Summary

This trial will study the effects of a new drug, etrumadenant, on participants with metastatic colorectal cancer.

Who is the study for?
Adults with metastatic colorectal cancer who've had no more than two prior treatments can join this trial. They must have a measurable tumor, be HIV and hepatitis negative, have good organ function and performance status (able to carry out daily activities), and agree to contraception. Exclusions include certain heart conditions, active infections, recent vaccines or surgeries, other cancers within 2 years (except some skin cancers), CNS metastases, autoimmune diseases, or previous treatment with similar drugs.
What is being tested?
The study is testing combinations of Etrumadenant with other cancer drugs like Zimberelimab and Bevacizumab in patients whose disease has progressed after treatment. It's an open-label trial where everyone knows what treatment they're getting; it aims to see how well these drug combos work against advanced colorectal cancer.
What are the potential side effects?
Possible side effects may include allergic reactions to the medication components, increased risk of infection due to immune system effects from Zimberelimab or Etrumadenant, bleeding risks associated with Bevacizumab use on top of general chemotherapy side effects such as fatigue, digestive issues and blood cell count changes.
