Do Allergic Comorbidities Alter the Efficacy and Safety of Abrocitinib or Dupilumab in Patients with Moderate-to-Severe Atopic Dermatitis?

Allergic comorbidities are common in patients with atopic dermatitis (AD). Individual trials with abrocitinib or dupilumab demonstrated efficacy and safety in patients with moderate-to-severe AD and allergic comorbidities. This post hoc analysis of the phase 3 JADE COMPARE and DARE trials compared efficacy, safety, and quality of life following abrocitinib and dupilumab treatment in adults with moderate-to-severe AD, with or without comorbid asthma, allergic rhinitis, or food allergy. Data were pooled from patients who received abrocitinib (200 mg/day) or dupilumab (300 mg/every 2 weeks) for 16 weeks with concomitant topical therapy. Assessments by self-reported asthma, allergic rhinitis, or food allergy included the proportion of patients achieving Investigator's Global Assessment of clear or almost clear (IGA 0/1), ≥ 75% improvement in Eczema Area and Severity Index (EASI-75), ≥ 4-point improvement in Peak Pruritus Numerical Rating Scale (PP-NRS4), least squares mean change from baseline in Dermatology Life Quality Index (DLQI) and SCORing Atopic Dermatitis (SCORAD), and safety. Of 1195 patients (abrocitinib, n = 588; dupilumab, n = 607), 377 (32%), 225 (19%), and 211 (18%) patients self-reported comorbid asthma, food allergy, or allergic rhinitis, respectively. Week 16 IGA 0/1 responses were comparable between patients with/without comorbidity with abrocitinib (52%/54% [with/without asthma], 50%/54% [with/without allergic rhinitis], and 53%/53% [with/without food allergy]) or dupilumab (42%/42%, 37%/43%, and 47%/41%). EASI-75 and PP-NRS4 responses and DLQI and SCORAD improvements were also comparable between patients with/without comorbidity in each treatment arm. Treatment-emergent adverse events were more common in patients with comorbidities in the abrocitinib (76%/67% [with/without asthma], 80%/67% [with/without allergic rhinitis], and 78%/67% [with/without food allergy]) and dupilumab (71%/53%, 71%/57%, and 62%/59%) arms. Abrocitinib and dupilumab improved AD signs and symptoms with a manageable safety profile in patients with moderate-to-severe AD, regardless of asthma, allergic rhinitis, or food allergy.
