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.

TB.

1. >9 mg/day of oral budesonide or >25 mg/day of prednisone or equivalent oral
systemic corticosteroid dose within 2 weeks prior to baseline.

2. IV, IM (parenteral), or topical (rectal) treatment of 5 ASA or corticosteroid
enemas/suppositories within 2 weeks prior to baseline.

agents within 1 year prior to baseline.

10. Subjects previously receiving leukocyte apheresis, including selective
lymphocyte, monocyte, or granulocyte apheresis, or plasma exchange within 6
months prior to baseline.
