WebDec 13, 2024 · Class II BRAF mutations, the topic of this article, have been the subject of several tantalizing clinical case reports in patients with melanoma. In these studies, in one case supported by in vitro confirmation, individual examples of remarkable efficacy were demonstrated by MEKi, inducing deep and durable responses ().Several studies are … WebJul 10, 2024 · Among class II BRAF mutations, those affecting the K601 codon targets the activation segment of BRAF adjacent to the V600 position and this results in an increased activation of the MAPK pathway (3, 14). Among K601 variants, K601E occurs in about one percent of melanomas, resulting in a single amino acid substitution of lysine by glutamic …
WebAug 28, 2024 · For class II or III mutations, including BRAF-fusions, preclinical data and data in other cancers clearly support the inefficacy of type I RAF inhibitors. In tumors with these mutations, novel RAF inhibitors that prevent paradoxical activation, those that disrupt BRAF dimerization, or small molecule inhibitors targeting MEK or ERK may have ...
