  2. Documented diagnosis of ileal, ileocolonic, or colonic CD with a minimum disease duration of 3 months, as determined by endoscopic and histopathology assessment.
  3. Endoscopic confirmation of active disease with total SES CD total score of at least 7. For isolated ileal disease, SES CD total score should be at least 4.
  4. An average daily liquid/soft stool frequency (SF) greater than or equal to 2.5 or daily abdominal pain (AP) greater than or equal to 2.0.

  6. Subjects currently receiving the following treatment for CD are eligible providing they have been on stable doses as described below:

    • Oral corticosteroids (prednisone or equivalent up to 25 mg/day; budesonide up to 9 mg/day). Stable dose for at least 2 weeks prior to baseline. If oral corticosteroids have been recently discontinued, they must have been stopped at least 2 weeks prior to baseline. Decreases in steroid use due to AEs are allowed.
