Avutometinib (CH5126766) (potassium) is a RAF/MEK clamp that potently inhibits RAF/MEK kinase activity and induces dominant negative RAF-MEK complexes preventing phosphorylation of MEK by ARAF, BRAF and CRAF. Avutometinib (potassium) shows anti-proliferative potency across tumor cell lines carrying KRAS mutations including PDAC cell lines. Avutometinib (potassium) induces tumor inhibition and increases survival in a KRAS/p53 pancreatic cancer mouse model. Avutometinib (potassium) is promising for research of low-grade-serous-ovarian-carcinoma (LGSOC), ovarian cancer and pancreatic ductal adenocarcinoma (PDAC)[1][2].
