Primary Outcome Measures:
  • The change from baseline in Glycosylated Hemoglobin A1c (HbA1c) after 14 weeks treatment [ Time Frame: 14 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Occurence of metformin pre-specified moderate to severe GI side effects assessed by investigators during 14 weeks of treatment [ Time Frame: 14 weeks ] [ Designated as safety issue: No ]
  • Occurrence of relative efficacy response (HbA1c lowering by at least 0.8% after 14 weeks of treatment) [ Time Frame: 14 weeks ] [ Designated as safety issue: No ]
  • 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 [ Time Frame: 14 weeks ] [ Designated as safety issue: No ]
  • 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 [ Time Frame: 14 weeks ] [ Designated as safety issue: No ]
  • change from baseline in HbA1c by visit over time [ Time Frame: 14 weeks ] [ Designated as safety issue: No ]
  • change from baseline in body weight by visit over time [ Time Frame: 14 weeks ] [ Designated as safety issue: No ]
  • Composite endpoint of occurence of treat to target efficacy response, that is an HbA1c under treatment of <7.0% after 14 weeks of treatment, and no occurence of moderate or severe gastrointestinal (GI) side effects during 14 weeks of treatment [ Time Frame: 14 weeks ] [ Designated as safety issue: No ]
  • Change from baseline in fasting plasma glucose (FPG) after 14 weeks of treatment [ Time Frame: 14 weeks ] [ Designated as safety issue: No ]
  • Metformin pre-specified GI symptom intensity score assessed by investigators during 14 weeks of treatment [ Time Frame: 14 weeks ] [ Designated as safety issue: No ]
  • Metformin pre-specified GI symptom intensity score assessed by patients during 14 weeks of treatment [ Time Frame: 14 weeks ] [ Designated as safety issue: No ]
  • 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 on occurence of moderate or severe metformin pre-specified GI side effects assessed by investigators [ Time Frame: 14 weeks ] [ Designated as safety issue: No ]
  • Occurrence of relative efficacy response (HbA1c lowering by at least 0.5% after 14 weeks of treatment) [ Time Frame: 14 weeks ] [ Designated as safety issue: No ]
