Abstract

Checkpoint inhibitors have improved survival for patients with melanoma, non-small-cell lung cancer (NSCLC), bladder, head and neck and other cancers. Antibodies against PD-L1, including atezolizumab, avelumab and durvalumab, are also being developed and have been approved for various cancers. Compared with anti-CTLA-4 drugs, studies with anti-PD-1/PD-L1 agents have suggested higher response rates and improved survival. Targeting PD-L1 rather than PD-1 may also theoretically offer further benefit, with the potential for improved efficacy and reduced toxicity, although this has not been clearly shown by clinical experience to date. Anti-PD-L1 agents have shown good efficacy and manageable toxicity in several tumor types.

摘要

检查点抑制剂已提高了黑色素瘤、非小细胞肺癌(NSCLC)、膀胱癌、头颈癌和其他癌症患者的生存率。针对程序性死亡受体配体1(PD-L1)的抗体,包括阿替利珠单抗、阿维鲁单抗和度伐鲁单抗,也正在研发中,并且已被批准用于多种癌症。与抗细胞毒性T淋巴细胞相关蛋白4(CTLA-4)药物相比,抗程序性死亡蛋白1(PD-1)/PD-L1药物的研究表明其具有更高的缓解率和更长的生存期。理论上,靶向PD-L1而非PD-1可能会带来更多益处,有可能提高疗效并降低毒性,尽管迄今为止临床经验尚未明确证实这一点。抗PD-L1药物在多种肿瘤类型中已显示出良好的疗效和可管理的毒性。
