Primary Outcome Measures:
  • Change From Baseline in Glycosylated Hemoglobin (HbA1c) at 26 Weeks [ Time Frame: Baseline, 26 Weeks ] [ Designated as safety issue: No ]
    HbA1c is a form of hemoglobin that is measured primarily to identify the average plasma glucose concentration over prolonged periods of time. Least square (LS) means of change from baseline in HbA1c were calculated using a mixed-effects model for repeated measures (MMRM) with the change in HbA1c as the dependent variable and treatment, baseline HbA1c, country, oral antihyperglycemic medication (OAM) , visit, and treatment-by-visit interaction as fixed effects, and participant was the random effect.


Secondary Outcome Measures:
  • Change From Baseline in Glycosylated Hemoglobin (HbA1c) at 52 Weeks [ Time Frame: Baseline, 52 Weeks ] [ Designated as safety issue: No ]
    HbA1c is a form of hemoglobin that is measured primarily to identify the average plasma glucose concentration over prolonged periods of time. LS means of change from baseline in HbA1c were calculated using a MMRM with the change in HbA1c as the dependent variable and treatment, baseline HbA1c, country, OAM, visit, and treatment-by-visit interaction as fixed effects, and participant was as the random effect.

  • Percentage of Participants Attaining HbA1c of <7% or ≤6.5% at 26 Weeks and 52 Weeks [ Time Frame: Up to 26 and 52 weeks ] [ Designated as safety issue: No ]
    The percentage of participants was calculated by dividing the number of participants reaching target HbA1c by the total number of participants analyzed, multiplied by 100.

  • Change From Baseline in Fasting Blood Glucose (FBG) at 26 Weeks and 52 Weeks [ Time Frame: Baseline, 26 Weeks, 52 Weeks ] [ Designated as safety issue: No ]
    LS means of change from baseline were calculated using MMRM with the change in FBG as the dependent variable and treatment, baseline value, country, OAM, visit, and treatment-by-visit interaction as fixed effects, and participant was the random effect.

  • Change From Baseline in Homeostasis Model Assessment 2 Steady-state Beta (β)- Cell Function (HOMA2-%B) at 26 Weeks and 52 Weeks [ Time Frame: Baseline, 26 weeks, 52 weeks ] [ Designated as safety issue: No ]
    The updated Homeostasis Model Assessment (HOMA2) was used to quantify steady state beta-cell function (%B). HOMA2-%B is a computer model that uses fasting plasma insulin and glucose concentrations to estimate %B as a percentage of a normal reference population. LS means were calculated using an analysis of covariance (ANCOVA) model with change from baseline in HOMA-%B as a covariate and country, baseline measurement, OAM, and treatment as fixed effects.

  • Rate of Hypoglycemic Episodes [ Time Frame: Baseline through 26 weeks or 52 weeks ] [ Designated as safety issue: Yes ]
    Hypoglycemic events (HE) were classified as documented symptomatic hypoglycemia, asymptomatic hypoglycemia, severe hypoglycemia, and probable symptomatic hypoglycemia. The 1-year adjusted rate of HEs is summarized cumulatively at 26 weeks and 52 weeks. A summary of serious and other non-serious adverse events regardless of causality is located in the Reported Adverse Events module.

  • Change From Baseline in 7-point Self-monitored Blood Glucose (SMBG) Profiles at 26 Weeks and 52 Weeks [ Time Frame: Baseline, 26 Weeks, 52 Weeks ] [ Designated as safety issue: No ]
    Participants were required to perform 7-point SMBG profiles on 2 separate, nonconsecutive days during the 2 weeks before randomization and Weeks 8, 14, 20, 26, 39, and 52 (or the Early Discontinuation Visit). SMBG measurements were taken using a plasma-equivalent blood glucose (BG) meter at 7 time points: morning pre-meal, morning 2 hours post-meal, mid-day pre-meal, mid-day 2 hours post-meal, evening pre-meal, evening 2 hours post-meal, and at bedtime. Mean and Week 26 and Week 52 was assessed in all treatment groups. LS means of change from baseline were calculated using MMRM with the change in 7-point SMBG as the dependent variable and treatment, baseline value, country, OAM, visit, and treatment-by-visit interaction as fixed effects, and participant was the random effect.

  • Change From Baseline in Homeostasis Model Assessment 2 Insulin Sensitivity - Cell Function (HOMA2-%S) at 26 Weeks and 52 Weeks [ Time Frame: Baseline, 26 Weeks, 52 Weeks ] [ Designated as safety issue: No ]
    The HOMA2 was used to estimate the steady-state insulin sensitivity (%S). HOMA2-S is a computer model that uses fasting plasma insulin and glucose concentrations to estimate insulin sensitivity (%S) as a percentage of the normal reference population. LS means were calculated using an ANCOVA model with change from baseline in HOMA-%S as a covariate and country, baseline measurement, OAM, and treatment as fixed effects.
