Diabetes Mellitus, Type 2
Conditions
Brief summary
The primary objective of the current study is to investigate the safety and tolerability of BI 44847 in male and female patients with type 2 diabetes following oral administration of repeated doses of 100 mg b.i.d, 400 mg b.i.d. and 800 mg b.i.d. over 28 days. A secondary objective is the exploration of the pharmacokinetics and pharmacodynamics of BI 44847 after multiple dosing, including assessment of steady state.

Eligibility
Inclusion criteria
* Male and postmenopausal or hysterectomised female patients with proven diagnosis of type 2 diabetes mellitus treated with diet and exercise only or with one or 2 oral hypoglycaemic agent other than glitazones. In case of 2 oral hypoglycaemic agents, at least one of these may be taken at no more than 50% of its maximum dose; * Age = \> 21 and Age = \<70 years (female hysterectomised and male patients); * Age = \>55 and Age = \<70 years (female postmenopausal patients); * BMI = \>18.5 and BMI = \<40 kg/m2 (Body Mass Index); * Signed and dated written informed consent prior to admission to the study in accordance with GCP and the local legislation.
Exclusion criteria
* Treatment with insulin, glitazones, or more than one oral hypoglycaemic agent (except if 2 agents and at least one of them not taken at more than 50% of maximum dose); * Fasted blood glucose \> 240 mg/dl on two consecutive days during wash-out; HbA1c \> 8.5 % at screening; * Clinically relevant concomitant diseases other than type 2 diabetes, hyperlipidaemia and medically treated hypertension; * History of relevant allergy/hypersensitivity; * Marked baseline prolongation of QT/QTc interval; * History of additional risk factors for TdP; * Any laboratory value outside the reference range and the clinical relevance is not acceptable in the opinion of the investigator, or the value is more than 3 times higher than the upper limit of the reference range; * Concomitant medication except for acetylsalicylic acid, statins, antihypertensives (diuretics not allowed), beta-blockers for BPH and occasional use of paracetamol (doses of no more than 1000 mg; no more than 2000 mg per day; no more than 2 days per week); * Change of drug dosing of allowed co-medication \< the last 6 weeks; Intake of any medication \< 5 half-lives of the respective drug prior to first administration of study medication or during the trial, except allowed co-medication; * Use of drugs which might reasonably influence the results of the trial or that prolong the QT/QTc interval (based on the knowledge at the time of patient inclusion) \< 10 days prior to first administration of study medication or during the trial; * Use of grapefruit (or its juice) \< 10 days prior to first administration of study medication or during the trial; * Participation in another trial with an investigational drug \< two months prior to first administration of study medication or during the trial; Smoker; * Inability to refrain from smoking on specified trial days; Alcohol abuse; * Drug abuse; * Blood donation; * Excessive physical activity; * Male patients not using adequate contraception; * Women of childbearing potential, positive pregnancy test or lactating
