New hope for rare gut disease? small study tests biologic drug
NCT ID NCT07582991
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a drug called ustekinumab in 8 people with a rare, severe form of Behçet's syndrome affecting the gut, along with a blood disorder called myelodysplastic syndrome. The goal was to see if the drug could control gut symptoms and reduce disease activity over 24 weeks. Since there are no standard treatments for this combination, the study aimed to find a safe and effective option, but it is not a cure.
