Targeting branched Lewis B/Y glycans with GNX1021: A novel ADC approach for HER2-low gastric cancer (AACR-NCI-EORTC 2025) - "GNX1021 is a first-in-class antibody-drug conjugate (ADC) comprising a bLeB/Y-specific monoclonal antibody (GNX102) linked to monomethyl auristatin E (MMAE) via an enzyme-cleavable linker...GNX1021 was evaluated in vitro for binding, internalization, and cytotoxicity, and in vivo using gastric cancer cell line-derived xenograft (CDX) models, as monotherapy or in combination with trastuzumab deruxtecan (T-DXd)... GNX1021 is a novel glycan-targeting ADC with potent activity against gastric cancer, including HER2-low subtypes. By engaging the bLeB/Y broadly presented on key oncogenic receptors, GNX1021 shows promise as a monotherapy or in combination with protein targeted therapies including HER2-directed agents. These results support its potential to address unmet clinical needs in advanced gastric cancer."
