FDA Approves Rezzayo (rezafungin for injection) for the Treatment of Candidemia and Invasive Candidiasis


In continuation of my update on rezafungin




Cidara Therapeutics, Inc.   and Melinta Therapeutics, LLC  announced   the U.S. Food and Drug Administration (FDA) approval of  Rezzayo (rezafungin for injection) for the treatment of candidemia and invasive candidiasis in adults with limited or no alternative treatment options. Rezzayo is the first new treatment option approved for patients with candidemia and invasive candidiasis in over a decade.

“The FDA approval of Rezzayo represents a significant milestone for Cidara, and for patients confronted with difficult-to-treat and often deadly candidemia and invasive candidiasis,” said Jeffrey Stein, Ph.D., president and chief executive officer of Cidara. “I am extremely proud of all of the Cidara employees who collectively advanced Rezzayo from preclinical development to NDA approval and am grateful to the many patients and healthcare teams who have participated in the clinical studies.”

George Thompson, M.D., principal investigator in the ReSTORE trial and professor of clinical medicine at the University of California, Davis, School of Medicine, added, “The FDA approval of Rezzayo is tremendous news for those of us who have been hoping for a new option to treat our patients with these deadly fungal infections. Based on the totality of clinical data generated, Rezzayo has the potential to simplify the management of invasive candidiasis and enhance the continuity of echinocandin care.”

The FDA approval of once-weekly Rezzayo was based on clinical data from Cidara’s global ReSTORE Phase 3 trial and supported by the STRIVE Phase 2 clinical trial and extensive non-clinical development program. In clinical studies, Rezzayo, dosed once-weekly, met the FDA and EMA primary endpoints, demonstrating statistical non-inferiority versus caspofungin, a current once-daily standard of care. In addition, overall rates of adverse events and serious adverse events were comparable in patients receiving Rezzayo and caspofungin, while rates of adverse events leading to study drug discontinuation were also similar for Rezzayo and caspofungin. Based on Qualified Infectious Disease Product (QIDP) designation, Rezzayo was approved under Priority Review.

Christine Ann Miller, president and chief executive officer of Melinta Therapeutics, added, “We are thrilled that the FDA has approved Rezzayo, and are firmly committed to offering this innovative therapy to address unmet medical needs and simplify the treatment for patients suffering from invasive Candida infections. We intend to leverage our expansive commercial infrastructure and experience launching anti-infective drugs into acute care settings. We are working closely with Cidara and anticipate bringing Rezzayo, a differentiated once-weekly treatment to patients, this summer.”

Last year, Melinta announced that it had acquired the exclusive rights to commercialize Rezzayo in the U.S. from Cidara. Cidara retains the rights to rezafungin in Japan and has licensed the commercial rights to Melinta Therapeutics in the U.S. and Mundipharma in all other geographies. The European Medicines Agency (EMA) accepted the marketing authorization application (MAA) for rezafungin in August 2022 and it is currently under review.

Cidara Therapeutics Announces FDA Acceptance for Priority Review of New Drug Application for Rezafungin for the Treatment of Candidemia and Invasive Candidiasis




Cidara Therapeutics, Inc.  , a biotechnology company developing long-acting therapeutics designed to improve the standard of care for patients facing serious diseases,  announced   the  FDA acceptance for filing and granted Priority Review to its New Drug Application (NDA) for rezafungin for the treatment of candidemia and invasive candidiasis. The FDA has assigned a Prescription Drug User Fee Act (PDUFA) target action date of March 22, 2023 enabled by rezafungin’s designation as a Qualified Infectious Disease Product (QIDP) and has indicated that it is currently planning to hold an advisory committee meeting to discuss the application. QIDP designation is reserved for antibacterial and antifungal drug candidates intended to treat serious or life-threatening infections. Rezafungin is a novel, once-weekly echinocandin antifungal being developed for the treatment of candidemia and invasive candidiasis, as well as for the prophylaxis of invasive fungal infections in patients undergoing allogeneic blood and marrow transplant.

“Today’s announcement is an important step forward for patients fighting difficult-to-treat and often deadly candidemia and invasive candidiasis, and represents a critical milestone for Cidara’s rezafungin development program,” said Jeff Stein, President, and CEO of Cidara Therapeutics. “The data generated across our Phase 2 and Phase 3 trials demonstrated that rezafungin could transform the current standard of care for the treatment of invasive Candida infections, and we are excited that rezafungin could potentially be the first new drug approved for this indication in over a decade.”

The NDA submission for rezafungin was supported by positive clinical data from the global ReSTORE Phase 3 and STRIVE Phase 2 clinical trials. Rezafungin dosed once-weekly demonstrated statistical non-inferiority versus caspofungin, the current standard of care, dosed once-daily, meeting the primary endpoints for both the FDA and the European Medicines Agency (EMA).

Cidara retains the rights to rezafungin in Japan and has licensed the commercial rights to Melinta Therapeutics in the U.S. and Mundipharma Medical in all other geographies.

About Rezafungin
Rezafungin is a novel once-weekly echinocandin being developed for both the treatment and prevention of serious fungal infections, such as candidemia and invasive candidiasis. The structure and properties of rezafungin are specifically designed to improve upon a clinically validated mechanism intended to enhance its efficacy and safety potential for patients. Cidara has completed a Phase 3 clinical trial with rezafungin for the first-line treatment of candidemia and/or invasive candidiasis (ReSTORE trial) and is currently conducting a second Phase 3 clinical trial of rezafungin for the prevention of invasive fungal disease in patients undergoing allogeneic blood and marrow transplantation (ReSPECT trial). Rezafungin has been designated a QIDP with Fast Track status by the FDA, and has been granted Orphan Drug Designation for its use in the treatment of invasive candidiasis in both the U.S. and EU.
