A Study to Evaluate the Efficacy and Safety of CX11 Tablets in Overweight/Obese Participants

Completed · Phase 2 · Has a placebo group

Conditions studied: Obesity

In brief

This is a multicenter, randomized, double-blind, placebo-controlled Phase 2 clinical study: * To evaluate the efficacy of different dose levels of CX11 tablets in body weight reduction as compared to placebo. * To compare the changes of effects in weight and weight-related indicators at the visit time points. * To evaluate the tolerability and safety of different doses of CX11 tablets in overweight/obese participants. * To assess the pharmacokinetics (PK) of different doses of CX11 tablets in overweight/obese participants. Overweight/obese participants who are successfully screened will be randomized in a 1:1:1:1:1 ratio to different doses of CX11 tablets or placebo. All participants will enter a 2-week follow-up period after 36 weeks of treatment for safety observation.
