Ezra Cohen, MD, associate director, Moores Cancer Center,professor of Medicine, University of California, San Diego Health System, discusses tumor biomarker association with clinical outcomes in patients with recurrent and/or metastatic head and neck squamous cell carcinoma treated with afatinib versus methotrexate.

In a biomarker analysis of the LUX-Head and Neck 1 study, researchers sought to determine which patients, whether HPV-positive or HPV-negative, are more likely to benefit from treatment with afatinib versus methotrexate, which is the standard of care, Cohen explains.

In patients who were p16-negative, the response rate with afatinib was approximately 14%; there were almost no responses with methotrexate in this subgroup, Cohen says. Secondly, patients with EGFR amplification had a higher benefit with afatinib. High levels of P10 and low levels of HER3 also served as biomarkers for patients who respond postiviely to afatinib, he adds.
