  Purpose

To compare treatment outcome in patients with Crohn's disease with secondary loss of response to infliximab (i.e. initial good response follow by loss of response) treated according to current standards based only on clinical features versus treatment based on serum levels of infliximab and anti-infliximab antibody (Ab) status.

Primary Outcome Measures:
  • Proportion of patients with response at week 12, i.e. CDAI decrease of 70 or more for patients with luminal disease, or reduction of 50 percent or more from base line in the number of draining fistulas for patients with fistulising disease. [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]

    Clinical response rates at week 12 should be non-inferior in the intervention group as compared to the control group.

    Both primary end-points should be met in order to declare the primary end-points succesfully archived.


  • Total expenses related to Crohn's disease during the study (inclusion to week 12). [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]

    Crohn related expenses at week 12 should be less in the intervention group as compared to the control group.

    Both primary end-points should be met in order to declare the primary end-points succesfully archived.



Secondary Outcome Measures:
  • Mean change compared to baseline in WPAI score at week 12. [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Mean change compared to baseline in IBDQ score at week 12. [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Mean change compared to baseline in CDAI score at week 4,8, 12,20. [ Time Frame: 4, 8, 12, 20 weeks ] [ Designated as safety issue: No ]
  • Mean change compared to baseline in PDAI score at week 4, 8, 12, and 20. [ Time Frame: 4, 8, 12, 20 weeks ] [ Designated as safety issue: No ]
  • Clinical response at week 4, 8, 20 [ Time Frame: Week 4, 8, 20 ] [ Designated as safety issue: No ]
    Clinical response is defined as decrease of 70 in CDAI (luminal disease) or 50% reduction of active fistulas (fistulizing disease).

  • Laboratory parameters [ Time Frame: Week 12 ] [ Designated as safety issue: No ]
    Change in laboratory parameters (hemoglobin, crp, albumin) from inclusion to week 12.

  • Days with subjective feeling of disability due to Crohn's disease [ Time Frame: week 12 ] [ Designated as safety issue: No ]
    Total number of days with subjective feelinhg of disability due to Crohn's disease from inclusion to week 12.

  • Serious adverse drug reactions [ Time Frame: week 12 ] [ Designated as safety issue: Yes ]
    Total number of serious adverse drug reactions from inclusion to week 12.

  • Expenses related to Crohn's diseae at week 20 [ Time Frame: week 20 ] [ Designated as safety issue: No ]
  • Expenses related to Crohn's disease compared to change in CDAI-score (luminal disease) or PDAI-score (fistulizing disease), and IBD-score at week 12 and 20 [ Time Frame: week 12 and 20 ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Active Comparator: 1
Patients with Crohn's disease with secondary loss of response to infliximab.
Procedure: Measurement of serum infliximab and anti-infliximab antibodies

In the intervention group treatment of patients with Crohn's disease with secondary loss of response to infliximab is based on serum infliximab and anti-infliximab Ab levels according to following algorithm:

  1. Low s-infliximab in the presence of anti-infliximab Ab: Adalimumab 80 mg s.c. followed by 40 mg every 2 weeks.
  2. Low s-infliximab without anti-infliximab Ab: Infliximab 10 mg/kg i.v. every 8 weeks.
  3. High s-infliximab without anti-infliximab Ab: Stop infliximab treatment. Review history. Steroids or surgery.
  4. High s-infliximab in the presence of anti-infliximab Ab: Same as number 3.
Active Comparator: 2
Patients with Crohn's disease with secondary loss of response to infliximab.
Procedure: Treatment according to current standards without knowledge of serum infliximab and anti-infliximab Ab status
In the control group patients with Crohn's disease with secondary loss of response to infliximab is treated according to current standard of care which is to increase dose of infliximab to 5 mg/kg every 4 weeks without knowledge of serum infliximab levels and anti-infliximab Ab status.

  Eligibility

Ages Eligible for Study:   18 Years and older

Criteria

Inclusion Criteria:

  1. Patient must be able to understand the information given to him/her and give written informed consent.
  2. Definitive diagnosis of Crohn's disease (confirmed by recent radiological, endoscopic and/or histological evidence according to international criteria) .
  3. Age minimum 18 years.
  4. Previous good response to at least 3 doses (5mg/kg) of infliximab (as judged by the treating physician).
  5. Loss of response to standard doses of infliximab (as judged by the treating physician).
  6. Last infliximab infusion given at least 4 weeks before inclusion.
  7. For patients with luminal disease, the CDAI should be above 220 points at inclusion.
