Improvement in lesion extent and severity compared to placebo at 16 weeks2–4

DUPIXENT was studied in a Phase 3 clinical trial in adolescents with moderate-to-severe atopic dermatitis (AD) as a monotherapy for up to 16 weeks2–4

Efficacy as monotherapy compared to placebo4

AD-1526: Proportion of adolescent patients achieving EASI-75 at Week 16*2

At 16 weeks, 42% of patients on DUPIXENT achieved ≥75% improvement in lesion extent and severity (EASI-75) compared to 8% of patients on placebo2

AD-1526: Proportion of adolescent patients achieving IGA 0 or 1 at Week 16†3,4

At 16 weeks, 24% of patients on DUPIXENT achieved an IGA score of 0 or 1 with a reduction of ≥2 points on a 0–4 IGA scale compared to 2% of patients on placebo3,4

AD-1526: Proportion of adolescent patients achieving EASI-50 at Week 16*3

At 16 weeks, 61% of patients on DUPIXENT achieved ≥50% improvement in lesion extent and severity (EASI-50) compared to 13% of patients on placebo3

AD-1526: Proportion of adolescent patients achieving EASI-90 at Week 16*3

At 16 weeks, 23% of patients on DUPIXENT achieved ≥90% improvement in lesion extent and severity (EASI-90) compared to 2% of patients on placebo3

Visible results demonstrated in adolescent patients at Week 16 with DUPIXENT monotherapy5,6

Baseline

Week 16

Baseline

Week 16

Responder:

achieved at least a 75% improvement in lesion extent and severity (EASI score) and an IGA score of 0 or 1 with a reduction of ≥2 points on a 0–4 IGA scale

Baseline

Week 16

Non-responder:

did not achieve at least a 75% improvement in lesion extent and severity (EASI score) or an IGA score of 0 or 1 with a reduction of ≥2 points on a 0–4 IGA scale

Clinical photographs are actual patients treated with DUPIXENT in the AD-1526 adolescent trial and are used with patient consent. Individual results may vary.

AD-1526: A randomised, placebo-controlled, double-blind, parallel-group, multicentre, Phase 3 trial of adolescent patients (n=251) with moderate-to-severe AD whose disease was inadequately controlled by topical treatment, randomised to receive either a) 200/300 mg DUPIXENT Q2W (n=82) (licensed dose), b) 300 mg DUPIXENT Q4W (n=84) or c) placebo Q2W for 16 weeks.4


The co-primary endpoints were the proportion of patients with both IGA 0/1 (clear/almost clear) and the proportion of patients achieving 75% improvement in EASI (EASI-75) from baseline to Week 16.3,4


The key secondary endpoints were the percentage change in EASI from baseline to Week 16, the percentage change in peak pruritus NRS score from baseline, proportion of patients with ≥3-point improvement in peak pruritus NRS score from baseline to Week 16, proportion of patients with ≥4-point improvement in peak pruritus NRS score from baseline to Week 16.4


Other secondary endpoints were the proportion of patients achieving at least 50% improvement in EASI (EASI-50), change from baseline in percent body surface area affected (BSA) by AD, percentage change from baseline in SCORing Atopic Dermatitis (SCORAD), and changes from baseline in Children’s Dermatology Life Quality Index (a clinically meaningful improvement in CDLQI is defined as a ≥6-point improvement on a 0–13 scale), Patient-Oriented Eczema Measure (POEM) and SCORAD sleep loss scores from baseline to Week 16.4


*An EASI score is based on a clinician’s weighted score (0 to 72) of four affected areas grading the physical signs of AD (erythema, oedema/papulation, excoriation, lichenification)7,8
An IGA score is based on the clinician’s impression of a patients AD based on severity of erythema, infiltration, papulation and oozing/crusting.9


AD, atopic dermatitis; BSA, body surface area; EASI, Eczema Area and Severity Index; IGA, Investigator’s Global Assessment; TCS, topical corticosteroids.
