The Efficacy and Safety of Liraglutide on Body Weight Loss in Obese and Overweight Patients

Phase 3

Completed

• Conditions: Overweight; Obese
• Interventions: Drug: Placebo; Drug: Liraglutide

• Registration Number: NCT04605861
• Lead Sponsor: Shanghai Zhongshan Hospital

Brief Summary

This is a multicenter, randomized, double-blind, placebo controlled trial to evaluate the effect and safety of Liraglutide Injection on body weight loss compared with placebo in obese or overweight adult patients with comorbidity of metabolic disorders.

Detailed Description

This is a multicenter, randomized, double-blind, placebo-controlled phase III clinical trial. The total study duration is 34\~36 weeks, including 2-week screening period, 6\~8-week dosage titration, 24-week stable treatment and 2-week safety follow-up period. Subjects with obesity or overweight with comorbidity of metabolic disorders receive subcutaneous injection of 3.0 mg Liraglutide or placebo every day. The primary endpoint is the change of body weight or the percentage of body weight loss greater than 5%. The changes of body weight between Liraglutide Injection group and placebo group will be compared. In the course of the trial, the subjects are weighted on fasting state. Blood samples are collected according to the protocol. All subjects receive lifestyle intervention, including a reductiong of calorie intake by 500 kcal a day and physical exercise.
