CU-20401

This study is a Phase Ib/II clinical study. Phase 1b was a single-center, nonrandomized, single-arm study to evaluate the safety, PK profile, preliminary efficacy, and immunogenicity of different groups (SC) of CU-20401 in the submental fat accumulation population. Phase 2 is a multicenter, randomized, placebo parallel-controlled study to evaluate the safety, efficacy, and immunogenicity of the preferred group (SC) of CU-20401 in a submental fat accumulation population.

This is an open-label, Part I/2/3/4 Phase 1 clinical study to evaluate the safety, tolerability, pharmacokinetics, and immunogenicity of a single subcutaneous injection of CU-20401 in healthy Chinese population, and to recommend an appropriate dose for subsequent clinical studies.
