NCT ID NCT03571373

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study follows 1,500 children newly diagnosed with inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis, to understand why some respond well to treatments while others develop complications. Researchers will collect medical data and biological samples to identify early predictors of disease course and treatment outcomes. The goal is to improve care and tailor treatments to each child's individual risk.

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
This research could help doctors predict which children with IBD will respond to specific treatments or face complications, enabling more personalized care.
What could go wrong
As an observational study, it cannot prove cause and effect. Findings may take years to emerge and may not apply to all patients.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria Inception cohort: Newly diagnosed patient, \<18 years of age, with a likely diagnosis of IBD or a confirmed diagnosis of IBD can be included in the study. In order to be eligible to continue in the study the subject must meet all of the following criteria: * Diagnosis is based on history, physical examination, laboratory, endoscopic, radiological and histological features according to the revised Porto criteria (1) * Diagnosis has been made or is confirmed within 2 months of inclusion * Data on all diagnostic procedures are available for inclusion in the database * Informed consent of patient (if indicated) and parents has been obtained * Concerning the patients of whom biological specimens will be included: patients have not started IBD treatment yet Inclusion Criteria Safety Registry: Any child with IBD \<19 years old with complications as detailed in the agreed safety monitoring list (or future updates of the list of conditions) can be reported. For the initial reporting of incident cases no patient identifiable details will be required. Exclusion Criteria Inception cohort: * Inability to read and understand the patient and family information sheets (for example insufficient knowledge of national language, where no health advocate or family member is available to translate and ensure full understanding of the study) * Informed consent of patient or parents has not been obtained when required * Patients on similar treatments as for IBD but for other conditions, or known with conditions directly affecting the IBD (e.g. immunodeficiency or major gastrointestinal resections) Exclusion Criteria Safety registry: none.
