Item 8.01 Other Events.

Following a recent review by GSK of the manufacturing process and equipment at the vendor that manufactures the ibrexafungerp drug substance, SCYNEXIS became aware that a non-antibacterial beta-lactam drug substance is manufactured using equipment common to the manufacturing process for ibrexafungerp. Current FDA guidance recommends segregating the manufacture of beta-lactam compounds from other compounds since beta-lactam compounds have the potential to act as sensitizing agents that may trigger hypersensitivity or an allergic reaction in some people. In the absence of the recommended segregation, there is a risk of cross contamination. It is not known whether any ibrexafungerp has been contaminated with a beta-lactam compound and SCYNEXIS has not received reports of adverse events established to be due to the possible beta-lactam cross contamination. Nonetheless, in light of this risk and out of an abundance of caution (and aligned with GSK’s recommendation), SCYNEXIS is recalling BREXAFEMME® (ibrexafungerp tablets) from the market and placing a temporary hold on clinical studies of ibrexafungerp, including the Phase 3 MARIO study, until a mitigation strategy and a resupply plan are determined.
