Summary

This early-stage study tests a new drug called zasocitinib (TAK-279) in 20 adults with active Crohn's disease who have not responded to other treatments. The main goal is to see if the drug is safe and how it affects inflammation in the gut. Participants will take the drug for 12 weeks and undergo a colonoscopy to check for changes.
