Rates of MACE and VTE events in patients with RA or PsA treated are consistent across 15 mg and 30 mg doses of upadacitinib, and comparable with active comparators adalimumab and MTX. Several risk factors were also identified for MACE and VTE events in patients with RA.

Effects of 1-year Tofacitinib Therapy on Angiogenic Biomarkers in Rheumatoid Arthritis

Rheumatology (Oxford) 2023; 62(SI3):SI304–SI312 doi 10.1093/rheumatology/kead502

This study by Kerekes, et al. investigated the relationship between tofacitinib therapy, angiogenic biomarker levels, and vascular inflammation and function in RA patients. The authors found that tofacitinib treatment reduced the production of bFGF, PlGF and IL-6, which may inhibit synovial and aortic inflammation.

The results of this study show that anti-IL-12/23, JAK inhibitors, and anti-TNF-α were associated with slightly higher risk of MACE compared with placebo. The risk was no different between biologic treatments, and the magnitude of risk did not differ between IMID type.

This retrospective inception cohort study investigated RA patients starting a new bDMARD or JAKi prescription between 01 August 2018 and 31 January 2022 from IQVIA’s Dutch Real-World Data Longitudinal Prescription database.

This study by Bergman, et al. showed that RA patients are significantly more likely to adhere to upadacitinib within the first 12 months of prescription versus adalimumab, baricitinib, and tofacitinib. There was also a significantly lower risk of discontinuation for upadacitinib versus the other treatment prescriptions.

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.

Fleischmann, et al investigated the safety and efficacy of otilimab versus tofacitinib and placebo in RA patients treated with MTX (contRAst 1) or csDMARDs (contRAst 2). They found that while otilimab achieved the primary endpoint of ACR20 versus placebo in Week 12, it did not demonstrate non-inferiority to tofacitinib.

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.

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.

Post-hoc analysis of two tofacitinib phase three studies concludes that tofacitinib treatment resulted in improvements in enthesitis in patients with PsA, regardless of baseline location or severity.
