- Primary Outcome Measures
Name Time Method Percent Change From Baseline in Eczema Area and Severity Index (EASI) Score at Week 16 Baseline and Week 16 The EASI is a tool to measure the severity of clinical signs and the percentage of affected body surface area (BSA) in patients with atopic dermatitis (AD). The EASI is a composite scoring system to evaluate the degree of erythema, induration/papulation, excoriation, and lichenification (each scored separately) for each of 4 body regions, with adjustment for the percentage of BSA involved for each body region and for the proportion of the body region to the whole body. EASI scores range from 0 to 72, with higher scores reflecting greater disease severity. Erythema, induration/papulation, excoriation, and lichenification are scored on a scale of 0 (absent) to 3 (severe) for each body region: head and neck, upper limbs (including the external axillae and hands), trunk (including the internal axillae and groin), and lower limbs (including the buttocks and feet). The extent of affected skin in each body region is scored on a scale of 0 (no involvement) to 6 (90% to 100% involvement).

The 10 questions cover the following topics: symptoms; embarrassment; interference with shopping and home care, clothing choices, social and leisure activities, sports participation, work or study, close relationships, and sex; and treatment. Each question is scored from 0 to 3 ("not at all," "a little," "a lot," and "very much," respectively), giving a total score ranging from 0 to 30. A high score is indicative of a poor quality of life.

Patients were asked to respond to questions on frequency of sleep loss and skin dryness, itching, flaking, cracking, bleeding, and weeping over the past week. All answers carry equal weight, with a total possible score ranging from 0 to 28. A high score is indicative of a poor quality of life.

Patients were asked the following question in their local language: how would you rate your sleep last night? On a scale of 0 to 10, with 0 being "no sleep loss related to signs/symptoms of AD" and 10 being "I cannot sleep at all because of the signs/symptoms of AD". Higher scores indicate worse outcomes.
