What this phase means
Phase 4: the treatment is already approved. This study asks new questions — longer-term effects, other diseases, or how it compares in everyday care.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are Vedolizumab IV, or Vedolizumab SC. The registry lists allocation as randomized. Ulcerative Colitis (UC) and Crohn's Disease (CD) are long-term conditions in the gut that can cause diarrhea, swelling (inflammation), bleeding from the anus, and belly pain.
They plan to enroll about 200 people at 101 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
