Journal of the European Academy of Dermatology and Venereology : JEADV
BACKGROUND: Baricitinib demonstrated efficacy in treating adults with moderate-to-severe atopic dermatitis (AD) in Phase3 clinical trials. OBJECTIVE: To examine long-term efficacy of baricitinib combined with topical corticosteroids (TCS) in adult patients from a Phase3 study, BREEZE-AD7 (NCT03733301), enrolled in ongoing extension study, BREEZE-AD3 (NCT03334435). METHODS: Upon BREEZE-AD7 completion, responders or partial responders (RPR [vIGA-AD™ ≤2]) receiving baricitinib 2-mg or 4-mg + TCS, maintained their original treatment doses in BREEZE-AD3. Nonresponders (NR; vIGA-AD 3,4) receiving baricitinib 2-mg were rerandomized 1:1 to baricitinib 2-mg or 4-mg; NR receiving baricitinib 4-mg remained on same dose. Integrated data from all patients (RPR + NR = baricitinib 4-mg intent-to-treat [ITT] cohort) receiving continuous baricitinib 4-mg in BREEZE-AD7 through BREEZE-AD3 were analysed, along with baricitinib 4-mg or 2-mg RPR cohorts. Primary endpoint was proportion of patients with vIGA-AD (0,1) at Week16, 36, and 52 (Week32, 52, and 68 of continuous therapy). Additional outcomes included improvement in EASI75 and Itch NRS (up to Week32). Missing data were imputed by last observation carried forward. RESULTS: In baricitinib 4-mg ITT cohort (N=102), proportions of patients achieving vIGA-AD (0,1) at Week32, Week52, and Week68 were 21.6%, 26.5%, and 23.5%; EASI75 were 46.1%, 40.2%, and 43.1%, respectively. Itch NRS ≥4-point improvement (Itch≥4) were 47.3% at Week16 and 40.6% at Week32. In baricitinib 4-mg RPR cohort (N=63), proportions of patients achieving vIGA-AD (0,1) at Week32, Week52, and Week68 were 31.7%, 33.3%, 34.9%, respectively; EASI75 were 57.1%, 49.2%, and 49.2%, respectively. Itch≥4 were 53.6% at Week16 and 46.4% at Week32. Corresponding proportions for baricitinib 2-mg RPR cohort (N=53) for vIGA-AD (0,1) were 39.6%, 45.3% and 30.2%; EASI75 were 77.4%, 69.8% and 58.5%, respectively. Itch≥4 were 56.3% at Week16 and 47.9% at Week32. CONCLUSION: Baricitinib 4-mg and 2-mg combined with TCS maintained clinically meaningful sustained efficacy over 68 weeks of continuous treatment.
