Array BioPharma announced results of a Phase 2 trial of selumetinib in women with recurrent low-grade serous ovarian or peritoneal cancer.
In the trial, 52 women each received 100mg doses of selumetinib orally twice daily in four-week cycles until disease progression or toxicity. The median number of cycles received was 4.5; 33% underwent ≥12 cycles. Prior to the trial, 58% of the patients in the trial had received three or more rounds of chemotherapy.
A disease control rate, defined as either complete or partial response or progression-free survival or progression-free survival of greater than 6 months, occurred in 81% of patients. Eight patients had complete (1) or partial (7) responses, and 34 (63%) had progression-free survival of >6 months. The median survival rate without cancer progression was 11 months.
Selumetinib is an anti-cancer drug in Phase 2 development in a range of tumors. It is a small molecule MEK inhibitor that targets a key position in the Ras-Raf-MEK-ERK signaling pathway. MEK has been shown to be frequently activated in cancer, in particular in tumors that have mutations in the RAS and RAF pathways.
