Who could benefit from this research

Could help

Adults who have experienced weight regain after bariatric surgery and are eligible for pharmacotherapy plus lifestyle counseling.

Less likely to help

Those who do not respond to pharmacotherapy or have contraindications to the study medications may not experience benefits.

What this research studies

After bariatric surgery, many patients regain weight over time. This trial tests a combination of weight-loss drugs and ongoing diet and activity coaching to see if it can prevent regain. It uses a SMART design to adjust treatment based on early response, enrolling 120 adults at risk of regain. All participants receive ongoing diet and lifestyle counseling, regardless of group. The study aims to identify effective pharmacotherapy strategies to sustain the benefits of bariatric surgery.

Why it matters

Potential benefit: If successful, patients could have a proven option to maintain weight loss after bariatric surgery and improve related health outcomes.

How similar studies have gone: Prior small studies suggest potential benefits of drug-assisted weight management, but robust RCT data for post-bariatric weight regain are limited.
