Relative efficacy and safety of Janus kinase inhibitors for the treatment of active psoriatic arthritis: a network meta-analysis.

objectiveTo determine the relative effectiveness and safety of Janus kinase (JAK) inhibitors in active psoriatic arthritis (PsA) patients. MATERIALS AND

methodsA Bayesian network meta-analysis was performed using data from randomized controlled trials (RCTs) to evaluate the effectiveness and safety of upadacitinib 30 mg, upadacitinib 15 mg, tofacitinib 10 mg, tofacitinib 5 mg, and filgotinib 200 mg in active PsA patients.

resultsFive RCTs including 2539 patients fulfilled the inclusion criteria. The surface under the cumulative ranking curve (SUCRA) revealed that filgotinib 200 mg had the highest probability of reaching a 20% American College of Rheumatology (ACR20) response rate, followed by upadacitinib 30 mg, upadacitinib 15 mg, tofacitinib 10 mg, tofacitinib 5 mg, and placebo. Upadacitinib 30 mg had the highest probability of achieving the ACR50 and ACR70 response rates, followed by upadacitinib 15 mg, filgotinib 200 mg, tofacitinib 10 mg, tofacitinib 5 mg, and placebo. The SUCRA rating based on the Psoriasis Area and Severity Index response rate of at least 75% (PASI75) showed that tofacitinib 10 mg had the highest probability of achieving this response, followed by upadacitinib 15 mg, filgotinib 200 mg, tofacitinib 5 mg, and placebo. Safety analyses evaluated adverse events (AEs) and serious adverse events (SAEs), but no statistically relevant differences were found.

conclusionBased on the ACR response rates, filgotinib 200 mg and upadacitinib 30 mg were the most effective, whereas tofacitinib 10 mg was the most effective treatment for PsA based on PASI75. However, treatment options were similar with regard to AEs and SAEs.
