         11. Patients must have adequate organ function : creatinine clearance > 50 mL/min
             (Cockcroft formula), Neutrophiles count > 1500/mm3; Platelets > 100 000/mm3 ;
             Hemoglobin > 9 g/dL; hepatic enzymes < 3N with total bilirubin ≤ 1.5 × ULN (upper
             limit of normal) except subjects with documented Gilbert's syndrome (≤ 5 × ULN) or

         12. Recovered from all toxicities associated with prior treatment, to acceptable baseline
             status, or a National Cancer Institute Common Terminology Criteria for Adverse Events
             (NCI CTCAE v4.0) Grade of 0 or 1, except for toxicities not considered a safety risk,
             such as alopecia or vitiligo

         13. Females of childbearing potential who are sexually active with a nonsterilized male
             partner must use a highly effective method of contraception for 28 days prior to the
             first dose of investigational product, and must agree to continue using such
             precautions for 6 months after the final dose of investigational product; cessation of
             contraception after this point should be discussed with a responsible physician.
             Periodic abstinence, the rhythm method, and the withdrawal method are not acceptable
             methods of contraception. They must also refrain from egg cell donation for 6 months
             after the final dose of investigational product. Men receiving nivolumab and who are
             sexually active with women of childbearing potential will be instructed to adhere to
             contraception for a period of 31 weeks after the last dose of nivolumab.

        Exclusion Criteria:

          1. Patients with primitive peritoneal, pericardial, testis or tunica vaginalis
             mesothelioma

          2. Patients with a recent history of other malignancies except adequately treated
             non-melanoma skin cancer, and curatively treated in-situ cancer. Patients with
             prostate adenocarcinoma diagnosed less than 5 years could be included in case of
             localized prostate cancer with good outcome according the Amico classification: ≤ T2a
             and Gleason Score ≤6 and PSA blood level ≤10 ng/ml, and treated with curative intent
             (surgery or radiotherapy) without chemotherapy. Patients with history of solid tumors,
             including adenocarcinoma, treated with curative intent and without any evidence of
             disease >5 years can be included as well.

             radiotherapy with no evolution within the 3 months before inclusion, and asymptomatic
             patient

          4. History of primary immunodeficiency, history of organ transplant that requires
             therapeutic immunosuppression and the use of immunosuppressive agents within 28 days

             from other immune therapy.

          5. Subjects with a condition requiring systemic treatment with either corticosteroids (>
             10 mg daily prednisone equivalent) or other immunosuppressive medications within 14
             days of randomization. Intranasal/inhaled or topical steroids, and adrenal replacement
             steroid doses ≤ 10 mg daily prednisone equivalent, are permitted in the absence of

             lupus erythematosis or Wegener's granulomatosis. Subjects with type I diabetes
             mellitis, or hypothyroidism only requiring hormone replacement, or skin disorders
