Phase 3
Completed
Conditions
Type 2 Diabetes Mellitus (T2DM)
Interventions
Drug: GLP-1 receptor agonist
Drug: Placebo
Registration Number
NCT04504370
Lead Sponsor

Brief Summary

A randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of 24 once-weekly subcutaneous doses of PB-119 in Drug-naïve T2DM Subjects.

Detailed Description

The study included a maximum 2-week screening period, a 4-week single-blind introduction period, a 24-week double-blind treatment period, a 28-week open extension treatment period, and a 4-week safety follow-up period.

At the end of the single-blind entry period, eligible subjects were randomly assigned to two different administration groups in a 1:1 ratio and received a 24-week double-blind treatment.

All subjects who completed the double-blind treatment entered the open extension treatment phase.Open extension treatment with subcutaneous injection of 150μg PB-119 once a week for 28 weeks.

Safety follow-up was conducted 4 weeks after the end of treatment/completion of early exit visit in the open extension period.
