-6.5-8.0% at screening for patients treated with two oral antidiabetic agents ( wash-out required)
4.HbA1c of 7.5%-10.0% at visit 3 ( beginning of the 2-week placebo run-in period)

Primary Outcome Measures

Name	Time	Method
Main Objective: Investigate the efficacy, safety and tolerability of several doses of BI 1356 BS ( 0.5 mg, 2.5 mg and 5.0 mg daily) compared to placebo over 12 weeks of treatment in patients with Type 2 diabetes and insufficient glycemic control. An open label treatment arm with, metformin will be used for sensitivity analysis. Population pharmacokinetics of BI 1356 BS will also be assessed.;Secondary Objective: ;Primary end point(s): Change of HbA1c ( HbA1c at 12 weeks of treatment minus HbA1c at baseline). Throughout the study protocol the term baseline” refers to the last observation prior to any study treatment.
