In case of safety issue a -1 dose level will be tested. Phase II : Open label, non randomized, efficacy study of nivolumab in addition to radiotherapy and temozolomide. This phase will start when the RP2D has been defined after the last patients evaluable for DLT achieved the first 6 weeks of treatment (the radio-chemotherapy period) with a DLT rate below 30% during the the phase I study.
