EGFR Inhibitor

Cetuximab MMAE is an antibody-drug conjugate (ADC) targeting EGFR, formed by the random conjugation of the Cetuximab (HY-P9905) antibody and VcMMAE (HY-15575) via reduced interchain cysteines. Cetuximab MMAE binds to EGFR, blocks ligand interactions, inhibits downstream signal transduction, mediates receptor internalization, and delivers MMAE to induce G₂/M phase cell cycle arrest, inhibit microtubule polymerization, interfere with mitosis, and exert radiosensitizing effects. Cetuximab MMAE limits the toxicity of free MMAE to EGFR-expressing cells and circumvents EGFR resistance mechanisms. Cetuximab MMAE is applicable to research related to EGFR⁺ tumors.
