BMS-908662 (previously known as XL281) is a small molecule Raf kinase inhibitor that lies immediately downstream of RAS and are key components of the RAS/RAF/MEK/ERK kinase-signaling pathway. Bristol-Myers Squibb has received an exclusive worldwide license to develop and commercialize antineoplastic agent XL281. BMS-908662 participated in phase I development for the treatment of patients with melanoma and in combination with cetuximab for patients with colorectal cancer. However, further, development has been discontinued.
