Fosravuconazole (trade name Nailin) is a triazole antifungal agent.[1][2] In Japan, it is approved for the treatment of onychomycosis, a fungal infection of the nail.[3] It is a prodrug that is converted into ravuconazole.[1]

Drugs for Neglected Diseases Initiative (DNDi) and the Japanese pharmaceutical company Eisai found that fosravuconazole works as a treatment for mycetoma, a serious condition.[1][4][5] The Phase II clinical trial found that oral fosravuconazole was safe, patient-friendly, and effective in treating eumycetoma.[6][7] Eumycetoma mainly affects young adults in poorer, rural areas; the standard treatment is itraconazole, which is much more expensive at about US$2,000 for a year than fosravuconazole and unaffordable, and not available in all endemic countries.[7]
