Samples must be received by the central laboratory before randomization. 7. All baseline laboratory requirements will be evaluated , and must be obtained -14 days of randomization. The screening laboratory values must meet the following criteria: i) WBC ≥ 2000/μL ii) iNeutrophils ≥ 1500/μL iii) Platelets ≥ 100 x 10 ³ / uL iv) Hemoglobin ≥ 9.0 g / dL v) Serum creatinine ≤ 1.5 x ULN or creatinine clearance \> 40 mL / min (using the Cockcroft / Gault ) Women : CrCl = (140 - age in years) x weight in kg x 0.85 72 x serum creatinine in mg / dL Males: CrCl = (140 - age in years) x weight in kg x 1.00 72 x serum creatinine in mg / dL vi) ≤ 1.5 X ULN AST vii) ≤ 1.5 X ULN ALT viii) Total bilirubin ≤ 1.5x ULN (except for subjects with Gilbert 's Syndrome who must have total bilirubin \< 3.0 mg / dL ) h ) pretreatment with radiotherapy or radiosurgery at least 3 weeks must be completed before randomization. i ) Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least four weeks prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 7 days prior to trial treatment. This exception does not include carcinomatous meningitis which is excluded regardless of clinical stability. 3. Age and Reproductive Status 1. Women with reproductive potential ( WOCBP ) should use contraceptive methods based on tables found in Appendix 2 . When a teratogenic drug test is used , and / or a drug for which there is not enough information to assess teratogenicity ( have not been conducted preclinical studies) are required to use a highly effective method of contraception ( failure rate less than 1 % per year). Individual methods of contraception should be determined in consultation with the researcher. 2. The WOCBP must have a negative pregnancy test in serum or urine ( minimum sensitivity 25 IU / L or equivalent units of HCG ) 24 hours before starting the investigational product . 3. Women should not be breastfeeding . 4. Subjects must: 1. Be willing and able to provide written informed consent/assent for the trial. 2. Be \> 18 years of age on day of signing informed consent. 3. Have measurable disease based on RECIST 1.1. 4. Have provided tissue from an archival tissue sample or newly obtained core or excisional biopsy of a tumor lesion. 5. Have a performance status of 0 or 1 on the ECOG Performance Scale. 6\. Demonstrate adequate organ function as defined in Table 1, all screening labs should be performed within 10 days of treatment initiation. Exclusion Criteria: The subject must be excluded from participating in the trial if the subject: 1. Is currently participating in or has participated in a study of an investigational agent or using an investigational device within 4 weeks of the first dose of treatment. 2. Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment. 3. Has had a prior monoclonal antibody within 4 weeks prior to study Day 1 or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier. 4. Has had prior chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to study Day 1 or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to a previously administered agent. * Note: Subjects with ≤ Grade 2 neuropathy are an exception to this criterion and may qualify for the study. * Note: If subject received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy. 5. Has a known additional malignancy that is progressing or requires active treatment. Exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or in situ cervical cancer that has undergone potentially curative therapy. 6. Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least four weeks prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 7 days prior to trial treatment. 7. Has an active autoimmune disease requiring systemic treatment within the past 3 months or a documented history of clinically severe autoimmune disease, or a syndrome that requires systemic steroids or immunosuppressive agents. Subjects with vitiligo or resolved childhood asthma/atopy would be an exception to this rule. Subjects that require intermittent use of bronchodilators or local steroid injections would not be excluded from the study. Subjects with hypothyroidism stable on hormone replacement or Sjorgen's syndrome will not be excluded from the study. 8. Has evidence of interstitial lung disease or active, non-infectious pneumonitis. 9. Has an active infection requiring systemic therapy. 10. Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator. 11. Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial. 12.

Has received prior therapy with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti-Cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) antibody (including ipilimumab or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways). 14.
