日前,吉利德科学(Gilead Sciences)旗下的Kite公司宣布,其CAR-T疗法Yescarta,作为一线疗法,在治疗高危大B细胞淋巴瘤(LBCL)患者的2期临床试验中获得积极结果。接受一次Yescarta输注后,85%的患者获得临床缓解(n=27),其中74%的患者获得完全缓解。新闻稿指出,这是CAR-T疗法作为一线疗法获得的首个积极临床结果。
Yescarta是FDA批准的第二款CAR-T疗法,已经获得批准作为三线疗法,治疗难治性LBCL患者。它通过给从患者体内获取的T细胞装上靶向CD19的抗体嵌合受体(CAR),将这些T细胞变为杀伤肿瘤的细胞疗法。
在名为ZUMA-12的多中心、开放标签、单臂2期临床试验中,Yescarta在随访时间至少一个月时达到74%的完全缓解率。而且,在中位随访时间为9.3个月时,70%获得缓解的患者仍然处于缓解中。在中位随访时间为9.5个月时,中位无进展生存期、总生存期和缓解持续时间均尚未达到。
