Abstract

Abstract : Background: AVERT (A ssessing V ery E arly R heumatoid arthirits T reatment) is a Phase IIIb, randomized, active-controlled trial to evaluate the efficacy and safety of abatacept (ABA) in combination with methotrexate (+ MTX) in patients (pts) with early RA. Objectives: To assess joint damage progression by magnetic resonance imaging (MRI) in pts with early RA from the AVERT study who were treated with ABA + MTX or ABA monotherapy, compared with MTX alone. Methods: MTX-naïve, anti-CCP2+ pts with early RA (active synovitis in ≥2 joints for ≥8 weeks, DAS28 (CRP) >3.2 and onset of symptoms within ≤2 yrs) were included. Pts were randomized to 12 mths of weekly SC ABA 125 mg + MTX, ABA 125 mg monotherapy or MTX alone. Pts with DAS28 (CRP) <3.2 at Mth 12 entered a 12-mth withdrawal period with no treatment. All pts with protocol-defined flare after Mth 15 could receive open-label ABA + MTX. Gadolinium-enhanced MRI of the dominant hand-wrist was performed on all pts at baseline and at Mths 6, 12, 18 and 24. Changes from baseline in synovitis, osteitis and bone erosion MRI scores were assessed up to Month 18 in this analysis. Results: During the 12-mth treatment period, benefits in synovitis, osteitis and erosion scores were numerically greater for ABA + MTX than for MTX alone; while numerically greater benefits were observed in synovitis and osteitis scores for ABA monotherapy than for MTX alone (Table 1 ). A post hoc analysis of pts who maintained DAS28 (CRP) <2.6 to Mth 18 after treatment withdrawal did not show evidence of MRI progression compared to Mth 12 in those pts. Conclusions: Consistent with the clinical outcomes of the AVERT study in pts with early RA with high disease activity, there were greater reductions in MRI outcomes with abatacept treatment in combination with MTX than with MTX alone. MRI changes with abatacept monotherapy treatment were intermediate between abatacept in combination with MTX and MTX treatment alone. Disclosure of Interest: C.
