Real-World tofacitinib study in ulcerative colitis ends early
NCT ID NCT05069259
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how well the drug tofacitinib (Xeljanz) works for people with moderate to severe ulcerative colitis in everyday medical practice in Switzerland. It measured symptom improvement and gut inflammation using stool samples. The study was small with 18 participants and was terminated early, so results are limited.
