erlotinib and sorafenib in chemonaive patients with locally advanced or metastatic non small cell lung cancer

Conditions: Non-Small Cell Lung Cancer

Summary: patients with advanced or metastatic (stage iiib-iv) non small cell lung cancer who have not received prior chemotherapy will be treated with erlotinib 150 mg once a day and sorafenib 400 mg twice a day. the objectives of the study are to assess the efficacy and safety of this combination treatment. additional exploratory study objectives are correlation of biomarkers and imaging modalities potentially predictive for response and (progression free) survival.
