According to the results reported on ClinicalTrials.gov, this trial (NCT04033367) looked at the use of dupilumab (an injectable medicine) in people with atopic dermatitis (eczema) who also had problems with sleep. A total of 188 participants took part — 127 received dupilumab from the start, and 61 received a placebo (an inactive dummy treatment). The trial had two phases: a 12-week "double-blind" period (where neither participants nor researchers knew who was getting which treatment), followed by a 12-week open-label extension where everyone received dupilumab. The main thing being measured was how much participants' sleep quality scores changed over the first 12 weeks. The reported data shows that, for the main measure — sleep quality rated on a scale of 0 (worst) to 10 (best) — the dupilumab group reported an average decrease of about 47.7% from their starting score, compared to a decrease of about 33.0% in the placebo group. For itch intensity (rated 0–10, with 10 being worst), the dupilumab group reported an average reduction of around 52.5%, compared to around 23.3% in the placebo group. The reported data also shows changes in an overall eczema severity score (called SCORAD, ranging 0–103): the dupilumab group showed an average decrease of about 37.8 points, compared to about 20.6 points in the placebo group. For the other reported measures, the dupilumab group showed an average reduction of 4.85 points in a sleep-loss rating (on a 0–10 scale), compared to 2.31 points in the placebo group. On a standardised sleep impairment questionnaire (where lower scores mean less impairment), the dupilumab group's score fell by an average of 11.42 points, compared to 7.77 points in the placebo group. Finally, for total nightly sleep time, the dupilumab group reported sleeping on average 9 minutes more per night by week 12, while the placebo group reported sleeping about 6.4 minutes less.
