Comparative study of the efficacy and safety of tofacitinib, baricitinib, upadacitinib, and filgotinib versus methotrexate for disease-modifying antirheumatic drug-naive patients with rheumatoid arthritis

초록

An assessment of the relative efficacy and tolerability of tofacitinib, baricitinib, upadacitinib, and filgotinib compared to those of methotrexate (MTX) was performed in disease-modifying antirheumatic drug (DMARD)-naive patients with rheumatoid arthritis (RA). We performed a Bayesian network meta-analysis to combine direct and indirect evidence from randomized controlled trials (RCTs) so as to examine the efficacy and safety of tofacitinib, baricitinib, upadacitinib, filgotinib, and MTX in DMARDnaive RA patients. Four RCTs comprising 2185 patients met the inclusion criteria. The ranking probability based on the surface under the cumulative ranking curve (SUCRA) indicated that upadacitinib 15mg had the highest probability of achieving the American College of Rheumatology 20% (ACR20) response rate, followed by baricitinib 4mg, tofacitinib 5mg, filgotinib 200mg, and MTX. Tofacitinib, baricitinib, upadacitinib, and filgotinib treatments achieved significantly higher ACR50 and ACR70 responses compared to MTX. Tofacitinib 5mg had the highest probability of achieving the ACR50 and ACR70 response rates, followed by upadacitinib 15mg, baricitinib 4mg, filgotinib 200mg, and MTX. The safety analysis based on serious adverse events, adverse events (AEs), and withdrawals due to AEs revealed no statistically significant differences between the respective intervention groups. In conclusion, tofacitinib, baricitinib, upadacitinib, and filgotinib were effective treatment options for DMARD-naive RA patients, suggesting a difference in efficacy and safety among the different JAK inhibitors.
