Biafungin (formerly SP 3025 or CD101), a highly stable echinocandin and an antifungal drug that was studied against panels of Candida and Aspergillus clinical isolates. Biafungin was involved in phase II clinical trials in the treatment of acute moderate to severe vulvovaginal candidiasis. Seachaid Pharmaceuticals invented this drug. Then Cidara Therapeutics acquired a worldwide exclusive license to develop and commercialize the drug.
