程序性死亡蛋白1抑制剂被推荐用于治疗复发性/难治性经典霍奇金淋巴瘤(RRcHL),但缓解的持续时间尚不明确。研究人员开展了一个为期2年的2期临床试验,研究派姆单抗用于HL患者的疗效和安全性。共有210位患者,分成了3个队列。中位随访时间为27.6个月,客观缓解率(ORR)为71.9%(95% CI, 65.3-77.9);完全缓解率(CRR)为27.6%;部分缓解率为44.3%。1、2、3队列的O

程序性死亡蛋白1抑制剂被推荐用于治疗复发性/难治性经典霍奇金淋巴瘤(RRcHL),但缓解的持续时间尚不明确。

研究人员开展了一个为期2年的2期临床试验,研究派姆单抗用于HL患者的疗效和安全性。共有210位患者,分成了3个队列。中位随访时间为27.6个月,客观缓解率(ORR)为71.9%(95% CI, 65.3-77.9);完全缓解率(CRR)为27.6%;部分缓解率为44.3%。

1、2、3队列的ORR和CRR分别是76.8%和26.1%、66.7%和25.9%、73.3%和31.7%。所有患者的中位缓解持续时间为16.5个月(范围0.0+个月 -27.0+个月),1、2、3队列的分别是22.1个月、11.1个月、24.4个月。

所有CR患者的中位无进展存活期未达到,部分缓解的患者的为13.8 个月 (95% CI, 12.0-22.1),病情稳定的患者的为10.9个月 (95% CI, 5.6-11.1) 。所有患者和任一队列的中位总体存活期未达到。

所有等级的治疗相关副反应(TRAEs)共见于153位(72.9%)患者;3/4级TRAEs见于25位(11.9%)患者,最常见的是中性粒细胞减少(5例[2.4%])和腹泻(3例[1.4%]);无死亡病例。14位(6.7%)患者因TRAEs而终止治疗。

综上所述,本研究证实了派姆单抗单药治疗RRcHL的抗肿瘤活性、缓解的持久性和可控的安全性,而且未考虑既往采用的治疗和是否对化疗耐药。
