Duligotuzumab (Anti-EGFR & HER3)

Duligotuzumab is a dual-action humanized IgG1 antibody that blocks ligand binding to the epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 3 (HER3) . By inhibiting these interactions, it disrupts signalling from all ligand-dependent HER dimers and induces antibody-dependent cell-mediated cytotoxicity. It exhibits enhanced efficacy in EGFR inhibitor-resistant SCCHN and NSCLC models, with potential benefits for tumors with high neuregulin 1 (NRG1) expression. MW: 144.78 KD.
