What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study looks back at the medical records of over 1,000 people hospitalized with inflammatory bowel disease (IBD) in China. The goal is to understand the features, treatments, and outcomes of patients whose IBD does not respond well to standard therapies. By analyzing real-world data, researchers hope to identify factors linked to harder-to-treat disease and improve future care.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could help doctors better identify which treatments work best for hard-to-treat inflammatory bowel disease.
What could go wrong
This is an observational study that looks back at existing records, so it cannot prove cause and effect. Results may not apply to all patients.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Eligible patients had an established diagnosis of CD or UC based on clinical, endoscopic, radiologic, and histopathologic findings in accordance with European Crohn's and Colitis Organization guidance. Refractory IBD was defined according to the IOIBD consensus criteria. Patients were classified as having refractory IBD if they fulfilled at least one of the following criteria: failure of at least two biologic or small-molecule therapies with different mechanisms of action; recurrence after at least two surgeries in adult patients with CD; complex perianal disease; or chronic antibiotic-refractory pouchitis. Psychological factors were not included because they could not be assessed consistently in this retrospective study. Patients were excluded if they had participated in clinical trials or received investigational drugs, had concomitant malignancy, severe immunodeficiency, or other systemic autoimmune diseases, or were diagnosed with IBD-unclassified.

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)
