Summary

This study is for people with active Crohn's disease that hasn't improved with standard treatments. Participants will receive a stem cell transplant followed by a drug called vedolizumab to help keep the disease in remission. The goal is to see if this combination can reduce symptoms and improve quality of life for up to a year.
