Brief summary: This is a multicenter study assessing the efficacy of nivolumab in association with relatlimab.

Detailed description: This multicenter, prospective, open-labeled 2-arm, randomized non-comparative phase II trial. This phase II trial is based on a 2-stage Simon's optimal design. Randomization 1:1 with 1 patient randomized in experimental arm A (association of nivolumab plus relatlimab) and 1 patient randomized in arm B (treatment by nivolumab alone).

Eligibility criteria: Inclusion Criteria:

1. Histology: participant with soft tissue sarcoma histologically confirmed and reviewed by the RRePS Network as recommended by the French NCI (Inca),
2. Presence of mature tertiary lymphoid structures (TLS). Except if presence of TLS have been already confirmed by Biopathological platform at Bergonié Institute, presence of TLS should be confirmed by central review based on FFPE (Formalin-Fixed Paraffin-Embedded) tumor tissue sample (archived or newly obtained by biopsy for research purpose).
