Randomized Phase 2 Trial of Pharmacodynamic Separation of Pemetrexed and Intercalated Erlotinib Versus Pemetrexed Alone for Advanced Nonsquamous, Non-small-cell Lung Cancer.

ABSTRACT:

Background

Pharmacodynamic separation of pemetrexed and erlotinib avoids negative cellular interactions and results in antitumor synergy in erlotinib-resistant non-small-cell lung cancer (NSCLC) cells, independent of EGFR (epidermal growth factor receptor) genotype.

Patients and methods

Patients with platinum-treated metastatic nonsquamous NSCLC were randomly assigned 1:2 to pemetrexed alone (500 mg/m² provided intravenously on day 1) or pemetrexed followed by erlotinib (150 mg provided orally once daily on days 2-17) every 21 days. EGFR genotype was centrally confirmed by Sequenom multiplex oncogenotyping assay. The primary end point was progression-free survival (PFS), which would be considered promising for future study if median PFS was ≥ 4.5 months.
