FIELD OF THE INVENTION The present invention provides (i) an anti-LAG-3 antibody or antigen-binding fragment thereof or (ii) an anti-LAG-3 antibody or antigen-binding fragment thereof and an anti-PD-1 antibody, an anti-PD-L1 antibody or antigen-binding antibody thereof. It relates to pharmaceutical compositions comprising fragments. The invention also relates to pharmaceutical compositions comprising a buffer, stabilizer or bulking agent and a surfactant.

BACKGROUND OF THE INVENTION Lymphocyte activation gene-3 (LAG-3, LAG3 or CD223) is a type I transmembrane protein expressed on the cell surface of activated CD4+ and CD8+ T cells and a subset of NK and dendritic cells. (Triebel F., et al., J. Exp. Med. 1990; 171:1393-1405; Workman CJ, et al., J. Immunol. 2009; 182(4):1885-91). LAG-3 is closely associated with CD4, a co-receptor for T helper cell activation. Both molecules have four extracellular Ig-like domains and are required to bind their ligands, major histocompatibility complex (MHC) class II, for functional activity. In contrast to CD4, LAG-3 is only expressed on the cell surface of activated T cells and its cleavage from the cell surface shuts down LAG-3 signaling. LAG-3 also exists as a soluble protein, but it does not bind to MHC class II and its function is unknown.

LAG-3 has been reported to have an important role in promoting regulatory T cell (Treg) activity and negatively regulating T cell activation and proliferation (Workman CJ, et al., J. Immunol. 2005; 174:688-695). Both natural and induced Tregs express increased LAG-3, which is required for its maximal suppressive function (Camisaschi C., et al., J. Immunol. 2010; 184:6545- 6551 and Huang CT, et al., Immunity. 2004; 21:503-513). Furthermore, ectopic expression of LAG-3 on CD4+ effector T cells reduces their proliferative capacity and confers them regulatory capacity over third-party T cells (Huang CT, et al., Immunity. 2004; 21:503-513). Recent studies have shown that high LAG-3 expression on exhaustive lymphocytic choriomeningitis virus (LCMV)-specific CD8+ T cells contributes to their unresponsive state and limits CD8+ T cell anti-tumor responses. There are also studies (Blackburn SD, et al., Nat. Immunol. 2009; 10:29-37 and Grosso JF, et al., J. Clin. Invest. 2007; 117:3383-3392). Indeed, LAG-3 maintains tolerance to self and tumor antigens through direct effects on CD8+ T cells in two mouse models (Grosso JF, et al., J. Clin. Invest. 2007; 117 :3383-3392).

Programmed cell death 1 (PD-1) is a cell surface signaling receptor that has a key role in regulating T cell activation and tolerance (Keir ME, et al., Annu. Rev. Immunol. 2008; 26:677-704). It is a type I transmembrane protein and, together with BTLA, CTLA-4, ICOS and CD28, constitutes the CD28 family of T cell co-stimulatory receptors. PD-1 is expressed primarily on activated T cells, B cells and myeloid cells (Dong H., et al., Nat. Med. 1999; 5:1365-1369). It is also expressed in natural killer (NK) cells (Terme M., et al., Cancer Res. 2011; 71:5393-5399). Binding of PD-1 to its ligands, PD-L1 and PDL2, results in phosphorylation of tyrosine residues in the proximal intracellular immunoreceptor tyrosine-inhibitory domain, followed by recruitment of the phosphatase SHP-2 and final leading to downregulation of T cell activation. One important role of PD-1 is to limit T-cell activity in peripheral tissues during the inflammatory response to infection, thus limiting the development of autoimmunity (Pardoll DM, Nat. Rev. Cancer 2012; 12:252-264). Evidence for this negative regulatory role comes from the finding that PD-1-deficient mice develop lupus-like autoimmune diseases, including arthritis and nephritis, along with cardiomyopathy (Nishimura H., et al., Immunity, 1999; 11:141-151; and Nishimura H., et al., Science, 2001; 291:319-322). In the context of tumors, the development of immune tolerance within the microenvironment is the result. PD-1 is highly expressed on tumor-infiltrating lymphocytes and its ligand is upregulated on the cell surface of various tumors (Dong H., et al., Nat. Med. 2002; 8:793-800) . Multiple mouse cancer models have shown that ligand binding to PD-1 results in immune evasion. Furthermore, blocking this interaction results in anti-tumor activity (Topalian SL, et al. NEJM 2012; 366(26):2443-2454; Hamid O., et al., NEJM 2013; 369:134-144). Furthermore, inhibition of the PD-1/PD-L1 interaction has been shown to mediate potent anti-tumor activity in preclinical models (US Pat. Nos. 8,008,449 and 7,943,743).

<p>Patients with metastatic or refractory solid tumors have a very poor prognosis (Rosenberg SA, et al., Cancer immunotherapy in Cancer: Principles &amp; Practice of Oncology (Eds DeVita VT, Lawrence TS and Rosenberg SA) 2011; 332-344 (Lippincott Williams &amp; Wilkins, Philadelphia Pa.)). Despite advances in multimodal therapy, there has been limited increase in overall survival in this patient population. It is therefore an object of the present invention to provide improved methods of treating subjects with such tumors (eg, advanced refractory solid tumors).</p>

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. Concise Dictionary of Biomedicine and Molecular Biology, Juo, Pei-Show, 2nd ed., 2002, CRC Press; The Dictionary of Cell and Molecular Biology, 3rd ed., 1999, Academic Press; Biology, Revised, 2000, Oxford University Press, provides those skilled in the art with a general dictionary of many of the terms used herein.

Units, prefixes and symbols are given in the form accepted by the International System of Units (SI). Numeric ranges are inclusive of the numbers defining the range. The headings provided herein are not limitations of the various aspects of the disclosure that can be had by reference to the specification as a whole. Accordingly, the terms defined immediately below are more fully defined by reference to the specification as a whole.

"Administering" refers to the physical introduction of a composition containing a therapeutic agent to a subject using any of a variety of methods and delivery systems known to those of skill in the art. Preferred routes of administration of the formulations disclosed herein include intravenous, intramuscular, subcutaneous, intraperitoneal, spinal or other parenteral routes of administration, eg, by injection or infusion. As used herein, the term "parenteral administration" means modes of administration other than enteral and topical administration, usually by injection, including intravenous, intramuscular, intraarterial, intrathecal, intralymphatic, intralesional, intracapsular. , intraorbital, intracardiac, intradermal, intraperitoneal, transtracheal, subcutaneous, subcutaneous, intraarticular, subcapsular, intrathecal, intraspinal, epidural and intrasternal injections and infusions, as well as in vivo electroporation. Including but not limited to. In one embodiment, the formulation is administered by a non-parenteral route, preferably orally. Other non-parenteral routes include topical, epithelial or mucosal routes of administration such as intranasal, vaginal, rectal, sublingual or topical. Administration can also be carried out, for example, once, multiple times and/or over one or more periods of time.

An "antibody" (Ab) is a glycoprotein immunoglobulin or antigen-binding portion thereof that specifically binds to an antigen and comprises at least two heavy (H) chains and two light (L) chains interconnected by disulfide bonds including but not limited to. Each H chain consists of a heavy chain variable region (here V_H.) and heavy chain constant regions. The heavy chain constant region consists of three constant domains, C_H1, C_H2and C_H3including. Each light chain has a light chain variable region (here V_L.) and the light chain constant region. The light chain constant region consists of one constant domain, C_L.including. The VH and VL regions can be further subdivided into regions of hypervariability, termed complementarity determining regions (CDR), interspersed with regions that are more conserved, termed framework regions (FR). Each VH and VL contains three CDRs and four FRs, arranged from amino-terminus to carboxy-terminus in the following order: FR1, CDR1, FR2, CDR2, FR3, CDR3 and FR4. The heavy and light chain variable regions contain the binding domains that interact with antigen. The constant regions of antibodies may mediate the binding of immunoglobulins to host tissues or factors, including various cells of the immune system (eg, effector cells) and the first component (C1q) of the classical complement system. Heavy chains may or may not have a C-terminal lysine. Unless otherwise specified herein, variable region amino acids are numbered using the Kabat numbering system and constant region amino acids are numbered using the EU system.

Immunoglobulins may be derived from any of the commonly known isotypes, including but not limited to IgA, secretory IgA, IgG and IgM. IgG subclasses are also well known to those skilled in the art and include, but are not limited to, human IgG1, IgG2, IgG3 and IgG4. "Isotype" refers to the antibody class or subclass (eg, IgM or IgG1) that is encoded by the heavy chain constant region genes. The term "antibody" includes, by way of example, monoclonal and polyclonal antibodies; chimeric and humanized antibodies; human or non-human antibodies; fully synthetic antibodies; and single chain antibodies. A non-human antibody can be humanized by recombinant methods to reduce its immunogenicity in humans. Unless explicitly stated and indicated otherwise by the context, the term "antibody" includes mono-, bi- or multi-specific antibodies and single-chain antibodies. In some embodiments, the antibody is a bispecific antibody. In other embodiments, the antibody is a monospecific antibody.

As used herein, an "IgG antibody" has the structure of a naturally occurring IgG antibody, ie, has the same number of heavy and light chains and disulfide bonds as naturally occurring IgG antibodies of the same subclass. For example, an anti-ICOS IgG1, IgG2, IgG3 or IgG4 antibody consists of two heavy chains (HC) and two light chains (LC), wherein the two heavy and light chains are each naturally occurring. are linked by the same number and positions of disulfide bridges that are present in IgG1, IgG2, IgG3 and IgG4 antibodies (unless the antibody has been mutated such that the disulfide bonds are modified).

An antibody may be an antibody that has been modified (eg, by mutation, deletion, substitution, conjugation to non-antibody portions). For example, an antibody may contain one or more variant amino acids (compared to a naturally occurring antibody) that alter the properties (eg, functional properties) of the antibody. A number of such alterations are known in the art that affect, for example, half-life in a patient, effector function and/or immune response to antibodies. The term antibody also includes artificial polypeptide constructs that contain at least one antibody-derived antigen-binding site.

"Isolated antibody" refers to an antibody that is substantially free of other antibodies with different antigenic specificities (e.g., an isolated antibody that specifically binds PD-1 is specific for an antigen other than PD-1). ), however, an isolated antibody that specifically binds PD-1 may have cross-reactivity with other antigens, such as PD-1 molecules from different species. Moreover, an isolated antibody may be substantially free of other cellular material and/or chemicals.

The term "monoclonal antibody" ("mAb") refers to a preparation of non-naturally occurring antibody molecules of single molecular composition, i.e., essentially identical in primary sequence and possessing a single binding specificity for a particular epitope. Refers to an antibody molecule that exhibits sex and affinity. MAbs may be produced by hybridoma, recombinant, transgenic or other techniques known to those of skill in the art.

"Human" antibodies (HuMAbs) refer to antibodies having variable regions in which both the framework and CDR regions are derived from human germline immunoglobulin sequences. Furthermore, if the antibody contains a constant region, the constant region is also derived from human germline immunoglobulin sequences. Human antibodies of the invention may comprise amino acid residues not encoded by human germline immunoglobulin sequences (eg, mutations introduced by random or site-directed mutagenesis in vitro or by somatic mutation in vivo). However, the term "human antibody" as used herein is not intended to include antibodies in which CDR sequences from the germline of other mammalian species, such as mice, have been grafted onto human framework sequences. The terms "human" antibody and "fully human" antibody are used interchangeably.

A "humanized antibody" refers to an antibody in which some, most or all of the amino acids outside the CDR domains of a non-human antibody have been replaced with corresponding amino acids derived from human immunoglobulin. In certain embodiments of humanized forms of antibodies, some, most or all of the amino acids outside the CDR domains are replaced with amino acids from human immunoglobulins, while some, most or all of the amino acids within the CDR domains are replaced with amino acids from human immunoglobulins. Not all replaced. Minor additions, deletions, insertions, substitutions or modifications of amino acids are permissible as long as they do not abrogate the ability of the antibody to bind to the specific antigen. A "humanized" antibody retains antigen specificity similar to the original antibody.

A "chimeric antibody" refers to an antibody in which the variable region is derived from one species and the constant region is derived from another species, such as an antibody in which the variable region is derived from a murine antibody and the constant region is derived from a human antibody. .

An "anti-antigen" antibody refers to an antibody that specifically binds to said antigen. For example, an anti-PD-1 antibody specifically binds PD-1 and an anti-CTLA-4 antibody specifically binds CTLA-4.

An "antigen-binding portion" (also referred to as an "antigen-binding fragment") of an antibody refers to one or more fragments of an antibody that retain the ability of the whole antibody to specifically bind to the antibody. It has been shown that the antigen-binding function of antibodies can be performed by fragments or portions of full-length antibodies. Examples of binding fragments included within the term "antigen-binding portion" or "antigen-binding fragment" of an antibody, e.g., the anti-LAG-3 antibodies described herein, include (1) the VL, VH, LC and CH1 domains (2) an F(ab') comprising two Fab fragments linked by a disulfide bridge at the hinge region ;₂(3) an Fd fragment consisting of the VH and CH1 domains; (4) an Fv fragment consisting of the VL and VH domains of a single arm of an antibody; (5) a VH domain. , single domain antibody (dAb) fragments (Ward et al., (1989) Nature 341:544-46); (6) dual single domain antibodies (dual affinity (7) dual variable domain immunoglobulins; (8) isolated complementarity determining regions (CDRs); and (9) two or more isolated CDRs, optionally connected by synthetic linkers. Including combinations. In addition, the two domains of the Fv fragment, VL and VH, are encoded by separate genes, but were produced using recombinant methods as a single protein chain in which the VL and VH regions pair to form a monomolecular molecule. (known as single-chain Fv (scFv); see Bird et al. (1988) Science 242:423-426; and Huston et al. (1988) Proc. Natl. Acad. Sci. USA 85:5879-5883). Such single-chain antibodies are also intended to be encompassed by the term "antigen-binding portion" or "antigen-binding fragment" of an antibody. These antibody fragments are obtained using conventional techniques known to those of skill in the art, and the fragments are screened for utility in the same manner as intact antibodies. Antigen-binding portions may be produced by recombinant DNA techniques or by enzymatic or chemical cleavage of intact immunoglobulins.

"Cancer" refers to a diverse group of diseases characterized by the uncontrolled growth of abnormal cells in the body. Uncontrolled cell division and proliferation leads to the formation of malignant tumors that invade nearby tissues and may also metastasize to distant parts of the body via the lymphatic system or bloodstream. A "cancer" or "cancerous tissue" can include a tumor.

As used herein, the term "tumor" refers to any tissue mass, benign (non-cancerous) or malignant (cancerous), resulting from excessive cell growth or proliferation, including precancerous lesions.

"Disease" refers to any disorder in structure or function in an organism, e.g., a human, that is not directly attributable to physical injury; "infectious disease" refers to organisms such as bacteria, fungi, parasites, viruses or other pathogens refers to a disease caused by

The use of the term "fixed dose" in relation to the composition of the invention means that two or more different antibodies in a single composition are present in the composition in a specific (fixed) ratio to each other. In certain embodiments, a fixed dose is based on the weight (eg, mg) of antibody. In some embodiments, the fixed dose is based on antibody concentration (eg, mg/ml). In some embodiments, the ratio is at least about 1:1, about 1:2, about 1:3, about 1:4, about 1:5, about 1:6, about 1:7, about 1:8, about 1 :9, about 1:10, about 1:15, about 1:20, about 1:30, about 1:40, about 1:50, about 1:60, about 1:70, about 1:80, about 1 :90, about 1:100, about 1:120, about 1:140, about 1:160, about 1:180, about 1:200, about 200:1, about 180:1, about 160:1, about 140 :1, about 120:1, about 100:1, about 90:1, about 80:1, about 70:1, about 60:1, about 50:1, about 40:1, about 30:1, about 20 :1, about 15:1, about 10:1, about 9:1, about 8:1, about 7:1, about 6:1, about 5:1, about 4:1, about 3:1 or about 2 : 1 mg anti-LAG-3 antibody or antigen-binding fragment thereof against PD-1 antibody, anti-PD-L1 antibody or antigen-binding fragment thereof. For example, a 1:3 ratio of anti-LAG-3 antibody or antigen-binding fragment thereof to PD-1 antibody, anti-PD-L1 antibody or antigen-binding fragment thereof, is approximately 240 mg of anti-PD-1 antibody, anti-PD-L1 in a vial. antibody or antigen-binding fragment thereof and 80 mg of anti-LAG-3 antibody or antigen-binding fragment thereof; or about 3 mg/ml of anti-PD-1 antibody, anti-PD-L1 antibody or antigen-binding fragment thereof and 1 mg/ml of anti It may mean that it may comprise a LAG-3 antibody or antigen-binding fragment thereof.

The use of the term "flat dose" with respect to the compositions of the invention means the dose administered to a patient, regardless of the patient's weight or body surface area (BSA). Flat doses are therefore not provided as mg/kg doses, and agents (e.g., anti-LAG-3 antibodies or antigen-binding fragments thereof and/or anti-PD-1 antibodies, anti-PD-L1 antibodies or antigen-binding fragments thereof) provided as an absolute amount of For example, a 60 kg person and a 100 kg person receive the same dose of the composition (e.g., 240 mg of anti-PD-1 antibody, anti-PD-L1 antibody or antigen-binding fragment thereof and 80 mg of anti-LAG-3 antibody or antigen thereof). 240 mg of anti-PD-1 antibody, anti-PD-L1 antibody or antigen-binding fragment thereof and 80 mg of anti-LAG-3 antibody or antigen-binding fragment thereof (or 120 mg of anti-PD-L1 antibody) in a single fixed dose vial containing both binding fragments Two fixed dose formulation vials containing PD-1 antibody, anti-PD-L1 antibody or antigen-binding fragment thereof and 40 mg of anti-LAG-3 antibody or antigen-binding fragment thereof, etc.)).

As used herein, the term "weight-based dose" means that the dose administered to a patient is calculated based on the patient's weight. For example, when a patient weighing 60 kg requires a combination of 4 mg/kg of anti-PD-1 antibody and 1.33 mg/kg of anti-LAG-3 antibody, 1:3 of anti-LAG-3 antibody and anti-PD-1 antibody Appropriate amounts of anti-PD-1 antibody (eg, 240 mg) and anti-LAG-3 antibody (eg, 80 mg) can be readily removed from a fixed dose formulation.

As used herein, the term "control composition" refers to a composition that includes an anti-LAG-3 antibody (or, in antibody combination embodiments, an anti-PD-1 antibody, but not both). A control composition may comprise the same components as the composition except for the antibody (or, in antibody combination embodiments, the control composition may comprise the same components as the composition except for the antibody). In other embodiments, the control composition is the corresponding composition commercially available for the anti-PD-1 antibody, eg, Opdivo® or Keytruda®.

The terms "LAG-3", "LAG3" or "lymphocyte activation gene-3" refer to lymphocyte activation gene-3. The term LAG-3 as used herein includes human LAG-3 (hLAG-3), variants, isoforms, orthologs, paralogs and species homologs of hLAG-3 and analogs having at least one common epitope with hLAG-3. . The term LAG-3 as used herein includes variants, isoforms, homologs, orthologs and paralogs. For example, an antibody specific for a human LAG-3 protein may in some cases cross-react with LAG-3 proteins from species other than humans. In other embodiments, an antibody specific for human LAG-3 protein may be completely specific for human LAG-3 protein, exhibit no species or other types of cross-reactivity, or exhibit all It may cross-react with LAG-3 from certain other species but not other species (eg cross-react with monkey LAG-3 but not mouse LAG-3). The term "human LAG-3" refers to Genbank Accession No. It refers to human sequence LAG-3, such as the complete amino acid sequence of human LAG-3 having NP 002277. The term "mouse LAG-3" refers to the mouse sequence LAG-3, such as the complete amino acid sequence of mouse LAG-3 having Genbank Accession No. NP_032505. LAG-3 is also known in the art as, for example, CD223. The human LAG-3 sequence may differ from the human LAG-3 of Genbank Accession No. NP_002277, e.g., by having conservative or non-conserved region mutations, wherein LAG-3 is the human LAG-3 of Genbank Accession No. NP_002277. have substantially the same biological function as For example, the biological function of human LAG-3 is to have an epitope on the extracellular domain of LAG-3 that is specifically bound by an antibody of the invention, or the biological function of human LAG-3 is binding to MHC class II molecules.

A particular human LAG-3 sequence is generally at least 90% identical in amino acid sequence to the human LAG-3 of Genbank Accession No. NP_002277, and has a higher amino acid sequence identity when compared to the LAG-3 amino acid sequences of other species (e.g., mouse). It has amino acid residues that identify the sequence as human. In some cases, the human LAG-3 can be at least 95% identical in amino acid sequence to the LAG-3 of Genbank Accession No. NP_002277, or even at least 96%, 97%, 98% or 99% identical. In some embodiments, the human LAG-3 sequence has no more than 10 amino acid differences from the LAG-3 sequence of Genbank Accession No. NP_002277. In certain embodiments, the human LAG-3 may exhibit no more than 5 or no more than 4, 3, 2 or 1 amino acid differences from the LAG-3 sequence of Genbank Accession No. NP_002277. Percent identity can be determined as described herein.

The terms "programmed death 1", "programmed cell death 1", "protein PD-1", "PD-1", "PD1", "PDCD1", "hPD-1" and "hPD-I" as used herein are used interchangeably and include variants, isoforms, species homologues of human PD-1 and analogues having at least one common epitope with PD-1. The complete PD-1 sequence is shown under GenBank Accession No. U64863 (SEQ ID NO:29).

Protein programmed death 1 (PD-1) is an inhibitory member of the CD28 family of receptors that also includes CD28, CTLA-4, ICOS and BTLA. PD-1 is expressed on activated B cells, T cells and myeloid cells (Agata et al., supra; Okazaki et al. (2002) Curr. Opin. Immunol. 14: 391779-82; Bennett et al. ( 2003) J Immunol 170:711-8). Early members of this family, CD28 and ICOS, were discovered by their functional effects in enhancing T cell proliferation after addition of monoclonal antibodies (Hutloff et al. Nature (1999); 397:263-266; Hansen et al. Immunogenics ( 1980); 10:247-260). PD-1 was discovered by screening for differential expression in apoptotic cells (Ishida et al. EMBO J (1992); 11:3887-95). Other members of this family, CTLA-4 and BTLA, were discovered by screening for differential expression in cytotoxic T lymphocytes and TH1 cells, respectively. CD28, ICOS and CTLA-4 all have unpaired cysteine residues that allow homodimerization. In contrast, PD-1 lacks the unpaired cysteine residues characteristic of other CD28 family members, suggesting that it exists as a monomer.

The PD-1 gene is a 55 kDa type I transmembrane protein that is part of the Ig gene superfamily (Agata et al. (1996) Int Immunol 8:765-72). PD-1 contains a membrane proximal immunoreceptor tyrosine inhibitory motif (ITIM) and a membrane distal tyrosine-based switch motif (ITSM) (Thomas, ML (1995) J Exp Med 181:1953-6; Vivier, E and Daeron, M (1997) Immunol Today 18:286-91). PD-1 is structurally similar to CTLA-4 but lacks the MYPPPY motif (SEQ ID NO:32) important for B7-1 and B7-2 binding. Two ligands for PD-1, PD-L1 and PDL2, have been identified and shown to downregulate T cell activation upon binding to PD-1 (Freeman et al. (2000) J Exp Med 192:1027-34; Latchman et al. (2001) Nat Immunol 2:261-8; Carter et al. (2002) Eur J Immunol 32:634-43). Both PD-L1 and PDL2 are B7 homologs that bind PD-1 but not other CD28 family members. PD-L1 is abundant in a variety of human cancers (Dong et al. (2002) Nat. Med. 8:787-9). The interaction of PD-1 and PD-L1 leads to tumor-infiltrating lymphopenia, decreased T-cell receptor-mediated proliferation and immune evasion by cancer cells (Dong et al. (2003) J. Mol. Med. 81: 281-7; Blank et al. (2005) Cancer Immunol. Immunother. 54:307-314; Konishi et al. (2004) Clin. Cancer Res. 10:5094-100). Immunosuppression can be reversed by blocking the local interaction of PD-1 and PD-L1, and the effect is additive when the interaction of PD-1 and PDL2 is similarly blocked (Iwai et al. (2002). Proc. Nat'l. Acad. USA 99:12293-7; Brown et al. (2003) J. Immunol. 170:1257-66).

Consistent with PD-1 being an inhibitory member of the CD28 family, PD-1 deficient animals display a variety of autoimmune phenotypes, including autoimmune cardiomyopathy and lupus-like syndrome with arthritis and nephritis. (Nishimura et al. (1999) Immunity 11:141-51; Nishimura et al. (2001) Science 291:319-22). In addition, PD-1 has also been found to have a role in autoimmune encephalomyelitis, systemic lupus erythematosus, graft-versus-host disease (GVHD), type I diabetes and rheumatoid arthritis (Salama et al. (2003). ) J Exp Med 198:71-78; Prokunina and Alarcon-Riquelme (2004) Hum Mol Genet 13:R143; Nielsen et al. (2004) Lupus 13:510). In a murine B-cell tumor line, the ITSM of PD-1 regulates BCR-mediated Ca²⁺It has been shown to be essential for blocking tyrosine phosphorylation of currents and downstream effector molecules (Okazaki et al. (2001) PNAS 98:13866-71).

However, a significant decrease was observed up to 3 months at 40 °C or 6 months at 25 °C with increasing HMW and LMW. The HMW increase was more pronounced than the LMW increase. Table 11 shows that the increase in HMW and LMW was affected by pH, both increasing with decreasing pH value. Furthermore, the effect of the chelating agent DTPA is noticeable in Table 11. The DTPA-free formulation (F5.5N) exhibited approximately a 3-fold greater increase in HMW than the DTPA-containing formulation after exposure to 40°C for 3 months, indicating that increased stability was provided by DTPA.

All other samples were essentially unchanged from the beginning (&lt;1%). There was no difference between formulations with and without DTPA, indicating that CE-SDS purity was not affected by DTPA addition.

If charge degradants were formed, it was expected that the acidic peak would increase and the basic or main peak would decrease with time. The iCIEF results (Table, Table and Table) show no significant change in charge distribution from initial in samples exposed at -60 °C and 25 °C for up to 3 months or at RT/RL for 1 month ( &lt;5%). Significant changes were observed after 3 months at 40°C, which is not unexpected under such high load conditions. As expected, the acidic peak increased with increasing pH at 40°C, and the peak area increase was the result of peak area decreases for the main and basic peaks. These results indicate that all formulations are relatively stable in terms of charge distribution at the intended storage conditions of 28 °C for DP, but long-term high temperature exposure leads to BMS-986016 degradation, including deamidation by-products. This indicates that more acidic species are formed.</p><p>Table 14 also shows a significant difference (&gt;5%) in acidic species at 3 months at 40°C for DTPA and non-DTPA samples, indicating that DTPA enhanced the stability of the mAb's charge distribution.

It indicates that the product is relatively stable at pH 5.5±0.5 and the intended storage temperature of 2-8°C. High temperature exposure at 40 °C did not significantly change the appearance, pH, protein concentration and purity, but provided a strong signal for the formation of size- and charge-related degradants of this formulation under load conditions. Signals of size- and charge-related changes can be used to establish global pH stability profiles and select optimal formulation pH values. Figure 1 shows the percent degradants of these two main groups in samples at 40°C and various pH values. From the figure, an X-shaped profile is identified with a curve crossing at about pH 5.5. Profile curves show that size-related degradation products (HMW and LMW) increase with decreasing pH and charge-related degradation products (iCIEF acidic species) increase with increasing pH. A pH value of about 5.5 is the intersection point and minimizes the possibility of drug products deviating from specifications established by the iCIEF or SEC.</p><p>At low temperatures of 25°C, similar trends were seen at 40°C, but the differences between these two types of degradants were not strong between pH values (Fig. 2). No or negligible degradation occurred at 25°C for 3 months, suggesting that significantly longer exposures at 25°C may exhibit pH stability profiles similar to those observed at 40°C. There is</p><p>Furthermore, changing the concentration of anti-LAG-3 antibody (4 mg/ml vs. 12 mg/ml) did not change the percentage of acidic charge variants during storage at 5°C, 25°C or 40°C for 1-6 months. (Figures 3A and 3B).</p><p>Effect of Light on Drug Stability The effect of room temperature/room light (RT/RL) is shown in FIG. There was essentially no difference in appearance, pH, protein concentration, purity, HMW and LMW for light-exposed and dark samples for exposure duration (up to 1 month). The particle counts for both samples were also very low and within the limits specified by the USP. After 2 weeks exposure to room light, there is no increase in iCIEF acid peak area, and only a slight increase (approximately 2%) is shown at 1 month. This increase may be due to analytical method variation or due to actual trends in light-evoked responses. However, due to the relatively minor changes in acidic species (&lt;3%), there is no significant impact on drug quality. Based on the above comparison of light-exposed and shaded samples, it is concluded that there is adequate stability of the drug product under room lighting for up to 4 weeks.</p><p>Effect of DTPA on Drug Stability The effect of DTPA on DP stability is shown in FIG. Appearance, pH, protein concentration and purity of DTPA-containing samples were similar to those of DTPA-free samples after storage at 40°C for up to 3 months. Particle counts for all samples were low and within USP limits. However, at temperature challenge, there were more pronounced differences in HMW and LMW species levels between DTPA and non-DTPA samples. HMW and LMW species increased with time in all samples stored at 40°C, but increased at a slower rate in the DTPA-containing samples. After 1 month exposure at 40°C, there was no difference in iCIEF acidic peak area, but about 6% difference was observed at 3 months. Therefore, DTPA addition reduces the formation of both size- and charge-related fragments.</p><p>A comparison of DTPA and non-DTPA samples at 25°C is shown in Figure 5. No significant differences in appearance, pH, protein concentration, particle number, HMW, LMW, acidic variants and purity were observed in any of the samples. At 25°C at 3 months there was no or very little decomposition, making it difficult to assess the effects of DTPA at this temperature. Much longer exposure times may be necessary to provide a clear understanding of the differences between DTPA and non-DTPA samples. Available stability data at 25°C indicate that the drug product is relatively stable for long-term storage at the intended storage temperature of 2-8°C, even without DTPA.</p><p>However, the addition of DTPA to pharmaceutical formulations is expected to further increase stability and provide more product robustness under temperature or exposure conditions that may be encountered during manufacture, distribution and administration. A similar study with EDTA was performed with similar results (data not shown).</p><p><u style="Single">Conclusion</u>At 25°C for 3 months, no significant stability issues were observed with pH, particle count, protein concentration, purity, charge variants and aggregation, and the drug product is intended at 2-8°C within pH 5-6. Shows relative stability to long-term product storage conditions. pH was found to be a tumor-contributing factor that affected stability at temperatures as high as 40°C. An X-shaped pH stability profile was observed when two groups of degradation products, charge (iCIEF acidic group) and size-related (HMW and LMW) variants, were overlaid. The charge variant formulations increased with increasing pH value, and the size variant decreased with increasing pH value. The pH stability curve crosses at about pH 5.5, indicating optimum stability at this pH.</p><p>In addition, there was no significant difference in stability over a 1-month period for light-exposed and shaded samples, which supports manufacturing, storage, distribution and administration of pharmaceutical products under short-term room-light conditions.</p><p>Addition of D TPA increased drug stability based on data obtained at 40°C. DTPA or EDTA are expected to significantly further extend drug shelf life when stored at 2-8°C.</p><p>Example 3 The effect of chelating agents on aggregation of the compositions of the invention was further tested. Compositions comprising an anti-LAG-3 antibody alone (aLAG-3 Mono) or an anti-LAG-3 antibody and an anti-PD-1 antibody (aLAG-3 FDRC) in a 1:1 fixed dose ratio combination are described in other examples. Prepared as follows. The final 1:1 aLAG-3 FDRC composition contained 12 mg/ml anti-LAG-3 antibody, 12 mg/ml nivolumab, 20 mM histidine, 250 mM sucrose and 0.05% (w/v) polysorbate 80 (PS80).</p><p>Compositions also contained 20 μM-100 μM DTPA or 20 μM-250 μM EDT, and 1-5 ppm metal was added to induce aggregation (1 ppm or 5 ppm total at 200 ppb or 1,000 ppb Fe, Ni, Cr, Cu and Zn, respectively). . The compositions were stored at 40°C or room temperature (RT/RL) for 1 month and HMW aggregates were measured as described in Example 2.</p><p>The percentage of HMW aggregates for aLAG-3 Mono and aLAG-3 FDRC compositions are shown in Figures 7 and 8, respectively. The presence of metals resulted in significant aggregation at 40°C in the absence of chelators for both aLAG-3 Mono and FDRC, but was more enhanced for the aLAG3 Mono composition. However, both DTPA and EDTA effectively reduced metal-induced aggregation at 40°C or RT/RL.</p><p>Example 4 The stability performance of the 1:3 fixed dose ratio combination of the present invention was tested. A composition comprising anti-LAG-3 and anti-PD-1 antibodies and DTPA in a 1:3 fixed dose ratio combination (1:3 FDRC) was prepared as described in other examples, with a final composition of 12 mg/ Contains nivolumab (Nivo), 4 mg/ml anti-LAG-3 antibody. Compositions containing anti-LAG-3 antibodies without anti-PD-1 antibodies and containing anti-PD-1 antibodies without anti-LAG-3 antibodies were also tested for comparison. Compositions were stored at 60° C., 5° C., 25° C. or 40° C. for 3 months and charge distribution changes of formulation samples were measured by iCIEF as described in Example 2.</p><p>iCIEF results for anti-PD-1 antibody (Figure 9A) and anti-LAG-3 antibody (Figure 9B) are similar to anti-PD-1 antibody or anti-LAG-3 antibody alone in the same buffer system in 1:3 FDRC. Stability patterns for both antibodies are shown.</p><p>Example 5 The 12-month stability performance of the fixed dose ratio combination (FDRC) of the present invention was also tested.

A composition comprising anti-LAG-3 antibody without anti-PD-1 antibody (nivolumab, Nivo) was also tested for comparison.

Additional stability measurements are reported in Tables 17 and 18. Specifically, Table 17 shows that the 3:1 and 1:1 (anti-PD-1 antibody:anti-LAG-3 antibody) FDRC formulations increased total protein concentration after 3 months under accelerated and/or stressed temperature/light conditions. or that there was essentially no change in pH.</p><p><tables><img file="JP7301002B2_D0019.tif" /></tables><tables><img file="JP7301002B2_D0020.tif" /></tables></p><p>The stability performance of the Example 6 FDRC composition was also evaluated by measuring oxidation and deamidation. Compositions containing anti-PD-1 and anti-LAG-3 antibodies at 1:3 and 1:1 (anti-LAG-3 antibody:anti-PD-1 antibody) FDRC were prepared as described in other examples. Compositions were stored at 40°C for 3 months and tryptic peptide mapping assays were performed to measure deamidation and oxidation. Specifically, samples were reduced, alkylated and digested with trypsin. Tryptic peptides were separated on a C18 column and detected with a UV detector at 215 nm and 280 nm followed by a mass spectrometer (LTQ-Orbitrap-Elite). Relative quantification was achieved by comparison of peak areas between intact and modified peptides on selected ion chromatograms.</p><p>The results of the assay are shown in Figures 11A-11C. No significant methionine (Met) or tryptophan (Trp) oxidation was observed in the formulations (Figures 11A and 11B, respectively).
