NCT04994288

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 diet and exercise intervention. 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 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 after 24-week, double-blind treatment. The secondary outcome is to evaluate the efficacy and safety of Supaglutide after 24-week, double-blinded plus 28-week, open-label treatment period.

Study Arms (3)

Supaglutide RP3D high dose

EXPERIMENTAL

during the IIb phase 140 subjects were randomly assigned to supaglutide 1mg, 2mg ,3mg and placebo ; when these subjects meets the 12wks HbA1C result, an interim analysis will be made andRP3D high dose is confirmed by IDMC accoding to interim analysis. So during the phase 3 , subjets will be assigned to RP3D hign dose, RP3D low dose and placebo

Biological: Supaglutide injection

supaglutide RD3D Low dose

EXPERIMENTAL

during the IIb phase 140 subjects were randomly assigned to supaglutide 1mg, 2mg ,3mg and placebo ; when these subjects meets the 12wks HbA1C result, an interim analysis will be made and RP3D high dose is confirmed by IDMC accoding to interim analysis. So during the phase 3, subjets will be assigned to RP3D hign dose, RP3D low dose and placebo

Model Details: This clinical trial includes dosage determination (Phase IIb) and efficacy confirmation stage(Phase III ). Subjects were randomly assigned to once-weekly subcutaneously injected Supaglutide 1mg, 2mg, 3mg and placebo according to a 2:2:2:1 ratio. During the IIb period, after Interim analysis and IDMC confirmed the RP3D high and low doses, subjects were randomly assigned to Supaglutide RP3D high dose, RP3D low dose and placebo group according to a 2:2:1 ratio.
