Complete Response on F2G Antifungal NDA

Share

FDA has issued F2G Ltd. a complete response letter on its NDA for olorofim, an antifungal for invasive fungal infections in patients who have limited or no treatment options. The letter requested additional data and analyses before it can approve the submission, according to the company. “The FDA encouraged the company to work with the agency to plan for the new analyses and develop the NDA package,” it says.

F2G says the original NDA contained data from the first 100 patients enrolled in the then-ongoing Phase 2b single-arm, open-label study (Study 32, NCT03583164). Since then, Study 32 has now completed enrollment with a total of 203 patients, and the full data set will now be submitted as part of the revised NDA package, it adds. “To expand on the studied patient population,” it continues, “F2G has initiated a global Phase 3 trial (OASIS) to compare treatment with olorofim versus AmBisome followed by standard of care in patients with proven or probable invasive fungal infection due to Aspergillus species (NCT05101187).”
