BACKGROUND Remission and radiographic non-progression are goals in the treatment of early rheumatoid arthritis. The aim of the combination of methotrexate and etanercept in active early rheumatoid arthritis (COMET) trial is to compare remission and radiographic non-progression in patients treated with methotrexate monotherapy or with methotrexate plus(More)
OBJECTIVES To assess the efficacy and safety of abatacept in methotrexate-naive patients with early rheumatoid arthritis (RA) and poor prognostic factors. METHODS In this double-blind, phase IIIb study, patients with RA for 2 years or less were randomly assigned 1 : 1 to receive abatacept (approximately 10 mg/kg) plus methotrexate, or placebo plus(More)
BACKGROUND Clinical remission and low disease activity are essential treatment targets in patients with rheumatoid arthritis. Although moderately active rheumatoid arthritis is common, treatment effects in moderate disease have not been well studied. Additionally, optimum use of biologics needs further investigation, including the use of induction,(More)
OBJECTIVE To compare the efficacy and safety of subcutaneous (SC) and intravenous (IV) abatacept. METHODS In this phase IIIb double-blind, double-dummy, 6-month study, patients with rheumatoid arthritis (RA) and inadequate responses to methotrexate were randomized to receive 125 mg SC abatacept on days 1 and 8 and weekly thereafter (plus an IV loading(More)
BACKGROUND Several agents provide treatment for established rheumatoid arthritis (RA), but a crucial therapeutic goal is to delay/prevent progression of undifferentiated arthritis (UA) or very early RA. OBJECTIVE To determine the impact of T-cell costimulation modulation in patients with UA or very early RA. METHODS In this double-blind, phase II,(More)
BACKGROUND Biological agents offer good control of rheumatoid arthritis, but the long-term benefits of achieving low disease activity with a biological agent plus methotrexate or methotrexate alone are unclear. The OPTIMA trial assessed different treatment adjustment strategies in patients with early rheumatoid arthritis attaining (or not) stable low(More)
BACKGROUND Reaching the therapeutic target of remission or low-disease activity has improved outcomes in patients with rheumatoid arthritis (RA) significantly. The treat-to-target recommendations, formulated in 2010, have provided a basis for implementation of a strategic approach towards this therapeutic goal in routine clinical practice, but these(More)
OBJECTIVE 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. METHODS In this international, 6-month, open-label trial, patients had active RA, an inadequate response to anti-TNF(More)
This study is based on an expanded access program in which 511 patients suffering from active refractory rheumatoid arthritis (RA) were treated with intravenous infusions of infliximab (3 mg/kg+methotrexate (MTX)) at weeks 0, 2, 6 and every 8 weeks thereafter. At week 22, 474 patients were still in follow-up, of whom 102 (21.5%), who were not optimally(More)
We investigated the in vivo effects of cyclosporin A (CsA) on the production of interleukin (IL) 10, a cytokine with major immunosuppressive properties. To elicit IL-10 production in vivo, BALB/c mice were injected either with the anti-mouse CD3 145-2C11 monoclonal antibody (mAb) (25 micrograms) or with bacterial lipopolysaccharide (LPS) (20 micrograms).
