Primary Outcome Measures :
  1. Hemoglobin A1c at Baseline and Week 26 Endpoint With Last Observation Carried Forward (LOCF) Following Rivoglitazone or Pioglitazone Compared to Placebo as Monotherapy Treatment of Type 2 Diabetes Mellitus [ Time Frame: Baseline up to week 26 post-dose ]
    Percentage of hemoglobin A1c (HbA1c) levels are reported.

  2. Change in Hemoglobin A1c From Baseline Through Week 26 Endpoint With Last Observation Carried Forward (LOCF) Following Rivoglitazone or Pioglitazone Compared to Placebo as Monotherapy Treatment of Type 2 Diabetes Mellitus [ Time Frame: Baseline up to 26 weeks post-dose ]
    Percent change in hemoglobin (HbA1c) levels are reported. Greater (negative) percent change indicates improvement.


Secondary Outcome Measures :
  1. Fasting Plasma Glucose From Baseline Through Week 26 Endpoint With Last Observation Carried Forward (LOCF) Following Rivoglitazone or Pioglitazone Compared to Placebo as Monotherapy Treatment of Type 2 Diabetes Mellitus [ Time Frame: Baseline up to week 26 post-dose ]
    Normal fasting plasma glucose (FPG) levels are being reported. Normal FPG levels range from 70-110 mg/dL. Lower FPG values indicates better clinical outcome, ie. improvement in FPG.

  2. Change in Fasting Plasma Glucose From Baseline Through Week 26 Endpoint With Last Observation Carried Forward (LOCF) Following Rivoglitazone or Pioglitazone Compared to Placebo as Monotherapy Treatment of Type 2 Diabetes Mellitus [ Time Frame: Baseline up to 26 weeks post-dose ]
    The change in normal fasting plasma glucose (FPG) levels are being reported. A greater (negative) change from baseline indicates an improvement in FPG.

  3. Homeostasis Model Assessment Index for Insulin Resistance At Baseline To Week 26 Endpoint With Last Observation Carried Forward (LOCF) Following Rivoglitazone or Pioglitazone Compared to Placebo as Monotherapy Treatment of Type 2 Diabetes Mellitus [ Time Frame: Baseline up to week 26 post-dose ]

    Homeostasis Model Assessment index for Insulin Resistance (HOMA-IR) was calculated as:

    (fasting insulin concentration [μU/mL] x fasting glucose concentration [mmol/L])/22.5 Low HOMA-IR scores indicate high insulin sensitivity, whereas high HOMA-IR scores indicate low insulin sensitivity (insulin resistance). A normal HOMA-IR score is <2.60, HOMA-IR scores 2.60-3.80 are considered "borderline high", and HOMA-IR scores >3.80 are considered "high" and have correlations of insulin resistance. High HOMA-IR scores indicate worse outcome.


  4. Change in Homeostasis Model Assessment Index for Insulin Resistance At Baseline To Week 26 Endpoint With Last Observation Carried Forward Following Rivoglitazone or Pioglitazone Compared to Placebo as Monotherapy Treatment of Type 2 Diabetes Mellitus [ Time Frame: Baseline up to 26 weeks post-dose ]

    The change in the Homeostasis Model Assessment index for Insulin Resistance (HOMA-IR) was calculated as:

    (fasting insulin concentration [μU/mL] x fasting glucose concentration [mmol/L])/22.5 Low HOMA-IR scores indicate high insulin sensitivity, whereas high HOMA-IR scores indicate low insulin sensitivity (insulin resistance). A normal HOMA-IR score is <2.60, HOMA-IR scores 2.60-3.80 are considered "borderline high", and HOMA-IR scores >3.80 are considered "high" and have correlations of insulin resistance. A negative HOMA-IR score indicates an improvement in insulin sensitivity.
