Abstract
Objectives: To assess the effectiveness of canakinumab (CAN) in controlling clinical and laboratory inflammation by achieving complete control of cardinal disease manifestations and full normalization of laboratory inflammatory markers. Methods: Data were obtained from the international AutoInflammatory Disease Alliance (AIDA) network registry, dedicated to monogenic autoinflammatory diseases. The assessment included both retrospective and prospective real-world data. Results: In total, 158 FMF patients treated with CAN were enrolled. Complete clinical-laboratory response was observed in 45.6% of patients at 3 months, 58.6% at 12 months and 55.2% at the last follow-up, after a mean treatment duration of 45 months. Partial response occurred in 16.5%, 12.5% and 16.8% at the same timepoints, respectively. Complete absence of clinical manifestations was observed in more than 80% of patients at each timepoint. Inflammatory markers normalized significantly by the 3-month assessment. The probability of achieving and maintaining complete response and full laboratory control appeared higher in patients reaching these outcomes by 3 months, although it remained substantial in other patients as well. Complete response was associated with a relapsing-remitting disease course and fewer annual attacks. Nearly all patients maintained stable organ damage scores, and therapy discontinuation due to inefficacy was rare (≤6%). Conclusion: CAN is effective in achieving rapid and sustained clinical and laboratory control in FMF, including stringent endpoints of complete response. Early effectiveness may favour better long-term outcomes, but delayed achievement of complete response and full laboratory control is not uncommon. This study confirms CAN as an effective, and durable therapeutic option in FMF.
