Cidara Therapeutics Provides Corporate Update and Reports Fourth Quarter and Full Year 2021 Financial Results

SAN DIEGO, March 07, 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 three months and full year ended December 31, 2021 and provided an update on its corporate activities and product pipeline.

“We made significant progress on several key initiatives during the fourth quarter,” said Jeffrey Stein, Ph.D., president and chief executive officer of Cidara. “Of particular note is our December 2021 announcement of positive topline results from our pivotal ReSTORE Phase 3 clinical trial of rezafungin as a potential first-line treatment for candidemia and invasive candidiasis, which, combined with the data from the previously completed STRIVE trial, we expect 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. in mid-2022.”

Dr. Stein continued, “In addition, we announced in February 2022 that the FDA had accepted Cidara’s Investigational New Drug Application (IND) for our lead influenza drug-FC conjugate (DFC), CD388. This represents a significant milestone for our Cloudbreak program, which we anticipate will allow us to advance CD388 into the clinic this quarter.”

Recent Corporate Highlights

• Announced FDA acceptance of IND for CD388: In February 2022, Cidara announced that the FDA has accepted Cidara’s IND for its lead flu DFC, CD388, which is being developed in collaboration with Janssen. Cidara intends to initiate a Phase 1 study in healthy volunteers before the end of the current quarter. Janssen will fund the Phase 1 trial-related development costs and all future research, development, manufacturing and commercialization for CD388. Later this year, Cidara expects the availability of new preclinical data for other antiviral DFCs, including RSV and SARS, as well as preclinical data for its oncology DFCs directed against solid tumors.
• Announced positive topline results for rezafungin: In December 2021, Cidara and Mundipharma announced positive topline data from the pivotal ReSTORE Phase 3 clinical trial evaluating the efficacy and safety of its once-weekly antifungal candidate rezafungin as a potential first-line treatment for candidemia and invasive candidiasis. Rezafungin met the primary endpoint for the FDA 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) of submission of global cure at Day 14. Both results demonstrated statistical non-inferiority of rezafungin dosed once-weekly, versus caspofungin dosed once-daily, the current standard of care. Rezafungin was generally well tolerated and had a similar safety profile to caspofungin.

  Based on the positive topline results of the ReSTORE trial, Cidara intends to file an NDA for rezafungin for the treatment of candidemia and/or invasive candidiasis with the FDA, and similar applications with other regulators outside the U.S., in mid-2022.

  In addition, integrated results from both the Phase 3 ReSTORE trial and the Phase 2 STRIVE trial across all patients who received the 400mg / 200mg dosing regimen showed improved outcomes as compared to caspofungin across several key measures:

  – All-cause mortality at Day 30, the primary endpoint for the FDA, was 18.7% for rezafungin and 19.4% for caspofungin.

  – Mycological eradication at Day 5 and Day 14 was 73.4% and 71.9%, respectively, for rezafungin and 64.5% and 68.4%, respectively, for caspofungin.

  – Mycological eradication at Day 5 for patients with candidemia only was 80.0% for rezafungin and 67.8% for caspofungin.

  – Patients receiving rezafungin had faster median time to negative blood culture (22.3 days) compared to caspofungin (26.3 days).

• Held pre-NDA discussions with the FDA: Following recent positive pre-NDA discussions with the FDA about Cidara’s clinical and nonclinical data package, Cidara remains on track to file its NDA for rezafungin for the treatment of candidemia and/or candidiasis in mid-2022.
• Announced granting of Promising Innovation Medicine designation for rezafungin: In March 2022, Cidara and Mundipharma announced that the Medicines and Healthcare Products Regulatory Agency (MHRA) in the UK has granted rezafungin the Promising Innovative Medicine (PIM) designation for the treatment of invasive candidiasis, which permits the use of medicines not yet approved by the relevant regulatory authorities.
• Named San Diego Metro Area Top Workplace: In November 2021, Cidara was named a Top Workplace by The San Diego Union-Tribune for the fifth consecutive year, ranking among the top 100 companies.
• Raised $38.5 million in equity sales: In October 2021, Cidara sold and issued 17,064,511 shares of its common stock and 744,194 shares of its Series X Convertible Preferred stock in two concurrent but separate underwritten public offerings. The gross proceeds to Cidara from these offerings, before deducting underwriting discounts and commissions and estimated offering expenses, were approximately $38.5 million.

Fourth Quarter and Full Year 2021 Financial Results

• Revenue totaled $7.2 million and $49.6 million for the three months and full year ended December 31, 2021, respectively, compared with $3.7 million and $12.1 million for the same periods in 2020.
• Cash, cash equivalents and restricted cash totaled $62.3 million as of December 31, 2021, compared with $42.9 million as of December 31, 2020.
• As of December 31, 2021, Cidara had 67,863,674 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.
• Research and development expenses were $19.0 million and $73.1 million for the three months and full year ended December 31, 2021, respectively, compared to $21.1 million and $68.0 million for the same periods in 2020. The increase in research and development expenses for the full year ended December 31, 2021 compared to the full year ended December 31, 2020 is primarily due to increased expense associated with Cidara’s Cloudbreak platform and higher personnel costs.
• General and administrative expenses were $5.0 million and $18.7 million for the three months and full year ended December 31, 2021, respectively, compared to $4.1 million and $15.9 million for the same periods in 2020. The increase in general and administrative expenses is primarily due to higher consulting, legal, and personnel costs.
• Net loss for the three months ended December 31, 2021 was $16.8 million, compared to a net loss of $21.6 million for the fourth quarter of 2020. Net loss for the full year ended December 31, 2021 was $42.5 million, compared to a net loss of $72.1 million for the year ended December 31, 2020.
