Inclusion criteria
Inclusion criteria: 1. Patients =18 years and =65 years 2. Diagnosis of CD, based on endoscopy and histopathologic examination of mucosal biopsies 3. Written informed consent 4. Active mucosal disease as defined by a repeated faecal calprotectine = 250 µg/g at 2 consecutive occasions (=2 weeks and =3 months interval) AND presence of mucosal lesions as defined by a SES-CD > 6 (= 4 for L1 (ileal) disease) on screening ileocolonoscopy 5. On anti-TNF therapy (ADM at a dose of 40mg Subcutaneous (SC) every week (QW) or every other week (Q2W) and IFX at a dose of 5-10 mg/kg every 4-8 weeks) for a period of at least 4 months at stable dose. 6. Therapeutic trough serum concentrations of anti-TNF at screening (for IFX = 3 µg/ml and for adalimumab (ADM) = 5 µg/ml and undetectable levels of anti-drug antibodies (ADA’s) at baseline.

Exclusion criteria
Exclusion criteria: 1. Ulcerative colitis or indeterminate colitis 2. Current malignancy 3. Women: current pregnancy wish, pregnancy or lactation. Men: active child wish 4. Ongoing use of an immunomodulator (including azathioprine, methotrexate, 6-thioguanine, 6 mercaptopurine or mycophenolic acid). 5. Prior failure on anti-TNF and immunomodulator combination therapy due to refractory disease per treating physicians opinion. 6. Elevated liver enzymes (ALAT, ASAT, LDH, ?-GT, AF) >1.5 times the upper limit of normal (ULN) 7. Current use of any CYP3A4 inducing or inhibiting agents 8. Patients on prednisone >10mg/day or budesonide >6mg/day 9. Patients who require rescue therapy with corticosteroids during the screening phase 10.

Other conditions which in the opinion of the investigator may interfere with the subject’s ability to comply with the study procedure
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: In the current project the main objective is to evaluate the efficacy and safety of the addition of albendazole to anti-TNF monotherapy (=4 months) in adult patients with Crohn’s disease with incomplete mucosal healing.;Secondary Objective: Secondary objective is to conduct a cost-effectiveness and cost-utility analysis and a budget impact analysis of anti-TNF and albendazol combination therapy.;Primary end point(s): 1. Proportion of patients with absence of ulcers on centrally read endoscopies after 12 weeks of albendazole and anti-TNF combination treatment compared to placebo;Timepoint(s) of evaluation of this end point: At week 12 | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): 1. Proportion of patients with endoscopic response on centrally read endoscopies defined as a reduction in the Simple Endoscopic Severity index (SES-CD) score by = 50% compared to baseline 2. Proportion of patients with endoscopic remission on centrally read endoscopies defined as a SES-CD score < 3 in general or < 2 in case of L1 (ileal) disease 3. Costs per Quality Adjusted Life year (QALY) 4. Clinical endpoints: 4.1. Change in CDAI from baseline to W12 4.1.1. Clinical remission: CDAI < 150 4.1.2. Clinical (partial) response: decrease in CDAI = 70 points [CR-70]) 4.2. General and change in quality of life, as measured by the IBDQ, SF-36 and EQ-5D-5L at baseline, week 12 and 36 4.3. Patient Reported Outcome Measure (PROM): assessment of the general and change in functional status and well-being measured from the patients’ perspective by the IBD-CONTROL questionnaire [25], at baseline, week 12 and 36 4.4. Occurrence of (serious) adverse events (SAE) 5. Change in Anti-TNF serum concentration and anti-drug-antibodies from baseline to W12 6. Proportion of patients with hs-CRP < 5mg/L at W12 7. Proportion of patients with fecal calprotectin < 250 µg/g at W12 8. Proportion of patients with fecal calprotectin <100 µg/g at W12 9. Histological changes from baseline to W12 based on centrally read scanned biopsies using the colonic and ileal global histologic disease activity scoring system (CGHAS/IGHAS, appendix 14.2) and the Robarts histology index (RHI, appendix 14.3). 10. Presence of type 2 regulatory wound-healing macrophages (CD14+CD68+CD206+) by immunohistochemical staining and fluorescence-activated cell sorting on intestinal biopsies ;Timepoint(s) of evaluation of this end point: Different timepoints during the 9 months duration of the trial (Week 0, 2, 4, 8, 12 and 36) | — |
