The 6-month safety and efficacy of abatacept in patients with rheumatoid arthritis who underwent a washout after anti-tumour necrosis factor therapy or were directly switched to abatacept: the ARRIVE trial.

ABSTRACT: To assess the safety, tolerability and efficacy of abatacept in patients with rheumatoid arthritis (RA) who had failed anti-tumour necrosis factor (TNF) therapy and were switched to abatacept directly or after completing washout.In this international, 6-month, open-label trial, patients had active RA, an inadequate response to anti-TNF therapy for 3 months or longer and a disease activity score in 28 joints (DAS28 (C-reactive protein; CRP) of 5.1 or greater. "Washout" patients discontinued anti-TNF therapy 2 months or longer pre-screening; "direct-switch" patients began abatacept ( approximately 10 mg/kg) at their next scheduled anti-TNF therapy dose.1046 patients were treated (449 washout, 597 direct-switch; baseline characteristics were similar between groups). At 6 months, adverse events (AE; 78.0% vs 79.2%), serious AE (11.1% vs 9.9%) and discontinuations due to AE (3.8% vs 4.0%) and serious AE (2.0% vs 1.3%) were comparable in washout versus direct-switch patients. There were no opportunistic infections. At 6 months, in washout versus direct-switch patients, similar clinically meaningful improvements were seen in DAS28 (CRP) (> or =1.2 unit improvement, 59.5% vs 53.6%, respectively; low disease activity state, 22.5% vs 22.3%; DAS28-defined remission, 12.0% vs 13.7%), physical function (health assessment questionnaire disability index > or =0.22 improvement; 46.3% vs 47.1%) and health-related quality of life (mean change in short-form 36 scores: physical component summary, 5.5 vs 6.1; mental component summary, 4.8 vs 5.4).Abatacept demonstrated acceptable safety and tolerability and clinically meaningful efficacy over 6 months in patients with inadequate response to anti-TNF therapy. Results were comparable with or without a washout, supporting direct switching from anti-TNF therapy to abatacept as an option in clinical practice.NCT00124982.

Project description:Rheumatoid arthritis (RA) is a chronic, inflammatory disease affecting synovial joints. Patients with persistent, active disease have traditionally been treated with disease-modifying antirheumatic drugs (DMARDs) (eg, methotrexate) or biologic agents (eg, tumor necrosis factor [TNF] antagonists). However, patients may discontinue these treatments due to toxicity, infection, or lack of efficacy. Two additional biologic therapies-rituximab and abatacept-are currently available for TNF-antagonist inadequate responders. Abatacept is also indicated for inadequate responders to traditional DMARDs.The aims of this review was to provide an overview of the issues surrounding the treatment of RA patients experiencing inadequate responses to current treatment and to discuss the current and future impact of abatacept on the RA treatment armamentarium.The MEDLINE, EMBASE, and BIOSIS databases were searched (search dates: January 1, 2000-September 19, 2007) using the terms abatacept or CTLA-4 or Orencia with rheumatoid arthritis. Full text articles in English were selected for relevance, and only articles presenting primary clinical trial data from randomized, placebo-controlled, clinical trials of abatacept were included. This review focused on the Phase III trials of abatacept in methotrexate and/or TNF-antagonist inadequate responders, as these trials had the largest number of patients and the longest study durations.The literature search initially yielded 848 papers. A total of 12 articles fulfilled the inclusion criteria. Abatacept is a novel agent that has been reported to reduce the signs and symptoms of RA in patients with active RA with an inadequate response to DMARDs and/or TNF-antagonist treatment. In both of these patient populations, treatment with abatacept was found to provide clinically meaningful health-related quality-of-life benefits, such as improvements in physical function, activity limitation, sleep, and fatigue. Abatacept was reported to have a consistent safety and tolerability profile, with a low rate (3.5%-4.2%) of discontinuation due to adverse events.The efficacy and tolerability data from Phase III clinical trials suggest that abatacept is an effective and generally well tolerated treatment option for RA patients with an inadequate response to methotrexate and/or TNF antagonists.
