Phase 3

Recruiting

• Conditions: Low Grade Serous Ovarian Cancer
• Interventions: Drug: avutometinib; Drug: Pegylated liposomal doxorubicin; Drug: Defactinib; Drug: Paclitaxel; Drug: Letrozole; Drug: Anastrozole

• Registration Number: NCT06072781
• Lead Sponsor: Verastem, Inc.

Brief Summary

This study will assess the safety and efficacy of avutometinib (VS-6766) in combination with defactinib versus Investigator's choice of treatments (ICT) in subjects with recurrent LGSOC who have progressed on a prior platinum-based therapy.

Detailed Description

This international, randomized, open-label, Phase 3 study will compare the investigational combination of avutometinib plus defactinib versus Investigator's Choice of Treatments (ICT) in patients with recurrent LGSOC who have progressed on a prior platinum-based therapy. Avutometinib and defactinib are both types of drugs called kinase inhibitors. Kinase inh...
