Brief summary
The current study is designed to measure the corticosteroid-sparing effect of certolizumab pegol using a defined schedule of corticosteroid tapering in subjects with moderate to severe Crohn's disease. Subjects had to be in remission (CDAI\<=150) and receiving corticosteroids at a dose no higher than 30 mg/day prednisone or equivalent during the week prior to randomization.
Interventions
Certolizumab pegol 400 mg provided in solution for subcutaneous injection (2 x 200 mg/mL) in single-use vials for administration at Weeks 0, 2, 4 and then every 4 weeks until Week 36. Two vials will be required for each dosing.
Placebo (commercially available sodium chloride 0.9% (preservative free)) provided for subcutaneous injection in single-use vials for administration at Weeks 0, 2, 4 and then every 4 weeks until Week 36. Two vials will be required for each dosing.

Outcome results
Percentage of Subjects Who Have Been Withdrawn From Prednisone or Prednisolone Therapy According to the Corticosteroid Tapering Schedule and Have Remained Off Corticosteroids and in Disease Remission at Week 38
The Crohn's Disease Activity Index (CDAI) is used to quantify the symptoms of subjects with Crohn's disease. A CDAI score of 150 or below indicates disease remission and a score above 450 indicates extremely severe disease.
Time frame: Week 38
Population: Intention-to-treat (ITT) population which consists of all randomized subjects who received at least one injection of study medication. In the analyses of remission rates, subjects for whom it is impossible to assess the remission status will be conservatively considered as non-remitters in the calculations.
