Trial overview
Official title: A randomized, double-blind, placebo controlled, multi-center study to evaluate the pharmacokinetics, safety and efficacy of albiglutide for the treatment of type 2 diabetes mellitus in pediatric patients
Trial description: The incidence of Type 2 Diabetes Mellitus (T2DM) is increasing day by day but the treatment options are limited in children and adolescents. Albiglutide, approved for the treatment of T2DM in adult population, is a novel analogue of glucagon-like peptide-1 (GLP-1) with a sufficiently long half-life to permit once a week injection. The study will be conducted in 2 parts: Part A is a single dose pharmacokinetic (PK) study to confirm the dose and safety of albiglutide in pediatric subjects aged 10 to less than 18 years and Part B is a randomized double-blind placebo controlled study to evaluate the safety and efficacy (glycemic control) of albiglutide in the pediatric population. Treatment duration in Part B is 52 weeks (24 weeks double-blind placebo-controlled and 28 weeks open-label during which all subjects will receive albiglutide). Approximately 210 eligible male and female subjects will be included in the study.

- Diagnosis of T2DM with HbA1c more than or equal to 7.0% [53 millimole per mole (mmol/mol)] and less than 10.0% (85.8 mmol/mol) assessed at screening. Currently treated with regimen of diet and exercise with or without metformin. Subjects on metformin monotherapy should have been treated for a minimum of 8 weeks prior to randomization on a dose above 1000 milligram per day (mg/day) or prior documented maximum tolerated dose (MTD) less than or equal to 1000 mg/day.
- Subjects with Type 1 diabetes mellitus or secondary diabetes mellitus (i.e. any type other than T2DM)
- Female subject is pregnant (confirmed by laboratory testing), planning a pregnancy or lactating.
Inclusion and exclusion criteria
Inclusion criteria:
- Between 10 to less than 18 years of age inclusive at the time of screening.
- Diagnosis of T2DM with HbA1c more than or equal to 7.0% [53 millimole per mole (mmol/mol)] and less than 10.0% (85.8 mmol/mol) assessed at screening. Currently treated with regimen of diet and exercise with or without metformin. Subjects on metformin monotherapy should have been treated for a minimum of 8 weeks prior to randomization on a dose above 1000 milligram per day (mg/day) or prior documented maximum tolerated dose (MTD) less than or equal to 1000 mg/day.
