Study type | Interventional |
To investigate whether a reduced-dose dosing regimen (1x500mg semiannually) of rituximab (RTX) (Mabthera®) is non-inferior in patients with rheumatoid arthritis (RA) whose disease is in persistent low disease activity (LDA) or clinical remission (REM) (pLDA/pREM) as compared to the standard dosing regimen of 1x1000mg semi-annual infusions.

Eligibility | Inclusion Criteria: - Diagnosis of RA according to the 2010 American College of Rheumatology (ACR) / European League Against Rheumatism (EULAR) classification criteria - Current treatment with RTX (at time of inclusion have already received at least 2 cycles of 1000mg RTX) at the Day-Clinic of the Division of Rheumatology of the Medical University of Vienna - Persistent low disease activity or clinical remission as defined below - Persistent clinical remission (pREM) will be defined as a simplified disease activity index (CDAI) (12) =2.8 measured at two time-points 6 months apart. The CDAI is calculated as follows: tender joint count (TJC) + swollen joint count (SJC) + patient's assessment of general health on a 100 mm visual analogue scale (GH) + evaluator's assessment of general health on a 100 mm visual analogue scale (EGH) - Persistent low disease activity (pLDA) will be defined as a CDAI =10 measured at two timepoints 6 months apart Patients who achieve REM at only either one of the two successive time-points will be considered as having pLDA with regard to the current trial Exclusion Criteria: - Patients = 18 yrs - Patients receiving RTX for a disease other than RA - Patients who fail to meet criteria for REM or LDA at either one of the two successive timepoints (i.e. having a disease activity >10 as measured by the clinical disease activity index, (CDAI)) |
