Brief Summary:
The objective of the study is to test the efficacy, safety and tolerability of several doses of BI 1356 BS (1, 5, or 10 mg taken once daily) compared to placebo given for 12 weeks together with metformin in patients with type 2 diabetes mellitus who are not at goal with their HbA1c levels. In addition, there will be an unblinded treatment arm with glimepiride as add-on therapy to metformin for comparison. The influence of several factors (gender, age, weight, race, etc.) on the bioavailability and efficacy of BI 1356 BS will also be tested in this study.

Primary Outcome Measures :
  1. HbA1c Change From Baseline at Week 12 [ Time Frame: Baseline and week 12 ]
    HbA1c is measured as a percentage. Thus, this change from baseline reflects the Week 12 HbA1c percent minus the HbA1c percent baseline value. Means are treatment adjusted for baseline HbA1c.


Secondary Outcome Measures :
  1. Percentage of Patients With HbA1c<=7.0% at Week 12 [ Time Frame: week 12 ]
    Descriptive calculation of Patients with HbA1c <= 7.0% at Week 12.

  2. Fasting Blood Plasma Glucose Level (FPG) Change From Baseline at Week 12 [ Time Frame: Baseline and week 12 ]
    This change from baseline reflects the Week 12 FPG minus the baseline FPG. Means are treatment adjusted for baseline HbA1c, baseline FPG and previous anti-diabetic medication.
