Cidara Therapeutics Announces First Subjects Dosed in Phase 2b NAVIGATE Trial Evaluating CD388 for the Prevention of Seasonal Influenza
The Phase 2b trial will enroll 5,000 subjects across clinical sites in the US and UK
SAN DIEGO, Sept. 23, 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 the first subjects dosed in the Phase 2b NAVIGATE trial to evaluate the efficacy and safety of CD388 for the pre-exposure prophylaxis of influenza during the current flu season.
The Phase 2b clinical trial is a randomized, double blind, controlled trial targeting 5,000 healthy unvaccinated adult subjects who are not at risk of complications from influenza. Three CD388 dose groups or placebo will be administered to subjects as a single dose at the beginning of the influenza season. Subjects will then be followed for the remainder of the influenza season to monitor for breakthrough cases. Rates of laboratory and clinically confirmed influenza will be compared between subjects receiving the various single doses of CD388 or placebo. The study will include sites in the US and UK.
“Effective new options are needed to prevent influenza, particularly for people who do not respond well to seasonal flu vaccines,” said Jeffrey Stein, Ph.D., president and chief executive officer of Cidara Therapeutics. “Since CD388 is not a vaccine, its activity does not rely upon an immune response and is thereby expected to work regardless of immune status. In addition, CD388 has demonstrated the potential to prevent infection by both seasonal and pandemic strains of influenza A and B. We are pleased to reach this important milestone, and look forward to monitoring the progress of the NAVIGATE study as this year’s flu season unfolds.”
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.
