First seen Jul 02, 2026 · Last updated Jul 02, 2026
Summary
This phase 3 trial tests whether a new formulation of dexmethylphenidate (CTx-1301) can improve attention and reduce ADHD symptoms in adults for up to 16 hours. Participants take an optimized dose (25, 37.5, or 50 mg) and complete math tests in a simulated classroom. The study compares the drug's effects against a placebo to see if it offers longer-lasting symptom control.
