May 29, 2014 updated by: Michael Schiff, MD

Can TNF-Alpha Incomplete Secondary Responders Attain a Safe and Efficacious Response By Switching to Certolizumab Pegol (Cimzia)? A Phase IV, Randomized, Multi-Center, Double-Blind, Twelve-Week Study Followed by a 12-Week Open-Label Phase

Purpose of the study is to determine if Cimzia is safe and effective in subjects who have received previous treatment with a TNF-alpha inhibitor other than Cimzia.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a Phase IV, randomized, multi-center, double-blind, parallel-group 12-week study of Cimzia with concomitant methotrexate (MTX) or other DMARD compared to MTX or other DMARD alone in patients with an inadequate secondary therapeutic response to a TNF-alpha inhibitor as defined above and active rheumatoid arthritis (RA) followed by a 12-week open-label phase with concomitant MTX or other DMARD and Cimzia.

Subjects must washout from the previous TNF inhibitor for at least 4 weeks prior to the baseline visit. Subjects unable to tolerate MTX must have been on a stable dose of another non-biologic DMARD for at least 3 months. Subjects' diagnosis of RA must be based on the 1987 Revised American Rheumatism Association Criteria for the Classification of Rheumatoid Arthritis.

Subjects will be screened for eligibility and, up to 28 days later, at the baseline visit, randomized to one of two treatment groups (2:1): Cimzia or placebo (in addition to concomitant MTX or other DMARD). All subjects will continue MTX/other DMARD at the same dose utilized prior to study entry.

After the Week 12 study visit, all subjects will have the opportunity to continue in the study on open-label Cimzia treatment (using an induction regimen for all subjects, regardless of their treatment in the blinded phase).

Time Frame: From Baseline to Week 12

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 (VAS), 4) Patient's Global Assessment of Disease Activity-Visual Analog Scale (VAS), 5) Physician's Global Assessment of Disease Activity-Visual Analog Scale(VAS).

HAQ-DI: participant-reported assessment of ability to perform tasks in 8 categories of daily living activities: dress/groom; arise; eat; walk; reach; grip; hygiene; common activities over past week. Each item scored on 4-point scale from 0-3: 0=no difficulty; 1=some difficulty; 2=much difficulty; 3=unable to do.

A lower score indicated less disease activity.

Baseline to Week 12
Proportion of Subjects Achieving a EULAR Good or Moderate Response Criteria in the Cimzia Treatment Group Compared to the Placebo Group
Time Frame: Baseline to week 12

The EULAR (European League Against Rheumatism) response criteria is a classified response criteria which classifies the patients individual as non-, moderate or good responders dependent on the change and the level of the Disease Activity Score.

The Disease Activity Score(DAS28) is a continuous disease measure composite of 4 variables: 28 tender joint count, 28 swollen joint count, ESR or CRP, and participant assessment of disease activity measure on a visual analogue scale. High disease activity= > 5.1, low disease activity= < 3.2, and remission= < 2.6. Clinically significant response= decrease of >1.2 from baseline. Utilizing EULAR response criteria, DAS28 categorical responses define a good (absolute: <3.2 or >1.2 improvement from baseline), moderate (absolute: 3.2-5.1 or 0.6-1.2 change from baseline), or no response (absolute: >5.1 or <0.6 change from baseline).
