纳武单抗联合替莫唑胺治疗在神经内分泌肿瘤患者中展现出了良好的活性

神经内分泌肿瘤(NEN)是一组异质性肿瘤,包括低级别胃肠胰神经内分泌肿瘤(GEP-NET)、胸腺和肺神经内分泌肿瘤以及侵袭性、快速生长的神经内分泌癌。转移性神经内分泌肿瘤患者的治疗方案有限。

本文报告了纳武单抗和替莫唑胺联合治疗晚期NEN患者的II期试验结果以及外周血免疫改变的结果。

这是一项非随机的2期临床试验,予以NEN患者纳武单抗和替莫唑胺联合治疗。主要终点是缓解率。次要终点包括无进展生存期(PFS)、总生存期(OS)和安全性。


无进展生存率

共招募了28位NEN患者,明确的缓解率为32.1%(9/28)。在11位肺NEN患者中,缓解率为64%(7/11);原发肿瘤部位不同的患者的缓解率有显著差异(肺 vs 其他;p=0.020)。中位PFS是8.8个月,中位OS是32.3个月。


总生存率

探索性血免疫细胞分析显示,在治疗2周后,循环CD8+ T细胞水平升高(27.9%±13.4% vs 31.7%±14.6%,p=0.03),CD4+ T细胞水平降低(59.6%±13.1% vs 56.5%±13.0%,p=0.001)。获得部分缓解的患者的表达LAG-3的总T细胞水平降低(0.18%±0.24% vs 0.83%±0.55%,p=0.028)。骨髓源性抑制细胞水平在研究期间升高,但与反应无关。

综上,纳武单抗联合替莫唑胺治疗在神经内分泌肿瘤患者中展现出了良好的活性,特别是在肺神经内分泌瘤患者中。
