Description

Summary

Rheumatoid arthritis patients are at increased risk of cardiovascular disease because of systemic inflammation that can persist even in patients with well-controlled joint disease. We hypothesize that adding an anti-tumor necrosis factor medication, adalimumab, to standard non-biologic therapy for rheumatoid arthritis will improve endothelial function (reduce cardiovascular risk) in these patients. The design of the trial is as follows: 18 month prospective, randomized, double-blind crossover trial comparing the addition of adalimumab to the addition of placebo. The primary endpoint is a change in endothelial cell function, as detected by brachial artery FMD, at 6 months of adalimumab treatment compared to 6 months of placebo.

Official Title

Adalimumab to Mitigate Cardiovascular Risk in RA Patients With Well-Controlled Joint Disease

Details

Excess mortality associated with RA is due largely to CVD that is not explained by traditional risk factors. Although articular manifestations usually dominate the clinical picture, RA is a systemic inflammatory disease, and systemic inflammation is the thought to be the underlying mechanism responsible for the increased CVD risk associated with RA. Because chronic inflammation can persist in treated RA patients with little or no clinically detectable joint inflammation, treatment to targets based largely on clinically measured joint activity may not adequately suppress the systemic inflammation associated with progression of atherosclerosis. The ACR recommends treatment to a therapeutic target of low disease activity as determined by standardized clinical assessments. We hypothesize that treated RA patients who have reached this ACR target of low disease activity nonetheless have persisting systemic inflammation that contributes to atherogenesis. We further hypothesize that acceleration of RA-directed therapy with systemic anti-inflammatory treatments (TNF inhibition) in patients with low disease activity will improve endothelial function, reduce vascular inflammation and improve the functionality of HDL particles, key biological features in the progression of atherosclerosis and its clinical manifestations.

Trial design: Prospective, randomized, double-blind crossover trial comparing the addition of adalimumab to the addition of placebo.

Study population: 60 RA patients on non-biological DMARDs with low disease activity as determined by a standardized clinical assessment (Disease Activity Score 28 joints [DAS28] < 3.2).

Primary endpoint: Primary endpoint is change in endothelial cell function, as detected by brachial artery FMD, at 6 months of adalimumab treatment compared to 6 months of placebo. We postulate that anti-TNF therapy with adalimumab will lead to an absolute increase of 2% in FMD, which typically translates into a 15% reduction in cardiovascular event rates.
