Differential Properties of Janus Kinase Inhibitors in the Treatment of Immune-mediated Inflammatory Diseases
Rheumatology (Oxford) 2023 doi 10.1093/rheumatology/kead448 Epub ahead of print
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.
Filgotinib Modulates Inflammation-Associated Peripheral Blood Protein Biomarkers in Adults with Active Rheumatoid Arthritis and Prior Inadequate Response to Methotrexate
Rheumatol Ther. 2023 doi 10.1007/s40744-023-00583-9 Epub ahead of print
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.
Post-Marketing Safety Surveillance of Tofacitinib over 9 Years in Patients with Psoriatic Arthritis and Rheumatoid Arthritis
Rheumatol Ther. 2023 doi: 10.1007/s40744-023-00576-8 Epub ahead of print
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.
Post Hoc Analysis of Patients with Rheumatoid Arthritis Under Clinical Remission in Two Japanese Phase 3 Trials of Peficitinib Treatment (RAJ3 and RAJ4)
Mod Rheumatol. 2023 doi: 10.1093/mr/road059 Epub ahead of print
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.
Safety Profile of Upadacitinib over 15 000 Patient-years Across Rheumatoid Arthritis, Psoriatic Arthritis, Ankylosing Spondylitis and Atopic Dermatitis
RMD Open. 2023;9(1):e002735 doi: 10.1136/rmdopen-2022-002735
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.
Bimekizumab In Patients with Active Psoriatic Arthritis and Previous Inadequate Response or Intolerance to Tumour Necrosis Factor-Α Inhibitors: A Randomised, Double-Blind, Placebo-Controlled, Phase 3 Trial
Lancet. 2023 doi: 10.1016/S0140-6736(22)02303-0
This study showed rapid and clinically meaningful improvements with bimekizumab treatment in patients experiencing active PsA and showing an inadequate response or intolerance to TNFα inhibitors. Its chief aim was to evaluate the efficacy and safety of bimekizumab in patients with an inadequate response or intolerance to TNFα inhibitors.
Bimekizumab in Patients with Psoriatic Arthritis, Naive To Biologic Treatment: A Randomised, Double-blind, Placebo-controlled, Phase 3 Trial (BE OPTIMAL)
Lancet. 2023 doi: 10.1016/S0140-6736(22)02302-9
This study showed that bimekizumab treatment resulted in clinically meaningful and consistent improvements across multiple measures in bDMARD-naïve patients with active PsA. It aimed to assess the efficacy and safety of bimekizumab in patients with active PsA who were naive to bDMARDs.
Evaluation of VTE, MACE, and Serious Infections Among Patients with RA Treated with Baricitinib Compared to TNFi: A Multi-Database Study of Patients in Routine Care Using Disease Registries and Claims Databases
Rheumatol Ther. 2022. Epub ahead of print doi: 10.1007/s40744-022-00505-1
Salinas, et al. evaluate baricitinib safety with respect to VTE, MACE, and serious infection relative to TNFi in patients with RA, in routine care and observe an increased risk of VTE in patients taking baricitinib, compared to TNFi.
Efficacy and Safety of Filgotinib in Patients with High Risk of Poor Prognosis Who Showed Inadequate Response to MTX: A Post Hoc Analysis of the FINCH 1 Study
Rheumatol Ther. 2022. Epub ahead of print doi: 10.1007/s40744-022-00498-x
Post hoc analysis from the FINCH 1 study highlights filgotinib as a potential beneficial treatment option for patients with RA who have had inadequate response to MTX and have high risk of disease progression and poor prognosis.
