About this study

Official title: Digestive Evolution of Children With Crohn's Disease or Ulcerative Colitis Whose Anti-TNFα Was Switched to Ustekinumab Due to Paradoxical Psoriasis: Real Life Data

Inflammatory bowel diseases (IBD) include Crohn's disease (CD) and ulcerative colitis (UC). They cause abdominal pain and chronic diarrhea and/or rectal bleeding, which can lead to weight loss and malnutrition. IBD affects people of all ages but usually appears before the age of 30, most often between the ages of 14 and 24. Childhood IBD is generally considered to be more progressive than adult IBD. Although there is no cure for IBD, many medications can help reduce inflammation and relieve IBD symptoms. Anti-TNF drugs (infliximab and adalimumab) are used early in high-risk patients or when standard treatments have failed. Cutaneous side effects are common in pediatrics (>10%), primarily psoriasiform eruptions (41%), often exudative, affecting skin folds and scalp, recurrent skin infections (20%), and eczematous eruptions (10%). Only 5% of patients need to discontinue treatment due to these side effects. In such cases, the recommended treatment is ustekinumab (European guidelines). While this treatment has been described as effective in patients who have failed anti-TNFα therapy, little data is available on the gastrointestinal and dermatological outcomes of patients on anti-TNFα therapy who switch to ustekinumab for dermatological reasons.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of patients maintaining UC or CD control between anti-TNF-α discontinuation (M0) and 3-6 months of ustekinumab treatment (M3-M6)

    Severity scores for Crohn disease (PCDAI: The Pediatric Crohn's Disease Activity Index 0 to 100)

    Measured: at baseline Month 0

  2. Proportion of patients maintaining UC or CD control between anti-TNF-α discontinuation (M0) and 3-6 months of ustekinumab treatment (M3-M6)

    Severity scores for ulcerative colitis (PUCAI: Pediatric Ulcerative Colitis Activity Index 0 to 65).

    Measured: at Month 6

  3. Proportion of patients maintaining UC or CD control between anti-TNF-α discontinuation (M0) and 3-6 months of ustekinumab treatment (M3-M6)

    Severity scores for Crohn disease (PCDAI: The Pediatric Crohn's Disease Activity 0 to 100)

    Measured: at baseline Month 0

  4. Proportion of patients maintaining UC or CD control between anti-TNF-α discontinuation (M0) and 3-6 months of ustekinumab treatment (M3-M6)

    Severity scores for ulcerative colitis (PUCAI: Pediatric Ulcerative Colitis Activity Index0 to 65).

    Measured: at baseline Month 0

Secondary outcomes (4)
  1. Specify the dermatological evolution of patients with IBD after stopping anti-TNFα and introduction of ustekinumab for paradoxical psoriasis resistant to usual treatments.

    The digestive status of patients will be assessed by disease-specific severity scales, namely the Pediatric Crohn's Disease Activity (PCDAI)(from 0 to 100) for patients with Crohn's disease

    Measured: at baseline Month 0

  2. Specify the dermatological evolution of patients with IBD after stopping anti-TNFα and introduction of ustekinumab for paradoxical psoriasis resistant to usual treatments.

    The digestive status of patients will be assessed by disease-specific severity scales, Pediatric Ulcerative Colitis Activity Index (PUCAI) (from 0 to 85) for children with UC.

    Measured: at Month 6

  3. Specify the dermatological evolution of patients with IBD after stopping anti-TNFα and introduction of ustekinumab for paradoxical psoriasis resistant to usual treatments.

    The digestive status of patients will be assessed by disease-specific severity scales, Pediatric Ulcerative Colitis Activity Index : PUCAI (from 0 to 85) for children with UC.

    Measured: at baseline Month 0

  4. Specify the dermatological evolution of patients with IBD after stopping anti-TNFα and introduction of ustekinumab for paradoxical psoriasis resistant to usual treatments.

    The digestive status of patients will be assessed by disease-specific severity scales, namely the Pediatric Crohn's Disease Activity (PCDAI) (from 0 to 100) for patients with Crohn's disease

Questions about this trial

What is this clinical trial studying?

A study testing switch of anti TNF for ustekinumab for paradoxical psoriasis. in people with Chronic Inflammatory Bowel Diseases, run by Centre Hospitalier Universitaire de Nice at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 25 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Christine Chiaverini, Dr (04 92 03 47 02, chiaverini.c@chu-nice.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of patients maintaining UC or CD control between anti-TNF-α discontinuation (M0) and 3-6 months of ustekinumab treatment (M3-M6) (time frame: at baseline Month 0). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
