E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the current study is to investigate the efficacy, safety and tolerability of BI 1356 (5 mg once daily) compared to placebo given for 24 weeks as add-on therapy to metformin in patients with type 2 diabetes mellitus with insufficient glycaemic control.
|
|
E.2.2 | Secondary objectives of the trial |
Secondary endpoints are •The occurrence of a treat to target efficacy response, that is an HbA1c under treatment of <7.0% after 24 weeks of treatment •Occurrence of relative efficacy response (HbA1c lowering by at least 0.5% after 24 weeks of treatment) •HbA1c reduction from baseline by visit over time •The change from baseline in fasting plasma glucose (FPG) after 24 weeks of treatment •The change from baseline in fasting plasma glucose (FPG) by visit over time •Meal Tolerance Test (MTT): two-hour postprandial glucose (2hPPG) at baseline, after 24 weeks of treatment and change from baseline to week 24 •The occurrence of treat to target efficacy response, that is an HbA1c under treatment of <6.5% after 24 weeks of treatment

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Postprandial glucose (PPG), meal tolerance test (MTT):
A meal tolerance test (MTT) will be an optional part of this trial. In a sub-group of patients (n = 150), a MTT will be performed on the morning of Visits 3 and 7. At the time of site selection, sites will be asked to make a decision as to whether they wish to contribute patients into this sub-study or not. Where possible, sites who do participate, will perform the MTT in all patients recruited at their site. However, this will not be mandatory, and if some patients are not willing or able to stay at the clinic long enough for the MTT to be performed, they may still participate in the main part of the trial. The results of the MTT will be regarded as pharmacodynamic parameters. The two-hour postprandial glucose (2hPPG) at baseline, after 24 weeks of treatment and change from baseline to week 24 is considered as a secondary endpoint of the study. All other pharmacodynamic parameters obtained as part of the MTT will be regarded as other endpoints of the study.
