Risk of venous thromboembolism with tofacitinib versus tumor necrosis factor inhibitors in cardiovascular risk-enriched rheumatoid arthritis patients

Arthritis Rheumatol 2024 doi: 10.1002/art.42846 Epub ahead of print https://pubmed.ncbi.nlm.nih.gov/38481002/

This post hoc analysis of ORAL Surveillance showed that incidence of venous thromboembolism (VTE) events was higher in patients with RA treated with tofacitinib (10>5mg BID) versus TNFi. Across treatments, VTE risk factors (age, BMI, and VTE history) were aligned with previous studies in the general RA population.

Efficacy and safety of JAK inhibitors in rheumatoid arthritis: update for the practising clinician

Nat Rev Rheumatol 2024;20(2):101–115 DOI: 10.1038/s41584-023-01062-9

The observed benefit:risk ratio strongly favours JAKi use in the majority of patients, and HCPs should consider and adhere to guidance on high-risk patients where applicable. Szekanecz et al summarised the safety and efficacy of approved JAKis tofacitinib, baricitinib, upadacitinib, and filgotinib to aid in clinical decision making.

Post hoc analysis of ORAL Surveillance data highlights that active disease in RA leads to higher risk of adverse medical events, regardless of medication used.

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.

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.

Data suggest that an important difference between P123LTE and ORAL Surveillance was the proportion of patients with a history of atherosclerotic CV disease (ASCVD).

Weitz, et al. analyse 291 protein biomarkers and three genetic markers and do not identify a clear mechanistic explanation for higher rates of venous thromboembolism (VTE) with tofacitinib in the ORAL Surveillance study.

October 2022

Post hoc analysis from ORAL Surveillance observes higher major adverse cardiovascular events (MACE) risk with tofacitinib vs TNFi in patients with RA and history of atherosclerotic cardiovascular disease (ASCVD).

A review of JAK-STAT signalling in the pathogenesis of spondyloarthritis and the role of JAK inhibition

Rheumatology (Oxford). 2021. Epub ahead of print. doi: 10.1093/rheumatology/keab740.

JAK inhibitors are likely to become an important part of the overall treatment paradigm for spondyloarthritis (SpA).Although not fully understood, the pathogenesis of SpA is complex and thought to involve both environmental and genetic factors that together elicit a chronic inflammatory response involving the innate and adaptive immune systems. Several different cytokines, TNF, IL-17A, IL-12/23 and IL-23, which are directly/indirectly affected by JAK molecules, are involved in the pathogenesis o...

Effects of One-Year Tofacitinib Therapy on Bone Metabolism in Rheumatoid Arthritis

Osteoporos Int 2021 Feb 9 DOI 10.1007/s00198-021-05871-0

Thought to be the first study of its kind, Hamar, et al. have demonstrated the effect of one-year tofacitinib treatment on bone mineral density (BMD) in RA patients. While the association between RA and osteoporosis is well known, and evidence indicates that up to 70% of these patients have reduced BMD, little information is available on how the JAK inhibitor tofacitinib affects bone status, areal and volumetric BMD, and bone turnover markers. In this prospective study, 30 patients were assessed...
