Exclusion Criteria

Primary Outcome Measures

Name	Time	Method
Main Objective: The objective of the study is to investigate the efficacy, safety and tolerability of empagliflozin 10 mg qd and empagliflozin 25 mg qd compared to placebo given for 24 weeks in inadequately controlled T2DM (type 2 diabetes mellitus) patients on linagliptin 5 mg and maximum tolerated dose of metformin. The primary objective of efficacy evaluation is planned after 24 weeks of treatment. The study is designed to show superiority of the combination of empagliflozin and linagliptin FDC (fixed dose combination) over linagliptin alone.;Secondary Objective: Not applicable;Primary end point(s): The primary endpoint in this study is the change of HbA1c (HbA1c after 24 weeks of double-blind treatment at week 42 (Visit 9) from baseline (Visit 5)). HbA1c will be measured in the unit of % and mmol/mol.;Timepoint(s) of evaluation of this end point: After 24 week double-blind treatment, from baseline at visit 5 to visit 9
