Dupilumab Improves AD Affecting the Hands, Feet

TOPLINE:

Dupilumab improved the signs and symptoms and quality of life in adults and adolescents with moderate to severe atopic hand and foot dermatitis compared with placebo.

METHODOLOGY:

• The multinational phase 3 LIBERTY-AD-HAFT trial of adults and adolescents with moderate to severe chronic atopic dermatitis (AD) of the hands, feet, or both included 67 participants at 48 sites randomized to dupilumab monotherapy and 66 to placebo.
• The primary endpoint was the proportion of patients scoring 0 or 1 on Hand and Foot Investigator’s Global Assessment (HF-IGA) at week 16.
• Secondary endpoints were severity and extent of signs, symptom intensity (itch and pain), sleep, and quality of life.

TAKEAWAY:

• At week 16, 27 patients receiving dupilumab vs 11 receiving placebo achieved an HF-IGA score of 0 or 1 (40.3% vs 16.7%; P = .003).
• At week 16, 35 participants receiving dupilumab vs nine receiving placebo improved at least four points in the weekly average of daily HF-Peak Pruritus Numeric Rating Scale (52.2% vs 13.6%; P < .0001).
• At week 16, Quality of Life Hand Eczema Questionnaire results improved in the dupilumab group compared with controls (P < .0001), and weekly average of daily Sleep Numeric Rating Scale results improved in the dupilumab group compared with controls (P < .05).
• The safety profile was similar to the known profile in adults and adolescents with moderate to severe AD.

IN PRACTICE:

The results of the study “support dupilumab” as an “efficacious systemic therapy for moderate to severe H/F AD,” the authors wrote.

SOURCE:

The study, led by Eric L. Simpson, MD, MCR, professor of dermatology at the Oregon Health & Science University in Portland, was published on January 29, 2024, in the Journal of the American Academy of Dermatology.

LIMITATIONS:

The short duration of the study and the large proportion of patients with positive patch tests (31 of 133) suggested that some participants may have had concurrent AD and allergic contact dermatitis, so the effect of dupilumab on those patients needs further evaluation.

DISCLOSURES:

The study was sponsored by Sanofi and Regeneron. All but one author had financial relationships with Sanofi, Regeneron, or both. Several authors were employees of, and may hold stocks or stock options in, Sanofi or Regeneron.
