Disclosed are monoclonal antibodies that bind specifically to macrophage stimulating protein receptor (or RON—Recepteur d' Origine Nantais). Also provided are the chimeric antigen receptors, bispecific antibodies, bivalent antibodies and biTE thereof, as well as pharmaceutical compositions and uses of said antibodies for the treatment of cancer and fibrosis and an ex vivo method of evaluating the status of a cancer patient using said antibodies. In particular, two monoclonal antibodies, 7G8 and 6D4, demonstrating good therapeutic efficacy in inhibiting tumour growth in human xenograft mice models and sensitivity in human xenograft mouse tumour imaging models are provided.
本研究公开了与巨噬细胞刺激蛋白受体(或 RON-Recepteur d' Origine Nantais)特异性结合的单克隆抗体。此外,还提供了嵌合抗原受体、双特异性抗体、二价抗体及其双TE,以及上述抗体用于治疗癌症和纤维化的药物组合物和用途,以及使用上述抗体评估癌症患者状况的体外方法。特别是提供了两种单克隆抗体 7G8 和 6D4,这两种抗体在人类异种移植小鼠模型中抑制肿瘤生长方面表现出良好的疗效,在人类异种移植小鼠肿瘤成像模型中表现出敏感性。
