Blood Cancer J:奥比妥珠单抗+阿特珠单抗+来那度胺可有效治疗复发/难治性滤泡性淋巴瘤!

G-atezo-len方案对于复发性/难治性滤泡性淋巴瘤患者来说是一种有效的、耐受性良好的治疗方案

滤泡性淋巴瘤 (FL) 是最常见的一种惰性非霍奇金淋巴瘤 (NHL)。虽然绝大多数接受治疗的 FL 患者通常都能从初始化学免疫治疗中获得缓解,但是大部分患者最终会复发,并且对后续治疗的敏感性降低。这使我们迫切需要探索新的治疗方案,如PI3K抑制剂或其与抗CD-20单克隆抗体(mAb)和免疫调节剂的联合应用。

来那度胺是一种口服的活性免疫调节剂,具有直接抗肿瘤活性以及通过 T 细胞和自然杀伤 (NK) 细胞功能介导的间接作用。

近日,发表在“Blood Cancer Journal”上的一项研究开放标签、多中心的 Ib/II 期研究,评估了奥比妥珠单抗-阿特珠单抗-来那度胺 (G-atezo-len) 三联方案治疗复发/难治性 (R/R) 滤泡性淋巴瘤患者的疗效和安全性。

该试验初始阶段采用3+3剂量递增设计,旨在明确后续扩展阶段采用G-atezo-len诱导和维持治疗时来那度胺的推荐2期剂量。

无进展生存率

在最后的分析中,有38位患者(来那度胺:15 mg 4位、20 mg 34位)完成了试验。在诱导治疗结束时的完全缓解率为71.9%(在双重难治性患者[对利妥昔单抗和烷化剂]中完全缓解率为66.7%;在一线治疗后24个月内进展的患者中为50%)。36个月无进展生存率为68.4%。

32位患者的缓解持续时间

所有接受研究治疗的患者都至少发生了一次不良事件(AE;3-5级AE:32例[84%];重度AE:18例[47%];11位[29%]患者因AE导致研究治疗用药中断)。此外,还发生了两例致死性的AE(一例Merkel细胞癌,一例肉瘤样癌;两例都与研究用药无关)。

总而言之,G-atezo-len方案对于复发性/难治性滤泡性淋巴瘤患者来说是一种有效的、耐受性良好的治疗方案。该联合方案的不良反应与这三种药物单用时的一致,未出现新的安全性问题。
