June 24, 2020 updated by: Pfizer

A PHASE 1, RANDOMIZED, DOUBLE-BLIND, VEHICLE AND ACTIVE COMPARATOR-CONTROLLED, PSORIASIS PLAQUE TEST STUDY TO ASSESS SAFETY, TOLERABILITY, AND PSORIATIC SKIN INFILTRATE THICKNESS FOLLOWING REPEATED, TOPICAL DOSES OF PF-06763809 SOLUTION IN SUBJECTS WITH MILD TO MODERATE CHRONIC PLAQUE PSORIASIS

The study is a randomized, double blinded, vehicle and active comparator controlled, multiple dose study in subjects with chronic plaque psoriasis. The study will have approximately 15 completers. Each subjects will receive three different topical doses of PF 06763809, PF 06763809 vehicle, and two active comparators. These will be applied to six different treatment fields for 18 days. The total duration of participation in the study will be approximately 7 weeks (minimum) to approximately 11 weeks (maximum), including the interval from Screening to the Follow up phone call visit.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Psoriatic Skin Infiltrate Thickness
Time Frame: Baseline, Days 7, 13 and 19
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.
Baseline, Days 7, 13 and 19
Number of Participants With Treatment-emergent Adverse Events (AEs)
Time Frame: Day 1 to Day 49
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.

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.
Day 1 to Day 49
Number of Participants With Post-Baseline Vital Signs Data Meeting Categorical Summarization Criteria
Time Frame: Day 1 to Day 49
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.
Day 1 to Day 49

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Area Under the Curve of the Psoriatic Skin Infiltrate Thickness
Time Frame: Day 1 to Day 19
Baseline was defined to be the measurement on Day 1. To evaluate the Area Under the Curve (AUC) of psoriatic skin infiltrate thickness/EPB for PF 06763809 compared to vehicle by mixed model analysis. The AUC of the psoriatic skin infiltrate thickness/EPB from Day 1 to Day 19 was determined using the linear trapezoidal rule. The log AUC was performed by the natural logarithm of the AUC of the psoriatic skin infiltrate thickness/EPB. 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.
Day 1 to Day 19
Change From Baseline in Skin Infiltrate Thickness in Response to PF-06763809 Compared to Calcipotriene/Calcipotriol Solution.
Time Frame: Baseline, Days 7, 13 and 19
The effect of PF-06763809 compared to calcipotriene/calcipotriol solution in the change of psoriatic skin infiltrate thickness/EPB both within and following 18 days of treatment. Baseline was defined to be the measurement on Day 1. 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.
Baseline, Days 7, 13 and 19
Change From Baseline in Skin Infiltrate Thickness in Response to PF-06763809 Compared to Betamethasone Solution.
Time Frame: Baseline, Days 7, 13 and 19
The effect of PF-06763809 compared to betamethasone solution in the change of psoriatic skin infiltrate thickness/EPB both within and following 18 days of treatment.
