Abrocitinib effect on patient‐reported outcomes in patients with moderate‐to‐severe atopic dermatitis: Results from phase 3 studies, including the long‐term extension <scp>JADE EXTEND</scp> study

This analysis includes patients from the phase 3 trials JADE MONO‐1 (NCT03349060), JADE MONO‐2 (NCT03575871) and JADE COMPARE (NCT03720470) who completed the full treatment period of placebo or abrocitinib (200 or 100 mg once daily) and subsequently entered JADE EXTEND and were randomised to receive once‐daily abrocitinib 200 or 100 mg. Patient‐reported endpoints to Week 48 included the proportion of patients who achieved Dermatology Life Quality Index (DLQI) scores of 0/1 (no effect of AD on quality of life [QoL]) and a ≥4‐point improvement in Patient‐Oriented Eczema Measure (POEM) score (clinically meaningful improvement). Data cut‐off: April 22, 2020.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Baseline DLQI mean scores were 15.4 and 15.3 in the abrocitinib 200‐ and 100‐mg groups, respectively, which corresponded to a ‘very large effect’ on QoL; at Week 48, mean DLQI scores were lower with abrocitinib 200 mg (4.6; ‘small effect’ on QoL) and abrocitinib 100 mg (5.9; ‘moderate effect’ on QoL). Baseline POEM mean scores were 20.4 and 20.5 in the abrocitinib 200‐ and 100‐mg groups, respectively; at Week 48, mean POEM scores were 8.2 and 11.0. Week 48 patient‐reported responses with abrocitinib 200 mg and abrocitinib 100 mg were 44% and 34% for DLQI 0/1, and 90% and 77% for a ≥4‐point reduction in POEM score.</jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p>In patients with moderate‐to‐severe AD, long‐term abrocitinib treatment resulted in clinically meaningful improvement in patient‐reported symptoms of AD, including QoL.</jats:p></jats:sec>
