This randomized, placebo-controlled, Phase 2, single site, pilot study will evaluate the developmental impact of combined medication and behavioral treatment (COMB) versus placebo and behavioral treatment (BEH) in children with comorbid ASD +ADHD, who are between 36 and < 132 months of age. The active medication treatment will be an orally dissolvable, extended release amphetamine preparation (Adzenys-XR-ODT) administered from weeks 0-~11 and carefully titrated to the optimal dose using an algorithm that considers adverse events and improvement in attention symptoms with a flexible dose range of 1.55mg - 18.6mg/day. The target dose is 12.4mg/day. A placebo, matched to the active medication, will be titrated and adjusted using the same algorithm in the BEH arm. The provided behavioral treatment will be eight ~ hour long parent child therapy sessions of ESDM influenced parent coaching. Approximately 48 participants will be randomly assigned to either the COMB or BEH treatment arms. To account for possible differences in attrition due to potential poor tolerability of Adzenys-XR-ODT, participants will be randomized in a 7 COMB to 6 BEH ratio. Treatment assignment will be provided by the Data Management and Analysis Core (DMAC)using computer generated algorithms. The primary analyses will compare changes in outcomes between weeks 0 and 11 weeks. Exploratory analyses will explore changes between weeks 0 and 24. The primary outcome measure is change in amount and quality of joint engagement between the child and the parent during a semi-structured, 6 minute parent child interaction task (PCIT), which reflects the core symptom domain targeted by P-ESDM: social communication. Our key secondary outcomes will be changes in 1) the mean of the interview version of the VABS-3 socialization subscale and communication subscale standard scores and 2) clinician ratings of ADHD symptoms using the preschool ADHD-RS. We will also assess the safety and tolerability of Adzenys-XR-ODT compared to placebo.
