Platform Study of Immunotherapy Combinations in Colorectal Cancer Liver Metastases
What this study is about
The goal of this clinical trial is to to learn about different combinations of immunotherapy in patients with colorectal cancer whose cancer has spread to their liver and are planning to have surgery to remove tumor metastases from their liver.
View original scientific description
The goal of this clinical trial is to to learn about different combinations of immunotherapy in patients with colorectal cancer whose cancer has spread to their liver and are planning to have surgery to remove tumor metastases from their liver. The main questions it aims to answer are: * whether these combinations of immunotherapy change the tumor microenvironment in the liver * whether these combinations of immunotherapy are safe and effective when used in colorectal cancer with liver metastases Participants will be randomly assigned to one of the following: * Botensilimab and balstilimab * Botensilimab, balstilimab, and AGEN1423 * Botensilimab, balstilimab, and radiation Participants will be asked to come in to receive drug infusions (and radiation, if applicable) before and after their surgical resection. Participants will be followed for up to 2 years.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Diagnosis of metastatic colorectal adenocarcinoma with liver metastases
- Participant must be planning to undergo a surgical resection of their liver metastases.
- Tumor is non-MSI-H/dMMR
- Presence of measurable disease
- Participants must be willing to consent to additional molecular analyses of tumor samples removed during surgery for research purposes
- Women of childbearing potential (WOCBP), or anyone with a uterus, must not be pregnant or breastfeeding. All participants of childbearing potential must agree to use highly effective contraception during this study
- Participants may not receive chemotherapy, growth factor support, transfusions, or albumin administration within 14 days of start of study treatment.
Exclusion criteria
- Not eligible for surgery
- Any medical condition such as uncontrolled infection, uncontrolled diabetes mellitus or cardiac disease which, in the opinion of the treating physician, would make this protocol unreasonably hazardous for the patient.
- Previous allogeneic tissue/organ transplant
- Previously received PD-1, PD-L1, or CTLA-4 therapy including experimental immunologic agents
- Participants must not have any contraindications to immune checkpoint inhibitors
- Participants must not have active autoimmune disease that has required systemic treatment within 2 years prior to registration. Some exceptions are allowed

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
