Cidara Therapeutics Announces BARDA Award to Support Expanded Manufacturing and Clinical Development of CD388, its Non-Vaccine Influenza Preventative Therapeutic

SAN DIEGO, Oct. 02, 2025 (GLOBE NEWSWIRE) -- Cidara Therapeutics, Inc. (NASDAQ:CDTX), a biotechnology company using its proprietary Cloudbreak^® platform to develop drug-Fc conjugate (DFC) therapeutics, today announced it has received an award valued up to $339M from the Biomedical Advanced Research and Development Authority (BARDA), part of the Administration for Strategic Preparedness and Response (ASPR) within the U.S. Department of Health and Human Services (HHS).

The multi-year agreement consists of a Base contract with Option periods. The Base period funding of $58M over 24 months supports the onshoring of CD388 manufacturing to the United States as an addition to the initial commercial supply chain. This initial funding will also be used to conduct a clinical trial to demonstrate the comparability of a higher-concentration formulation and different presentations of CD388, further characterize its activity against pandemic influenza strains in non-clinical models and initiate the development of clinical trial protocols for expanded populations. The Option periods funding up to $281M, if requested by Cidara and exercised by the U.S. government, would support additional clinical and non-clinical studies of CD388 in specific populations, as a complement to the company's plans for potential Biologics License Application (BLA) submission to the U.S. Food and Drug Administration (FDA).

"Clinical and non-clinical data generated to date suggest that CD388 has the potential to be an effective non-vaccine preventative for both pandemic and seasonal influenza," said Jeffrey Stein, Ph.D., president and chief executive officer of Cidara. "A long-acting, universal influenza preventative that confers broad protection against all strains of influenza across all populations is critical for pandemic preparedness, especially for the millions of Americans who are immune-compromised, have comorbidities that can lead to severe complications from influenza infection, or the elderly who have diminished response to vaccines. We welcome BARDA's partnership that will enable us to accelerate domestic supply options for CD388 production. This will both expand our commercial supply capacity, as well as ensure U.S. supply of CD388 in the event of an influenza pandemic."

This project is being supported in whole or in part with federal funds from the U.S. Department of Health and Human Services; Administration for Strategic Preparedness and Response; Biomedical Advanced Research and Development Authority (BARDA), under contract number 75A50125C00017.

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 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.
