FDA Accepts NDA for Once-Daily ADHD Drug

Share

FDA has accepted for review a Cingulate NDA for CTx-1301 (dexmethylphenidate), a once-daily stimulant designed to treat attention-deficit/hyperactivity disorder in children and adults. CTx-1301 uses Cingulate’s precision timed release technology to deliver three timed doses of dexmethylphenidate throughout the day, according to the company. The agency has set a 5/31/2026 user fee review action target date.

The NDA was submitted under FDA’s 505(b)(2) regulatory pathway that allows reliance on data from approved drugs to support approval. The company says its NDA is also supported by Phase 3 trials showing significant and sustained improvements across key efficacy measures, including the Permanent Product Measure of Performance and Adult ADHD Investigator Symptom Rating Scale in adults, and the ADHD Rating Scale-5 and Clinical Global Impression scale in children.

Cingulate says no serious treatment-emergent adverse events were reported, and CTx-1301’s safety profile was consistent with other long-acting methylphenidate products.
