A Study Testing How BI 655130 Works in Patients With Fistulizing Crohn's Disease
Condition: Crohn Disease
MeSH terms: Crohn Disease
Intervention: Spesolimab; Placebo
Intervention description: Spesolimab 1200 milligram intravenously every 4 weeks (week 0, 4, 8, 12, 16 and 20). At week 12 Placebo patients without combined perianal fistula remission were switched to spesolimab and were treated with spesolimab 1200 milligram intravenously every 4 weeks (week 12, 16 and 20).; Placebo intravenously every 4 weeks (week 0, 4, 8). At week 12 achievement of combined perianal fistula remission was determined, patients without combined perianal fistula remission were switched to spesolimab and were treated with spesolimab 1200 milligram intravenously every 4 weeks (week 12, 16 and 20). Patients with combined perianal fistula remission remained on Placebo and were treated with placebo intravenously every 4 weeks (week 12, 16 and 20).

Summary:

      This is a study in adults with Crohn's Disease who also have fistulas near the anus. The
      study has 2 parts. The first part is to find out more about what causes the fistulas. In this
      part of the study, tissue samples are taken from patients. The second part of the study tests
      whether a medicine called spesolimab (BI 655130) helps patients with Crohn's Disease.

      Participants get study medication for 24 weeks. The participants are put into 2 groups. It is
      decided by chance who gets into which group. One group gets an intravenous drip that contains
      spesolimab every 4 weeks. The other group gets a placebo drip every 4 weeks. The placebo drip
      looks like the spesolimab drip, but contains no medicine.

      The doctors regularly examine fistulas of the participants. The results of the fistula
      examinations are compared between the groups. The doctors also check the general health of
      the patients.
