    Binimetinib (MEK162; ARRY-438162) is a potent, adenosine triphosphate-uncompetitive, highly selective allosteric inhibitor of MEK1/2 with demonstrated on-target activity in vitro and in vivo, including models of cancer [...] In vivo, binimetinib displays broad anti-tumour activity in xenograft models derived from melanoma, colorectal cancer, non-small cell lung cancer (NSCLC), fibrosarcoma, cholangiocarcinoma, and pancreatic cancer. These non-clinical data support the use of binimetinib in a wide variety of tumour types, with a priority in tumours with aberrantly activated MAPK pathway signalling.

    Binimetinib is an oral reversible inhibitor of mitogen-activated extracellular signal-regulated kinase (MEK) 1/2. [...] Binimetinib inhibits MEK 1/2 downstream from BRAF and halts cancer cell signaling and survival. [...] Binimetinib is approved in combination with encorafenib, a BRAF inhibitor, for the treatment of unresectable or metastatic melanoma with a BRAF V600E/K mutation, as detected by an FDA-approved test.
