- Child, Adult, Older adult
Study population: The study population eligible for enrollment includes adult and adolescent patients aged ≥12 years diagnosed with moderate to severe AD who receive at least one dose of abrocitinib.
This NI study will enroll 150 patients from approximately 15 sites across the US. The study population eligible for enrollment includes adult and adolescent patients aged ≥12 years diagnosed with moderate to severe AD who receive at least one dose of abrocitinib and satisfy the inclusion and exclusion criteria. Patients who had inadequate response or intolerance to previous ≤2 biologic therapies will be included in this study as there is a lack of effectiveness data for abrocitinib in these patients. As this will be an observational study, there will be no sampling and all patients that meet the inclusion and exclusion criteria will be recruited consequently. The study will be open for enrollment for approximately 12 months after the first patient has been enrolled. Regarding the inclusion and exclusion criteria, in the real-world setting recruitment may be slower than expected, thus depending on the observed enrollment rate, the enrollment period and number of sites may be reassessed and revised during the study.
9.2.1. Inclusion Criteria
Patients must meet all of the following inclusion criteria to be eligible for inclusion in the study:
- Participants who have chronic AD that has been present for ≥1 year before screening.
- Male and female patients aged >12 years at baseline.
- Patients with diagnosis of moderate-to-severe atopic dermatitis confirmed by a certified dermatologist, who are prescribed abrocitinib for use in accordance with the product label (USPI) and independently of the decision to enroll the patient in this study
- Patients who have inadequate responses or are intolerant to ≤2 previous biologic therapy approved for M2S AD. (Patients shall have had an inadequate response and/or intolerance to at least one, but no more than 2 biologic therapies approved for moderate-to-severe AD)
- Evidence of a personally signed and dated informed consent document indicating that the patient (or a legally acceptable representative) has been informed of all pertinent aspects of the study. Following receipt of oral and written information about the study, the adolescent (depending on local institutional review board/independent ethics committee requirements) must provide assent, and one or both (according to local regulations) parents or guardians of the child must provide signed informed consent before any study-related activity is carried out.
- Patients, who in the opinion of the investigator, are willing and able to comply with regular clinic visits as per standard practice at the site and agree to complete PRO questionnaires and other patient completed questions.
9.2.2. Exclusion Criteria
Patients meeting any of the following criteria will not be included in the study:
- Patients, that currently have active forms of other inflammatory skin diseases, other than AD or have evidence of skin conditions (eg, psoriasis, seborrheic dermatitis, Lupus) at the time of Day 1 that would interfere with evaluation of atopic dermatitis or response to treatment.
- Patients previously treated with abrocitinib or other oral/systemic JAK inhibitors
- Investigator site staff or Pfizer employees directly involved in the conduct of the study, site staff otherwise supervised by the investigator, and their respective family.
- Patient eligibility should be reviewed, documented, and confirmed by an appropriately qualified member of the investigator's study team before patients are enrolled in the study.

What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of patients achieving EASI-75 improvement from baseline at Week 16 after index date
EASI evaluates severity of participant's AD (excluded scalp, palms, soles) based on severity of AD clinical signs and % of body surface area (BSA) affected. Severity of clinical signs of AD (erythema, induration/papulation, excoriation and lichenification) scored separately for each of 4 body regions(head and neck, upper limbs, trunk [including axillae and groin] and lower limbs [including buttocks]) on4-point scale: 0= absent; 1= mild; 2= moderate; 3= severe. EASI area score was based upon % BSA with AD in each 4 body region: 0 (0%), 1 (>0 to <10%), 2 (10 to <30%), 3 (30 to <50%), 4 (50 to <70%), 5 (70 to <90%) and 6 (90 to 100%). Total EASI score =0.1*Ah*(Eh+Ih+Exh+Lh) + 0.2*Au*(Eu+Iu+ExU+Lu) + 0.3*At*(Et+It+Ext+Lt) + 0.4*Al*(El+Il+Exl+Ll); A = EASI area score; E = erythema; I = induration/papulation; Ex = excoriation; L = lichenification; h = head and neck; u = upper limbs; t = trunk; l = lower limbs. Total EASI score ranged from 0.0 to 72.0, higher scores = greater severity of AD
Measured: Baseline, week 16
Percentage of patients achieving ≥ 4-point improvement in Peak Pruritus Numerical Rating Scale (PP-NRS) collected daily all through the study from baseline at Week 2 by e-diary assessment
The severity of itch (pruritus) due to AD was assessed using a horizontal NRS. Participants at specified time points were asked the following question: "How would you rate your itch due to AD at the worst moment during the previous 24 hours?" The scale ranged from 0-10, where 0= no itch and 10= worst itch imaginable. Higher scores indicated worse itch.
Measured: Baseline, week 2
Secondary outcomes (20)
Percentage of patients achieving EASI-75, 90 and 100 from baseline at Week 4 and 16 after index date
EASI evaluates severity of participant's AD (excluded scalp, palms, soles) based on severity of AD clinical signs and % of body surface area (BSA) affected. Severity of clinical signs of AD (erythema, induration/papulation, excoriation and lichenification) scored separately for each of 4 body regions(head and neck, upper limbs, trunk [including axillae and groin] and lower limbs [including buttocks]) on4-point scale: 0= absent; 1= mild; 2= moderate; 3= severe. EASI area score was based upon % BSA with AD in each 4 body region: 0 (0%), 1 (>0 to <10%), 2 (10 to <30%), 3 (30 to <50%), 4 (50 to <70%), 5 (70 to <90%) and 6 (90 to 100%). Total EASI score =0.1*Ah*(Eh+Ih+Exh+Lh) + 0.2*Au*(Eu+Iu+ExU+Lu) + 0.3*At*(Et+It+Ext+Lt) + 0.4*Al*(El+Il+Exl+Ll); A = EASI area score; E = erythema; I = induration/papulation; Ex = excoriation; L = lichenification; h = head and neck; u = upper limbs; t = trunk; l = lower limbs. Total EASI score ranged from 0.0 to 72.0, higher scores = greater severity of AD
Measured: Baseline, week 4, week 16
Percentage of patients achieving v-IGA response of Clear (0) or Almost Clear (1) and ≥ 2 points improvement from baseline at Week 4 and 16 after index date
Validated IGA assesses severity of participant's AD on a 5 point scale. 0= clear, no inflammatory signs of AD; 1= almost clear, AD not fully cleared- light pink residual lesions (except post-inflammatory hyperpigmentation), just perceptible erythema, papulation/induration lichenification, excoriation, and no oozing/crusting; 2= mild AD with light red lesions, slight but definite erythema, papulation/induration, lichenification, excoriation and no oozing/crusting; 3= moderate AD with red lesions, moderate erythema, papulation/induration, lichenification, excoriation and slight oozing/crusting and 4= severe AD with deep dark red lesions, severe erythema, papulation/induration, lichenification, excoriation and moderate to severe oozing/crusting. Higher scores indicating more severity of AD. Assessment excluded soles, palms and scalp.
Measured: Baseline, week 4, week 16
Change from baseline in total percentage of BSA at week 4 and 16
4 body regions were evaluated: head and neck, upper limbs, trunk (including axillae and groin) and lower limbs (including buttocks). Scalp, palms and soles were excluded. BSA was calculated using handprint method. Number of handprints (size of participant's full palmer hand) fitting in the affected area of a body region was estimated. Maximum number of handprints were 10 for head and neck, 20 for upper limbs, 30 for trunk and 40 for lower limbs. Surface area of body region equivalent to 1 handprint: 1 handprint was equal to 10% for head and neck, 5% for upper limbs, 3.33% for trunk and 2.5% for lower limbs. Percent BSA for a body region was calculated as = total number of handprints in a body region * % surface area equivalent to 1 handprint. Overall % BSA for an individual: arithmetic mean of % BSA of all 4 body regions, ranged from 0 to 100%, with higher values representing greater severity of AD
Measured: Baseline, week 4, week 16
Percentage of patients achieving Peak Pruritus Numerical Rating Scale (PP-NRS) of 0 or 1 collected daily all through the study at Wk 4, 12 and 16
The severity of itch (pruritus) due to AD was assessed using a horizontal NRS. Participants at specified time points were asked the following question: "How would you rate your itch due to AD at the worst moment during the previous 24 hours?" The scale ranged from 0-10, where 0= no itch and 10= worst itch imaginable. Higher scores indicated worse itch.
Measured: Baseline, week 4, 12 and 16
Percentage of patients achieving PP-NRS-4 at week 2, 4, 12 and 16 from baseline.

Change from baseline in Medical Outcomes Study - Sleep Scale (MOS-Sleep Scale) at Wk 4, 12 and 16
The MOS Sleep Scale is a 12-item measure that is segregated into subscales addressing seven sleep domains (i.e. sleep disturbance, snoring, short of breath or headache, adequacy of sleep, somnolence, sleep problems index I and sleep problems index II). An additional single item assessed quantity of sleep. Each of the sleep domains were scored on a range of 0 to 100, and higher scores indicated worse outcomes. The quantity of sleep scores ranged from 0 to 24 (number of hours slept). Change from baseline scores for each individual sleep domain and quantity of sleep are reported in this outcome measure.
Measured: Baseline, week 4, 12 and 16
Percentage of Participants with an ADCT Total Score Reduction ≥ 5 from baseline at week 4, 12 and 16
The ADCT is a validated, brief and easily scored tool for use in clinical practice and clinical research to evaluate 6 symptoms and effects associated with AD over the past week.
Measured: Baseline, week 4, 12 and 16
Percentage of Participants Achieving Improvement (reduction) in DLQI/CDLQI of ≥ 4 points vs baseline at week 4, 12 and 16
CDLQI is a 10-item questionnaire that measures the impact of skin disease on adolescents (aged 12-17 years) quality of life over the last week. 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. CDLQI total score was the sum of individual scores of question 1-10 and ranges from 0 (not at all) to 30 (very much). Higher scores indicated more impact on quality of life of children. DLQI is the adult version of the same index.
