Description: Refametinib, also known as RDEA119, BAY 86-9766, is an orally bioavailable selective MEK inhibitor with potential antineoplastic activity. MEK inhibitor RDEA119 specifically inhibits mitogen-activated protein kinase kinase 1 (MAP2K1 or MAPK/ERK kinase 1), resulting in inhibition of growth factor-mediated cell signaling and tumor cell proliferation. MEK, a dual specificity threonine/tyrosine kinase, is a key component of the RAS/RAF/MEK/ERK signaling pathway that regulates cell growth; constitutive activation of this pathway has been implicated in many cancers.

BAY 86-9766, formerly known as RDEA119, is currently being developed by Ardea. BAY 86-9766 is a potent, non-ATP competitive, highly-selective inhibitor of MEK. According to Ardea Inc's website, preclinical and clinical data suggest that BAY 86-9766 has favorable properties, including once-daily, oral dosing, excellent selectivity and limited retention in the brain, which may result in a reduced risk of central nervous system (CNS) side effects at doses expected to be effective, a problem associated with other members of this class of compounds. In addition, BAY 86-9766 has been shown to suppress tumor cell growth in-vitro and in-vivo. Phase 1 data have demonstrated that BAY 86-9766 has a long half-life and favorable pharmacokinetic properties, allowing for once-daily oral dosing. Preclinical in vitro and in vivo oncology studies have demonstrated significant potential synergy across multiple tumor types when BAY 86-9766 is used in combination with other approved anti-cancer therapeutics, including sorafenib (NexavarÂ®; Bayer HealthCare, Onyx Pharmaceuticals).
