An Open Label Phase 4 Study to Evaluate Efficacy of Early Versus Late Use of Vedolizumab in Ulcerative Colitis

Are you eligible to participate in this study?

You may be eligible for this study if you meet the following criteria:

  • Conditions: Ulcerative Colitis
  • Age: Between 18 - 80 Years
  • Gender: Male or Female

Inclusion Criteria:

  1. In the opinion of the investigator, the subject is capable of understanding and complying with protocol requirements.
  2. The subject signs and dates a written, informed consent form and any required privacy authorization prior to the initiation of any study procedures.
  3. Age 18 to 80
  4. Male or non-pregnant, non-lactating females. Females of child bearing potential must have a negative serum pregnancy test prior to randomization, and must use a hormonal (oral, implantable or injectable) or barrier method of birth control throughout the study. Females unable to bear children must have documentation of such in the source records (i.e., tubal ligation, hysterectomy, or post-menopausal [defined as a minimum of one year since the last menstrual period]).
  5. Established diagnosis of ulcerative colitis with histopathological confirmation available in the record of the patient.
  6. Moderate to severe active UC (total Mayo score > 6) with objective evidence of inflammation that can be visualized on endoscopy. All endoscopies will be video-taped for later review, rereading and quality assurance. Patients must have an endoscopic Mayo score of 2 or 3.
  7. Anti-TNF discontinued for at least 6 weeks
  8. Written informed consent must be obtained and documented


  1. Diagnosis of UC < 4 years prior to enrollment confirmed by clinical, endoscopic and histopathological evidence.
  2. Demonstrated failure to respond to aminosalicylates or intolerance to aminosalicylates and: failure to respond to topical or systemic corticosteroids or intolerance to corticosteroids or: need for > 1 course of steroids per year or: steroid dependency at any dose and additionally, but not mandatory, lack of efficacy of thiopurines or intolerance to thiopurines (azathioprine, 6-mercaptopurine or 6-thioguanine) (any duration). Patients who are using thiopurines at screening must have used them for > 3 months (last 4 weeks at stable dose).


  1. Diagnosis of UC confirmed by clinical, endoscopic and histopathological evidence.
  2. Demonstrated failure to respond to aminosalicylates or intolerance to aminosalicylates and: failure to respond to at least 3 months of thiopurines (TP) or intolerance to TP 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. Loss of response to anti-TNF is defined as recurrence of symptoms during maintenance dosing following prior clinical benefit.

May continue stable dose of conventional therapies for Inflammatory Bowel Disease ( IBD) including aminosalicylates and thiopurines and corticosteroids. Steroids will be tapered by protocol by week 14. Anti-TNF must be discontinued for > 6 weeks.

Exclusion Criteria:

  1. Prior treatment with vedolizumab.
  2. Contraindication for endoscopy.
  3. History of colonic dysplasia/cancer
  4. Extensive colonic resection, i.e. subtotal or total colectomy with <15 cm colon remaining
  5. Received other biologics within the last 4 weeks of baseline
  6. Use of 5-ASA or corticosteroid enemas/suppositories within 2 weeks of enrollment
  7. Chronic hepatitis B or C infection
  8. Evidence of or treatment for C. difficile infection or other intestinal pathogen at screening within 4 weeks prior to enrollment
  9. Active or latent tuberculosis
  10. Conditions which in the opinion of the investigator may interfere with the subject's ability to comply with the study procedures.
  11. Received any investigational drug in the past 30 days or 5 half-lives, whichever is longer.
  12. Positive progressive multifocal leukoencephalopathy (PML) subjective symptom checklist before enrollment
