Cidara Therapeutics and Melinta Therapeutics Announce Publication of Data from the Global Phase 3 Pivotal ReSTORE Trial of Rezafungin for the Treatment of Candidemia and Invasive Candidiasis in The Lancet

Publication details the efficacy and safety of rezafungin dosed once-weekly versus the current of care dosed once-daily

Rezafungin PDUFA target action date is scheduled for March 22, 2023

SAN DIEGO and PARSIPPANY, N.J., Nov. 28, 2022 — Cidara Therapeutics, Inc. (NASDAQ: CDTX) and Melinta Therapeutics, LLC today announced the peer-reviewed publication of data from the completed pivotal ReSTORE Phase 3 clinical trial evaluating the efficacy and safety of its once-weekly antifungal candidate rezafungin as a potential treatment for candidemia and invasive candidiasis. The data, published in The Lancet titled, “Rezafungin versus caspofungin for treatment of candidaemia and invasive candidiasis (ReSTORE): a multicentre, double-blind, double-dummy, randomised phase 3 trial,” demonstrate the statistical noninferiority of rezafungin dosed once-weekly, versus the current standard of care caspofungin, dosed once-daily.

“We are proud to have our Phase 3 clinical data published in one of world’s highest-impact academic medical journals, The Lancet, providing detailed results to the scientific and physician communities and showcasing the efficacy and safety of rezafungin,” said Jeffrey Stein, Ph.D., president and chief executive officer of Cidara. “These data demonstrate that rezafungin dosed once-weekly was noninferior to caspofungin dosed once-daily, an important achievement that has the potential to transform the treatment landscape for invasive fungal infections. We believe that rezafungin could have a significant impact on the lives of patients battling difficult-to-treat and often deadly Candida infections.”

Christine Ann Miller, president and chief executive officer of Melinta Therapeutics, added, “We are very pleased with the publication of the ReSTORE trial results in The Lancet, which like the Phase 2 study, demonstrate a consistent efficacy and safety profile of rezafungin as compared to caspofungin. We look forward to leveraging our established commercial infrastructure and experience in marketing infectious disease products, especially within the hospital and acute care settings, to make rezafungin available to physicians and their patients with candidemia and invasive candidiasis if approved.”

Melinta announced earlier this year that it had acquired the exclusive rights to commercialize rezafungin in the U.S. from Cidara.

Cidara reported positive topline results from ReSTORE in December 2021. Rezafungin met the primary endpoint for the U.S. Food and Drug Administration (FDA) New Drug Application (NDA) submission of all-cause mortality at Day 30, and also met the primary endpoint for the European Medicines Agency (EMA) Marketing Authorization Application (MAA) submission of global cure at Day 14. In the study, researchers evaluated one 400 milligram (mg) dose of rezafungin for the first week followed by 200 mg of rezafungin dosed once-weekly for up to four weeks in total. Rezafungin was generally well tolerated and had a similar safety profile to caspofungin.

The FDA has accepted for filing and granted Priority Review to Cidara’s 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 the application will be discussed during a scheduled meeting of the Antimicrobial Drugs Advisory Committee on January 24, 2023.

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