- Change From Baseline in Glycosylated Hemoglobin A1c (HbA1c) After 14 Weeks Treatment [ Time Frame: 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.
- 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 [ Time Frame: 14 weeks ]The proportion of patients who achieved all the targets in a composite endpoint (HbA1c below 7.0% after 14 weeks of treatment; no occurrence of pre-specified moderate or severe gastrointestinal (GI) side effects of metformin, as assessed by the investigators during 14 weeks of treatment)
- Occurence of Metformin Pre-specified Moderate to Severe GI Side Effects Assessed by Investigators During 14 Weeks of Treatment [ Time Frame: 14 weeks ]Proportion of patients who experienced at least one metformin pre-specified moderate or severe GI side effect during 14 weeks
- Change From Baseline in Fasting Plasma Glucose (FPG) After 14 Weeks of Treatment [ Time Frame: Baseline and 14 weeks ]Means are adjusted by treatment, continuous baseline HbA1c and continuous baseline fasting plasma glucose.
- Metformin Pre-specified GI Symptom Intensity Score Assessed by Investigators During 14 Weeks of Treatment [ Time Frame: 14 weeks ]Patients could experience multiple events, therefore, multiple answers were possible for each patient.
- Metformin Pre-specified GI Symptom Intensity Score Assessed by Patients During 14 Weeks of Treatment [ Time Frame: 14 weeks ]The intensity of the GI side effects was also assessed by the patients using VAS scaled from 0 to 10; higher scores indicate more severe events. Means are adjusted by treatment and continuous baseline HbA1c.
- 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 [ Time Frame: 14 weeks ]The proportion of patients who achieved all the targets in a composite endpoint (HbA1c below 6.5% after 14 weeks of treatment; no occurrence of pre-specified moderate or severe GI side effects of metformin, as assessed by the investigators during 14 weeks of treatment).
- Occurrence of Relative Efficacy Response (HbA1c Lowering by at Least 0.5% After 14 Weeks of Treatment) [ Time Frame: 14 weeks ]The proportion of patients who achieved a relative efficacy response (HbA1c lowering by at least 0.5% after 14 weeks of treatment).
- Occurrence of Relative Efficacy Response (HbA1c Lowering by at Least 0.8% After 14 Weeks of Treatment) [ Time Frame: 14 weeks ]The proportion of patients who achieved a relative efficacy response (HbA1c lowering by at least 0.8% after 14 weeks of treatment).
- 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 ]The proportion of patients who achieved all the targets in a composite endpoint (HbA1c lowered by at least 0.5% after 14 weeks of treatment; no occurrence of pre-specified moderate or severe GI side effects of metformin, as assessed by the investigators during 14 weeks of treatment).
- Change From Baseline in Body Weight by Visit at Week 14 [ Time Frame: Baseline and 14 weeks ]Means are adjusted by treatment, continuous baseline HbA1c and continuous baseline weight
- 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 ]The proportion of patients who achieved all the targets in a composite endpoint (HbA1c lowered by at least 0.8% after 14 weeks of treatment; no occurrence of pre-specified moderate or severe GI side effects of metformin, as assessed by the investigators during 14 weeks of treatment).
- Change From Baseline in HbA1c Over Time [ Time Frame: Baseline, 2 weeks and 8 weeks ]Means are adjusted by treatment and continuous baseline HbA1c
