    Abstract:
    BACKGROUND: The heterogeneous course of moderate-to-severe atopic dermatitis necessitates treatment flexibility. OBJECTIVE: We evaluated the maintenance of abrocitinib-induced response with continuous abrocitinib treatment, dose reduction or withdrawal, and response to treatment reintroduction following flare (JAK1 Atopic Dermatitis Efficacy and Safety [JADE] REGIMEN: National Clinical Trial 03627767). METHODS: Patients with moderate-to-severe atopic dermatitis responding to open-label abrocitinib 200 mg monotherapy for 12 weeks were randomly assigned in a 1:1:1 ratio to blinded abrocitinib (200 or 100 mg) or placebo for 40 weeks. Patients experiencing flare received rescue treatment (abrocitinib 200 mg plus topical therapy). RESULTS: Of 1233 patients, 798 responders to induction (64.7%) were randomly assigned. The flare probability during maintenance was 18.9%, 42.6%, and 80.9% with abrocitinib 200 mg, abrocitinib 100 mg, and placebo, respectively. Among patients with flare in the abrocitinib 200 mg, abrocitinib 100 mg, and placebo groups, 36.6%, 58.8%, and 81.6% regained investigator global assessment 0/1 response, respectively, and 55.0%, 74.5%, and 91.8% regained eczema area and severity index response, respectively, with rescue treatment. During maintenance, 63.2% and 54.0% of patients receiving abrocitinib 200 and 100 mg, respectively, experienced adverse events. LIMITATIONS: The definition of protocol-defined flare was not established, limiting the generalizability of findings. CONCLUSION: Induction treatment with abrocitinib was effective; most responders continuing abrocitinib did not flare. Rescue treatment with abrocitinib plus topical therapy effectively recaptured response.
