What this trial studies

This clinical trial aims to evaluate the safety and effectiveness of different combinations of immunotherapy in patients with colorectal cancer that has metastasized to the liver and are scheduled for surgery. Participants will be randomly assigned to receive either Botensilimab and Balstilimab, a combination of these two drugs with AGEN1423, or the same two drugs with radiation. The study will assess changes in the tumor microenvironment and monitor participants for up to two years after treatment. The goal is to identify promising immunotherapy combinations that could improve patient outcomes.

Who should consider this trial

Good fit: Ideal candidates are patients diagnosed with metastatic colorectal adenocarcinoma with liver metastases who are planning to undergo surgical resection.

Not a fit: Patients who are not eligible for surgery or have uncontrolled medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective treatment options for patients with colorectal cancer liver metastases.

How similar studies have performed: Other studies have shown promise with immunotherapy approaches in similar contexts, but this specific combination is being tested for the first time.
