Study Stopped
Considering the efficacy results of the induction phase (allowed use of corticosteroids as concomitant medication) in the study population and since IMU-838 did not show superiority over placebo, the OLE was prematurely closed by the sponsor.

Outcome Measures
Primary Outcomes (1)
Induction Phase: Symptomatic Remission and Endoscopic Healing at Week 10
Composite endpoint: Proportion of patients with both, symptomatic remission (Mayo rectal bleeding subscore = 0, and Mayo stool frequency subscore of 0 or 1) and endoscopic healing (Modified Mayo endoscopy subscore of 0 or 1) at Week 10. All patients who were randomized to 30 mg/day and 45 mg/day were used for the assessment of the primary efficacy endpoint

Study Arms (8)
10 mg IMU-838 (Induction)
EXPERIMENTALTwo 5 mg tablets once daily of IMU-838 for 10 to 22 weeks depending on symptomatic remission at Weeks 10 or 22. Patients will receive only half of their assigned full dose during the first week of treatment.
30 mg IMU-838 (Induction)
EXPERIMENTALTwo 15 mg tablets once daily of IMU-838 for 10 to 22 weeks depending on symptomatic remission at Weeks 10 or 22. Patients will receive only half of their assigned full dose during the first week of treatment.
45 mg IMU-838 (Induction)
EXPERIMENTALTwo 22.5 mg tablets once daily of IMU-838 for 10 to 22 weeks depending on symptomatic remission at Weeks 10 or 22. Patients will receive only half of their assigned full dose during the first week of treatment.
placebo (Induction)
PLACEBO COMPARATORThe placebo tablets will be identical to the IMU-838 tablets in terms of appearance, constitution of inactive ingredients, and packaging.
10 mg IMU-838 (Maintenance)
EXPERIMENTALTwo 5 mg tablets once daily of IMU-838 until Week 50 or ulcerative colitis relapse.
30 mg IMU-838 (Maintenance)
EXPERIMENTALTwo 15 mg tablets once daily of IMU-838 until Week 50 or ulcerative colitis relapse.
placebo (Maintenance)
PLACEBO COMPARATORThe placebo tablets will be identical to the IMU-838 tablets in terms of appearance, constitution of inactive ingredients, and packaging. Patients who have received placebo during the induction phase will be 're-randomized' to continue to receive placebo (in a blinded fashion).
30 mg IMU-838 (Open-label)
EXPERIMENTALTwo 15 mg tablets once daily of IMU-838 or one 30 mg tablet IMU-838 once daily for up to 10 years and up to 3 years in UK sites

You may not qualify if:
- Diagnosis of Crohn's disease, inflammatory bowel disease type unclassified, ischemic colitis, microscopic colitis, radiation colitis or diverticular disease-associated colitis
