Abstract
Background
In the present study, we explored the effects of immediate induction therapy with the anti-tumour necrosis factor (TNF)α antibody infliximab (IFX) plus methotrexate (MTX) compared with MTX alone and with placebo (PL) in patients with very early inflammatory arthritis.
Methods
In an investigator-initiated, double-blind, randomised, placebo-controlled, multi-centre trial (ISRCTN21272423,
http://www.isrctn.com/ISRCTN21272423), patients with synovitis of 12 weeks duration in at least two joints underwent 1 year of treatment with IFX in combination with MTX, MTX monotherapy, or PL randomised in a 2:2:1 ratio. The primary endpoint was clinical remission after 1 year (sustained for at least two consecutive visits 8 weeks apart) with remission defined as no swollen joints, 0–2 tender joints, and an acute-phase reactant within the normal range.
Results
Ninety patients participated in the present study. At week 54 (primary endpoint), 32% of the patients in the IFX + MTX group achieved sustained remission compared with 14% on MTX alone and 0% on PL. This difference (p < 0.05 over all three groups) was statistically significant for IFX + MTX vs PL (p < 0.05), but not for IFX + MTX vs MTX (p = 0.10), nor for MTX vs PL (p = 0.31). Remission was maintained during the second year on no therapy in 75% of the IFX + MTX patients compared with 20% of the MTX-only patients.
Conclusions
These results indicate that patients with early arthritis can benefit from induction therapy with anti-TNF plus MTX compared with MTX alone, suggesting that intensive treatment can alter the disease evolution.
