Ruxolitinib Cream in Participants With Facial and/or Neck Atopic Dermatitis Involvement

The EASI scoring system examines 4 areas of the body (head/neck, trunk, upper limbs, and lower limbs) and weights them for participants of at least 8 years of age. Each of the 4 body regions is assessed separately for erythema (E), induration/papulation/edema (I), excoriations (Ex), and lichenification (l) on a scale of 0 to 3 (0 = none, absent; 1 = mild; 2 = moderate; 3 = severe). Half scores are allowed between severities 1, 2, and 3. The final EASI score was obtained by weight-averaging these 4 scores and will range from 0 to 72; the severity strata are as follows: 0 = clear; 0.1 to 1.0 = almost clear; 1.1 to 7.0 = mild; 7.1 to 21.0 = moderate; 21.1 to 50.0 = severe; 50.1 to 72.0 = very severe. Specifically for the head and neck region, the EASI score ranges from 0 to 7.2 An EASI75 responder was defined as a participant achieving a 75% or greater improvement from Baseline in the EASI score for the head and neck.

Time frame: Baseline; Week 4

Population: Full Analysis Population: all participants enrolled in the study who had at least 1 application of study drug. Missing post-Baseline values were imputed as Non-Responders at Week 4. The 95% confidence interval for the difference was computed based on a large-sample normal approximation with continuity correction.

A TEAE was defined as any AE either reported for the first time or the worsening of a pre-existing event after the first application of the study drug. An AE was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not it was considered drug related. The severity of AEs was graded using the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 (Grades 1 to 5). Grade 1: mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2: moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental activities of daily living (ADL). Grade 3: severe or medically significant but not immediately life threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care ADL. Grade 4: life-threatening consequences; urgent intervention indicated. Grade 5: death related to AE.

Time frame: up to approximately 4 weeks plus 30 days

A TEAE was defined as any adverse event (AE) either reported for the first time or the worsening of a pre-existing event after the first application of the study drug. An AE was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not it was considered drug related. An AE could therefore have been any unfavorable or unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study drug.

Time frame: Baseline; Weeks 2 and 8

Population: Full Analysis Population. Only participants with available data were analyzed. The 95% confidence interval for the difference was computed based on a large-sample normal approximation with continuity correction.
