Arms & Interventions
Albiglutide 30 mg weekly
Subjects will be randomly assigned to double blind albiglutide 30 mg weekly treatment for 52 weeks
Intervention: Albiglutide 30 mg weekly
Albiglutide 30 mg weekly
Subjects will be randomly assigned to double blind albiglutide 30 mg weekly treatment for 52 weeks
Intervention: Placebo
Albiglutide 50 mg weekly
Subjects will be randomly assigned to double blind albiglutide 50 mg weekly until Week 52

Intervention: Placebo
Liraglutide 0.9 mg daily
Subjects will be randomly assigned to open-label liraglutide for 52 weeks
Intervention: Liraglutide 0.9 mg daily
Outcomes
Primary Outcomes
Model-adjusted Change From Baseline in Glycosylated Hemoglobin (HbA1c) at Week 24
Time Frame: Baseline and Week 24
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 Baseline HbA1c value is defined as the last nonmissing value before the start of treatment. Change from Baseline was calculated as the value at Week 24 minus the value at Baseline. Based on analysis of covariance (ANCOVA): Change at Week 24 = treatment (placebo, albiglutide 30 mg, albiglutide 50 mg) + Baseline HbA1c + prior diabetes therapy + age category (\<65 years versus ≥65 years). Participants who discontinued from study treatment before Week 24 had their last post-Baseline HbA1c carried forward for the analysis unless the value is past 14 days after the last dose of study drug. 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 Baseline, Week 24, and Change From Baseline at Week 24
Time Frame: Baseline and Week 24
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 Baseline HbA1c value is defined as the last nonmissing value before the start of treatment. Change from Baseline was calculated as the value at Week 24 minus the value at Baseline. Participants who discontinued from study treatment before Week 24 had their last post-Baseline HbA1c value carried forward for the summary, unless the value was past 14 days after the last dose of study drug. The open-label liraglutide group was a reference group; descriptive statistics comparing albiglutide and liraglutide were exploratory endpoints.
