Our Pipeline

Our lead compound, SF001, was designed to bind specifically to fungal ergosterol, thereby mitigating the toxicities associated with binding to mammalian cholesterol. SF001 is currently in Phase 1 clinical studies.


Our seasoned leadership team brings more than 200 years of collective expertise in antifungal drug development. The team is led by cofounder Kieren Marr, MD, MBA, FIDSA, and backed by Deerfield Management Company—an investment firm dedicated to advancing healthcare through information, investment, and philanthropy.
