Run by ImmunoRegister gUG · NCT07319442 · Data updated 2026-11-12
This registry collects real-world health and treatment information from adults with Crohn's disease, ulcerative colitis, or indeterminate colitis in Germany to see how care, effectiveness, safety, and costs play out in routine practice.

Is this trial a fit for you?
✓Likely a good fit
Adults in Germany diagnosed with Crohn's disease, ulcerative colitis, or indeterminate colitis who receive care from participating physicians are the intended participants.
✕Probably not a fit
Patients with other gastrointestinal disorders, pediatric patients, or people not receiving care at participating centers (including those outside Germany) are unlikely to benefit from participation or enrollment.

What this trial studies
CEDUR is a multicenter, web-based, prospective registry enrolling adult patients with Crohn's disease, ulcerative colitis, or indeterminate colitis across Germany. Physicians and patients provide clinical data, quality-of-life measures, treatment patterns, and safety outcomes during routine care. The registry also captures pharmacoeconomic information to study cost and resource use over time. Aggregated data are used to monitor care quality and long-term therapy outcomes under real-world conditions.
Why it matters
Potential benefit: If successful, the registry could help doctors and patients choose and manage long-term treatments by revealing real-world effectiveness, safety, and cost patterns.
How similar studies have gone: Other national and international IBD registries have provided valuable real-world insights into treatment effectiveness, safety, and healthcare use, so this approach is established rather than novel.
