The FDA recently approved a new therapy, Avmapki Fakzynja Co-Pack (avutometinib capsules; defactinib tablets) from Verastem Oncology, indicated for the treatment of adult patients with KRAS-mutated recurrent low-grade serous ovarian cancer (LGSOC) who have received prior systemic therapy. The therapy, a combination of avutometinib and defactinib, each kinase inhibitors, is co-packaged for oral use.
Dosing presents a challenge for patients as one drug is administered twice weekly while the companion drug is dosed twice daily for three weeks then followed by a one-week therapy hold for each therapy.
Low-grade serous ovarian cancer (LGSOC) is a rare, persistent subtype of ovarian cancer that differs markedly from high-grade serous ovarian cancer (HGSOC) in both biological characteristics and therapeutic response. LGSOC demonstrates lower sensitivity to chemotherapy, exhibits a high recurrence rate, and frequently necessitates specialized treatment strategies. This malignancy predominantly affects younger women, with diagnoses most commonly occurring between ages 20–30 and 50–60, and the median survival is approximately ten years. It is estimated that 6,000–8,000 women in the United States are currently living with LGSOC. Most cases are associated with mutations in the RAS signaling pathway, and approximately 30% present with a specific KRAS mutation.
The company announced that it will charge $48,500 for a 28-day regimen of the treatment, which includes two 3.2 mg doses per week of Avmapki and two daily 200 mg doses of Fakzynja.
Also, the company has selected Onco360 to distribute the therapy.
