Supernus Pharmaceuticals receives CRL for Parkinson's treatment

Supernus Pharmaceuticals, Inc. (NASDAQ: SUPN) has provided a regulatory update for its investigational apomorphine infusion device, SPN-830, aimed at treating motor fluctuations in Parkinson's disease (PD). The U.S. Food and Drug Administration (FDA) has issued a complete response letter (CRL) in response to the new drug application (NDA) for SPN-830, indicating that the application is not ready for approval in its present form.

The CRL mentions two areas that require additional review by the FDA or additional information to be provided. The first area relates to product quality, for which the company has recently submitted additional data to the FDA. The second area pertains to the master file for the infusion device, which is proprietary to the device manufacturer. The FDA's preapproval inspection of the device manufacturer's facility in February 2024 was successful, with no clinical safety or efficacy issues identified as a requirement for approval.

Supernus Pharmaceuticals remains committed to bringing SPN-830 to the market and plans to work with the FDA to address the CRL and successfully resubmit the NDA for SPN-830.
