About BAY 86-9766

BAY 86-9766 (RDEA119) is a potent and highly selective inhibitor of mitogen-activated ERK kinase (MEK) for the treatment of cancer being developed under a global license agreement with Bayer Healthcare (Bayer). Preclinical and clinical data suggest that BAY 86-9766 has favorable properties, including once-daily oral dosing and excellent selectivity. In addition, BAY 86-9766 has been shown to suppress tumor cell growth in vitro and in vivo. Preclinical in vitro and in vivo oncology studies of BAY 86-9766 have demonstrated significant potential synergy across multiple tumor types when used in combination with other anti-cancer agents, including sorafenib (Nexavar®; Bayer, Onyx Pharmaceuticals, Inc.).
