The present invention relates to certain SGLT-2 inhibitors for treating, preventing, protecting against and/or delaying the progression of chronic kidney disease in patients, for example patients with prediabetes, type 1 or type 2 diabetes mellitus.
Chronic kidney disease (CKD), also known as chronic renal disease, is a progressive loss in renal function over a period of months or years. The symptoms of worsening kidney function are non-specific, and chronic kidney disease is often diagnosed as a result of screening of people known to be at risk of kidney problems.
Chronic kidney disease may be identified by a blood test, for example for creatinine. Higher levels of creatinine indicate a lower glomerular filtration rate and as a result a decreased capability of the kidneys to excrete waste products.
CKD has been classified into 5 stages, where stage 1 is kidney damage with normal GFR (mL/min/1.73 m2) of ≥90; stage 2 is kidney damage with a mild decrease in GFR (GFR 60-89); stage 3 is a moderate decrease in GFR (GFR 30-59); stage 4 is a severe decrease in GFR (GFR 15-29); and stage 5 is kidney failure (GFR <15 or dialysis). Stage 5 CKD is often called End Stage Renal Disease (ESRD) and is synonymous with the now outdated terms chronic kidney failure (CKF) or chronic renal failure (CRF).
Albuminuria can also be a sign of kidney disease. Albuminuria has been classified into 3 categories, where category A1 reflects no albuminuria with albumin normal to mildly increased; category A2 which reflects microalbuminuria with albumin moderately increased; category A3 which reflects macroalbuminuria with albumin severely increased.
There is no specific treatment unequivocally shown to slow the worsening of chronic kidney disease and severe CKD requires renal replacement therapy, which may involve a form of dialysis, but ideally constitutes a kidney transplant.
Therefore, there is an unmet medical need for methods, medicaments and pharmaceutical compositions able to slow the worsening or progression of chronic kidney disease in patients, in particular patients at risk of renal diseases, for example patients with prediabetes, type 1 or type 2 diabetes mellitus.

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.
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).
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 E S, 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.
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 (μU/mL)]×[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 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, et al. 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 HOMA-index for beta-cell function (Matthews et al., Diabetologia 1985, 28: 412-19), the ratio of intact proinsulin to insulin (Forst et al., Diabetes 2003, 52(Suppl. 1): A459), 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., Eur J Clin Invest 2001, 31: 380-81).
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, INS 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 “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. <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 HbA1c 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 <7% or <6.5% and preferably <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 Del., et al. Am J Epidemiol 2002; 156:1070-7). According to the ATP III/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:
The NCEP definitions have been validated (Laaksonen Del., 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 diagnosed with 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 “chronic kidney disease (CDK)” is defined as abnormalities of kidney structure or function, present for more than three months, with implications for health. CKD is classified based on cause, GFR category, and albuminuria category (CGA).
CKD has been classified into 5 stages, where stage 1 is kidney damage with normal GFR (mL/min/1.73 m2) of 90 or above; stage 2 is kidney damage with a mild decrease in GFR (GFR 60-89); stage 3 is a moderate decrease in GFR (GFR 30-59); stage 4 is a severe decrease in GFR (GFR 15-29); and stage 5 is kidney failure (GFR <15 or dialysis). Stage 3 has been subdivided into stage 3A, which is a mild to moderate decrease in GFR (GFR 45-59), and stage 3B, which is a moderate to severe decrease in GFR (GFR 30-44).
The term “glomerular filtration rate (GFR)” is defined as the volume of fluid filtered from the renal (kidney) glomerular capillaries into the Bowman's capsule per unit time. It is indicative of overall kidney function. The glomerular filtration rate (GFR) can be calculated by measuring any chemical that has a steady level in the blood, and is freely filtered but neither reabsorbed nor secreted by the kidneys. The rate therefore measured is the quantity of the substance in the urine that originated from a calculable volume of blood. The GFR is typically recorded in units of volume per time, e.g., milliliters per minute and the formula below can be used:
GFR=(Urine Concentration×Urine Volume)/Plasma Concentration
The GFR can be determined by injecting inulin into the plasma. Since inulin is neither reabsorbed nor secreted by the kidney after glomerular filtration, its rate of excretion is directly proportional to the rate of filtration of water and solutes across the glomerular filter. A normal value is: GFR=90-125 mL/min/1.73 m2, in particular GFR=100-125 mL/min/1.73 m2.
Other principles to determine GFR involve measuring 51Cr-EDTA, [125I]iothalamate or iohexol.
The “estimated glomerular filtration rate (eGFR)” is defined as derived at screening from serum creatinine values based on e.g., the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation, the Cockcroft-Gault formula or the Modification of Diet in Renal Disease (MDRD) formula, which are all known in the art.
The term “albuminuria” is defined as a condition wherein more than the normal amount of albumin is present in the urine. Albuminuria can be determined by the albumin excretion rate (AER) and/or the albumin-to-creatine ratio (ACR) in the urine (also refered to as UACR).
Albuminuria categories in CKD are defined as follows:
Category A1 reflects no albuminuria, category A2 reflects microalbuminuria, category A3 reflects macroalbuminuria. The progression of category A1 usually leads to microalbuminuria (A2) but may also directly result in macroalbuminuria (A3). Progression of microalbuminuria (A2) results in macroalbuminuria (A3).
The term “empagliflozin” refers to the SGLT2 inhibitor 1-chloro-4-(1-D-glucopyranos-1-yl)-2-[4-((S)-tetrahydrofuran-3-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 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.

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 sodium-dependent 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 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 10 mM, 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.

Chronic kidney disease (CKD), also known as chronic renal disease, is a progressive loss in renal function over a period of months or years. Patients with renal disease, renal dysfunction or renal impairment may include patients with chronic renal insufficiency or impairment, which can be stratified (if not otherwise noted) according to glomerular filtration rate (GFR, ml/min/1.73 m2) into 5 disease stages: stage 1 characterized by normal GFR ≥90 plus either persistent albuminuria (e.g. UACR ≥30 mg/g) or known structural or hereditary renal disease; stage 2 characterized by mild reduction of GFR (GFR 60-89) describing mild renal impairment; stage 3 characterized by moderate reduction of GFR (GFR 30-59) describing moderate renal impairment; stage 4 characterized by severe reduction of GFR (GFR 15-29) describing severe renal impairment; and terminal stage 5 characterized by requiring dialysis or GFR <15 describing established kidney failure (end-stage renal disease, ESRD).
Chronic kidney disease and its stages (CKD 1-5) can be usually characterized or classified accordingly, such as based on the presence of either kidney damage (albuminuria) or impaired estimated glomerular filtration rate (GFR <60 [ml/min/1.73 m2], with or without kidney damage).
For the purpose of the present invention, the estimated glomerular filtration rate (eGFR) is derived from the serum creatinine (SCr) value based on the MDRD formula below:
eGFR (mL/min/1.73m2)=175×[SCr (μmol/L)/88.4]−1.154×[age]−0.203×[0.742 if patient is female]×[1.212 if patient is of African origin]
For additional analyses, renal function can also be classified by the estimated creatinine clearance rate (eCCr) value, based on the Cockcroft-Gault formula below:
eCCr (mL/min)=(140−age)×(weight in kg)×[0.85 if patient is female]/(72×SCr (mg/dL))
Renal function classification based on eCCr is similar to the eGFR classification: normal renal function (≥90 mL/min), mild impairment (60 to <90 mL/min), moderate impairment (30 to <60 mL/min), and severe impairment (≥15 to <30 mL/min).
Generally, mild renal impairment according to the present invention corresponds to stage 2 chronic kidney disease, moderate renal impairment according to the present invention generally corresponds to stage 3 chronic kidney disease, and severe renal impairment according to the present invention generally corresponds to stage 4 chronic kidney disease. Likewise, moderate A renal impairment according to the present invention generally corresponds to stage 3A chronic kidney disease and moderate B renal impairment according to the present invention generally corresponds to stage 3B chronic kidney disease.
Accordingly, in one aspect, the present invention relates to certain SGLT-2 inhibitors, for example empagliflozin, for use in treating, preventing, protecting against or delaying the progression of chronic kidney disease in a patient, in particular a patient according to the present invention, for example the progression from stage 1 chronic kidney disease to stage 2 chronic kidney disease, for example the progression from stage 2 chronic kidney disease to stage 3 chronic kidney disease, for example the progression from stage 3 chronic kidney disease to stage 4 chronic kidney disease, for example the progression from stage 4 chronic kidney disease to stage 5 chronic kidney disease.
In a further aspect of the present invention, the progression of chronic kidney disease in a patient is for example the progression from stage 2 chronic kidney disease to stage 3A chronic kidney disease, for example the progression from stage 3A chronic kidney disease to stage 3B chronic kidney disease, for example the progression from stage 3B chronic kidney disease to stage 4 chronic kidney disease.
In a further aspect of the present invention, the progression of chronic kidney disease in a patient is for example the progression from stage 2 chronic kidney disease to stage 4 or 5 chronic kidney disease, for example the progression from stage 3 chronic kidney disease to stage 5 chronic kidney disease, for example the progression from stage 3A or 3B chronic kidney disease to stage 5 chronic kidney disease.
In a further aspect, a patient with chronic kidney disease according to the present invention is a patient with stage 1 chronic kidney disease, stage 2 chronic kidney disease, stage 3 chronic kidney disease, stage 4 chronic kidney disease, or stage 5 chronic kidney disease. In a further aspect, a patient with chronic kidney disease according to the present invention is a patient with stage 3A chronic kidney disease or stage 3B chronic kidney disease,
In some aspects, renal disease, renal dysfunction, or insufficiency or impairment of renal function (including mild, moderate and/or severe renal impairment) may also be suggested (if not otherwise noted) by elevated serum creatinine levels (e.g. serum creatinine levels above the upper limit of normal for their age, e.g. ≥130-150 μmol/l, or ≥1.5 mg/dl (≥136 μmol/l) in men and ≥1.4 mg/dl (≥124 μmol/l) in women) or abnormal creatinine clearance (e.g. glomerular filtration rate (GFR) ≤30-60 ml/min).
In some further aspects, mild renal impairment may be also suggested (if not otherwise noted) by a creatinine clearance of 50-80 ml/min (approximately corresponding to serum creatine levels of ≤1.7 mg/dL in men and ≤1.5 mg/dL in women); moderate renal impairment may be e.g. suggested (if not otherwise noted) by a creatinine clearance of 30-50 ml/min (approximately corresponding to serum creatinine levels of >1.7 to ≤3.0 mg/dL in men and >1.5 to ≤2.5 mg/dL in women); and severe renal impairment may be e.g. suggested (if not otherwise noted) by a creatinine clearance of <30 ml/min (approximately corresponding to serum creatinine levels of >3.0 mg/dL in men and >2.5 mg/dL in women). Patients with end-stage renal disease require dialysis (e.g. hemodialysis or peritoneal dialysis).
In some further aspects, albuminuria can also be a sign of kidney disease. Albuminuria stages may be classified as disclosed herein, and patients may be stratified in category A1, which reflects no albuminuria, category A2, which reflects microalbuminuria, and category A3, which reflects macroalbuminuria.
Accordingly, in a further aspect, a patient with chronic kidney disease according to the present invention is a patient with microalbuminuria or with macroalbuminuria.
In one aspect of the present invention, it has been found that empagliflozin has nephroprotective properties, in particular as described herein. In particular, it has been shown that administration of empagliflozin has the property to maintain or improve renal function over time in certain patient group, for example as described herein, as demonstrated after discontinuation of administration of empagliflozin.
In one aspect, a patient in the context of the present invention is a patient at risk of renal disease. A patient at risk of renal disease is for example a patient with at least one of the following:
In one aspect, a patient in the context of the present invention is a patient with prediabetes, type 1 or 2 diabetes mellitus.
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 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.
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 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.
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 α-glucosidase 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.
The SGLT2 inhibitor therein also 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%.

Thus, in an embodiment, the therapies described herein may be used in naïve patients. In another embodiment, diabetes patients within the meaning of this invention may include patients with advanced or late stage type 2 diabetes mellitus (including patients with failure to conventional antidiabetic therapy), such as e.g. patients with inadequate glycemic control on one, two or more conventional oral and/or non-oral antidiabetic drugs as defined herein, such as e.g. patients with insufficient glycemic control despite (mono-)therapy with metformin, a thiazolidinedione (particularly pioglitazone), a sulphonylurea, a glinide, a DPP-4 inhibitor, GLP-1 or GLP-1 analogue, insulin or insulin analogue, or an α-glucosidase inhibitor, or despite dual combination therapy with metformin/sulphonylurea, metformin/thiazolidinedione (particularly pioglitazone), metformin/DPP-4 inhibitor, sulphonylurea/α-glucosidase inhibitor, pioglitazone/sulphonylurea, metformin/insulin, pioglitazone/insulin or sulphonylurea/insulin.
In one embodiment, a patient according to the present invention is a patient receiving treatment with a non-oral antidiabetic drug, for example GLP1-analog (for example short acting GLP-1 analog such as exenatide, liraglutide or lixisenatide, or long-acting GLP-1 analog such as exenatide extended-release, albiglutide or dulaglutide), for example insulin or insulin analogue, for example basal insulin, such as glargine, detemir and/or NPH insulin.
In one embodiment, a patient according to the present invention is a patient receiving treatment with insulin or insulin analogue. An insulin or insulin analogue may include normal insulin, human insulin, insulin derivatives, zinc insulins and insulin analogues, including formulations thereof with modified release profiles, in particular as used in the therapy of humans. The insulin may be selected from the group consisting of:
and mixtures thereof.
Mixtures of insulins may comprise mixtures of short- or rapid-acting insulins with long-acting insulins. For example such mixtures are marketed as Actraphane/Mixtard or Novomix.
The term “insulin” in the scope of the present invention covers insulins as described hereinbefore and hereinafter which are administered to the patient via injection, preferably subcutaneous injection, via infusion, including pumps, via inhalation or other routes of administration. Insulins to be administered via inhalation are for example Exubera (Pfizer), AIR (Lilly) and AER (Novo Nordisk).
Rapid-acting insulins usually start lowering the blood glucose within about 5 to 15 minutes and are effective for about 3 to 4 hours. Examples of rapid-acting insulins are insulin aspart, insulin lispro and insulin glulisine. Insulin Lispro is marketed under the trade name Humalog and Liprolog. Insulin Aspart is marketed under the trade names NovoLog and NovoRapid. Insulin glulisine is marketed under the trade name Apidra.
Short-acting insulins usually start lowering the blood glucose within about 30 minutes and are effective about 5 to 8 hours. An example is regular insulin or human insulin.
Intermediate-acting insulins usually start lowering the blood glucose within about 1 to 3 hours and are effective for about 16 to 24 hours. An example is NPH insulin, also known as Humulin N, Novolin N, Novolin NPH and isophane insulin. Another example are lente insulins, such as Semilente or Monotard.
Long-acting insulins usually start lowering the blood glucose within 1 to 6 hours and are effective for up to about 24 hours or even up to or beyond 32 hours. Long-acting insulin usually provides a continuous level of insulin activity (for up to 24-36 hours) and usually operates at a maximum strength (with flat action profile) after about 8-12 hours, sometimes longer. Long-acting insulin is usually administered in the morning or before bed. Examples of long-acting insulin may include, but are not limited to, insulin glargine, insulin detemir or insulin degludec, which are insulin analogues, and ultralente insulin, which is regular human insulin formulated for slow absorption. Long-acting insulin is suited to provide for basal, as opposed to prandial, insulin requirements (e.g. to control hyperglycemia). Long-acting insulin may be typically administered ranging from twice or once daily, over thrice weekly up to once weekly (ultra long-acting insulin). Insulin glargine is marketed under the trade name Lantus for example. Insulin detemir is marketed under the tradename Levemir for example.

Further embodiments, features and advantages of the present invention may become apparent from the following examples. The following examples serve to illustrate, by way of example, the principles of the invention without restricting it.
A Phase III trial investigated the efficacy and safety of empagliflozin (EMPA) as add-on to existing therapy for 52 weeks in patients with T2DM and RI. Patients with mild RI (eGFR [MDRD equation] ≥60 to <90 mL/min/1.73 m2) received EMPA 10 or 25 mg qd or placebo (PBO). Patients with moderate RI (eGFR ≥30 to <60 mL/min/1.73 m2) received EMPA 25 mg qd or PBO. Patients with severe RI (eGFR ≥15 to <30 mL/min/1.73 m2) received EMPA 25 mg qd or PBO.
In patients with type 2 diabetes and mild renal impairment, treatment with empagliflozin 10 and 25 mg at week 52 resulted in a small decrease in eGFR. However, mean eGFR increased to a value slightly above baseline at the 3-week follow up visit in the empagliflozin treatment groups; in contrast, in the placebo group, mean eGFR further decreased (Table 1A).
In patients with type 2 diabetes and moderate renal impairment, treatment with empagliflozin 25 mg at week 52 resulted a small decrease in eGFR while no change was seen for the placebo group. However, at the 3-week follow-up visit mean eGFR increased to a value slightly above baseline in the empagliflozin treatment group (Table 1B). Similar results were seen in patients with CKD 3A and B.
In patients with type 2 diabetes and severe renal impairment, treatment with empagliflozin 25 mg at week 52 resulted in a small decrease in eGFR. However, at the 3-week follow-up visit mean eGFR increased to a value slightly below baseline in the empagliflozin treatment group (Table 1C).
A Phase III trial investigated the efficacy and safety of empagliflozin (EMPA) administered orally, once daily over 12 weeks in hypertensive patients with T2DM (EMPA 10 or 25 mg, placebo (PBO)). Patients with a systolic blood pressure (SBP) of 130 to 159 mmHg and a diastolic blood pressure (DSP) of 80 to 99 mmHg were included in the trial.
Treatment with empagliflozin 10 and 25 mg at week 12 resulted in a small decrease in eGFR. However, mean eGFR increased to a value slightly above baseline at the 2-week follow up visit in the empagliflozin treatment groups; in contrast, in the placebo group, mean eGFR remained slightly below baseline (Table 2).
A Phase IIb trial investigated the efficacy and safety of empagliflozin (EMPA 10 or 25 mg, placebo (PBO)) administered orally, once daily over 78 weeks in patients with T2DM receiving treatment with basal insulin (glargine, detemir, or NPH insulin only).
Treatment with empagliflozin 10 and 25 mg resulted in a small decrease in eGFR. However, mean eGFR increased to a value slightly below baseline at the 4-week follow up visit in the empagliflozin treatment groups; in contrast, in the placebo group, mean eGFR further slightly decreased (Table 3).
1Percent of patient in population with values at this time point
In a dedicated 52 week renal impairment study, patients were categorised based on their urine albumin/creatinine ratio (UACR) values at baseline, and 3 categories of patients were distinguished: patients with normal urine albumin/creatinine ratio values (<30 mg/g), patients with microalbuminuria (30 to <300 mg/g) and patients with macroalbuminurea (≥300 mg/g). Differences in mean changes from baseline between the placebo and the empagliflozin treatment groups were noted for patients with microalbuminuria or macroalbuminuria at baseline. For patients with microalbuminuria, mean urine albumin/creatinine ratio values increased with placebo treatment, remained nearly unchanged with empagliflozin 10 mg treatment, and decreased with empagliflozin 25 mg treatment. In patients with macroalbuminuria at baseline, a decrease in mean urine albumin/creatinine ratio was noted only in the empagliflozin groups; (Table 4A).
Shifts between UACR categories at baseline and the end of treatment were noted in the randomised treatment groups (Table 4B). A higher frequency of patients in the empagliflozin treatment groups shifted from macro- or microalbuminura at baseline towards normal values and from macro- to microalbuminuria at the end of treatment. In addition, a higher proportion of patients in the placebo group shifted from normal values at baseline towards microalbuminuria at the end of treatment.
