It is now well established that ~40%C50% of all melanomas have a serineCthreonine protein kinase B-RAF (BRAF) mutation.1C3 The most commonly observed BRAF mutations are due to single nucleotide substitutions of glutamic acid. Over 90% are due to glutamic acid for valine (BRAFV600E).2 The second most common mutation is BRAFV600K, lysine for valine, representin?5%C6% of the mutations. Other rarely observed mutations include BRAFV600D, V600R, or even two-nucleotide variations.2,4 RAS mutations were also identified in melanoma cells. NRAS mutations are found in approximately 15% of all melanomas at diagnosis and in most cases are mutually exclusive with BRAF mutations.1,5,6 Both NRAS and BRAF mutations cause unchecked activation of the MAP kinase signal transduction pathway (RAS-RAF-MEK-ERK), leading to unregulated growth of tumor cells.1,5,7 Understanding of this pathway has led to the identification of specific targets for therapy. Development of BRAF inhibitors With the discovery of BRAF mutations in 2002,1 the first approved second-generation mutant BRAF-specific inhibitors were created using scaffold-based crystallography.8,9 This compound, vemurafenib (Zelboraf?, PLX4032; Plexxikon, Berkeley, CA, USA), was approved in 2011 for the treatment of BRAFV600E metastatic melanoma. The Phase III BRIM3 trial compared vemurafenib and dacarbazine (Table 1).10 The objective response rate for vemurafenib was 48% (95% CI: 42C55) compared to 5% (95% CI: 3C9) for dacarbazine ( em P /em 0.001).
