A Study to Test Whether Spesolimab Helps People With Crohn's Disease Who Have Symptoms of Bowel Obstruction

Stopped early · Phase 2 · Has a placebo group

Conditions studied: Fibrostenotic Crohn´s Disease

In brief

This study is open to adults, between 18 and 75 years of age, who have narrowings in the small bowel (strictures) due to Crohn's disease. Strictures can lead to bowel obstruction (blockage). People whose symptoms got worse because of strictures can join the study. Participants get standard treatment for Crohn's disease and the strictures. The purpose of the study is to test whether the strictures improve further when treated with a medicine called spesolimab added to standard treatment. Participants are in the study for about 1 year and 4 months. In the first 3 months, participants get standard treatment only. After 3 months, participants whose condition improved are put into 2 groups randomly, which means by chance. One group gets spesolimab added to their standard treatment. The other group gets placebo added to their standard treatment. Both spesolimab and placebo are given as infusions into a vein. Placebo infusions look like spesolimab infusions but do not contain any medicine. For the first 2 months, participants get the infusions every month. Thereafter, participants get the infusions every 2 months. During the study, participants have about 11 visits to the study site. The doctors regularly check participants' health and take note of any unwanted effects. At 3 of the visits, doctors take images of the bowel using Magnetic Resonance Imaging and with an endoscope. At these visits, the doctors also take a small sample of bowel tissue (biopsy). The participants note their symptoms of Crohn's disease and how the symptoms affect daily life in an electronic diary. At the end of the study, results from the diaries and bowel imaging are compared between the spesolimab group and the placebo group.
