Trial summary

Infliximab (IFX) is highly effective in inducing and maintaining remission in patients with inflammatory bowel disease (IBD). However, a large proportion of patients will eventually lose response to IFX. Therefore, strategies to improve the outcome of maintenance treatment with IFX are required. Read more about this study

About this study

Official title: Precision Dosing Versus Conventional Dosing of Infliximab Maintenance Therapy: a Randomized Controlled Multicenter Study in Patients With IBD in Clinical Remission

Infliximab (IFX) is highly effective in inducing and maintaining remission in patients with inflammatory bowel disease (IBD). However, a large proportion of patients will eventually lose response to IFX. Therefore, strategies to improve the outcome of maintenance treatment with IFX are required. Retrospective analyses suggest that adjusting IFX treatment in order to achieve IFX trough levels (TL) above a well-defined therapeutic threshold will improve the outcome of IFX treatment.

Read the detailed description

Aim of this study is to investigate the efficacy of "precision dosing" IFX maintenance treatment in comparison with standard IFX maintenance treatment in IBD patients in clinical remission.

This study will be an open, randomized, controlled trial. Inclusion criteria: Patients aged ≥18 years with a diagnosis of Crohn's disease (CD) or ulcerative colitis (UC) based on endoscopy and pathology, receiving scheduled IFX therapy for ≥14 weeks, in clinical remission based on a Harvey Bradshaw Index (HBI) score ≤4 or a Partial Mayo (PM) score ≤2, for CD and UC, respectively. Exclusion criteria: Dilatation or resectional surgury in the past year and patients with a stoma/pouch.

Patients in the intervention arm will receive individualized treatment with variable IFX dosing AND/OR intervals guided by a Bayesian pharmacokinetic model, aiming to achieve an IFX TL of 3 µg/ml. Patients in the control group will continue to receive the same IFX treatment regimen that was given prior to inclusion without dose adaptation. In the control group, treatment adjustments will only be made in case of signs of active disease, in accordance to current routine care but these patients will be considered as failures to their treatment.

Primary endpoint: Proportion of patients with sustained clinical remission (based on HBI or PM). Secondary endpoints include: annual costs of IFX treatment per patient, total annual medical costs, side effects, (sustained) biochemical remission, adverse events, quality of life, IFX trough level and IFX antibodies (with an assay allowing presence of drug).

Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Participation will result in additional blood sampling, since IFX serum concentration will be measured every 8 weeks. All other laboratory tests can be considered as routine care. Patients in the intervention group with IFX TLs >3 will receive treatment de-escalation (interval elongation and/or dose reduction) as indicated by the Baysian model. Current evidence indicates that an IFX TL of 3 suffices. Patients in the intervention group with TLs <3 will receive treatment escalation (interval shortening and/or dose increase). We hypothesize that this will result in a higher chance of remaining in clinical remission.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

    Patients in the PRECISION dosing arm will recieve model based dosing, whereas proactive adjustments in treatment can be made by measuring the Infliximab concentration.

What is being measured

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

  1. Sustained clinical remission for the precision dosing group vs. the conventional IFX maintenance dosing group

    Sustained clinical remission based on HBI (Crohn's disease) or PM score (Ulcerative Colitis)

    Measured: 52 weeks

Secondary outcomes (4)
  1. Cost of IFX treatment between the two groups

    Comparing costs for treatment with IFX between the two groups

    Measured: 52 weeks

  2. Proportion of patients with antibodies against IFX

    Measured: 52 weeks

  3. Quality of life

    With a QoL questionnaire

    Measured: 52 weeks

  4. Biochemical disease activity (CRP >5mg/L and fecal calprotectin ≥50% compared to baseline, to a value of >250 ug/g)

    A rise in fecal calprotectin of ≥50% compared to baseline, to a value of >250 ug/g and/or serum CRP of >5mg/L

    Measured: 26 weeks, 52 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing PRECISION dosing Infliximab in people with Inflammatory Bowel Disease, run by Academisch Medisch Centrum - Universiteit van Amsterdam (AMC-UvA) at 1 site in Netherlands.

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 4 inclusion and 1 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: finished, as of the sponsor's last update on 6 Aug 2019. 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 Netherlands. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sustained clinical remission for the precision dosing group vs. the conventional IFX maintenance dosing group (time frame: 52 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02453776, which also lists 1 linked publication.

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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Aug 2019.
