E.1.1.2 | Therapeutic area | Diseases [C] - Digestive System Diseases [C06] |
MedDRA Classification |
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 |
The primary objective of this prospective open label study is to assess the ability of vedolizumab to promote clinical, endoscopic and histological remission in patients with active Crohn's disease in an 'early' and a 'late' disease population after 54 weeks of treatment. |
|
E.2.2 | Secondary objectives of the trial |
Measures of clinical disease activity (including clinical response and remission) over the 1 year study period will be described. The mucosal healing capacity of vedolizumab treatment will be observed by assessing the endoscopic and histopathologic response to treatment over the 1 year study period. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Established diagnosis of ileal, ileocolonic or colonic Crohn’s disease with histopathological confirmation available in the record of the patient.
- Moderately to severely active CD (CDAI 220-450) with objective evidence of ulcerations visualized on endoscopy.
- Anti-TNF discontinued for at least 6 weeks
-Age 18 to 80
- GROUP 1 (EARLY CD):
Diagnosis of CD < 24 months prior to enrollment
Demonstrated failure to respond to topical or systemic corticosteroids or intolerance to corticosteroids
or: need for > 2 courses of steroids since diagnosis
or: steroid dependency at any dose since diagnosis
GROUP 2 (LATE CD)
Demonstrated failure to respond to at least 3 months of thiopurines or intolerance to thiopurines and: failure to respond to at least 1 anti-TNF or intolerance to anti-TNF or loss of response to at least 1 anti-TNF.

- Received any investigational drug in the past 30 days or 5 half-lives, whichever is longer.
- Positive PML subjective symptom checklist before enrollment.
- Subjects with known allergy or hyposensitivity to vedolizumab or its components
