A Study of Induction and Maintenance Treatment of Advanced or Metastatic Non Squamous Non-Small Cell Lung Cancer

This study will estimate the response rate in patients with advanced or metastatic non-squamous Non-Small Cell Lung Cancer. Patients who don't progress after 4 to 6 cycles of induction treatment with pemetrexed, cisplatin and cetuximab will receive maintenance treatment with pemetrexed and cetuximab.
