  Eligibility

Ages Eligible for Study:   18 Years to 70 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • A positive histological diagnosis of UC ≥3 months prior to entry into the study. If a histological diagnosis is not available but all signs and symptoms suggest UC, the subject's eligibility should be discussed with Pfizer.
  • Active UC as defined by a score of ≥6 on the Mayo score.
  • An endoscopic (by flexible sigmoidoscopy) sub-score of ≥2 on the Mayo score determined within 7 days of first dosing.

Exclusion Criteria:

  • Subjects with UC, which is confined to a proctitis on a flexible sigmoidoscopy.
  • Subjects who have had surgery as a treatment for UC or are likely to require surgery within the duration of the study.
  • Subjects displaying clinical signs of ischemic colitis.
