About

This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study, which aims to provide data on the efficacy and safety of HDM1002 tablets in adults with type 2 diabetes mellitus (T2DM) inadequately controlled with diet and exercise only

Full description

This phase 3, multi-center, randomized, double-blind, placebo-controlled, parallel group study aims to assess the efficacy and safety of HDM1002 tablets in adult participants with T2DM inadequately controlled with diet and exercise only. A total of 360 participants will be randomized in this study, and will be stratified according to baseline glycated hemoglobin (HbA1c) (≤ 8.5% or > 8.5%). Following the screening period to confirm eligibility up to 2-weeks, the study will consist of a 2-week placebo run-in period prior to randomization on Day 1. Eligible participants will be randomized in a 1:1:1 ratio to receive different doses of HDM1002 or placebo once daily for 52 weeks, followed by an approximate 4-week follow-up. During the treatment period, dose escalation will occur every 4 weeks until the target dose is reached. The evaluation of the primary endpoint will be conducted at Week 40

Enrollment: 360 estimated patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers
