Uses
1 INDICATIONS AND USAGE AVMAPKI FAKZYNJA CO-PACK is indicated for the treatment of adult patients with KRAS -mutated recurrent low-grade serous ovarian cancer (LGSOC) who have received prior systemic therapy. This indication is approved under accelerated approval based on tumor response rate and duration of response [see Clinical Studies (14) ]. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial. AVMAPKI FAKZYNJA CO-PACK, a combination of avutometinib and defactinib, each kinase inhibitors, is indicated for the treatment of adult patients with KRAS -mutated recurrent low-grade serous ovarian cancer (LGSOC) who have received prior systemic therapy.
Dosage
2 DOSAGE AND ADMINISTRATION AVMAPKI 3.2 mg administered orally twice weekly (Day 1 and Day 4) for the first 3 weeks of each 4-week cycle. ( 2.3 ) FAKZYNJA 200 mg administered orally twice daily for the first 3 weeks of each 4-week cycle. ( 2.3 ) 2.1 Patient Selection Select patients for the treatment of recurrent LGSOC with AVMAPKI FAKZYNJA CO-PACK based on the presence of a KRAS mutation in tumor specimens [see Clinical Studies (14) ] .

Pregnancy
8.1 Pregnancy Risk Summary Based on the mechanisms of action, AVMAPKI FAKZYNJA CO-PACK can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1) ] . There are no available data on the use of AVMAPKI FAKZYNJA CO-PACK in pregnant women to inform a drug-associated risk. Animal reproductive and developmental toxicity studies have not been conducted with avutometinib or defactinib; however, inhibition of either molecular pathway has been associated with embryo-fetal anomalies and lethality in animals.
