Efficacy and Safety of Dasotraline in Adults With Binge-Eating Disorder: A Randomized, Placebo-Controlled, Flexible-Dose Clinical Trial
Objective: Binge-eating disorder (BED) is the most prevalent eating disorder; however, few evidence-based treatments are available. The aim of this study was to evaluate the efficacy and safety of dasotraline, a novel dopamine and norepinephrine reuptake inhibitor, in adults with BED.
Methods: Patients with a DSM-5 diagnosis of BED (intent-to-treat sample, N = 315) were randomized to 12 weeks of double-blind treatment with once-daily, flexible doses (4, 6, or 8 mg/d) of dasotraline or placebo. Primary endpoint was change in diary-based assessment of number of binge-eating days per week at week 12. Key secondary endpoints included changes from baseline in Clinical Global Impressions-Severity of Illness scale (CGI-S) and Yale-Brown Obsessive Compulsive Scale Modified for Binge-Eating (YBOCS-BE) and percentage of subjects with cessation of binge eating in the final 4 weeks.
Results: Treatment with dasotraline was associated with a significantly greater reduction in binge-eating days per week at study endpoint (vs placebo; least squares mean [SE] difference score, −0.99 [0.17]; P < .0001; effect size [ES], 0.74). Significant endpoint improvement was observed for the 3 key secondary measures, CGI-S (P < .0001; ES, 0.95), YBOCS-BE (P < .0001; ES, 0.96), and 4-week cessation of binge eating (46.5% vs 20.6%; P < .0001). The most common adverse events in the dasotraline vs placebo groups were insomnia (44.6% vs 8.1%), dry mouth (27.4% vs 5.0%), decreased appetite (19.7% vs 6.9%), and anxiety (17.8% vs 2.5%). Discontinuation due to adverse events occurred in 11.3% of patients on dasotraline vs 2.5% on placebo.
Conclusions: The results of this placebo-controlled, double-blind study found dasotraline to be an efficacious, safe, and generally well-tolerated treatment for BED.
