E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objective of the current study is to investigate the efficacy, safety and tolerability of BI 10773 (10 mg, 25 mg / once daily) compared to placebo given for 24 weeks as add-on therapy to metformin or metformin plus sulfonylurea in patients with T2DM with insufficient glycaemic control. For the open-label part of the study the objective is to estimate the efficacy and safety of BI 10773 in type 2 diabetic patients with very poor glycaemic control (HbA1c > 10 %) for 24 weeks.
|
|
E.2.2 | Secondary objectives of the trial |
1) Change from baseline in body weight after 24 weeks of treatment
2) Change from baseline in Mean Daily Glucose after 24 weeks of treatment
Other exploratory efficacy endpoints: - Occurrence of treat to target efficacy response, that is an HbA1c of <7.0% after 24 weeks of treatment - Occurrence of relative efficacy response (HbA1c lowering by a least 0.5% after 24 weeks of treatment - Change from baseline in HbA1c by visit over time - Change from baseline in waist circumference after 24 weeks of treatment - Change from baseline in fasting plasma glucose (FPG) after 24 weeks of treatment - Change from baseline in FPG by visit over time - Systolic and diastolic blood pressure: Change from baseline to week 24 - Composite endpoint of the following conditions at week 24: HbA1c lowering by at least 0.5% after 24 weeks of treatment; lowering of systolic blood pressure by at least 3 mm Hg and decrease in body weight by more than 2%.

1. Diagnosis of type 2 diabetes mellitus prior to informed consent 2. Male and female patients on a diet and exercise regimen who are pre-treated with immediate release metformin or immediate release metformin plus sulfonylurea (see below for minimum doses). The treatment regimen has to be unchanged for 12 weeks prior to randomisation. Minimum dose for metformin: - > or = 1500 mg/day or - maximum tolerated dose or - maximum dose according to local label Minimum dose for sulfonylurea: - > or = half of the maximal recommended dose or - maximum tolerated dose or - maximum dose according to local label 3. HbA1c of > or = 7.0% and < or = 10% at Visit 1 (screening) in order to be eligible for randomised treatment HbA1c of > 10% at Visit 1 (screening) in order to be eligible for the open-label treatment arm (25 mg BI 10773) 4. Age > or = 18 5. BMI < or = 45 kg/m2 (Body Mass Index) at Visit 1 (Screening) 6. Signed and dated written informed consent by date of Visit 1 in accordance with GCP and local legislation

Any other antidiabetic drug within 12 weeks prior to randomisation except those mentioned in inclusion criterion 2 3. Acute coronary syndrome (non-STEMI, STEMI and unstable angina pectoris), stroke or TIA within 3 months prior to informed consent 4. Indication of liver disease, defined by serum levels of either ALT (SGPT), AST (SGOT), or alkaline phosphatase above 3 x upper limit of normal (ULN) as determined during screening and/or run-in phase 5. Impaired renal function, defined as GFR<30 ml/min (severe renal impairment) during screening and/or run-in phase 6. Bariatric surgery within the past two years and other gastrointestinal surgeries that induce chronic malabsorption 7. Medical history of cancer (except for basal cell carcinoma) and/or treatment for cancer within the last 5 years 8. Contraindications to metformin and/or sulfonyurea according to the local label for those patients that enter the study with the respective background therapy 9. Blood dyscrasias or any disorders causing hemolysis or unstable Red Blood Cell (e.g.malaria, babesiosis, haemolytic anemia). 10. Treatment with anti-obesity drugs 3 months prior to informed consent or any other treatment at the time of screening (i.e. surgery, aggressive diet regimen, etc.) leading to unstable body weight 11.
