Detailed Description

This is a randomized, double blind, placebo controlled, parallel group, Phase 3 study to evaluate the efficacy and safety of PF 04965842 in adolescent participants 12 to <18 years of age with moderate to severe AD. Participants will be screened within 28 days prior to the first dose of study intervention to confirm study eligibility. Subjects must have moderate-severe AD involving at least 10% Body Surface Area (BSA); an Investigator Global Assessment (IGA) score of at least 3; an Eczema Area Severity Index (EASI) of at least 16 and Peak Pruritus Numerical Rating Score (NRS) of at least 4 on baseline/Day 1. Eligible subjects will be randomized at the Baseline/Day 1 visit. Approximately 225 participants will be randomized in a 1:1:1 ratio to receive once daily PF 04965842 at 200 mg, 100 mg, or placebo for 12 weeks. Randomization will be stratified by baseline disease severity (moderate [IGA = 3] vs. severe [IGA = 4] AD). The investigational products will be administered QD for 12 weeks. Background therapy (medicated and non-medicated topical therapy) must be applied BID for the duration of the treatment period. The co-primary efficacy endpoints are an IGA score of clear (0) or almost clear (1) with a reduction from baseline of greater than 2 points at Week 12 AND an at least 75% improvement of the EASI score (EASI-75) at week 12. Safety and efficacy assessments will be conducted at the investigator site by a clinical assessor blinded to treatment assignment. Scheduled clinic or telephone study visits for all subjects will occur at Screening, Baseline/Day 1, Day 8 (by phone), Day 15, Day 29, Day 43 (by phone), Day 57, Day 85 (End of treatment/Early termination), Day 113 (End of Study). Participants discontinuing early from the study will undergo a 4 week follow up period.

This study includes an immunogenicity sub study integrated into the last 4 weeks of the main study treatment period. At Week 8, up to approximately 90 participants (up to approximately 30 in each treatment arm) who have completed 8 weeks of treatment with study intervention will receive a tetanus, diphtheria and acellular pertussis combination vaccine (Tdap), and collection of blood samples for the evaluation of immunogenicity at Weeks 8 and 12. Participants of this sub study will complete all other protocol specified procedures in the main study.

At the end of the 12 week study treatment, qualified participants completing the study will have the option to enter the long term extension (LTE) study B7451015.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants Achieving Investigator's Global Assessment (IGA) Response of 'Clear' (0) or 'Almost Clear' (1) and ≥2 Points Improvement From Baseline at Week 12
Time Frame: Baseline to Week 12
The IGA of Atopic Dermatitis (AD) was scored on a 5-point scale (0-4), reflecting a global consideration of the erythema, induration and scaling. The overall severity of AD was assessed according to the 5-point scale: 0=Clear, 1=Almost Clear, 2=Mild, 3=Moderate, and 4=Severe. Participants who withdrew from the study were counted as non-responder.
Baseline to Week 12
Percentage of Participants Achieving Eczema Area and Severity Index (EASI) Response ≥ 75% Improvement From Baseline at Week 12
Time Frame: Baseline to Week 12
The EASI quantifies the severity of AD based on both severity of lesion clinical signs and the percent of body surface area (BSA) affected. The EASI score can vary in increments of 0.1 and range from 0.0 to 72.0, with higher scores representing greater severity of AD. Participants who withdrew from the study were counted as non-responder.
Baseline to Week 12

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants Achieving ≥4 Points Improvement From Baseline in Peak Pruritis Numeric Rating Scale (PP-NRS) for Severity of Pruritus at Weeks 2, 4 and 12
Time Frame: Baseline, Weeks 2, 4 and 12
PP-NRS assesses the severity of itch (pruritus) due to AD. Participants were asked to assess their worst itching due to AD on an NRS anchored by the terms "no itch" (0) and "worst itch imaginable" (10). Participants who withdrew from the study were counted as non-responder.
Baseline, Weeks 2, 4 and 12
Change From Baseline in Pruritus and Symptoms Assessment for Atopic Dermatitis (PSAAD) at Week 12
Time Frame: Baseline to Week 12
The PSAAD is a daily patient reported symptom diary presented as a 15 item questionnaire that includes 11 items developed to measure symptoms of AD, along with 4 additional items for exploratory and psychometric validation purposes (Sleep & Usual Activities Questions and Patient Global Impression of Severity & Patient Global Impression of Change Questions). Participants answer each question about skin condition based on a 24 hour recall. Each question was evaluated on a 11-point scale ranging from 0 to 10, where higher scores indicate more impact on skin condition.The PSAAD total score is calculated as the average of the responses to each of the 11 items and ranges from 0 (none) to 10 (extreme), where higher scores indicate worse severity of AD symptoms.
Baseline to Week 12
Percentage of Participants Achieving IGA Response of 'Clear' or 'Almost Clear' and ≥2 Points Improvement From Baseline at All Scheduled Time Points Except Week 12
Time Frame: Baseline, Weeks 2, 4 and 8
The IGA of AD is scored on a 5-point scale (0-4), reflecting a global consideration of the erythema, induration and scaling. The overall severity of AD was assessed according to the 5-point scale: 0=Clear, 1=Almost Clear, 2=Mild, 3=Moderate, and 4=Severe. Participants who withdrew from the study were counted as non-responder.
Baseline, Weeks 2, 4 and 8
Percentage of Participants Achieving EASI Response ≥ 75% Improvement From Baseline at All Scheduled Time Points Except Week 12
Time Frame: Baseline, Weeks 2, 4 and 8
The EASI quantifies the severity of AD based on both severity of lesion clinical signs and the percent of BSA affected. The EASI score can vary in increments of 0.1 and range from 0.0 to 72.0, with higher scores representing greater severity of AD. Participants who withdrew from the study were counted as non-responder.
Baseline, Weeks 2, 4 and 8
Percentage of Participants Achieving EASI Response ≥ 50% Improvement From Baseline
Time Frame: Baseline, Weeks 2, 4, 8 and 12
The EASI quantifies the severity of AD based on both severity of lesion clinical signs and the percent of BSA affected. The EASI score can vary in increments of 0.1 and range from 0.0 to 72.0, with higher scores representing greater severity of AD. Participants who withdrew from the study were counted as non-responder.
Baseline, Weeks 2, 4, 8 and 12
Percentage of Participants Achieving EASI Response ≥ 90% Improvement From Baseline

Percentage of Participants Achieving Scoring Atopic Dermatitis (SCORAD) Response ≥ 50% Improvement From Baseline
Time Frame: Baseline, Weeks 2, 4, 8 and 12
SCORAD is a validated scoring index for AD,which combines extent (0-100),severity (0-18),and subjective symptoms (0-20) based on pruritus and sleep loss,each scored (0-10). Extent,denoted as A,is measured by BSA affected by AD as a percentage of the whole BSA.The score for each body region is added up to determine A (maximum of 100).Severity, denoted as B,consists of the severity of several signs.Each is assessed as none(0),mild(1),moderate(2) or severe(3).The severity scores are added together to give B (maximum of 18).Subjective symptoms,denoted as C,are each scored by the participant using a NRS where "0" is no itch (or no sleeplessness) and "10" is the worst imaginable itch (or sleeplessness).These scores are added to give 'C' (maximum of 20).SCORAD for an individual is calculated by the formula: A/5 + 7B/2 + C (can range from 0 to 103).Higher values of SCORAD represent worse outcome.

Change From Baseline in Pediatric Functional Assessment of Chronic Illness Therapy Fatigue Scale (Peds-FACIT-F) at Week 12
Time Frame: Baseline to Week 12
The Functional Assessment of Chronic Illness Therapy Fatigue Scale (FACIT-F) is a 13-item questionnaire. Participants scored each item on a 5-point scale: 0 (none of the time) to 4 (all of the time). Larger the participant's response to the questions (with the exception of 2 negatively stated), greater was the participant's fatigue. For all questions, except for the 2 negatively stated ones, the code was reversed and a new score was calculated as (4 minus the participant's response). The sum of all responses resulted in the FACIT-F score for a total possible score of 0 (worse score) to 52 (better score), with higher scores representing better overall health status (less fatigue). Changes from baseline at Week 12 are presented below. Changes from baseline at other scheduled time points were not evaluated.

Fold Increase of Immunoglobulin G (IgG) Concentrations Against Specific Vaccine Antigens at 4 Weeks Post-Vaccination
Time Frame: 4 weeks post-vaccination with Tdap (Week 12)
The immunogenicity analysis was to evaluate the effect of abrocitinib on immunogenicity to a tetanus, diphtheria and pertussis combination vaccine (Tdap) vaccine in adolescent participants 12 to <18 years of age with moderate to severe AD. Participants who completed 8 weeks of treatment with study intervention received Tdap at Week 8, and had blood samples collected for the evaluation of immunogenicity to the vaccine at Weeks 8 and 12. The fold increase was defined as the ratio (post-vaccination: pre-vaccination) of concentration values. The geometric mean fold rise (GMFR) is presented below, and was calculated by first arithmetically averaging the logarithmically transformed ratio (post-vaccination: pre-vaccination) values, and then back transformation. A 95% CI for GMFR was constructed by back transformation of the CI for the logarithmically transformed GMFRs computed using the Student's t distribution.
