Objectives

Primary

1. Compare the progression-free survival of epidermal growth factor receptor (EGFR) FISH-positive or -negative patients with advanced non-small cell lung cancer treated with erlotinib hydrochloride versus pemetrexed disodium as second-line therapy.

Secondary

1. Compare the overall survival, confirmed response rate, and adverse event profile in these patients based on EGFR-FISH status (positive vs negative).
2. Compare the progression-free survival, overall survival, confirmed response rate, and adverse event profile in these patients based on EGFR expression as measured by immunohistochemistry (IHC).
3. Compare the progression-free survival, overall survival, confirmed response rate, and adverse event profile in these patients based on EGFR gene mutation status.
4. Evaluate the prognostic effect of EGFR copy number, as measured by FISH, on the outcome of these patients.
5. Evaluate the prognostic effect of EGFR expression, as measured by IHC, on the outcome of these patients.
6. Evaluate the prognostic effect of EGFR mutation status on the outcome of these patients.
7. Prospectively test the hypothesis that functionally relevant polymorphisms in the genes encoding for pemetrexed disodium targets, as well as genes encoding for one or more of the key enzymes involved in the transport, activation, and inactivation of pemetrexed disodium, either singly or in combination, play a role in the efficacy and/or toxicity of pemetrexed disodium.
8. Prospectively test the hypothesis that functionally relevant polymorphisms in the EGFR gene as well as genes encoding for one or more of the key enzymes involved in the metabolism of erlotinib hydrochloride, either singly or in combination, play a role in the efficacy and/or toxicity of erlotinib hydrochloride.
9. Evaluate proteomic signatures in blood samples as predictors of survival and response to treatment with erlotinib hydrochloride.
10. Evaluate thymidylate synthase, dihydrofolate reductase, GAR formyltransferase, and methylthioadenosine phosphorylase gene expression in tumor samples, as measured by IHC or quantitative polymerase chain reaction, as predictors of survival and response to treatment with pemetrexed disodium.
11. Evaluate the Ras mutation status, EGFR mutation status, and epithelial to mesenchymal transition status (E-cadherin expression and vimentin expression) in tumor samples, as measured by IHC, as predictors of survival and response to treatment with erlotinib hydrochloride.

Outline

This is a multicenter study. Patients are stratified according to FISH status (negative vs positive), ECOG performance status (0 vs 1 vs 2), gender, smoking status (never smoked vs light smoker [≤ 15 pack years] vs heavy smoker [> 15 pack years]), disease histology (adenocarcinoma vs other), and best response to prior chemotherapy (complete response/partial response vs stable disease vs progressive disease). Patients are randomized to 1 of 2 treatment arms.

• Arm I: Patients receive oral erlotinib hydrochloride once daily on days 1-21. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
• Arm II: Patients receive pemetrexed disodium IV over 10 minutes on day 1. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

Tumor tissue samples are collected at baseline for correlative laboratory studies, including analysis of epidermal growth factor receptor (EGFR) gene expression by FISH; EGFR protein expression by immunohistochemistry (IHC); EGFR and K-ras mutation status; epithelial to mesenchymal transition status (E-cadherin expression and vimentin expression) by IHC; thymidylate synthase, dihydrofolate reductase, and GAR formyltransferase gene expression by quantitative polymerase chain reaction; and methylthioadenosine phosphorylase gene expression by IHC.

After completion of study therapy, patients are followed every 3 months until disease progression and then every 6 months for up to 5 years.
