Brief Summary
This multicenter study is being conducted to provide additional PF-06826647 safety and tolerability data, and to further explore the clinical efficacy of PF-06826647 in the treatment of moderate to severe plaque psoriasis. Additionally, the study is intended to enable selection of oral dose and dosing regimen for the future clinical development of PF-06826647.

Outcome Measures
Primary Outcomes (8)
Percentage of Participants With a Psoriasis Area and Severity Index 90 (PASI 90) Response Up to Week 16 - Investigational Treatment Period
The PASI quantifies the severity of a participant's psoriasis based on both lesion severity and the percentage of body surface area (BSA) affected. PASI is a composite scoring by the investigator of degree of erythema, induration, and scaling (each scored separately) for each of 4 body regions (head and neck, upper limbs, trunk \[including axillae and groin\], and lower limbs \[including buttocks\]), with adjustment for the percent of BSA involved for each body region and for the proportion of the body region to the whole body. The PASI score can vary in increments of 0.1 and range from 0.0 to 72.0, with higher scores representing greater severity of psoriasis. PASI 90 response was defined as at least a 90% reduction in PASI relative to baseline. The statistical analysis was for the data at Week 16.
Baseline up to Week 16
Number of Participants With Treatment-Emergent Adverse Events (All-Causality), Week 16 to Week 40 - Extension Treatment Period
An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. A serious AE (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. In this outcome measure, an AE was considered treatment-emergent if the event started on or after the first dosing day and time/start time but before the last dose plus the lag time.
From Week 16 to Week 40
Number of Participants With Treatment-Emergent Adverse Events (Treatment Related), Week 16 to Week 40 - Extension Treatment Period
Treatment-related adverse event (AE) was any untoward medical occurrence attributed to study drug in a participant who received study drug. Serious AE (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. In this outcome measure, an AE was considered treatment-emergent if the event started on or after the first dosing day and time/start time but before the last dose plus the lag time. Relatedness to investigational product (PF-06826647 or placebo) was assessed by the investigator (Yes/No). Participants with multiple occurrences of an AE within a category were counted once within the category.
From Week 16 to Week 40
Number of Participants With Laboratory Test Abnormality - Hematology (Normal Baseline), Week 16 to Week 40 - Extension Treatment Period
Following hematology parameters were analyzed for laboratory examination: hemoglobin (HGB), hematocrit, erythrocytes (Ery.), reticulocytes, Ery. mean corpuscular volume, Ery. mean corpuscular HGB, Ery. mean corpuscular HGB concentration, platelets, reticulocytes/erythrocytes, leukocytes, lymphocytes/leukocytes, neutrophils/leukocytes, basophils, basophils/leukocytes, eosinophils, eosinophils/leukocytes, monocytes, monocytes/leukocytes, activated partial thromboplastin time, prothrombin time, prothrombin international (Intl.) normalized ratio, neutrophils total count, and lymphocytes total count. LLN=lower limit of normal; ULN=upper limit of normal.
From Week 16 to Week 40
Number of Participants With Laboratory Test Abnormality - Chemistry (Normal Baseline), Week 16 to Week 40 - Extension Treatment Period
Following clinical chemistry parameters were analyzed for laboratory examination: bilirubin, direct bilirubin, indirect bilirubin, aspartate aminotransferase, alanine aminotransferase, gamma glutamyl transferase, alkaline phosphatase, protein, albumin, blood urea nitrogen, urea, creatinine, urate, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, sodium, potassium, chloride, calcium, bicarbonate, glucose, creatine kinase, and cholesterol.
From Week 16 to Week 40
Number of Participants With Laboratory Test Abnormality - Urinalysis (Normal Baseline), Week 16 to Week 40 - Extension Treatment Period
Following urinalysis parameters were analyzed for laboratory examination: urine pH, urine glucose, urine ketones, urine protein, urine hemoglobin, urine urobilinogen, urine bilirubin, urine nitrite, urine leukocyte esterase, urine erythrocytes, urine leukocytes, urine hyaline, and urine bacteria.
From Week 16 to Week 40
Number of Participants With Electrocardiogram (ECG) Data Meeting Pre-defined Criteria, Week 16 to Week 40 - Extension Treatment Period
Criteria for ECG abnormalities: maximum increase PR interval increase from baseline (IFB): percent change (Pctchg) \>=25 percent (%) for baseline value of \>200 milliseconds (msec) and Pctchg\>=50% for baseline value of \<=200 msec for PR interval, a maximum IFB: Pctchg\>=50%, maximum QTcF interval (Fridericia's Correction) of 450 msec to \<=480 msec, 480 msec to \<=500 msec and a maximum change of \<30 change =\<60 or \>60 msec from baseline.
From Week 16 to Week 40
Number of Participants With Vital Sign Data Meeting Pre-defined Criteria, Week 16 to Week 40 - Extension Treatment Period
The vital signs were obtained with participant in the seated position, after having sat calmly for at least 5 minutes. Criteria for vital signs abnormalities: sitting diastolic blood pressure (BP) \< 50 millimeter of mercury (mmHg), sitting diastolic BP change \>= 20 mmHg increase, sitting diastolic BP change \>= 20 mmHg decrease, sitting systolic BP \< 90 mmHg, sitting systolic BP change \>= 30 mmHg increase, and sitting systolic BP change \>= 30 mmHg decrease.
From Week 16 to Week 40
