A Phase 2 Study of Avutometinib (VS-6766) (Dual RAF/MEK Inhibitor) Alone and In Combination With Defactinib (FAK Inhibitor) in Recurrent Low-Grade Serous Ovarian Cancer (LGSOC)

This study will assess the safety and efficacy of avutometinib (VS-6766) monotherapy and in combination with defactinib in subjects with recurrent Low-Grade Serous Ovarian Cancer (LGSOC)

This is a multicenter, randomized, open-label Phase 2 study designed to evaluate safety and tolerability and preliminary efficacy of avutometinib (VS-6766) versus avutometinib (VS-6766) in combination with defactinib in subjects with molecularly profiled recurrent LGSOC.
