Measurable disease is defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded). Each lesion must be >= 10 mm when measured by computed tomography (CT), magnetic resonance imaging (MRI) or caliper measurement by clinical exam; or >= 20 mm when measured by chest x-ray. Lymph nodes must be >= 15 mm in short axis when measured by CT or MRI
• Patients must have at least one “target lesion” to be used to assess response on this protocol as defined by RECIST version 1.1.

Initial treatment may include chemotherapy, chemotherapy and radiation therapy, and/or consolidation/maintenance therapy. Chemotherapy administered in conjunction with primary radiation as a radio-sensitizer WILL be counted as a systemic chemotherapy regimen
• Patients are allowed to have up to three prior cytotoxic regimens for management of recurrent or persistent disease. Hormonal therapies will not count toward the prior regimen limit

• Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 3 x institutional upper limit of normal (ULN) unless liver metastases are present, in which case it must be =< 5 x ULN (within 14 days prior to first treatment)
• Serum creatinine =< 1.5 x institutional upper limit of normal (ULN) (within 14 days prior to first treatment)

• Archival tissue, 15-20 unstained formalin-fixed paraffin-embedded (FFPE) slides, must be available. If archival tissue is not available, patient will be required to undergo
• Subject is willing and able to comply with the protocol for the duration of the study including undergoing treatment, procedures (including on-treatment biopsy), and scheduled visits and examinations including follow up
• Patients must have been enrolled or agree to consent to the companion genomic profiling study Memorial Sloan Kettering Cancer Center (MSKCC) Institutional Review Board (IRB) #12-245
• Patients must have signed an approved informed consent and authorization permitting release of personal information

Exclusion Criteria

• Involvement in the planning and/or conduct of the study (applies to both Bristol-Myers Squibb staff and/or staff at the study site)
• Known mismatch repair (MMR)-deficient patient and / or microsatellite instability-high (MSI-H) will be excluded. Results of IMPACT #12-245 do not need to have resulted prior to enrollment. If results of IMPACT #12-245 shows MSI-H and / or MMR-deficient and patient has already started study, patient can continue on treatment
• Prior enrollment in the present study or another clinical study with receipt of an investigational product during the last 4 weeks
• Any previous treatment with an IDO, PD-1 or PD-L1 inhibitor, or any anti-CTLA4
