Summary

This trial will test different treatments for people who have trouble controlling their eating and weight after weight-loss surgery. The treatments include behavior therapy to change eating habits and a combination of two medications to reduce cravings. The goal is to find out which approach works best for these patients.

Who is the study for?
Adults aged 18-70 who've had bariatric surgery (gastric bypass or sleeve gastrectomy) about six months ago, with a BMI of 30-50 (or ≥27 if they have certain health issues), experiencing weekly loss-of-control eating. They must be generally healthy, not on weight loss or contraindicated meds, and able to commit to up to 19 months in the study.
What is being tested?
The trial is testing how well behavioral weight loss strategies work compared to or combined with Naltrexone/Bupropion medication for controlling eating and managing weight after bariatric surgery. Participants will either receive the drug combo, placebo, or just behavioral therapy.
What are the potential side effects?
Naltrexone/Bupropion can cause nausea, headaches, constipation, dizziness, insomnia and dry mouth. There's also a risk for more serious effects like high blood pressure and seizures especially in those predisposed.

Other Research
The most common treatments for Binge Eating Disorder (BED) include pharmacological and behavioral therapies. Naltrexone/bupropion combines an opioid antagonist that reduces cravings (naltrexone) with a norepinephrine-dopamine reuptake inhibitor that aids in weight loss and mood regulation (bupropion). This combination helps manage the compulsive eating and emotional dysregulation seen in BED. Cognitive Behavioral Therapy (CBT) is another cornerstone treatment that addresses the dysfunctional thoughts and behaviors associated with binge eating. Other pharmacotherapies like lisdexamfetamine, a stimulant that reduces appetite, and topiramate, an anticonvulsant that decreases binge frequency, also play significant roles. These treatments are crucial as they target the underlying neurobiological and psychological factors of BED, providing comprehensive management of the disorder.
