Therapeutic uses of empagliflozin

PHARMACEUTICAL COMPOSITION, METHODS FOR TREATING AND USES THEREOF

Technical Field of the Invention

The present invention relates to certain SGLT-2 inhibitors for treating and/or preventing oxidative stress, for example in patients with type 1 or type 2 diabetes mellitus, as well as to the use of such SGLT-2 inhibitors in treatment and/or prevention of cardiovascular diseases in patients, for example type 1 or type 2 diabetes mellitus patients. The present invention further relates to certain SGLT-2 inhibitors for treating and/or preventing a metabolic disorder and preventing, reducing the risk of or delaying the occurrence of a cardiovascular event in patients, for example patients with type 1 or type 2 diabetes mellitus.

Background of the Invention

The rising prevalences of type 2 diabetes mellitus (T2DM) represent major challenges for global public health. Worldwide, there are more than 220 million patients with type 2 diabetes mellitus, figures which are projected to rise by 2030 (World Health Organisation 2010; International Diabetes Federation 2010). According to the US Centers for Disease Control and Prevention, rates of type 2 diabetes mellitus have tripled in the past 30 years. Diabetes now affects an estimated 23.6 million people in the United States; another 57 million have prediabetes. Prediabetes raises short-term absolute risk of type 2 diabetes mellitus five- to sixfold.

Type 2 diabetes mellitus is an increasingly prevalent disease that due to a high frequency of complications leads to a significant reduction of life expectancy. Because of diabetesassociated microvascular complications, type 2 diabetes is currently the most frequent cause of adult-onset loss of vision, renal failure, and amputations in the industrialized world. In addition, the presence of type 2 diabetes mellitus is associated with a two to five fold increase in cardiovascular disease risk.

After long duration of disease, most patients with type 2 diabetes mellitus will eventually fail on oral therapy and become insulin dependent with the necessity for daily injections and multiple daily glucose measurements.

The UKPDS (United Kingdom Prospective Diabetes Study) demonstrated that intensive treatment with metformin, sulfonylureas or insulin resulted in only a limited improvement of glycemic control (difference in HbA1c -0.9%). In addition, even in patients within the intensive treatment arm glycemic control deteriorated significantly over time and this was

02831903\l-01 attributed to deterioration of β-cell function. Therefore many patients with type 2 diabetes mellitus remain inadequately treated, partly because of limitations in long term efficacy, tolerability and dosing inconvenience of existing antihyperglycemic therapies.

Oral antidiabetic drugs conventionally used in therapy (such as e.g. first- or second-line, and/or mono- or (initial or add-on) combination therapy) include, without being restricted thereto, metformin, sulphonylureas, thiazolidinediones, glinides, DPP-4 inhibitors and aglucosidase inhibitors.

The high incidence of therapeutic failure is a major contributor to the high rate of long-term hyperglycemia-associated complications or chronic damages (including micro- and macrovascular complications such as e.g. diabetic nephrophathy, retinopathy or neuropathy, or cardiovascular complications) in patients with type 2 diabetes mellitus.

Therefore, there is an unmet medical need for methods, medicaments and pharmaceutical compositions with a good efficacy with regard to glycemic control, with regard to diseasemodifying properties and with regard to reduction of cardiovascular morbidity and mortality while at the same time showing an improved safety profile.

Summary of the Invention

The present invention relates to certain SGLT-2 inhibitors for treating and/or preventing oxidative stress, for example in patients with type 1 or type 2 diabetes mellitus. The present invention also relates to the use of such SGLT-2 inhibitors in the treatment and/or prevention of cardiovascular diseases in patients, for example in type 1 or type 2 diabetes mellitus patients. The present invention also relates to the use of such SGLT-2 inhibitors in treatment and/or prevention of a metabolic disorder in patients with or at risk of cardiovascular disease. The present invention further relates to certain SGLT-2 inhibitors for treating and/or preventing a metabolic disorder and preventing, reducing the risk of or delaying the occurrence of a cardiovascular event in patients, for example patients with type 1 or type 2 diabetes mellitus. The present invention also further relates to certain SGLT-2 inhibitors for preventing, slowing, delaying or treating the degeneration of pancreatic beta cells and/or the decline of the functionality of pancreatic beta cells and/or for improving and/or restoring the functionality of pancreatic beta cells and/or restoring the functionality of pancreatic insulin secretion in patients having latent autoimmune diabetes in adults (LADA).

Definitions

The term active ingredient of a pharmaceutical composition according to the present invention means the SGLT2 inhibitor according to the present invention. An “active ingredient is also sometimes referred to herein as an “active substance”.

The term body mass index or BMI of a human patient is defined as the weight in kilograms divided by the square of the height in meters, such that BMI has units of kg/m2.

The term overweight is defined as the condition wherein the individual has a BMI greater than or 25 kg/m2 and less than 30 kg/m2. The terms overweight and pre-obese are used interchangeably.

02831903\l-01

The terms obesity or “being obese” and the like are defined as the condition wherein the individual has a BMI equal to or greater than 30 kg/m2. According to a WHO definition the term obesity may be categorized as follows: the term class I obesity is the condition wherein the BMI is equal to or greater than 30 kg/m2 but lower than 35 kg/m2; the term class II obesity is the condition wherein the BMI is equal to or greater than 35 kg/m2 but lower than 40 kg/m2; the term class III obesity is the condition wherein the BMI is equal to or greater than 40 kg/m2.

The indication obesity includes in particular exogenic obesity, hyperinsulinaemic obesity, hyperplasmic obesity, hyperphyseal adiposity, hypoplasmic obesity, hypothyroid obesity, hypothalamic obesity, symptomatic obesity, infantile obesity, upper body obesity, alimentary obesity, hypogonadal obesity, central obesity, visceral obesity, abdominal obesity.

The term visceral obesity is defined as the condition wherein a waist-to-hip ratio of greater than or equal to 1.0 in men and 0.8 in women is measured. It defines the risk for insulin resistance and the development of pre-diabetes.

The term abdominal obesity is usually defined as the condition wherein the waist circumference is > 40 inches or 102 cm in men, and is > 35 inches or 94 cm in women. With regard to a Japanese ethnicity or Japanese patients abdominal obesity may be defined as waist circumference > 85 cm in men and > 90 cm in women (see e.g. investigating committee for the diagnosis of metabolic syndrome in Japan).

The term “euglycemia” is defined as the condition in which a subject has a fasting blood glucose concentration within the normal range, greater than 70 mg/dL (3.89 mmol/L) and less than 100 mg/dL (5.6 mmol/L). The word “fasting” has the usual meaning as a medical term.

The term “hyperglycemia” is defined as the condition in which a subject has a fasting blood glucose concentration above the normal range, greater than 100 mg/dL (5.6 mmol/L). The word “fasting” has the usual meaning as a medical term.

The term “hypoglycemia” is defined as the condition in which a subject has a blood glucose concentration below the normal range, in particular below 70 mg/dL (3.89 mmol/L).

02831903\l-01

The term postprandial hyperglycemia is defined as the condition in which a subject has a 2 hour postprandial blood glucose or serum glucose concentration greater than 200 mg/dL (11.11 mmol/L).

The term “impaired fasting blood glucose” or IFG is defined as the condition in which a subject has a fasting blood glucose concentration or fasting serum glucose concentration in a range from 100 to 125 mg/dl (i.e. from 5.6 to 6.9 mmol/l), in particular greater than 110 mg/dL and less than 126 mg/dl (7.00 mmol/L). A subject with normal fasting glucose has a fasting glucose concentration smaller than 100 mg/dl, i.e. smaller than 5.6 mmol/l.

The term “impaired glucose tolerance” or IGT is defined as the condition in which a subject has a 2 hour postprandial blood glucose or serum glucose concentration greater than 140 mg/dl (7.78 mmol/L) and less than 200 mg/dL (11.11 mmol/L). The abnormal glucose tolerance, i.e. the 2 hour postprandial blood glucose or serum glucose concentration can be measured as the blood sugar level in mg of glucose per dL of plasma 2 hours after taking 75 g of glucose after a fast. A subject with normal glucose tolerance has a 2 hour postprandial blood glucose or serum glucose concentration smaller than 140 mg/dl (7.78 mmol/L).

The term “hyperinsulinemia” is defined as the condition in which a subject with insulin resistance, with or without euglycemia, has fasting or postprandial serum or plasma insulin concentration elevated above that of normal, lean individuals without insulin resistance, having a waist-to-hip ratio <1.0 (for men) or < 0.8 (for women).

The terms insulin-sensitizing, insulin resistance-improving or insulin resistance-lowering” are synonymous and used interchangeably.

The term “insulin resistance” is defined as a state in which circulating insulin levels in excess of the normal response to a glucose load are required to maintain the euglycemic state (Ford ES, et al. JAMA. (2002) 287:356-9). A method of determining insulin resistance is the euglycaemic-hyperinsulinaemic clamp test. The ratio of insulin to glucose is determined within the scope of a combined insulin-glucose infusion technique. There is found to be insulin resistance if the glucose absorption is below the 25th percentile of the background population investigated (WHO definition). Rather less laborious than the clamp test are so called minimal models in which, during an intravenous glucose tolerance test, the insulin and glucose concentrations in the blood are measured at fixed time intervals and from these the insulin resistance is calculated. With this method, it is not possible to distinguish between hepatic and peripheral insulin resistance.

02831903\l-01

Furthermore, insulin resistance, the response of a patient with insulin resistance to therapy, insulin sensitivity and hyperinsulinemia may be quantified by assessing the “homeostasis model assessment to insulin resistance (HOMA-IR)” score, a reliable indicator of insulin resistance (Katsuki A, et al. Diabetes Care 2001; 24: 362-5). Further reference is made to methods for the determination of the HOMA-index for insulin sensitivity (Matthews et al., Diabetologia 1985, 28: 412-19), of the ratio of intact proinsulin to insulin (Forst et al., Diabetes 2003, 52(Suppl.1): A459) and to an euglycemic clamp study. In addition, plasma adiponectin levels can be monitored as a potential surrogate of insulin sensitivity. The estimate of insulin resistance by the homeostasis assessment model (HOMA)-IR score is calculated with the formula (Galvin P, et al. Diabet Med 1992;9:921-8):

HOMA-IR = [fasting serum insulin (pU/mL)] x [fasting plasma glucose(mmol/L)/22.5]

Insulin resistance can be confirmed in these individuals by calculating the HOMA-IR score. For the purpose of this invention, insulin resistance is defined as the clinical condition in which an individual has a HOMA-IR score > 4.0 or a HOMA-IR score above the upper limit of normal as defined for the laboratory performing the glucose and insulin assays.

As a rule, other parameters are used in everyday clinical practice to assess insulin resistance. Preferably, the patient's triglyceride concentration is used, for example, as increased triglyceride levels correlate significantly with the presence of insulin resistance.

Individuals likely to have insulin resistance are those who have two or more of the following attributes: 1) overweight or obese, 2) high blood pressure, 3) hyperlipidemia, 4) one or more 1st degree relative with a diagnosis of IGT or IFG or type 2 diabetes.

Patients with a predisposition for the development of IGT or IFG or type 2 diabetes are those having euglycemia with hyperinsulinemia and are by definition, insulin resistant. A typical patient with insulin resistance is usually overweight or obese. If insulin resistance can be detected, this is a particularly strong indication of the presence of pre-diabetes. Thus, it may be that in order to maintain glucose homoeostasis a person needs 2-3 times as much insulin as a healthy person, without this resulting in any clinical symptoms.

“Pre-diabetes” is a general term that refers to an intermediate stage between normal glucose tolerance (NGT) and overt type 2 diabetes mellitus (T2DM), also referred to as intermediate hyperglycaemia. As such, it represents 3 groups of individuals, those with

02831903\l-01 impaired glucose tolerance (IGT) alone, those with impaired fasting glucose (IFG) alone or those with both IGT and IFG. IGT and IFG usually have distinct pathophysiologic etiologies, however also a mixed condition with features of both can exist in patients. Therefore in the context of the present invention a patient being diagnosed of having “pre-diabetes” is an individual with diagnosed IGT or diagnosed IFG or diagnosed with both IGT and IFG. Following the definition according to the American Diabetes Association (ADA) and in the context of the present invention a patient being diagnosed of having “pre-diabetes” is an individual with:

a) a fasting plasma glucose (FPG) concentration <100 mg/dL [1 mg/dL = 0.05555 mmol/L] and a 2-hour plasma glucose (PG) concentration, measured by a 75-g oral glucose tolerance test (OGTT), ranging between >140 mg/dL and <200 mg/dL (i.e., IGT); or

b) a fasting plasma glucose (FPG) concentration between >100 mg/dL and <126 mg/dL and a 2-hour plasma glucose (PG) concentration, measured by a 75-g oral glucose tolerance test (OGTT) of <140 mg/dL (i.e., IFG); or

c) a fasting plasma glucose (FPG) concentration between >100 mg/dL and <126 mg/dL and a 2-hour plasma glucose (PG) concentration, measured by a 75-g oral glucose tolerance test (OGTT), ranging between >140 mg/dL and <200 mg/dL (i.e., both IGT and IFG).

Patients with “pre-diabetes” are individuals being pre-disposed to the development of type 2 diabetes. Pre-diabetes extends the definition of IGT to include individuals with a fasting blood glucose within the high normal range >100 mg/dL (J. B. Meigs, etal. Diabetes 2003; 52:1475-1484). The scientific and medical basis for identifying pre-diabetes as a serious health threat is laid out in a Position Statement entitled The Prevention or Delay of Type 2 Diabetes issued jointly by the American Diabetes Association and the National Institute of Diabetes and Digestive and Kidney Diseases (Diabetes Care 2002; 25:742-749).

The methods to investigate the function of pancreatic beta-cells are similar to the above methods with regard to insulin sensitivity, hyperinsulinemia or insulin resistance: An improvement of beta-cell function can be measured for example by determining a HOMAindex (homeostasis model assessment) for beta-cell function, HOMA-B, (Matthews etal., Diabetologia 1985, 28: 412-19), the ratio of intact proinsulin to insulin (Forst et al., Diabetes 2003, 52(Suppl. 1): A459), first and second phase insulin secretion after an oral glucose tolerance test or a meal tolerance test (Stumvoll et al., Diabetes care 2000, 23: 295-301), the insulin/C-peptide secretion after an oral glucose tolerance test or a meal tolerance test, or by employing a hyperglycemic clamp study and/or minimal modeling after a frequently sampled intravenous glucose tolerance test (Stumvoll et al., EurJ Clin Invest 2001, 31:380-81).

02831903\l-01

The term “type 1 diabetes” is defined as the condition in which a subject has, in the presence of autoimmunity towards the pancreatic beta-cell or insulin, a fasting blood glucose or serum glucose concentration greater than 125 mg/dL (6.94 mmol/L). If a glucose tolerance test is carried out, the blood sugar level of a diabetic will be in excess of 200 mg of glucose per dL (11.1 mmol/l) of plasma 2 hours after 75 g of glucose have been taken on an empty stomach, in the presence of autoimmunity towards the pancreatic beta cell or insulin. In a glucose tolerance test 75 g of glucose are administered orally to the patient being tested after 10-12 hours of fasting and the blood sugar level is recorded immediately before taking the glucose and 1 and 2 hours after taking it. The presence of autoimmunity towards the pancreatic beta-cell may be observed by detection of circulating islet cell autoantibodies [“type 1A diabetes mellitus”], i.e., at least one of: GAD65 [glutamic acid decarboxylase-65], ICA [islet-cell cytoplasm], IA-2 [intracytoplasmatic domain of the tyrosine phosphatase-like protein IA-2], ZnT8 [zinc-transporter-8] or anti-insulin; or other signs of autoimmunity without the presence of typical circulating autoantibodies [type 1B diabetes], i.e. as detected through pancreatic biopsy or imaging). Typically a genetic predisposition is present (e.g. HLA, //VS VNTR and PTPN22), but this is not always the case.

The term “type 2 diabetes mellitus” or “T2DM” is defined as the condition in which a subject has a fasting blood glucose or serum glucose concentration greater than 125 mg/dL (6.94 mmol/L). The measurement of blood glucose values is a standard procedure in routine medical analysis. If a glucose tolerance test is carried out, the blood sugar level of a diabetic will be in excess of 200 mg of glucose per dL (11.1 mmol/l) of plasma 2 hours after 75 g of glucose have been taken on an empty stomach. In a glucose tolerance test 75 g of glucose are administered orally to the patient being tested after 10-12 hours of fasting and the blood sugar level is recorded immediately before taking the glucose and 1 and 2 hours after taking it. In a healthy subject, the blood sugar level before taking the glucose will be between 60 and 110 mg per dL of plasma, less than 200 mg per dL 1 hour after taking the glucose and less than 140 mg per dL after 2 hours. If after 2 hours the value is between 140 and 200 mg, this is regarded as abnormal glucose tolerance.

The term late stage type 2 diabetes mellitus includes patients with a secondary drug failure, indication for insulin therapy and progression to micro- and macrovascular complications e.g. diabetic nephropathy, or coronary heart disease (CHD).

The term “LADA” (“latent autoimmune diabetes of adults”) refers to patients that have a clinical diagnosis of type 2 diabetes, but who are being detected to have autoimmunity towards the pancreatic beta cell. Latent autoimmune diabetes of adults (LADA) is also known

02831903\l-01 as slowly progressive type 1 diabetes mellitus (T1DM), “mild” T1DM, non-insulin dependent type 1 DM, type 1 % DM, double diabetes or antibody positive type 2 DM (T2DM). LADA is often not clearly defined and, opposed to T1DM, seldom or never presents with significant weight loss and ketoacidosis due to rapidly progressive β-cell failure.

The term HbA1c refers to the product of a non-enzymatic glycation of the haemoglobin B chain. Its determination is well known to one skilled in the art. In monitoring the treatment of diabetes mellitus the HbA1c value is of exceptional importance. As its production depends essentially on the blood sugar level and the life of the erythrocytes, the HbA1c in the sense of a blood sugar memory reflects the average blood sugar levels of the preceding 4-6 weeks. Diabetic patients whose HbA1c value is consistently well adjusted by intensive diabetes treatment (i.e. &lt; 6.5 % of the total haemoglobin in the sample), are significantly better protected against diabetic microangiopathy. For example, metformin on its own achieves an average improvement in the HbA1 c value in the diabetic of the order of 1.0 - 1.5 %. This reduction of the HbA1C value is not sufficient in all diabetics to achieve the desired target range of &lt;7% or &lt; 6.5 % and preferably &lt; 6 % HbA1c.

The term insufficient glycemic control or inadequate glycemic control in the scope of the present invention means a condition wherein patients show HbA1c values above 6.5 %, in particular above 7.0 %, even more preferably above 7.5 %, especially above 8 %.

The “metabolic syndrome”, also called “syndrome X” (when used in the context of a metabolic disorder), also called the “dysmetabolic syndrome” is a syndrome complex with the cardinal feature being insulin resistance (Laaksonen DE, et al. Am J Epidemiol 2002;156:1070-7). According to the ATP Ill/NCEP guidelines (Executive Summary of the Third Report of the National Cholesterol Education Program (NCEP) Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (Adult Treatment Panel III) JAMA: Journal of the American Medical Association (2001) 285:2486-2497), diagnosis of the metabolic syndrome is made when three or more of the following risk factors are present:

1. Abdominal obesity, defined as waist circumference > 40 inches or 102 cm in men, and > 35 inches or 94 cm in women; or with regard to a Japanese ethnicity or Japanese patients defined as waist circumference > 85 cm in men and > 90 cm in women;

2. Triglycerides: >150 mg/dL

3. HDL-cholesterol &lt; 40 mg/dL in men

4. Blood pressure > 130/85 mm Hg (SBP > 130 or DBP > 85)

02831903\l-01

5. Fasting blood glucose >100 mg/dL

The NCEP definitions have been validated (Laaksonen DE, et al. Am J Epidemiol. (2002) 156:1070-7). Triglycerides and HDL cholesterol in the blood can also be determined by standard methods in medical analysis and are described for example in Thomas L (Editor): Labor und Diagnose“, TH-Books Verlagsgesellschaft mbH, Frankfurt/Main, 2000.

According to a commonly used definition, hypertension is diagnosed if the systolic blood pressure (SBP) exceeds a value of 140 mm Hg and diastolic blood pressure (DBP) exceeds a value of 90 mm Hg. If a patient is suffering from manifest diabetes it is currently recommended that the systolic blood pressure be reduced to a level below 130 mm Hg and the diastolic blood pressure be lowered to below 80 mm Hg.

The term empagliflozin refers to the SGLT2 inhibitor 1-chloro (P&amp;#1470;D-glucopyranos yl)2-[4-((S)-tetrahydrofuran yloxy)-benzyl]-benzene of the formula as described for example in WO 2005/092877. Methods of synthesis are described in the literature, for example WO 06/120208 and WO 2011/039108. According to this invention, it is to be understood that the definition of empagliflozin also comprises its hydrates, solvates and polymorphic forms thereof, and prodrugs thereof. An advantageous crystalline form of empagliflozin is described in WO 2006/117359 and WO 2011/039107 which hereby are incorporated herein in their entirety. This crystalline form possesses good solubility properties which enables a good bioavailability of the SGLT2 inhibitor. Furthermore, the crystalline form is physico-chemically stable and thus provides a good shelf-life stability of the pharmaceutical composition. Preferred pharmaceutical compositions, such as solid formulations for oral administration, for example tablets, are described in WO 2010/092126, which hereby is incorporated herein in its entirety.

The terms treatment and treating comprise therapeutic treatment of patients having already developed said condition, in particular in manifest form. Therapeutic treatment may be symptomatic treatment in order to relieve the symptoms of the specific indication or causal treatment in order to reverse or partially reverse the conditions of the indication or to

02831903)1-01 stop or slow down progression of the disease. Thus the compositions and methods of the present invention may be used for instance as therapeutic treatment over a period of time as well as for chronic therapy.

The terms prophylactically treating, preventivally treating and preventing are used interchangeably and comprise a treatment of patients at risk to develop a condition mentioned hereinbefore, thus reducing said risk.

The term tablet comprises tablets without a coating and tablets with one or more coatings. Furthermore the term tablet comprises tablets having one, two, three or even more layers and press-coated tablets, wherein each of the beforementioned types of tablets may be without or with one or more coatings. The term ”tablet” also comprises mini, melt, chewable, effervescent and orally disintegrating tablets.

The terms pharmacopoe and pharmacopoeias refer to standard pharmacopoeias such as the “USP 31-NF 26 through Second Supplement” (United States Pharmacopeial Convention) or the “European Pharmacopoeia 6.3” (European Directorate for the Quality of Medicines and Health Care, 2000-2009).

Oxidative stress represents an imbalance between the production of reactive oxygen species (which include free radicals, which typically have an oxygen- or nitrogen based unpaired electron in their outer orbitals and peroxides) and a biological system's ability to readily detoxify the reactive intermediates or to repair the resulting damage. Disturbances in the normal redox state of tissues can cause toxic effects through the production of peroxides and free radicals that damage all components of the cell, including proteins, lipides and nucleic acid/DNA. Oxidative stress can target many organs (such as blood vessels, eyes, heart, skin, kidney, joints, lung, brain, immune system, liver, or multi-organs) and can be involved in many diseases and conditions. Examples of such diseases or conditions associated with oxidative stress include atherosclerosis (e.g. platelet activation and atheromatous plaque formation), endothelial dysfunction, restenosis, hypertension, peripheral occlusive vascular disease, ischemia-reperfusion injuries (e.g. renal, hepatic, cardiac or cerebral ischemiareperfusion injuries), fibrosis (e.g. renal, hepatic, cardiac or pulmonary fibrosis); macular degeneration, retinal degeneration, cateracts, retinopathy; coronary heart disease, ischemia, myocardial infarction; psoriasis, dermatitis; chronic kidney disease, nephritis, acute renal failure, glomerulonephritis, nephropathy; rheumatoid arthritis, osteoarthritis; asthma, COPD, respiratory distress syndrome; stroke, neurodegenerative diseases (e.g. Alzheimer’s disease, Parkinson’s disease, Huntington’s disease), schizophrenia, bipolar disorder, obsessive compulsive disorder; chronic systemic inflammations, perivascular inflammation, autoimmune disorders, multiple sclerosis, lupus erythematosus, inflammatory bowel disease, ulcerative colitis; NAFLD/NASH; chronic fatigue syndrome, polycystic ovary syndrome, sepsis, diabetes, metabolic syndrome, insulin resistance, hyperglycemia, hyperinsulinemia, dyslipidemia, hypercholesterolemia, hyperlipidemia, etc. In addition to their original

02831903\l-01 pharmacological properties, certain drugs used clinically, including, without being limited, anti-hypertension agents, angiotensin receptor blockers and antihyperlipidemic agents such as statins, protect various organs via anti-oxidative stress mechanisms.

Patients with or at risk of oxidative and/or vascular stress can be diagnosed by determining patient’s oxidative stress markers, such as e.g. oxidized LDL, markers of inflammatory status (e.g. pro-inflammatory interleukins), 8-OHdG, isoprostanes (e.g. F2-isoprostanes, 8-isoprostaflandin F2alpha), nitrotyrosine, or N-carboxymethyl lysine (CML).

Endothelial dysfunction, commonly assessed clinically as impaired endothelium-dependent vasomotion (e.g. imbalance between vasodilating and vasoconstricting), is a physiological disability of endothelial cells, the cells that line the inner surface of blood vessels, arteries and veins, that prevents them from carrying out their normal biochemical functions. Normal endothelial cells are involved in mediating the processes of coagulation, platelet adhesion, immune function, control of volume and electrolyte content of the intravascular and extravascular spaces. Endothelial dysfunction is associated with proinflammatory, prooxidative and prothrombotic changes within the arterial wall as well as increase vessel wall thickness and collagen content. Endothelial dysfunction is thought to be a key event in the development and progression of atherosclerosis and arterial stiffness, and predates clinically obvious vascular complications. Endothelial dysfunction is of prognostic significance in detecting vascular disease and predicting adverse vascular events. Risk factors for atherosclerosis and vascular disease/events are associated with endothelial dysfunction. Endothelial damage also contributes to the development of renal injury and/or chronic or progressive kidney damages, such as e.g. tubulointerstitial fibrosis, glomerulonephritis, micro-or macroalbuminuria, nephropathy and/or chronic kidney disease or renal failure. There is supporting evidence that oxidative stress does not only contribute to endothelial dysfunction or damage but also to vascular disease.

Type 2 diabetes mellitus is a common chronic and progressive disease arising from a complex pathophysiology involving the dual endocrine effects of insulin resistance and impaired insulin secretion with the consequence not meeting the required demands to maintain plasma glucose levels in the normal range. This leads to hyperglycaemia and its associated micro- and macrovascular complications or chronic damages, such as e.g. diabetic nephropathy, retinopathy or neuropathy, or macrovascular (e.g. cardiovascular) complications. The vascular disease component plays a significant role, but is not the only factor in the spectrum of diabetes associated disorders. The high frequency of complications leads to a significant reduction of life expectancy. Diabetes is currently the most frequent

02831903\l-01 cause of adult-onset loss of vision, renal failure, and amputation in the Industrialised World because of diabetes induced complications and is associated with a two to five fold increase in cardiovascular disease risk. Type 1 diabetes mellitus (Type 1 diabetes), also called insulin dependent diabetes mellitus or juvenile diabetes, is a form of diabetes mellitus that results from autoimmune destruction of insulin-producing beta cells of the pancreas. The subsequent lack of insulin leads to increased blood glucose concentrations and increased urinary glucose excretion. The classical symptoms are polyuria, polydipsia, polyphagia, and weight loss. Type 1 diabetes may be fatal unless treated with insulin. Complications from type 1 diabetes are the same or similar to complications from type 2 diabetes.

Large randomized studies have established that intensive and tight glycemic control during early (newly diagnoses to 5 years) stage diabetes has enduring beneficial effects and reduces the risk of diabetic complications, both micro- and macrovascular. However, many patients with diabetes still develop diabetic complications despite receiving intensified glycemic control.

Epidemiological and prospective data support a long-term influence of early (newly diagnosed to 5 years) metabolic control on clinical outcomes. It has been found that hyperglycemia has long-lasting deleterious effects both in type 1 and type 2 diabetes and that glycemic control, if not started at a very early stage of the disease or not intensively or not tightly provided, may not be enough to completely reduce complications.

It has been further found that transient episodes of hyperglycemia (e.g. hyperglycemic events), can induce molecular changes, and that these changes can persist or are irreversible after return to normoglycemia.

Collectively, these data suggest that metabolic memories are stored early in the course of diabetes and that, in certain diabetic conditions, oxidative and/or vascular stresses can persist after glucose normalization. This phenomenon that early glycemic environment, and/or even transient hyperglycemia, is remembered with clinical consequences in the target end organs (e.g. blood vessels, retina, kidney, heart, extremities) has recently been termed as ‘metabolic memory.’

Potential mechanisms for propagating this ‘memory’ are certain epigenetic changes, the nonenzymatic glycation of cellular proteins and lipids (e.g. formation of advanced glycation endproducts), oxidatively modified atherogenic lipoproteins, and/or an excess of cellular reactive oxygen and nitrogen species (RONS), in particular originated at the level of glycatedmitochondrial proteins, perhaps acting in concert with one another to maintain stress signalling.

02831903\l-01

Mitochondria are one of major sources of reactive oxygen species (ROS) in cells. Mitochondrial dysfunction increases electron leak and the generation of ROS from the mitochondrial respiratory chain (MRC). High levels of glucose and lipids impair the activities of MRC complex enzymes. For example, the MRC enzyme NADPH oxidase generates superoxide from NADPH in cells. Increased NADPH oxidase activity can be detected in diabetic patients.

Further, there is evidence that overproduction of free radicals, such as e.g. reactive oxygen species (ROS), contributes to oxidative and vascular stress after glucose normalization and to developing and/or maintaining the metabolic memory, and thus to the unifying link between hyperglycemia and cellular memory effects, such as e.g. in endothelial dysfunction or other complications of diabetes.

Thus, mainly related to persisting (long-term) oxidative stress induced by or associated with (chronic, early or transient episodes of) hyperglycemia, there are certain metabolic conditions in that, even normalizing glycemia, a long-term persitent activation of many pathways involved in the pathogenesis of diabetic complications can still be present. One of the major findings in the course of diabetes has thereby been the demonstration that even in normoglycemia and independent of the actual glycemic levels an overproduction of free radicals can still be evident. For example, endothelial dysfunction (a causative marker of diabetic vascular complications) can persist even after normalizing glycemia. However, there is evidence that combining antioxidant therapy with normalization of glycemia can be used to almost interrupt endothelial dysfunction.

Therefore, treating oxidative and/or vascular stress particularly beyond glycemic control, such as by the reduction of cellular reactive species and/or of glycation (e.g. by inhibition of the production of free oxygen and nitrogen radicals), preferably independently of glycemic status, may beneficially modulate, reduce, block or protect against the memory’ effect of hyperglycemia and reduce the risk, prevent, treat or delay the onset of long-term diabetic complications, particularly such ones which are associated with or induced by oxidative stress, in patients in need thereof.

Standard therapy of type 1 diabetes is insulin treatment. Therapies for type 1 diabetes are for example described in WO 2012/062698.

The treatment of type 2 diabetes typically begins with diet and exercise, followed by oral antidiabetic monotherapy, and although conventional monotherapy may initially control blood glucose in some patients, it is however associated with a high secondary failure rate. The limitations of single-agent therapy for maintaining glycemic control may be overcome, at least

02831903\l-01 in some patients, and for a limited period of time by combining multiple drugs to achieve reductions in blood glucose that cannot be sustained during long-term therapy with single agents. Available data support the conclusion that in most patients with type 2 diabetes current monotherapy will fail and treatment with multiple drugs will be required.

But, because type 2 diabetes is a progressive disease, even patients with good initial responses to conventional combination therapy will eventually require an increase of the dosage or further treatment with insulin because the blood glucose level is very difficult to maintain stable for a long period of time. Although existing combination therapy has the potential to enhance glycemic control, it is not without limitations (especially with regard to long term efficacy). Further, traditional therapies may show an increased risk for side effects, such as hypoglycemia or weight gain, which may compromise their efficacy and acceptability.

Thus, for many patients, these existing drug therapies result in progressive deterioriation in metabolic control despite treatment and do not sufficiently control metabolic status especially over long-term and thus fail to achieve and to maintain glycemic control in advanced or late stage type 2 diabetes, including diabetes with inadequate glycemic control despite conventional oral or non-oral antidiabetic medication.

Therefore, although intensive treatment of hyperglycemia can reduce the incidence of chronic damages, many patients with type 2 diabetes remain inadequately treated, partly because of limitations in long term efficacy, tolerability and dosing inconvenience of conventional antihyperglycemic therapies.

This high incidence of therapeutic failure is a major contributor to the high rate of long-term hyperglycemia-associated complications or chronic damages (including micro- and makrovascular complications such as e.g. diabetic nephrophathy, retinopathy or neuropathy, or cardiovascular complications such as e.g. myocardial infarction, stroke or vascular mortality or morbidity) in patients with type 2 diabetes.

Oral antidiabetic drugs conventionally used in therapy (such as e.g. first- or second-line, and/or mono- or (initial or add-on) combination therapy) include, without being restricted thereto, metformin, sulphonylureas, thiazolidinediones, DPP-4 inhibitors, glinides and aglucosidase inhibitors.

Non-oral (typically injected) antidiabetic drugs conventionally used in therapy (such as e.g. first- or second-line, and/or mono- or (initial or add-on) combination therapy) include, without being restricted thereto, GLP-1 or GLP-1 analogues, and insulin or insulin analogues.

However, the use of these conventional antidiabetic or antihyperglycemic agents can be associated with various adverse effects. For example, metformin can be associated with lactic acidosis or gastrointestinal side effects; sulfonylureas, glinides and insulin or insulin analogues can be associated with hypoglycemia and weight gain; thiazolidinediones can be associated with edema, bone fracture, weight gain and heart failure/cardiac effects; and alpha-glucosidase blockers and GLP-1 or GLP-1 analogues can be associated with gastrointestinal adverse effects (e.g. dyspepsia, flatulence or diarrhea, or nausea or vomiting) and, most seriously (but rare), pancreatitis.

Therefore, it remains a need in the art to provide efficacious, safe and tolerable antidiabetic therapies.

Further, within the therapy of type 2 diabetes, it is a need for treating the condition effectively, avoiding the complications inherent to the condition, and delaying disease progression, e.g. in order to achieve a long-lasting therapeutic benefit.

Furthermore, it remains a need that antidiabetic treatments not only prevent the long-term Moreover, it remains a need to provide prevention or reduction of risk for adverse effects associated with conventional antidiabetic therapies.

SGLT2 inhibitors (sodium-glucose co-transporter 2) represent a novel class of agents that are being developed for the treatment or improvement in glycemic control in patients with type 2 diabetes. Glucopyranosyl-substituted benzene derivative are described as SGLT2 inhibitors, for example in WO 01/27128, WO 03/099836, WO 2005/092877, WO 2006/034489, WO 2006/064033, WO 2006/117359, WO 2006/117360, WO 2007/025943, WO 2007/028814, WO 2007/031548, WO 2007/093610, WO 2007/128749, WO 2008/049923, WO 2008/055870, WO 2008/055940. The glucopyranosyl-substituted benzene derivatives are proposed as inducers of urinary sugar excretion and as medicaments in the treatment of diabetes.

Renal filtration and reuptake of glucose contributes, among other mechanisms, to the steady state plasma glucose concentration and can therefore serve as an antidiabetic target. Reuptake of filtered glucose across epithelial cells of the kidney proceeds via sodiumdependent glucose cotransporters (SGLTs) located in the brush-border membranes in the tubuli along the sodium gradient. There are at least 3 SGLT isoforms that differ in their expression pattern as well as in their physico-chemical properties. SGLT2 is exclusively

02831903\l-01 expressed in the kidney, whereas SGLT1 is expressed additionally in other tissues like intestine, colon, skeletal and cardiac muscle. SGLT3 has been found to be a glucose sensor in interstitial cells of the intestine without any transport function. Potentially, other related, but not yet characterized genes, may contribute further to renal glucose reuptake. Under normoglycemia, glucose is completely reabsorbed by SGLTs in the kidney, whereas the reuptake capacity of the kidney is saturated at glucose concentrations higher than 10mM, resulting in glucosuria (“diabetes mellitus”). This threshold concentration can be decreased by SGLT2-inhibition. It has been shown in experiments with the SGLT inhibitor phlorizin that SGLT-inhibition will partially inhibit the reuptake of glucose from the glomerular filtrate into the blood leading to a decrease in blood glucose concentration and to glucosuria.

Empagliflozin is a novel SGLT2 inhibitor that is described for the treatment or improvement in glycemic control in patients with type 2 diabetes mellitus, for example in WO 05/092877, WO 06/117359, WO 06/120208, WO 2010/092126, WO 2010/092123, WO 2011/039107, WO 2011/039108.

said method comprising administering a therapeutically effective amount of the SGLT-2 inhibitor, optionally in combination with one or more other therapeutic substances, to the patient.

In a further aspect, the present invention relates to a certain SGLT-2 inhibitor for use in a method of reducing arterial stiffness in a patient. In one aspect, the patient is a patient according to the present invention, in particular a patient with type 1 or type 2 diabetes or pre-diabetes. Increased arterial stiffness is associated with an increased risk of cardiovascular events and the effect of empagliflozin on arterial stiffness is for example shown in the Examples hereinbelow.

The present invention further relates to a pharmaceutical composition comprising a certain SGLT-2 inhibitor as defined herein, empagliflozin, for use in the therapies described herein.

When this invention refers to patients requiring treatment or prevention, it relates primarily to treatment and prevention in humans, but the pharmaceutical composition may also be used accordingly in veterinary medicine in mammals. In the scope of this invention adult patients are preferably humans of the age of 18 years or older. Also in the scope of this invention, patients are adolescent humans, i.e. humans of age 10 to 17 years, preferably of age 13 to 17 years. It is assumed that in a adolescent population the administration of the pharmaceutical composition according to the invention a very good HbAlc lowering and a very good lowering of the fasting plasma glucose can be seen. In addition it is assumed that in an adolescent population, in particular in overweight and/or obese patients, a pronounced weight loss can be observed.

As described hereinbefore by the administration of the pharmaceutical composition according to this invention and in particular in view of the high SGLT2 inhibitory activity of the

02831903\l-01

SGLT2 inhibitors therein, excessive blood glucose is excreted through the urine of the patient, so that no gain in weight or even a reduction in body weight may result. Therefore, a treatment or prophylaxis according to this invention is advantageously suitable in those patients in need of such treatment or prophylaxis who are diagnosed of one or more of the conditions selected from the group consisting of overweight and obesity, in particular class I obesity, class II obesity, class III obesity, visceral obesity and abdominal obesity. In addition a treatment or prophylaxis according to this invention is advantageously suitable in those patients in which a weight increase is contraindicated. The pharmaceutical composition as well as the methods according to the present invention allow a reduction of the HbA1c value to a desired target range, for example &lt; 7 % and preferably &lt; 6.5 %, for a higher number of patients and for a longer time of therapeutic treatment compared with a corresponding monotherapy or a therapy using only two of the combination partners.

The pharmaceutical composition according to this invention and in particular the SGLT2 inhibitor therein exhibits a very good efficacy with regard to glycemic control, in particular in view of a reduction of fasting plasma glucose, postprandial plasma glucose and/or glycosylated hemoglobin (HbA1c). By administering a pharmaceutical composition according to this invention, a reduction of HbA1c equal to or greater than preferably 0.5 %, even more preferably equal to or greater than 1.0 % can be achieved and the reduction is particularly in the range from 1.0 % to 2.0 %.

Furthermore, the method and/or use according to this invention is advantageously applicable in those patients who show one, two or more of the following conditions:

(a) a fasting blood glucose or serum glucose concentration greater than 100 mg/dL, in particular greater than 125 mg/dL;

(b) a postprandial plasma glucose equal to or greater than 140 mg/dL;

(c) an HbA1c value equal to or greater than 6.5 %, in particular equal to or greater than 7.0 %, especially equal to or greater than 7.5 %, even more particularly equal to or greater than 8.0 %.

The present invention also discloses the use of the pharmaceutical composition for improving glycemic control in patients having type 1 or type 2 diabetes or showing first signs of pre-diabetes. Thus, the invention also includes diabetes prevention. If therefore a pharmaceutical composition according to this invention is used to improve the glycemic control as soon as one of the above-mentioned signs of pre-diabetes is present, the onset of manifest type 2 diabetes mellitus can be delayed or prevented.

02831903\l-01

Furthermore, the pharmaceutical composition according to this invention is particularly suitable in the treatment of patients with insulin dependency, i.e. in patients who are treated or otherwise would be treated or need treatment with an insulin or a derivative of insulin or a substitute of insulin or a formulation comprising an insulin or a derivative or substitute thereof. These patients include patients with diabetes type 2 and patients with diabetes type 1.

Therefore, according to a preferred embodiment of the present invention, there is provided a method for improving glycemic control and/or for reducing of fasting plasma glucose, of postprandial plasma glucose and/or of glycosylated hemoglobin HbA1c in a patient in need thereof who is diagnosed with impaired glucose tolerance (IGT), impaired fasting blood glucose (IFG) with insulin resistance, with metabolic syndrome and/or with type 2 or type 1 diabetes mellitus characterized in that an SGLT2 inhibitor as defined hereinbefore and hereinafter is administered to the patient.

According to another preferred embodiment of the present invention, there is provided a method for improving gycemic control in patients, in particular in adult patients, with type 2 diabetes mellitus as an adjunct to diet and exercise.

It can be found that by using a pharmaceutical composition according to this invention, an improvement of the glycemic control can be achieved even in those patients who have insufficient glycemic control in particular despite treatment with an antidiabetic drug, for example despite maximal recommended or tolerated dose of oral monotherapy with metformin. A maximal recommended dose with regard to metformin is for example 2000 mg per day or 850 mg three times a day or any equivalent thereof.

Therefore, the method and/or use according to this invention is advantageously applicable in those patients who show one, two or more of the following conditions:

(a) insufficient glycemic control with diet and exercise alone;

(b) insufficient glycemic control despite oral monotherapy with metformin, in particular despite oral monotherapy at a maximal tolerated dose of metformin;

(c) insufficient glycemic control despite oral monotherapy with another antidiabetic agent, in particular despite oral monotherapy at a maximal tolerated dose of the other antidiabetic agent.

The lowering of the blood glucose level by the administration of an SGLT2 inhibitor according to this invention is insulin-independent. Therefore, a pharmaceutical composition according

02831903\l-01 to this invention is particularly suitable in the treatment of patients who are diagnosed having one or more of the following conditions

- insulin resistance,

- hyperinsulinemia,

- pre-diabetes,

- type 2 diabetes mellitus, particular having a late stage type 2 diabetes mellitus, - type 1 diabetes mellitus.

Furthermore, a pharmaceutical composition according to this invention is particularly suitable in the treatment of patients who are diagnosed having one or more of the following conditions (a) obesity (including class I, II and/or III obesity), visceral obesity and/or abdominal obesity, (b) triglyceride blood level >150 mg/dL, (c) HDL-cholesterol blood level < 40 mg/dL in female patients and < 50 mg/dL in male patients, (d) a systolic blood pressure >130 mm Hg and a diastolic blood pressure > 85 mm Hg, (e) a fasting blood glucose level >100 mg/dL.

It is assumed that patients diagnosed with impaired glucose tolerance (IGT), impaired fasting blood glucose (IFG), with insulin resistance and/or with metabolic syndrome suffer from an increased risk of developing a cardiovascular disease, such as for example myocardial infarction, coronary heart disease, heart insufficiency, thromboembolic events. A glycemic control according to this invention may result in a reduction of the cardiovascular risks.

Furthermore, a pharmaceutical composition according to this invention is particularly suitable in the treatment of patients after organ transplantation, in particular those patients who are diagnosed having one or more of the following conditions (a) a higher age, in particular above 50 years, (b) male gender;

(c) overweight, obesity (including class I, II and/or III obesity), visceral obesity and/or abdominal obesity, (d) pre-transplant diabetes, (e) immunosuppression therapy.

Furthermore, a pharmaceutical composition according to this invention is particularly suitable in the treatment of patients who are diagnosed having one or more of the following conditions:

02831903\l-01 (a) hyponatremia, in particular chronical hyponatremia;

(b) water intoxication;

(c) water retention;

(d) plasma sodium concentration below 135 mmol/L.

The patient may be a diabetic or non-diabetic mammal, in particular human.

Furthermore, a pharmaceutical composition according to this invention is particularly suitable in the treatment of patients who are diagnosed having one or more of the following conditions:

(a) high serum uric acid levels, in particular greater than 6.0 mg/dL (357 pmol/L);

(b) a history of gouty arthritis, in particular recurrent gouty arthritis;

(c) kidney stones, in particular recurrent kidney stones; (d)a high propensity for kidney stone formation.

In certain embodiments, the patients which may be amenable to to the therapies of this invention may have or are at-risk of one or more of the following diseases, disorders or conditions: type 1 diabetes, type 2 diabetes, impaired glucose tolerance (IGT), impaired fasting blood glucose (IFG), hyperglycemia, postprandial hyperglycemia, postabsorptive hyperglycemia, latent autoimmune diabetes in adults (LADA), overweight, obesity, dyslipidemia, hyperlipidemia, hypercholesterolemia, hypertriglyceridemia, hyperNEFA-emia, postprandial lipemia, hypertension, atherosclerosis, endothelial dysfunction, osteoporosis, chronic systemic inflammation, non alcoholic fatty liver disease (NAFLD), polycystic ovarian syndrome, metabolic syndrome, nephropathy, micro- or macroalbuminuria, proteinuria, retinopathy, cataracts, neuropathy, learning or memory impairment, neurodegenerative or cognitive disorders, cardiovascular diseases, tissue ischaemia, diabetic foot or ulcus, atherosclerosis, hypertension, endothelial dysfunction, myocardial infarction, acute coronary syndrome, unstable angina pectoris, stable angina pectoris, peripheral arterial occlusive disease, cardiomyopathy (including e.g. uremic cardiomyopathy), heart failure, cardiac hypertrophy, heart rhythm disorders, vascular restenosis, stroke, (renal, cardiac, cerebral or hepatic) ischemia/reperfusion injuries, (renal, cardiac, cerebral or hepatic) fibrosis, (renal, cardiac, cerebral or hepatic) vascular remodeling; a diabetic disease, especially type 2 diabetes, mellitus may be preferred (e.g. as underlying disease).

In a further embodiment, the patients which may be amenable to to the therapies of this invention have a diabetic disease, especially type 2 diabetes mellitus, and may have or are at-risk of one or more other diseases, disorders or conditions, such as e.g. selected from those mentioned immediately above.

02831903\l-01

In further embodiments, the present invention also relates to the effect of certain SGLT-2 inhibitors, in particular empagliflozin, on beta-cells and/or on the function of beta-cells, for example in patients having latent autoimmune diabetes in adults (LADA).

Accordingly, in one embodiment, the present invention relates to certain SGLT-2 inhibitors, in particular empagliflozin, for use in preventing, slowing, delaying or treating the degeneration of pancreatic beta cells and/or the decline of the functionality of pancreatic beta cells and/or for improving and/or restoring the functionality of pancreatic beta cells and/or restoring the functionality of pancreatic insulin secretion in a patient having latent autoimmune diabetes in adults (LADA).

In a further embodiment, the present invention relates to certain SGLT-2 inhibitors, in particular empagliflozin, for use in preserving pancreatic beta cells and/or their function in a patient having latent autoimmune diabetes in adults (LADA).

In a further embodiment, the present invention relates to certain SGLT-2 inhibitors, in particular empagliflozin, for use in stimulating and/or protecting the functionality of pancreatic insulin secretion in a patient having latent autoimmune diabetes in adults (LADA).

Usually three criteria are needed fulfilled for diagnosis of LADA: 1) adult age at onset of diabetes (> 30 years), 2) the presence of circulating islet autoantibodies (markers of beta cell autoimmunity to distinguish LADA from T2DM, e.g. islet cell antibodies (ICA, against cytoplasmic proteins in the beta cell, islet-cell cytoplasm), antibodies to glutamic acid decarboxylase (GAD-65, antiGAD), insulin autoantibodies (IAA), and/or IA-2A antibodies to the intracytoplasmatic domain of the tyrosine phosphatase-like protein IA-2), and

3) lack of a requirement for insulin for at least 6 months after diagnosis (to distinguish LADA from classic T1 DM).

However, alternative definitions of LADA include GAD (glutamic acid decarboxylase) antibody titer > 0.08 U/mL and 1) lifestyle and oral therapy or 2) insulin treatment started later than 12 months after diagnosis or 3) insulin therapy started before 12 months after diagnosis, but with fasting C-peptide levels > 150 pmol/l.

02831903\l-01

C-peptide originates from proinsulin and is produced in the body along with insulin. It is an accepted biomarker for proof of beta-cell preservation. Persons with LADA typically have low, although sometimes moderate, levels of C-peptide as the disease progresses.

One prerequisite in the definition is the presence of one or more circulating autoantibodies. For this reasons it is sometimes argued that LADA is just a “low-titer T1 DM condition”. However, the LADA population often shares phenotypical traits with T2DM, more so than with T1 DM; therefore LADA etiologically may represent a unique disease entity that is characterized by a more rapid decline of β-cell function than common T2DM.

It has been demonstrated, in several studies, that insulin dependency occurs at higher rate in LADA than in subjects with common T2DM.

Accordingly, in one aspect, a patient having LADA according to the present invention is a patient in whom one or more autoantibodies selected from GAD (GAD-65, anti-GAD), ICA, IA-2A, ZnT8 (anti-ZnT8) and IAA are present, and in one aspect, in a method or use according to the present invention a patient having LADA is a patient in whom one or more autoantibodies selected from GAD (GAD-65, anti-GAD), ICA, IA-2A, ZnT8 (anti-ZnT8).

One assumes that the LADA prevalence in a general type 2 diabetes population is at least 510%. Moreover, adults with LADA are frequently initially misdiagnosed as having type 2 diabetes, based on age; not etiology. In a survey conducted by Australia’s Type 1 Diabetes Network, one third of all Australians with type 1 diabetes reported being initially misdiagnosed as having the more common type 2 diabetes mellitus.

Currently, there is no “gold standard” for LADA treatment or management. In general, the treatment of LADA should focus not only on controlling glycemia and preventing the onset of any complications, but also allow preservation of residual beta cell function. Insulin therapy in LADA is often efficacious; but might be of most benefit in patients with both a high titer of GAD (> 10 U/mL) and preserved insulin secretion (C-peptide > 10 ng/mL). This also seems to apply to thiazolidinediones (glitazones), in particular if combined with insulin when islet beta cell function is preserved. Sulfonylureas (SUs) (and glinides) have in some studies been shown to be detrimental on beta cell function in LADA. This is supported by that metabolic control by SUs when compared to insulin also is often less.

Accordingly, in a further embodiment, the present invention relates to certain SGLT-2 inhibitors, in particular empagliflozin, for use in treating and/or preventing LADA (latent autoimmune diabetes of adults), particularly in those patients having LADA in whom one or

02831903)1-01 more autoantibodies selected from GAD (GAD-65, anti-GAD), ICA, IA-2A, ZnT8 (anti-ZnT8) and IAA are present.

Within the scope of the present invention it has now been found that certain SGLT-2 inhibitors as defined herein, optionally in combination with one or more other therapeutic substances (e.g. selected from those described herein), as well as pharmaceutical combinations, compositions or combined uses according to this invention of such SGLT-2 inhibitors as defined herein have properties, which make them suitable for the purpose of this invention and/or for fulfilling one or more of above needs.

The effect of empagliflozin on cardiovascular diseases, in particular on the risk of a cardiovascular event, for example such as defined herein, is for example determined as described in the Examples hereinbelow.

The effect of empagliflozin on beta-cells and/or on the function of beta-cells is for example determined as described in the Examples hereinbelow.

The present invention thus relates to a certain SGLT-2 inhibitor as defined herein, preferably empagliflozin, for use in the therapies described herein.

Furthermore, it can be found that the administration of a pharmaceutical composition according to this invention results in no risk or in a low risk of hypoglycemia. Therefore, a treatment or prophylaxis according to this invention is also advantageously possible in those patients showing or having an increased risk for hypoglycemia.

A pharmaceutical composition according to this invention is particularly suitable in the long term treatment or prophylaxis of the diseases and/or conditions as described hereinbefore and hereinafter, in particular in the long term glycemic control in patients with type 2 diabetes mellitus.

The term long term as used hereinbefore and hereinafter indicates a treatment of or administration in a patient within a period of time longer than 12 weeks, preferably longer than 25 weeks, even more preferably longer than 1 year.

Therefore, a particularly preferred embodiment of the present invention provides a method for therapy, preferably oral therapy, for improvement, especially long term improvement, of glycemic control in patients with type 2 diabetes mellitus, especially in patients with late

02831903\l-01 stage type 2 diabetes mellitus, in particular in patients additionally diagnosed of overweight, obesity (including class I, class II and/or class III obesity), visceral obesity and/or abdominal obesity.

It will be appreciated that the amount of the pharmaceutical composition according to this invention to be administered to the patient and required for use in treatment or prophylaxis according to the present invention will vary with the route of administration, the nature and severity of the condition for which treatment or prophylaxis is required, the age, weight and condition of the patient, concomitant medication and will be ultimately at the discretion of the attendant physician. In general, however, the SGLT2 inhibitor according to this invention is included in the pharmaceutical composition or dosage form in an amount sufficient that by its administration the glycemic control in the patient to be treated is improved.

Examples

Example 1: Effects of SGLT2 inhibition on oxidative stress, vessel wall thickness and collagen content, and endothelial dysfunction in STZ-induced Diabetes mellitus (Type I) in rat.

Type I diabetes in Wistar rats (8 weeks old, 250-300 g) are induced by a single i.v. injection of STZ (60 mg/kg). The blood glucose level is measured 3 days after STZ injection (to test whether diabetes was induced) and on the day of sacrifice. One week after injection empagliflozin (SGLT2-i) was administered with drinking water for additional 7 weeks (10 and 30 mg/kg/d p.o.). Treatment with empagliflozin showed a distinct reduction of blood glucose levels in diabetic rats without influence on loss of weight gain. Isometric tension recordings showed an empagliflozin-dependent normalization of endothelial function in diabetic animals and reduced oxidative stress in aortic vessels and blood, examined by DHE staining of aortic cryosections and PDBu/zymosanA-stimulated chemiluminescence, respectively. Additionally, a tendency of increased NADPH-oxidase activity in heart and a significant reduction of ALDH-2 activity in the liver were observed in diabetic animals, reflecting oxidative stress diminution triggered by empagliflozin therapy. The results are shown in Figures 1-13.

Figure 1: Shows the effect of Empagliflozin on weight gain, blood glucose and glycated hemoglobin (HbA1C) at low dose (10mg/kg) and high dose (30mg/kg) given in drinking water.

Figure 2: A: Endothelial dependant vasorelaxation. This figure shows the improvement of endothelial function measured with isolated aortic rings after 7 weeks of treatment.

B: Endothelial independent vasorelaxation obtain with glyceryl trinitrate (GTN) a NO donor. This figure shows the capacity of all vessel walls to vasorelax independantly of the endothelium demonstrating the absence of deleterious effect of the treament on smooth muscle cells.

Figures 3-9: Quantification of reactive oxygen species of (ROS) from leukocyte upon stimulation with zymosan A (ZymA). After 7 weeks of treament, ROS production in blood is reduced either with the low or high dose of empagliflozin to level close to none diabetic animal.

Figure 10: Shows that the NADPH oxidase activity in the cardiac tissue, an important source of superoxide is diminished with empagliflozin treatment.

Figure 11: Shows that the reduction of ALDH-2 activity in diabetic STZ animal is partly restored with empagliflozin treatment.

02831903\l-01

Figure 12A and 12B: Shows that the superoxide formation in the vessels of diabetic animals is reduced. Figure 12A shows results with a partial set of animals, figure 12B shows results with all animals.

Figure 13A-D: Shows the level of plasmatic cholesterol, triglycerides, insulin and Interferon γ in STZ diabetic rats compared to normal rat and in diabetic rat treated with empagliflozin. While empagliflozin restore insulin level, the elevation of interferon γ (a marker of inflammation) in diabetic rats is highly diminished or supressed with empagliflozin treatment.

Aortic wall thickness and collagen content were also measured microscopically after sirius red staining. Aortic segments were fixed in parafomaldehyde (4%) and paraffin-embedded. Sirius red staining for vascular fibrosis was performed with paraffin-embedded samples of aortic tissue upon de-paraffination. Afterwards the nuclei were prestained with hemalum. Then samples were stained for 1 hour in 0.1% with Sirius red solution containing saturated picric acid (1.2%). Finally, tissue samples were dehydrated with 70%, 96% and 100% isopropanol and coverslipped with a solution of polymers in xylene. 60-70 measurements were made per sample, n=6-7 animals/groups. The results are shown in Figures 16A and 16B.

Figure 16A and 16B: Microscopic determination of aortic wall thickness and collagen content by sirius red staining of aortic paraffinated sections. Quantification (figure 16A) and representative microscope images (figure 16B). Aortic wall thickness and collagen content was slightly increased in diabetic rats and was normalized by empagliflozin treatment.

Example 2: Measurement of hourly blood pressure.

Empagliflozin (10 mg and 25 mg) was administered orally once daily over 12 weeks in hypertensive patients with type 2 diabetes mellitus. The change from baseline in hourly mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) was measured over a 24hour period afer 12 weeks of treatment compared to the placebo group and is shown in Figures 14 and 15.

Example 3: Treatment of patients with type 2 diabetes mellitus with elevated cardiovascular risk.

Example 4: Treatment of type 2 diabetes mellitus

Treating patients with type 2 diabetes mellitus with empagliflozin, in addition to producing an acute improvement in the glucose metabolic situation, prevents a deterioration in the metabolic situation in the long term. This can be observed is patients are treated for a longer period, e.g. 3 months to 1 year or even 1 to 6 years, with a combination according to the invention and are compared with patients who have been treated with other antidiabetic and/ or antiobesity medicaments. There is evidence of therapeutic success compared with other treatments if no or only a slight increase in the fasting glucose and/or HbA1c value is observed. Further evidence of therapeutic success is obtained if a significantly smaller percentage of the patients treated with a combination according to the invention, compared with patients who have received another treatment, undergo a deterioration in the glucose metabolic position (e.g. an increase in the HbA1c value to >6.5% or >7%) to the point where treatment with an (additional) oral antidiabetic medicament or with insulin or with an insulin analogue is indicated.

Example 5: Treatment of insulin resistance

In clinical studies running for different lengths of time (e.g. 2 weeks to 12 months) the success of the treatment is checked using a hyperinsulinaemic euglycaemic glucose clamp study. A significant rise in the glucose infusion rate at the end of the study, compared with the initial value or compared with a placebo group, or a group given a different therapy, proves the efficacy of a treatment according to the invention in the treatment of insulin resistance.

Example 6: Treatment of hyperglycaemia

In clinical studies running for different lengths of time (e.g. 1 day to 24 months) the success of the treatment in patients with hyperglycaemia is checked by determining the fasting glucose or non-fasting glucose (e.g. after a meal or a loading test with 0GTT or a defined meal). A significant fall in these glucose values during or at the end of the study, compared with the initial value or compared with a placebo group, or a group given a different therapy, proves the efficacy of a combination treatment according to the invention in the treatment of hyperglycaemia.

Example 7: Effect of empagliflozin versus glimepiride on beta-cell function

02831903\l-01

In a Phase III study the effects of empagliflozin and the SU glimepiride as second-line therapy are compared in patients with T2DM inadequately controlled with metformin immediate release (IR) and diet/exercise.

After a 2-week placebo run-in, patients are randomized to receive empagliflozin 25 mg once daily (qd) or glimepiride 1-4 mg qd double-blind for 104 weeks, in addition to metformin IR. Patients who participate in the initial 104-weeks randomization period will be eligible for a 104-week double-blind extension.

The primary endpoint is change from baseline in HbA1c. Secondary endpoints are change from baseline in body weight, the incidence of confirmed hypoglycemia, and changes in systolic and diastolic blood pressure. Exploratory endpoints include change from baseline in FPG, the proportion of patients achieving HbA1c &lt;7%, and effects on various biomarkers of beta-cell function including insulin, C-peptide, HOMA-B and proinsulin to insulin ratio, first and second phase insulin secretion after a meal tolerance test.

In addition, primary, secondary and exploratory endpoints are evaluated in a sub-group of patients with Latent Autoimmune Diabetes in Adulthood (LADA), identified by the presence at baseline of autoantibodies against insulin, islet cell cytoplasm, glutamic acid decarboxylase 65 or the intracytoplasmic domain of the tyrosine phosphatase-like protein IA-2.

Example 8: Effect of empagliflozin arterial stiffness

Blood pressure, arterial stiffness, heart rate variability (HRV) and circulating adrenergic mediators were measured during clamped euglycemia and hyperglycemia in 40 normotensive patients with T1D. Studies were repeated after 8 weeks of empagliflozin (25 mg daily).

Augmentation index (Alx) for the radial and carotid arteries as well as a derived aortic Alx and carotid, radial and femoral pulse wave velocities (PWV) are measured for assessment of arterial stiffness using a SphygmoCor® System (AtCor Medical Inc., Itasca, IL).

During clamped euglycemic conditions, empagliflozin reduced systolic blood pressure (111±9 to 109±9 mmHg, p=0.0187), and augmentation indices at the radial (-52±16 to -57±17%, p&lt;0.0001), carotid (+1.3±17.0 to -5.7±17.0%, p&lt;0.0001) and aortic positions (+0.1±13.4 to 6.2±14.3%, p&lt;0.0001) declined. Similar effects on arterial stiffness were observed during clamped hyperglycemia; however, blood pressure effects were not significant. Carotid-radial pulse wave velocity decreased significantly under both glycemic conditions (p&lt;0.0001), while declines in carotid-femoral pulse wave velocity were only significant during clamped hyperglycemia (5.7±1.1 to 5.2±0.9 m/s, p=0.0017). HRV, plasma noradrenaline and adrenaline remained unchanged under both glycemic conditions.

This shows that empagliflozin reduces arterial stiffness in patients with uncomplicated T1D.
