PARSIPPANY, N.J., Oct. 19, 2026 (GLOBE NEWSWIRE) — CorMedix Therapeutics (Nasdaq: CRMD) today announced that the U.S. Food and Drug Administration (FDA) has accepted for filing the supplemental New Drug Application (sNDA) seeking approval of REZZAYO® (rezafungin for injection) for the prophylaxis of invasive fungal disease. The sNDA was submitted by Mundipharma, CorMedix’s global development partner, and the FDA has granted Priority Review with a Prescription Drug User Fee Act (PDUFA) target action date in Q1 2027. The sNDA is supported by the Phase III ReSPECT pivotal study, for which CorMedix announced positive topline results in April. ReSPECT evaluated the efficacy and safety of once weekly rezafungin (rezafungin acetate) compared with a standard antimicrobial regimen (SAR) for the prophylaxis of invasive fungal diseases in adults undergoing allogeneic HSCT. If REZZAYO is approved for this new indication, CorMedix is targeting to begin promotional efforts beginning in H2 2027.

“The FDA’s acceptance of this supplemental application for Priority Review is an important regulatory milestone for CorMedix, REZZAYO, and for patients who remain at risk for invasive fungal disease,” said Joseph Todisco, Chairman & Chief Executive Officer of CorMedix. “We are grateful to the patients, investigators and clinicians who participated in ReSPECT and to our partner, Mundipharma, for their contributions in reaching this point. We look forward to working closely with Mundipharma in the coming months ahead of FDA’s action date and will begin to prepare for a potential promotional launch in the second half of 2027.”

About rezafungin

REZZAYO® (rezafungin for injection) is a once-weekly echinocandin antifungal approved by the FDA for the treatment of candidemia and invasive candidiasis in adults and pediatric patients 12 years of age or older who have limited or no alternative options for treatment. Invasive candidiasis continues to be an area of significant unmet need, especially for critically ill patients in hospitals and patients with compromised immune systems. Despite a number of available treatments, mortality rates for patients with invasive candidiasis have been reported to be as high as 40%.

Rezafungin has been studied for the prophylaxis of invasive fungal diseases in adults undergoing allogeneic HSCT. REZZAYO is not approved by the FDA for the prophylaxis of invasive fungal diseases, and its safety and efficacy for that use have not been established. Rezafungin has orphan drug exclusivity through 2035 and patent coverage through 2038 in the U.S.

REZZAYO® is a Registered Trademark of Mundipharma, used under license by Melinta Therapeutics LLC, a wholly owned subsidiary of CorMedix Inc. in the US.
