– Enrollment Completed in Ongoing Phase III ReSPECT Study in Prophylaxis of Fungal Infections in Adult Patients Undergoing Allogeneic Blood and Marrow Transplant –

– Topline Results from ReSPECT Study Expected in 2Q 2026 –

BERKELEY HEIGHTS, N.J., Sept. 29, 2025 (GLOBE NEWSWIRE) — CorMedix Inc. (“CorMedix”) (Nasdaq: CRMD), a biopharmaceutical company focused on developing and commercializing therapeutic products for life-threatening diseases and conditions, today announced completion of enrollment for the ongoing, global Phase III ReSPECT trial evaluating the efficacy of REZZAYO® (rezafungin), a single-agent echinocandin in the prevention of Candida, Aspergillus, and Pneumocystis infection in patients undergoing allogeneic blood and marrow transplantation (BMT). This clinical trial has been sponsored by Mundipharma, located in the United Kingdom.  The US distribution rights for REZZAYO were licensed under a strategic collaboration agreement with Melinta Therapeutics, LLC, a wholly owned subsidiary of CorMedix.

“Completing enrollment for the Phase III ReSPECT study represents an important step toward our goal of seeking FDA approval for REZZAYO in the prophylaxis of invasive fungal disease in adult patients receiving BMT,” said Joseph Todisco, CEO of CorMedix. Mr. Todisco continued, “While we have just recently closed our acquisition of Melinta Therapeutics, we believe that a prophylaxis indication for REZZAYO represents a significant growth opportunity for CorMedix, given the critical unmet need in this high-risk patient population. We look forward to sharing topline results from this study next year.”

The ReSPECT clinical trial is a Phase III, multicenter, randomized, double-blind study evaluating the efficacy and safety of once-weekly rezafungin (REZZAYO) versus a standard antimicrobial regimen (SAR) for the prevention of invasive fungal diseases (IFDs) in adults undergoing allogeneic BMT. Participants in the experimental arm receive a 400 mg loading dose of rezafungin in week one, followed by 200 mg weekly for 13 weeks, along with oral placebos matching the SAR components. The primary endpoint is fungal-free survival at day 90, with secondary objectives including incidence of IFD, discontinuation due to toxicity, and mortality adjusted for comorbidities.

INDICATIONS AND USE

REZZAYO is an echinocandin antifungal indicated in patients 18 years of age or older who have limited or no alternative options for the treatment of candidemia and invasive candidiasis. Approval of this indication is based on limited clinical safety and efficacy data. REZZAYO has not been studied in patients with endocarditis, osteomyelitis, and meningitis due to Candida.

REZZAYO may cause infusion-related reactions, including flushing, sensation of warmth, urticaria, nausea, or chest tightness. If these reactions occur, slow or pause the infusion. REZZAYO may cause photosensitivity. Advise patients to use protection from sun exposure and other sources of UV radiation. Abnormalities in liver tests have been seen in clinical trial patients treated with REZZAYO. Monitor patients who develop abnormal liver tests and evaluate patients for their risk/benefit of continuing REZZAYO therapy.
