Corticosteroid Sparing Effect of Certolizumab in Crohn's Disease

Phase 3

Terminated

• Conditions: Crohn's Disease

• Registration Number: NCT00349752
• Lead Sponsor: UCB Pharma

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.

Primary Outcome Measures

Name	Time	Method
Percentage of Subjects Who Have Been Withdrawn From Prednisone or Prednisolone Therapy According to the Corticosteroid Tapering Schedule and Have Remained Off Corticosteroids and in Disease Remission at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	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.

Secondary Outcome Measures

Name	Time	Method
Percentage of Subjects With Continuous Remission Off Steroids at Week 38	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. A subject with continuous remission off steroids at Week 38 is a subject in remission (CDAI =\< 150) from the visit when he stops taking steroids to Week 38 and is off corticosteroids until Week 38.
Per-subject Median Weekly Dose of Corticosteroids Over the 38-week Double-blind Treatment Period	Over the 38-week double-blind treatment period	The median weekly dose of corticosteroids is calculated for each subject, and these per-subject median values are further summarized by treatment group. The mean of the per-subject median doses in each treatment group is presented here.
Change From the 6-week run-in Period in Per-subject Median Weekly Dose of Corticosteroids Over the 38-week Double-blind Treatment Period	6-week run-in period, 38-week double-blind treatment period	The run in period lasted a minimum of 1 week and a maximum of 6 weeks. During this period subjects were treated with any dose or type of systemic corticosteroids the Investigator felt was appropriate. To be eligible for study randomization, subjects must have been in remission (CDAI ≤150 points) and receiving corticosteroids at a dose no higher than 30 mg/day prednisone or equivalent during the week prior to randomization. Subjects who did not meet these criteria were not randomized and were withdrawn from the study.
Cumulative Percentage of Subjects With Relapse/Treatment Failure at Week 38	Week 38	A subject with relapse/ treatment failure has a Crohn's Disease Activity Index (CDAI) \> 150 and an increase in CDAI of \>= 70 points versus Week 0. \[The CDAI is used to quantify the symptoms of subjects with Crohn's disease. A score of 150 or below indicates disease remission and a score above 450 indicates extremely severe disease.\]
Per-subject Cumulative Dose of Corticosteroids Over the 48-week Study Period	Over the 48-week study period	The cumulative dose of corticosteroids over the 48-week study period is calculated for each subject individually. The mean of these values for each treatment group is presented here.
Inflammatory Bowel Disease Questionnaire (IBDQ) Total Score at Week 38	Week 38	The total IBDQ score will be derived as the sum of the responses (each ranging from 1 to 7) to all 32 questions on the IBDQ and can therefore range from 32 to 224. A higher score indicates a better quality of life. IBDQ remission is defined as a subject having an IBDQ total score \>= 170 points.
Change From Baseline in CDAI Score at Week 38	Week 0, Week 38	The Crohn's Disease Activity Index (CDAI) is used to quantify the symptoms of subjects with Crohn's disease. A score of 150 or below indicates disease remission and a score above 450 indicates extremely severe disease. A decrease in CDAI over time indicates improvement in disease activity.
Crohn's Disease Activity Index (CDAI) Score at Week 38	Week 38	The Crohn's Disease Activity Index (CDAI) is used to quantify the symptoms of subjects with Crohn's disease. A score of 150 or below indicates disease remission and a score above 450 indicates extremely severe disease. A decrease in CDAI over time indicates improvement in disease activity.
Time to Relapse/Treatment Failure During the 38-week Double-blind Treatment Period	During the 38-week double-blind treatment period	A subject with relapse/ treatment failure has a Crohn's Disease Activity Index (CDAI) \> 150 and an increase in CDAI of \>= 70 points versus Week 0. \[The CDAI is used to quantify the symptoms of subjects with Crohn's disease. A score of 150 or below indicates disease remission and a score above 450 indicates extremely severe disease.\]
Change From Baseline in Inflammatory Bowel Disease Questionnaire (IBDQ) Total Score at Week 38	Week 0, Week 38	The total IBDQ score will be derived as the sum of the responses (each ranging from 1 to 7) to all 32 questions on the IBDQ and can therefore range from 32 to 224. A higher scores indicates a better quality of life. IBDQ response is defined as an increase from baseline in the IBDQ total score \>= 16 points.
