Clinical Trial Summary

This study will test the relative efficacy and effectiveness of the combination of naltrexone and bupropion (NB) medication as a treatment for binge-eating disorder (BED) in patients with obesity. This is a controlled test of whether, amongst non-responders to acute treatments, NB medication results in superior outcomes compared with placebo.

Description:

Obesity is a heterogeneous problem and research has highlighted the particular significance of a subgroup with binge-eating disorder (BED), the most prevalent formal eating disorder. Improved treatments for patients with obesity and BED are needed that can produce sustained clinical outcomes and promote weight loss. This study RCT will provide new and novel findings from a controlled test, amongst non-responders to acute treatments, whether Naltrexone/Bupropion medication results in superior and longer-term outcomes than placebo.

Type	Measure	Description	Time frame	Safety issue
Primary	Binge-Eating Frequency	Binge-eating frequency is a continuous variable of binge-eating episodes assessed using interview (Eating Disorder Examination interview). The Eating Disorder Examination uses a 28 day recall of eating behavior. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM -5) defines binge-eating as "eating, in a discrete period of time an amount of food that is definitely larger than most people would eat during a similar period of time and under similar circumstances and a sense of loss of control over eating during the episode." The number of episodes that meet this description will be counted and totaled.	From baseline interview at study enrollment to 3 months after the 12-week treatment.
