A Clinical Trial Evaluating TQF3250 Capsules in Patients With Type 2 Diabetes Mellitus and Overweight/Obesity

Starting soon · Phase 1 · Has a placebo group

Conditions studied: Type 2 Diabetes Mellitus Combined With Overweight or Obesity

In brief

This is a multicenter, randomized, double-blind, placebo-controlled Phase 1b clinical study designed to evaluate the safety, tolerability, pharmacokinetic profiles and preliminary efficacy of multiple oral doses of TQF3250 capsules in trial subjects with type 2 diabetes mellitus complicated with overweight or obesity. A total of 72 eligible subjects are planned to be enrolled in this study. Six treatment dose groups are established, including 4 mg, 8 mg, 12 mg, 24 mg, 32 mg and 40 mg, with a dose-escalation titration design. Each dose group will consist of 12 subjects. Eligible screened subjects will be randomized at a ratio of 10:2 (10 subjects receiving investigational drug and 2 subjects receiving placebo) to receive treatment with either TQF3250 capsules or matching placebo.
