Atopic dermatitis (AD) of the hands and/or feet is often chronic, difficult to treat and substantially impacts patient quality of life. This study aims to report the effect of dupilumab treatment on signs, symptoms and quality of life in patients with atopic hand and foot dermatitis using dedicated clinical and patient reported instruments. The phase 3, randomized, double-blind LIBERTY-AD-HAFT (NCT04417894) trial enrolled patients ≥12 years with moderate-to-severe [Investigator’s Global Assessment (IGA) 3/4] atopic hand and foot dermatitis. Patients were randomized to dupilumab monotherapy 300 mg q2w in adults; 200/300 mg every 2 weeks in adolescents, or placebo for 16 weeks. The primary endpoint was hand and foot IGA 0/1 score at Week 16. Safety/tolerability was assessed. The 133 patients enrolled were randomized to dupilumab (n = 67) or placebo (n = 66). At Week 16, the primary and all secondary endpoints were met. Significantly more patients in the dupilumab vs. placebo group achieved hand and foot IGA 0/1 (40.3% vs. 16.7%; P = 0.003; primary endpoint) and ≥4-point improvement in the hand and foot Peak Pruritus Numerical Rating Scale (52.2% vs. 13.6%; P < 0.0001; a key secondary endpoint). Dupilumab-treated patients experienced significant improvement in percent change from baseline in the modified Total Lesion Sign Score for hand and foot lesions vs. placebo [LS mean (SE) −69.4 (5.8) vs. −31.0 (5.9); P < 0.0001] and Hand Eczema Severity Index [HECSI; LS mean (SE) −74.8 (6.3) vs. −39.9 (6.2); P < 0.0001]. At Week 16, treatment with dupilumab also significantly increased the proportion of patients achieving a 75% improvement in HECSI (46.9% vs. 21.5%; P = 0.0028) and improved Quality of Life in Hand Eczema Questionnaire scores [LS mean (SE) −40.3 (4.0) vs. −16.2 (4.2); P < 0.0001]. The most common TEAEs (≥10%) were nasopharyngitis (16% vs. 11%) and dermatitis atopic (5% vs. 18%). Dupilumab significantly improved signs, symptoms and quality of life in patients with moderate-to-severe atopic hand and foot dermatitis and had an acceptable safety profile.
