J Clin Oncol:口服紫杉醇+Encequidar治疗转移性乳腺癌优胜静脉紫杉醇

2022-08-01 MedSci原创 MedSci原创

与静脉紫杉醇相比,口服紫杉醇+Encequidar提高了转移性乳腺癌患者的肿瘤缓解率,延长了PFS和OS

静脉紫杉醇 (IVpac) 因神经病变而复杂化,需要提前用药以预防超敏反应型反应。紫杉醇口服吸收不良;Encequidar (E) 是一种新型 P-糖蛋白泵抑制剂,可促进口服紫杉醇的吸收。

这是一项开放标签的III期临床试验,旨在比较转移性乳腺癌女性患者采用口服紫杉醇+E(oPac+E:紫杉醇 205 mg/m2,E 15 mg,每周连服3天)与IVpac(175 mg/m2,1次/3周)治疗的效果与安全性。

有合适的器官功能、且末次紫杉烷用药至少满1年的转移性乳腺癌女性患者被随机(2:1)分至oPac+E组或IVpac组。主要终点是确认的影像学缓解率。次要终点包括无进展生存期(PFS)和总生存期(OS)。


两组患者的PFS率和OS率

从拉丁美洲共招募了402位患者(oPac+E组 265位,IVpac组 137位)。oPac+E组和IVpac组的确认的缓解率分别是36%和23%(p=0.01)。oPac+E组和IVpac组的PFS分别是8.4个月和7.4个月(风险比[HR] 0.768,p=0.046),OS分别是22.7个月和16.5个月(HR 0.794,p=0.08)。

oPac+E组和IVpac组的3-4级不良反应发生率分别是55%和53%。与IVpac组相比,oPac+E组的神经病变和脱发的发生率更低,严重程度更轻,但恶心、呕吐、腹泻和中性粒细胞减少并发症更高,特别是在肝酶升高的患者中。oPac+E组和IVpac组分别有3%和0%的病例死亡是与治疗相关。

综上,与IVpac相比,oPac+E提高了转移性乳腺癌患者的肿瘤缓解率,延长了PFS和OS。oPac+E治疗的神经病变发生率更低、严重程度相对更轻;但中性粒细胞减少严重感染的发生率增加了。
