SCYNEXIS completed its Phase 1 SAD/MAD study of intravenous SCY-247, reporting the drug was generally well tolerated with no drug-related serious adverse events across 56 healthy participants. Once-daily IV doses of 50 mg or higher achieved exposures at or above the efficacy target identified in murine models of invasive candidiasis, and the company plans to initiate Phase 2 in oral and IV formulations in 2027, subject to FDA agreement.
