A Study of Efficacy and Safety of Supaglutide in Type 2 Diabetes Patients
Efficacy and Safety of Once-weekly Supaglutide Versus Placebo in Patients With Type 2 Diabetes Suboptimally Controlled on Diet and Exercise: A Multicenter, Randomized, Double-blind, Placebo-controlled Clinical Trial
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.

Detailed Description
This trial includes a 2-week screening period, a 4-week induction period, a 24-week double-blind treatment period and a 28-week open-label treatment period, followed by a 4-week follow-up period and a follow-up visit.
sample size was calculated to be 552, including 140 subjects in the period of Phase IIb and 412 subjects in the period of 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(Independent Data Monitoring Committee) confirmed the RP3D ( Recommended phase 3 dosage ) 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.

Experimental: Supaglutide RP3D high dose
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
