Primary Outcome Measures:
  • The change from baseline in HbA1c after 24 weeks of treatment (for both in main group and additional parallel group). [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The occurrence of treat to target efficacy response in terms of HbA1c < 7.0 % and < 6.5% after 24 weeks of treatment [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
  • The occurrence of relative efficacy response (HbA1c lowering by at least 0.5% after 24 weeks of treatment) [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
  • The change in fasting plasma glucose (FPG) from baseline after 24 weeks of treatment [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
  • The frequency of patients with use of rescue therapy during 24 week treatment period. [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
