Oral surveillance and JAK inhibitor safety: the theory of relativity

Nat Rev Rheumatol. 2022. Epub ahead of print doi: 10.1038/s41584-022-00767-7

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...

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...

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...

This post hoc analysis provides the first detailed description of the management and outcomes of HZ events in tofacitinib RA and PsA clinical studies.While prior studies have characterised the increased HZ risk with JAKinibs, the clinical management of these events has not been detailed.To this end, Winthrop, et al. analysed data from 21 RA and 3 PsA clinical studies to evaluate how HZ events and their sequelae were clinically managed during the RA and PsA tofacitinib clinical development progra...
