Brief Summary: B7451029 is a Phase 3 study to investigate PF-04965842 in adult patients who have moderate to severe atopic dermatitis and use background topical therapy. The efficacy of two dosage strengths of PF-04965842, 100 mg and 200 mg taken orally once daily will be evaluated relative to placebo over 12 weeks. The efficacy of the two dosage strengths of PF-04965842 will be compared with dupilumab in terms of pruritus relief at 2 weeks. The two dosage strengths of PF-04965842 and dupilumab 300 mg injected subcutaneously once every two weeks (with a loading dose of 600 mg injected on the first day) will also be evaluated relative to placebo over 16 weeks. The safety of the investigational products will be evaluated over the duration of the study. Subjects will use non-medicated emollient at least twice a day and medicated topical therapy such as corticosteroids, calcineurin inhibitors or PDE4 inhibitors, as per protocol guidance, to treat active lesions during the study. Subjects who are randomized to receive one of the two dosage strengths of PF-04965842 will also receive placebo injectable study drug every two weeks until Week 16 and then will continue on receiving only the oral study drug for 4 weeks. Subjects who are randomized to receive dupilumab injections every two weeks will also receive oral placebo to be taken once daily until Week 16 and will then continue to receive only the oral placebo for 4 weeks. Subjects who are randomized to the placebo arms, will receive both daily oral placebo and injectable placebo every two weeks until Week 16, after which they will receive either 100 mg or 200 mg of PF-04965842 taken orally once daily for 4 weeks, dependent upon which arm they have been allocated to. Eligible subjects will have an option to enter a long-term extension study after completing 20 weeks of treatment.

Percentage of Participants Achieving Eczema Area and Severity Index (EASI) Response >=75 Percent (%) Improvement From Baseline at Week 12	Baseline, Week 12	EASI evaluates severity of participants with 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 \[including buttocks\]) on 4-point scale: 0= absent; 1= mild; 2= moderate; 3= severe. EASI area score was based upon % BSA with AD in 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.
Percentage of Participants Achieving Investigator's Global Assessment (IGA) Response of Clear (0) or Almost Clear (1) and a Reduction of Greater Than or Equal to (>=) 2 Points From Baseline at Week 12	Baseline (the last measurement prior to first dosing on Day 1), Week 12	IGA assessed severity of atopic dermatitis (AD) on a 5 point scale (0 to 4, higher scores indicate more severity). Scores: 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; 4= severe AD with deep dark red lesions, severe erythema, papulation/induration, lichenification, excoriation and moderate to severe oozing/crusting.

Extent (A): rule of 9 was used to calculate BSA affected by AD as a % of whole BSA for each body region- head and neck 9%; upper limbs 9% each; lower limbs 18% each; anterior trunk 18%; back 18%; 1% for genitals. The score for each body region was added to determine A (0-100). Severity (B): severity of each sign (erythema; edema; oozing; excoriation; skin thickening; dryness) was assessed as none=0, mild=1, moderate=2,severe=3. The severity scores were summed to give B (0-18). Subjective symptoms (C): pruritus and sleep, each of these 2 were scored by participant/caregiver using visual analogue scale (VAS) where "0" = no itch/no sleeplessness and "10" = the worst imaginable itch/sleeplessness, higher scores=worse symptoms. Scores for itch and sleeplessness were added to give 'C' (0-20). The SCORAD for an individual was calculated: A/5 + 7\*B/2 + C; range from 0 to 103; higher values of SCORAD=worse outcome.

Participants rated their symptoms of AD over the past 24 hours, using 11 items (itchy skin, painful skin, dry skin, flaky skin, cracked skin, bumpy skin, red skin, discolored skin \[lighter or darker\], bleeding from skin, seeping or oozing fluid from skin \[other than blood\], and skin swelling). Participant had to think about all the areas of their body affected by their skin condition and chose the number that best described their experience for each of the 11 items, from 0 (no symptoms) to 10 (extreme symptoms), higher scores signified worse skin condition. Total PSAAD score = arithmetic mean of 11 items, 0 (no symptoms) to 10 (extreme symptoms), where higher score = worse skin condition.
HADS - Anxiety Scale at Week 20	Week 20	HADS: participant rated 14-item questionnaire. HADS consisted of 2 subscales: HADS-A scale and HADS-D scale, both of these subscales comprised of 7 items each. Each item was rated on a 4-point scale, score range from 0 to 3, where higher scores indicates more anxiety/depression symptoms. HADS-A assesses state of generalized anxiety (anxious mood, restlessness, anxious thoughts, panic attacks). HADS-D assesses state of lost interest and diminished pleasure response (lowering of hedonic tone). HADS-A: sum of all 7 items resulted in score range of 0 (no presence of anxiety) to 21 (severe feeling of anxiety); higher score indicating greater severity of anxiety.
Change From Baseline in Pruritus and Symptoms Assessment for Atopic Dermatitis (PSAAD) Total Score Week 1 to Week 16	Baseline, Week 1 to Week 16	PSAAD is a daily participant reported symptom electronic diary. Participants rated their symptoms of AD over the past 24 hours, using 11 items (itchy skin, painful skin, dry skin, flaky skin, cracked skin, bumpy skin, red skin, discolored skin \[lighter or darker\], bleeding from skin, seeping or oozing fluid from skin \[other than blood\], and skin swelling). Participant had to think about all the areas of their body affected by their skin condition and chose the number that best described their experience for each of the 11 items, from 0 (no symptoms) to 10 (extreme symptoms), higher scores signified worse skin condition. Total PSAAD score = arithmetic mean of 11 items, 0 (no symptoms) to 10 (extreme symptoms), where higher score = worse skin condition.
Change From Baseline in SCORAD Visual Analogue Scale (VAS) of Itch and Sleep Loss at Week 2, 4, 8 12 and 16	Baseline, Week 2, 4, 8 12 and 16	SCORAD: scoring index for AD combining extent, severity, subjective symptoms. Extent (A): rule of 9 was used to calculate BSA affected by AD as a % of whole BSA for each body region- head and neck 9%; upper limbs 9% each; lower limbs 18% each; anterior trunk 18%; back 18%; 1% for genitals. The score for each body region was added to determine A (0-100). Severity (B): severity of each sign (erythema; edema; oozing; excoriation; skin thickening; dryness) was assessed as none=0, mild=1, moderate=2,severe=3. The severity scores were summed to give B (0-18). Subjective symptoms (C): pruritus and sleep, each of these 2 were scored by participant/caregiver using visual analogue scale (VAS) where "0" = no itch/no sleeplessness and "10" = the worst imaginable itch/sleeplessness, higher scores=worse symptoms. Scores for itch and sleeplessness were added to give 'C' (0-20). The SCORAD for an individual was calculated: A/5 + 7\*B/2 + C; range from 0 to 103; higher values of SCORAD=worse outcome.
Change From Baseline in Patient-Oriented Eczema Measure (POEM) at Week 12 and 16	Baseline, Week 12 and 16	POEM is a 7-item participant reported outcome (PRO) measure used to assess the impact of AD (dryness, itching, flaking, cracking, sleep loss, bleeding and weeping) over the past week. Each item is scored as following: "no days (0)", "1-2 days (1)", "3-4 days (2)", "5-6 days (3)" and "every day (4)". The score ranges from 0 to 28, where higher score indicated greater severity.
Percentage of Participants With SCORAD Response >=75% Improvement From Baseline at Week 2, 4, 8 12 and 16	Baseline, Week 2, 4, 8 12 and 16	SCORAD: scoring index for AD combining extent, severity, subjective symptoms. Extent (A): rule of 9 was used to calculate BSA affected by AD as a % of whole BSA for each body region- head and neck 9%; upper limbs 9% each; lower limbs 18% each; anterior trunk 18%; back 18%; 1% for genitals. The score for each body region was added to determine A (0-100). Severity (B): severity of each sign (erythema; edema; oozing; excoriation; skin thickening; dryness) was assessed as none=0, mild=1, moderate=2,severe=3. The severity scores were summed to give B (0-18). Subjective symptoms (C): pruritus and sleep, each of these 2 were scored by participant/caregiver using visual analogue scale (VAS) where "0" = no itch/no sleeplessness and "10" = the worst imaginable itch/sleeplessness, higher scores=worse symptoms. Scores for itch and sleeplessness were added to give 'C' (0-20). The SCORAD for an individual was calculated: A/5 + 7\*B/2 + C; range from 0 to 103; higher values of SCORAD=worse outcome.
Least Square Mean of Number of Steroid-free Days From Baseline up to Week 16	Baseline up to Week 16	Number of days when a corticosteroid as a concomitant medication was not used up to Week 16 is reported as Least square mean in this outcome measure.
SCORAD VAS of Itch and Sleep Loss at Week 18 and 20	Week 18 and 20	SCORAD: scoring index for AD combining extent, severity, subjective symptoms. Extent (A): rule of 9 was used to calculate BSA affected by AD as a % of whole BSA for each body region- head and neck 9%; upper limbs 9% each; lower limbs 18% each; anterior trunk 18%; back 18%; 1% for genitals. The score for each body region was added to determine A (0-100). Severity (B): severity of each sign (erythema; edema; oozing; excoriation; skin thickening; dryness) was assessed as none=0, mild=1, moderate=2,severe=3. The severity scores were summed to give B (0-18). Subjective symptoms (C): pruritus and sleep, each of these 2 were scored by participant/caregiver using visual analogue scale (VAS) where "0" = no itch/no sleeplessness and "10" = the worst imaginable itch/sleeplessness, higher scores=worse symptoms. Scores for itch and sleeplessness were added to give 'C' (0-20). The SCORAD for an individual was calculated: A/5 + 7\*B/2 + C; range from 0 to 103; higher values of SCORAD=worse outcome.
