TSR-042 in Addition to Standard of Care Definitive Radiation for Inoperable Endometrial Cancer

Summary

Patients with inoperable endometrial cancer have limited treatment options. PD-L1 expression is common in endometrial cancers and RT induces tumor and systemic changes that induce the immune system. The purpose of this trial is to evaluate anti-PD-1/PD-L1 axis therapy in conjunction of standard of care RT for patients with inoperable endometrial cancer in order to establish the safety and efficacy of inducing an anti-tumor immune response.
