The most common immune system-related AEs in patients treated with IL-17 inhibitors are mucosal and opportunistic infections.

Interleukin (IL)-17 inhibitors are a series of biological drugs used to treat a number of conditions, including ankylosing spondylitis, a disease characterised by immune system dysregulation and joint inflammation. Azadeh, et al. aimed to assess the risk of immune system-related AEs due to targeting IL-17 or IL-17R.

Post hoc analysis of the RA-BEGIN trial finds that, over a one-year period, patients treated with baricitinib (monotherapy or in combination with methotrexate [MTX]) report greater pain relief and a more rapid attainment of clinically meaningful thresholds of pain improvement, than patients who receive MTX monotherapy.Often overlooked, when treating RA solely to a disease activity target, patient-reported pain is common in RA, even in those reaching inflammatory remission. The fact that pain per...

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...
Vaccine sub-study of the BALANCE-EXTEND upadacitinib trial finds that approximately two-thirds of patients receiving upadacitinib 15 mg once-daily achieve a satisfactory humoral response to pneumococcal 13-valent conjugate (PCV-13) vaccine, despite receiving concomitant methotrexate (MTX).It is well known that a weakened immune response, comorbidities and immunosuppressant drug therapy all contribute to an increased susceptibility to infections in patients with RA. Likewise, the morbidity and mo...

Predefined analysis of FUTURE 5, the largest Phase 3 randomised trial of secukinumab in patients with PsA to date, demonstrates that secukinumab results in early, statistically significant, clinically meaningful, sustained improvements in PROs across all doses, compared with placebo.The fully human anti-interleukin 17A monoclonal antibody, secukinumab has shown clinical and radiographical efficacy in patients with PsA, yet the clinical significance of improvements across a wide variety of PROs r...
Baricitinib reduces structural damage progression versus placebo with background MTX and/or MTX, even in patients with moderate or high disease activity.In patients with RA, TNFi, IL-6i and rituximab have been shown to uncouple the link between disease activity and radiographic progression such that patients are protected from structural damage progression even if remission/low disease activity is not achieved.As such, Lopez-Romero, et al. aimed to evaluate if baricitinib further enhances diseas...
Upadacitinib continues to show consistently better clinical responses, compared with adalimumab, through 3 years, including rates of remission and low disease activity, physical function and pain severity.Following the favourable upadacitinib efficacy data seen in the SELECT-COMPARE study at 72 weeks, Fleischmann, et al. assessed the long-term safety and efficacy of upadacitinib versus adalimumab over 3 years in the long-term extension of this study, with promising results. ...
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...

Janus kinase-targeting therapies in rheumatology: a mechanisms-based approach

Nat Rev Rheumatol. 2022 Jan 5:1–13. Epub ahead of print doi: 10.1038/s41584-021-00726-8

The development of targeted small-molecule therapies such as JAK inhibitors, which have varied selective inhibitory profiles, has enabled a paradigm shift in the treatment of diverse disorders, to the extent that they could ultimately enable either complete withdrawal or avoidance of glucocorticoid use in some autoimmune diseases, and could have the potential to regulate any active factor inhibiting the transition to cure.In this review paper, Tanaka, et al. describe the progress in JAK-targetin...

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...
