Ultrasound to Guide Treatment Decisions in Patients With Rheumatoid Arthritis According to a T2T Approach

Обзор

Population Patients with a diagnosis of Rheumatoid Arthritis (RA), moderate or high clinical disease activity (CDAI\>10) despite conventional synthetic (cs)DMARD(s) or bs-ts-DMARDs therapy for ≥3 months, and a maximum of 2 swollen joints (out of 44 joints) Study design Randomised multicentre, parallel-arm clinical study Primary objective Non-inferiority of the experimental arm (i.e. clinical therapy together with ultrasound guided treatment decision) in comparison to the control arm (clinically guided decision) concerning the proportion of patients reaching low disease activity (CDAI ≤10) and a minimal clinical important improvement (MCII: improvement of ≥6 points if starting from moderate disease activity, any case starting from high disease activity and achieving low disease activity) or remission according to ACR/EULAR index-based remission criteria (CDAI ≤2.8/Boolean remission) at week 24. Intervention This is a randomised multicentre, national, parallel-arm clinical study. Patients with a diagnosis of RA, moderate or high clinical disease activity (CDAI\>10) despite conventional synthetic (cs)DMARD(s) or b-tsDMARDs therapy for ≥3 months, and a maximum of 2 swollen joints (out of 44 joints) will be included and randomized to one of the following two strategic arms: 1. Clinical decision strategy: All patients receive a new course of b-ts-DMARDs, with or without concomitant cDMARD. If a CDAI ≤10 is not achieved after 12 weeks, patients are switched to a bDMARD or tsDMARD. The decision on which b/tsDMARD to use at week 12 is at the discretion of the investigator. 2. Clinical plus ultrasound-based decision strategy. All patients in this group will be evaluated by ultrasound at 44 joints. In case of clinically-verified plus ultrasound verified inflammation, patients will receive a new b-ts-DMARD while continuing or not background csDMARD(s) therapy. If a CDAI ≤10 is not achieved after 12 weeks, patients are again evaluated by ultrasound at 44 joints. In case clinically-verified plus ultrasound-verified inflammation is present, patients are switched to a bDMARD or tsDMARD. The decision on which b/tsDMARD to use is at the discretion of the investigator. In case clinically-verified plus ultrasound-verified inflammation is absent, patients receive step-up pain therapy while background treatment will be continued. Sample size 158 patients Time plan * Total duration of the study: 72 months * Active phase for each patient: 48 weeks (24 weeks for the interventional treatment strategy and 24 weeks for follow-up visit) * Recruitment: 60 months

Вмешательства

• Диагностический тест Ultrasound
  At baseline and at weeks 12, 24 and 48, patients will undergo an ultrasound examination of 44 joints by one investigator, who is blinded to the strategic arm and all clinical data. The following joints will be assessed: bilateral wrists (distal radio-ulnar joint, radio-carpal, mid-carpal recesses), 1st - 5th MCP, 1st - 5th PIP, elbows, glenohumeral, acromioclavicular, sternoclavicular, knees, ankles and 1st - 5th MTP. At wrists, MCP and PIP joints, palmar and dorsal sites including synovial rece
