  • Model-adjusted Change From Baseline (BL) in Glycosylated Hemoglobin (HbA1c) at Week 24 [ Time Frame: BL and Week 24 ] [ Designated as safety issue: No ]
    HbA1c is a form of hemoglobin that is measured primarily to identify the average plasma glucose concentration over a 2- to 3 month period. The BL HbA1c value is defined as the last nonmissing value before the start of treatment. Change from BL was calculated as the value at Week 24 minus the value at BL. Based on analysis of covariance (ANCOVA): Change at Week 24=treatment (placebo, albiglutide 30 mg, albiglutide 50 mg)+BL HbA1c+prior diabetes therapy+age category (<65 years versus >=65 years). Par. who discontinued from study treatment before Week 24 had their last on treatment, post-BL HbA1c observation carried forward for the analysis. The open-label liraglutide group was a reference group and not included in the primary endpoint analysis model. Descriptive summary statistics are provided as a separate outcome measure.
  • Mean HbA1c at BL, Week 24, and Change From BL at Week 24 [ Time Frame: BL and Week 24 ] [ Designated as safety issue: No ]
    HbA1c is a form of hemoglobin that is measured primarily to identify the average plasma glucose concentration over a 2- to 3 month period. The BL HbA1c value is defined as the last nonmissing value before the start of treatment. Change from BL was calculated as the value at Week 24 minus the value at BL. Par. who discontinued from study treatment before Week 24 had their last on-treatment, post-BL HbA1c observation carried forward for the summary. The open-label liraglutide group was a reference group; descriptive statistics comparing albiglutide and liraglutide were exploratory endpoints.
Change from Baseline at Week 24 of glycosylated hemoglobin (HbA1c). [ Time Frame: Baseline and Week 24 ] [ Designated as safety issue: No ]
The HbA1c will be assessed to compare two different doses of albiglutide with placebo. Change from baseline will be calculated as: HbA1c value at Week 24 minus HbA1c value at Baseline

  • Change from baseline in HbA1c over time [ Time Frame: Baseline to end of treatment (Week 52) ] [ Designated as safety issue: No ]
    HbA1c will be assessed through Week 52 to compare albiglutide and placebo.
  • The proportion of subjects at HbA1c goals of <6.5% and <7.0% over time [ Time Frame: Baseline to end of treatment (Week 52) ] [ Designated as safety issue: No ]
    The proportion of subjects at HbA1c <6.5% and ,7.0% through Week 52 to compare albiglutide and placebo.
  • Change from Baseline in Fasting Plasma Glucose (FPG) [ Time Frame: Baseline to end of treatment (Week 52) ] [ Designated as safety issue: No ]
    FPG will be assessed through Week 52 comparing albiglutide versus placebo
  • Change from baseline in body weight over time [ Time Frame: Baseline to end of treatment (Week 52) ] [ Designated as safety issue: No ]
    Body weight will be assessed through Week 52 to compare albiglutide and placebo.
  • Time to withdrawal from randomly assigned treatment for any reason, and time to withdrawal from randomly assigned treatment due to hyperglycemia over time [ Time Frame: Baseline to end of treatment (Week 52) ] [ Designated as safety issue: No ]
    Time to study treatment withdrawal will be assessed through Week 52 for any reason and for hyperglycemia to compare albiglutide and placebo.
  • Number of participants with adverse events [ Time Frame: Baseline to 52 weeks ] [ Designated as safety issue: No ]
    Comparison of number of participants with adverse events after treatment with albiglutide and placebo

A Monotherapy Study to Evaluate the Efficacy and Safety of 2 Dose Levels of Albiglutide in Japanese Subjects With Type 2 Diabetes Mellitus (T2DM)
A Randomized, Double-Blind, Placebo-Controlled, Parallel Group, Multicenter Monotherapy Study to Determine the Efficacy and Safety of 2 Dose Levels of Albiglutide in Subjects With Type 2 Diabetes Mellitus

This study is designed to examine the efficacy and safety of 2 dose levels of weekly subcutaneously injected albiglutide compared with placebo and an open label reference arm of daily subcutaneous injections of liraglutide, in Japanese subjects with Type 2 diabetes mellitus.
