Upadacitinib 15 mg once daily demonstrated a similar safety profile to adalimumab 40 mg every other week, except for higher rates of HZ and opportunistic infections with upadacitinib treatment in patients treated for PsA

Two Phase 3 Trials of Baricitinib for Alopecia Areata

N Engl J Med. 2022. Epub ahead of print doi: 10.1056/NEJMoa2110343

Phase 3 trials in patients with severe alopecia areata show that baricitinib is superior to placebo with respect to hair regrowth at 36 weeks.
Alopecia areata is characterised by nonscarring hair loss that can affect any hair-bearing site. Although mild cases of this emotionally- and psychosocially-distressing autoimmune disease may resolve within 12 months, more severe forms of the disease are unlikely to remit without treatment.

A Retrospective Study of the Efficacy of JAK Inhibitors or Abatacept on Rheumatoid Arthritis-Interstitial Lung Disease

Inflammopharmacology. 2022. Epub ahead of print doi: 10.1007/s10787-022-00936-w

This study of the effectiveness of JAKinibs or abatacept in patients with RA-interstitial lung disease (RA-ILD) shows that treatment is related to stability or improvement of RA-ILD in over 80% of patients.

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...

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.

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...
