Cidara Therapeutics Provides Corporate Update and Reports First Quarter 2022 Financial Results

SAN DIEGO, May 11, 2022 — Cidara Therapeutics, Inc. (NASDAQ: CDTX), a biotechnology company developing long-acting therapeutics designed to improve the standard of care for patients facing serious diseases, today reported financial results for the first quarter ended March 31, 2022 and provided an update on its corporate activities and product pipeline.

“We continue to advance our pipeline of Cloudbreak DFC product candidates,” said Jeffrey Stein, Ph.D., president and chief executive officer of Cidara. “Notably, we achieved a significant milestone in our Cloudbreak program in the first quarter with the dosing of the first cohort of healthy volunteers in our Phase 1 trial of CD388, Cidara’s lead influenza drug-FC conjugate (DFC), designed for the prevention of seasonal and pandemic influenza. The Phase 1 study is progressing on schedule and we look forward to providing further updates on this key clinical program that we are developing with our partner, Janssen.”

Dr. Stein continued, “Our late-stage antifungal product candidate, rezafungin, continues to generate compelling data. We recently presented the full results from our pivotal ReSTORE Phase 3 clinical trial of rezafungin as a potential first-line treatment for candidemia and invasive candidiasis at the ECCMID 2022 meeting. This data, combined with the positive results from the previously completed STRIVE trial, will form the basis of a New Drug Application (NDA) filing with the U.S. Food and Drug Administration (FDA) and other regulators outside of the U.S., which we continue to anticipate submitting in mid-2022.”

Recent Corporate Highlights

• Announced completion of dosing in Phase 1 trial of CD388: In March 2022, Cidara announced that the first cohort of healthy volunteers completed dosing in its ongoing Phase 1 trial of CD388, a highly potent long-acting antiviral immunotherapy designed to deliver universal prevention of seasonal and pandemic influenza.
• Presented clinical results at ECCMID: In April 2022, Cidara presented new clinical data and analyses of rezafungin, a novel, once-weekly echinocandin in development for the treatment of candidemia and invasive candidiasis and prevention of invasive fungal infections, at the 32^nd European Congress of Clinical Microbiology and Infectious Diseases (ECCMID). The new data were presented in three presentations, including two late-breaking presentations highlighting full results from the global Phase 3 ReSTORE trial and the integrated analyses from the ReSTORE Phase 3 and STRIVE Phase 2 trials.
• Strengthened leadership team: During the second quarter, two prominent experts in oncology drug discovery and development were added to Cidara’s Scientific Advisory Board. Perry Nisen, M.D., Ph.D., chief executive officer of Quanta Therapeutics, and Ezra Cohen, M.D., FRCPSC, FASCO, Professor of Medicine, Division Chief Hematology/Oncology, Associate Director Moores Cancer Center, University of California, San Diego, both bring decades of experience to the Cidara team.

First Quarter 2022 Financial Results

• Revenue totaled $7.1 million for the three months ended March 31, 2022, compared with $2.4 million for the same period of 2021. The increase was primarily attributable to the revenue recognized in connection with Cidara’s collaboration with Janssen Pharmaceuticals.
• Cash, cash equivalents and restricted cash totaled $38.0 million as of March 31, 2022, compared with $62.3 million as of December 31, 2021.
• In March 2022, the Company achieved a $3.0 million milestone under the Janssen Collaboration Agreement tied to performance obligations identified in the original agreement. The Company received payment for this milestone in May 2022.
• Research and development expenses were $20.2 million for the three months ended March 31, 2022, compared to $15.8 million for the same period in 2021. The increase was primarily attributable to higher clinical expenses associated with the drug manufacturing costs for rezafungin, higher clinical expenses associated with the Janssen Collaboration Agreement, and higher consulting and personnel costs.
• General and administrative expenses were $5.2 million for the three months ended March 31, 2022, compared to $4.8 million for the same period in 2021. The increase was primarily attributable to higher consulting and legal costs, offset by a decrease in personnel costs.
• Net loss for the three months ended March 31, 2022 was $18.3 million, compared to a net loss of $18.3 million for the same period in 2021.
• As of March 31, 2022, Cidara had 69,049,247 shares of common stock outstanding, and 1,818,472 shares of Series X convertible preferred stock outstanding, which are convertible into 18,184,720 shares of common stock.
