Abstract

Background

Patients with advanced squamous cell carcinoma (SCC) of the lung have limited treatment options. Although treatment with the EGFR tyrosine kinase inhibitor erlotinib is indicated in the second- or third-line or maintenance setting, the benefit is limited. Afatinib is a novel, selective, orally bioavailable, ErbB family blocker, irreversibly blocking EGFR (ErbB1), HER2 (ErbB2) and HER4 (ErbB4). Based on its promising preclinical profile and clinical activity in trials of SCC of the head and neck and lung, we seek to determine if the irreversible inhibition of the ErbB family translates into clinical benefit for patients with SCC of the lung.

Methods

This trial will compare the efficacy of afatinib versus erlotinib as second-line treatment for patients with SCC of the lung, as measured by progression-free survival. Key patient eligibility criteria include: advanced NSCLC squamous or mixed histology, completion of at least 4 cycles of platinum-based doublet chemotherapy, eligible to receive EGFR-directed therapy as second-line therapy, ECOG PS 0–1, adequate organ function, availability of archived tumour tissue for correlative studies and no prior EGFR-directed therapy. Secondary endpoints are comparison of overall survival, objective response rate, disease control rate, tumour shrinkage, assessment of health-related quality of life and safety in both treatment groups. Eligible patients will be randomized (1:1) to receive either afatinib or erlotinib and stratified based on race (East Asian vs. other). Eight hundred patients are planned to be enrolled globally. Independent radiological assessment of the primary endpoint will be completed in a treatment-blinded manner. An independent data monitoring committee will monitor safety and efficacy of the trial.
