SUPN Supernus Pharmaceuticals Inc

Supernus Pharmaceuticals, Inc. (Nasdaq: SUPN), a biopharmaceutical company focused on developing and commercializing products for the treatment of central nervous system (CNS) diseases, today announced it has resubmitted its New Drug Application (NDA) for its apomorphine infusion device (SPN-830) for the continuous treatment of motor fluctuations (OFF episodes) in Parkinson’s disease (PD).

Supernus believes it has addressed the U.S. Food and Drug Administration’s (FDA) questions related to a Complete Response Letter (CRL) issued in April 2024 for the SPN-830 NDA. The CRL had indicated that the review cycle for the application was complete, but that two areas either required additional review by the FDA or additional information to be provided to the FDA. No clinical safety or efficacy issues were identified at that time as a requirement for approval. Supernus will continue to work closely with the FDA as it reviews the SPN-830 NDA.

“We continue to show our commitment to bring SPN-830 to the market and will support the FDA throughout the NDA review process,” said Jack Khattar, President and CEO of Supernus Pharmaceuticals. “If approved, we believe this novel therapy can be an important treatment option for PD patients and their families.”
