JCO:达拉菲尼联合曲美替尼治疗黑色素瘤效果显著

2014-11-18 MedSci译 MedSci原创

目的:临床前及早期的临床试验已经证实BRAF和MEK抑制剂联合治疗BRAF(V600)突变的黑色素瘤患者效果优于单药BRAF抑制剂。该研究评估了达拉菲尼和曲美替尼联合治疗既往接受过BRAF抑制剂的患者的安全性及疗效性。材料及方法:在这个开放性、I/II试验中,我们评估了达拉菲尼和曲美替尼的药理机制、安全性及疗效。该试验报道了联合治疗的结果,包括26例既往接受BRAF抑制剂进展的患者(B组)以及45

目的:


临床前及早期的临床试验已经证实BRAF和MEK抑制剂联合治疗BRAF(V600)突变的黑色素瘤患者效果优于单药BRAF抑制剂。该研究评估了达拉菲尼和曲美替尼联合治疗既往接受过BRAF抑制剂的患者的安全性及疗效性。

材料及方法:

在这个开放性、I/II试验中,我们评估了达拉菲尼和曲美替尼的药理机制、安全性及疗效。该试验报道了联合治疗的结果,包括26例既往接受BRAF抑制剂进展的患者(B组)以及45例达拉菲尼单药治疗进展后交叉治疗的患者。

结果:

B组和C组的ORR分别为15% (95% CI, 4%-35%)及13% (95% CI, 5%-27%);另外,两组中分别有50%及44%的患者病情稳定超过8周。C组中,中位PFS为3.6个月(95% CI, 2- 4),中位OS为11.8个月(95% CI, 8-25)。对于既往接受达拉菲尼治疗超过6个月及不足6个月的患者而言,联合治疗在超过6个月的患者中表现出相对较好的疗效;两组的中位PFS分别为3.9 个月(95% CI, 3- 7),1.8个月 (95% CI, 2-4; HR:0.49; P = 0.02), ORR分别为26% (95% CI, 10%-48%) 及0% (95% CI, 0%-15%)。

结论:

达拉菲尼和曲美替尼联合治疗对于BRAF抑制剂耐药的黑色素瘤患者表现出一定的临床获益。对于既往接受BRAF抑制剂单药治疗获益超过6个月,快速进展后继续使用BRAF抑制剂获益微小的患者,可选择该方案作为后续治疗策略。
