FDA批准HPV免疫疗法
一种由人乳头瘤病毒(HPV)感染引起的罕见且可能致命的呼吸系统疾病的首个治疗方法已获得完全批准。美国食品和药物管理局(FDA)批准Precigen的基于非复制腺病毒载体的免疫疗法Papzimeos (zopapogene imadenovec-drba)用于治疗成人复发性呼吸道乳头状瘤病(RRP);不需要进行验证性试验。RRP是由HPV 6型或11型慢性感染引起的,可导致上呼吸道和下呼吸道非癌性肿瘤(乳头状瘤)的复发生长。这种生长会阻塞呼吸道,影响声音功能,导致阻塞性肺炎,在极少数情况下,还会变成恶性的。反复的手术干预需要去除乳头状瘤,但他们没有触及潜在的HPV感染。预防性HPV疫苗可以阻止HPV感染并预防新的RRP病例,但不能有效治疗已经患有RRP的患者。获得批准后,Papzimeos成为唯一治疗RRP的药物。它使用专有的非复制大猩猩腺病毒载体,其大小使其能够传递编码HPV 6和11 (E2, E4, E6和E7)基因的有效载荷。临床前研究表明,该疗法表达的复合蛋白抗原可激活CD8+ T细胞对两种类型的人乳头瘤病毒的反应。由于对Precigen的大猩猩腺载体没有预先存在的免疫力,因此可以反复使用Papzimeos来建立T细胞反应。
