Primary Outcome Measures:
  • Adjusted Mean Change From Baseline in Hemoglobin A1c (HbA1c) at Week 24 Last Observation Carried Forward (LOCF) - All Randomized Participants [ Time Frame: Baseline (Day 1), Week 24 ] [ Designated as safety issue: No ]
    Adjusted mean change in HbA1c from baseline at Week 24, or the last post-baseline measurement prior to Week 24 if no Week 24 assessment was available was determined(LOCF). HbA1c was measured as percent of hemoglobin by a central laboratory. Data after rescue medication (metformin) was excluded from this analysis. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication. In cases where time of the first dose or time of the assessment was not available, baseline was defined as the last assessment on or prior to the date of the first dose of the double-blind study medication. HbA1c values were obtained at enrollment, lead-in, and at Day 1, Weeks 4, 8, 12, 16, 20, and 24 in the double-blind period.


Secondary Outcome Measures:
  • Adjusted Mean Change From Baseline in Total Body Weight at Week 24 (LOCF) - Randomized Participants [ Time Frame: Baseline (Day 1), Week 24 ] [ Designated as safety issue: No ]
    Adjusted mean change in total body weight from baseline at Week 24, or the last post-baseline measurement prior to Week 24 if no Week 24 assessment was available LOCF was determined. Data after rescue medication (metformin) was excluded from this analysis. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication. In cases where time of the first dose or time of the assessment was not available, baseline was defined as the last assessment on or prior to the date of the first dose of the double-blind study medication. Body weight was measured in kilograms (kg) at qualification, lead-in, Day 1, Weeks 1, 2, 4, 8, 12, 16, 20, and 24 during double-blind period.

  • Adjusted Mean Change From Baseline in Fasting Plasma Glucose at Week 24 (LOCF) - Randomized Participants [ Time Frame: Baseline (Day 1), Week 24 ] [ Designated as safety issue: No ]
    Adjusted mean change in fasting plasma glucose (FPG) from baseline at Week 24 (LOCF) was determined. Data after rescue medication (metformin) was excluded from this analysis. FPG was measured as milligrams per deciliter (mg/dL) by a central laboratory at qualification, lead-in, Day 1, Weeks 1, 2, 4, 8, 12, 16, 20, and 24 during double-blind period. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication. In cases where time of the first dose or time of the assessment was not available, baseline was defined as the last assessment on or prior to the date of the first dose of the double-blind study medication.

  • Adjusted Mean Change From Baseline in Effect on 2-hour Post Liquid Meal Glucose at Week 24 (LOCF) - Randomized Participants [ Time Frame: Baseline (Day 1), Week 24 ] [ Designated as safety issue: No ]
    Liquid meal tolerance tests (MTTs) were scheduled to occur at Day 1 visit (MTT was to be completed 2 hours prior to first dose of treatment) and at Week 24 / End of treatment visit, or Rescue visit for participants meeting criteria for rescue due to lack of glycemic control. At Week 24, study treatment was given 1 hour before MTT was administered. Participant fasted for at least 10 hours (h) prior to both visits and abstained from tobacco, alcohol, and caffeine for 24 h prior to the MTT. The liquid meal supplement was administered over 10 minutes, starting immediately after Time 0 blood sample was drawn. Blood samples for post-liquid meal Glucose were obtained at 30, 60, 120, and 180 minutes after ingesting the liquid supplement. Glucose was measured in milligrams per deciliter (mg/dL) by a central laboratory. Baseline was defined as the last assessment prior to the start date and time of the first dose of double-blind study medication.

  • Adjusted Percentage of Participants Achieving a Therapeutic Glycemic Response at Week 24 (LOCF) - Randomized Participants [ Time Frame: Baseline (Day 1), Week 24 ] [ Designated as safety issue: No ]
    Therapeutic glycemic response was defined as HbA1c less than 7.0%. n=Number of participants with HBA1c less than (<) 7 % at Week 24, last observation carried forward (LOCF) while N=number of randomized participants with non-missing baseline and Week 24 (LOCF) values. Percent=n/N and was adjusted for Baseline HbA1c. Data after rescue medication (metformin) was excluded from this analysis. HbA1c was measured as a percent of hemoglobin.

  • Adjusted Mean Change From Baseline in Waist Circumference at Week 24 (LOCF) - Randomization Participants [ Time Frame: Baseline (Day 1), Week 24 ] [ Designated as safety issue: No ]
    Adjusted mean waist circumference values from baseline to Week 24 (or the last post-baseline measurement prior to Week 24 if no Week 24 assessment was available, last observation carried forward, (LOCF) was determined. Data after rescue medication (metformin) was excluded from this analysis. Waist circumference was measured centimeters (cm) and obtained at lead-in, Day 1, and Week 24 of the double-blind period. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication. In cases where time of the first dose or time of the assessment was not available, baseline was defined as the last assessment on or prior to the date of the first dose of the double-blind study medication.

  • Number of Participants With Deaths, Serious AEs (SAEs), Adverse Events (AEs), Discontinuation Due to AEs, During the 12 Week Double Blind Period, Including Data After Rescue - All Treated Participants [ Time Frame: Day 1 of Double Blind Period to end of Week 24 Plus 30 days ] [ Designated as safety issue: Yes ]
    Medical Dictionary for Regulatory Activities (MedDRA), version 12.1 AE=any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that may not have a causal relationship with treatment. SAE=a medical event that at any dose results in death, persistent or significant disability/incapacity, or drug dependency/abuse; is life-threatening, an important medical event, or a congenital anomaly/birth defect; or requires or prolongs hospitalization. Treatment-related=having certain, probable, possible, or missing relationship to study drug as per the investigator. Baseline to last dose plus 4 days for AEs, plus 30 days for SAEs.

  • Number of Participants With Adverse Events of Special Interest During the 12 Week Double Blind Period - All Treated Participants [ Time Frame: Baseline to last dose plus 4 days in 12 Week Double Blind Period ] [ Designated as safety issue: Yes ]
    Participants with AEs of hypoglycemia, cardiac/vascular disorders, renal impairment or failure, volume depletion (hypotension/dehydration/hypovolemia), fractures, urinary stones, and other reports suggestive of genital infection or urinary tract infection (UTI) were summarized using MedDRA version 12.1. Data after rescue included for all AEs of special interest except hypoglycemia; hypoglycemia AEs were prior to rescue. Major hypoglycemic episode: symptomatic requiring 3rd party assistance due to severe impairment in consciousness or behavior with a glucose value < 54 mg/dL and prompt recovery after glucose/glucagon; Minor: either symptomatic with glucose measurement < 63 mg/dL, regardless of need for 3rd party assistance, or asymptomatic with glucose < 63 mg/dL that does not qualify as major; Other: suggestive but not meeting criteria for major or minor.

  • Mean Change From Baseline in Seated Systolic and Diastolic Blood Pressure at Week 24, Including Data After Rescue - Treated Participants [ Time Frame: Baseline (Day 1), Week 24 ] [ Designated as safety issue: Yes ]
    Blood pressure values were obtained on Day 1, Weeks 1, 2, 4, 8, 12, 16, 20, and 24 in the double blind period, after the participant was seated for quietly for 5 minutes; the same arm (right or left) was used consistently through out the study. Measurements were taken at least 10 hours after the last ingestion of caffeine, alcohol, or nicotine. Blood pressure was measured in millimeters of mercury (mmHg). Data after rescue were also included. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication.
