The main purpose of this study is to assess the Efficacy and safety of HS-20094 in overweight and obese patients. The study will last up to approximately 52 weeks.

This is a phase Ⅲ, double-blind, randomised, placebo-controlled trial to assess the efficacy of HS-20094 in Chinese subjects with overweight or obesity. We enrolled adults (aged 18-65 years, both inclusive) with overweight (body-mass index [BMI] ≥24 kg/m2) accompanied by at least one obesity-related comorbidity or obesity (BMI ≥28 kg/m2) in China. Eligible participants were randomly assigned to receive once-weekly subcutaneous HS-20094 or placebo for 48 weeks. The co-primary endpoints were the percent change in bodyweight from baseline and the proportion of patients achieving weight loss≥5% from baseline after 48 weeks treatment.
