OBJECTIVE: To determine whether amphetamine extended-release oralsuspension (AMPH EROS) has an onset of effect at 30minutes postdose inchildren with ADHD.
METHODS: This randomized, double-blind, 2-treatment, 2-sequence, placebo-controlled crossover pilot study enrolled subjects aged 6 to 12 years withattention-deficit/hyperactivity disorder (ADHD) and ADHD-Rating Scale-5 scores of ≥90th percentile for sex and age. A dose of 5 to 20mg/day of AMPH EROS was determined during a 1-week open-label phase based on medication history, symptom control, and tolerability. Subjects completed a practice laboratory classroom then received one day of double-blind active drug or placebo each in random sequence during 2 double-blind laboratory classroom days. Subjects completed the first double-blind laboratory classroom session, returned to open label drug for 5days then crossed over on day 6 during a second double-blind laboratory classroom session. DB dose was fixed at AMPH EROS 15, 17.5, or 20mg . The primary endpoint was change from predose in the Swanson, Kotkin, Agler, M-Flynn, Pelham rating scale-combined score (SKAMP-C) at 30minutes postdose on two DB days. The key secondary endpoint was change from predose in the SKAMP-C score at 3hours postdose for AMPH EROS compared with placebo. Safety assessments included vital signs and adverse events.
RESULTS: Eighteen subjects were enrolled in the study (14 males and 4 females) with a mean age of 9 years. At both 30minutes and 3hours postdose, changes from baseline in SKAMP-C for AMPH EROS vs. placebo were statistically significant (p10%) during the open-label phase included upper respiratory tract infection, fatigue, upper abdominal pain, headache, decreased appetite, and affect lability.
CONCLUSIONS: AMPH EROS was effective in reducing ADHD symptoms at 30minutes postdose. AEs were mild or moderate and consistent with those of other extended-release amphetamines.Funding Acknowledgements: Support was provided by Tris Pharma, Inc.
