Randomized phase II trial of erlotinib with and without entinostat in patients with advanced non-small-cell lung cancer who progressed on prior chemotherapy.

ABSTRACT:

Purpose

Histone deacetylase inhibitors (HDACis) have been shown to overcome resistance to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) linked to epigenetic changes and epithelial-mesenchymal transition (EMT) state. This randomized phase II study evaluated the outcome of erlotinib with and without the isoform selective HDACi, entinostat.

Patients and methods

Previously treated patients with stage IIIB/IV non-small-cell lung cancer, no prior EGFR-TKIs, and performance status ≤ 2 were randomly administered erlotinib 150 mg on days 1 through 28 plus entinostat 10 mg orally on days 1 and 15 every 28 days (EE) or erlotinib plus placebo (EP). The primary end point was 4-month progression-free survival (PFS) rate with additional end points including 6-mont
