"Two Array BioPharma-invented MEK inhibitors, binimetinib (MEK162) and selumetinib, were showcased at the 50th annual meeting of the American Society of Clinical Oncology (ASCO). At the meeting, preliminary data for the combination of binimetinib and CDK4/6 inhibitor LEE011 (discovered by Novartis Institutes for BioMedical Research in collaboration with Astex Pharmaceuticals) from a Phase 1b/2 dose-escalation study conducted by Novartis in NRAS-mutant melanoma indicates the combination demonstrated an acceptable safety profile for most patients with promising preliminary antitumor activity. Additionally, preliminary data for selumetinib showed favorable clinical activity in pediatric patients with neurofibromatosis type 1 (NF1) and plexiform neurofibromas (PNs)."
Editor's note: This article discusses a melanoma treatment that combines two durgs: binimetinib (aka MEK162) and selumetinib. A clinical trial recently found that the combo shows promise for melanoma patients whose tumors have mutations in the NRAS gene, as detected by molecular testing. Binimetinib is also being tested as a potential treatment for patients whose tumors have mutations in the BRAF gene.
