A Study of Pemetrexed and Carboplatin/Cisplatin or Gemcitabine and Carboplatin/Cisplatin With or Without IMC-1121B in Participants Previously Untreated With Recurrent or Advanced Non-Small Cell Lung Cancer (NSCLC)

The purpose of this study is to determine if participants with Stage IV NSCLC have a better outcome when treated with IMC-1121B in combination with pemetrexed + carboplatin/cisplatin or gemcitabine + carboplatin/cisplatin than when treated with pemetrexed + carboplatin/cisplatin or gemcitabine + carboplatin/cisplatin alone.
