Methods for Prediction of Clinical Outcome to Epidermal Growth Factor Receptor Inhibitors by Cancer Patients

Disclosed are biomarkers, methods and assay kits for the identification of cancer patients who are predicted to benefit, or not to benefit, from the therapeutic administration of an epidermal growth factor receptor (EGFR) inhibitor. The biomarkers of the present invention include detection of EGFR and HER 2 gene amplification and polysomy, EGFR protein expression, EGFR mutations, phosphorylated Akt protein expression, and various combinations of such biomarkers, as well as the combination of these biomarkers with mutations in the tyrosine kinase domain of the EGFR gene. Increased EGFR gene copy number, increased HER2 gene copy number, increased EGFR, protein expression, activated AKT protein expression (phosphorylated AKT) and EGFR mutations are all associated with better outcome for cancer patients treated with EGFR inhibitors. The invention provides a diagnostic paradigm based on each of these tests and combinations of these tests to select cancer patients who will benefit from EGFR inhibitor therapy, as well as a diagnostic paradigm to select cancer patients who will not benefit from EGFR inhibitor therapy.

Mig6 and therapeutic efficacy

We identify markers capable of guiding the decision to incorporate epidermal growth factor receptor (EGFR) inhibitors, in particular EGFR tyrosine kinase inhibitors (TKIs), into chemotherapeutic regimens. Mitogen-inducible gene 6 (Mig6), a negative regulator of EGFR, is selectively upregulated during the development of resistance to the EGFR tyrosine kinase inhibitor (TKI) erlotinib, resulting in decreased EGFR phosphorylation. The ratio of Mig6 / EGFR expression highly correlates with erlotinib sensitivity. A low Mig6 / EGFR ratio correlates with a high response rate to gefitinib and a marked increase in progression-free survival for patients. The ratio of Mig6 to EGFR is a major predictor of biologic and clinical responses to EGFR inhibitors.
