described in Example 16 and shown in Table 12.
Species and molecular selectivity [0171] In a further aspect of the invention, the claimed ALK-1 antibodies exhibit both species and molecular selectivity. According to the information in this specification, species or molecular selectivity for an anti-ALK antibody can be determined using methods well known in the art. For example, species selectivity can be determined using Western blot, surface plasmon resonance, e.g. BIAcore, ELISA, immunoprecipitation or RIA.
[0172] In some cases, the anti-ALK-1 antibody binds to ALK-1 primates with KD, which is at least two times lower than the KD for rodent ALK-1. In another case, the KD value for ALK-1 primates is at least 3 times, at least 10 times, at least 50 times, at least 100 times, at least 200 times, at least 500 times or at least 1000 times lower than KD for rodent ALK-1, measured by flow cytometry.
[0173] In other cases, the anti-ALK-1 antibody exhibits selectivity for ALK-1 compared to ALK-2 to ALK-7. In some embodiments, the anti-ALK-1 antibody does not show any significant specific binding to any protein other than ALK-1. Preferably, the anti-ALK antibody binds to ECD human ALK1.
Methods for producing antibodies and antibody-producing cell lines
Immunogen ALK-1 [0174] In some embodiments, the ALK-1 immunogen or antigen is isolated and / or purified ALK-1. In some embodiments, the ALK-1 immunogen is human ALK-1. In preferred embodiments, the ALK-1 immunogen is ECD human ALK-1. Human ALK-1, or antigenic parts thereof may be prepared according to methods well known in the art, or may be purchased from commercial sellers. The human ALK-1 amino acid and nucleotide sequences are known (see e.g. Registry at Genbank under accession number L17075). The ACVRL1 gene encoding full length ALK-1 is commercially available from Invitrogen Inc., Clone No. IOH21048. For example, R&D Systems, Inc. sells a recombinant human ALK-1 / Fc chimera (catalog number 370-AL) produced by expression of a DNA sequence encoding the amino acid residues 1-118 ECD ALK-1, which DNA sequence was fused to the DNA sequence encoding the human Fc region IgG via a DNA sequence encoding a polypeptide linker in a murine melanoma cell line. The mature recombinant human ALK-1 / Fc chimera is a homodimeric disulfide bonded protein having an Asp 22 amino terminus. In addition, Example 1 describes the production of the ALD-1 His-Tag ECD protein that was used to produce anti-ALK-1 antibody hybridomas in accordance with the present invention.
[0175] In other embodiments, the ALK-1 antigen is a cell in which ALK-1 is expressed or overexpressed. In other embodiments, the ALK-1 antigen is a recombinant protein expressed in yeast, insect cells, bacteria such as E. coli, or other sources using recombinant technology.
Immunization [0176] In some embodiments, human antibodies are produced by immunization with an ALK-1 antigen of a transgenic non-human animal having in its genome partially or fully loci for the heavy chain and light chain of human immunoglobulin. In a preferred embodiment, the non-human living being is an XENOMOUSE® animal. (Abgenix, Inc., Fremont, CA).
[0177] XENOMOUSE® mice are genetic engineered mouse strains that contain large fragments of the heavy and light chain loci of human immuboglobulins and do not produce murine antibodies. See, e.g., Green et al., Nature Genetics 7: 13-21 (1994) and US Patent Nos. 5,916,771, 5,939598, 5,985,615, 5,998,209,
6075181, 6091001, 6114598, 6130364, 6162963 and 6150584. See also WO 91/10741, WO 94/02602, WO 96/34096, WO 96/33735, WO 98/16654, WO 98/24893, WO 98/50433, WO 99/45031, WO 99/53049, WO 00/09560 and WO 00/037504.
[0178] In a further aspect, the invention d provides a method of producing anti-ALK-1 antibodies from non-human living beings and mice by immunizing with the ALK-1 antigen transgenic living beings that contain human immunoglobulin loci. Such living things can be produced using the methods described in the documents cited above. The methods disclosed in these documents can be modified as described in US Patent 5,994619. U.S. Patent 5,994,619 describes methods for the production of new cultured cells and embryonic node cell lines (CICM) from pigs and cows and transgenic CICM cells into which heterologous DNA has been introduced. CICM transgenic cells can be used to produce cloned transgenic embryos, fetuses and offspring. The '619 patent also describes methods for producing transgenic animals that are able to pass heterologous DNA to their offspring. In preferred embodiments of the present invention, the non-human living entities are mammals, preferably rats, sheep, pigs, goats, cattle, horses or chickens.
[0179] XENOMOUSE® mice produce a repertoire of fully human antibodies, such as in adult humans, and produce human antigen-specific antibodies. In some embodiments, the XENOMOUSE® mouse contains approximately 80% of the repertoire of human V antibody genes by introducing human heavy chain and kappa light chain loci fragments with germline configuration and megase base in artificial yeast chromosome (YAC). In other embodiments, XENOMOUSE® mice further contain approximately the entire locus for the human lambda light chain. See Mendez et al., Nature Genetics 15: 146-156 (1997), Green and Jakobovits, J. Exp. Med. 188: 483-495 (1998) and WO 98/24893.
[0180] In some embodiments, the non-human living entities having human immunoglobulin genes are animals carrying a "minilocus" for human immunoglobulin. In the minilocus approach, the exogenous Ig locus is mimicked by the incorporation of single genes from the lg locus. Thus, one or more VH genes, one or more DH genes, one or more JH genes, mu constant domain and second constant domain (preferably constant gamma domain) are constructing a construct for introduction into animal. This approach is described, inter alia, in US Patent Nos. 5545807, 5545806, 5589825, 5625126, 5633425, 5661016, 5770429, 5789650, 5814318, 5591669, 5612205, 5721367, 5789215 and 5643763.
[0181] In another aspect, the invention provides a method of producing humanized anti-ALK-1 antibodies. In some embodiments, non-human living beings are immunized with the ALK-1 antigen in the manner described below and under conditions permitting the production of antibodies. Antibody-producing cells are isolated from living beings, and the nucleic acids encoding the heavy and light chain of a given anti-ALK-1 antibody are isolated from isolated antibody-producing cells or from an immortalized cell line made from such cells. These nucleic acids are then engineered using techniques known to those of skill in the art and further described below to reduce the content of non-human sequences, i.e. humanize the antibody to reduce the immune response in humans.
[0182] The immunization of living things can be carried out by any method known in the art. See, e.g., Harlow and Lane, Antibodies: A Laboratory Manual, New York: Cold Spring Harbor Press, 1990. Methods for immunizing non-human living creatures such as mice, rats, sheep, goats, pigs, cattle and horses are well known in the art. field. See, e.g., Harlow and Lane, supra, and US Patent 5,994,619. In a preferred embodiment, the ALK-1 antigen is administered with an adjuvant to stimulate an immune response. Examples of adjuvants include Freund's complete or incomplete adjuvant, RIBI (muramyl dipeptides) or ISCOM (immunostimulatory complexes). Such adjuvants may protect the polypeptide from being rapidly dispersed by depositing it in a local bed or may contain substances that stimulate the host to secrete chemotactic agents on macrophages and other components of the immune system. Preferably, if the polypeptide is administered, the immunization schedule will include two or more administrations of the polypeptide carried out within a few weeks. Example 2 shows a method for producing anti-ALK-1 monoclonal antibodies in XENOMOUSE® mice.
Production of Antibodies and Antibody-Producing Cell Lines [0183] After immunizing the animal with the ALK-1 antigen, antibodies and / or antibody-producing cells can be obtained from the animal. In some cases, serum containing anti-ALK-1 antibodies is obtained from an animal by bleeding or killing the animal. The serum can be used as it is obtained from the animal, the immunoglobulin fraction can be obtained from the serum or the anti-ALK antibodies can be purified from the serum.
[0184] In some cases, antibody-producing cell lines are generated from cells isolated from the immunized animal. After immunization, the animal is sacrificed and B lymphocytes from the lymph nodes and / or spleen are immortalized in any manner known in the art. Methods of immortalizing cells include, but are not limited to, transfecting them with oncogenes, infecting them with an oncogenic virus, and growing them under conditions of selection of immortalized cells, exposing them to carcinogenic or mutagenic compounds, fusing them with an immortalized cell, e.g., a myeloma cell, and inactivating the suppressor gene. cancer. See, e.g., Harlow and Lane, above. If fusion with myeloma cells is used, these myeloma cells preferably do not secrete immunoglobulin polypeptides (a non-secretory cell line). The immortalized cells are screened using ALK-1 or part thereof. In a preferred case, the pre-screening is carried out using an enzyme immunoassay (ELISA) or radioimmunoassay. An example of ELISA screening is provided in WO 00/37504.
[0185] Cells producing anti-ALK-1 antibodies, e.g., hybridomas, are selected, cloned and further screened for desired properties, including rapid cell growth, high antibody production, and desired antibody properties, as discussed below. Hybridomas can be further propagated in vivo in syngeneic animals, in animals that do not have an immune system, e.g. in nude mice or in vitro cell culture. Methods for selecting, cloning and propagating hybridomas are well known to those skilled in the art.
[0186] In a preferred case, the immunized animal is a non-human animal that expresses human immunoglobulin genes and splenic B lymphocytes are fused to a myeloma cell line of the same species as the non-human animal. In a more preferred case, the immunized animal is XENOMOUSE® and the myeloma cell line is a non-secretory mouse myeloma cell line. In an even more preferred case, the myeloma cell line is P3-X63Ag8.653 (American Cell Culture Collection). See e.g. Example 2.
[0187] Thus, in one case, the invention provides methods for producing a cell line that produces a human monoclonal antibody or fragment thereof directed against ALK-1, including (a) immunizing the non-human transgenic animal described herein, using ALK-1, a portion of ALK -1 or ALK-1 expressing cell or tissue; (b) allowing the animal to induce an ALK-1 immune response; (c) isolating the antibody-producing cells from a transgenic live animal; (d) immortalizing antibody producing cells; (e) generating single monoclonal populations of immortalized antibody producing cells; and (f) screening the immortalized antibody-producing cells to identify an anti-ALK-1 antibody.
[0188] In another aspect, the present disclosure provides a cell line that produces human anti-ALK-1 antibody. In some cases, the cell line is a hybridoma cell line. In some cases, hybridomas are mouse hybridomas as described above. In other cases, hybridomas are produced in a species other than humans and mice, such as rats, sheep, pigs, goats, cattle or horses. In another case, hybridomas are human hybridomas.
[0189] In another case, the transgenic animal is immunized using the ALK-1 antigen, primary cells, e.g. B-cells from spleen or peripheral blood, are isolated from the immunized animal and individual cells producing antibodies specific for the desired antigen are identified. Polyadenylated mRNA is then isolated from each individual cell and subjected to reverse transcription polymerase chain reaction (RT-PCR) using sense primers that attach to variable domain sequences, e.g. degenerate primers that recognize almost all or all of the FR1 regions of human genes heavy and light chain variable domains, and antisense primers that attach to the constant or linker region sequence. The cDNA of the heavy and light chain variable domains is then cloned and expressed in any suitable host cell, e.g., a myeloma cell, as a chimeric antibody with appropriate immunoglobulin constant regions, such as heavy and κ or λ constant domains. See Babcook, JS et al., Proc. Natl. Acad. Sci. USA 93: 7843-48, 1996. Antibodies against ALK-1 can then be identified and isolated as described herein.
[0190] Otherwise, phage display techniques can be used to provide libraries containing antibody repertoire with varying affinity for ALK-1. To produce such repertoires, it is not necessary to immortalize B lymphocytes from the immunized animal. Rather, B cells can be used directly as a DNA source. A mixture of cDNA obtained from B lymphocyte, e.g. derived from the spleen, it is used to produce an expression library, for example, a phage display library transfected into E. coli. The obtained cells are tested for immunoreactivity with ALK-1. Techniques for identifying high affinity human antibody libraries are described by Griffiths et al., EMBO J., 13: 3245-3260 (1994); Nissim et al., Ibid, pp. 692-698 and by Griffiths et al., Ibid, 12: 725-734.
[0191] Finally, clones from the library are identified that give binding affinities with the desired strength for the antigen, and the DNA encoding the product responsible for such binding is recovered and subjected to standard recombinant expression. Phage display libraries can also be built using previously changed nucleotide sequences and searched in a similar way. Typically, cDNA encoding the heavy and light chain for production in the phage library is independently provided or combined to form Fv analogs.
[0192] The phage library is then screened for antibodies with the highest affinities for ALK-1 and genetic material is recovered from the appropriate clone. Subsequent screenings may increase the affinity of the original isolated antibody.

Nucleic Acids [0193] The present invention also includes nucleic acid molecules encoding proprietary anti-ALK-1 antibodies or antigen-binding fragments thereof. In some cases, different nucleic acid molecules encode the anti-ALK-1 immunoglobulin heavy chain and light chain. In other embodiments, the same nucleic acid molecule encodes an anti-ALK-1 immunoglobulin heavy chain and light chain.
[0194] In some embodiments, the claimed nucleic acid molecule encoding the light chain variable domain (V<sub>L</sub>) uses the human Vk A27, A2, B3 or L2 gene.

[0200] In other preferred embodiments, the claimed nucleic acid molecule encodes a heavy chain variable domain (VH) that utilizes the human VH 4-31, VH 3-11 VH 4-61 or VH 4-59 gene sequence or a sequence derived therefrom . In some cases, the nucleic acid molecule uses the human VH 4-31 gene, the human DH6-19 gene and the human JH4B gene.
[0201] In some cases, the nucleic acid molecule encodes an amino acid sequence containing 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or 11 mutations compared to the amino acid sequence from the germline of human V, D genes or J. In some cases, these mutations are in the VH region. In some cases, these mutations are in the CDR regions.
[0202] In some embodiments, the nucleic acid molecule encodes a VH sequence containing one or more amino acid mutations compared to a germline VH sequence that is identical to the amino acid mutations found in the VH of any of monoclonal antibodies 1.12.1; 1.12.1 (RWT); 1.12.1 (M29I / D19A); 1.12.1 (M29I); 1.12.1 (D19A); 1.13.1; 1.14.1; 1.162.1; 1.183.1; 1.27.1; 1.29.1; 1.31.1; 1.9.1; 4.24.1; 4.38.1; 4.58.1; 4.62.1; 4.68.1; 4.72.1 or 5.13.1. In some cases, the nucleic acid encodes at least three amino acid mutations compared to germline sequences that are identical to at least three amino acid mutations found in one of the above-mentioned monoclonal antibodies.
[0203] In some embodiments, the nucleic acid molecule comprises a nucleotide sequence selected from the group consisting of SEQ ID NO: 5, 13, 17, 25, 29, 37, 41, 45, 49, 53, 57, 61, 65, 69, 73 or 103, which codes for the VH amino acid sequence of monoclonal antibody 1.12.1 (M29I / D19A), 1.13.1; 1.14.1; 1.1621; 1.183.1; 1.27.1; 1.29.1; 1.31.1; 1.9.1; 4.24.1; 4.38.1; 4.58.1; 4.62.1; 4.68.1; 4.72.1; 5.13.1 or 1.12.1.
[0204] In some cases, the nucleic acid molecule comprises a nucleotide sequence that encodes the amino acid sequence of one of SEQ ID NO: 2; 6; 10; 14; 18; 22; 26; thirty; 34; 38; 42; 46; 50; 54; 58; 62; 66; 70; 74; 78; 82; 86; 90 or 104. In various preferred cases, the nucleic acid molecule comprises at least a portion of the nucleotide sequence of SEQ ID NO: 1 or 95. In some cases, this portion contains a VH region, a CDR3 region, all three CDR regions, or a contiguous region comprising CDR1-CDR3.
[0205] In some cases, the nucleic acid molecule encodes a VH amino acid sequence that is at least 70%, 75%, 80%, 85%, 90%, 95%, 97%, 98% or 99% identical with the amino acid sequence VH from any of SEQ ID NO: 2; 6; 10; 14; 18; 22; 26; thirty; 34; 38; 42; 46; 50; 54; 58; 62; 66; 70; 74; 78; 82; 86; 90 or 104. The nucleic acid molecules of the present disclosure include nucleic acids that hybridize under highly stringent conditions such as those described above, or which are at least 70%, 75%, 80%, 85%, 90%, 90%, 95%, 97 identical %, 98% or 99% with a nucleic acid encoding the amino acid sequence of SEQ ID NO: 2; 6; 10; 14; 18; 22; 26; thirty; 34; 38; 42; 46; 50; 54; 58; 62; 66; 70; 74; 78; 82; 86; 90, 100 or 104, or with their VH region, or with a nucleic acid comprising the nucleotide sequence of SEQ ID NO: 1, 5, 9, 13, 17, 21, 25, 29, 33, 37, 41, 45, 49, 53, 57, 61, 65, 69, 73, 77, 81, 85, 89, 95, 103, 128 or 129, or with the nucleotide sequence that encodes their VH region. [0206] In a further embodiment, the nucleic acid encodes the full-length heavy chain of an antibody selected from the group consisting of 1.12.1; 1.12.1 (rVVT); 1.12.1 (M29I / D19A); 1.12.1 (M29I); 1.12.1 (D19A); 1.13.1; 1.14.1; 1.162.1; 1.183.1; 1.27.1; 1.29.1; 1.31.1; 1.9.1; 4.24.1; 4.38.1; 4.58: 1; 4.62.1; 4.68.1; 4.72.1 and 5.13.1; or a heavy chain comprising the amino acid sequence of SEQ ID NO: 2. Further, the nucleic acid may comprise the nucleotide sequence of SEQ ID NO: 1 or 95.
[0207] A nucleic acid molecule encoding the heavy or light chain of an anti-ALK-1 antibody or portion thereof as claimed may be isolated from any source that produces such an antibody. In various embodiments, the nucleic acid molecules are isolated from a B lymphocyte that expresses an anti-ALK-1 antibody, obtained from a live animal immunized with ALK-1 or from an immortalized cell obtained from such a B lifmocyte. Methods for isolating nucleic acids encoding antibodies are well known in the art. See, e.g., Sambrook J. and Russell D. Molecular Cloning: A Laboratory Manual, ed. 3, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY (2000). MRNA can be isolated and used to produce cDNA for use in polymerase chain reaction (PCR) or cDNA cloning of antibody genes. In a preferred embodiment, the nucleic acid molecule is isolated from a hybridoma, one of the fusion partners of which is a cell from a transgenic non-human animal, which cell produces human immunoglobulin. In an even more preferred embodiment, the human immunoglobulin producing cell is obtained from an XENOMOUSE® animal. In another embodiment, the human immunoglobulin producing cell is obtained from a transgenic non-human animal and mouse as described above. In another embodiment, the nucleic acid is isolated from a non-transgenic non-human animal. Nucleic acid molecules isolated from a non-transgenic non-human animal may be used, e.g., for humanized antibodies that contain one or more amino acid sequences from the human anti-ALK-1 antibody of the present invention.
[0208] In some instances, the nucleic acid encoding the anti-ALK-1 antibody heavy chain of the invention may comprise a nucleotide sequence encoding a VH domain of the invention fused in frame with a nucleotide sequence encoding a heavy chain constant domain from any source. Similarly, the nucleic acid molecule encoding the light chain of the anti-ALK-1 antibody of the present invention comprises the nucleotide sequence encoding the VL domain of the invention fused in frame with the nucleotide sequence encoding the light chain constant domain from any source.
[0209] In another aspect of this disclosure, nucleic acid molecules encoding heavy (VH) and / or light (VL) chain variable domains are "transformed" into full-length antibody genes. In one case, the nucleic acid molecules encoding the VH or VL domains are converted into full-length antibody genes by inserting them into an expression vector already encoding the heavy chain constant domain (CH) or light chain constant domain (CL), respectively, such that the VH segment is operably linked to the CH segment (s) on this vector and / or the VL segment is operably linked to the CL segment on this vector. In another case, the nucleic acid molecules encoding the VH and / or VL domains are converted into full-length antibody genes by joining e.g. by ligation, a nucleic acid molecule encoding the VH and / or VL domains with a nucleic acid molecule encoding the CH and / or CL domain with using standard molecular biology techniques. The nucleic acid sequences of human immunoglobulin heavy and light chain constant domain genes are known in the art. See e.g. Kabat et al., Sequences of Proteins of Immunological Interest, ed. 5, NIH Publication No. 91-3242, 1991. Nucleic acid molecules encoding full-length heavy and / or light chains can then be expressed from the cell into which the anti-ALK-1 antibody has been introduced and isolated.
[0210] Nucleic acid molecules can be used to recombinantly express large amounts of anti-ALK-1 antibodies. Nucleic acid molecules can also be used to produce chimeric antibodies, dual specificity antibodies, single chain antibodies, immunoadhesins, diabodies, mutated antibodies, and antibody derivatives as described herein below. If the nucleic acid molecules are derived from a non-transgenic non-human animal, these nucleic acid molecules can be used to humanize the antibody, also as described below.
[0211] In a further embodiment, the claimed nucleic acid molecule of the invention is used as a PCR probe or primer for a specific antibody sequence. For example, the nucleic acid can be used as a probe in diagnostic methods or as a PCR primer to amplify DNA regions that can be used, inter alia, to isolate additional nucleic acid molecules encoding anti-ALK-1 antibody variable domains. In some embodiments, the nucleic acid molecules are oligonucleotides. In some embodiments, the oligonucleotides are derived from the highly variable heavy and light chain domains of a given antibody. In some embodiments, the oligonucleotides encode all or part of one or more CDR regions from antibodies 1.12.1; 1.12.1 (RWT); 1.12.1 (M29I / D19A); 1.12.1 (M29I); 1.12.1 (D19A); 1.13.1; 1.14.1; 1.162.1; 1.183.1; 1.27.1; 1.29.1; 1.31.1; 1.9.1; 4.24.1; 4.38.1; 4.58.1; 4.62.1; 4.68.1;
4.72.1 or 5.13.1; or variants thereof as described herein.
Vectors [0212] The disclosure provides vectors containing nucleic acid molecules encoding the heavy chain of an anti-ALK-1 antibody of the invention or an antigen binding portion thereof. The invention also provides vectors containing proprietary nucleic acid molecules encoding the light chain of such antibodies or an antigen binding portion thereof. The disclosure further provides vectors containing nucleic acid molecules encoding fusion proteins, modified antibodies, antibody fragments, and probes thereof.
[0213] In some embodiments, the anti-ALK-1 antibodies of the invention or antigen-binding portions are expressed by inserting DNA encoding part or all of the light and heavy chains obtained as described above in expression vectors, such that these genes are operably linked with necessary expression control sequences, such as transcription and translation control sequences. Expression vectors include plasmids, retroviruses, adenoviruses, adeno-associated viruses (AAVs), plant viruses such as cauliflower mosaic virus, tobacco mosaic virus, cosmids, YAC, EBV-derived episomes, and the like. The antibody gene is ligated into the vector so that the transcription and translation control sequences in the vector perform their intended function of regulating the transcription and translation of the antibody gene. The expression vector and expression control sequences are selected to be compatible with the expression in the host cell used. The antibody light chain gene and antibody heavy chain gene can be inserted into separate vectors. In a preferred embodiment, both genes are inserted into the same expression vector. Antibody genes are inserted into the expression vector using standard methods (e.g. by ligation of complementary restriction sites on an antibody gene fragment and on a vector or ligation of blunt ends when no restriction sites are present).
[0214] A convenient vector is such a vector that encodes a functionally complete human immunoglobulin CH or CL sequence with appropriate restriction sites designed so that any VH or VL sequence can be easily inserted and expressed as described above. In such vectors, splicing usually occurs between the donor splice site in the inserted J region and the acceptor splice site preceding the human C domain, as well as in the splice regions that occur in human CH exons. Polyadenylation and transcription termination occur at native chromosomal sites downstream of the coding regions. The recombinant expression vector can also encode a signal peptide that facilitates secretion of the antibody chain from the host cell. The antibody chain gene may be cloned into a vector such that the signal peptide is linked in-frame to the amino terminus of the immunoglobulin chain. The signal peptide may be an immunoglobulin signal peptide or a heterologous signal peptide (i.e., a signal peptide from a non-immunoglobulin protein).
[0215] In addition to the antibody chain genes, the recombinant expression vectors of the disclosure carry regulatory sequences that control the expression of the antibody chain genes in a host cell. One of ordinary skill in the art will appreciate that the design of the expression vector, including the choice of regulatory sequences, may depend on factors such as the choice of transformed host cell, the desired level of protein expression, etc. Preferred regulatory sequences for expression in a mammalian host cell include viral elements that direct high levels of protein expression in mammalian cells, such as promoters and / or enhancers derived from retroviral LTR, cytomegalovirus (CMV) (such as the CMV promoter / enhancer), virus Simian Virus 40 (SV40) (such as SV40 promoter / enhancer), adenovirus, (e.g. Adenovirus major late promoter (AdMLP)), polyoma and strong mammalian promoters such as native immunoglobulin and actin promoters. For further description of the viral regulatory elements and their sequences, see, e.g., U.S. Patent No. 5,168,062, U.S. Patent No. 4,510,245, and U.S. Patent No. 4,966,815. Methods for expressing antibodies in plants, including promoters and vectors, as well as plant transformations are known in the art. field. See e.g. U.S. Patent 6,517,529. Methods for expressing polypeptides in bacterial or fungal cells, e.g., yeast cells, are also well known in the art.
[0216] In addition to the antibody chain genes and regulatory sequences, the recombinant expression vectors of the invention may carry additional sequences, such as sequences that regulate vector replication in host cells (e.g., origin of replication) and selectable marker genes. The selectable marker gene facilitates the selection of host cells into which the vector has been introduced (see, e.g., US Patent Nos. 4,392,916, 4,634,665 and 5,179,017). For example, a selectable marker gene typically confers host cell into which the vector has been introduced resistance to drugs such as G418, hygromycin or methotrexate. For example, selectable marker genes include the dihydrofolate reductase (DHFR) gene (for use in dhfr host cells in methotrexate selection / multiplication), the neo gene (for selection on G418), and the glutamate synthetase gene.
Non-hybridoma host cells and methods for recombinant protein production [0217] Nucleic acid molecules encoding anti-ALK-1 antibodies and vectors containing these nucleic acid molecules can be used to transfect a suitable mammalian, plant, bacterial or yeast host cell. Transformation can be accomplished using any known method of introducing polynucleotides into a host cell. Methods for introducing heterologous polynucleotides into mammalian cells are well known in the art and include transfection with dextran, calcium phosphate precipitation, polybrene transfection, protoplast fusion, electroporation, encapsulation of the polynucleotide (s) in liposomes and direct injection of DNA into the nucleus. In addition, nucleic acid molecules can be introduced into mammalian cells using viral vectors. Cell transformation methods are well known in the art. See e.g. Methods for transforming plant cells are well known in the art and include, e.g., transformation using Agrobacterium, transformation using a gene shotgun, direct injection, electroporation and viral transformation. Methods for transforming bacterial and yeast cells are also well known in the art.
[0218] Mammalian cell lines available as expression hosts are well known in the art and include many immortalized cell lines available from the American Cell Culture Collection (ATCC). These include Chinese hamster ovary (CHO) cells, NSO cells, SP2 cells, HEK-293T cells, Freestyl e 293 cells (Invitrogen), NIH-3T3 cells, HeLa cells, baby hamster kidney cells (BHK), kidney cells green monkey (COS), human hepatocellular carcinoma cells (e.g. Hep G2), A549 cells and several other cell lines43. Particularly preferred cell lines are selected by determining which cell lines show high expression. Other cell lines that can be used are insect cell lines, such as Sf9 or Sf21 cells. When the recombinant expression vectors encoding the antibody genes are introduced into mammalian host cells, the antibodies are produced by culturing the host cells for a sufficient time to allow expression of the antibody in the host cells or, more preferably, secretion of the antibody into the culture medium in which the host cells are grown. . Antibodies can be recovered from the culture medium using standard protein purification methods. Plant host cells include, e.g., Nicotiana, Arabidopsis, eyelash, maize, wheat, potato, etc. Bacterial host cells include E. coli and Streptomyces species. Yeast host cells include Schizosaccharomyces pombe, Saccharomyces cerevisiae and Pichia pastoris.
[0219] In addition, the expression of the antibodies of the invention from their cell lines can be increased using several known techniques. For example, the glutamate synthetase gene expression system (GS system) is a common approach to enhance expression under certain conditions. The GS system is discussed in full or in part in connection with European patents Nos. 0216846, 0256055, 0323997 and 0338841. [0220] It is possible that antibodies expressed by different cell lines or transgenic living things will differ from each other by glycosylation. However, all antibodies encoded by the nucleic acid molecules provided herein or including the amino acid sequences provided herein are part of the present invention regardless of the glycosylation of the antibodies.
Transgenic Living Animals and Plants [0221] The anti-ALK-1 antibodies of the invention can also be made transgenically by creating a mammal or plant that is transgenic in terms of the heavy and light chain sequences of a given immunoglobulin and producing the antibody in a recoverable form therefrom. Due to transgenic production in mammals, anti-ALK-1 antibodies can be made and recovered from the milk of goats, cows and other mammals. See e.g. U.S. Patent Nos. 5827690, 6756687, 5750172 and 5,741957. In some embodiments, transgenic non-human living entities that contain human immunoglobulin loci are immunized with ALK-1 or an immunogenic portion thereof, as described above. Methods for producing antibodies in plants are described, e.g., in US Patent Nos. 6046037 and 5,959177.
[0222] In certain embodiments, transgenic non-human living creatures are produced by introducing one or more nucleic acid molecules encoding an anti-ALK-1 antibody of the invention into that living creature or plant using standard transgenic techniques. See Hogan and United States Patent 6,414,29, above. The transgenic cells used to create the transgenic animal can be embryonic stem cells or somatic cells or fertilized egg cells. Non-human transgenic organisms may be chimeric, non-chimeric heterozygous and non-chimeric homozygous. See, e.g., Hogan et al., Manipulating the Mouse Embryo; A Laboratory Manual, 2. ed., Cold Spring Harbor Press (1999); Jackson et al., Mouse Genetics and Transgenics: A Practical Approach, Oxford University Press (2000); and Pinkert, Transgenic Animal Technology: A Laboratory Handbook, Academic Press (1999). In some embodiments, transgenic non-human living entities have a targeted disruption or replacement of the target construct encoding the given heavy chain and / or light chain. In a preferred embodiment, the transgenic living creatures contain and express nucleic acid molecules encoding heavy and light chains that specifically bind to ALK-1, preferably human ALK-1. In some embodiments, the transgenic living entities comprise nucleic acid molecules encoding the modified antibody, such as a single chain antibody, a chimeric antibody, or a humanized antibody. Antibodies against ALK-1 can be produced in any transgenic animal. In a preferred embodiment, the non-human living entities are mice, rats, sheep, pigs, goats, cattle or horses. A non-human transgenic living being expresses said encoded polypeptides in blood, milk, urine, saliva, tears, mucus and other body fluids.
Phage display libraries [0223] The disclosure provides a method of producing an anti-ALK-1 antibody or antigen-binding portion thereof comprising the steps of synthesizing a human antibody phage library, screening this library using ALK-1 or antigen-binding portion thereof, isolating the phage that binds ALK -1 and obtain antibody from this phage. By way of example, one method of producing an antibody library for use in phage display techniques includes the steps of immunizing a non-human animal containing human immunoglobulin loci using ALK-1 or its antigenic portion to elicit an immune response, extracting antibody producing cells from immunized living being, isolation of RNA encoding the heavy and light chains of antibodies of the invention from extracted cells, reverse transcribing RNA to generate cDNA, amplifying cDNA using primers, and inserting cDNA into a phage display vector so that the antibodies are expressed on that phage. In this way, recombinant anti-ALK-1 antibodies of the invention can be obtained.
[0224] Recombinant human anti-ALK-1 antibodies of the invention can be isolated by screening a recombinant combinatorial antibody library. Preferably, this library is a scFv phage display library generated using human VL and VH cDNA generated from mRNA isolated from B cells. Methods for producing and screening such libraries are known in the art. Sets for creating phage display libraries are commercially available (e.g. Pharmacia Recombinant Phage Antibody System, catalog numbers 27-9400-01; and presentation set on the Stratagene SurfZAP phage<sup>™</sup>, catalog number 240612). There are also other methods and reagents that can be used to generate and screen antibody display libraries (see, e.g., US Patent No. 5,223,409; PCT Publication No. WO 92/18619, WO 91/17271, WO 92/20791, WO 92/5679, WO 93/01288, WO 92/01047, WO 92/09690; Fuchs et al., Bio / Technology 9: 1370-1372 (1991); Hay et al., Hum. Antibod. Hybridomas 3: 81-85 (1992); Huse et al., Science 246: 1275-1281 (1989); McCafferty et al., Nature 348: 552-554 (1990); Griffiths et al., EMBO J. 12: 725-734 (1993); Hawkins et al., J. Mol. Biol. 226: 889-896 (1992); Clackson et al., Nature 352: 624-628 (1991); Gram et al., Proc. Natl. Acad. Sci. USA 89: 3576-3580 (1992); Garrad et al., Bio / Technology 9: 1373-1377 (1991); Hoogenboom et al., Nuc. Acid Res. 19: 4133-4137 (1991); and Barbas et al., Proc. Natl. Acad. Sci. USA 88: 7978-7982 (1991).
[0225] In one embodiment, to isolate and produce human anti-ALK1 antibodies with the desired properties, the human anti-ALK-1 antibody described herein is first used to select human heavy and light chain sequences with similar binding activity to ALK-1, using epitope imprinting methods described in PCT Publication No. WO 93/08213. The antibody libraries used in this method are preferably scFv libraries generated and screened as described in PCT Publication No. WO 92/01047, McCafferty et al., Nature 348: 552-554 (1990); and Griffiths et al., EMBO J. 12: 725-734 (1993). The scFv antibody libraries are preferably screened using human ALK-1 as the antigen.
[0226] After the initial selection of human VL and VH domains, "mixing and matching" experiments are performed in which different pairs of preselected VL and VH segments are screened for ALK-1 binding to select preferred combinations of VL / VH pairs. In addition, in order to further improve the quality of the antibody, the VL and VH segments of the preferred VL / VH pair (s) can be randomly mutated, preferably in the CDR3 region of VH and / or VL, by a process analogous to the in vivo somatic mutation process responsible for affinity maturation of antibodies during a natural immune response. This in vitro affinity maturation can be achieved by propagating the VH and VL domains using PCR primers complementary to CDR3 with VH or CDR3 with VL, respectively, which primers were "labeled" with a random mixture of four nucleotide bases at certain positions so that the resulting PCR products encode VH and VL segments into which random mutations were introduced in the VH and / or VL CDR3 regions. These randomly mutated VH and VL segments can be screened again for ALK-1 binding.
[0227] After screening and isolation of the anti-ALK-1 antibody of the invention from a recombinant immunoglobulin display library, the nucleic acids encoding the selected antibody can be recovered from the display kit (e.g., from the phage genome) and cloned into other expression vectors using standard recombination techniques GOUT. If desired, the nucleic acid may be further maipulated to create other forms of the antibody of the invention as described below. To express a recombinant human antibody isolated by screening a combinatorial library, DNA encoding the antibody is cloned into a recombinant expression vector and introduced into mammalian host cells as described above.
Deimmunized Antibodies [0228] In another aspect of the invention, the antibody may be deimmunized to reduce its immunogenicity using techniques described in, e.g., PCT Publication Nos. WO98 / 52976 and WO00 / 34317.
Mutant Antibodies [0229] In a further embodiment, the nucleic acid molecules, vectors and host cells can be used to produce mutated anti-ALK-1 antibodies. Antibodies can be mutated in the heavy and / or light chain variable domains e.g. to change the binding properties of the antibody. For example, the mutation may be introduced in one or more CDR regions to increase or decrease the KD of the ALK-1 antibody, to increase or decrease the koff, or to change the binding specificity of the antibody. Techniques of site-directed mutagenesis are well known in the art. See, e.g., Sambrook et al. and Ausubel et al., supra. In another embodiment, one or more mutations are introduced at an amino acid residue that is known to be altered compared to the germline in monoclonal antibody 1.11.1; 1.12.1; 1.12.1 (RWT); 1.12.1 (M29I / D19A); 1.12.1 (M29I); 1.12.1 (D19A); 1.13.1; 1.14.1; 1.151.1; 1.162.1; 1.183.1; 1.27.1; 1.29.1; 1.31.1; 1.8.1; 1.9.1; 4.10.1; 4.24.1; 4.38.1; 4.58.1; 4.62.1; 4.68.1; 4.72.1; 5.13.1; 5.34.1; 5.53.1; 5.56.1; 5.57.1 or 5.59.1. Mutations can be introduced in the CDR region or in the variable region framework region or in the constant domain. In a preferred embodiment, the mutations are introduced in the variable domain. In some embodiments, one or more mutations are introduced at an amino acid residue that is known to be altered compared to the germline in the CDR or framework region of the variable domain with the amino acid sequence of SEQ ID NO: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90 92 or 127, or whose nucleotide sequence is depicted in SEQ ID NO: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81, 83, 85, 87, 89, 91, 95, 102 or 126.
[0230] In another embodiment, the framework is mutated such that the obtained framework (s) have (have) an amino acid sequence corresponding to the germline gene sequence. The mutation can be introduced in the framework region or in the constant domain to increase the half-life of the anti-ALK-1 antibody. See, e.g., PCT Publication No. WO 00/09560. A mutation may also be introduced into the framework or constant domain to change the immunogenicity of the antibody, provide a site for covalent or non-covalent binding of another molecule, or change properties such as complement binding, FcR binding, and antibody dependent cellular cytotoxicity (ADCC). According to the invention, one antibody may contain mutations in any one or more of the CDRs or framework regions of the variable domain or in the constant domain.
[0231] In some embodiments, there are from 1 to 13, including any number in this range, of amino acid mutation in the VH or VL domains of the mutated anti-ALK-1 antibody compared to the anti-ALK-1 antibody before mutation. In any of the above, mutations may occur in one or more CDR regions. In addition, each of the mutations may be a conservative amino acid substitution. In some embodiments, there are no more than 5, 4, 3, 2 or 1 amino acid changes in the constant domains.
Modified Antibodies [0232] In a further embodiment, a fusion antibody or immunoadhesin may be prepared that comprises all or part of the anti-ALK-1 antibody of the invention fused to another polypeptide. In a preferred embodiment, only the variable domains of the anti-ALK-1 antibody are linked to the polypeptide. In another preferred embodiment, the VH domain of the anti-ALK-1 antibody is linked to the first polypeptide, while the VL domain of the anti-ALK-1 antibody is linked to the second polypeptide that interacts with the first polypeptide in such a way that these VH and VL domains can combine with each other interact to form an antigen binding site. In another preferred embodiment, the VH domain is separated from the VL domain by a linker, such that the VH and VL domains can interact with each other (see single chain antibodies below). The VH-linker-VL antibody is then linked to the given polypeptide. In addition, fusion antibodies can be prepared in which two (or more) single chain antibodies are linked to each other. This is useful when there is a need to produce a divalent or multivalent antibody on a single polypeptide chain or to produce a dual specificity antibody.
[0233] To produce a single chain antibody (scFv), DNA fragments encoding VH and VL are operably linked to another fragment encoding a flexible linker, e.g., encoding the amino acid (Gly4-Ser) 3 sequence, so that the VH and VL sequences can be expressed as continuous single chain protein, with VL and VH domains connected by a flexible linker. See, e.g., Bird et al., Science 242: 423-426 (1988); Huston et al., Proc. Natl. Acad. Sci. USA 85: 5879-5883 (1988); McCafferty et al., Nature 348: 552-554 (1990). A single chain antibody can be monovalent when only single VH and VL are used, divalent when two VH and VL are used, or multivalent when more than two VH and VL are used. Bispecific or multivalent antibodies can be generated that bind specifically to ALK-1 and to another molecule.
[0234] In other embodiments, other modified antibodies can be produced using nucleic acid molecules encoding anti-ALK-1 antibody. For example, "standard kappa bodies" (III et al., Protein Eng. 10: 949-57 (1997)), "mini-bodies" (Martin et al., EMBO J. 13: 5303-9) can be produced using standard molecular biology techniques. (1994)), "diabodies" (Holliger et al., Proc. Natl. Acad. Sci. USA 90: 6444-6448 (1993)) or "Januzine" (Traunecker et al., EMBO J. 10: 3655-3659 (1991) and Traunecker et al., Int. J. Cancer (Suppl.) 7: 51-52 (1992) as described in this specification.
[0235] Bispecific antibodies or antigen binding fragments can be produced by a variety of methods, including hybridoma fusion or combination of Fab 'fragments. See, e.g., Songsivilai and Lachmann, Clin. Exp. Immunol. 79: 315-321 (1990), Kostelny et al., J. Immunol. 148: 1547-1553 (1992). In addition, dual specificity antibodies can be formed in the form of "diabodies" or "janazines". In some embodiments, the dual specificity antibody binds to two different epitopes of ALK-1. In some embodiments, the dual specificity antibody has a first heavy chain and a first light chain monoclonal antibody 1.11.1; 1.12.1; 1.12.1 (RWT); 1.12.1 (M29I / D19A); 1.12.1 (M29I); 1.12.1 (D19A); 1.13.1; 1.14.1; 1.151.1; 1.162.1; 1.183.1; 1.27.1; 1.29.1; 1.31.1; 1.8.1; 1.9.1; 4.10.1; 4.24.1; 4.38.1; 4.58.1; 4.62.1; 4.68.1; 4.72.1; 5.13.1; 5.34.1; 5.53.1; 5.56.1; 5.57.1 or 5.59.1 and an additional heavy chain and light chain of antibody. In some embodiments, this additional heavy chain and light chain may also be in the form of one of the above-mentioned monoclonal antibodies, but is different from the first heavy and light chain.
[0236] In certain embodiments, the modified antibodies described above are produced using one or more variable domains or CDRs from the human anti-ALK-1 monoclonal antibody provided herein.
Derivatized and labeled antibodies [0237] The anti-ALK-1 antibody or antigen-binding portion of the invention can be derivatized or combined with another molecule (e.g., another peptide or protein). Generally, antibodies or parts thereof are derivatized so that derivatization or unpacking does not adversely affect ALK-1 binding. Accordingly, the antibodies and antibody portions of the invention are intended to include both intact and modified forms of the human anti-ALK-1 antibodies described herein. For example, an antibody or portion of an antibody of the invention can be operably linked (via chemical conjugation, genetic fusion, non-covalent binding or otherwise) to one or more other molecules, such as another antibody (e.g. dual specificity antibody or diabody), detection agent, pharmaceutical agent and / or protein or peptide that can mediate the binding of the antibody or antibody portion to another molecule (such as streptavidin core region or polyhistidine tag).
[0238] One type of derivatized antibody is produced by cross-linking two or more antibodies (of the same type or different types, e.g., to generate dual specificity antibodies). Suitable cross-linking agents include factors that are heterodifunctional, containing two separate reactive groups separated by a suitable spacer (e.g. m-maleimidobenzoyl-N-hydroxysuccinimide ester) or homodifunctional (e.g. disuccinimidyl subperate). Such linkers are available from Pierce Chemical Company, Rockford, II.
[0239] Another type of derivatized antibody is labeled antibody. Useful detection agents that can be derivatized with an antibody or antigen binding portion thereof of the invention include fluorescent compounds, including fluorescein, fluorescein isothiocyanate, rhodamine, 5-dimethylamino-1-naphthalenesulfonyl chloride, phycoerythrin, lanthanide phosphors and the like. The antibody can also be labeled with enzymes that are useful for detection, such as horseradish peroxidase, β-galactosidase, luciferase, alkaline phosphatase, glucose oxidase and the like. When an antibody is labeled with a detectable enzyme, it is detected by adding additional reagents that this enzyme uses to produce a reaction product that can be recognized. For example, when the agent horseradish peroxidase is present, the addition of hydrogen peroxide and diaminobenzidine leads to a colored reaction product that is detectable. The antibody can also be labeled with biotin and detected in indirect measurement of avidin or streptavidin binding. The antibody can also be labeled with a predetermined polypeptide epitope recognized by a secondary reporter (e.g. leucine zipper pair sequences, secondary antibody binding sites, metal binding domains, marker epitopes). In some embodiments, the tags are attached via spacer arms of varying lengths to reduce potential spatial hindrance.
[0240] The anti-ALK-1 antibody can also be derivatized with a chemical group such as polyethylene glycol (PEG), methyl or ethyl or carbohydrate. These groups are useful for improving the biological properties of an antibody, e.g., for extending serum half-life.
Pharmaceutical compositions and administration [0241] The invention also relates to a pharmaceutical composition for the treatment of conditions associated with undesirably increased angiogenesis in a mammal, including a human, comprising such an amount of an anti-ALK-1 antibody or antigen-binding portion thereof as described herein, which is effective in the treatment of such conditions, and a pharmaceutically acceptable carrier.
[0242] The antibodies and antigen binding portions of the present invention may be incorporated into a pharmaceutical composition suitable for administration to a subject. Typically, the pharmaceutical composition comprises an antibody or antigen binding portion thereof of the invention and a pharmaceutically acceptable carrier. As used herein, the term "pharmaceutically acceptable carrier" means any and all solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic and absorption delaying agents and the like that are physiologically compatible. Some examples of pharmaceutically acceptable carriers are water, saline, phosphate buffered saline, dextrose, glycerol, ethanol and the like, as well as combinations thereof. In many cases, it will be preferable to include isotonic agents, for example, sugars, polyalcohols such as mannitol, sorbitol or sodium chloride in the composition. Additional examples of pharmaceutically acceptable carriers are wetting agents or small amounts of excipients, such as wetting or emulsifying agents, preservatives or buffers, which increase the shelf life or effectiveness of the antibody.
[0243] The compositions of this invention may be in a variety of forms, for example liquid, semi-solid and solid dosage forms, such as liquid solutions (e.g., solutions for injection and infusion), dispersions or suspensions, tablets, pills, powders, liposomes and suppositories . The preferred form depends on the intended mode of administration and therapeutic application. Typical preferred compositions are in the form of solutions for injection or infusion, such as compositions similar to those used for passive immunization of humans. Parenteral (e.g. intravenous, subcutaneous, intraperitoneal, intramuscular) administration is the preferred method of administration. In a preferred embodiment, the antibody is administered by intravenous infusion or injection. In another preferred embodiment, the antibody is administered by intramuscular or subcutaneous injection. Formulations for injection may be presented in unit dosage form, e.g. in ampoules or multi-dose containers, with or without the addition of preservatives. The compositions may also be in the form of suspensions, solutions or emulsions in oily or aqueous vehicles, and may contain formulatory agents such as suspending, stabilizing and / or dispersing agents. Alternatively, the active substance may be in the form of a powder to be reconstituted in a suitable carrier, e.g. in sterile pyrogen-free water before use.
[0244] Therapeutic compositions typically must be sterile and stable under the conditions of manufacture and storage. The composition can be formulated as a solution, microemulsion, dispersion, liposome or other ordered structure suitable for high drug concentration. Sterile injectable solutions can be prepared by introducing the anti-ALK-1 antibody in the required amount in a suitable solvent with one of or a combination of the ingredients listed above as required, followed by sterilization by filtration. Generally, dispersions are prepared by incorporating the active substance into a sterile vehicle that contains the basic dispersion medium and the other required ingredients from those mentioned above. In the case of sterile powders for the preparation of sterile injectable solutions, preferred methods for their preparation are vacuum drying and lyophilization, which provide the powder with the active substance and any additional desired ingredient from its solution previously sterilized by filtration. The proper fluidity of the solution can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants. Prolonged absorption of the injectable compositions can be achieved by including in the composition an absorption delaying agent, e.g., monostearate and gelatin salts.
[0245] The antibodies or portions of the antibodies of the present invention can be administered in a variety of ways known in the art, but for many therapeutic applications, the preferred route / method of administration is subcutaneous, intramuscular or intravenous infusion. As will be appreciated by one of skill in the art, the route and / or method of administration will vary depending on the results desired.
[0246] In some embodiments, the antibody compositions of the present invention can be prepared with a carrier that will protect the antibody against rapid release, such as a controlled release formulation, including implants, transdermal patches, and microencapsulated delivery systems. Biodegradable biocompatible polymers may be used, such as vinyl acetate / ethylene, polyanhydrides, polyglycolic acid, collagen, polyorthoesters and poly lactic acid. Many methods for preparing such preparations are well known to those skilled in the art. See, e.g., Sustained and Controlled Release Drug Delivery Systems JR Robinson, ed., Marcel Dekker, Inc., New York, 1978.
[0247] Additional active compounds can also be incorporated into the composition. In some embodiments, the inhibitory anti-ALK-1 antibody of the invention is co-formulated and / or co-administered with one or more additional therapeutic agents. These agents include, but are not limited to, antibodies that bind to other target molecules, anti-cancer agents, anti-angiogenic agents, signal transduction inhibitors, antiproliferative agents, chemotherapeutic agents or peptide analogs that inhibit anti-ALK-1. Such combination therapies may require lower doses of the inhibitory anti-ALK-1 antibody as well as co-administered agents, avoiding possible toxicity or complications associated with various monotherapies. [0248] As noted above, the compositions of the present invention may optionally additionally contain a pharmaceutically acceptable antioxidant in addition to the chelating agent. Suitable antioxidants include, but are not limited to, methionine, sodium thiosulfate, catalase and platinum.
[0249] For example, the composition may contain methionine in a concentration that ranges from 1 mM to about 100 mM, especially about 27 mM. For example, the aqueous preparation may contain: 10 mg / ml anti-ALK-1 antibody, 20 mM histidine, pH 5.5, 84 mg / ml trehalose dihydrate, 0.2 mg / ml polysorbate 80, 0.05 mg / ml disodium salt EDTA, 0.1 mg / ml L-methionine.
[0250] The compositions of the invention may contain a "therapeutically effective amount" or "prophylactically effective amount" of an antibody or antigen binding portion of the invention. "Therapeutically effective amount" refers to the effective amount at the doses and periods of time necessary to achieve the desired therapeutic effect. The therapeutically effective amount of the antibody or antigen-binding portion may vary depending on factors such as disease stage, age, sex and body weight of the subject, and the ability of the antibody or antibody portion to elicit the desired response in the subject. A therapeutically effective amount is also the amount at which any toxic or harmful effects of the antibody or antigen-binding portion are overcome by the therapeutically beneficial effects. "Prophylactically effective amount" refers to the effective amount at the doses and periods of time necessary to achieve the desired preventive effect. Typically, because a prophylactic dose is used in patients before or at the onset of the disease, the prophylactically effective amount may be lower than the therapeutically effective amount.
[0251] Dosage regimens can be adjusted to provide the optimal response desired (e.g., a therapeutic or prophylactic response). For example, a single bolus may be administered, several divided doses over a period of time, or the dose may be proportionally reduced or increased as indicated by the requirements of the therapeutic situation. It is particularly preferred to formulate parenteral compositions in dosage unit form to facilitate administration and to harmonize the dose. Dosage unit forms as used herein refer to physically discrete units suitable as unitary dosages for the treated mammalian subjects; each unit containing a predetermined quantity of active compound calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. The specification for the unit dosage form of the invention is dictated by and directly dependent on (a) the unique characteristics of the anti-ALK-1 antibody or part thereof and the specific therapeutic or prophylactic effect to be achieved, and (b) the associated limitations in the art regarding the production of such antibodies for treating sensitivity in individuals. [0252] An exemplary, non-limiting therapeutic or prophylactic effective amount of an antibody or antibody portion according to the invention is 0.025 to 50 mg / kg, more preferably 0.1 to 50 mg / kg, more preferably 0.1-25, 0.1 to 10 or 0.1 to 3 mg / kg. In some embodiments, the formulation contains 5 mg / mL of antibody in 20 mM sodium citrate buffer, pH 5.5, 140 mM NaCl, and 0.2 mg / mL polysorbate 80. It should be noted that dose values may vary with the type and severity of the condition to be alleviated. It should also be understood that for any particular individual, specific administration modes should be adjusted over time according to the individual needs and professional judgment of the person administering or supervising the administration of the composition, and that the dose ranges provided herein are exemplary only and do not limit the scope or use of practice of proprietary composition.
[0253] A further aspect of the present invention provides kits comprising an anti-ALK-1 antibody or antigen binding portion of the invention, or a composition comprising such an antibody or portion. The kit may include, in addition to the antibody or composition, diagnostic or therapeutic agents. The kit may also contain instructions for use in a diagnostic or therapeutic method. In a preferred embodiment, the kit comprises an antibody or a composition containing it and a diagnostic agent that can be used in the method described below. In another preferred embodiment, the kit comprises an antibody or a composition containing it and one or more therapeutic agents that can be used in the method described below.
Diagnostic methods of use [0254] Anti-ALK-1 antibodies or antigen-binding portions thereof can be used in diagnostic methods for detecting ALK-1 in a biological sample in vitro or in vivo. For example, anti-ALK-1 antibodies can be used in traditional immunoassays including, but not limited to, ELISA, RIA, flow cytometry, tissue immunohistochemistry, Western blot, or immunoprecipitation. The anti-ALK-1 antibodies of the invention can be used to detect ALK-1 in humans. Antibodies against ALK-1 can also be used to detect ALK-1 in other primates, e.g. cynomolgus macaque.
[0255] The invention further provides a method of detecting ALK-1 in a biological sample, comprising contacting said biological sample with an anti-ALK-1 antibody of the invention and detecting bound antibody. In one embodiment, the anti-ALK-1 antibody is directly labeled with a detectable label. In another embodiment, the anti-ALK-1 antibody (first antibody) is not labeled, and the second antibody or other molecule that can bind to the anti-ALK-1 antibody is labeled. As is well known to those skilled in the art, the second antibody is selected to be able to specifically bind to a particular type and class of the first antibody. For example, when the anti-ALK-1 antibody is human IgG, then the secondary antibody may be an anti-human IgG antibody. Other molecules that can bind to antibodies include, but are not limited to, Protein A and Protein G, both of which are commercially available, e.g. from Pierce Chemical Co.
[0256] Suitable labels for the antibody or secondary antibody have previously been discussed and include various enzymes, prosthetic groups, fluorescent materials, luminescent materials and radioactive materials. Examples of suitable enzymes include horseradish peroxidase, alkaline phosphatase, β-galactosidase or acetylcholinesterase; examples of suitable prosthetic group complexes include streptavidin / biotin and avidin / biotin; examples of suitable fluorescent materials include umbeliferone, fluorescein, fluorescein isothiocyanate, rhodamine, dichlorotriazinylaminofluorescein, dansyl chloride or phycoerythrin; an example of luminescent material includes luminol; and examples of suitable radioactive materials include <sup>125</sup>AND, <sup>131</sup>AND, <sup>35</sup>Wedding <sup>3</sup>H.
[0257] In other embodiments, ALK-1 can be tested in a biological sample in a competition immunoassay using ALK-1 standards labeled with a detectable substance and unlabeled anti-ALK-1 antibody. In this test, the biological sample, labeled ALK-1 standards and anti-ALK-1 antibody are combined and the amount of labeled ALK-1 pattern associated with the unlabeled antibody is determined. The amount of ALK-1 in the biological sample is inversely proportional to the amount of labeled ALK-1 standard bound to the anti-ALK-1 antibody.
[0258] The immunoassays disclosed above can be used for a variety of purposes. For example, anti-ALK-1 antibodies can be used to detect ALK-1 in cultured cells. In a preferred embodiment, anti-ALK-1 antibodies are used to determine the amount of ALK-1 produced by cells that have been treated with various compounds. This method can be used to identify compounds that modulate ALK-1 protein levels. According to this method, one sample of cells is treated with the test compound for some time, while the other sample is left untreated. If total ALK-1 levels are to be measured, cells are lysed and total ALK-1 levels are measured using one of the immunoassays described above. The total ALK-1 level in the treated cells is compared to untreated cells to determine the effect of the test compound.
[0259] A preferred immunoassay for measuring total ALK1 levels is flow cytometry or immunohistochemistry. Methods such as ELISA, RIA, flow cytometry, Western blot, immunohistochemistry, labeling of membrane-integrated proteins on the surface of cells and immunoprecipitation are well known in the art. See, e.g., Harlow and Lane, above. In addition, immunoassays can be adapted for high throughput screening to test a large number of compounds for activation or inhibition of ALK-1 expression.
[0260] Anti-ALK-1 antibodies of the invention can also be used to determine ALK-1 levels in tissue or cells derived from that tissue. In some embodiments, the tissue is diseased tissue. In certain embodiments of this method, tissue or biopsy material is collected from a patient. The biopsy tissue or material is then used in an immunoassay to determine, e.g., total ALK-1 levels or ALK-1 localization by the methods discussed above.
[0261] Antibodies of the present invention can also be used in vivo to identify tissues and organs that express ALK-1. One of the benefits of using the human anti-ALK-1 antibodies of the present invention is that they can be safely used in vivo without eliciting a substantial immune response to this antibody after administration, as opposed to non-human or humanized or chimeric antibodies.
[0262] The method includes the steps of administering detectably labeled anti-ALK-1 antibodies or compositions containing them to a patient in need of such diagnostic testing and subjecting this patient to imaging analysis to determine the location of ALK-1 expressing tissues. Imaging analysis is well known in the medical field and includes, but is not limited to, X-ray analysis, magnetic resonance imaging (MRI) or computed tomography (CT).

The at least one additional therapeutic agent may also be administered separately or in a non-derivatized or unconjugated manner. When the at least one additional therapeutic agent is not derivatized or conjugated to the antibody, it may be administered in the same pharmaceutical formulation as the antibody, or may be administered as a separate formulation.
Treatment of vision loss [0337] The compounds of the invention and the pharmaceutical compositions containing them are useful for the treatment of acute vision loss due to age-related macular degeneration and other diseases affecting the posterior segment of the eye, such as choroidal neovascularization, diabetic retinopathy, glaucoma, and retinopathy similar.
[0338] For example, the compounds of the invention may be used to form a drug depot at the back of the eye and may include one or more pharmaceutically active agents in addition to one or more pharmaceutically inactive excipients as described herein. Examples of pharmaceutically active agents useful in the compositions of the invention include anti-infective agents including, but not limited to, antibiotics, anti-viral and anti-fungal agents; antiallergic agents and mast cell stabilizers; steroidal and nonsteroidal anti-inflammatory agents (such as nepafenac); cyclooxygenase inhibitors including, without limitation, Cox I and Cox II inhibitors; combinations of anti-infective and anti-inflammatory agents; decongestants, anti-glaucoma agents including, but not limited to, adrenergic drugs, beta-blockers, beta-adrenergic agonists, parasympathomimetic agents, cholinesterase inhibitors, carbonic anhydrase inhibitors and prostaglandins; combinations of anti-glaucoma agents; antioxidants; dietary supplements; drugs for the treatment of cystoid macular edema including, but not limited to, nonsteroidal anti-inflammatory drugs; medicines for the treatment of age-related macular degeneration (AMD), including non-exudative (dry) and exudative (wet) AMD, including but not limited to angiogenesis inhibitors, including angiogenesis inhibitors that inhibit protein kinase receptors, including kinase receptors protein like VEGF receptors; and dietary supplements; medications for the treatment of herpes and eye infections caused by CMV; drugs for the treatment of proliferative vitreoretinopathy, including without limitation antimetabolites and fibrinolytics; wound healing modulators including, without limitation, growth factors, antimetabolites, neuroprotective drugs, including without limitation eliprodil; and angiostatic steroids for the treatment of diseases or conditions of the posterior segment of the eye 26, including without limitation of age-related macular degeneration (AMD), including non-exudative (dry) and exudative (wet) AMD, choroidal neovascularization, retinopathy, retinitis, membrane inflammation angioedema, macular edema and glaucoma. For additional information on such angiostatic steroids, see US Patent Nos. 5,679,666 and 5,770,592. Nepafenac is a nonsteroidal anti-inflammatory drug for the treatment of cystoid macular edema.
[0339] When administered to the eye, the compound of the present invention is provided in a pharmaceutically acceptable ophthalmic carrier such that the compound is kept in contact with the surface of the eye for a time sufficient to allow the compound to penetrate through the cornea and / or sclera and internally parts of the eye, including, for example, the anterior chamber, posterior chamber, vitreous humor, aqueous humor, vitreous humor, iris / ciliary body, lens, choroid / retina and sclera. The pharmaceutically acceptable ophthalmic carrier may be an ointment, vegetable oil or encapsulation material. The compound of the invention may also be injected directly into the vitreous or aqueous humor.
[0340] In addition, the compound can also be administered by well-known methods such as Tenon capsule injections and / or subconjunctival injections. As is well known in the field of ophthalmology, the macula consists primarily of retinal suppositories and is the area of maximum visual acuity on the retina. Tenon's purse or Tenon's membrane lies on the sclera. The conjunctiva covers a short segment of the posterior part of the eye to the limbus (conjunctival of the eyeball) and wraps up (upper conjunctival sac) or down (lower conjunctival sac) covering the inner areas of the upper eyelid or lower eyelid, respectively. The conjunction is on Tenon's purse. Tenon's sclera and capsule form the outer surface of the eyeball. For the treatment of eye diseases such as age-related macular degeneration (AMD), including exudative (dry) and exudative (wet) AMD, choroidal neovascularization, retinopathies (such as diabetic retinopathy, premature retinopathy), diabetic macular edema, inflammation retinitis, uveitis, cystoid macular edema (CME), glaucoma and other diseases or conditions of the back of the eye, it is preferable to apply a depot to a specific amount of the ophthalmically acceptable pharmaceutically active agent directly on the outer surface of the sclera and under the Tenon capsule. In addition, in cases of age-related macular degeneration (AMD), including non-exudative (dry) and exudative (wet) AMD and CME, it is best to apply the depot directly to the outer surface of the sclera, under the Tenon capsule, and generally above the macula.
[0341] The compounds may be formulated as depot preparations. Such long acting preparations can be administered by implantation (e.g. subcutaneous or intramuscular), intramuscular injection or the aforementioned injection under the Tenon capsule or intravitreal. Alternatively, the active ingredient may be in the form of a powder to be reconstituted prior to use in a suitable vehicle, e.g., sterile pyrogen-free water.
[0342] In particularly preferred embodiments of the invention, the compounds may be prepared for topical administration in physiological saline (combined with any preservatives and antimicrobial agents commonly used in eye preparations) and administered as eye drops. The solution or suspension can be prepared in pure form and administered several times a day. Alternatively, the present compositions, prepared as described above, can also be administered directly into the cornea.
[0343] In preferred embodiments, the composition is prepared using a mucoadhesive polymer that binds to the cornea. Thus, for example, the compounds may be formulated using appropriate polymeric or hydrophobic materials (e.g. in the form of an emulsion in a pharmaceutically acceptable oil) or ion exchange resins or in the form of sparingly soluble derivatives, e.g. sparingly soluble salts.
[0344] The pharmaceutical carrier for hydrophobic compounds is a co-solvent system comprising benzyl alcohol, a non-polar surfactant, a water-miscible organic polymer and an aqueous phase. The cosolvent system may be a VPD cosolvent system. VPD is a 3% w / v solution benzyl alcohol, 8% w / v non-polar surfactant polysorbate 80 and 65% w / v polyethylene glycol 300, made up to volume with anhydrous ethanol. The VPD co-solvent system (VPD: 5W) contains VPD diluted 1: 1 with a 5% dextrose in water solution. This cosolvent system dissolves hydrophobic compounds well and induces low toxicity after peripheral administration. Of course, the proportions of the cosolvent system can vary significantly without affecting its solubility and toxicity. In addition, the nature of the components of the cosolvent system may be different: for example, other low-toxicity non-polar surfactants may be used instead of polysorbate 80; the polyethylene glycol fraction may be different; other biocompatible polymers e.g. polyvinylpyrrolidone can replace polyethylene glycol and other sugars or polysaccharides can be replaced by dextrose.
[0345] Alternatively, other delivery systems for hydrophobic pharmaceutical compounds can be used. Liposomes and emulsions are known examples of carriers or excipients for the administration of hydrophobic drugs. Certain organic solvents such as dimethyl sulfoxide may also be used, although usually at the cost of greater toxicity. In addition, the compounds may be delivered using a sustained release system, such as semipermeable matrices of solid hydrophobic polymers containing the therapeutic agent. Various sustained release systems have been developed and are known to those skilled in the art. Sustained-release capsules may, depending on their chemical properties, release the compounds for several weeks or even more than 100 days. Depending on the chemical properties and biological stability of the therapeutic agent, additional strategies for protein stabilization may be employed.
[0346] The pharmaceutical compositions may also contain suitable solid or gel phase carriers or excipients. Examples of such carriers or excipients include calcium carbonate, calcium phosphate, sugars, starches, cellulose derivatives, gelatin and polymers such as polyethylene glycols.
[0347] Each composition may be formulated for administration to a subject. The subject of the present invention is preferably a mammal, or more preferably a human.

[0351] Pharmaceutical compositions can be formulated by standard techniques using one or more suitable carriers, excipients and diluents. See, e.g., Remington's Pharmaceutical Sciences, (19 Ed. Williams and Wilkins, 1995). [0352] Formulations suitable for parenteral administration include aqueous and non-aqueous preparations isotonic with the blood of the intended recipient; and aqueous and non-aqueous sterile suspensions which may include suspension systems designed to direct the compound to blood components or to one or more organs. The formulations may be provided in closed containers with single or multiple doses, for example ampoules or vials. For ocular preparations, unit doses are preferred because there are no preservatives in the formulation. Other parenteral formulations may use preservatives that allow the use of multiple dose containers.
[0353] Solutions and suspensions may be prepared for immediate injection from sterile powders. Parenteral and intravenous forms may also contain minerals and other materials to suit the type of injection or delivery system chosen. [0354] Particular methods of parenteral administration contemplated by the present invention include ocular and intravitreal administration. Pharmaceutical preparations for ocular and intravitreal administration include phosphate buffered saline (PBS) and balanced isotonic saline (BSS) with or without excipients such as manitol or sorbitol as protein stabilizers.
[0355] Suitable carriers for parenteral solutions are usually water, a suitable oil, saline, aqueous dextrose (glucose) solution or similar sugar solutions and glycols such as polypropylene glycol or polyethylene glycols. Solutions for parenteral administration preferably contain a water-soluble salt of the active ingredient, suitable stabilizing agents and, if necessary, buffering substances. Antioxidants such as sodium bisulfite, sodium sulfite or ascorbic acid, alone or in combination, are suitable stabilizing agents. Citric acid salts or sodium EDTA are also used. In addition, parenteral solutions may contain preservatives such as benzalkonium chloride, methyl or propylparaben or chlorobutanol.

Determining an effective amount is within the skill of those in the art, particularly in light of the present disclosure.
[0373] Preferably, an effective amount of the active ingredient, e.g. anti-ALK-1 antibody is from about 0.0001 mg to about 500 mg of active agent per kilogram of patient weight, more preferably from about 0.001 to about 250 mg of active agent per kilogram of patient weight, even more preferably from about 0.01 mg to about 100 mg of active agent per kilogram of patient weight, more preferably from about 0.5 mg to about 50 mg of active agent per kilogram of patient weight, and most preferably from about 1 mg to about 15 mg of active agent per kilogram of patient weight.
[0374] In terms of the percentages given, the formulations of the present invention will preferably contain active agent, e.g., anti-ALK-1 antibody in an amount of from about 0.0001 to about 10% by weight, more preferably from about 0.001 to about 1% by weight, more preferably from about 0.05 to about 1% by weight, or more preferably from about 0.1% by weight up to about 0.5 wt.
Gene therapy [0375] Nucleic acid molecules that encode the antibodies or antibody portions of the present invention can be administered to a patient in need thereof by gene therapy. Therapy can be carried out in vivo or ex vivo. In a preferred embodiment, the patient is administered nucleic acid molecules encoding both heavy chain and light chain. In a more preferred embodiment, the nucleic acid molecules are administered in such a way that they are permanently integrated into the B lymphocyte chromosome, since these cells are specialized in the production of antibodies. In a preferred embodiment, B lymphocyte precursors are transfected or infected ex vivo, and then re-implanted in a patient in need. In a further embodiment, B-cell precursors or other cells are infected in vivo with a virus that is known to infect an interesting cell type. Typical vectors used for gene therapy include liposomes, plasmids and viral vectors. Exemplary viral vectors are retroviruses, adenoviruses and adeno-associated viruses. After infection in vivo or ex vivo, the level of antibody expression can be monitored by taking samples from the treated patient using any immunoassay known in the art or discussed herein.
[0376] In a preferred embodiment, the gene therapy method comprises the steps of administering an isolated nucleic acid molecule encoding the heavy chain or antigen-binding portion thereof of an anti-ALK-1 antibody and expressing that nucleic acid molecule. In another embodiment, the gene therapy method comprises the steps of administering an isolated nucleic acid molecule encoding the light chain or antigen-binding portion thereof of an anti-ALK-1 antibody and expressing that nucleic acid molecule. In a more preferred method, the gene therapy method comprises the steps of administering an isolated nucleic acid molecule encoding a heavy chain or antigen binding portion thereof and an isolated nucleic acid molecule encoding a light chain or antigen binding portion thereof against an ALK-1 antibody and expressing these nucleic acid molecules. The gene therapy method may also include the step of administering another therapeutic agent, such as any of the agents discussed previously in connection with the combination therapy.
Method of searching for ALK-1 antagonists and agonists [0377] In one embodiment, the present disclosure provides a method of determining whether a substance inhibits regulation leading to stimulation of a specific downstream specific target gene for ALK-1, Id1, such as, for example, the Taqman Id1 test described in Example 12. This method involves contacting a sample of cells that express Id1 with this substance and determining whether Id1 expression has been inhibited, wherein the reduced level of Id1 expression in the sample of cells contacted with the substance compared to the control cell sample indicates that this substance inhibits expression Id1. In one particular case, the substance is an antibody that binds to the extracellular domain of ALK-1. Otherwise, the substance is a small molecule. According to the disclosure, cells can innate express both ALK-1 and Id1, such as the HUVEC cells described in Example 12, or may have been transformed or transfected using DNA encoding one or both of them. Id1 expression can be determined e.g. using the Taqman Id1 test described in Example 12.
[0378] Conversely, activators or agonists can also be tested and used according to the same procedures.

Example 1. Preparation of the ALK-1 immunogen [0381] ECD ALK-1 was cloned from the full-length human ORF clone for ALK-1 (Invitrogen, clone ID IOH21048) by PCR using a 5'ACGGCCCAGCCGGCCGACCCTGTGAAGCCGTCT (SEQ ID NO: 96) compatible primer and reverse 5'-ACTAAGCTTTTAATGATGATGATGATGATGCTGGCCATCTGTTCCCG (SEQ ID
NO: 97). The PCR product was purified, treated with SfiI and HindIII restriction enzymes, and cloned into the SfiI / HindIII site of the mammalian expression vector pSecTag2 / Hygro (Invitrogen Inc., Catalog No. V910-20). The clone was used for transient transfection of 293T cells using Fugene 6 transfection reagent (Roche Applied Science, Catalog No. 1814443) according to the manufacturer's instructions. The cell culture supernatant containing the secreted target protein was harvested 72 hours after transfection and allowed to bind to Ni-NTA resin (QIAGEN, Catalog No. 30430) at 4 ° C overnight. The resin was then washed with buffer containing 20 mM Tris pH 8.0, 25 mM imidazole and 300 mM sodium chloride. The His-Tag protein was eluted from the resin using a buffer containing 20 mM Tris pH 8.0, 300 mM imidazole and 300 mM sodium chloride. CM Sepharose cation exchange resin was used to further purify the protein in 20 mM sodium phosphate (pH 7.0) and the unbound fraction containing the target protein was collected. The buffer was exchanged for PBS or 10 mM HEPES, pH 7.4, plus 150 mM sodium chloride by dialysis and the protein was concentrated to 0.2-1 mg / ml with a final purity> 90%, assessed on Coomassie blue stained SDS PAGE gel. His-Tag ECD ALK-1 protein was strongly glycosylated at an observed MW of 26 KDa, compared to 11 KDa of the theoretical MW of this protein. His-Tag ECD ALK-1 protein (SEQ ID NO: 98) was used to generate hybridomas producing anti-ALK-1 antibody as described in Example 2.

Example 2. Production of hybridomas producing anti-ALK-1 antibody [0382] Eight to ten week old XENOMOUSE® mice were immunized with 10 μg hind paw pads / recombinant human ALK-1 / Fc chimera mouse (R&D Systems, Inc., catalog number 370 -AL) or the ECD ALK-1 protein from His-Tag described in Example 1. This dose was repeated five to seven times over a period of three to five weeks. Three or four days before the fusion, mice were given the last injection of immunogen in PBS. Lymphocytes from lymph nodes of immunized mice were fused to the non-secretory myeloma cell line P3-X63-Ag8.653 by cell electrophusion (ATCC Cat. No. CRL 1580), and these combined cells were subjected to HA-DMEM selection as previously described (DMEM / 15 % FBS / 1% 200 mM L-glutamine / 1% 100X no essential amino acid / 1% 100X Pen / Strep / 10 U / ml IL-6/1 vial / liter OPI medium supplemented with 0.5x HA (Azaserin-Hypoxanthine, Sigma, catalog number A9666)). A set of hybridomas were recovered, all of which secreted ALK-1 specific human IgG2 antibodies. [0383] An ELISA assay was used to detect antibody binding. Immunogen was coated on an Immulon 96 well microtiter plate (NUNCTM TM plate)
Immuno<sup>™</sup> with MaxiSorp surface<sup>™</sup>, Nalge Nunc International, Cat # 439454) at 4 μg / ml in 50 mM sodium bicarbonate buffer overnight at 4 ° C. Plates were washed and then blocked with PBS containing 0.1% Tween-20 and 0.5% bovine serum albumin. Antibodies were added to blocked ELISA plates, incubated for one hour and washed with PBS with Tween-20. Binding was detected using anti-human IgG-horseradish peroxidase antibodies (Pierce, catalog number 31420) followed by the addition of ABTS (Pierce, catalog number 37615). Colorimetric measurements were carried out at 405 nm using a microplate reader (SpectraMax Plus 384, Molecular Devices).
[0384] Twenty-five hybridomas were selected for further study. They were cloned into individual cells by limiting dilutions and designated 1.11.1; 1.12.1; 1.12.1 (RWT); 1.12.1 (M29I / D19A); 1.12.1 (M29I); 1.12.1 (D19A); 1.13.1; 1.14.1; 1.151.1; 1.162.1; 1.183.1; 1.27.1; 1.29.1; 1.31.1; 1.8.1; 1.9.1; 4.10.1; 4.24.1; 4.38.1; 4.58.1; 4.62.1; 4.68.1; 4.72.1; 5.13.1; 5.34.1; 5.53.1; 5.56.1; 5.57.1 and 5.59.1.
[0385] The murine hybrid cell line LN 15916 (hybridoma 1.12.1) was deposited under the conditions of the Budapest Treaty at the American Cell Culture Collection (ATCC), 10801 University Blvd., Manassas, VA 20110-2209 on June 21, 2005. Hybridomas 1.12. 1 is assigned the following access number PTA-6808. Example 3. Anti-ALK-1 antibody sequences [0386] To analyze the structure of the antibodies produced according to the invention, the nucleic acids encoding heavy and light chain fragments were cloned from hybridomas producing anti-ALK-1 monoclonal antibodies. Cloning and sequencing were carried out by standard methods.
[0387] Poly (A)<sup>+</sup> mRNA was isolated using a Fast-Track kit<sup>™</sup> (Invitrogen) of about 2 X 10<sup>5</sup> hybridoma cells for each ALK-1 antibody. CDNA was synthesized from mRNA using random primers. This cDNA obtained using random primers was amplified by PCR using primers specific for variable domains from the human VH or Vk family in combination with primers specific for the human Cy2 constant region or the Ck constant region to amplify the variable region of the antibody encompassing all framework regions (FR ) and complementarity determining regions (CDRs). Nucleic acid sequences encoding human kappa heavy and light chain transcripts from hybridomas producing anti-ALK-1 antibodies were obtained by direct sequencing of both strands of PCR products. Sequences were analyzed using proprietary Abgenix software and publicly available information about the sequence of human VH and Vk genes, "V BASE sequence directory", Tomlinson et al., MRC Center for Protein Engineering, Cambridge, UK). Identical results could be obtained using publicly available sequence alignment software by a specialist in the field using MacVector and Geneworks. [0388] In particular, the full-length anti-ALK-1 1.12.1 antibody was cloned into expression vectors as follows: Poly (A)<sup>+</sup> mRNA was isolated using the RNeasy Mini Kit (Qiagen) and cDNA was synthesized from mRNA using the Advantage RT-for-PCR kit (BD Biosciences) using oligo primers (dT). cDNA for the clone
1.12.1 obtained using oligo (dT) primers were propagated using the primers listed in Table 2. Amplification was carried out using Pfu Ultra polymerase (Stratagene) and PTC-200 DNA Engine (MJ Research) in the following cycles: 3 'at 95 ° C; 25x (20 "at 95 ° C, 30" at 52 ° C, 1'20 "at 72 ° C); 10 'at 72 ° C. Clone sequences were confirmed using Grills 16<sup>th</sup> BDTv3.1 / dGTP (Applied Biosystems Inc.) and 3730xl DNA analyzer (Applied Biosystems Inc.). In the VH 1.12.1 cloning process, a silent mutation in the eighth codon transforming "GGC" into "GGT" was introduced. All sequences were analyzed by alignment with "V BASE sequence directory" (Tomlinson, et al, J. Mol. Biol., 227, 776-798 (1992); Hum. Mol. Genet., 3, 853-860 (1994); EMBO J., 14, 4628-4638 (1995).)

[0391] Nucleic acid molecules encoding the heavy chain variable domain (SEQ ID NO: 5) and the light chain variable domain (SEQ ID: 7) of antibody 1.12.1 (M29I / D19A) were deposited under the terms of the Budapest Treaty in the American Breeding Collection Cell (ATCC), 10801 University Blvd., Ma5 nassas, VA 20110-2209 on July 14, 2005. Deposits were assigned the following access numbers: ATCC No. PTA-6864 for E. coli DH5a containing plasmid pCR2.1 TOPO
1.12.1 V<sub>H</sub> (M29I): UC 25502; and ATCC No. PTA-6865 for E. coli DH5a containing plasmid pCR2.1 TOPO 1.12.1 Vk (D19A): UC 25503.
[0392] Several specific human anti-ALK-1 antibodies shared a common pattern in the heavy chain variable domain CDR1. These lead molecules use segments 4-31 or 4-61 of the heavy chain V gene. The FR1 and CDR1 sequences corresponding to these heavy antibody chains are shown in Table 4A, aligned with the germline sequence. The dash (-) in the alignment means the residue identical to the germline. In all cases, the GYYWS pattern (SEQ ID NO: 136) at the end
CDR1 underwent somatic mutations giving a new sequence pattern in which the G residue is exchanged for the acid residue (D or E) and the final S residue is exchanged for N in 9 out of 12 examples. Sequence diversity in other VH regions indicates that these are probably independent somatic mutation events leading to the same sequence pattern at the VH CDR1 end.

Example 5. Preparation of Fab 1.12.1 molecules [0393] The Fab fragment of 1.12.1 (M29I / D19A) was prepared by digestion with IgG1 1.12.1 (M29I / D19A) using papain. Full length IgG1 1.12.1 (M29I / D19A) purified on Protein A was incubated with papain (VWR) in a ratio of 1:50 (papain: protein) in a buffer containing 30 mM sodium phosphate (pH 7.0), 2 mM EDTA and 2 mM cysteine at 37 ° C for 2-3 hours. The digested mixture was then loaded onto a mini76 Protein A column to remove undigested full length protein and Fc fragment. Unbound Fab was collected in the leak. A particle size size exclusion chromatography column (Superdex 200, Amersham Pharmacia Biotech) was then used to further purify the Fab protein and to exchange the buffer with PBS. Endotoxin was removed by applying the protein solution to a Detoxi gel (PIERCE) and then to a Vivapure Mini Q ion exchange column (VivaScience). The protein was filtered using a 0.2 Pm syringe filter and endotoxin levels were tested using the LAL pyrogen kit (Cambrex). The finally purified protein had a concentration of 2-3 mg / ml, with an endotoxin level <0.1 EU / mg and a purity> 95%. The Fab 1.12.1 fragment (M29I / D19A) has a molecular weight of 47347 under non-reducing conditions as shown by electrospray mass spectrometry. Edman N-terminal sequencing analysis confirmed the N-terminal sequence of the light chain as EIVLTQSPG (SEQ ID NO: 113) and the heavy chain as QVQLQESG (SEQ ID NO: 114), respectively.
Example 6. Determination of avidity values for fully human monoclonal anti-ALK-1 antibodies by surface plasmon resonance (SPR) using BIACORE ™ [0394] Avidity measurements of purified anti-ALK-1 antibodies by<sub>™</sub> plasmon resonance imaging using the BIACORE 3000 device was performed as follows using the manufacturer's protocols.
[0395] For performing kinetic analysis, recombinant human ALK-1 / Fc fusion protein (hALK-1 / Fc) and cynomolgus ALK-1 / Fc fusion protein (cALK-1 / Fc) were immobilized on separate flow chambers on a CM5 BIAcore sensor chip using routine amine coupling. Surfaces were prepared using 10 mM acetate buffer, pH 5.0 as immobilization buffer, achieving protein densities of 300 and 150 RU for hALK-1 / Fc and cALK-1 / Fc fusion proteins, respectively. Inactivation of unreacted N-hydroxysuccinimide esters was carried out using 1 M ethanolamine hydrochloride, pH 8.5. Antibody samples were prepared in wash buffer at concentrations ranging from 0.125 to 2 nM (0 nM solution containing wash buffer alone was included as a zero reference). Samples were randomized and injected in duplicate for 10 minutes through all 4 flow chambers using HBS-EP (10 mM HEPES pH 7.4, 150 mM NaCl, 3 mM EDTA, 0.005% Surfactant P20) as wash buffer. The observed association rates were independent of the flow rate from 1 to 100 gl / min, indicating no restrictions on transported masses. A flow rate of 25 μl / min was used to determine the avidity value. Dissociation of antibodies was monitored for 10 minutes, the surface was regenerated by a 12 second injection of 100 mM H<sub>3</sub>AFTER<sub>4</sub> (25 μl / min). The raw data was processed using the Scrubber software package (© BioLogic Software) and analyzed using the CLAMP software package (© BioLogic Software). Multiple data sets from a single surface, six data sets at a time, were simultaneously globally fitted to a simple 1: 1 Langmuir binding model using the common value of the variable Rmax. Table 5 lists the avidity values for exemplary anti-ALK-1 antibodies of the present invention. The data presented indicate that the antibodies produced according to the invention have high affinities and strong binding constants for human ALK-1.

Example 9. Determination of epitope selectivity of anti-ALK-1 antibodies [0400] Cross-competition testing was performed using a device <sub>™</sub>
BIACORE<sup>™</sup> 3000 (Biacore International AB, Uppsala, Sweden and Piscataway, NJ), according to the manufacturer's protocols.
[0401] The recombinant human ALK-1 / FC chimera was immobilized on a dextran layer on a CM5 biosensor chip using amine coupling. The chips were prepared using 10 mM acetate buffer, pH 5.0 as immobilization buffer, achieving 940 RU protein densities. Deactivation of unreacted N-hydroxysuccinimide esters was carried out using 1 M ethanolamine hydrochloride, pH 8.5.
[0402] The purified mAb was diluted to a concentration of 50 nM in HBS-EP wash buffer (0.01 M HEPES pH 7.4, 0.15 M NaCl, 3 mM EDTA, 0.005% Polysorbate 20). The primary antibody was selected and then injected through the flow chamber for 60 seconds at a rate of 10 g / min. After the injection was completed, a second antibody was selected and injected through the same flow chamber for 600 seconds at a rate of 10 μl / min. The sensor surface was regenerated by injecting 100 mM H for 12 seconds<sub>3</sub>AFTER<sub>4</sub> (25 μl / min).
[0403] After regeneration, the primary antibody was re-injected through the flow chamber for 600 seconds at a rate of 10 Pl / min. After the injection was completed, the secondary antibody was selected and injected through the same flow chamber for 600 seconds at a rate of 10 μl / min. After using the whole set of 14 antibodies as secondary antibodies, a new primary antibody was selected and the procedure with the new primary antibody was repeated. These procedures were carried out until all possible combinations of primary and secondary antibodies were injected through the flow cell. Secondary antibody binding was considered to have occurred if the total response observed after injection of both antibodies exceeded that observed for both possible thresholds. Threshold values were determined using the same antibody as the primary and secondary antibody. Table 8 shows a response matrix based on observed binding: - no binding of secondary antibody, x means binding was observed (response was higher than single antibody thresholds). Grouping of clones that showed the same activity patterns provides two different epitope drawers with 1.11.1 in one drawer and all other antibodies in the other drawer.

Example 10. Isolation of cynomolgus ALK-1 gene [0404] The cynomolgus ALK-1 gene ("Cyno") was taken from Cyno lung tissue. Based on the published gene sequence for human ALK-1 (register in Genebank L17075), primers for full-length ALK-1 cynomolgus PCR amplification were designed. mRNA was prepared from frozen cynomolgus lung tissue (approximately 1 g) using the mRNA purification kit (Ambion, Catalog No. 1915) according to the manufacturer's instructions. 200 ng mRNA was reverse transcribed and amplified by PCR using the OneStep RT-PCR kit (Qiagen, Catalog No. 210210) using gene specific oligo: 5'AGCGGGCCCAGAGGGACC / 1 TG (Seq ID NO: 115) (compliant) and 5'CAGAAAGGAATCAGGGCT Seq ID NO: 116) (reverse) at a connection temperature of 61 ° C. The appropriate size RT-PCR product (-1.5 Kb) was excised and purified from 0.9% agarose gel after electrophoresis, then TOPO-TA was cloned into the pCR4-TOPO vector (Invitrogen, Catalog No. K4575-01). The insert was sequenced to obtain the ORF nucleotide sequence for ALK-1 cynomolgus macaque. The translated nucleotide sequence and predicted amino acid sequence are shown in SEQ ID NOs: 93 and 94, respectively. While the cytoplasmic part of the gene encodes identical protein sequences in Cyno and human, there are 5 amino acid differences and 1 amino acid difference in the transmembrane domain of the protein in the extracellular domain (ECD, which covers positions 22-118). The ECD sequence identity between human and Cyno is 94.8%. The ECD alignment of humans and primates is shown in Figure 2.
[0405] A pair of primers (compatible: 5'- GATTĄTGGCCTTGGGCTCCCCCAGGAAA (Seq ID NO: 117) and inverse: 5'- GGGCZTTTGAATCACTTTAGGCTTTCTGG Seq. IDT were used to amplify the full length of the cynomolgus ALK-1 gene by PCR.
Example 11. Determination of cell surface binding and cross hybridization traits for primates by flow cytometry (FACS) [0406] To create cell lines with ALK-1 overexpression that can be used to test binding affinity against ALK-1 using flow cytometry (FACS) , full length human ALK-1 genes, Tin and rat were cloned into pcDNA5 / FRTo TOPO vectors from Invitrogen (catalog number K6510-20) and transfected with 293 Flp-In T-Rex host cells (Invitrogen, catalog number R780-07). Selections were made using hygromycin to obtain terminal stable cell lines. Overexpression of the corresponding full-length ALK-1 proteins was obtained by induction with tetracycline (2 μg / ml) at 37 ° C / 5% CO<sub>2</sub> for 24 hours.
[0407] Anti-ALK-1 mAbs were tested for their binding affinity to ALK-1 on the cell surface using the FACS assay using 293 stable cells overexpressing ALK-1 proteins. Cells were separated using trypsin-EDTA and washed with changed PBS-SA. After portioning into 96 well plates, cells were blocked with serum and incubated with various concentrations of specific mAb for one hour at 4 ° C. The cells were then washed and incubated with an anti-human κ secondary antibody conjugated to an R-PE phosphor prior to analysis using a FACSCalibur flow cytometer (BD Biosciences). 10,000 events were collected for each sample without any gates. Table 9 shows the geometric mean from the histogram for each sample plotted as a function of mAb concentration and the KD for each mAb calculated after fitting in a two-stage equilibrium model. Examples of equivalent FACS experiments for humans and primates are shown in Figure 3.

Example 14. Properties of internalization of anti-ALK-1 monoclonal antibodies [0415] FACS was used to monitor the temporal course of surface remaining on the ALK-1 receptor cell as well as the neutralizing antibody. ALK1 remaining on the cell surface is monitored using a marker antibody that is capable of binding to ALK-1 on the cell surface, however recognizing a different epitope than the neutralizing antibody. Mouse anti-human ALK-1 ECD mAb (R&D sytems, catalog number AF310) was identified and used as a marker antibody in the study.
[0416] The time course of internalization was studied using an endothelial cell line
HUVEC and HUAEC. Cells were cultured at 37 ° C and 5% CO 2 in 24 well plates containing 200 μl complete culture medium per well. At each of 11 time points over 48 hours, 2 μl of a 1 mg / ml antibody solution was added to one well and mixed (final neutralizing antibody concentration is 10 μg / ml). The plate is then placed back in a 37 ° C incubator up to the 0 o'clock time point when the plate is placed on ice to stop the internalization process. At this point, marker antibody (up to a final concentration of 10 μg / ml) was added to the wells and incubated on ice for one hour. The cells were then washed with PBS, separated by trypsinization and transferred to a 96 well plate. Cells were then washed, blocked and treated with secondary antibodies carrying various phosphors to depict both neutralizing antibody and receptor ALK-1 remaining on the cell surface. Samples were evaluated using a FACSCalibur flow cytometer, counting 3000-5000 events / sample. The geometric mean of each sample in the specified fluorescence channel was calculated and plotted as a function of time. The data was fitted to the modified radioactive decay equation to obtain the half-life (t1 / 2) of internalization as well as the percentage of neutralizing antibody or ALK-1 receptor remaining on the cell surface after the internalization stabilized. As shown in Figure 6, mAb 1.12.1 (M29I / D19A) is internalized at the same rate and to the same extent as the ALK-1 receptor from the cell surface. The half-life of internalization 1.12.1 (M29I / D19A) is ~ 2 hours. Equilibrium was reached when 50% of the antibody was internalized. A polyclonal antibody purchased from R&D systems (catalog number AF370) internalizes at t1 / 2 equal to one hour and achieves stabilization at internalization of ~ 70% of the receptor (Figure 6). Similar internalization properties were observed for other human anti-ALK-1 mAbs of the invention (not shown).
Example 15. Development of SCID mice with human foreskin [0417] The surgical procedure previously published by HC Yan, et al. Has been significantly modified. "Human / Severe Combined Immunodeficient Mouse Chimeras, An Experimental In Vivo Model System to Study the Regulation of Human Endothelial CellLeukocyte Adhesion Molecules", J. Clin. Invest 91: 986, 1993; J. Vamer "Regulation of Angiogenesis in Vivo by Ligation of Integrin a5b1 with the Central Cell-Binding Domain of Fibronectin" Amer. J. Path. 156 (4): 1345, 2000; K. Tahtis, et al. "Expression and Targeting of Human Fibroblast Activation Protein in a Human Skin / Severe Combined Immunodeficient Mouse Breast Cancer Xenograft Model" Mol. Cancer. Ther. 2 (8): 729, 2003. After arriving from the National Disease Research Institute and Cooperative Human Tissue Network, fragments of the human foreskin were cut off unhealthy areas and transferred to RPMI media (Cellgro / Mediatech, cat. Number MT-15-040-CV supplemented with penicillin and streptomycin (Gibco / Life Tech No. 15070-063) (add 5 ml pen / strep stock solution to 500 ml RPMI). Using a scalpel and cutting on a Petri dish, the skin was trimmed to an oval shape about 8 x 13 mm in size, cleaned of blunt ends and connective tissue, and stored on wet ice before surgery. Appropriate volume (4 μl / gram animal) of 100 mg / ml ketamine solution (Ketaset<sup>TR</sup>, Fort Dodge Animal Health) / 1 mg / ml medetomidine (Pfizer Animal Health - Dormitor) was injected intraperitoneally in the abdomen of scid mice (i.e. at an angle of 45 °, under the skin, but not very deep inward). After dormancy, mice were introduced into the eye lubricant and ketoprofen (10 mg / kg, Fort Dodge Animal Health) was injected subcutaneously and the skin was shaved at the surgical site. The operational region was surgically removed three times with Clorahexiderm (Butler, Chclo-Scrub 40, cat. No. WAB20109) followed by alcohol in circular motions starting from the center of the surgical site and then outwards avoiding moving from a dirty area back to clean. Mice were transferred to the prepared surgical hood and placed on a water-heated base (Gaymar Industries, catalog number TP500 T / Pump), which was kept at 37 ° C. Mice were then anesthetized with isofluorane for the duration of the operation. Dorsal mice were covered with a surgical sheet with a notch revealing the surgical site. The mouse skin was lifted with forceps and an oval piece of skin tissue was cut off with one move using curved scissors. The right size human foreskin was placed on the mice. Human and mouse skin were sewn together using the Ethilon seam (Ethicon Cat. No. 697H.), Starting from the top of the oval, then down, then the furthest part from the right and left. More sutures were made in between to connect the tissues more tightly. Around 8 stitches were made around the skin at equal distances from each other. A sterile saline syringe was used during surgery to hydrate the skin / surgical wound of the mice when they became dry. Bandaid was not placed on ra87. A transparent wrap around the bandage is loose<sub>™</sub> clean wrapper (3M Tegaderm<sup>™</sup>). The wrapper was cut to such a size that it covered an area slightly wider than the Bandaid dressing. Mice were then given Atipamezol (50-100 gl, Pfizer Animal Health - Antisedan) and allowed to recover in a heated cage for 5 - 10 min. The dressing and bandage were removed after 7-10 days, and by day 15 most of the skin looked like a scab. Complete healing occurred between 21-28 days, after which the skins were ready to inoculate the cancer cells. Figure 8 shows an example of histological analysis (H and E staining) of a section of transplanted skin after surgery. The histological structure of transplanted skin closely resembles the features of human skin transplanted to mice described by Tahtis, et al. "Expression and Targeting of Human Fibroblast Activation Protein in a Human Skin / Severe Combined Immunodeficient Mouse Breast Cancer Xenograft Model: Mol. Cancer. Ther. 2 (8): 729, 2003. he: layer of human epidermis; hd: a layer of human dermis.
Example 16. Collagen model in the SCID mice with human foreskin [0418] Stock collagen I (Cat. No. 354236, Becten-Dickinson) was diluted to 4 mg / ml with 0.02 N acetic acid and kept on ice before implantation. Acid collagen solution (8 parts) was mixed with 10X M199 (Sigma, catalog number M9163) (1 part) and human plasma fibronectin (catalog number) 354008, Becten-Dickinson) to achieve a final Fn concentration of 90 gl / ml; NaOH (1.0 N) was added to bring the pH to ~ 7.2. The collagen / Fn mixture was kept on ice until use. The implantation mixture was prepared using the above collagen / Fn mixture with the addition of an angiogenesis inhibitor of interest and with or without the addition of human large vessel endothelial cells (HMVEC) (Cascade Biologics, cat. No. C-010-5C). HMVEC cells were prepared in the form of 6 x 10<sup>6</sup> cells / ml in PBS. 50-100 μl of implanted bourgeois were injected intradermally into the foreskin in a chimeric scid mouse. 7-14 days later collagen plugs were collected, embedded in OCT compound (cat. No. 4583, Sajura Finetek, CA) and immediately frozen for immunohistochemical analysis. The collagen plug in the foreskin was identified using the Trichrome kit (cat. No. KC1641, Mater Tech, CA) as the blue staining shown in Figure 9 (A). Human vessels were identified by staining of human P-CAM using anti-human CD-31 antibody (Clone 13.3, Vector Laboratories) (Figure 9 (B)). Table 12 summarizes the staining and quantification of human vessels in a collagen model in the SCID mouse human foreskin chimera.

Example 17. M24met tumor model in the SCID mouse human foreskin chimney [0419] Mice with an implant between 5-10 weeks after surgery were typically used in these studies. The M24met cell line has been described by Mueller and colleagues in "Tissue factor-initiated thrombin generation activates the signaling thrombin receptor on malignant melanoma cells", Cancer Research, 55 (8): 1629-32, 1995. The M24met cell suspension was prepared as follows: M24met cells with 80% confluency were washed, trypsin was synyzed with trypsin / EDTA (Gibco, cat # 25200-056) and harvested in PRMI medium (Cellgro / Mediatech, cat. MT-15- 040-CV) supplemented by 10%
FBS (Cellgro / Mediatech, catalog number AKD-11775) and 2 mM L-glutamine (Cellgro / Mediatech, catalog number 25-005-Cl). Cells were centrifuged at 600 rpm for 5 min, resuspended in sterile PBS. Cell counts were estimated using a Coulter Counter (Beckman Coulter, Model Z2). The cells were centrifuged at 600 rpm for 5 min and resuspended in a collagen mixture<sub>7</sub>
Fn (3 mg / ml) to obtain a 4x10 cell / ml suspension for implantation.
[0420] For inoculation 2x10<sup>6</sup> the above cells were injected (50 μl 4x10<sup>7</sup> cells / ml) intradermally to human skin of transplanted mice. On day 5-7 after implant, tumors will be palpable and the mice are randomly divided into control and experimental groups prior to dosing. The control group was defined in such a way that the animals do not receive any dose or receive a vehicle dose in which the anti-ALK-1 antibody or the isotype dose of the corresponding IgG2 anti-KLH human monoclonal antibody (Pfizer Inc) has been reconstituted. The experimental group was determined in such a way that the animals receive a dose of anti-ALK-1 antibody 1.12.1 (M29I / D19A).
Example 18. Double immunofluorescence (IF) staining of human and mouse CD-31 [0421] Frozen tissue sections were air dried and fixed at -20 ° C in acetone (Fisher, cat. No. A16S-4) for 10 min. The samples were air-dried again and washed in PBS three times for 5 min each. Samples were blocked in 5% rabbit serum (Vector Laboratories, catalog number S-5000) in PBS for 30 min at room temperature. The primary antibody mixture was prepared in 5% rabbit serum with anti-human CD-31 antibody (Santa Cruz, catalog number SC1505) and anti-mouse CD-31 (Pharmingen, Clone Mec1 3.3, catalog number 01951A) at a dilution of 1: 100 and 1: 150. The above antibody mixture was added to tissue samples for one hour at RT. Blocks were washed in PBS three times for 5 min each before incubation with the secondary antibody mixture for one hour at RT. A mixture of secondary antibodies was prepared in PBS / 0.05% Tween-20 (Sigma, catalog number P1379), rabbit anti-goat antibody from Texas Red (Jackson Labs, catalog number 305-075-003) and rabbit anti-rat antibody from FITC (Jackson Labs, cat. No. 312-095-003). Antibodies were diluted 1:50 when frozen antibodies were used or 1: 100 when fresh antibodies were used. Sections were washed again in PBS three times 5 min before embedding in Vectashield (Hard Set, DAPI embedding medium, Vector Lab, CA, catalog number H-1500). Sections were kept in the dark and 4 ° C until image analysis. Imaging analysis was performed using an Olympus BX60 fluorescence microscope and photos were taken using an Olympus microfire color digital camera. Pictures were taken from 3-5 hot spots / section, from one section / animal, from 4-7 animals / group and the areas of the vessels indicated by positive staining against human CD-31 were quantified by three people using Image Pro Plus v4.5 (MediaCyberneties). The pharmacodynamic endpoint (group average) was expressed as a percentage of inhibition of human CD-31 compared to the control group or as the total area of human vessels. Statistical significance was determined in the ANOVA test. Figure 10 shows and immunofluorescent human (red) and mouse (green) vessels in an M24met tumor in the chimeric human SCID mouse foreskin.
Example 19. Immunohistochemical staining (IHC) of human CD-31 [0422] Frozen tissue sections were air dried and fixed at -20 ° C in acetone for 10 min. The samples were air-dried again and washed in PBS twice for 5 min. Samples were incubated in 0.075% H2O2 / methanol (Fisher Cat. No. A433-4) for 15 min and washed in PBS three times for 5 min each. Samples were blocked in 5% rabbit serum / PBS for 30 min and coated with 1: 100 anti-human CD-31 antibody (Santa Cruz, cat. No. SC1505) in 5% rabbit serum for one hour at RT. Samples were washed in PBS twice for 5 min and coated with 1: 200 rabbit anti-goat antibody (Vector Labs, cat. No. BA-5000) in 5% rabbit serum for 35 min at RT. The sections were then washed in PBS twice for 5 min and freshly prepared streptavidin (Vector Labs, ABC Elite kit, cat. No. PK-6100) was added. Sections were again washed in PBS two times for 5 min and then developed in diaminobenzidine (DAB) (Vector Labs, catalog number SK-4100). Sections were washed in PBS twice for 5 min and then in Mayers hematoxylin (Sigma, cat. No. HHS-32) for 5 seconds. The samples were well rinsed in diH2O and immersed twice in a dilute (5 ml stock solution in 1L diH2O) ammonium hydroxide solution (Sigma, cat. No. A-6899) and washed again in diH2O. The samples were then dehydrated in 70%, 90% and then 100% alcohol (Harleco, catalog number 65347/85) after 1 minute each and finally in xylene (JT Baker, catalog number 516.09). Sections were embedded in Cytoseal 60 (Stephens Scientific, catalog no. 8310-4) and covered with coverslips for imaging analysis. Figure 11 shows an IHC image of human vessels (brown) from an M24met tumor in a human chimera SCID chimera.
Example 20. Therapeutic treatment with anti-ALK-1 antibody 1.12.1 (M29I / D19A) [0423] For treatment, dosing was done subcutaneously (sc) or intravenously (iv). Typically, one dose of 1.12.1 antibody (M29I / D19A) was administered in each study. A second dose of anti-ALK-1 antibody, if necessary, was administered at 9 or
10. day. Multiple dose levels, e.g. 1, 5, 10, 50 mg / kg, have sometimes been administered to test the dose-dependent inhibition of human vascular growth. Animals were monitored daily and tumors were measured three times / week using a caliper. By day 14-17 tumors had a size between 250-350 mm<sup>3</sup> and were removed from the mice, embedded in OCT and frozen for IF or IHC analysis. Figure 12 shows exemplary immunofluorescent images of human (red) and mouse (green) vessels in control and treated with 1.12.1 (M29I / D19A) (10 mg / kg) M24met tumors in a human foreskin scid chimera. Dose-dependent inhibition of human tumor vessel growth by 1.12.1 (M29I / D19A) in the human foreskin SCID chimera model is shown in Figure 13 and a summary of related studies is shown in Table 13.

Example 21. Determination of EC50 in vivo [0424] Chimerom SCRE mice with human foreskin were intradermally implanted with M24met cells and treated (sc) with anti-ALK-1 1.12.1 antibody (M29I / D19A) at 1, 3, 5, 7.5, 10 and 50 mg / kg or isotype matched anti-human KLH antibody (10 mg / kg). As a result of the experiment, the area of human vessels in each tumor was quantified as described above. Anti-antibody concentrations
ALK-1 1.12.1 (M29I / D19A) in mouse plasma was measured using the following method: serum samples from mice were analyzed for the concentration of anti-ALK-1 1.12.1 antibody (M29I / D19A) by ELISA (enzyme-linked immunosorbent assay). ELISA plates were coated with 10 µg / ml goat specific anti-human IgG Fc antibody (Pierce, cat. No.
31123) in PBS, incubated overnight at 4 ° C and then blocked with blocking buffer
StartBlock.
[0425] (Pierce, cat. No. 37542) at room temperature for an hour. Serum samples were diluted 100 and 1000-fold in StartBlock blocking buffer prior to analysis. Two sets of serum standards were prepared as blank dilutions of 100 and 10010 fold. Standards and diluted serum samples were incubated on the plate for an hour. Bound anti-ALK-1 1.12.1 antibody (M29I / D19A) was detected using horseradish peroxidase-labeled (HRP) goat anti-human IgG (Fab-specific) antibody (Sigma, Cat. No. A0293). The substrate used was 3.3 ', 5.5'-tetramethylbenzidine (Sigma, catalog number T8665). Absorbance was read at 450 nm using a Vmax plate reader (Molecular Devices, Menlo Park, CA). The standard curve was fitted using nonlinear regression. The detection limit for this test was 10 ng / ml anti-ALK-1 1.12.1 antibody (M29I / D19A).
[0426] The concentration of anti-ALK-1 1.12.1 (M29I / D19A) antibody in the plasma of SCID mice is shown in Figure 15.
[0427] Figure 15 shows the estimated EC50 for 1.12.1 (M29I / D19A) in a chimera model
M24met SCID foreskin. The area of human vessels was plotted versus mean plasma PK over the entire study period (14 days) for each experimental group. The fitted curve was generated in the Sigmoidal Dose Dependent program from Graphpad (Prizm). An EC50 of 93 ng / ml was obtained from the fit curve (EC50 is defined as the plasma concentration required for a 50% reduction in the area of human vessels in the control group).
