In this post hoc analysis by Deoodhar, et al., the authors found that tofacitinib demonstrated greater efficacy than placebo in bDMARD-naïve and TNFi-IR AS patients. They also found that safety event rates for tofacitinib therapy were numerically higher in the TNFi-IR subgroup than the bDMARD-naïve subgroup.

The majority of patients receiving persistent risankizumab therapy achieved clear or clear/almost clear skin at 12 months and patients reported significant reductions in DLQI scores, PROs (fatigue, skin pain, overall itch), and work and activity impairment.

The efficacy and safety of updacitinib in bDMARD-IR patients with AS were sustained through to one year in an open-label extension of the SELECT-AXIS 2 study.

In the UPJOINT open label study, the proportion of patients with PsA, and an inadequate response to csDMARDs or bDMARDs, who achieved minimal disease activity with upadacitinib was in line with the results of previous studies at 24 weeks. No new safety signals were identified.

Janus Kinase Inhibitor—Tofacitinib Associated with Pemphigus: An Analysis of the FDA Adverse Event Reporting System Data

ExpExpert Opin Drug Saf. 2023;22(12):1317–1320 doi: 10.1080/14740338.2023.2248872

This study presents initial data suggesting an association between the use of JAK inhibitors and pemphigus. This research used the FAERS database to investigate connections between JAK inhibitor usage and the occurrence of pemphigus as an adverse event.

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

Whole blood transcriptome profiling reveals differential gene expression in patients with active PsA from the DISCOVER-1 and DISCOVER-2 clinical studies in comparison with healthy controls.

High levels of clinical responses were seen throughout the first 48 weeks with bimekizumab treatment. These were maintained to Week 96 in patients with moderate-to-severe plaque PsO.

This study by Harrold, et al. showed that RA patients initiating upadacitinib reported improvements in RAPID3, pain, stiffness, and fatigue as early as Week 1, with 37.5% achieving RAPID3 LDA at Week 12. TNFi-experienced patients had similar outcomes.
