Who might be able to join this trial:
- You have been diagnosed with stage IIB, IIC, or III colon cancer that has a specific genetic feature called "mismatch repair deficiency" (dMMR) or "microsatellite instability-high" (MSI-H), confirmed by laboratory testing
- Your colon cancer was completely surgically removed between 4 and 12 weeks before starting the study treatment
- A tissue sample from your surgery is available for testing
- You are generally well enough to carry out light activity or self-care (your doctor will assess this)
- Your blood counts are within acceptable ranges — including white blood cells, platelets, and red blood cells (a blood transfusion beforehand is allowed if needed)
- Your kidney function is within acceptable ranges, based on blood or urine tests
- Your liver function is within acceptable ranges, based on blood tests
- You are at least 18 years old

Who may not be able to join:
- You received treatment (such as chemotherapy or radiation) for your colon cancer before surgery

- You have been diagnosed with another blood cancer or solid tumour within the last 5 years
- You have an autoimmune disease (where your immune system attacks your own body) that has needed medication to control it in the past 2 years — note: some milder autoimmune conditions may still be acceptable (confirm with trial site)
- You currently have an active hepatitis B or hepatitis C infection
- You have taken steroid tablets or other immune-suppressing medicines in the 7 days before your first dose
