New biologic mirikizumab put to the test against standard therapies for IBD
NCT ID NCT07686757
First seen Jul 07, 2026 · Last updated Sep 01, 2026 · Updated 7 times
Summary
This study compares the real-world effectiveness of mirikizumab against standard biologic therapies for adults with ulcerative colitis or Crohn's disease. Researchers will track whether mirikizumab reduces the need for extra medical care, like emergency visits or treatment changes, over 18 months. Participants receive either mirikizumab or another biologic as part of their routine care, and their health data and symptom reports are collected to see which approach leads to better disease control.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Mirikizumab
- What this could lead to
- If mirikizumab works better than current biologics, it could offer a new, more effective option for controlling inflammatory bowel disease and reducing hospital visits.
- What could go wrong
- This is a real-world study, not a tightly controlled trial, so results may be less clear. Mirikizumab may not prove superior to existing treatments, and individual responses vary.

Inclusion Criteria: * Age ≥21 years at the time of enrollment * Confirmed diagnosis of ulcerative colitis (UC) or Crohn's disease (CD) * Eligible for treatment with biologic therapy for IBD, defined as failure of prior conventional therapy and/or prior biologic therapy (excluding IL-23p19 antagonists) * No prior exposure to mirikizumab and no contraindications to mirikizumab * Ability to provide informed consent * Willingness to comply with study procedures and follow-up requirements Exclusion Criteria: * Prior exposure to IL-23p19 antagonists (e.g., mirikizumab, risankizumab, guselkumab) * Prior exposure to small molecule targeted therapies for IBD (e.g., JAK inhibitors or S1P receptor modulators) * Participation in an interventional clinical trial within 90 days prior to enrollment * History of extensive colorectal resection, including: * Total proctocolectomy (for UC), or * Surgical removal of two or more intestinal segments (for CD) * Any condition that, in the investigator's judgment, may compromise patient safety, data integrity, or ability to participate in the study
