Conditions

Type 2 Diabetes Mellitus

Brief summary

Primary Objective: To demonstrate the superiority of once weekly injection of efpeglenatide in comparison to placebo in glycated hemoglobin (HbA1c) change in participants with T2DM (Type 2 Diabetes Mellitus) inadequately controlled with diet and exercise. Secondary Objectives: * To demonstrate the superiority of once-weekly injection of efpeglenatide in comparison to placebo on glycemic control * To demonstrate the superiority of once-weekly injection of efpeglenatide in comparison to placebo on body weight * To evaluate the safety of once-weekly injection of efpeglenatide

Detailed description

Study duration per participant is approximately 65 weeks, including a 3-week screening period, 30 weeks core treatment period, 26 weeks extension treatment period, and 6 weeks safety follow up.

Inclusion criteria

* Participants must be at least 18 years of age at the time of signing the informed consent. * Participants with T2DM, and treated with diet and exercise. * Hemoglobin A1c between 7.0% and 10.0% (inclusive) measured by the central laboratory at Screening.

Exclusion criteria

* Clinically relevant history of gastrointestinal disease associated with prolonged nausea and vomiting, including (but not limited to) gastroparesis, unstable and not controlled gastroesophageal reflux disease within 6 months prior to Screening or history of surgery affecting gastric emptying. * History of pancreatitis (unless pancreatitis was related to gallstone and cholecystectomy has been performed) and pancreatitis during previous treatment with incretin therapies, chronic pancreatitis, and pancreatectomy. * Personal or family history of Medullary Thyroidian Cancer (MTC) or genetic conditions that predisposes to MTC (eg multiple endocrine neoplasia syndromes). * Retinopathy or maculopathy with one of the following treatments, either recent (within 3 months of screening) or planned: intravitreal injections or laser or vitrectomy surgery. * Body weight change of ≥5 kg within the last 3 months prior to Screening. * Systolic blood pressure \>180 mmHg and/or diastolic blood pressure \>100 mmHg at Randomization. * End-stage renal disease as defined by estimated glomerular filtration rate (eGFR , by Modification of Diet in Renal Disease \[MDRD\]) of \<15 mL/min/1.73 m2. * Laboratory findings at the Screening Visit: * Alanine aminotransferase (ALT ) or aspartate aminotransferase (AST ) \>3 times the upper limit of the normal (ULN ) or total bilirubin \>1.5 times the ULN (except in case of documented Gilbert's syndrome). * Amylase and/or lipase: \>3 times the ULN laboratory range. * Calcitonin ≥5.9 pmol/L (20 pg/mL). * Gastric surgery or other gastric procedures intended for weight loss within 2 years prior to Screening, or planned during study period. * History of drug or alcohol abuse within 6 months prior to the time of Screening. * Pregnant (demonstrated by serum pregnancy test at Screening) or breast-feeding women. * Women of childbearing potential not willing to use highly effective method(s) of birth control during the study period and for at least 5 weeks after the last dose of study intervention. The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.
