Cimzia Treatment in Rheumatoid Arthritis: Randomizing to Stop Versus Continue Disease-modifying Anti-rheumatic Drug(s)
Recruitment status was: Recruiting
The purpose of this study is to investigate the safety and efficacy of Cimzia given as an add-on to your current therapy with disease-modifying anti-rheumatic drug(s) (DMARDs)including MTX or given as monotherapy (alone) over an 18 month period.
Approximately 125 patients with moderate to severe Rheumatoid Arthritis (RA) who are being prescribed Cimzia will be enrolled into the study.
|Study Design:||Observational Model: Cohort
Time Perspective: Prospective
|Official Title:||A Canadian Randomized Controlled Trial of DMARD Withdrawal in RA Patients Achieving Therapeutic Response With Cimzia + DMARD Combination Treatment.|
- The percentage of patients achieving DAS28<3.2 or maintaining a change in DAS from baseline of ≥ 1.2 at 18 months. [ Time Frame: At 18 months ] [ Designated as safety issue: No ]Between-group differences with respect to the proportion of subjects achieving DAS28<3.2 will be assessed for statistical significance with the Chi-square test. Multiple-logistic regression model with terms for treatment group and potential confounders will be used to produce adjusted estimates of the relative rate of achieving therapeutic effectiveness. Time to achieving DAS28<3.2 will be assessed with Kaplan Meier survival analysis.
- Mean change from baseline in DAS28 score in each group at 18 months [ Time Frame: At 18 months ] [ Designated as safety issue: No ]Between-group differences will be assessed for statistical significance with One Way ANOVA. General Linear Models will be used to adjust the between-group differences for potential confounders identified during the assessment of the baseline and demographic characteristics.

3 months: Discontinue vs continue DMARDS
At 3 months those patients who achieved a change in DAS28 of 1.2 or greater will be randomized to discontinue versus continue DMARDs and will be followed for an additional 15 months
6 months: discontinue vs continue DMARDs
(Protocol amendment 4.0)At 6 months, those patients still on Cimzia and DMARD therapy who were not randomized at month 3 AND achieve a change in DAS28> 1.2 will be randomized to discontinue versus continue DMARDs and will be followed for an additional 12 months.
6 months: D/C vs Cont'd DMARDs if change in DAS28
(Protocol amendment 4.0)At 6 months, if the change in DAS28 is at least 0.6 and there is a decision to continue Cimzia, then the patients will be randomized to discontinue versus continue DMARDs with Cimzia and will be followed for an additional 12 months.
3 or 6 months: stop CIMZIA and treat as per SOC
(Protocol amendment 4.0)If a change in DAS28 of <0.6 occurs at 6 months (at 3 months for protocol amendment 6.1)in patients not randomized at month 3 then the patient will stop Cimzia and treatment will be standard of care. However, patient will still be followed until the end of study.
Rheumatoid arthritis is a chronic systemic inflammatory disease that is associated with significant morbidity and mortality. The disease is characterized by inflammation of synovial joints that can result in pain, swelling and joint damage with secondary deformity and progressive disability and impairment of patient's health related quality of life. It is estimated that about 1% of the population worldwide has RA.
Treatment for RA includes use of nonsteroidal anti-inflammatory drugs (NSAIDs), cyclooxygenase-2 (COX-2) selective inhibitors, corticosteroids and DMARDs. The effectiveness and toxicities associated with use of DMARDs differs based on the individual agent; DMARDs are often partially effective. For those in whom DMARDs have not fully treated RA, TNF inhibitors are often prescribed.
TNFα plays an important role in RA. Activities ascribed to TNFα in RA include recruitment and activation of polymorphonuclear leukocytes (PMNs), cellular proliferation, increased prostaglandin and matrix-degrading protease activity, and bone and cartilage resorption.
CIMZIA (certolizumab pegol) in combination with methotrexate (MTX) is indicated for:
• reducing signs and symptoms, inducing major clinical response, and reducing the progression of joint damage as assessed by X-ray, in adult patients with moderately to severely active rheumatoid arthritis (RA).
