Brief Summary:
This Phase IIIb, randomized, double-blind, parallel-group, placebo-controlled, multicenter, treat-to-target study of 26 weeks treatment duration will evaluate the efficacy and safety of once-weekly albiglutide versus placebo as add-on to intensified basal-bolus insulin therapy (with or without metformin) in subjects with Type 2 Diabetes Mellitus (T2DM). Approximately 450 subjects will be randomly assigned in a 1:1 ratio to 1 of 2 treatment groups: albiglutide + intensified basal-bolus insulin therapy (with or without metformin) or placebo + intensified basal-bolus insulin therapy (with or without metformin. The total duration of a subject's participation will be approximately 32 weeks.

Arm Intervention/treatment
Experimental: Albiglutide
Subjects will receive once-weekly subcutaneous injections of albiglutide 30 mg (with forced uptitration to albiglutide 50 mg at Week 4) in addition to intensification of background basal-bolus insulin therapy (with or without metformin) according to predefined 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

Placebo Comparator: Matching albiglutide placebo
Subjects will receive once-weekly subcutaneous injections of matching albiglutide placebo in addition to intensification of background basal-bolus insulin therapy (with or without metformin) according to predefined titration algorithms
Drug: Matching albiglutide placebo
Matching albiglutide placebo will be provided as 0.5-mL injection, fully disposable pen injector system

  3. HbA1c change from baseline in over time [ Time Frame: Up to Week 26 ]
  4. Fasting plasma glucose (FPG) change from Baseline at Week 26 and over time [ Time Frame: Up to Week 26 ]
  5. Proportion of subjects achieving a HbA1c <7.0% and < 6.5% at Week 26 and over time [ Time Frame: Up to Week 26 ]
  6. Percentage of subjects achieving HbA1c <7.0% without weight gain after 26 weeks of treatment [ Time Frame: Up to Week 26 ]
  7. Percentage of subjects achieving HbA1c <7.0% without severe or documented symptomatic hypoglycemia after 26 weeks of treatment [ Time Frame: Up to Week 26 ]
  8. Percentage of subjects achieving HbA1c <7.0% without weight gain and without severe or documented hypoglycemia after 26 weeks of treatment [ Time Frame: Up to Week 26 ]
  9. Number of subjects with non-serious adverse events (AE), serious adverse events (SAE), and AEs and SAEs leading to discontinuation [ Time Frame: Up to Week 30 ]
  10. Incidence of hypoglycemic events [ Time Frame: Up to Week 30 ]
  11. Assessment of clinical laboratory tests, lipids, vital signs, ECGs and physical examinations [ Time Frame: Up to Week 30 ]

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Male or female, 18 years of age or older (inclusive at the time of Screening) with T2DM
  • HbA1c >=7.5% and <=10.0% at Screening.
  • Currently treated with a basal-bolus insulin regimen (with or without metformin) for at least 3 months before Screening. The subject must be taking the following: Basal insulin (1 or 2 daily injections of neutral protamine Hagedorn insulin, insulin glargine, insulin detemir, or insulin degludec) AND Bolus insulin (at least 2 injections of regular insulin, insulin glulisine, insulin aspart, or insulin lispro); In addition, the total daily dose of insulin must be <=150 units; If taking metformin, a stable dose for at least 8 weeks before Screening. Note: Subject should not have received any other antidiabetic medication within 30 days before Screening (e.g., glucagon-like peptide-1 receptor [GLP-1R] agonist, dipeptidyl peptidase-IV inhibitor, sulfonylurea, or thiazolidinedione). Subjects receiving commercially available premixed basal and prandial insulin are not eligible for this study.
  • Body mass index <=40 kilogram (kg) per squaremeter (m^2)
  • Thyroid-stimulating hormone (TSH) level is normal or clinically euthyroid as demonstrated by further thyroid tests (e.g., free T4 )
  • Female subjects of childbearing potential (i.e., not surgically sterile and/or not postmenopausal) must be practicing adequate contraception (as defined in the protocol) for the duration of participation in the study including the 4-week Posttreatment Follow-up Period.
  • Willing and able to comply with all study procedures including intensive insulin administration and performance of frequent SMBG profiles according to the protocol
  • Able and willing to provide written informed consent

  • Fasting triglyceride level >750 mg/dL at Screening

  • Known allergy to albiglutide or any product components (including yeast and human albumin), any other GLP-1 analogue, insulin, or other study medication's excipients OR other contraindications (per the prescribing information) for the use of potential study medications (e.g., basal-bolus insulin)
  • Use of oral or systemically injected glucocorticoids within the 3 months before randomization or high likelihood of a requirement for prolonged treatment (>1 week) in the 6 months following randomization. However, short courses of oral steroids (single dose or multiple doses for up to 7 days) may be permitted provided these cases are discussed with the medical monitor. Inhaled, intra-articular, epidural, and topical corticosteroids are allowed
  • Female subject is pregnant (confirmed by laboratory testing) or lactating
  • Receipt of any investigational drug within the 30 days or 5 half-lives, whichever is longer, before Screening, a history of receipt of an investigational antidiabetic drug within the 3 months before randomization, or receipt of albiglutide in previous studies
