4 Weeks Treatment of Type II Diabetic Patients With BI 44847

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.
