For the Arm P (nivolumab and ipilimumab), patients must have metastatic or unresectable non-small cell lung carcinoma (NSCLC)

Exclusion Criteria:

Evidence of complete or partial bowel obstruction

Patients with primary central nervous system (CNS) tumor or CNS tumor involvement; however, patients with metastatic CNS tumors may participate in this study if the patient is:
