Summary

This trial aims to test one or two drugs (nivolumab with or without ipilimumab) to see if they can help people with colorectal or gastroesophageal cancer delay or

Who is the study for?

This trial is for adults with colorectal or gastroesophageal cancer. For gastroesophageal cancer, a specific gene change is required. Participants will undergo numerous clinic visits and tests including blood, urine, imaging scans, and tissue samples from the digestive tract.

What is being tested?

The study evaluates if nivolumab alone or combined with ipilimumab can delay or avoid surgery in patients. Treatments are given through an IV every 3 weeks for up to 24 weeks. Patients responding well may continue treatment; otherwise, they'll consider surgery.

What are the potential side effects?

Nivolumab and ipilimumab might cause immune-related reactions affecting various organs, infusion-related discomforts, fatigue, gastrointestinal issues like diarrhea or colitis, skin rash and potential hormonal gland problems.
