E.2 Objective of the trial |

To evaluate two years disease-free survival (DFS) after salvage surgery followed by nivolumab (first cohort of patients), or followed by nivolumab-ipilimumab combination (NIC; second cohort of patients). |
|
E.2.2 | Secondary objectives of the trial |
To evaluate toxicity, overall survival, quality of life. To correlate these endpoints with HPV status. To evaluate DFS in high and low risk subgroups determined by immunoscore, a prognostic test based on type and location of tumor infiltrating lymphocytes; to evaluate DFS in subgroups determined by immunohistochemical expression of PDL1. To characterize Pharmacokinetic of the agents and explore Pharmacodynamic

E.4 | Principal exclusion criteria |
• Recurrent or metastatic carcinoma of the nasopharynx, squamous cell carcinoma that originated from the skin and salivary gland, or non-squamous histologies (eg, mucosal melanoma). • Recurrence or second primary of HNSCC in a non previously irradiated area, or at a dose < 50 Gys • Macroscopic incomplete surgery (no debulking allowed) • Superficial recurrence without nodal recurrence, and without histologic gravity signs (histologic involvement of surgical margins, perineural spread) • Nodal recurrence less than 3 cm, without local recurrence and without capsular rupture at histologic examination • Serious medical adverse conditions, such as severe cardiac and/or pneumologic and/or liver dysfunction. Non exhaustive list, to be appreciated in each center • Subjects with active, known or suspected autoimmune disease. Subjects with 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 are permitted to enroll. • Subjects with a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of study drug administration. Inhaled or topical steroids and adrenal replacement doses > 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease. • 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. • Patients with positive test for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS). • Prior malignancy active within the previous 3 years except for locally curable cancers that have been apparently cured, such as basal or squamous cell skin cancer, superficial bladder cancer, or carcinoma in situ of the prostate, cervix, or breast. • 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). • Patients receiving anti-cancer therapies must be discontinued at least 4 weeks prior to administration of study drug. Palliative, focal radiation therapy, and immunosuppressive doses of systemic corticosteroids, except replacement organotherapy (hydrocortisone and fludrocortisone), must be discontinued at least 2 weeks before administration of study drug. All toxicities attributed to prior anti-cancer therapy other than alopecia and fatigue must have resolved to grade 1 (NCI CTCAE version 4) or to baseline or stabilized before administration of study drug. Subjects with toxicities attributed to systemic prior anticancer therapy which are not expected to resolve and result in long lasting sequelae, such as neuropathy after platinum based therapy, are permitted to enroll. • Use of non-oncology vaccines containing live virus for prevention of infectious diseases within 4 weeks prior to study drug. The use of the inactivated seasonal influenza vaccine (Fluzone®) is allowed.Known or underlying medical condition (e.g., a condition associated with diarrhea or acute diverticulitis) that, in the investigator’s opinion, would make the administration of study drug hazardous to the patient or obscure the interpretation of toxicity determination or adverse events. • Patients requiring concomitant treatment with therapeutic doses of anticoagulants will not be eligible for this clinical trial. Patients treated with low dose of anticoagulants for thrombo-embolic events prophylaxis are allowed. • History of auto immune, immune mediated inflammatory disease including but not limited to colitis, pneumonitis, hepatitis, nephritis, inflammatory of skin, SNC, eyes, glands producing hormons • Active serious infections in particular if requiring systemic antibiotic or antimicrobial therapy • History of severe hypersensitivity reaction to any monoclonal antibody • History of allergy to study drugs components • Treatment with other investigational drugs or treatment in another clinical trial within the past 4 weeks before start of therapy or concomitantly with the trial • Pregnancy or breastfeeding • Psychological, familial or social factor incompatible with informed consent, and regular follow-up.
