Blood test guides smarter IBD treatment in landmark trial
NCT ID NCT05180175
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a blood test measuring proteins can help doctors choose the best treatment for people newly diagnosed with inflammatory bowel disease (IBD), including ulcerative colitis and Crohn's disease. 300 patients were split into two groups: one where doctors had the protein test results and used a more aggressive treatment plan for high-risk patients, and another where doctors used standard care. The goal was to see if the personalized approach led to better disease control and quality of life after one year.
