摘要
人类基因组中的 24 个 claudin(CLDN)基因编码 26 个具有代表性的 CLDN 家族蛋白。CLDN 是紧密连接处的四跨跨膜蛋白。由于 CLDN6 和 CLDN18.2 等几种 CLDN 异构体在人类癌症中特异性上调,因此开发了针对 CLDN 的单克隆抗体(mAbs)、抗体药物结合体(ADC)、双特异性抗体(bsAbs)和嵌合抗原受体(CAR)T 细胞。本综述将讨论临床试验中的 CLDN1、4、6 和 18.2 靶向研究药物。针对胃癌和其他类型癌症患者的CLDN18.2靶向疗法是这一领域的最前沿。小鼠/人嵌合抗CLDN18.2 mAb zolbetuximab的单药客观反应率(ORR)为9%,与化疗联合使用可提高无进展生存期和总生存期。人/人化抗CLDN18.2 mAb osemitamab以及ADCs AZD0901、IBI343和LM-302的单药客观反应率为28%-60%,已在III期临床试验中进行了测试。此外,针对 CLDN4、6 或 18.2 的 bsAbs、CAR T 细胞及其衍生物也已进入 I 期和/或 II 期临床试验。AZD0901、IBI343、唑贝昔单抗和抗CLDN1 mAb ALE.C04已被美国食品药品管理局授予快速通道指定或优先审评指定。
Claudin 1, 4, 6 and 18 isoform 2 as targets for the treatment of cancer (Review).
The 24 claudin (CLDN) genes in the human genome encode 26 representative CLDN family proteins. CLDNs are tetraspan‑transmembrane proteins at tight junctions. Because several CLDN isoforms, such as CLDN6 and CLDN18.2, are specifically upregulated in human cancer, CLDN‑targeting monoclonal antibodies (mAbs), antibody‑drug conjugates (ADCs), bispecific antibodies (bsAbs) and chimeric antigen receptor (CAR) T cells have been developed. In the present review, CLDN1‑, 4‑, 6‑ and 18.2‑targeting investigational drugs in clinical trials are discussed. CLDN18.2‑directed therapy for patients with gastric and other types of cancer is the most advanced area in this field. The mouse/human chimeric anti‑CLDN18.2 mAb zolbetuximab has a single‑agent objective response rate (ORR) of 9%, and increases progression‑free and overall survival in combination with chemotherapy. The human/humanized anti‑CLDN18.2 mAb osemitamab, and ADCs AZD0901, IBI343 and LM‑302, with single‑agent ORRs of 28‑60%, have been tested in phase III clinical trials. In addition, bsAbs, CAR T cells and their derivatives targeting CLDN4, 6 or 18.2 are in phase I and/or II clinical trials. AZD0901, IBI343, zolbetuximab and the anti‑CLDN1 mAb ALE.C04 have been granted fast track designation or priority review designation by the US Food and Drug Administration.
