Brief summary

Phase II,single arm study designed to explore the activity of TSR-042, an immunotherapy agent, in patients with a diagnosis of advanced or metastatic clear cell sarcoma (CCS).

Detailed description

Phase II, single arm, not randomized, European multicentric study designed to explore the activity of TSR-042, a human monoclonal anti-PD-1 inhibitor, in a population of patients with a diagnosis of advanced/metastatic clear cell sarcoma (CCS).

Interventions

TSR-042 is an IgG4 humanized monoclonal antibody that binds with high affinity to PD-1, resulting in inhibition of binding to PD-L1 and PD-L2.
