Brief Summary

The objective of this study is to identify a panel of immunological molecular and cellular biomarkers able to predict the success of major dose-reduction or discontinuation of abatacept in rheumatoid ...

Detailed Description

Parameters studied at different time points (before initiation of abatacept if sample is available in our biocollection; prior to dose tapering; prior to discontinuation) ACPA (anti-citrullinated prot...

Eligibility Criteria

Inclusion

  • Rheumatoid arthritis (RA) patients (\> pr = 18 years) fulfilling the 2010 ACR/EULAR criteria
  • Associated to high levels (\> 3 x upper limit of normal in UA/ml) of ACPA measured by the usual anti-CCP(cyclic citrullinated proteins)2 test at the start of abatacept treatment
  • Receiving IV (intravenous) or SC (subcutaneous) abatacept alone or in combination with a conventional Disease Modyfying AntiRheumatic Drugs (cDMARD) (methotrexate, leflunomide, sulfasalasin in monotherapy or in combination) according to the usual scheme or in tapering phase
  • Without intra-articular injections of corticosteroids during the last 6 months prior to down-titration of abatacept
  • Having discontinued corticosteroids at he time of entrance in the study
  • In deep remission (Disease Activity Score (DAS) 28 ESR (or CRP) \< 2.6 without clinical synovitis) since at least 1 year
  • In sonographic remission at the time of enrollment (absence of PD (Power Doppler)-positive synovitis on 28 joints defined by a score \< 2 on a 0-3 semi-quantitative scale for each joint)

Exclusion

  • Age \< 18 years
  • RA negative for ACPA (anti-citrullinated proteins antibodies) or not fulfilling ACR/EULAR criteria
  • Abatacept discontinuation due to serious adverse event, loss of efficacy or pregnancy project
