RATIONALE: Pemetrexed disodium and sorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Sorafenib may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving pemetrexed disodium together with sorafenib may kill more tumor cells.
PURPOSE: This randomized phase II trial is studying pemetrexed disodium and sorafenib to see how well they work compared with pemetrexed disodium alone as second-line therapy in treating patients with stage IIIB or stage IV non-small cell lung cancer.

OBJECTIVES:
Primary
Secondary
Tertiary
OUTLINE: This is a randomized, multicenter study. Patients are stratified according to ECOG performance status (0 vs 1) and North Central Cancer Treatment Group membership. Patients are randomized to 1 of 2 treatment arms.
Blood and tissue samples are collected for pharmacokinetic analysis and research studies. Gene expression assays and polymorphism studies (e.g., using polymerase chain reaction) of circulating peripheral blood mononuclear cells are conducted for reduced folate carrier, multidrug resistance-associated protein, folate receptor, BCRP, folylpolyglutamate synthase, MTHFR, methionine synthase, methylthioadenosine phosphorylase, TS, dihydrofolate reductase, GARFT, endothelial nitric oxide synthase, angiotensinogen, dimethylarginine dimethylaminohydrolase, vascular endothelial growth factor (VEGF), and VEGF receptor. Enzyme-linked immunosorbent assays and immunohistochemistry are also conducted.
After completion of study treatment, patients are followed periodically for up to 5 years.
