The Food and Drug Administration has accepted for review the supplemental New Drug Application for viloxazine extended-release for the treatment of attention-deficit hyperactivity disorder in adults.

The application is supported by data from a multicenter, randomized, double-blind, placebo-controlled phase 3 trial (ClinicalTrials.gov Identifier: NCT04016779), which assessed the efficacy and safety of viloxazine in 374 adults with ADHD. The trial included a 2-arm flexible dose design, in which patients were randomly assigned to receive a daily dose of viloxazine starting with 200mg up to 600mg or placebo. 

Results showed that treatment with viloxazine met the primary endpoint demonstrating statistically significant improvements in ADHD symptoms compared with placebo at week 6 as assessed by the adult ADHD Investigator Symptom Rating Scale (-15.5 point change vs -11.7 point change, respectively; P =.004). Treatment with viloxazine was also associated with statistically significant improvement vs placebo on the Clinical Global Impression – Severity of Illness Scale at week 6 (P =.0023).
