Study summary

This is a multicenter, randomized, parallel, placebo- and active comparator-controlled phase 2 trial to evaluate the efficacy, safety, pharmacokinetics and immunogenicity in subjects with T2DM.

Patients treated with diet and exercise alone, or in combination with stable metformin monotherapy (≥1500 mg/day or maximum tolerated dose ≥1000 mg/ day.), will be enrolled. Approximately 225 participants will be randomized. The study includes four stages: screening period (up to 2 weeks), lead-in period (2 weeks), treatment period (12 weeks) and safety follow-up period (3 weeks after treatment).
