Brief summary

During the run-in period, CZP will be administered at 400 mg (2 injections) at Wks 0, 2, and 4 and 200 mg with placebo (1 injection placebo, 1 injection CZP) at Wks 6, 8, 10, 12, 14 and 16. At Wk 18 patients will be grouped as responders or non-responders based on results of the ACR20 at Week 16.

Detailed description

Subjects with a stable methotrexate (MTX) dose enter the run-in period in which certolizumab pegol (CZP) will be administered at a dose of 400 mg (2 injections) at Weeks 0, 2, and 4 and at a dose of 200 mg with placebo (1 injection placebo, 1 injection CZP) at Weeks 6, 8, 10, 12, 14 and 16. The dose of MTX should be stable for at least 2 months prior to the Baseline visit and will remain stable throughout the trial, unless there is a need to reduce the dose for reasons of toxicity. At the Week 18 visit, subjects who were ACR20 (American College of Rheumatology 20% Improvement) responders at Week 16 will be randomized in a double-blinded way to receive either 400 mg CZP given every 4 weeks and placebo given every 4 weeks given as two injections (alternating CZP and placebo every two weeks) plus MTX, 200 mg CZP and placebo administered every 2 weeks (one injection of each) plus MTX, or Placebo administered as two injections every 2 weeks plus MTX. Non-responders will be withdrawn from the study.

MeasureTime frameDescription
Change From Baseline in PCS (Short Form 36-item Health Survey Physical Component Summary) at Week 34 in Patients Randomized at Week 18Baseline, Week 34PCS norm-based scores are calculated based upon the following 8 domain scores, Physical Functioning, Role Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role Emotional and Mental Health, and range from 1 to 81, where 50 represents the normative value. A larger positive value in change from Baseline indicates an improvement. This analysis was carried out using an ANCOVA model on Last Observation Carried Forward (LOCF) data with factors treatment and Baseline score.

CDAI (Clinical Disease Activity Index) Remission (CDAI ≤2.8) at Week 16 in All Patients

CDAI is calculated as the sum of tender joint count (TJC), swollen joint count (SJC), Patient's Global Assessment of Disease Activity - Visual Analog Scale (VAS in cm), and Investigator's Global Assessment of Disease Activity - Visual Analog Scale (VAS in cm). 28 joints are examined where a lower score indicates less disease activity. Missing values were imputed using Non-Responder Imputation (NRI). The range for the CDAI is 0 - 76 with a lower CDAI score indicating approvement in activity and a higher score indicating a decline activity.

Time frame: Week 16

Population: Since Non-Response Imputation (NRI) was used, all 333 subjects in the run-in period are included in this analysis
