Brief Summary:
This Phase IIIb, randomized, open-label, parallel group, active control, multicenter, treat to-target study of 26 weeks' treatment duration will evaluate the efficacy and safety of once-weekly albiglutide as replacement of prandial insulin in subjects with type 2 diabetes mellitus (T2DM) failing to achieve adequate glycemic control on their current basal bolus insulin regimen (with or without metformin). Approximately 794 subjects will be randomly assigned in a 1:1 ratio to 1 of 2 treatment groups: albiglutide + insulin glargine (with insulin lispro discontinuation at Week 4) (with or without metformin) or to intensification of insulin glargine + insulin lispro (with or without metformin). The study will comprise 4 study periods : Screening (2 weeks), Standardization (4 weeks), Treatment (26 weeks), and Post treatment Follow up (4 weeks). The total duration of a subject's participation will be approximately 36 weeks.

Arm Intervention/treatment
Experimental: Albiglutide + Insulin Glargine Arm
During standardization period, subjects will transit from basal bolus regimen received during screening period to insulin glargine plus insulin lispro. During treatment period, subject will receive Albiglutide 30 milligrams (mg) weekly subcutaneous (SC) injection and insulin lispro dose will be downtitrated to half that used in the standardization period. At Week 4, Albiglutide will be uptitrated to 50 mg weekly SC injection and insulin lispro will be stopped for the remainder of the treatment Period. Insulin lispro may be re-introduced after Week 8 according to pre-defined hyperglycemia thresholds. Insulin will be adjusted according to protocol-defined insulin titration algorithms
Drug: Albiglutide
Albiglutide is intended for self-administration as a SC injection. It is provided as a fixed dose of 30 mg of albiglutide or 50 mg of albiglutide in a 0.5 mL injection volume, fully disposable pen injector

Experimental: Insulin Glargine + Insulin Lispro Arm
During standardization period, subjects will transit from basal bolus regimen received during screening period to insulin glargine plus insulin lispro. During treatment period, subject will continue with the same doses as at the end of the standardization period and doses will be adjusted according to protocol-defined insulin titration algorithms
Drug: Insulin Glargine and Insulin Lispro
Insulin glargine and insulin lispro will be provided as injection pens for SC injection




Primary Outcome Measures :
  1. Change From Baseline in Glycosylated Hemoglobin (HbA1c) at Week 26 [ Time Frame: Baseline (Day -1) and Week 26 ]
    HbA1c is glycosylated hemoglobin. It was measured at Baseline and at Week 26. The analysis was conducted using mixed-effect model with repeated measures (MMRM). The model included HbA1c change from Baseline as the dependent variable; treatment, region, age category, current metformin use, visit week, treatment-by-week interaction, and Baseline HbA1c-by-week interaction as fixed effects; Baseline HbA1c as a continuous covariate; and participant as a random effect. The Baseline value was the last available non-missing value prior to the first dose of the randomized treatment, thus Baseline was Day -1. Change from Baseline is defined as the post-Baseline value minus the Baseline value.


Secondary Outcome Measures :
  1. Number of Participants Treated With Once-weekly Albiglutide That Were Able to Discontinue Insulin Lispro at Week 4 and Did Not Meet Prespecified Criteria for Severe, Persistent Hyperglycemia Through Week 26 [ Time Frame: Up to Week 26 ]
    Participants who did not meet prespecified criteria for severe, persistent hyperglycemia through Week 26 were those participants treated with once-weekly albiglutide that were able to replace prandial insulin without lispro re-introduction through Week 26. Number of participants treated with once-weekly albiglutide that were able to discontinue insulin lispro at Week 4 and did not meet prespecified criteria for severe, persistent hyperglycemia through Week 26 have been presented.

  2. Percentage of Participants With Severe or Documented Symptomatic Hypoglycemia Through Week 26 [ Time Frame: Up to Week 26 ]
    Severe hypoglycemia was considered as an event requiring assistance of another person to actively administer carbohydrates, glucagon, or take other corrective actions. Plasma glucose concentrations may not be available during an event, but neurological recovery following the return of plasma glucose to normal was considered sufficient evidence that the event was induced by a low plasma glucose concentration. Documented symptomatic hypoglycemia was an event during which typical symptoms of hypoglycemia are accompanied by a measured plasma glucose concentration <=70 milligrams per deciliters (mg/dL) (<=3.9 millimoles per liters [mmol/L]).

  3. Change From Baseline in Body Weight at Week 26 [ Time Frame: Baseline (Day -1) and Week 26 ]
    Body weight was measured to the nearest 0.1 kilogram on a standard calibrated scale. Participants dressed in light indoor clothes (no coat, jacket, etc.) without shoes and with a voided bladder. The same equipment was used wherever possible. The Baseline value was the last available non-missing value prior to the first dose of the randomized treatment, thus Baseline was Day -1. Change from Baseline is defined as the post-Baseline value minus the Baseline value.

  4. Change From Baseline to Week 26 in Body Weight [ Time Frame: Baseline (Day -1) to Week 26 ]
    Body weight was measured to the nearest 0.1 kilogram on a standard calibrated scale. Participants dressed in light indoor clothes (no coat, jacket, etc.) without shoes and with a voided bladder. The same equipment was used wherever possible. The Baseline value was the last available non-missing value prior to the first dose of the randomized treatment, thus Baseline was Day -1. Change from Baseline is defined as the post-Baseline value minus the Baseline value. Change from Baseline to Week 26 in body weight are presented. FA Population was analyzed. Only those participants available at the specified time points were analyzed represented by n=X,X in the category titles.

  5. Total Daily Insulin Dose at Week 26 [ Time Frame: Week 26 ]
    Insulin dose at Week 26 was defined as the prescribed insulin dose at Week 25. Based on MMRM model, prescribed total daily basal insulin dose was equal to Baseline prescribed total daily basal insulin dose + treatment + Baseline HbA1c category + region + age category + current use of metformin + visit week + treatment-by-visit week interaction + Baseline prescribed total daily basal insulin dose-by-visit week interaction. Total daily insulin dose at Week 26 is presented. Only those participants available at the specified time points were analyzed.

  6. Change From Baseline to Week 26 in HbA1c [ Time Frame: Baseline to Week 26 ]
    HbA1c is glycosylated hemoglobin and was measured up to Week 26. The Baseline value was the last available non-missing value prior to the first dose of the randomized treatment, thus Baseline was Day -1. Change from Baseline is defined as the post-Baseline value minus the Baseline value. Only those participants available at the specified time points were analyzed represented by n=X,X in the category titles.

  7. Change From Baseline in Fasting Plasma Glucose (FPG) at Week 26 [ Time Frame: Baseline and Week 26 ]
    FPG was measured at Baseline (Day -1). FPG values for all participants at Week 26 were not collected due to an error in the protocol and were imputed with the fasting serum glucose (FSG) values at this time point. The imputation of the FPG at Week 26 from the FSG values was deemed acceptable from the results of the analysis of the correlation between FPG and FSG at the screening visit. The Baseline value was the last available non-missing value prior to the first dose of the randomized treatment, thus Baseline was Day -1. Change from Baseline is defined as the post-Baseline value minus the Baseline value.

  8. Change From Baseline to Week 26 in FPG [ Time Frame: Baseline to Week 26 ]
    FPG was measured at Baseline (Day -1) up to Week 26. FPG values for all participants at Week 26 were not collected due to an error in the protocol and were imputed with the FSG values at this time point.

    Lipid parameters included TC, LDL-c, HDL-c, TG and FFA. The Baseline value was the last available non-missing value prior to the first dose of the randomized treatment, thus Baseline was Day -1. Change from Baseline is defined as the post-Baseline value minus the Baseline value. LDL-c and FFA were collected as part of the lipid panel and results were reviewed by investigators for individual participants. Change from Baseline at Week 10 and Week 26 was not assessed for these parameters. Analysis of these parameters was not a specific study objective and would not have any impact on study conclusions. Only those parameters with data values have been presented. Only those participants available at the specified time points were analyzed represented by n=X,X in the category titles.
