Supernus Resubmits NDA for ADHD Drug

Supernus Pharmaceuticals has resubmitted its NDA for SPN-812 for treating attention deficit/hyperactivity disorder (ADHD) in pediatric patients. In 11/2020, FDA issued a complete response letter, citing Supernus’ in-house laboratory that conducts analytical testing, which recently moved to a new location. In the NDA resubmission Supernus says it removed reference to its in-house laboratory and addressed other CRL issues. The company expects the agency will classify the resubmission as Class I (two-month review) or Class II (six-month review).

 

Meanwhile, in 12/2020, Supernus announced positive results from a Phase 3 study for SPN-812 in adults with ADHD. It plans to submit a supplemental NDA to the agency for treating this patient population in the second half of this year, assuming approval for pediatric-use submission.
