• The FDA has granted priority review to vimseltinib for treating tenosynovial giant cell tumor (TGCT), setting a PDUFA goal date of February 17, 2025.
• Vimseltinib, a CSF1R inhibitor, demonstrated a 40% overall response rate in the MOTION phase 3 trial, significantly higher than placebo (0%).
• The MOTION trial also showed statistically significant improvements in active range of motion, physical function, and pain reduction with vimseltinib.
• Vimseltinib's manageable safety profile, without cholestatic hepatotoxicity or drug-induced liver injury, positions it as a potential new treatment option.
