About Cidara Therapeutics

Cidara Therapeutics is using its proprietary Cloudbreak^® platform to develop novel drug-Fc conjugates (DFCs). These targeted immunotherapies offer the unique opportunity to create “single molecule cocktails” comprised of targeted small molecules and peptides coupled to a human antibody fragment (Fc). DFCs are designed to save lives and improve the standard of care for patients facing cancers and other serious diseases by inhibiting specific disease targets while simultaneously engaging the immune system. In addition, Cidara received FDA approval for REZZAYO™ (rezafungin for injection), which it has licensed to multiple partners to commercialize in the U.S. and ex-U.S. Cidara is headquartered in San Diego, California.
