K1 Humans K1 Programmed Cell Death 1 Receptor K1 Immunotherapy K1 Angiogenesis AB Immunomodulation has emerged as an active therapeutic option in some solid tumors; however, the efficacy of immunotherapy-based regimens is limited in sarcomas or restricted to a few specific subtypes. IMMUNOSARC was a phase Ib/II trial testing the double inhibition of angiogenesis (sunitinib) and PD-1/PD-L1 axis (nivolumab) in bone and soft-tissue sarcoma (STS). In this latter cohort, the trial met its primary endpoint, with 48% of patients free of progression at 6 months (m). We present here, part of the correlative studies associated with the STS cohort.
