Primary Outcome Measures:
  • Change From Baseline in Hemoglobin A1C (HbA1c) at Endpoint (Last Observation Carried Forward [LOCF]) [ Time Frame: Baseline, Endpoint (LOCF) up to 24 weeks ] [ Designated as safety issue: No ]
    Least squares mean values were controlled for Baseline + Baseline HbA1c Group + Baseline sulfonylurea (SU) Group.


Secondary Outcome Measures:
  • Actual Hemoglobin A1C at 24 Weeks and Endpoint (LOCF) [ Time Frame: 24 weeks, Endpoint (LOCF) up to 24 weeks ] [ Designated as safety issue: No ]
    Least squares mean values were controlled for Baseline + Baseline HbA1c Group + Baseline SU Group.

  • Change From Baseline in Hemoglobin A1C at 24 Weeks and Endpoint (LOCF) [ Time Frame: Baseline, 24 Weeks, Endpoint (LOCF) up to 24 weeks ] [ Designated as safety issue: No ]
    Least squares mean values were controlled for Baseline + Baseline HbA1c Group + Baseline SU Group.

  • Percentage of Participants With Hemoglobin A1C Less Than 7.0% and Hemoglobin A1C Less Than or Equal to 6.5% [ Time Frame: Weeks 12, 18, 24 and Endpoint (LOCF) up to 24 weeks ] [ Designated as safety issue: No ]
  • 7-Point Self-Monitored Blood Glucose (SMBG) Profiles at Baseline and Endpoint (LOCF) [ Time Frame: Baseline, Endpoint (LOCF) up to 24 weeks ] [ Designated as safety issue: No ]
    SMBG at morning pre-meal, morning post-prandial, midday pre-meal, midday post-prandial, evening pre-meal, evening postprandial, 0300 hours. Post-prandial glucose is measured 2 hours after the start of the meal.

  • Glycemic Variability at Baseline and Endpoint (LOCF) [ Time Frame: Baseline, Endpoint (LOCF) up to 24 weeks ] [ Designated as safety issue: No ]
    Glycemic variability was defined as the standard deviation (SD) of a participant's intra-day 7-point, self-monitored, blood glucose. Mean SD was calculated based on the SD for each participant in the study.

  • Incidence of Self-reported Hypoglycemic Episodes (All, Non-Nocturnal, Nocturnal, and Severe) [ Time Frame: Baseline to Endpoint (LOCF) up to 24 weeks ] [ Designated as safety issue: Yes ]
    Overall:any time after randomization.Episode:any time patient experienced sign/symptom associated with hypoglycemia, or had blood glucose level ≤70 mg/dL. Non-nocturnal:any episode that occurred between waking and bedtime. Nocturnal:any episode that occurred between bedtime and waking.Severe:episode with symptoms consistent with neuroglycopenia in which patient requires assistance,and is associated with:blood glucose value <50 mg/dL or prompt recovery after oral carbohydrate, glucagon, or intravenous glucose.Incidence(%)=(Number of patients experiencing episodes/number of patients in arm)*100.

  • Rate of All, Non-Nocturnal, and Nocturnal Self-Reported Hypoglycemic Episodes (Adjusted for One Year) [ Time Frame: Baseline to Endpoint (LOCF) up to 24 weeks ] [ Designated as safety issue: Yes ]
    Rate of self-reported hypoglycemic episodes, all, non-nocturnal, and nocturnal, at Endpoint (LOCF) and overall. Rate is reported as episodes/participant/365 days. Episode = any time participant feels that he/she is experiencing a sign or symptom that is associated with hypoglycemia or has a blood glucose level of ≤70 mg/dL, even if it was not associated with signs, symptoms, or treatment. Overall=any time during the post-randomization visits within the study period. Nocturnal=Any episode that occurs between bedtime and waking. Non-Nocturnal=Any episode that occurs between waking and bedtime.

  • Actual Body Weight at Baseline and Endpoint (LOCF) [ Time Frame: Baseline, Endpoint (LOCF) up to 24 weeks ] [ Designated as safety issue: Yes ]
  • Change From Baseline in Body Weight at Endpoint (LOCF) [ Time Frame: Baseline, Endpoint (LOCF) up to 24 weeks ] [ Designated as safety issue: Yes ]
  • Total Daily Insulin Dose at Endpoint (LOCF) [ Time Frame: Endpoint (LOCF) up to 24 weeks ] [ Designated as safety issue: No ]
