Cidara Therapeutics Provides Corporate Update and Reports First Quarter 2023 Financial Results

SAN DIEGO, May 11, 2023 — 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 reported financial results for the first quarter ended March 31, 2023 and provided an update on its corporate activities and product pipeline.

“The recently received $20.0 million milestone payment from Melinta Therapeutics following the U.S. Food and Drug Administration (FDA) approval of REZZAYO^TM (rezafungin for injection) further strengthened our balance sheet,” said Jeffrey Stein, Ph.D., president and chief executive officer of Cidara. “Importantly, we remain eligible to receive additional non-dilutive capital of up to approximately $47.1 million in development and regulatory milestones from our existing partnerships contingent on successful completion of activities planned for the next twelve months. We are now highly focused on advancing our Cloudbreak® drug-Fc conjugate (DFC) platform programs as we work to develop a new generation of immunotherapies to treat and prevent serious diseases, including multiple oncologic and autoimmune indications.”

Dr. Stein continued, “We expect to file an Investigational New Drug Application (IND) in 2024 for our first oncology DFC candidate, CD421, a potential first-in-class inhibitor of CD73. We are excited to share further insights into these promising ongoing programs at our planned R&D Day in the second half of this year.”

Recent Corporate Highlights

• Received $20.0 million milestone payment: In April 2023, Cidara announced receipt of a $20.0 million milestone payment from Melinta Therapeutics following the FDA approval of REZZAYO. Cidara remains eligible to receive additional non-dilutive capital of up to approximately $47.1 million in development and regulatory milestones from its existing partnerships contingent on successful completion of activities planned over the next twelve months. The Company’s current cash balance of $48.0 million and eligibility to potentially receive non-dilutive capital of up to approximately $47.1 million from existing partnerships over the next twelve months has the potential to extend its cash runway in the near-term.

First Quarter 2023 Financial Results

• Revenue totaled $26.0 million for the three months ended March 31, 2023, compared with $7.1 million for the same period in 2022.
