Key clinical point: Abatacept appeared to be more efficacious and safer than adding or switching to conventional synthetic disease-modifying antirheumatic drugs (csDMARD) in patients with rheumatoid arthritis (RA) of any age who were refractory to csDMARDs.
Major finding: At 24 weeks, European League Against Rheumatism good or moderate response was achieved by a significantly higher proportion of older patients aged 65 years or above (odds ratio [OR] 7.770; P < .0001) and younger patients (OR 4.089; P = .005) receiving abatacept vs. csDMARDs. Few serious adverse events were reported.
Study details: This was a prospective, multicenter study involving 202 bio-naive, csDMARD-refractory patients with RA. The patients were categorized into older (n=67) and younger (n=47) patients receiving abatacept and older (n=48) and younger (n=40) patients receiving csDMARDs.
