About this trial

The goal of this clinical trial is to learn whether the combination of balstilimab, botensilimab, and agenT-797 is safe and effective in treating adults with previously treated metastatic colorectal cancer that is microsatellite stable (pMMR) and has spread to the liver.

The main questions it aims to answer are:

* What proportion of participants experience tumor shrinkage (objective response rate) based on imaging assessments? * What side effects occur with this combination treatment, including immune-related and cytokine-related reactions?

All participants in this study will receive the combination treatment. There is no comparison group.

Participants will:

* Receive balstilimab, botensilimab, and agenT-797 in repeating 42-day treatment cycles * Undergo imaging scans (such as CT or MRI) to assess tumor response * Have blood samples collected to monitor safety and evaluate biomarkers * Provide tumor tissue samples for research * Be monitored for side effects throughout the study * Participate in follow-up visits to assess survival after treatment completion

Eligibility criteria

Qualifiers

Adults ≥18 years of age with histologically confirmed metastatic colorectal cancer with liver metastases, including evidence of active liver disease if previously treated locally

At least one measurable lesion per RECIST v1.1, with ≥1 target lesion in the liver

Tumor confirmed as microsatellite stable (MSS)/proficient mismatch repair (pMMR)

Received ≥1 prior line of systemic therapy including fluorouracil, oxaliplatin, and irinotecan (not necessarily in combination), and prior EGFR inhibitor or bevacizumab if eligible, unless contraindicated

Disqualifiers

Tumor is dMMR/MSI-high

Prior treatment with PD-1, PD-L1, CTLA-4 inhibitors, or other immunotherapy agents

Evidence of bowel obstruction, impending obstruction, or recent obstruction (within 3 months)

Refractory ascites requiring frequent paracentesis or recent escalation of diuretics
