HENDERSON, Nev.--(BUSINESS WIRE)--Jan 27, 2025--

Corstasis Therapeutics Inc. ( www.corstasis.com ), a clinical-stage MedTech pharmaceutical company developing innovative, practical therapies for fluid overload, today announced that the U.S. Food and Drug Administration (FDA) has accepted for review the New Drug Application (NDA) for its novel Bumetanide Nasal Spray (RSQ-777). The FDA has assigned a Prescription Drug User Fee Act (PDUFA) target action date of September 14, 2025.

This NDA acceptance represents a pivotal milestone for Corstasis Therapeutics, signifying the FDA’s determination that the application is sufficiently complete to move forward with a comprehensive review.

We look forward to working closely with the FDA throughout the review process.”
