          1. Adult men and women ≥18 years.

          2. Patients with a histologically confirmed Renal Cell Carcinoma with a clear-cell
             component.

          3. Patients with metastatic (AJCC stage IV) Renal Cell Carcinoma, with at least one
             measurable lesion by CT Scan or MRI according to RECIST 1.1 or with clinically
             apparent disease that can be reliably monitored by the investigator.

             IL-2, IFN-α), vaccine therapy or treatment with cytotoxics are allowed. Patients
             intolerant to prior systemic anti-angiogenic treatment can also be eligible (except
             hypersensitivity to other monoclonal antibodies). A maximum of 25% of patients with
             more than 2 prior systemic treatments will be recruited per sites.

          5. Patients with Eastern Cooperative Oncology Group (ECOG) performance status ≤2.

          6. Favorable, intermediate or poor risk group patients measured by the international
             metastatic renal cell carcinoma database consortium (IMDC) model.

          7. Patients with brain metastases will be eligible if they are: asymptomatic, without
             edema, not on corticosteroids, not be eligible for radiation therapy/surgery and not
             receiving active treatments.

          8. Patients who have progressed following radiation therapy. Palliative, focal radiation
             therapy, and immunosuppressive doses of systemic corticosteroids, except replacement
             organotherapy (hydrocortisone and fludrocortisone), must be discontinued at least 2
             weeks prior to the first nivolumab administration.

             treatment, and for at least 31 weeks (≈ 7 months) for males and 23 weeks (≈ 5 months)
             for females after the last dose of study drug. Azoospermic males and women of
             childbearing potential who are continuously not heterosexually active are exempt from
             contraceptive requirements.

         10. Women of childbearing potential must have a negative serum pregnancy test done within
             24 hours prior to the first dosing.

         11. Women who are breastfeeding should discontinue nursing prior to the first dose of
             study drug and until 6 months after the last dose.

             condition requiring hormone replacement, psoriasis not requiring systemic treatment,
             or conditions not expected to recur in the absence of an external trigger are however
             eligible for this trial).

          2. Patients with uncontrolled adrenal insufficiency.

          3. Patients with known history of testing positive for human immunodeficiency virus (HIV)
             or known acquired immunodeficiency syndrome (AIDS).

          4. Patients with positive tests for hepatitis B virus surface antigen (HBV sAg) or
             hepatitis C virus ribonucleic acid (HCV RNA) indicating active or chronic infection.

          5. Patients having received prior therapy with anti-PD-1, anti-PD-L1, anti-PD-L2,
             anti-CD137, or anti-CTLA-4 antibody (or any other antibody or drug specifically
             targeting T-cell co-stimulation or checkpoint pathways).

          6. Patients having received any non-oncology vaccine therapy used for prevention of

          8. Patients with other prior malignancy active within the previous 3 years except for
             locally curable cancers that have been apparently cured, such as basal or squamous

         12. Known or underlying medical condition (e.g., a condition associated with diarrhea or
             acute diverticulitis) that, in the investigator's opinion, would make the
