ABSTRACTObjective: To evaluate the long-term safety and effectiveness of lisdexamfetamine dimesylate (LDX) in the treatment of adults with attention-deficit/hyperactivity disorder (ADHD).Methods: Following a 4-week, placebo-controlled, double-blind trial, 349 adults with ADHD were enrolled into an open-label, single-arm study for up to 12 months. Treatment was initiated at 30 mg/day and titrated up to 70 mg/day at subsequent visits to achieve optimal effectiveness and tolerability. Safety assessments included adverse events inquiries, vital signs, and electrocardiograms while the primary effectiveness assessment was the ADHD Rating Scale (ADHD-RS) total score.Results: A total of 191 (54.7%) subjects completed the study. The most common treatment-emergent adverse events (TEAEs) were upper respiratory tract infection (21.8%), insomnia (19.5%), headache (17.2%), dry mouth (16.6%), decreased appetite (14.3%), and irritability (11.2%). Most TEAEs were mild to moderate in severity. At endpoint, small but statistically significant increases in pulse and blood pressure were noted. Significant improvements in mean ADHD-RS total scores were observed at week 1 and sustained throughout the study (P<.0001 at all postbaseline visits). At endpoint, the mean improvement from baseline ADHD-RS total score was 24.8 (P<.0001).Conclusions: LDX demonstrated a safety profile consistent with long-acting stimulant use and provided continued effectiveness in adults with ADHD for up to 12 months.

ABSTRACTIntroduction:Lisdexamfetamine dimesylate (LDX), a prodrug stimulant, is indicated for attention-deficit/hyperactivity disorder (ADHD) in children 6–12 years of age and in adults. In shortterm studies, once-daily LDX provided efficacy throughout the day. This study presented here was conducted to assess the long-term safety, tolerability, and effectiveness of LDX in 6- to 12-year-olds with ADHD.Methods:This open-label, multicenter, singlearm study enrolled children with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-Text Revision criteria for ADHD. Following 1-week screening and washout periods, subjects were titrated to LDX 30, 50, or 70 mg/day over 4 weeks and placed on maintenance treatment for 11 months. The ADHD Rating Scale and Clinical Global Impression-Improvement scale measured effectiveness.Results:Of 272 subjects receiving LDX, 147 completed the study. Most adverse events were mild to moderate and occurred during the first 4 weeks. There were no clinically meaningful changes in blood pressure or electrocardiographic parameters. From baseline to endpoint, mean ADHD Rating Scale scores improved by 27.2 points (P<.0001). Improvements occurred during each of the first 4 weeks, and were maintained throughout. Based on Clinical Global Impression-Improvement scale scores, >80% of subjects at endpoint and >95% of completers at 12 months were rated “improved.”Conclusion:Long-term 30, 50, and 70 mg/day LDX was generally well tolerated and effective in children with ADHD.
