`
`BACKGROUND OF THE INVENTION
`
`[0002] 1. Field of the Invention
`
`[0003] The specification describes the use of selected DPP
`IV inhibitors for the treatment of physiological functional
`disorders and for reducing the risk of the occurrence of such
`functional disorders in at-risk patient groups. In addition, the
`use of the above-mentioned DPP IV inhibitors in conjunc-
`tion with other active substances is described, by means of
`which improved treatment outcomes can be achieved. These
`applications may be used to prepare corresponding medica-
`ments.
`
`[0004] 2. Description of the Prior Art
`
`[0005] The enzyme DPP-IV, also known by the name
`CD26, is a serine protease which promotes the cleaving of
`dipeptides in proteins with a proline or alanine group at the
`N-terminal end. DPP-IV inhibitors thereby influence the
`plasma level of bioactive peptides including the peptide
`GLP-1 and are highly promising molecules for the treatment
`of diabetes mellitus.
`
`[0006] Type 1 diabetes mellitus, which occurs mainly in
`juveniles under 30 years of age, is categorised as an autoim-
`mune disease. With a corresponding genetic disposition and
`under the influence of various factors, insulitis occurs,
`followed by destruction of the B-cells, so that the pancreas
`is no longer able to produce much, if any, insulin.
`
`[0007] Type 2 diabetes mellitus is not categorised as an
`autoimmune disease and manifests itself in a fasting blood
`sugar level exceeding 125 mg of glucose per dl of plasma;
`the measurement of blood glucose values is a standard
`procedure in routine medical analysis. Prediabetes is sus-
`pected if the fasting blood sugar level exceeds the maximum
`normal level of 99 mg of glucose per dl of plasma but does
`not exceed the threshold of 125 mg of glucose per dl of
`plasma, which is relevant for diabetes. This is also referred
`to as pathological fasting glucose (impaired fasting glucose).
`Another indication of prediabetes is a disrupted glucose
`tolerance, i.e. a blood sugar level of 140-199 mg of glucose
`per dl of plasma 2 hours after taking 75 mg of glucose on an
`empty stomach within the scope of an oral glucose tolerance
`test.
`
`[0008]
`If a glucose tolerance test is carried out, the blood
`sugar level of a diabetic will be in excess of 199 mg of
`glucose per dl 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 will be between 60 and 99 mg per dl of plasma before
`taking the glucose, less than 200 mg per dl 1 hour after
`taking it and less than 140 mg per dl after 2 hours. If after
`2 hours the value is between 140 and 199 mg this is regarded
`as abnormal glucose tolerance or in some cases glucose
`intolerance.
`
`[0009] In the monitoring of the treatment of diabetes
`mellitus the HbAlc value, the product of a non-enzymatic
`
`glycation of the haemoglobin B chain, is of exceptional
`importance. As its formation depends essentially on the
`blood sugar level and the life time of the erythrocytes the
`HbAlc in the sense of a "blood sugar memory" reflects the
`average blood sugar level of the preceding 4-12 weeks.
`Diabetic patients whose HbAlc level has been well con-
`trolled over a long time by more intensive diabetes treatment
`(i.e. <6.5% of the total haemoglobin in the sample) are
`significantly better protected from diabetic microangiopa-
`thy. The available treatments for diabetes can give the
`diabetic an average improvement in their HbA1 c level of the
`order of 1.0-1.5%. This reduction in the HbAlc level is not
`sufficient in all diabetics to bring them into the desired target
`range of <6.5% and preferably <6% HbAlc.
`
`[0010] If insulin resistance can be detected this is a
`particularly strong indication of the presence of the complex
`metabolic disorder of prediabetes. Thus, it may be that in
`order to maintain glucose homoeostasis a person needs 2-3
`times as much insulin as another person. The most certain
`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 per-
`centile 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 concentra-
`tions in the blood are measured at fixed time intervals and
`from these the insulin resistance is calculated. Another
`method of measurement is the mathematical HOMA model.
`The insulin resistance is calculated by means of the fasting
`plasma glucose and the fasting insulin concentration. In this
`method it is not possible to distinguish between hepatic and
`peripheral insulin resistance. These processes are not really
`suitable for evaluating insulin resistance in daily practice. As
`a rule, other parameters are used in everyday clinical prac-
`tice 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.
`
`[0011] To simply somewhat, in practice it is assumed that
`people are insulin-resistant if they have at least 2 of the
`following characteristics:
`
`1) overweight or obesity
`
`2) high blood pressure
`
`3) dyslipidaemia (an altered content of total lipids in the
`blood)
`
`4) at least one close relative in whom abnormal glucose
`tolerance or type 2 diabetes has been diagnosed.
`
`[0012] Overweight means in this instance that the Body
`Mass Index (BMI) is between 25 and 30 kg/m2, the BMI
`being the quotient of the body weight in kg and the square
`of the height in metres. In manifest obesity the BMI is 30
`kg/m or more.
`
`[0013]
`It is immediately apparent, from the above defini-
`tion of insulin resistance, that hypotensive agents are suit-
`able and indicated for treating it if, among other things, high
`blood pressure is found in the patient.

`
`[0014] A similar indication of prediabetes is if the condi-
`tions for metabolic syndrome are met, the main feature of
`which is insulin resistance. According to the ATP IHINCEP
`Guidelines (Executive Summary of the Third Report of the
`National Cholesterol Education Program (NCEP) in the
`Journal of the American Medical Association 285:2486-
`2497, 2001) metabolic syndrome is present if a patient has
`at least 3 of the following characteristics:
`
`1) Abdominal obesity, defined as a waist measurement of
`>40 inches or 102 cm in men and >35 inches or 94 cm in
`women
`
`2) Triglyceride levels>150 mg/di
`
`3) HDL-cholesterol levels<40 mg/di in men
`
`4) High blood pressure>130/>85 mm Hg
`
`5) Fasting blood sugar of >110 mg/dl
`
`[0015] This definition of metabolic syndrome immediately
`shows that hypotensives are suitable for treating it if the
`patient is found to have high blood pressure, among other
`things.
`
`[0016] A triglyceride blood level of more than 150 mg/dl
`also indicates the presence of pre-diabetes. This suspicion is
`confirmed by a low blood level for HDL cholesterol. In
`women, levels below 55 mg per dl of plasma are regarded
`as too low while in men levels below 45 mg per dl of plasma
`are regarded as too low. 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 and Diagnose", TH-Books Verlagsgesell-
`schaft mbH, Frankfurt/Main, 2000. A suspicion of predia-
`betes is further confirmed if the fasting blood sugar levels
`also exceed 99 mg of glucose per dl of plasma.
`
`[0017] The term gestational diabetes (diabetes of preg-
`nancy) denotes a form of the sugar disease which develops
`during pregnancy and usually ceases again immediately
`after the birth. Gestational diabetes is diagnosed by a screen-
`ing test which is carried out between the 24th and 28th
`weeks of pregnancy. It is usually a simple test in which the
`blood sugar level is measured one hour after the adminis-
`tration of 50 g of glucose solution. If this 1 h level is above
`140 mg/dl, gestational diabetes is suspected. Final confir-
`mation may be obtained by a standard glucose tolerance test
`with 75 g of glucose.
`
`[0018] Hyperglycaemia describes a functional disorder in
`which an excessively high glucose level is measured in the
`blood, either in the fasting state (increased glucose level of
`100-125 mg/dl or diabetic-hyperglycaemic level of >125
`mg/dl compared with the normal level of <100 mg/dl,) or in
`non-fasting state (elevated glucose level of >180 mg/dl).
`
`[0019] By adrenergic postprandial syndrome (reactive
`hypoglycaemia) the clinician means a functional disorder in
`which a disproportionately high insulin level leads to a drop
`in the blood sugar level (hypoglycaemia) caused by an
`imbalance between rapidly digested carbohydrates and a
`high insulin level persisting after a meal.
`
`[0020] The term diabetic foot refers to lesions on the foot
`caused by diabetes mellitus, the primary cause of which is
`a polyneuropathy that can be put down to inadequate meta-
`
`bolic control. A diabetic foot is diagnosed by the occurrence
`of typical lesions (e.g. ulcers) in an existing case of diabetes
`mellitus.
`
`[0021] The term diabetes-associated ulcer refers to an
`ulcerous inflammatory skin defect in a patient with diabetes
`mellitus. A diabetes-associated ulcer is diagnosed by typical
`anamnesis and physical examination (e.g. inspection of the
`foot).
`
`[0022] The term diabetic hyperlipidaemia is used if a
`patient with diabetes mellitus suffers an increase in total
`cholesterol or, more typically in diabetic hyperlipidaemia,
`an increase in the plasma triglycerides, with or without a
`reduction in HDL cholesterol.
`
`[0023] The term diabetic dyslipidaemia is used if the total
`cholesterol is not raised but the distribution of HDL- and
`LDL-cholesterol is altered, i.e. the patient's HDL cholesterol
`level is too low (e.g. <55 mg/dl for women and <45 mg/dl
`for men).
`
`[0024] The term heart failure is used if either subjective
`symptoms or objective findings indicate an inability of the
`heart to achieve the necessary ejection output. Subjective
`symptoms may be e.g. difficulty breathing under stress or at
`rest. Objective findings include a reduced ejection output of
`the heart according to ultrasound (reduced ejection volume),
`congestion of the lungs according to X-ray, and/or reduced
`walking distances.
`
`DETAILED DESCRIPTION OF THE
`INVENTION
`
`[0025] Some selected DPP IV inhibitors are particularly
`suitable for the preparation of a medicament for the thera-
`peutic treatment of patients who have been diagnosed with
`a medical or physiological functional disorder selected from
`among pre-diabetes, glucose intolerance (impaired glucose
`tolerance), pathological fasting glucose (impaired fasting
`glucose), diabetic foot, diabetes-associated ulcer, diabetic
`hyperlipidaemia, diabetic dyslipidaemia, newly diagnosed
`type 1 diabetes (to maintain a residual secretion of insulin
`from the pancreas), gestational diabetes (diabetes of preg-
`nancy), hyperglycaemia, adrenergic postprandial syndrome
`(reactive hypoglycaemia) or heart failure.
`
`[0026] These medicaments may also be used to reduce the
`risk that in spite of treatment the patient will suffer an
`impaired glucose metabolism, an elevated HbAl c value, an
`impaired fasting glucose value, manifest type 2 diabetes, a
`diabetic foot, a diabetes-associated ulcer, diabetic hyperlipi-
`daemia or diabetic dyslipidaemia, and that in spite of the
`therapy insulin treatment will become necessary or mac-
`rovascular complications will occur.
`
`[0027] Examples of macrovascular complications of this
`kind are myocardial infarct, acute coronary syndrome,
`unstable angina pectoris, stable angina pectoris, haemor-
`rhagic or ischaemic stroke, peripheral arterial occlusive
`disease, cardiomyopathy, left heart insufficiency, right heart
`insufficiency, global heart insufficiency, heart rhythm disor-
`ders and vascular restenosis. These macrovascular compli-
`cations are known to the skilled man and described in detail
`in the standard textbooks.
`
`[0028]
`In addition the substances are suitable for enhanc-
`ing the vitality and secretion capacity of cells after the

`
`transplanting of islets of Langerhans or beta cells, and
`thereby ensuring a favourable outcome after transplantation.
`The substances may also be used during the isolation and
`transplantation phase of islets of Langerhans or beta cells, by
`adding the specified substances to the conventional isolation
`or storage medium in a suitable concentration of 1 nmo1/1 to
`1 µmai, preferably in a concentration of 1 nmo1/1 to 100
`nmo1/1. This results in an improvement in the quality of the
`material to be transplanted. An improvement in quality is
`obtained particularly in combination with added amounts of
`GLP-1 (glucagon like peptide 1), preferably in a concentra-
`tion of 1-100 nmo1/1. Corresponding isolation or storage
`media and corresponding methods of enhancing the vitality
`and secretion capacity of islets of Langerhans or beta cells
`by the addition of DPP IV inhibitors to the media used are
`a further object of the invention.
`
`[0029] Finally, the above-mentioned inhibitors are suit-
`able for the treatment of various forms of arthritis, but
`particularly rheumatoid arthritis.

`
`[0044] These DPP IV inhibitors are distinguished from
`structurally comparable DPP IV inhibitors, as they combine
`exceptional potency and a long-lasting effect with favour-
`able pharmacological properties, receptor selectivity and a
`favourable side-effect profile or bring about unexpected
`therapeutic advantages or improvements when combined
`with other pharmaceutical active substances. Their prepara-
`tion is disclosed in the publications mentioned.
`
`[0045] As different metabolic functional disorders often
`occur simultaneously, it is quite often indicated to combine
`a number of different active principles with one another.
`Thus, depending on the functional disorders diagnosed,
`improved treatment outcomes may be obtained if a DPP IV
`inhibitor is combined with an active substance selected from
`among the other antidiabetic substances, especially active
`substances that lower the blood sugar level or the lipid level
`in the blood, raise the HDL level in the blood, lower blood
`pressure or are indicated in the treatment of atherosclerosis
`or obesity.
`
`[0046] The dosage required of the DPP IV inhibitors when
`administered intravenously is 0.1 mg to 10 mg, preferably
`0.25 mg to 5 mg, and when administered orally 0.5 mg to
`100 mg, preferably 2.5 mg to 50 mg, in each case 1 to 4

`
`times a day. For this purpose the compounds, optionally in
`combination with another active substance, may be formu-
`lated together with one or more inert conventional carriers
`and/or diluents, e.g. with maize starch, lactose, glucose,
`microcrystalline cellulose, magnesium stearate, polyvi-
`nylpyrrolidone, citric acid, tartaric acid, water, water/etha-
`nol, water/glycerol, water/sorbitol, water/polyethylenegly-
`col, (cid:9)
`propyleneglycol, (cid:9)
`cetylstearylalcohol,
`carboxymethylcellulose or fatty substances such as hard fat
`or suitable mixtures thereof, to form conventional galenic
`preparations such as tablets, coated tablets, capsules, pow-
`ders, suspensions or suppositories.
`
`[0047] The DPP IV inhibitors according to the invention
`are thus prepared by the skilled man using permitted for-
`mulation excipients as described in the prior art. Examples
`of such excipients are diluents, binders, carriers, fillers,
`lubricants, flow agents, crystallisation retardants, disinte-
`grants, solubilisers, colourings, pH regulators, surfactants
`and emulsifiers.
`
`[0048] Examples of suitable diluents include cellulose
`powder, calcium hydrogen phosphate, erythritol, (low-sub-
`stituted) hydroxypropylcellulose, mannitol, pregelatinised
`starch or xylitol.
`
`[0049] Examples of suitable binders include copolymers
`of vinylpyrrolidone with other vinyl derivatives (copovi-
`done), hydroxypropylmethylcellulose (HPMC), hydrox-
`ypropylcellulose (HPC) polyvinylpyrrolidone (povidone),
`pregelatinised starch, or low-substituted hydroxypropylcel-
`lulose.
`
`[0050] Examples of suitable lubricants include talc, poly-
`ethyleneglycol, calcium behenate, calcium stearate, hydro-
`genated castor oil or magnesium stearate.
`
`[0051] Examples of suitable disintegrants include maize
`starch or crospovidone. Suitable methods of preparing phar-
`maceutical formulations of the DPP IV inhibitors according
`to the invention are
`
`[0052] Direct tabletting of the active substance in pow-
`der mixtures with suitable tabletting excipients;
`
`[0053] Granulation with suitable excipients and subse-
`quent mixing with suitable excipients and subsequent
`tabletting as well as film coating; or
`
`[0054] packing of powder mixtures or granules into
`capsules.
`
`[0055] Suitable granulation methods are
`
`[0056] wet granulation in the intensive mixer followed
`by fluidised bed drying;
`
`[0057] one-pot granulation;
`
`[0058]
`
`fluidised bed granulation; or
`
`[0059] dry granulation (e.g. by roller compaction) with
`suitable excipients and subsequent tabletting or pack-
`ing into capsules.
`
`[0060] The DPP IV inhibitors mentioned above may also
`be used in conjunction with other active substances, by
`means of which improved treatment results can be obtained.
`Such a combined treatment may be given as a free combi-
`nation of the substances or in the form of a fixed combina-
`tion, for example in a tablet or capsule. Pharmaceutical
`
`formulations of the combination partner needed for this may
