Safety, Tolerability And Efficacy Study Of Topical PF-06763809 In Subjects With Mild To Moderate Chronic Plaque Psoriasis

Change From Baseline in Psoriatic Skin Infiltrate Thickness

Baseline was defined to be the measurement on Day 1. MMRM analysis of changes in psoriatic skin in psoriatic skin infiltrate thickness/echo poor band (EPB) in response to PF-06763809 2.3%, 0.8% and 0.23% applied topically for 18 consecutive days as compared to the vehicle control. Number of participants analyzed signifies number of participants who were evaluable for this outcome measure. Number analyzed refers to number of participants evaluable for specified rows of categories.

Time frame: Baseline, Days 7, 13 and 19

Number of Participants With Treatment-emergent Adverse Events (AEs)

Baseline was defined to be the measurement on Day 1. An AE was any untoward medical occurrence in a clinical investigation patient administered a product or medical device. Treatment-emergent AEs were those with initial onset or increasing in severity after the first dose of investigational product.

Time frame: Day 1 to Day 49

Number of Participants With Laboratory Test Abnormalities (Without Regard to Baseline Abnormality)

Baseline was defined to be the measurement on Day 1. The safety laboratory tests including Hematology, Clinical Chemistry and Urinalysis were performed. Hematology evaluation included: hemoglobin (HGB) (gram per decilitre=g/dL), hematocrit, erythrocytes (Ery.), Ery. Mean Corpuscular Volume, Ery. Mean Corpuscular Hemoglobin, Ery. Mean Corpuscular HGB Concentration (picograms per cell=pg/cell), platelets, leukocytes, lymphocytes, and neutrophils. Clinical chemistry evaluation included: bilirubin, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, protein, albumin, urea nitrogen, urea, creatinine, urate, sodium, potassium, chloride, calcium, bicarbonate, creatine kinase, and glucose. Urinalysis evaluation included: pH, urine glucose, ketones, urine protein, urine hemoglobin, urobilinogen, urine bilirubin, nitrite, and leukocyte esterase. LLN=lower limit of normal, ULN=upper limit of normal.

Time frame: Day 1 to Day 49

Number of Participants With Electrocardiogram (ECG) Data Meeting Pre-specified Criteria

Baseline was defined to be the measurement on Day 1. ECG categorical summarization criteria: 1) PR interval (Value\>=300 milliseconds \[msec\], %Change \[Chg\]\>=25/50%); 2) QRS interval (Value\>=140 msec, \>=50% change from baseline; 2) PR interval (the interval between the start of the P wave and the start of the QRS complex, corresponding to the time between the onset of the atrial depolarization and onset of ventricular depolarization): \>=300 msec, \>=25% change when baseline is \> 200 msec or \>=50% change when baseline is less than or equal to (\<=) 200 msec; 3) QT interval (time from ECG Q wave to the end of the T wave corresponding to electrical systole): absolute value of \>=500 msec; 4) QTc interval (QT corrected for heart rate): absolute value of 450 to \<480 msec, 480 to \<500 msec, \>=500 msec; a change from baseline of 30 to \<60 msec or \>=60 msec. The corrected QT interval by Fredericia=QTcF Interval.

Time frame: Day 1 to Day 49

Number of Participants With Post-Baseline Vital Signs Data Meeting Categorical Summarization Criteria

Baseline was defined to be the measurement on Day 1. Vital Signs including diastolic blood pressure (DBP), pulse rate, and systolic blood pressure (SBP) were measured.

Time frame: Day 1 to Day 49
