简要总结

The aim of this study is to investigate the impact of the combination therapy of linagliptin and metformin at submaximal doses in reduction of Glycosylated haemoglobin (HbA1c) and metformin pre-specified gastro-intestinal (GI) side effects in treatment naive patients of with type 2 diabetes mellitus.

结局指标

主要结局

Change From Baseline in Glycosylated Hemoglobin A1c (HbA1c) After 14 Weeks Treatment

时间窗: Baseline and 14 weeks

Adjusted mean change in HbA1c from baseline at Week 14 was analysed using an ANCOVA model. The Model included treatment and continuous baseline HbA1c.

次要结局

  • Occurence of Metformin Pre-specified Moderate to Severe GI Side Effects Assessed by Investigators During 14 Weeks of Treatment(14 weeks)
  • Composite Endpoint of Occurence of Relative Efficacy Response (HbA1c Lowering by at Least 0.5% After 14 Weeks of Treatment) and no Occurence of Moderate and Severe Metformin Pre-specified GI Side Effects Assessed by the Investigators During 14 Weeks(14 weeks)
  • Occurrence of Relative Efficacy Response (HbA1c Lowering by at Least 0.5% After 14 Weeks of Treatment)(14 weeks)
  • Metformin Pre-specified GI Symptom Intensity Score Assessed by Investigators During 14 Weeks of Treatment(14 weeks)
  • Composite Endpoint of Occurrence of Treat to Target Efficacy Response, That is an HbA1c Under Treatment of <6.5% After 14 Weeks of Treatment, and no Occurrence of Moderate or Severe Metformin Pre-specified GI Side Effects Assessed by Investigators(14 weeks)
  • Occurrence of Relative Efficacy Response (HbA1c Lowering by at Least 0.8% After 14 Weeks of Treatment)(14 weeks)
  • Change From Baseline in Body Weight by Visit at Week 14(Baseline and 14 weeks)
  • Change From Baseline in Fasting Plasma Glucose (FPG) After 14 Weeks of Treatment(Baseline and 14 weeks)
  • Change From Baseline in HbA1c Over Time(Baseline, 2 weeks and 8 weeks)
  • Composite Endpoint of Occurrence of Treat to Target Efficacy Response, That is an HbA1c Under Treatment of <7.0% After 14 Weeks of Treatment, on no Occurrence of Moderate or Severe Gastrointestinal (GI) Side Effects During 14 Weeks of Treatment(14 weeks)
  • Metformin Pre-specified GI Symptom Intensity Score Assessed by Patients During 14 Weeks of Treatment(14 weeks)
  • Composite Endpoint of Occurrence of Relative Efficacy Response (HbA1c Lowering by at Least 0.8% After 14 Weeks of Treatment) and no Occurrence of Moderate and Severe Metformin Pre-specified GI Side Effects Assessed by Investigators During 14 Weeks(14 weeks)
