Summary

This trial will enroll 20 patients with gastrointestinal cancers who have completed all standard treatments but still have evidence of the disease. Patients will receive intravenous atezolizumab and bevacizumab once every 21 days for a maximum of 12 months.

Who is the study for?
Adults who've completed all standard treatments for certain GI cancers (like colorectal, stomach, liver cancer) with curative intent but still have detectable ctDNA. They must be in good physical condition, not pregnant or breastfeeding, willing to use contraception and not have any active infections or severe health conditions that could interfere with the trial.
What is being tested?
The trial is testing Atezolizumab and Bevacizumab on patients with GI cancers who are ctDNA positive after standard treatment. It's an open-label study where everyone gets the drugs through IV every 21 days for up to a year unless their disease returns or side effects become too much.
What are the potential side effects?
Possible side effects include high blood pressure, bleeding risks like nosebleeds or coughing up blood, potential immune system reactions leading to inflammation in organs like lungs or liver, infection risk increase due to weakened immune defenses, and allergic reactions.
