About KO-947

KO-947 is a potent and selective small molecule ERK1/2 inhibitor. KO-947 exhibits potent anti-proliferative activity across a broad panel of tumor cell lines with mutations in BRAF, NRAS or KRAS and demonstrates prolonged pathway inhibition, both in vitro and in vivo. Durable tumor regression has been observed with KO-947 in preclinical cell line and patient derived xenograft models, including KRAS- and BRAF-mutant adenocarcinomas and squamous cell carcinomas lacking BRAF/RAS mutations.
