Zelgen recently received approval from the National Medical Products Administration for the clinical trial of injectable ZGGS34 for MUC17 positive advanced solid tumors. ZGGS34 is a trispecific antibody drug that can connect tumor cells with T cells, activating T cells to kill tumor cells. Compared to traditional T cell engagers, ZGGS34 introduces a CD28 agonistic antibody, enhancing T cell activation and anti-tumor effects. Preclinical studies have shown that ZGGS34 has significant inhibitory effects in various tumor models and demonstrates good safety characteristics in non-human primates
