The antibody drug market is rapidly expanding, and various antibody engineering technologies are being developed to create antibodies that can provide better benefit to patients. Although bispecific antibody drugs have been researched for more than 30 years, currently only a limited number of bispecific antibodies have achieved regulatory approval. Of the few successful examples of industrially manufacturing a bispecific antibody, the "common light chain format" is an elegant technology that simplifies the purification of a whole IgG-type bispecific antibody. Using this IgG format, the bispecific function can be introduced while maintaining the natural molecular shape of the antibody. In this article, we will first introduce the outline, prospects, and limitations of the common light chain format. Then, we will describe the identification and optimization process for ERY974, an anti-glypican-3 × anti-CD3ε T cell-redirecting bispecific antibody with a common light chain. This format includes one of Chugai's proprietary technologies, termed ART-Ig technology, which consists of a method to identify a common light chain, isoelectric point (pI) engineering to purify the desired bispecific IgG antibody from byproducts, and Fc heterodimerization by an electrostatic steering effect. Furthermore, we describe some tips for de-risking the antibody when engineering a T cell redirecting antibody.

设计具有共同轻链的双特异性抗体:抗 CD3 epsilon 和抗 GPC3 双特异性抗体 ERY974 的鉴定和优化

抗体药物市场正在迅速扩大,各种抗体工程技术正在开发中,以创造可以为患者提供更好益处的抗体。虽然双特异性抗体药物的研究已经超过30年,但目前只有有限数量的双特异性抗体获得监管批准。在工业制造双特异性抗体的少数成功例子中,“通用轻链形式”是一种优雅的技术,可简化整个 IgG 型双特异性抗体的纯化。使用这种 IgG 形式,可以在保持抗体的自然分子形状的同时引入双特异性功能。在本文中,我们将首先介绍常见轻链格式的概述、前景和局限性。然后,我们将描述 ERY974 的鉴定和优化过程,ERY974 是一种具有共同轻链的抗 glypican-3 × anti-CD3ε T 细胞重定向双特异性抗体。此格式包括 Chugai 的一项专有技术,称为 ART-Ig 技术,该技术包括一种识别常见轻链的方法、等电点 (pI) 工程以从副产物中纯化所需的双特异性 IgG 抗体,以及通过静电转向进行 Fc 异二聚化影响。此外,我们描述了在设计 T 细胞重定向抗体时降低抗体风险的一些技巧。它包括一种识别共同轻链的方法、等电点 (pI) 工程以从副产物中纯化所需的双特异性 IgG 抗体,以及通过静电转向效应的 Fc 异二聚化。此外,我们描述了在设计 T 细胞重定向抗体时降低抗体风险的一些技巧。它包括一种识别共同轻链的方法、等电点 (pI) 工程以从副产物中纯化所需的双特异性 IgG 抗体,以及通过静电转向效应的 Fc 异二聚化。此外,我们描述了在设计 T 细胞重定向抗体时降低抗体风险的一些技巧。
