RNA疫苗在胰腺癌中诱导长寿命抗肿瘤T细胞
治疗癌症的疫苗目前正在开发中,有可能针对各种癌症类型的特定突变进行个性化治疗。先前的一项I期试验报告,个体化RNA新抗原疫苗是安全的,并且在与胰腺腺癌延迟复发相关的胰腺癌患者中刺激抗肿瘤CD8+ T细胞(16例中有8例,随访1.5年)。患者先接受手术,然后接受atezolizumab(一种PD-L1抑制抗体)、autogene cevumeran(一种个体化新抗原RNA疫苗)和改良的FOLFIRINOX(化疗)治疗。在这项发表在《自然》杂志上的新研究中,研究人员在延长的随访中分析了治疗前后的样本,以进一步研究这些疫苗诱导的T细胞的特征。使用疫苗诱导T细胞治疗的应答者(n = 8)与不使用这种T细胞治疗的应答者相比,无复发生存期延长(中位13.4个月,P = 0.007),在中位随访时间为3.2年时,有6名应答者无癌症。自体基因cevumeran诱导了长期和强大的CD8+ T细胞反应,与延迟3.2年的胰腺腺癌复发相关。至关重要的是,疫苗诱导了长寿命T细胞克隆(具有多年寿命,中位数为7.7年),这些克隆作为假定的记忆T细胞持续存在,并长期保持这些效应功能。一项全球随机II期试验目前正在进行中。
