Cidara Therapeutics Announces Two Presentations on Drug-Fc Conjugate, CD388, at IDWeek 2024
SAN DIEGO, Oct. 16, 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 upcoming presentations at IDWeek 2024, to be held October 16–19, 2024 in Los Angeles, CA. The presentations will highlight clinical data on the safety, pharmacokinetics, and prophylactic activity of Cidara’s clinical-stage influenza DFC asset, CD388.
“We are pleased to share these clinical results at this year’s IDWeek, which underscore the potential for CD388 as an effective and well-tolerated DFC for single-dose, season-long prevention of influenza,” said Jeffrey Stein, Ph.D., president and chief executive officer of Cidara. “We hope to share the results of our ongoing NAVIGATE Phase 2b clinical trial of CD388 at next year’s meeting.”
Oral Presentation
| Title: | CD388, a Novel Drug-Fc Conjugate (DFC), Demonstrates Prophylactic Activity in an Influenza Human Challenge Model |
| Presenter: | Taylor Sandison, MD, MPH, Cidara Therapeutics |
| Session: | Inhaling Insight: Advancements in Respiratory Viral Infections |
| Session Location: | 408A |
| Date/Time: | Saturday, October 19, 2:21–2:39 PM Pacific Time (PT) |
| Summary: | An analysis was conducted to determine prophylactic activity of CD388 against influenza disease in a Phase 2a human challenge study. The study found that a single subcutaneous dose of CD388 administered 5 days prior to influenza challenge was effective in preventing symptomatic disease among those who demonstrated seroconversion following influenza challenge. |
Poster and Rapid-Fire Presentation:
| Title: | Single-Dose and Repeat Single-Dose Ascending Dose Study Evaluating Safety, Tolerability, and Pharmacokinetics of Subcutaneous and Intramuscular CD388, a Novel Long-acting Drug-Fc Conjugate for Universal Prevention of Seasonal and Pandemic Influenza |
| Presenter: | Shawn Flanagan, Ph.D., Cidara Therapeutics |
| Session: | Novel Agents |
| Session Location: | Halls JK |
| Date/Time: | Friday, October 18, 2024, 12:15–1:30 PM (12:15 – 12:45 for rapid fire presentation) PT |
| Summary: | The safety, tolerability, and pharmacokinetics (PK) of CD388 were evaluated in healthy subjects administered either intramuscularly or subcutaneously with varying dosages of the drug. Absorption of CD388 was rapid both intramuscularly and subcutaneously, and elimination was slow, indicating that seasonal influenza prevention could be achieved with one dose per season. There was a lack of anti-drug antibody formation with repeat administration, supporting annual use of CD388, and no safety concerns were noted. |
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 initiation of a Phase 2b trial in September 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.
