– 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, NJ – September 29, 2025 – 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. About REZZAYO® REZZAYO (rezafungin for injection) is a next generation echinocandin approved in the United States for the treatment of candidemia and invasive candidiasis in adults. There are an estimated 50,000 cases of candidemia and invasive candidiasis each year in the U.S. REZZAYO is currently being studied for the prevention of invasive fungal diseases in adults undergoing allogeneic BMT. CorMedix estimates that there are an approximately 130,000 patients that could constitute the addressable market for antifungal prophylaxis in the U.S. and estimates an implied total addressable market (“TAM”) of over $2B in this market segment. REZZAYO has orphan drug exclusivity through 2035 and patent coverage through 2038 in the U.S. About CorMedix CorMedix Inc. is a biopharmaceutical company focused on developing and commercializing therapeutic products for the prevention and treatment of life-threatening conditions and diseases.

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. IMPORTANT SAFETY INFORMATION REZZAYO is contraindicated in patients with known hypersensitivity to rezafungin or other echinocandins. 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. Most common adverse reactions (incidence ≥5%) are hypokalemia, pyrexia, diarrhea, anemia, vomiting, nausea, hypomagnesemia, abdominal pain, constipation, and hypophosphatemia.

- Findings highlight the potential of antibiotic-eluting bioenvelopes to transform cardiac implantable electronic device (CIED) pocket management - GAITHERSBURG, Md., Sept. 16, 2025 (GLOBE NEWSWIRE) -- Elutia Inc. (Nasdaq: ELUT) (“Elutia” or the “Company”), a pioneer in drug-eluting biomatrix technologies, today announced the publication of clinical and preclinical data supporting the clinical utility of a biologic envelope that secures cardiac implantable electronic devices (CIEDs), promotes tissue remodeling, and addresses bacterial colonization through localized antibiotic delivery. The data are published in the current issue of Frontiers in Cardiovascular Medicine. The publication includes data from the HEAL study (NCT04645173), a multicenter observational clinical evaluation of patients undergoing CIED reoperations. This study found that patients previously implanted with an engineered extracellular matrix (ECM) envelope had 43% lower overall procedural difficulty, including 46% easier generator mobilization and 41% easier lead mobilization compared with patients previously implanted without envelopes or with non-biologic envelopes. “These results suggest that biologic envelopes not only facilitate placement and stabilize the device initially but also preserve surgical access to the pocket over time,” said Dr. Benjamin D’Souza, Associate Professor of Medicine at the University of Pennsylvania and Section Chief of Cardiac Electrophysiology at Penn Presbyterian Medical Center. “That is especially relevant for patients likely to undergo future reinterventions.” The publication also details preclinical studies showing complete eradication of bacterial inoculates commonly implicated in CIED-related complications. The antibiotic-eluting envelope eliminated pathogens, such as MRSA, while maintaining regenerative function. Pharmacokinetic assessments confirmed sustained local antibiotic concentrations for up to two weeks. “The drug-eluting biomatrix technology developed by Elutia is an effective solution for two long-standing CIED procedural challenges — eliminating the bacteria that can cause near-term, post-operative complications and reducing long-term procedural difficulties,” said Dr. Michelle LeRoux Williams, PhD, Chief Scientific Officer at Elutia. “Elutia is committed to transforming our drug-eluting biomatrix technologies into innovative products that address real-world clinical needs and improve patient outcomes.” The combination of regenerative ECM and broad-spectrum, synergistic antibiotics, like rifampin and minocycline, is a powerful platform for future drug-eluting biologics—particularly in surgical settings where tissue remodeling and infection control intersect. Building on this foundation, Elutia is advancing a next-generation pipeline targeting higher-risk procedures, such as breast reconstruction where one in three patients suffer serious complications after reconstruction. This research lays the groundwork for a future in which the body’s healing response is managed as carefully as the device itself. About ElutiaElutia develops and commercializes drug-eluting biomatrix products to improve compatibility between medical devices and the patients who need them. With a growing population in need of implantable technologies, Elutia’s mission is humanizing medicine so patients can thrive without compromise. For more information, visit www.Elutia.com.
