The impact of rheumatoid arthritis (RA) on work disability and job loss represents a significant economic burden. Recent developments in therapies targeted against tumor necrosis factor (TNF)have changed the approach to RA treatment by rapidly controlling the disease.
To compare work disability and job loss in early rheumatoid arthritis (RA) patients receiving adalimumab plus methotrexate (adalimumab + MTX) versus MTX alone.
The setting included a variety of medical centers providing treatment for rheumatoid arthritis.
In this multicenter, randomized, controlled trial, patients with RA for <2 years who had never taken MTX and who self-reported work impairment were randomized to adalimumab + MTX or placebo + MTX for 56 weeks.
Primary outcome was job loss of any cause and/or imminent job loss at or after week 16. Secondary outcomes included disease activity, function (Health Assessment Questionnaire [HAQ] score), and RA quality of life (RAQoL) questionnaire score. Work was evaluated with work diaries and the RA Work Instability Scale.
The comparison was treatment using MTX alone.
Although job loss during the 56-week study was significantly lower with adalimumab + MTX (14 of 75 patients) compared with MTX alone (29 of 73 patients; P = 0.005), the primary endpoint was not met (12 of 75 versus 20 of 73 patients; P = 0.092), likely owing to early drop out in the MTX group. There were significant improvements in American College of Rheumatology 20% response criteria, 28-joint Disease Activity Score, HAQ, RAQoL, and working time lost in the adalimumab + MTX group. Twenty-four serious adverse events were reported in 17 participants, with no differences between groups.
Adalimumab + MTX reduced job loss and improved productivity in early RA when compared with MTX alone, which supports the early use of anti tumor necrosis factor therapy and suggests its cost efficacy.
