Completed · Phase 4

Conditions studied: Attention Deficit/Hyperactivity Disorder

In brief

The is a multicenter, dose-optimized, open-label, safety/ tolerability and pharmacokinetic (PK) study with Azstarys® in children 4 and 5 years of age with attention-deficit/hyperactivity disorder (ADHD). The primary objective is to determine the safety and tolerability of treating children 4 and 5 years-of-age with ADHD with Azstarys® for up 12 months. Approximately 100 subjects will be enrolled. Approximately 20 sites will participate.
