Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to assess the impact of combination therapy with Naltrexone-Bupropion (NB) in the post-operative period of sleeve gastrectomy (SG). on a) weight loss, b) resolution of comorbidities and c) eating behaviors.

Researchers will compare SG-NB group with SG-placebo group to see if they experience significantly higher excess weight loss (EWL) at 12 and 24 months and if there is a significantly higher percentage of patients with an EWL above 50% in the SG-NB group versus in the SG-placebo group.

Participants will be randomized 1:1 to SG in combination with NB versus SG with placebo. Patients will be started one month after surgery on a progressive dose of Naltrexone/Bupropion extended-release or placebo. Duration of therapy will be 24 months.Both groups will benefit from behavioral and nutritional support.
