Bispecific antibodies (bsAbs) are artificial antibodies with two distinct antigen-binding sites that can bind to different antigens or different epitopes on the same antigen. Based on a variety of technology platforms currently developed, bsAbs can exhibit different formats and mechanisms of action. The upgrading of antibody technology has promoted the development of bsAbs, which has been effectively used in the treatment of tumors. So far, 7 bsAbs have been approved for marketing in the world, and more than 200 bsAbs are in clinical and preclinical research stages. Here, we summarize the development process of bsAbs, application in tumor treatment and look forward to the challenges in future development.
双特异性抗体(bsAbs)是具有两个独特抗原结合位点的人工抗体,能够结合不同的抗原或同一抗原上的不同表位。基于目前开发的多种技术平台,bsAbs 可以表现出不同的形式和作用机制。抗体技术的升级推动了 bsAbs 的发展,使其在肿瘤治疗中得到了有效应用。迄今为止,全球已有 7 种 bsAbs 获准上市,超过 200 种 bsAbs 处于临床和临床前研究阶段。本文总结了 bsAbs 的发展历程、在肿瘤治疗中的应用,并对未来发展面临的挑战进行了展望。
