Cidara Therapeutics Announces Approval of REZZAYO by the MHRA for the Treatment of Invasive Candidiasis in Adults
- The UK MHRA approval follows approvals by the U.S. FDA and the European Commission
- Cidara is entitled to receive a milestone payment of approximately $2.8 million from Mundipharma
SAN DIEGO, Jan. 29, 2024 (GLOBE NEWSWIRE) -- Cidara Therapeutics, Inc. (Nasdaq: CDTX), a biotechnology company developing therapies designed to save lives and improve the standard of care for patients facing serious diseases, today announced that the United Kingdom (U.K.) Medicines and Healthcare products Regulatory Agency (MHRA) has approved REZZAYO (rezafungin acetate) for the treatment of invasive candidiasis in adults.
“Today’s announcement by the MHRA expands treatment options to even more patients suffering from life-threatening invasive candidiasis infections globally,” said Taylor Sandison, M.D. M.P.H., Chief Medical Officer at Cidara. “Our team, in partnership with Mundipharma, is proud to help bring the first new treatment option in 15 years to patients with this disease.”
This approval comes after positive results from the ReSTORE Phase III clinical trial, which demonstrated statistical non-inferiority for weekly-dosed rezafungin compared to the standard of care, daily-dosed caspofungin. Rezafungin’s safety and efficacy are further supported by the STRIVE Phase II clinical trials and an extensive nonclinical development program. Rezafungin is already approved by the United States Food and Drug Administration (FDA) and European Commission (EC).
Cidara Therapeutics has partnered with Mundipharma, which has commercial rights to rezafungin outside the U.S. and Japan. The company is entitled to receive a $2.8 million milestone payment from Mundipharma for the MHRA approval.

About invasive candidiasis
Invasive candidiasis (IC) 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, the mortality rate for patients with invasive candidiasis is as high as 40%. IC is characterized as a severe, life-threatening systemic Candida infection of the bloodstream and/or deep/visceral tissues, known as candidemia and deep-seated tissue candidiasis.
About REZZAYO® (rezafungin for injection)
REZZAYO (rezafungin for injection) is a novel once-weekly echinocandin approved in the United States for the treatment of candidemia and invasive candidiasis in adults. REZZAYO is currently being studied for the prevention of invasive fungal diseases in adults undergoing allogeneic blood and marrow transplantation. The structure and properties of REZZAYO are specifically designed to improve upon a clinically validated mechanism.
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.
