About this study
Official title: A Phase Ib/II Trial of M7824 in Solid Tumors With Microsatellite Instability With Consensus Molecular Subtype 4 Metastatic Colorectal Cancer in Combination With Radiation, or in Colorectal Cancer Patients With Detectable Circulating Tumor DNA Following Definitive Therapy
This phase Ib/II trial studies how well anti-PD-L1/TGFbetaRII fusion protein M7824 (M7824) works in treating patients with colorectal cancer (or with other solid tumors with microsatellite instability) that has spread to other places in the body or cannot be removed by surgery. Immunotherapy with monoclonal antibodies, such as M7824, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

PRIMARY OBJECTIVES:
-Objective response rate (ORR) in microsatellite instability-high (MSI-H) mCRC patients who have progressed on immune checkpoint blockade therapy (Cohort A).
OR
-ORR in patients with treatment-refractory, consensus molecular subtype 4 (CMS4) mCRC patients coadmnistered SBRT (Cohort B).
OR

- MSI-H mCRC who are refractory to prior immune checkpoint blockade therapy (Cohort A).
OR o Treatment-refractory, CMS4 mCRC coadministered SBRT (Cohort B). While SBRT is preferred, IMRT or 3D conformal techniques may be utilized at the discretion of the treating radiation oncologist depending on the dose to surrounding normal tissues.

OUTLINE:
