BACKGROUND: Facial-predominant inflammatory dermatoses are diagnostically heterogeneous and may overlap with atopic dermatitis (AD), contact dermatitis, rosacea-like inflammation, and autoimmune mimics. Stapokibart, an IL-4Rα-targeted monoclonal antibody, has demonstrated efficacy in moderate-to-severe AD, but real-world experience in facial-predominant AD-like presentations remains limited.
METHODS: We retrospectively reviewed five unpublished patients with facial-predominant inflammatory dermatoses treated with stapokibart in routine practice. Clinical phenotype, diagnostic work-up, prior and concomitant therapy, dosing, symptom scores, treatment course, recurrence, and adverse events were summarized descriptively. The cohort was not intended as a diagnostically uniform efficacy population, and no formal hypothesis testing was performed.
RESULTS: Five women aged 28-75 years were included. Pruritus numerical rating scale changed from a median of 3 (range, 2-4) at baseline to 1 (range, 0-3) at first follow-up; four patients improved and one worsened. All three patients with a well-supported facial-predominant AD phenotype showed rapid improvement in facial lesions and pruritus after stapokibart. One of these patients developed an injection-site reaction that led to treatment discontinuation; no serious adverse events were observed. One patient initially treated for AD-like facial dermatitis was subsequently evaluated for possible early clinically amyopathic dermatomyositis after telangiectatic and mildly atrophic features became more apparent. Another patient with an incompletely characterized AD-like facial eruption worsened on day 2 after stapokibart.
CONCLUSION: In this small case series, rapid improvement was observed in all three patients with a well-supported facial-predominant AD phenotype, whereas atypical or incompletely characterized eruptions showed greater diagnostic complexity and variable outcomes. These preliminary observations support further investigation of stapokibart in facial-predominant AD while underscoring the need for careful phenotyping before IL-4Rα blockade.
