This trial is for adults with unresectable, metastatic microsatellite-stable colorectal adenocarcinoma after at least one chemotherapy regimen. Prior checkpoint immunotherapy is excluded; groups include patients with and without active liver metastases.

The idea: oral SR-8541A blocks ENPP1, aiming to preserve signals that activate anticancer immunity. Intravenous botensilimab and balstilimab block CTLA-4 and PD-1 immune brakes. Researchers first escalate doses, then study larger groups for safety and tumor response. Screening tumor tissue is required; post-treatment tissue is optional.

This phase 2 study plans 70 patients. Stingray Therapeutics sponsors it; six US sites are recruiting.
