Официальное название

A Multicenter, Randomized, Double-Blind, Placebo-Controlled Phase III Clinical Study to Evaluate the Efficacy and Safety of DA-302168S Tablets in Overweight/Obese Participants

Обзор

This study is a multicenter, randomized, double-blind, placebo-controlled Phase III clinical study aimed at evaluating the efficacy, safety, and pharmacokinetic (PK) characteristics of DA-302168S tablets in overweight or obese participants in China.

Подробное описание

This study will be divided into three phases: a screening period (up to 2 weeks), a treatment period (52 weeks), and a safety follow-up period (2 weeks). The study plans to enroll approximately 840 participants. Eligible participants will be randomly assigned in a 1:1:1 ratio to the 10 mg dose group, the 20 mg dose group, or the placebo group, with each dose group planned to enroll about 280 participants. During the treatment period, all participants should adhere to dietary and exercise control, with guidance on diet and energy intake provided by authorized nutritionists or investigators.
