The adverse event will be described and categorized as Treatment-emergent, Serious, abnormal in vital signals, and abnormal in laboratory parameters. Incidence and Severity of

mRNA Levels of CCL5 gene expression in skin biopsies quantified by normalized Ct values obtained by quantitative real-time PCR assay, measured at baseline, week 24 and week 48. Changes are characterized by differences in Ct values from a specific time point (week 24 or week 48) to baseline.

mRNA Levels of CXCR3(TGFB1) gene expression in skin biopsies quantified by normalized Ct values obtained by quantitative real-time PCR assay, measured at baseline, week 24 and week 48. Changes are characterized by differences in Ct values from a specific time point (week 24 or week 48) to baseline.

ACR 20 was calculated as a ≥20% improvement in tender and swollen joint counts and ≥20% improvement in 3 of the 5 remaining ACR core set measures: patient pain assessment (a horizontal visual analog scale assessment of the patient's level of pain), patient global assessment (the patient's overall assessment of how the arthritis was doing by a visual analog scale), physician global assessment (a horizontal visual analog scale measure of the physician's assessment of the patient's current disease activity), patient self-assessed disability (a validated and reliable patient self-assessment instrument which measured physical functions in rheumatoid arthritis patients) and an acute-phase reactant (C-reactive protein level). The participants receiving placebo in the initial period (Day 1 - Week 16) were combined into a single placebo group, while those who received PF-06700841 (10 mg QD) in the initial period were combined into a single PF-06700841 10 mg QD group.

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.

SRI-4 components included Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K), British Isles Lupus Assessment Group (BILAG) 2004 and Physician's Global Assessment (PhGA). Participants were classified as SRI-4 responders, if they met all of the following criteria compared with baseline: 1) greater than or equal to (\>=) 4 point reduction in SLEDAI-2K score; 2) no new BILAG A organ domain score or 2 new BILAG B organ domain scores; 3) no worsening (less than \[\<\] 0.3 point increase) in PhGA score. SLEDAI-2K: assesses improvement in disease activity (range: 0 to 105; higher score = higher severity). BILAG: assesses disease extent, severity in individual organ system (range: A \[severe\] to E \[no disease\]; higher score = less severity). PhGA: assesses worsening in participant's general health status (range: 0 \[none\] to 3 \[severe\]; higher score = higher severity).

The Psoriasis Area and Severity Index (PASI) score (0-72, with higher score representing greater severity) is a measurement of the severity and extent of psoriasis. The four regions of the body parts are head (10%), arms (20%), trunk (30%) and legs (40%). In each region, the area is expressed as a score of 0 (nothing), 1 (1-9%), 2 (10-29%), 3 (30-49%), 4 (50-69%), 5 (70-89%) or 6 (90-100%). Within each area, the degree of severity for erythema, induration and scaling are estimated between 0 and 4, with 4 being the highest severity. The final score combines disease severity and effected body surface area (BSA) from for four regions using the formula PASI =0.1Ah(Eh + Ih + Sh) + 0.2Au(Eu + Iu + Su) + 0.3At(Et + It + St) + 0.4Al(El + Il + Sl) where A = Area Score; E = erythema; I =induration; S = scaling; h = head; u = upper limbs; t = trunk; l = lower limbs.

The Mayo score is a tool designed to measure disease activity for ulcerative colitis. The Mayo scoring system ranges from 0 to 12 points and consists of 4 subscores, which are stool frequency, rectal bleeding, findings on endoscopy and physician's global assessment. Each subscore graded 0 to 3 with the higher score indicates more severe disease activity and lower score denotes improvement of disease activity as measured by the total Mayo score.

AUCinf = Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0-inf). It is obtained from AUC (0-t) plus AUC (t-inf).

Cmax is the maximum observed plasma concentration of PF-06700841 within 72 hours post dose, which was observed directly from the plasma concentration-time data.

AUCinf was area under the concentration-time curve from time 0 to infinity, which was calculated for PF-06700841 from the concentration-time data.

Skin irritation grade is defined as following: no reaction (-); slight erythema (+-); erythema (+); erythema + edema, papules (++); erythema + edema + papules + vesicles (small blisters) (+++) ; large blisters (++++)

QTc change from baseline at geometric mean of maximum concentrations observed after single doses of 200 mg PF-06700841 and maximum concentrations expected at lower doses of 30 and 60 mg.

An AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. AEs were classified according to the severity in 3 categories a) mild - AEs does not interfere with participant's usual function b) moderate - AEs interferes to some extent with participant's usual function c) severe - AEs interferes significantly with participant's usual function.
