Avutometinib and defactinib: a novel dual pathway inhibition strategy for recurrent KRAS-mutant low-grade serous ovarian cancer

The combination of avutometinib (a RAF/MEK inhibitor) and defactinib (a FAK inhibitor) demonstrated meaningful efficacy and tolerability in recurrent KRAS-mutated low-grade serous ovarian carcinoma, as evidenced by clinically meaningful response rates and manageable adverse events.Avutometinib plus defactinib is a new, individualized treatment option for recurrent KRAS-mutated low-grade serous ovarian carcinoma.The evidence supporting these agents highlights their potential to address the unique therapeutic needs of this patient population, offering an option tailored to molecular characteristics and disease recurrence.Avutometinib plus defactinib represents a significant advancement in the management of recurrent KRAS-mutated low-grade serous ovarian carcinoma, leading to US Food and Drug Administration accelerated approval and inclusion in the National Comprehensive CancerNetwork guidelines as a Category 2A recommendation for this patient population.This literature review summarizes the pharmacology of avutometinib and defactinib and the clinical trial data supporting the combination's approval.The authors discuss adverse event management and the implications for integration into routine clinical practice.Clinicians caring J o u r n a l P r e -p r o o f for patients with low-grade serous ovarian carcinoma can use the drug knowledge and evidence 21 outlined in this review to assist with implementing avutometinib and defactinib therapy.
