Clinical Trial Summary

To assess the clinical efficacy and safety of certolizumab pegol as add-on therapy with stable-dose disease-modifying antirheumatic drugs (DMARDs) for achieving clinical remission in patients with moderate to low disease activity rheumatoid arthritis

Description:

Treatment period starts with a 24-week, double blind, placebo-controlled, randomized period followed by an open label phase until week 52.

In the double blind phase eligible patients will be randomized via an Interactive Voice Response System (IVRS) in a 1:1 ratio to receive either certolizumab pegol (400 mg at Weeks 0, 2 and 4, followed by 200 mg every two weeks) or placebo up to and including Week 22. All patients will continue to receive their Disease Modifying AntiRheumatic Drugs (DMARDs) therapy established before study entry until Week 52. At Week 24, patients will not receive any injection but will be evaluated:

• Non-remitters at Week 24 (patients who did not achieve remission at both Week 20 and Week 24) will be discontinued from the study and may be given the opportunity to enter in an open-label follow-up trial, C87080 [NCT00843778], with certolizumab pegol.

• Remitters (i.e. patients who achieved remission as measured by Clinical Disease Activity Index (CDAI) at both Week 20 and Week 24) will stop their randomized treatment (certolizumab pegol or placebo) and be followed up until Week 52. Remitters who flare up (CDAI ≥11 confirmed at two consecutive visits four weeks apart) between Week 24 and Week 52 will be re-treated with the same dosing regimen of certolizumab pegol (3 administrations of 400mg, given every 2 weeks, followed by 200 mg given every other week) up to and including Week 50.

Remitters who flare up between Week 24 and Week 52 and complete 52-week study period will be allowed to enter open label follow up trial at Week 52.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Clinical Disease Activity Index (CDAI) Remission (=2.8) at Both Week 20 and Week 24	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 (PtGADA-VAS in cm), and Physician's Global Assessment of Disease Activity - Visual Analog Scale (PhGADA-VAS in cm). 28 joints are examined where a lower score indicates less disease activity. Missing values were imputed using Non-Responder Imputation (NRI)	Week 20 and Week 24
Secondary	28-joint Count Disease Activity Score (DAS28-ESR) Remission (<2.6) at Both Week 20 and Week 24	DAS28-ESR is calculated using the tender joint count (TJC), swollen joint count (SJC) erythrocyte sedimentation rate (ESR in mm/hour), and the Patient's Global Assessment of Disease Activity - Visual Analog Scale (PtGADA-VAS in mm) using the following formula: 0.56 x v(TJC) + 0.28 x v(SJC) + 0.70 x lognat (ESR) + 0.014 x Patient Global Assessment of Arthritis where 28 joints are examined and a lower score indicates less disease activity. Missing values were imputed using Non-Responder Imputation (NRI)	Week 20 and Week 24
Secondary	Simplified Disease Activity Index (SDAI) Remission (=3.3) at Both Week 20 and Week 24	SDAI is calculated as the sum of tender joint count (TJC), swollen joint count (SJC), C-reactive protein (CRP in mg/dL), Patient's Global Assessment of Disease Activity - Visual Analog Scale (PtGADA-VAS in cm), and Physician's Global Assessment of Disease Activity - Visual Analog Scale (PhGADA-VAS in cm). 28 joints are examined where a lower score indicates less disease activity. Missing values were imputed using Non-Responder Imputation (NRI)	Week 20 and Week 24
Secondary	Time From Stopping Treatment (Week 24) to Loss of Remission (up to Week 52) Assessed Using Clinical Disease Activity Index (CDAI) Scores at 2 Consecutive Visits	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 (PtGADA-VAS in cm), and Physician's Global Assessment of Disease Activity - Visual Analog Scale (PhGADA-VAS in cm). 28 joints are examined where a lower score indicates less disease activity. Patients losing remission (CDAI >2.8) for two consecutive visits will be considered as having the event on the day of the visit where remission was first lost. Subjects discontinued/non-remitted by Week 24 are considered as having the event on day 1.	Week 24 up to Week 52
Secondary	Time From Stopping Treatment (Week 24) to Loss of Remission (up to Week 52) Assessed Using Simplified Disease Activity Index (SDAI) Scores at 2 Consecutive Visits	SDAI is calculated as the sum of tender joint count (TJC), swollen joint count (SJC), C-reactive protein (mg/dL), Patient's Global Assessment of Disease Activity - Visual Analog Scale (PtGADA-VAS in cm) and Physician's Global Assessment of Disease Activity (PhGADA-VAS in cm). 28 joints are examined. A lower score indicates less disease activity. Patients losing remission (SDAI >3.3) for two consecutive visits will be considered as having the event on the day of the visit where remission was first lost. Subjects discontinued/non-remitted by Week 24 are considered as having the event on day 1.	Week 24 up to Week 52
Secondary	Time From Stopping Treatment (Week 24) to Loss of Remission (up to Week 52) Assessed Using DAS28-ESR Scores at 2 Consecutive Visits	DAS28-ESR is calculated using tender joint count (TJC), swollen joint count (SJC), erythrocyte sedimentation rate (ESR mm/hour) and Patient's Global Assessment of Disease Activity - Visual Analog Scale (PtGADA-VAS mm). 0.56xv(TJC) + 0.28xv(SJC) + 0.70xlognat(ESR) + 0.014xPtGADA-VAS. 28 joints are examined. Lower score indicates less disease activity. Patients losing remission (DAS28-ESR=2.6) for two consecutive visits will be considered as having the event on the first of the two visits. Subjects discontinued/non-remitted by Week 24 are considered as having the event on day 1.	Week 24 up to Week 52
Secondary	American College of Rheumatology 20% (ACR20) Response at Week 24	ACR20 responders are subjects with at least 20% improvement from Baseline for tender joint count (TJC), swollen joint count (SJC), and at least 3 of the 5 remaining core set measures: 1) Health Assessment Questionnaire-Disability Index (HAQ-DI), 2) C-reactive Protein (CRP), 3) Patient's Assessment of Arthritis Pain-Visual Analog Scale, 4) Patient's Global Assessment of Disease Activity-Visual Analog Scale, 5) Physician's Global Assessment of Disease Activity-Visual Analog Scale.

Missing values were imputed using Non-Responder Imputation (NRI)	Baseline, Week 24
Secondary	Change From Baseline in Health Assessment Questionnaire Disability Index (HAQ-DI) at Week 24	HAQ-DI is derived based on the mean of individual scores in 8 categories of daily living actives (using 20 questions). Each question is scored 0-3 (0 = without any difficulty, 1 = with some difficulty, 2 = with much difficulty, and 3 = unable to do). Change from Baseline is computed as the value at Week 24 minus the Baseline value. A negative value in change from Baseline indicates an improvement.
