CCHT(SZ:000661) Ge Long Hui·2025-09-05 10:28Core Viewpoint - Changchun High-tech Industry (Group) Co., Ltd. announced that its subsidiary, Changchun Jinsai Pharmaceutical Co., Ltd., received the acceptance notice for the clinical trial application of GenSci140 from the National Medical Products Administration, indicating progress in the development of a new targeted therapy for cancer [1][2]. Group 1 - GenSci140 is a novel dual-target antibody-drug conjugate that targets the folate receptor alpha (FRα), designed to enhance binding and internalization in tumor cells [1]. - The drug combines Fab fragments targeting different epitopes of FRα with a single-domain heavy chain antibody (VHH), utilizing a cleavable linker and a topoisomerase I (TOPOI) inhibitor payload [1]. - GenSci140 has shown significant anti-tumor effects in various models, including ovarian cancer, regardless of FRα expression levels [2]. Group 2 - Preclinical studies indicate that GenSci140 possesses strong tumor cell binding and internalization activity, along with high plasma stability of the linker technology developed in-house [2]. - The innovative dual-epitope design and effective cytotoxic mechanism suggest that GenSci140 could become a potential best treatment option for FRα-positive cancer patients, particularly those with low to medium FRα expression [2].
