NGR-hTNF in Combination With Standard Chemotherapy to Treat Patients With Advanced Non-small Cell Lung Cancer

Eligible patients will be randomly assigned to a standard chemotherapy regimen plus low-dose (0.8 mcg/m\^2) NGR-hTNF or standard chemotherapy alone, through a centralized randomization process using the following stratification factors: performance status (0 vs 1) and histology (squamous vs non-squamous). In both arms the choice between the two chemotherapy regimens will be based on the histologic subtype: in patients with squamous histology (including also generic diagnosis of NSCLC without further subtype classification) is recommended cisplatin/gemcitabine regimen, in patients with nonsquamous histology (including adenocarcinoma and large-cell carcinoma) is recommended cisplatin/pemetrexed regimen.
