Abstract

Abstract : Background: Factors predictive of relapse need to be identified to aid therapy withdrawal decisions for patients with RA achieving remission with treatment. AVERT (NCT01142726 ) was a Phase IIIb, randomized, active-controlled trial in patients with early RA. 1 After a 12-month, double-blind treatment period with abatacept + MTX, or abatacept or MTX monotherapy, patients with DAS28 [CRP] <3.2 could enter a 12-month withdrawal period (all treatment stopped). Objectives: To evaluate post hoc whether MRI scores, patient characteristics and disease activity at Month 12 were predictors of clinical relapse at Month 18 and Month 24 after treatment withdrawal in AVERT. Methods: Synovitis, erosion and bone oedema in the dominant hand and wrist MRI were scored at Month 12 using the RA MRI scoring system (RAMRIS). Patient characteristics (pain, age, weight, HAQ-DI) and disease measures (CRP, SJC28, TJC28, DAS28 [CRP], CDAI, SDAI) were recorded at Month 12. The influence of these factors on the proportion of patients who relapsed (doubling of TJC28 and SJC28, and DAS28 [CRP] ≥1.2 increase relative to Month 12) by Month 18 and Month 24 was assessed. Results: A total of 172 patients achieving DAS28 remission (DAS28 [CRP] <2.6) at Month 12 in any treatment group were included in the analysis. Numbers of patients who relapsed at Month 18 and Month 24 were 100 and 113, respectively. Of the patient characteristics, disease activity and imaging factors analysed at Month 12, only MRI synovitis, erosion and oedema scores, as well as HAQ-DI scores, were significantly associated (p<0.05) with relapse status at both Month 18 and Month 24 (Table). Conclusions: MRI and HAQ-DI scores in patients in DAS28 remission predicted clinical relapses 6 and 12 months after complete drug withdrawal in the AVERT trial. The clinical decision on whether to withdraw therapy in MTX-naïve patients with RA in remission may benefit from an assessment of imaging and physical function prior to drug withdrawal.
