Availability of adequate FFPE tumour‐derived material (tumour blocks or slides) from a biopsy, surgery or fine needle aspirate for analysis of PD‐L1 testing by IHC
Patients with other severe concurrent disorders that occurred during the prior six months before enrolment (myocardial infection, severe or unstable angor, coronarian or peripheric arterial bypass operation, NYHA class 3 or 4 congestive heart failure, transient or constituted cerebral ischaemic attack, at least grade 2 peripheral neuropathy, psychiatric or neurological disorders preventing the patient from understanding the trial, uncontrolled infections) are not eligible.
Serious or uncontrolled systemic disease judged as incompatible with the protocol by the investigator
Another previous or concomitant cancer, except for basocellulare cancer of the skin or treated cervical cancer in situ, or appropriately treated localized low‐grade prostate cancer (Gleason score inferior at 6), unless the initial tumour was diagnosed and definitively treated more than 5 years previously, with no evidence of relapse.

Uncontrolled infectious status
All concurrent radiotherapy
Concurrent administration of one or several other anti‐tumour therapies.

Patients are excluded if they have active brain metastases or leptomeningeal metastases. Patients with brain metastases are eligible if metastases have been treated and there is no magnetic resonance imaging (MRI) evidence of progression for (lowest minimum is 4 weeks or more) after treatment is complete and within 28 days prior to the first dose of nivolumab and ipilimumab administration. There must also be no requirement for immunosuppressive doses of systemic corticosteroids (superior at 10 mg/day prednisone equivalents) for at least 2 weeks prior to study drug administration.
Patients should be excluded if they have an active, known or suspected autoimmune disease. Patients are permitted to enrol if they have vitiligo, type I diabetes mellitus, residual hypothyroidism due to autoimmune condition only requiring hormone replacement, psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger
Patients should be excluded if they have a condition requiring systemic treatment with either corticosteroids (superior at 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of study drug administration. Inhaled or topical steroids and adrenal replacement doses superior at 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease.
Patients should be excluded if they are positive test for hepatitis B virus surface antigen (HBV sAg) or hepatitis C virus ribonucleic acid (HCV antibody) indicating acute or chronic infection
Patients should be excluded if they have known history of testing positive for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS)
Patients should be excluded if they have a lung disease that is symptomatic or may interfere with the detection or management of suspected drug‐related pulmonary toxicity
Allergies and Adverse Drug Reaction
History of allergy to study drug components
Severe spinal hypoplasia and/or hemorrhagic tumours.
