Trial Outcomes & Findings for Maintenance Study of Certolizumab Pegol (CZP) in Crohn's Disease (NCT NCT00329550)

Results Overview

CDAI responders are subjects achieving either clinical response (a reduction in CDAI score of ≥100 points from Week 0), or remission (CDAI ≤150). CDAI is used to quantify the symptoms of subjects with Crohn's disease. A score of 150 or below indicates remission and a score above 450 indicates extremely severe disease.

Participant Flow

Recruitment into this extension study was between March 2006 and April 2008. Of the 26 hospitals and medical centers throughout Japan in the main study, 16 sites went on to enter subjects in this extension study.

To enter this single-group extension study, C87047 (NCT00329550), subjects had to have responded at Week 6 of the double-blind main study, C87037 (NCT00291668). Recruitment details are provided for the 40 subjects who entered this extension study by the three possible treatment sequences received across both studies.

PRIMARY outcome

Timeframe: Week 0 and Week 26 (relative to the start of the 6-week double-blind main study (NCT00291668)). 'Week 26' is 18 weeks after the first visit in this extension study.

Population: Responders at Week 6 of double-blind main study, C87037 (NCT00291668) could enter this open-label extension study, C87047 (NCT00329550). All 39 subjects in the Full Analysis Set (FAS) were included in this summary. If a subject withdrew or received rescue therapy, they were counted as a non-responder in that study from that time-point onwards.

CDAI responders are subjects achieving either clinical response (a reduction in CDAI score of ≥100 points from Week 0), or remission (CDAI ≤150). CDAI is used to quantify the symptoms of subjects with Crohn's disease. A score of 150 or below indicates remission and a score above 450 indicates extremely severe disease.

SECONDARY outcome

Timeframe: Week 0 and Week 8 (relative to the start of the 6-week double-blind main study (NCT00291668)). 'Week 8' is the first visit in this extension study.

Population: Responders at Week 6 of double-blind main study, C87037 (NCT00291668) could enter this open-label extension study, C87047 (NCT00329550). Subjects in the Full Analysis Set (FAS) with data at both time-points are included. Data collected after receipt of rescue therapy have been set to missing in that study. \[Week 8 is the start of Study C87047\].

CDAI is used to quantify the symptoms of subjects with Crohn's disease. A score of 150 or below indicates remission and a score above 450 indicates extremely severe disease. A decrease in CDAI over time indicates improvement in disease activity.

Population: Responders at Week 6 of double-blind main study, C87037 (NCT00291668) could enter this open-label extension study, C87047 (NCT00329550). All 39 subjects in the Full Analysis Set (FAS) were included in this summary. If a subject withdrew or received rescue therapy, they were counted as a non-responder in that study from that time-point onwards.

CDAI responders are subjects achieving either clinical response (a reduction in CDAI score of ≥100 points from Week 0), or remission (CDAI ≤150). CDAI is used to quantify the symptoms of subjects with Crohn's disease. A score of 150 or below indicates remission and a score above 450 indicates extremely severe disease.

Please see post-hoc outcome measure 80 where the number of subjects with disease progression is presented.

Time to disease progression is defined as the earliest of: * time to an increase from Week 6 of ≥100 points in Crohn's Disease Activity Index (CDAI) score and CDAI \>175 points for at least 2 consecutive visits, * time to use of rescue therapy, or, * time to subject withdrawal from the study.

SECONDARY outcome

Timeframe: Week 0 and Week 26 (relative to the start of the 6-week double-blind main study (NCT00291668)). 'Week 26' is 18 weeks after the first visit in this extension study.

Population: Responders at Week 6 of double-blind main study, C87037 (NCT00291668) could enter this open-label extension study, C87047 (NCT00329550). Subjects in the Full Analysis Set (FAS) with data at both time-points are included. Data collected after receipt of rescue therapy in a study have been set to missing in that study.

The IBDQ Social Domain Sub-Score is the sum of 8 responses, each ranging from 0 to 7, thus the Sub-Score ranges from 0 to 56; a higher score indicating a better quality of life.

POST_HOC outcome

Timeframe: Week 6 to Week 26 (relative to the start of the 6-week double-blind main study (NCT00291668)). 'Week 6' is the last visit in the double-blind main study and 'Week 26' is 18 weeks after the first visit in this extension study.

Population: Responders at Week 6 of Study C87037 (NCT00291668) could enter this extension study, C87047 (NCT00329550). As it was not possible to calculate the time to disease progression (outcome measure 22) due to the very small number of subjects meeting this definition, the post-hoc outcome of number of subjects with disease progression is presented here.

Disease progression is defined as: * an increase from Week 6 of ≥100 points in Crohn's Disease Activity Index (CDAI) score and CDAI \>175 points for at least 2 consecutive visits, * use of rescue therapy, or, * subject withdrawal from the study.
