Can a simple body scan predict IBD drug success?
NCT ID NCT07162701
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study follows 48 adults with active Crohn's disease or ulcerative colitis who are starting biologic or JAK inhibitor therapy. Researchers use a quick, painless bioelectrical impedance scan to measure muscle mass and other body composition changes at the start, 24 weeks, and 52 weeks. The goal is to see if these changes can help predict how well the medication works.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors predict which IBD treatments work best by monitoring simple body measurements like muscle mass.
- What could go wrong
- This is a small, early observational study, not a treatment trial. It may not lead to any changes in clinical practice.
