What this trial studies

This Phase 2 interventional study compares ALKS 7290 tablets to placebo in adults diagnosed with ADHD. Participants must meet DSM-5 criteria for ADHD and be medically stable, with specific symptom and BMI requirements. The study will assess safety and whether symptoms improve on ALKS 7290 compared with placebo, using standard assessments and monitoring. Enrollment is at Alkermes investigational sites in Little Rock, AR and Chino, CA.

Why it matters

Potential benefit: If successful, participants may experience improved ADHD symptoms and a favorable safety profile for ALKS 7290.

How similar studies have gone: Prior trials of similar agents have shown varying levels of symptom improvement; this study builds on that approach with a placebo comparison.
