OBJECTIVE: To describe clinical characteristics and lisdexamfetamine dimesylate (LDX) treatment effects, based on gender and age, in adults diagnosed with moderate to severe binge eating disorder (BED).
METHODS: Adults diagnosed with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision-defined BED of moderate to severe severity were randomized to 12 weeks of dose-optimized LDX (50 or 70 mg) or placebo in 2 studies (conducted from November 26, 2012, to September 25, 2013 [study 1] and from November 26, 2012, to September 20, 2013 [study 2]). These post hoc analyses pooled data by gender (men vs women) and age (< 40 vs ≥ 40 years) across studies; reported P values are nominal (descriptive and unadjusted).
RESULTS: The pooled safety analysis and full analysis sets included 745 and 724 participants, respectively (men, n = 105 and n = 97; women, n = 640 and n = 627; < 40 years, n = 398 and n = 386; ≥ 40 years, n = 347 and n = 338). Across subgroups, most participants had a body mass index ≥ 30 kg/m² (63.0%-75.5%). The mean baseline number of binge eating days/wk was comparable across gender (4.6-4.7) and age (4.6-4.9), as was Yale-Brown Obsessive Compulsive Scale modified for Binge Eating (Y-BOCS-BE) total score (gender, 20.42-21.70; age, 21.40-21.63). Least squares mean (95% CI) treatment differences nominally favored LDX in all subgroups (all P < .001) for changes from baseline in binge eating days/wk at weeks 11-12 and in Y-BOCS-BE total score at week 12; no interactions by gender or age were reported. Consistent with the overall profile of LDX, across all subgroups LDX was associated with higher frequencies of treatment-emergent adverse events than placebo and with increases in blood pressure and pulse.
CONCLUSIONS: Across gender and age, participants exhibited comparable clinical characteristics and responses to dose-optimized LDX compared with placebo.
