Supernus Talking with FDA on Two Submissions
Supernus Pharmaceuticals says it received a complete response letter from FDA for its NDA for SPN-812 (viloxazine HCl) to treat attention-deficit hyperactivity disorder in pediatric patients ages 8-17. A company statement says the primary issue cited in the FDA letter related to the firm’s in-house laboratory that conducts analytical testing. Supernus says the lab recently moved to a new location and says it will inform FDA that the NDA does not rely solely on the lab for product release. The company says it will discuss with FDA the steps required to resubmit the NDA.
The statement also says Supernus received a refusal to file letter from FDA for its NDA for SPN-830 (apomorphine infusion pump) for the continuous treatment of motor fluctuations in Parkinson’s disease. FDA indicated the NDA was not sufficiently complete to permit a substantive review, the letter said. The agency asked for certain documents and reports to be submitted in support of the application, Supernus says. It again says it will seek a meeting with FDA to clarify the issues and the steps required to resubmit the NDA.
