Cidara Therapeutics Announces Two Presentations on Innovative Drug-Fc Conjugate, CD388, at the 2024 OPTIONS XII for the Control of Influenza Conference

SAN DIEGO, Sept. 25, 2024 (GLOBE NEWSWIRE) — Cidara Therapeutics, Inc. (Nasdaq: CDTX), a biotechnology company using its proprietary Cloudbreak^® platform to develop drug-Fc conjugate (DFC) immunotherapies designed to save lives and improve the standard of care for patients facing serious diseases, today announced two presentations at OPTIONS XII for the Control of Influenza conference, to be held September 29 through October 2, 2024 in Brisbane, Australia. The presentations, one oral and one poster, will highlight safety and pharmacokinetic (PK) data from clinical studies of CD388, Cidara’s influenza drug-Fc conjugate (DFC) candidate.

“We are pleased to have the opportunity to present at this year’s OPTIONS XII conference and share the clinical data on our universally active influenza preventative, CD388,” said Jeffrey Stein, Ph.D., president and chief executive officer of Cidara. “These data support the safety of CD388 administered over a range of doses via multiple routes of administration. Moreover, the pharmacokinetic data support the potential use of CD388 in immune compromised as well as immune competent populations to provide season-long protection against influenza A and B.”

Oral Presentation
Title: Safety Data from Phase 1 and Phase 2a Studies of CD388, a Drug Fc-conjugate for Seasonal Pan-Influenza Prophylaxis
Presenter: Taylor Sandison, MD, MPH, Chief Medical Officer, Cidara Therapeutics
Date/Time: Tuesday, October 1, 2024, 15:51–16:04 AEST

This presentation summarizes the safety data from three CD388 clinical trials that involved 108 subjects who were followed for approximately 5–14 months. There were no dose-, route- or repeat-dose-related treatment-emergent adverse events (TEAEs). Overall, CD388 administered via subcutaneous or intramuscular injection was safe and well-tolerated in all three clinical trials. These data support further clinical studies with CD388 for single-dose prevention of seasonal influenza.

Poster Presentation
Title: Pharmacokinetics and Safety of CD388 Following Subcutaneous Administration in Healthy Japanese Participants
Presenter: Taylor Sandison, MD, MPH, Chief Medical Officer, Cidara Therapeutics
Date/Time: Sunday, September 29, 18:30-20:30 AEST

This presentation summarizes the pharmacokinetics (PK) and safety data of 27 healthy volunteers of Japanese descent dosed subcutaneously with a single dose of CD388 (50, 150, or 450 mg) or placebo. Overall PK parameters showed low-to-moderate variability across all doses and were similar to results from a previous Phase 1 clinical study in Western participants. Safety observations were comparable across the study arms. There were no clinically significant treatment-emergent adverse events (TEAE). These data support further clinical studies with CD388 in the Japanese population for prevention of seasonal influenza.

About CD388
CD388 is an investigational drug-Fc conjugate (DFC) comprised of multiple copies of a potent small molecule neuraminidase inhibitor stably conjugated to a proprietary Fc fragment of a human antibody. DFCs are not vaccines or monoclonal antibodies but are low molecular weight biologics which are designed to function as long-acting small molecule inhibitors. CD388 was designed to provide universal protection against all known strains of seasonal and pandemic influenza with the potential to provide season-long protection with a single subcutaneous or intramuscular administration. Importantly, because CD388 is not a vaccine, its activity is not reliant on an immune response and thereby is expected to be efficacious in individuals regardless of immune status.

About Cidara Therapeutics
Cidara Therapeutics is using its proprietary Cloudbreak^® platform to develop novel drug-Fc conjugates (DFCs) comprising targeted small molecules or peptides coupled to a proprietary human antibody fragment (Fc). Cidara’s lead DFC candidate, CD388, is a long-acting antiviral designed to achieve universal prevention of seasonal and pandemic influenza with a single dose by directly inhibiting viral proliferation. In June 2023, CD388 was granted Fast Track Designation by the U.S. Food and Drug Administration (FDA), and the Company plans to advance CD388 into a Phase 2b trial in the 2024 Northern Hemisphere influenza season. Additional DFCs have been developed for oncology and in July 2024 Cidara received IND clearance for CBO421 which will be developed to target CD73 in solid tumors. Cidara is headquartered in San Diego, California. For more information, please visit www.cidara.com.
