Overview

JS212 + capecitabine + oxaliplatin is a combination therapeutic regimen being developed by Shanghai Junshi Bioscience Co., Ltd. for the treatment of metastatic colorectal cancer (mCRC). The regimen consists of JS212, a recombinant humanized bispecific antibody-drug conjugate (ADC) that targets both epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 3 (HER3), combined with the standard XELOX chemotherapy regimen (capecitabine and oxaliplatin). JS212 is designed to deliver a cytotoxic topoisomerase I inhibitor payload directly to tumor cells while simultaneously inhibiting EGFR and HER3 signaling pathways, which may help overcome resistance mechanisms associated with single-target therapies. This combination is currently being evaluated in Phase 2 clinical trials for patients with previously untreated microsatellite stable (MSS) or proficient mismatch repair (pMMR) metastatic colorectal cancer.
