Class/mechanism: Tyrosine kinase inhibitor of some mutated forms of BRAF serine/threonine
kinase, including BRAF V600E. Also has been observed to inhibit other tyrosine kinases such as RAF1, ARAF, wild-type BRAF, SRMS, ACK1, MAP4K5, and FGR. Certain BRAF mutations, such as V600E, result in constitutive activation of cell proliferation pathways and tumor growth.
For conciseness and simplicity, HemOnc.org currently will focus on treatment regimens and not list information such as: renal/hepatic dose adjustments, metabolism (including CYP450), excretion, monitoring parameters (although this will be considered for checklists), or manufacturer. Instead, for the most current information, please refer to your preferred pharmacopeias such as Micromedex, Lexicomp, UpToDate (courtesy of Lexicomp), or the prescribing information.
