Identification of novel off targets of baricitinib and tofacitinib by machine learning with a focus on thrombosis and viral infection

Sci Rep. 2022 doi: 10.1038/s41598-022-11879-1

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.

Unincreased risk of hospitalized infection under targeted therapies versus methotrexate in elderly patients with rheumatoid arthritis: a retrospective cohort study

Arthritis Res Ther. 2022 doi: 10.1186/s13075-022-02807-9

Retrospective, longitudinal, population-based study shows that despite an overall higher incidence of hospitalised infection (HI) in both elderly and older elderly patients compared to young patients, the risks of HI in patients exposed to targeted therapy versus MTX is not significantly increased.

Comparison of drug retention of TNF inhibitors, other biologics and JAK inhibitors in RA patients who discontinued JAK inhibitor therapy

Rheumatology (Oxford) 2022 doi: 10.1093/rheumatology/keac285

Real-world population-based study shows that a switch to a second JAKinib results in a higher drug retention, as compared to switching to a TNFi, in patients with RA who discontinue original JAKinib therapy.

Impact of filgotinib on sacroiliac joint magnetic resonance imaging structural lesions at 12 weeks in patients with active ankylosing spondylitis (TORTUGA trial)

Rheumatology 2022;61:2063–71 doi:10.1093/rheumatology/keab543

Maksymowych et al., carried out a post-hoc analysis to assess the effect of filgotinib on MRI measures of structural change in the SI joint in patients with active AS in the TORTUGA trial. This study evaluated lesions using SPARCC SSS definitions for erosion, backfill, fat metaplasia and ankylosis by two independent scoring readers.

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.

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.

Safety Profile of Upadacitinib up to 3 Years in Psoriatic Arthritis: An Integrated Analysis of Two Pivotal Phase 3 Trials

Rheumatol Ther. 2022 doi: 10.1007/s40744-021-00410-z

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

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...
