Recruitment details

At time of early termination,<40% of planned subjects were treated across treatment groups. Number of subjects enrolled up to early termination of study were insufficient to allow meaningful inference and robust statistical analyses of data. As a result, all safety data was summarized with Cohort 1 and 2 combined for crisaborole and vehicle groups.

Screening details

This study was originally plan to conduct in 2 different cohorts for crisaborole and vehicle groups. Cohort 1 was planned for eligible for TCS therapy (hydrocortisone butyrate cream 0.1%), and Cohort 2 was planned for subjects not eligible for TCS therapy but eligible for topical calcineurin inhibitor (TCI) therapy (pimecrolimus cream 1%).

Number of Subjects With Adverse Events (AEs), Serious Adverse Events (SAEs) and Treatment Discontinuations due to AEs and SAEs ^[2]

End point description

An AE is any untoward medical occurrence in a study subject administered a product or medical device; the event need not necessarily have a causal relationship with the treatment or usage. TEAEs are events between the first dose of study drug up to 28 days after last dose that were absent before treatment or that worsened relative to pretreatment state. A SAE is any untoward medical occurrence at any dose that: results in death; is life-threatening (immediate risk of death); requires inpatient hospitalisation or prolongation of existing hospitalisation; results in persistent or significant disability/incapacity (substantial disruption of the ability to conduct normal life functions); results in congenital anomaly/birth defect; or that is considered to be an important medical event. Safety analysis set (SAF) included all subjects who received at least one dose of the investigational product according to actual treatment received.

Change From Baseline in Percent Body Surface Area (%BSA) at Day 8, 15, 22 and 29

End point description

4 body regions were evaluated: head and neck, upper limbs, trunk (including axillae) and lower limbs (including buttocks) excluding scalp. BSA was calculated using handprint method. Number of handprints (size of subject’s full palmer hand) fitting in affected area of a body region was estimated. Maximum number of handprints were: 10 for head, neck (20 for <8 years age), 20 for upper limbs, 30 for trunk, 40 for lower limbs (30 for <8 years age). Surface area (SA) of body region equivalent to 1 handprint: 1 handprint=10% for head, neck (5% for <8 years age), 5% for upper limbs, 3.33% for trunk, 2.5% for lower limbs (3.33% for <8 years age). %BSA for a body region =total number of handprints in a body region * % SA equivalent to 1 handprint. % BSA for an individual: mean of % BSA of all 4 body regions, range=0-100%, higher values=greater AD severity.

Change From Baseline in Subject Reported Itch Severity Scale in Subjects Aged 6-11 Years at Day 8, 15, 22 and 29

End point description

The severity of itch (pruritus) due to AD was assessed using the five-category subject reported itch severity scale for subjects aged 6-11 years. Subjects at specified time points were asked to “circle the face that shows how itchy your skin has been today”. The scale ranged from 0 to 4, where 0= no itch and 4= very itch. Higher scores indicated worse itch. Data was not summarized as per SAP which was revised prior to the analyses and which reflect limitations related to reduced sample size (39% enrollment) of early terminated study. Smaller than originally planned sample size was insufficient to allow robust statistical analyses. Pruritus related PRO endpoints used different instruments in each of 3 age groups. As a result, subdividing population based on age group renders smaller sample size in pediatric groups, therefore data was not summarized.

DLQI is a 10-item questionnaire that measures the impact of skin disease on subjects aged >=16 years. Each question was evaluated on a 4-point scale ranging from 0 (not at all) to 3 (very much); where higher scores indicated more impact on quality of life. Scores from all 10 questions were added up to give DLQI total score range from 0 (not at all) to 30 (very much). Higher scores indicated more impact on quality of life of subject. Analysis was performed on all subjects aged >=16 years from FAS, and FAS included all randomised subjects who received at least 1 dose of investigational product. Here, ‘Number of Subjects Analysed’ signifies number of subjects evaluable for this endpoint and ‘Number Analysed (n)’ signifies number of subjects evaluable for each specified timepoint.

End point description

The CDLQI was a 10-item questionnaire that measures the impact of skin disease on children's (aged 4 to 15 years) quality of life. Each question was evaluated on a 4-point scale ranging from 0 (not at all) to 3 (very much); where higher scores indicate more impact on quality of life. The CDLQI total score was the sum of individual scores of question 1-10 and ranged from 0 (not at all) to 30 (very much): 0-1 = no effect on the child's life; 2-6 = small effect; 7-12 = moderate effect; 13-18 = very large effect; 19-30 = extremely large effect. Higher scores indicated more impact on quality of life of children. Analysis was performed on all subjects aged 4 to 15 years from FAS, and FAS included all randomised subjects who received at least 1 dose of investigational product.

End point title

Change From Baseline in Dermatitis Family Impact Questionnaire (DFI) in Subjects Aged 2-17 Years at Day 8, 15, 22 and 29

End point description

The DFI was a 10-item disease questionnaire that measures the impact of having a child (aged 2-17 years) with AD on family quality of life. It was completed by parent/legal guardian of the child (affected by AD), based on recall over the past week. Each question was scored on a 4-point scale ranging from 0 (not at all) to 30 (very much): where higher scores indicated worst quality of life of family. The DFI total score was the sum of individual scores of the 10 questions and ranges from 0 (no impact on life of family) to 30 (maximum effect on life of family), where higher DFI scores indicated maximum effect on life of family. Analysis was performed on all subjects 2 to 17 years from FAS, and FAS included all randomised subjects who received at least 1 dose of investigational product. Here, ‘Number of Subjects Analysed’ signifies number of subjects evaluable for this endpoint and ‘Number Analysed (n)’ signifies number of subjects evaluable for each specified timepoint.
