[Combination strategies for checkpoint inhibition: Current practices and perspectives]. / Combinaisons d'inhibiteurs de points de contrôle immunitaires en oncologie : état de l'art et perspectives.

T-cell checkpoint blockade therapies have revolutionized treatment protocols and prognosis in patients with cancer. Pointed out by the success of PD-1 (programmed cell death-1) plus CTLA-4 (cytotoxic-T-lymphocyte associated antigen 4) blockade in patients with melanoma, the perspective of new synergistic immunotherapy combinations seems to be an important opportunity to improve outcomes for patients. In this article, we first focus on immunotherapy combinations that have shown their efficiency and that are currently approved in solid tumors. Then, we present a summary of emerging targets with reported pre-clinical efficacy and currently evaluated through ongoing clinical trials and other immunomodulatory molecules in the tumor microenvironment.
