Supernus Provides Regulatory Update on SPN-830

ROCKVILLE, Md., Oct. 10, 2022 (GLOBE NEWSWIRE) -- Supernus Pharmaceuticals, Inc. (Nasdaq: SUPN), a pharmaceutical company focused on developing and commercializing products for the treatment of central nervous system (CNS) diseases, today announced that the U.S. Food and Drug Administration (FDA) has issued a Complete Response Letter (CRL) for the SPN-830 New Drug Application (NDA). SPN-830 is an investigational apomorphine infusion device under review for the continuous treatment of motor fluctuations (OFF episodes) in Parkinson’s disease (PD).

The CRL requires additional information and analysis related to the infusion device and drug product across several areas of the NDA including, but not limited to, labeling, product quality and manufacturing, device performance and risk analysis. In addition, the FDA mentions that approval of the NDA requires inspections that could not be completed in a timely manner due to COVID-19 travel restrictions. The CRL does not request additional efficacy and safety clinical studies. Supernus will continue to work closely with the FDA to address all questions, and when possible, to provide clarity regarding the potential timing of a resubmission of the NDA. The FDA has made an initial determination that the amendment to the Company’s application in response to the CRL will be subject to a Class 2, or six-month, review timeline.

“SPN-830 remains a key priority for Supernus as there is a need to provide a minimally invasive therapy for PD patients who are experiencing motor fluctuations not adequately controlled with current treatment options,” said Jack Khattar, President and CEO of Supernus. “We are committed to PD patients and to working with the FDA to address the CRL issues so that we can put the NDA back on track towards potential U.S. approval.”
