Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
cumulative incidence of out-of-range fecal calprotectin results at 48 weeks follow-up
Out-of-range FC results are defined as fecal calprotectin above the target range (i.e. \>250 μg/g for CD patients; \>150 μg/g for UC patients) and at least 100 μg/g increase compared with the previous result, unless the previous result was already above the target range.
48 weeks
Secondary Outcomes (5)
Time to get out-of-range fecal calprotectin results
up to 48 weeks
Cumulative incidence of anti-TNF-associated respiratory infections and dermatological adverse effects at 48 weeks follow-up
48 weeks
Evolution of FC and anti-TNF trough levels in the first 16 weeks after reverting to previous dosing interval
Up to 48+16 weeks
Proportion of patients developing loss-of-response in the first 16 weeks after reverting to the previous dosing interval
Up to 48+16 weeks
Identification of predictors of successful de-escalation.

Study Arms (2)
Intervention group
EXPERIMENTALIn 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.
Control group
NO INTERVENTIONUnchanged dosing interval. Consists of two groups: Patients randomised to the control group and patients allocated to the control group based on preference.
Interventions
Dosing interval lengthening from 8 to 12 weeks
Dosing interval lengthening from 2 to 3 weeks
Eligibility Criteria
You may qualify if:
- 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
You may not qualify if:
- 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
