JTO:Rova-T联合纳武单抗或伊匹单抗治疗广泛期小细胞肺癌的疗效和安全性

2021-03-04 MedSci原创 MedSci原创

本研究旨在评估Rova-T联合纳武单抗或伊匹单抗用于既往治疗过的广泛期小细胞肺癌(ES SCLC)的安全性和有效性。

δ样蛋白3(DLL3)是一种在初始肿瘤细胞中表达的新型靶标蛋白,80%以上的小细胞肺癌患者会表达该蛋白。Rovalpituzumab tesirine(Rova-T)是一种靶向DLL3的抗体-药物耦合物。

本研究是一项开放的I/II期研究,旨在评估Rova-T联合纳武单抗或伊匹单抗用于既往治疗过的广泛期小细胞肺癌(ES SCLC)的安全性和有效性。

将经组织学/细胞学确诊的、既往治疗过(≥2个治疗方案)的ES SCLC患者分为两组。纳武单抗组接受0.3 mg/kg Rova-T(每6周1次,共2个疗程)+360 mg 纳武单抗(从第4周开始,2个3周疗程)。伊匹单抗组接受与纳武单抗组相同剂量的Rova-T+1 mg/kg 伊匹单抗(4个3周疗程)和1 mg/kg 伊匹单抗(第4周开始)。从第10周开始,两组患者每4周接受一次480 mg的纳武单抗治疗,主要目标是评估安全性/耐受性和有效性。

两组的治疗时间和缓解持续时间

42名患者接受了治疗:纳武单抗组 30人、伊匹单抗组 12人。总体而言,43%的患者既往接受过两种或两种以上的治疗。所有患者都经历了一次或多次需紧急治疗的不良事件(TEAE);41名患者报告了被研究者认为与研究药物有关的紧急不良事件

最常见的TEAE为胸腔积液(n=20,48%),最常见的3级及以上的TEAE为贫血(n=9,21%)。此外,纳武单抗组还报告了3例与研究药物有关的5级TEAE:肺炎(n=2)和急性肾损伤(n=1)。

两组靶病灶的最佳百分比变化

客观有效率为30%(12/40),其中纳武单抗组为27.6%(8/29),伊匹单抗组为36.4%(4/11),均为部分缓解。

疗效总结

综上,虽然Rova-T和纳武单抗或伊匹单抗的联合方案用于既往治疗过的ES SCLC患者中可获得良好的抗肿瘤活性,但患者对该研究评估的剂量水平和给药方案不能很好地耐受

Lancet Oncol:伊匹单抗联合纳武单抗治疗III期黑色素瘤的更佳剂量方案

III期黑色素瘤患者的预后极差。在两个独立的小型早期试验中,伊匹单抗联合纳武单抗(标准剂量)可诱导较高比例的患者获得病理缓解,而且在中位随访32个月内,病理缓解的患者无一复发。但标准剂量的伊匹单抗联合纳武单抗的毒性较强,限制了该疗法的广泛临床应用。研究人员开展2期随机对照试验(OpACIN-neo)探究伊匹单抗联合纳武单抗的合适剂量,即毒性弱、且疗效不变。本研究招募年满18岁的可手术切除的III期
