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

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).

September 2022

Post hoc analysis, using the final dataset from ORAL Surveillance, reveals a higher risk of non-serious infections and herpes zoster with tofacitinib vs TNFi, and higher risk of serious infection events with tofacitinib 10 mg BID versus TNFi, particularly in patients aged ≥65 years.

July 2022

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.

June 2022

Navarro-Compán et al, determined the effectiveness of tofacitinib in patients with active ankylosing spondylitis in a Phase III, randomised, double-blind, placebo-controlled trial.

Putting the data into context, Winthrop, et al. conclude that the ORAL Surveillance data are not dissimilar to those from the original developmental programme, which suggested additional safety concerns at the 10 mg dosage and that resulted in the 5 mg twice daily dosage as the approved dose for RA.Following the recent results of the ORAL Surveillance (ORALSURV) study, and the consequent changes to the utilisation of JAKinibs, made by the regulatory authorities, Winthrop, et al. aim to put the O...

This was an exploratory post hoc analysis of pooled data, from over 2000 patients in three Phase 3 studies of tofacitinib, which demonstrates an association between tofacitinib treatment and significantly greater improvements in fatigue, sleep, and health-related quality of life (HRQoL), compared with placebo.

Data from the Swedish Rheumatology Quality Register and Swedish Registries, show a higher treatment retention and overall equivalent or better treatment response on baricitinib, compared with bDMARDs or tofacitinib, but no statistically significant differences between tofacitinib and bDMARDs.In this largest population-based study to date, comparing RA patients initiating baricitinib, tofacitinib or bDMARDs, Barbulescu, et al. help to fill some of the current knowledge gaps surrounding the effica...

Post-hoc analysis shows that dosing up from tofacitinib 5 to 10 mg BID is associated with improved efficacy for up to 12 months, versus staying on 5 mg BID, and dosing down from 10 to 5 mg BID is not generally associated with a significant loss of efficacy.Although clinical trials have generally shown no significant differences, in terms of efficacy and safety, when switching tofacitinib dose up or down, these per-protocol switches are not directly informative for clinical decision-making in dai...
Systematic review and network meta-analysis highlight that RA patients who receive recommended doses of the five approved JAK inhibitors (tofacitinib, baricitinib, upadacitinib, filgotinib, and peficitinib) are likely to experience an increase in serum low- and high-density lipoprotein (LDL and HDL) levels.JAK inhibitors have been associated with alterations in levels of LDL and HDL cholesterol, which may lead to dyslipidaemia (an important risk factor for cardiovascular disease). However, the e...
