NCT04998032

Brief Summary

This is a study to evaluate the efficacy and safety of Supaglutide injection in the treatment of type 2 diabetes patients with poor glycemic control after metformin treatment. This trial includes dosage determination (Phase IIb) and efficacy confirmation stage(Phase III ). The primary outcome of the phase IIb period is to preliminarily evaluate the efficacy and safety of Supaglutide combined with metformin and to provide the recommended dosage for the Phase 3 period after 12-week treatment. The primary outcome of the Phase III period is to evaluate the efficacy and safety of Supaglutide combined with metformin treatment after 24-week, double-blind treatment. The secondary outcome is to evaluate the efficacy and safety of Supaglutide combined with metformin during the 24-week, double-blinded plus 28-week, open-label treatment period.

Model Details: This clinical trial includes dosage determination (Phase IIb) and efficacy confirmation stage(Phase III ). During the phase IIb, subjects were randomly assigned to Supaglutide 1mg + metformin, Supaglutide 3mg + metformin and placebo + metformin according to a 1:1:1 ratio. When 120 subjects complete the 12 weeks of follow-up, Interim analysis will be performed and the results be evaluated by IDMC to confirm the RP3D dose. And then during the phase III, subjects were randomly assigned to Supaglutide RP3D + metformin, placebo + metformin group according to a 1:1 ratio.
