Cidara Therapeutics to Participate in World Health Organization Meeting on H5N1 Influenza Preparedness and Response
SAN DIEGO, March 19, 2025 (GLOBE NEWSWIRE) -- Cidara Therapeutics, Inc. (Nasdaq: CDTX), a biotechnology company using its proprietary Cloudbreak® platform to develop drug-Fc conjugate (DFC) immunotherapies, today announced participation in the “Other pharmaceuticals as preventive tools” panel at a World Health Organization (WHO) global meeting on H5N1 influenza preparedness and response. The meeting, titled “What research is important to prepare and respond to H5N1 influenza outbreaks,” will be held virtually on March 19, 2025, from 1:00-7:15pm Central European Time (CET)/5:00-11:15am Pacific Time (PT), and the panel discussion will take place from 6:30-7:00 pm CET/10:30-11:00am PT.
“Global discussion forums are critical for the development of effective treatments to combat outbreaks of influenza, including the growing threat of H5N1,” said Les Tari, Ph.D., chief scientific officer of Cidara. “As the virus spreads, the need for robust strategies to prevent and respond to flu outbreaks is becoming increasingly critical. Our long-acting antiviral influenza preventative, CD388, currently in a 5,000 subject Phase 2b study, shows promise as a new modality that has demonstrated potent activity against all influenza A and B strains, including H5N1, in preclinical studies. I look forward to discussing the potential of CD388 with global leaders as a universal preventative of influenza outbreaks.”
H5N1 is one of several influenza viruses that causes a highly infectious respiratory disease in birds called avian influenza (or "bird flu "). Infections in mammals, including humans, have also been documented.
Meeting details:
Influenza H5 pathogens have been included in the list of priority pathogens by the WHO R&D Blueprint for Epidemics. To coordinate efforts for research preparedness of H5N1 outbreaks, this global consultation will review current and novel vaccines and preventive pharmaceuticals. The key objectives of this meeting are to identify knowledge gaps and priority research questions, outline regulatory pathways for mRNA vaccines and other novel approaches, and review other therapeutics, including monoclonal antibodies and long-acting antivirals.
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 announced completion of enrollment of its Phase 2b NAVIGATE trial in December 2024. Additional DFCs have been developed for oncology and in July 2024 Cidara received IND clearance for CBO421 which is intended to target CD73 in solid tumors. Cidara is headquartered in San Diego, California. For more information, please visit www.cidara.com.
