Adjuvant Immunotherapy After Salvage Surgery in Head and Neck Squamous Cell Carcinoma (ADJORL1)

Adjuvant Immunotherapy After Salvage Surgery in Head and Neck Squamous Cell Carcinoma : Phase 2 Trial Evaluating the Efficacy and the Toxicity of Nivolumab Alone, and of the Combination Nivolumab and Ipilimumab

Two randomized trials of reirradiation after salvage surgery have been conducted by the GETTEC and GORTEC collaborative groups, both members of the French HN Intergroup: The first trial compared reirradiation and a "wait and see attitude" and was published in 2008 [1]. The second trial compared two modalities of reirradiation. Our hypothesis is that adjuvant treatment with immunotherapy will lead to a DFS similar to that observed in previous trials of post-operative reirradiation with possibly lower toxicity.

• Recurrence of bad prognosis justifying an adjuvant treatment:
• clinically infiltrative recurrence or second primary; or nodal recurrence upper or equal to 3 cm, or association of local and nodal recurrence;
• superficial recurrence, but histologic gravity signs on surgical specimen indicating a high risk of recurrence after salvage surgery (histologic involvement of surgical margins or margins less than 3mm, perineural spread or vascular emboli, multiples invaded nodes). Nodal recurrence without tumor recurrence and inferior to 3cm, but with capsular rupture at histologic examination.

Sexually active males patients must agree to use condom during the study and for at least 7 months after the last study treatment administration. Also, it is recommended their women of childbearing potential partner use a highly effective method of contraception.
• Women who are breastfeeding should discontinue nursing prior to the first dose of study drug and until 5 months after the last dose.
• Patient should understand, sign, and date the written informed consent form prior to any protocol-specific procedures performed. Patient should be able and willing to comply with study visits and procedures as per protocol.
