BRAF mutations are found in ~50% of metastatic melanomas, most commonly in codon V600. Vemurafenib improves progression-free survival and overall survival in patients with advanced BRAF-mutated melanoma. The results of a descriptive study evaluating vemurafenib in patients with advanced melanoma harbouring BRAF mutations other than V600E are reported. Eligible patients with stage IIIC or IV melanoma and non-V600E BRAF mutations received vemurafenib (960 mg, twice daily). End points included investigator-assessed best overall response rate (primary), time to response, duration of response, progression-free survival, overall survival and safety. Planned (V600K vs. non-V600K mutations) subgroup analyses were carried out. Thirty-one patients were enrolled; 13 (42%) had V600K mutations and 18 (58%) had other mutations. Investigator-assessed confirmed that the best overall response rate was 23% (95% confidence interval=10-41%) in the overall population, and was similar between patients with V600K mutations (23%; 95% confidence interval=5-54%) versus other mutations (22%; 95% confidence interval=6-48%). Responses were observed in patients with V600K (n=3), V600E2 (n=1), V600R (n=1), L597S (n=1) and D594G (n=1) mutations. No new safety signals were reported. Vemurafenib showed activity in patients with advanced melanoma with rarer BRAF mutations.
约50%的转移性黑色素瘤中存在BRAF突变，最常见于密码子V600。维莫非尼可改善晚期BRAF突变型黑色素瘤患者的无进展生存期和总生存期。本文报告了一项描述性研究的结果，该研究评估了维莫非尼在携带非V600E BRAF突变的晚期黑色素瘤患者中的疗效。符合条件的IIIC期或IV期黑色素瘤且有非V600E BRAF突变的患者接受维莫非尼治疗（960毫克，每日两次）。终点指标包括研究者评估的最佳总体缓解率（主要指标）、缓解时间、缓解持续时间、无进展生存期、总生存期和安全性。进行了计划中的亚组分析（V600K与非V600K突变）。共纳入31例患者；13例（42%）有V600K突变，18例（58%）有其他突变。研究者评估确认，总体人群的最佳总体缓解率为23%（95%置信区间=10-41%），V600K突变患者（23%；95%置信区间=5-54%）与其他突变患者（22%；95%置信区间=6-48%）的缓解率相似。在有V600K（n=3）、V600E2（n=1）、V600R（n=1）、L597S（n=1）和D594G（n=1）突变的患者中观察到缓解。未报告新的安全信号。维莫非尼在携带罕见BRAF突变的晚期黑色素瘤患者中显示出活性。
