Study of Erlotinib With or Without Investigational Drug (CS-7017) in Subjects With Advanced Non-small Cell Lung Cancer

Phase 2 Study of CS-7017 and Erlotinib in Subjects With Advanced Non-Small Cell Lung Cancer Who Failed First Line Therapy

This is a Phase 2 and open-label (subject will know the treatment he or she is receiving) study. The subject will receive either Erlotinib alone or Erlotinib + CS-7017 in this study.

The study will determine what effect adding CS-7017 to Erlotinib has on safety and length of survival in subjects with advanced non-small cell lung cancer who failed the first treatment.

• ≥ 18 years of age.
• Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2.
