Imatinib plus Cetuximab as a Window of Opportunity Clinical Trial in Head and Neck Cancer

Cetuximab, an approved anti-EGFR receptor monoclonal antibody, is used for the treatment of metastatic cancer, often in conjunction with cytotoxic chemotherapy. It is also employed as a radiosensitizer in the context of definitive radiation therapy for locally advanced cases. However, overcoming resistance to cetuximab, whether intrinsic or acquired, represents a significant challenge in clinical practice. In preclinical studies, the identification of tyrosine 821 (Y821) on the C-terminal of AXL has been linked to resistance to both cetuximab and radiation therapy via signaling through the tyrosine kinase c-Abl.
