Study Overview
Brief Summary
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.

Outcomes
Primary Outcomes
Change in %TWL from baseline to endpoint
Time Frame: 24 weeks from enrollment
%TWL = (\[baseline weight - weight at follow-up\]/baseline weight) × 100%. The measurement of body weight is in kilograms. %TWL represents the percentage of total weight loss, measured in percent. This indicator reflects the percentage of weight loss from the baseline. The mean and standard deviation of %TWL were calculated for subjects within each group. Subsequently, intergroup comparisons were performed to calculate p-values. If p \< 0.05, pairwise comparisons were further conducted. Based on the final results, the differences in weight loss among groups were evaluated.
Secondary Outcomes
- Proportion of patients with different %TWL levels(24 weeks from enrollment)
- Proportion of patients with normal weight and overweight(24 weeks from enrollment)
- Remission Status of Obesity-Related Diseases(24 weeks from enrollment)
- Change in body composition from baseline to endpoint across patient groups(24 weeks from enrollment)
- Changes in blood pressure from baseline to endpoint(24 weeks from enrollment)
- Changes in fasting blood glucose from baseline to endpoint(24 weeks from enrollment)
- Change in HbA1c from baseline to endpoint across patient groups(24 weeks from enrollment)
