Main objective

Scope: Therapy

The main objective of this open label multicenter randomised controlled pragmatic superiority trial is to investigate the optimal treatment/tapering strategy with rituximab for patients with rheumatoid arthritis with a goal of reducing disease impact.

Secondary objectives 1

  1. The main secondary objective is to investigate the optimal treatment/tapering strategy with rituximab for patients with rheumatoid arthritis to reduce disease activity.

Patients will be 1:1 randomised to the experimental arm or the active comparator arm.
Randomised Controlled None Active comparator arm: interval prolongation: Arm in which rituximab will be administrated in a fixed dose of 1 x 1000 mg intravenously (IV) based on interval prolongation (treatment according to the current Belgian reimbursement criteria for retreatment with rituximab: retreatment in case of a relapse of rheumatoid arthritis with a Disease Activity Score in 28 joints (DAS28) ≥3.2 and last administration of rituximab at least 24 weeks before).
Experimental arm: disease activity guided dose reduction: Arm in which patients taper rituximab based on disease activity-guided dose reduction. Patients in this arm will receive rituximab at fixed intervals of 24 weeks, and the administered dose of rituximab will be reduced in case of a Disease Activity Score in 28 joints (DAS28) ≤3.2 according to the following sequence: 1 x 1000 mg intravenously (IV) (maximum), 1 x 500 mg IV, 1 x 200 mg IV (minimum). In case of a DAS28 score >3.2, the last effective dose will be administered.
