Brief Summary

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

This study will test the effectiveness of lisdexamfetamine (LDX) medication as a maintenance therapy for the treatment of binge-eating disorder (BED) in patients with obesity. This is a controlled test of whether, amongst responders to acute treatments, LDX medication results in superior maintenance and longer-term outcomes compared with placebo.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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 (maintenance stage) RCT will provide findings from a controlled test, amongst responders to acute treatments, whether LDX medication results in superior maintenance and longer-term outcomes than placebo. This is one of the few RCTs for BED of medication with follow-up after medication discontinuation.
