There is an unmet need to develop new treatments for metastatic prostate cancer. With the development of targeted radioligand therapies, bispecific T cell engagers, antibody–drug conjugates and chimeric antigen receptor T cell (CAR T) therapies, tumor-associated cell surface antigens have emerged as new therapeutic targets in metastatic prostate cancer. Ongoing and completed clinical trials targeting prostate-specific membrane antigen (PSMA), six transmembrane epithelial antigens of the prostate 1 (STEAP1), kallikrein-related peptidase 2 (KLK2), prostate stem cell antigen (PSCA), and delta-like protein 3 (DLL3) in metastatic prostate cancer were reviewed. Strategies for sequential or combinational therapy were discussed.
针对转移性前列腺癌,开发新的治疗方法存在未满足的临床需求。随着靶向放射性配体疗法、双特异性T细胞衔接器、抗体-药物偶联物以及嵌合抗原受体T细胞(CAR T)疗法的发展,肿瘤相关细胞表面抗原已成为转移性前列腺癌的新治疗靶点。本文综述了针对转移性前列腺癌中前列腺特异性膜抗原(PSMA)、前列腺六次跨膜上皮抗原1(STEAP1)、激肽释放酶相关肽酶2(KLK2)、前列腺干细胞抗原(PSCA)以及Delta样蛋白3(DLL3)的正在进行或已完成的临床试验,并探讨了序贯或联合治疗策略。
