E.1.2 Medical condition or disease under investigation |
E.1.2 | Version | 13.1 |
E.1.2 | Level | PT |
E.1.2 | Classification code | 10011401 |
E.1.2 | Term | Crohn's disease |

E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
1) 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.
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.
2) Total expenses related to Crohn's disease during the study (inclusion to week 12).
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. |
|
E.2.2 | Secondary objectives of the trial |
- Mean change compared to baseline in WPAI score at week 12.
- Mean change compared to baseline in IBDQ score at week 12.
- Mean change compared to baseline in CDAI score at week 4,8, 12,20.
- Mean change compared to baseline in PDAI score at week 4, 8, 12, and 20.
- Clinical response at week 4, 8, 20. Clinical response is defined as decrease of 70 in CDAI (luminal disease) or 50% reduction of active fistulas (fistulizing disease).
- Change in laboratory parameters (hemoglobin, crp, albumin) from inclusion to week 12.
- Total number of days with subjective feelinhg of disability due to Crohn's disease from inclusion to week 12.
- Total number of serious adverse drug reactions from inclusion to week 12.
- Expenses related to Crohn's diseae at week 20
- 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 |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal 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 criterias) .
3. Minimum 18 years.
4. Previous good response to at least 3 doses (5mg/kg) of infliximab (as judged by the treating physician).

E.4 | Principal exclusion criteria |
1. Any contraindication to continued infliximab treatment
2. Short bowel syndrome

4. Current or recent history of severe, progressive, and/or uncontrolled renal, hepatic, haematological, gastrointestinal, endocrine, pulmonary, cardiac, neurological, or cerebral disease.
5. Pregnancy
6. History of alcohol or drug abuse within the prior year
7. Patients who do not meet concomitant medication criteria
8. Any other condition, which in the Investigator’s juegment would make the patient unsuitable for inclusion in the study. |
