New hope for Tough-to-Treat Crohn's? drug shows promise in small bowel

This study tested the drug upadacitinib in people with Crohn's disease that only affects the small bowel, a type that is often harder to treat. Researchers compared 3 patients with small-bowel Crohn's to others with Crohn's in different areas, using ultrasound to measure bowel inflammation before and after 12 weeks of treatment. The goal was to see if upadacitinib works equally well for both groups.
