Primary Outcome Measures:
  • Change From Baseline in Hemoglobin A1c (HbA1c ) at Week 12 [ Time Frame: 12 Weeks ] [ Designated as safety issue: No ]
    Change from the baseline measurement, where the baseline measurement was obtained at randomization (0 week) before receiving study medication.


Secondary Outcome Measures:
  • Change From Baseline in Fasting Plasma Glucose at Week 12 [ Time Frame: 12 Weeks ] [ Designated as safety issue: No ]
    Change from baseline measurement, where the baseline measurement was obtained at randomization (0 week) before receiving study medication.


Other Outcome Measures:
  • Change From Baseline in 2 Hour Postprandial Glucose at Week 12 [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    Change from baseline measurement, where the baseline measurement was obtained at randomization (0 week) before receiving study medication.

  • Change From Baseline in Hemoglobin A1c (HbA1c ) at Week 52 [ Time Frame: Week 52 (reflecting change from Week 0) for Sitagliptin/Sitagliptin group; Weeks 52 (reflecting change from Week 12) for Placebo/Sitagliptin group. ] [ Designated as safety issue: No ]
    Change from the last value before receiving sitagliptin therapy: Week 0 for Sitagliptin/Sitagliptin group and Week 12 for the Placebo/Sitagliptin group.
