A Phase 3 Study to Evaluate Efficacy and Safety of HDM1002 Tablets in Adults With Type 2 Diabetes Mellitus

A Phase 3, Randomized, Double-blind, Active-Controlled, Parallel-Group Study to Evaluate the Efficacy and Safety of HDM1002 Tablets Compared With Dapagliflozin in Subjects With Type 2 Diabetes Mellitus Inadequately Controlled on Metformin

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

Study Overview

• Status: Recruiting
• Conditions: Type 2 Diabetes
• Intervention / Treatment: Drug: HDM1002 100 mg; Drug: HDM1002 200 mg; Drug: HDM1002 400 mg; Drug: Dapagliflozin (DAPA)

Detailed Description

This phase 3, multi-center, randomized, double-blind, active-controlled, parallel group study aims to assess the efficacy and safety of HDM1002 tablets in adult participants with T2DM inadequately controlled on metformin monotherapy. A total of 800 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 4-week metformin run-in period prior to randomization on Day 1. Eligible participants will be randomized in a 1:1:1:1 ratio to receive different doses of HDM1002 or dapagliflozin 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.
