The 2023 EULAR recommendations provided an updated consensus on the pharmacological management of PsA with a new overarching principle and recommendation for 2023. Recent MOA safety data emphasised the importance of patient-specific benefit-risk profiling in JAKi therapy, and extra-musculoskeletal (MSK) manifestations related to PsA should be considered during drug selection.

February 2024

Bimekizumab was well tolerated in patients with PsA and TNFi-IR up to 52 weeks, with a safety profile consistent with that observed in prior studies. This study aimed to assess 52-week safety and efficacy of bimekizumab in patients with active PsA and prior IR/intolerance to TNFi.

September 2023

Data from this phase 3 RCT demonstrated that the efficacy of bimekizumab observed at 16 weeks remained consistent through to 52 weeks in the treatment of bDMARD-naïve patients with PsA. Patients who started the trial on placebo and switched to bimekizumab at week 16 showed similar improvements to those patients who were randomised to receive bimekizumab at the start of the trail. No new safety signals were identified.

Findings from post hoc analyses extend the knowledge base for radiographic benefits of filgotinib in patients with RA.

Differential Properties of Janus Kinase Inhibitors in the Treatment of Immune-mediated Inflammatory Diseases

Rheumatology (Oxford) 2023;63(2):298–308 doi 10.1093/rheumatology/kead448

JAKis differ in structure, which affects their inhibitory concentration for different JAKs.

This review by Taylor, et al. compares the pharmacological profiles of JAKis, including abrocitinib, baricitinib, filgotinib, peficitinib, tofacitinib, and upadacitinib.

This study by Tanaka, et al. shows that filgotinib reduces peripheral protein biomarkers associated with JAK/STAT signalling, inflammatory signalling, immune cell migration, and bone resorption in RA patients. Notably, filgotinib 200 mg significantly reduced IL-6, TNF, CXCL13 levels as early as Week 4.

The data gathered in this post-marketing surveillance study aligned with the previously established safety profile of tofacitinib, and reports were found to have consistent safety profiles in the treatment of both patient with PsA and RA. However, the results of this study should be interpreted considering the limitations of post-marketing surveillance studies.

This review by Taylor, et al. reviews the long-term safety and efficacy data for baricitinib. Results from several studies showed that baricitinib has greater efficacy and survival compared to TNF inhibitors, and that the rate of CDAI <10 for baricitinib-treated RA patients increased over the course of seven years. Data also showed that remission rates were higher in real-world evidence than in RCTs.

June 2023

Pots hoc analysis of peficitinib Phase 3 trials shows that continued treatment with peficitinib up to Week 52 is linked to improved remission rates in Asian patients with RA.

March 2023

Integrated analysis of the safety profile of upadacitinib demonstrates that it was generally well-tolerated in RA, PsA, AS and AD, with no new safety risks identified, compared with previous reports.
