治疗性人源化单克隆抗体研究进展

目前正在研究中的生物技术药物有1/4以上是单克隆抗体药物,临床治疗中人抗鼠抗体反应(HAMA)的出现使鼠源性单克隆抗体的应用受到极大限制.因此,对于疗程长、需反复给药的单克隆抗体药物,人源化是其重要而必然的发展方向.现阶段,已有30余个通过细胞工程和基因工程制备的人源化抗体应用于临床,适应证包括变态反应性疾病、恶性肿瘤、器官移植排斥反应、心血管疾病、病毒感染等难治性疾病.此外尚有近百个人源化抗体药物正处在临床前或临床研究阶段.预计它们将在人类疾病的治疗中发挥重要作用.

Advances in humanized monoclonal antibody for therapeutic uses

Now more than a quarter of biotech drugs are monoclonal antibodies. But clinical reactions of human anti-mouse antibody (HAMA) prevent murine antibodies from human uses for long-term or repeated treatment. Therefore, humanized monoclonal antibodies shall be the development trend for long term or repeated treatment in human. Recent progress in clinical uses and research of humanized monoclonal antibodies are reviewed in this article.
