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.

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 meta-analysis by Wei, et al. found that JAKi therapy was not associated with a higher risk of MACE than treatment with adalimumab, abatacept, or placebo. However, a higher incidence of all-cause mortality was observed with tofacitinib treatment than with adalimumab treatment.

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.

JAK Inhibitors and the Risk of Malignancy: A Meta-analysis Across Disease Indications

Ann Rheum Dis. 2023;82(8):1059–1067 doi: 10.1136/ard-2023-224049

The objective of this study was to estimate the association of JAKi with the incidence of malignancy, compared with placebo, TNFi and MTX.

Herpes zoster in Patients with Inflammatory Arthritides or Ulcerative Colitis Treated with Tofacitinib, Baricitinib or Upadacitinib: A Systematic Review of Clinical Trials and Real-world Studies

Overall, this evidence supports that HZ-risk is a “class” effect of JAKi, observing a higher risk compared to other non-biologic/biologic drugs . This study aimed to systematically review the incidence of HZ among RA, PsA, AS and UC patients treated with TOFA, BARI or UPA.

November 2022

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.

October 2022

Data from the JAK-pot collaboration of registries show that cycling JAKinibs and switching to a bDMARD appear to have similar effectiveness, after failing the first JAKinib.

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.
