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.

Biomarkers to predict risk of venous thromboembolism in patients with rheumatoid arthritis receiving tofacitinib or tumour necrosis factor inhibitors

RMD Open. 2022;8(2):e002571 doi: 10.1136/rmdopen-2022-002571

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.

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.

Risk of major adverse cardiovascular and venous thromboembolism events in patients with rheumatoid arthritis exposed to JAK inhibitors versus adalimumab: a nationwide cohort study

Ann Rheum Dis. 2022. doi: 10.1136/ard-2022-222824

Real-world population study of patients with RA provides reassuring data regarding the risks of major adverse cardiovascular events (MACEs) and venous thromboembolism events (VTEs) in patients initiating a JAKinib versus adalimumab, including patients at high risk of cardiovascular diseases.

Venous Thromboembolism with JAK Inhibitors and Other Immune-Modulatory Drugs: a Swedish Comparative Safety Study Among Patients with Rheumatoid Arthritis

Ann Rheum Dis. 2022. doi: 10.1136/ard-2022-223050

Nationwide register-based study in Sweden finds that patients with RA treated with JAKinibs in routine clinical practice are at increased risk of venous thromboembolism (VTE), compared with those treated with bDMARDs, an increase numerically confined to pulmonary embolism.

Identification of novel off targets of baricitinib and tofacitinib by machine learning with a focus on thrombosis and viral infection

Sci Rep. 2022 doi: 10.1038/s41598-022-11879-1

Established machine learning approaches, based on ligand similarity, identified previously unknown off-target interactions of baricitinib and tofacitinib, and adds to the evidence that these JAK inhibitors are promiscuous binders, and highlight the potential for repurposing.

Cardiovascular Safety During Treatment with Baricitinib in Rheumatoid Arthritis

Arthritis Rheumatol. 2019 Jul;71(7):1042-1055.

This study indicates no association between exposure to BARI and MACE, arterial thrombotic events (ATE), or congestive heart failure (CHF). Overall IRs for venous thromboembolic event (VTE) in BARI-treated patients falls within the reported range for patients with RA.RA patients have a greater risk of cardiovascular (CV) diseases of arterial ischemic origin, and an increased risk of VTE. Studied frequencies of thromboembolic events in RA populations in the last decade has been reported as 2–3x h...

Comparative Risk of Venous Thromboembolism with Tofacitinib versus Tumour Necrosis Factor Inhibitor: A Cohort study of Rheumatoid Arthritis Patients

Desai RJ, et al. Arthritis Rheumatol. 2019 June;71(6):892-900.

Occurrences of venous thromboembolism (VTE) in 50, 865 RA patients initiating Tofacitinib (TOF) or a TNF inhibitor (TNFi) was infrequent. No significant risk of VTE for TOF versus TNFi was observed.Safety concerns of JAK inhibitor BARI include potentially increased risk of VTE at the higher 4 mg dose. It’s unclear if this is attributable to JAK-inhibition and extends to TOF. This study compared the risk of VTE with TOF, versus TNFi in real-world settings with RA patients.RA patients initiating T...

Safety Profile of Baricitinib in Patients with Active Rheumatoid Arthritis with over 2 Years Median Time in Treatment

J Rheumatol. 2019 Jan;46(1):7-18. DOI: 10.3899/jrheum.171361

Baricitinib (BARI) showed an acceptable 5.5-year safety profile in this integrated analysis of patients with moderate-to-severe, active RA.This study evaluated the safety profile of the oral, once daily Janus kinase inhibitor, BARI, in adults with moderately to severely active RA. Data from eight randomised clinical trials and one long-term extension study were pooled and analysed for placebo comparison and dose response.There were 3492 patients who received BARI for a total of 6637 patient-yea...
