目的: 对曲美替尼治疗转移性黑色素瘤在药理学、药代动力学、临床疗效、安全性、临床管理、成本等方面进行了总结。 摘要:约40-60%的恶性黑素瘤有BRAF600基因密码子的突变基因,其导致蛋白激酶(MAPK)通道的激活。曲美替尼是首个细胞外信号的MEK抑制剂,靶标是在对肿瘤细胞增殖,存活,入侵,肿瘤血管生成,逃避凋亡中起关键作用的MEK激酶。美国食品药品监督管理局批准曲美替尼用于BRAF基因V60

目的: 对曲美替尼治疗转移性黑色素瘤在药理学、药代动力学、临床疗效、安全性、临床管理、成本等方面进行了总结。

摘要:约40-60%的恶性黑素瘤有BRAF600基因密码子的突变基因,其导致蛋白激酶(MAPK)通道的激活。曲美替尼是首个细胞外信号的MEK抑制剂,靶标是在对肿瘤细胞增殖,存活,入侵,肿瘤血管生成,逃避凋亡中起关键作用的MEK激酶。美国食品药品监督管理局批准曲美替尼用于BRAF基因V600E或V600K突变的肿瘤患者的治疗。此外, 曲美替尼也可与达拉菲尼(BRAF抑制剂)联合使用。曲美替尼不适用于之前由于不良反应和可能的交叉抗药性而进行BRAF抑制剂治疗的病人。最常见的不良反应与曲美替尼单药治疗和联合治疗相关,不良反应为皮疹、腹泻、外周水肿、疲劳和皮炎。曲美替尼单药治疗的推荐剂量是2毫克,每日口服一次,直到疾病进展或出现不可接受的毒性。2毫克的剂量,大约30天的疗程将花费大约9135美元。

结论: 曲美替尼,新型的MEK抑制剂,为BRAF V600E/K转移性黑色素瘤的患者提供了对之前存在的BRAF抑制剂单个或联合治疗无治疗效果的一种替代疗法。更多的研究需要用来确定曲美替尼的安全有效的组合或与其他疗法相比对曲美替尼进行排序。

NEJM: Dabrafenib与Trametinib联用提高黑色素瘤患者的总生存率

研究背景: 促分裂素原活化蛋白激酶 (MAPK) 信号转导通路是细胞内最重要的信号通路之一, 该通路通过RAS、RAF、有丝分裂原活化蛋白激酶 (MEK) 及胞外信号调节激酶 (ERK) 的特异性级联磷酸化将信号由细胞外传入细胞核内。BRAF是RAF三个亚型之一,是MAPK通路重要的转导因子。在催化底物方面, BRAF以MEK1/2为底物,是MEK最主要的活化激酶。 BRAF在3个亚型
