Evaluating Anti-Obesity Medications 6 Months After Metabolic Surgery

Official title

A Randomized, Double-Blind, Placebo-Controlled, Single-Center Study of Efsubaglutide Alfa in Patients Remaining Obese 6 Months After Metabolic Surgery

Overview

This clinical trial aims to evaluate the weight-loss efficacy and safety of efsubaglutide alfa in patients who remain obese 6 months after metabolic surgery.

Detailed description

This study investigates the effects of efsubaglutide alfa intervention in patients with a body mass index (BMI) ≥28 kg/m² six months after metabolic surgery, aiming to determine whether it facilitates weight normalization and remission of obesity-related comorbidities, thereby assessing the weight-loss and metabolic benefits of early efsubaglutide alfa application in post-metabolic surgery obesity management.

Interventions

• Drug Efsubaglutide Alfa Injection
  Efsubaglutide Alfa was injected daily in the morning before meals Subcutaneous injection at a dose of 1 mg/week in the first two weeks, increased to 3 mg/week in week 3, increased to 6 mg/week in week 5, up to 9 mg/2 week in week 13.
• Behavioral Diet and exercise guidelines
  Participants followed a science-based diet and exercise program intervention.

Primary outcome measures

• Change in %TWL from baseline to endpoint [Time frame: 24 weeks from enrollment]

Secondary outcome measures (7)

• Proportion of patients with different %TWL levels [Time frame: 24 weeks from enrollment]
• Proportion of patients with normal weight and overweight [Time frame: 24 weeks from enrollment]
• Change in body composition from baseline to endpoint across patient groups [Time frame: 24 weeks from enrollment]
• Remission Status of Obesity-Related Diseases [Time frame: 24 weeks from enrollment]
• Changes in blood pressure from baseline to endpoint [Time frame: 24 weeks from enrollment]
• Changes in fasting blood glucose from baseline to endpoint [Time frame: 24 weeks from enrollment]
• Change in HbA1c from baseline to endpoint across patient groups [Time frame: 24 weeks from enrollment]
