• U.S. launch of REZZAYO by Melinta expected in mid-2023 
• Company eligible to receive up to an additional $47 million in milestones from multiple existing partnerships based on successful completion of activities planned over the next year 

SAN DIEGO, April 24, 2023 (GLOBE NEWSWIRE) -- Cidara Therapeutics, Inc. (Nasdaq: CDTX), a biotechnology company developing long-acting therapeutics designed to save lives and improve the standard of care for patients facing serious diseases, today announced receipt of a $20 million milestone payment from Melinta Therapeutics following the U.S. Food and Drug Administration (FDA) approval of REZZAYO™ (rezafungin for injection), a novel, once-weekly echinocandin antifungal approved for the treatment of candidemia and invasive candidiasis.

Last month, REZZAYO became the first new FDA-approved echinocandin in over a decade for once weekly use in adults with limited or no alternative treatment options. The approval was based on positive data from Cidara’s global ReSTORE Phase 3 trial and supported by the STRIVE Phase 2 clinical trial and extensive non-clinical development program. Last year, Melinta acquired exclusive rights to commercialize REZZAYO in the U.S. from Cidara.

“We look forward to Melinta bringing REZZAYO to the U.S. market, which is in urgent need of new treatment options for patients with often deadly fungal infections. Receipt of this milestone payment is an important next step in redirecting Cidara’s focus to our Cloudbreak^® drug-Fc conjugate (DFC) programs in oncologic and autoimmune indications,” said Jeffrey Stein, Ph.D., president and chief executive officer of Cidara. “With the $20 million milestone payment from Melinta, Cidara remains eligible to receive additional non-dilutive capital of up to approximately $47 million in development and regulatory milestones from our existing partnerships based on successful completion of activities planned for the next year. The Company’s 2022 year-end cash balance of $32.7 million, this $20 million milestone payment from Melinta, and proceeds from the recent financing and at-the-market offerings, along with the eligibility to receive non-dilutive capital of approximately $47 million from existing partnerships over the next year, has the potential to extend our cash runway without the need to rely on equity markets to raise additional capital in the near-term.”

Cidara is currently advancing its Cloudbreak^® DFC program in an ongoing Phase 2a trial being conducted in collaboration with Janssen that is evaluating the pre-exposure prophylactic activity of CD388 against the H3N2 influenza A virus strain. The Company recently announced positive interim efficacy and safety data from the Phase 2a study. Cidara is additionally advancing its first oncology DFC candidate, CD421, a first-in-class inhibitor of CD73, with an IND anticipated in 2024.
