Abstract
- Background: Abrocitinib, an oral, once-daily Janus kinase 1-selective inhibitor, improved itch severity, sleep, and work productivity versus placebo in patients with moderate-to-severe atopic dermatitis. Objective: The aim of this study was to investigate relationships among itch, sleep, and work productivity in the phase III JADE MONO-2 clinical trial. Methods: A repeated-measures longitudinal model was used to examine relationships between itch (using the Peak Pruritus Numerical Rating Scale [PP-NRS] or Nighttime Itch Scale [NTIS]) and sleep disturbance/loss (using the Patient-Oriented Eczema Measure sleep item and SCORing AD Sleep Loss Visual Analog Scale) and, separately, between itch and work productivity (using the Work Productivity and Activity Impairment-Atopic Dermatitis Version 2.0 questionnaire). Mediation modelling was used to investigate the effect of treatment (abrocitinib vs placebo) on work impairment via improvements in itch and sleep. Results: The relationships between itch/sleep and itch/work productivity were approximately linear. PP-NRS scores of 0, 4–6, and 10 were associated with 0 days, 3–4 days, and 7 days per week of disturbed sleep, respectively. PP-NRS or NTIS scores of 0–1, 4–5, and 10 were associated with 0–10%, 20–30%, and >50% overall work impairment, respectively. Seventy-five percent of the effect of abrocitinib on reducing work impairment was indirectly mediated by improvement in itch, followed by sleep. Conclusion: These results quantitatively demonstrate that reducing itch severity is associated with improvements in sleep and work productivity. Empirical evidence for the mechanism of action of abrocitinib showed that itch severity is improved, which reduces sleep loss/sleep disruption and, in turn, improves work productivity. Clinical Trial Registration: NCT03575871 Plain Language Summary: Atopic dermatitis (AD), also called atopic eczema, is a common skin disease that is associated with itch and reduced quality of life. Abrocitinib, a recently approved medicine for AD, was shown in clinical trials to improve itch, which is considered the most bothersome symptom to people with AD. Abrocitinib also improved sleep outcomes and work productivity in people with moderate or severe AD. It is unknown if improvement in itch can lead to improvement in sleep and work productivity. We analyzed data from the JADE MONO-2 study, which included 391 people who received treatment with abrocitinib or placebo for 12 weeks. We used mathematical modelling to study relationships between itch and sleep or work productivity. We also wanted to study if the improvements in itch and sleep with abrocitinib treatment had an impact on work productivity. We found that a relationship existed between itch, sleep disturbance, and work impairment; as itch improved, so too did sleep disturbance and work impairment. When people were treated with abrocitinib, they experienced relief from itch, which improved sleep, which in turn reduced work productivity loss. Larger and longer studies are needed to confirm these results. This analysis further informs the expectations of patients with moderate or severe AD as it relates to progression of symptom relief after treatment with abrocitinib. [ABSTRACT FROM AUTHOR]
