Cost-Effectiveness Analysis of Two Rituximab Retreatment Regimens for Longstanding Rheumatoid Arthritis

摘要

ObjectiveRituximab (RTX) is licensed for second-line treatment of rheumatoid arthritis (RA) after first tumor necrosis factor (TNF) inhibitor failure. RTX is generally administered intravenously at 1 gm 2 weeks apart, and the retreatment is scheduled at the time of clinical relapse (regimen 1). A more intensive regimen is proposed with a fixed full cycle after 6 months (regimen 2) if remission is not reached. A cost-effectiveness analysis (CEA) compared these 2 regimens of RTX administration in patients with longstanding RA based on data provided by an observational study.
