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

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.

time frame: Up to Week 8 post dose
description: An AE is any untoward medical occurrence in a subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. AESI including gastrointestinal events, hypoglycemia, injection site reactions, pancreatitis, medullary thyroid cancer, atrial fibrillation/flutter, and pneumonia etc will also be evaluated.

time frame: Up to 28 days post-dose
description: Blood samples will be collected prior to dosing at Baseline and following single-dose administration of albiglutide at indicated time points.
measure: Time to reach half of the maximum plasma concentration (t1/2) of albiglutide: Part A
time frame: Up to 28 days post-dose
description: Blood samples will be collected prior to dosing at Baseline and following single-dose administration of albiglutide at indicated time points.

time frame: Up to Week 24
description: Subjects reaching HbA1c less than 7% at the end of double-blind phase will be analyzed using logistic regression.
measure: Time to hyperglycemia rescue: Part B
time frame: Up to Week 24
description: Time to hyperglycemia rescue will be measured at specific timeframe. Addition of or adjustment to metformin will be the first option for rescue therapy.
measure: Number of subjects with AEs, serious adverse events (SAEs): Part B
time frame: Up to Week 60
description: An AE is any untoward medical occurrence in a subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. Any untoward event resulting in death, life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, congenital anomaly/birth defect or any other situation according to medical or scientific judgement will be categorized as SAE. AESI including gastrointestinal events, hypoglycemia, injection site reactions, pancreatitis, medullary thyroid cancer, atrial fibrillation/flutter, and pneumonia etc will be evaluated.
measure: Number of hypoglycemic episodes: Part B
time frame: Up to Week 60
description: Hypoglycaemic events as per American Diabetes Association (ADA) criteria: severe hypoglycaemia, documented symptomatic hypoglycaemia, asymptomatic hypoglycaemia, probable symptomatic hypoglycaemia and pseudo hypoglycaemia.

description: Blood samples will be collected at intervals for the determination of anti-albiglutide antibodies.
