Exhibit 99.1
CORMEDIX Therapeutics AnnounceS POSITIVE Topline Results from PHASE III respect TriaL assessing Rezzayo® for the PROPHYLAXIS ofinvasive fungal diseases in ALLOGENEIC Haematopoietic Stem Cell Transplantation PATIENTS
– The study primary endpoint was met, showing non-inferiority vs. standard antimicrobial regimen in fungal free survival at Day 90 –
– Study showed favorable benefit for toxicity related discontinuations and drug-drug interactions –
– Rezafungin was well tolerated, with a safety profile comparable to standard antimicrobial regimens –
Parsippany, NJ – April 27, 2026 – CorMedix Therapeutics (Nasdaq: CRMD) today announced positive Phase III topline results from the global ReSPECT clinical trial evaluating REZZAYO® (rezafungin for injection) for prophylaxis of invasive fungal diseases (IFDs) in adult patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT).
The ReSPECT Phase III study, one of the largest anti-fungal multicenter, randomized, double-blind studies 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, including infections caused by Candida, Aspergillus, and Pneumocystis, in adults undergoing allogeneic HSCT. Patients undergoing allogeneic blood and marrow transplantation face prolonged periods of immunosuppression and routinely require extended antifungal prophylaxis, representing a setting where differentiated dosing, improved side effect profile, and reduced DDI is beneficial, and comparable efficacy is expected.
The ReSPECT study met its primary endpoint for FDA and EMA for fungal-free survival at Day 90 showing non-inferiority vs. SAR, with 60.7% fungal-free survival at Day 90 for rezafungin compared to 59.0% for standard antimicrobial regimen. This demonstrates that rezafungin’s differentiated pharmacokinetics/pharmacodynamics (PK/PD) profile was comparable to the standard antimicrobial regimen (SAR) in reducing the incidence of invasive fungal infections in a high-risk patient population. Rezafungin was well tolerated, with a safety profile showing a favorable benefit/risk profile for immunocompromised patients.
The Phase III study topline results demonstrated comparable efficacy against invasive infections from candida, aspergillusand pneumocystisin both therapeutic arms, as well as comparable mortality. In addition, results showed a favorable profile in multiple secondary endpoints, most notably treatment emergent adverse events leading to dose reduction, interruption or withdrawal of study drug, and treatment emergent adverse events leading to study discontinuation.
“We believe this positive outcome of the Phase III ReSPECT study meaningfully strengthens REZZAYO’s long-term potential value proposition to patients and clinicians,” said Joseph Todisco, Chairman & Chief Executive Officer of CorMedix Therapeutics. “Preliminary topline results for ReSPECT demonstrate clinical efficacy in prevention against all three measured pathogens, as well as positive differentiation in certain safety related secondary endpoints, specifically drug-drug interactions and toxicity related discontinuations, which positions REZZAYO well to become an attractive alternative to the standard anti-fungal regimen, if approved by FDA for an expanded indication of prophylaxis of IFD. Our deepest gratitude goes out to the patients, their caregivers, investigators and the study staff whose dedication and participation enabled this compelling clinical outcome.”
This clinical trial has been sponsored by Mundipharma. Mundipharma has commercial rights to rezafungin outside the U.S. Mundipharma has partnered with Melinta Therapeutics, LLC, a wholly owned subsidiary of CorMedix for US distribution of rezafungin. The companies anticipate a pre-NDA submission meeting with FDA in the coming months, followed by a target submission of a supplemental New Drug Application (sNDA) to the FDA in 2H26 based on the ReSPECT results.
