Phase I/II clinical trial - Sein métastatique triple négatif

The combination of chemotherapy with PD-1 immune checkpoint blockade agents demonstrated promising results especially in the neo-adjuvant and early metastatic setting in TNBC. However, a substantial proportion of patients do not derive benefit from this approach.;CD73 is an adenosine-generating enzyme overexpressed in several cancers and associated with poor prognosis and reduced anti-tumor immunity in TNBC. Monoclonal antibodies directed against CD73 could help to reprogram the tumor microenvironement by decreasing the adenosine mediated immunosuppression, particularly as a synergistic immunotherapeutic combination with immune checkpoint blockade.;The SYNERGY trial investigates the role of an anti-CD73 (MEDI9447) in a randomized phase II trial evaluating the efficacy and safety of the combination of chemotherapy (paclitaxel + carboplatin) with immunotherapy (durvalumab [anti-PD-L1] +/- MEDI9447 [anti-CD73]) in previously untreated locally recurrent inoperable or metastatic TNBC.;A large translational research program is planned including baseline and dynamic biomarkers
