A Phase 1 Randomized, Double-blinded, Placebo-controlled Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Efficacy of Cotadutide in Overweight/Obese Subjects with Chinese ancestry with Type 2 Diabetes Mellitus
This is a randomized, double-blinded, placebo-controlled study designed to evaluate the safety, tolerability, PK and efficacy of ascending doses of cotadutide in overweight or obese subjects with T2DM. This study will enroll subjects aged 18 to 74 years with a body mass index (BMI) ≥ 25 and ≤ 35 kg/m2. Subjects will have a diagnosis of T2DM and inadequate blood glucose control as defined by a HbA1c of 7% to 8.5%, and will be on metformin monotherapy in the three months prior to screening. Total 16 Chinese subjects will be randomized to cotadutide or placebo in a 3:1 ratio (cotadutide [n=12] and placebo [n=4]) at multicentre in China mainland. Those subjects who receive cotadutide once daily SC will be titrated to a maximum of 600 μg once daily SC, beginning at 50 μg once daily SC. The study has about 2 weeks screening period, a run-in period of 10 days and an up to 7-week up-titration treatment period followed by a 3-week treatment extension period at the dose of 600 μg and followed by a 28-day follow-up period.
