Significant skin clearance demonstrated in 3 pivotal trials1

18+ years
≥75% improvement in lesion extent and severity (EASI-75) sustained at 1 year (secondary endpoint)2,3,a-c

CHRONOS: Concomitant
Therapy With TCS

Significant improvement in lesion extent and severity was also demonstrated with DUPIXENT in monotherapy trials1,4

51%
of adults treated with DUPIXENT (n=224) achieved ≥75% improvement in lesion extent and severity (EASI-75; secondary endpoint) vs 15% with placebo at Week 16 in SOLO 1 (n=224; P<0.001)
44%
of adults treated with DUPIXENT (n=233) achieved ≥75% improvement in lesion extent and severity (EASI-75; secondary endpoint) vs 12% with placebo at Week 16 in SOLO 2 (n=236; P<0.001)

EASI results across body regions at 1 year

CHRONOS 18+ years
Improvement in lesion extent and severity (EASI) from baseline measured across body regions in adults at Week 52 (post hoc analysis)2,5,a,b

CHRONOS: Concomitant
Therapy With TCS

Results at Week 16 (LSM change in EASI score from baseline; post hoc analysis)2

Head and neck:

72% for DUPIXENT + TCS
(n=104);
35% for placebo
+ TCS (n=304)

Upper extremities:

74% for DUPIXENT + TCS
(n=104);
40% for placebo
+ TCS (n=304)

Trunk:

79% for DUPIXENT + TCS
(n=104);
44% for placebo +
TCS (n=304)

Lower extremities:

77% for DUPIXENT +
TCS (n=104);
41% for
placebo + TCS (n=304)

Definitive conclusions cannot be made for these results at Week 16 and Week 52, as this was a post hoc analysis. Data were not multiplicity-controlled and P values were nominal.5

aIn the primary analyses of the efficacy endpoints, subjects who received rescue treatment or with missing data were considered nonresponders.1

bFull Analysis Set includes all subjects randomized.1

cIn CHRONOS, as needed, subjects received topical calcineurin inhibitors for problem areas only, such as the face, neck, and intertriginous and genital areas.1

dWeek 52 data were limited to patients completing 52 weeks as of the cutoff date.2

Measuring the extent and severity of lesional signs of atopic dermatitis

EASI combines the severity of the signs of eczema and the extent of skin involvement.6

The severity of each of 4 eczema signs is assessed on a scale of 0 to 36

The extent of lesions in each body region is evaluated based on the percentage of involvement and is given a value between 0 and 6. Each body region value is then weighted by a corresponding multiplier; lower extremities are weighted more while head and neck are weighted the least.6,7

Each region gets a total region score:

Severity Score x Area Score x Multiplier = Region Score

The final EASI score is the sum of all 4 region scores. The composite score, on a scale from 0 to 72, determines the severity of the signs of eczema and the extent to which the patient is affected.6,7,e

An improvement of at least 75% in lesion extent and severity (EASI-75) from baseline is a clinically meaningful change.1

eIn patients <8 years of age, the multipliers for the head and neck are 0.2, the trunk is 0.3, the upper extremities are 0.2, and the lower extremities are 0.3. In patients ≥8 years of age, the multipliers for the head and neck are 0.1, the trunk is 0.3, the upper extremities are 0.2, and the lower extremities are 0.4.6
