Primary Outcome Measures

Name	Time	Method
Main Objective: The objective of the current study is to investigate the efficacy, safety and pharmacokinetics of three doses of BI 10773 compared to placebo given for 12 weeks in patients with T2DM with insufficient glycemic control. <br><br>In addition, there will be an open-label treatment arm with metformin for sensitivity measurement within this patient population. Pharmacokinetics of BI 10773 will also be assessed in this study.<br>;Secondary Objective: ;Primary end point(s): The primary endpoint in this study is the change of HbA1c from baseline after 12 weeks of treatment.
