Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

BACKGROUND/RATIONALE:

Treatment outcomes of patients with inflammatory bowel disease (IBD) have improved enormously during the past decade due to the use of anti-tumour necrosis factor (anti-TNF) therapy. As a result, 67 to 91% of paediatric patients and 66% of adult patients is still in sustained remission two years after the initiation of anti-TNF therapy. Prolonged use of anti-TNFs comes with disadvantages such as dose dependent susceptibility to infections and dermatological adverse effects. Preliminary, mostly uncontrolled studies suggest that dose reduction by dosing interval lengthening is a realistic option in a relevant proportion of patients with IBD, provided that intensive follow-up is applied.

OBJECTIVE:

To evaluate whether a faecal calprotectin (FC) guided strategy of anti-TNF dosing interval lengthening is non-inferior in maintaining remission in patients with IBD, compared with an unchanged dosing interval.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

STUDY DESIGN:

International, multi-centre, prospective, partially randomised patient-preference trial.

STUDY POPULATION:

Study population: Eligible patients are aged 12-25 years with luminal Crohn's disease (CD) or ulcerative colitis (UC), who have three consecutive faecal calprotectin (FC) results in the target range (i.e. \<250 µg/g for CD patients; \<150 µg/g for UC patients) over a period of 6 months at study entry or recently confirmed endoscopic remission.

DE-ESCALATION STRATEGY:

In patients treated with adalimumab, the dosing interval will be lengthened from 2 to 3 weeks. In patients treated with infliximab, the dosing interval will be lengthened from 8 to 12 weeks. FC rapid tests will be performed every 4 weeks and rapid tests for anti-TNF trough levels will be performed every 12 weeks.

MAIN STUDY ENDPOINTS:

The primary outcome is the cumulative incidence of out-of-range FC results at 48 weeks follow-up. Secondary endpoints include time to get out-of-range FC results, cumulative incidence of anti-TNF associated adverse effects, proportion of patients progressing from out-of-range FC to loss-of-response and identification of predictors of successful de-escalation.

ETHICAL CONSIDERATIONS:

Patients with reduced anti-TNF exposure may have a higher risk of out-of-range FC results and, on the other hand, may benefit from fewer hospital visits or injections and possibly a decrease in adverse effects of anti-TNF therapy. Tight monitoring of FC levels (i.e. 4-weekly) will allow institution of re-escalation before the patient manifests clinical signs of relapse. This study cannot be conducted without the participation of minors and young adults, who typically have a short disease duration. Early treatment with anti-TNF agents possibly modifies the course of their disease, which makes provision for safe deescalation.

Intervention group

In patients treated with adalimumab, the dosing interval will be lengthened from 2 to 3 weeks. In patients treated with infliximab, the dosing interval will be lengthened from 8 to 12 weeks. Consists of two groups: Patients randomised to the intervention group and patients allocated to the intervention group based on preference.

Infliximab

Intervention Type BIOLOGICAL

Dosing interval lengthening from 8 to 12 weeks

Adalimumab

Intervention Type BIOLOGICAL

Dosing interval lengthening from 2 to 3 weeks

Control group

Unchanged dosing interval. Consists of two groups: Patients randomised to the control group and patients allocated to the control group based on preference.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Aged 12-25 years
* Diagnosed with luminal Crohn's disease or ulcerative colitis
* Treated with either 8-weekly infliximab or 2-weekly adalimumab
* Current anti-TNF agent as first ever anti-TNF agent or prior anti-TNF agent discontinued for reason other than primary non-response or secondary loss-of-response
* No previous attempts to lengthen the dosing interval
* Three consecutive faecal calprotectin (FC) results in the target range (i.e. \<250 μg/g for CD patients; \<150 μg/g for UC patients) in the previous 6 months or confirmed endoscopic remission within 2 months before study entry (i.e. simple endoscopic score for Crohn's disease (SES-CD) \<3 points for CD patients; ulcerative colitis endoscopic index of severity (UCEIS) ≤1 point for UC patients)
* Absence of symptoms associated with active IBD (judged by the local IBD-team)
* Written informed consent granted

Exclusion Criteria

* Perianal fistula
* Presence of ileostomy or ileoanal pouch (as FC cut-off is not validated for small bowel faeces)
* Any inflammatory comorbidity, such as rheumatoid arthritis
* Current treatment with corticosteroids (prednisone or budesonide)
* Current pregnancy
