Primary Outcome Measures:
  • 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


Secondary Outcome Measures:
  • 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


Estimated Enrollment: 475
Study Start Date: February 2013
Estimated Study Completion Date: April 2015
Estimated Primary Completion Date: April 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Albiglutide 30 mg weekly
Subjects will be randomly assigned to double blind albiglutide 30 mg weekly treatment for 52 weeks
Drug: Albiglutide 30 mg weekly
Albiglutide will be available as a pen injector that delivers 30mg of albiglutide
Drug: Placebo
