Dos Ensayos de fase 3 de baricitinib en 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.

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.

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...

Terapias dirigidas a la Janus quinasa en la reumatología: un enfoque basado en los mecanismos

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...
