A Randomized, Double-blind, Placebo and Active-Controlled, Parallel-group, Multicenter Study to Determine the Efficacy and Safety of Albiglutide Administered in Combination With Metformin and Glimepiride Compared With Metformin Plus Glimepiride and Placebo and With Metformin Plus Glimepiride and Pioglitazone in Subjects With Type 2 Diabetes Mellitus

Change From Baseline (BL) in Glycosylated Hemoglobin (HbA1c) at Week 52

时间窗: Baseline and Week 52

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 non-missing value before the start of treatment. Change from BL was calculated as the value at Week 52 minus the value at BL. Based on analysis of covariance (ANCOVA): change = treatment + BL HbA1c + prior myocardial infarction history + age category + region. The last observation carried forward (LOCF) method was used to impute missing post-BL HbA1c values; the last non-missing post-BL on-treatment measurement was used to impute the missing measurement. HbA1c values obtained after hyperglycemic rescue were treated as missing and were replaced with pre-rescue values. Nine par. with post-BL values obtained \>14 days after the last dose or after hyperglycemic rescue were included in the analysis population but were not analyzed for this endpoint.
