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.
• FPG less than 240 mg/deciliter (dL) at screening.
• Fasting C-peptide more than or equal to 0.8 nanogram per milliliter (ng/mL) at screening.
• Negative central laboratory assays for Glutamic Acid Decarboxylase 65 (GAD-65) and Islet Cell Autoantigen 512 (ICA512) autoantibodies at screening.
• Body weight more than or equal to 30 kilogram (kg) at screening.
• Male subjects will be included. Female subjects who have achieved menarche and are of childbearing potential must be practicing adequate contraception for the duration of participation in the study.
• Signed informed consent of parent or legal guardian and assent as appropriate will be obtained from the child.

Exclusion Criteria:

• 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.
• History of cancer that has not been in full remission for at least 3 years before screening.
• History of thyroid cancer.
• Personal history or family history of thyroid medullary carcinoma or multiple endocrine neoplasia type 2 (MEN2).
• History of pancreatitis or considered clinically at significant risk of developing pancreatitis during the course of the study (e.g. due to symptomatic gallstones).
• Severe gastroparesis within 6 months prior to screening.
• History of significant gastrointestinal (GI) surgery that in the opinion of the investigator is likely to significantly affect upper GI or pancreatic function.
• Have a history of at least one episode of diabetic ketoacidosis (DKA) after receiving anti-diabetic medication.
• Fasting triglyceride level more than 750 mg/dL at screening.
• Serum calcitonin more than 50 picogram (pg/mL) at screening.
• Hemoglobinopathy that may affect determination of HbA1c.
• Uncontrolled hypertension at screening.
• Estimated Glomerular Filtration Rate (eGFR) less than 90 mL/minute/1.73 meter^2 (calculated using the Schwartz equation) at screening.
• ALT more than 2.5x upper limit of normal (ULN) or Bilirubin more than 1.5xULN (isolated bilirubin more than 1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin more than 35%) at screening.
• Current active liver or biliary disease (with the exception of Gilbert's syndrome or asymptomatic gallstones or otherwise stable chronic liver disease per investigator assessment).
• Current or previous insulin therapy used for more than 4 weeks (continuously) in the 3 months prior to screening.
• Use of a GLP-1receptor agonist at study entry and during the study.
• Any oral diabetic medications, except metformin, at study entry and during the study.
• Use of oral or systemically injected glucocorticoids is generally not allowed within the 3 months before 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.
• Weight loss medications.
• Antiretroviral drugs.
• Known allergy or serious hypersensitivity reaction 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.
• Any other reason the investigator deems the subject to be unsuitable for the study or may interfere with trial compliance (e.g. significant medical or psychiatric history).
• The subject has participated in a clinical trial and has received an investigational product or device within the following time period prior to the first dosing day in the current study: 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer).
