What this phase means
Phase 3: this treatment already looked useful in smaller studies. Now it is tested in a large group, often against standard care or a dummy treatment, to see if it should be approved.
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 Mirikizumab, Mirikizumab, or Tirzepatide. The registry lists allocation as randomized. The main purpose of this study is to measure the how well it works and safety of mirikizumab and dummy treatment (placebo) compared with mirikizumab and concomitantly administered tirzepatide in adult participants with moderately to severely active CD and obesity, or overweight.
They plan to enroll about 290 people at 182 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
