Official title

A Randomized Phase II Study of Anti-PD-1 and Limited Metastatic Site Radiation Therapy Versus Anti-PD-1 Alone for Patients With Microsatellite Instability-high (MSI-H) and Mismatch Repair Deficient (dMMR) Metastatic Solid Tumors

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

To determine if the out-of-field ORR is improved with the addition of radiation therapy to anti-PD-1 for patients with MSI-H/dMMR metastatic solid tumors. Determine the rates of in-field tumor control, disease control (stable disease, partial response, complete response), durability of disease response, progression-free survival, overall survival, and to assess quality of life and toxicity. Determine the chronology and profile of the radiation-associated immune response.
