MA03.01 EPICAL Trial. A Phase Ib StudyCombining Anti-Epidermal Growth Factor (EGF) Vaccination With Afatinib in EGFR-Mutant Non-Small Cell Lung Cancer

Abstract

Stage IIIB-IV non-small cell lung cancer patients with mutations in the EGF receptor gene (EGFR) usually derive clinical benefit from to tyrosine kinase inhibitors (EGFR TKIs) but ultimately relapse. In preclinical studies, we have showed that anti-EGF antibodies generated by vaccination significantly increased the antitumor activity of TKIs in EGFR-mut cell lines, blocking EGFR, Erk1/2, Akt and STAT3 activation and delaying emergence of resistance. Based on these findings, the EPICAL trial was initiated (ClinicalTrials.gov number, NCT03623750) .
