July 15, 2014 updated by: Pfizer

A Phase 1, Randomized, Third-Party Open, Placebo-Controlled, Multiple Dose Escalation, Parallel Group Study To Evaluate Local Tolerability, Safety And Pharmacokinetics Of Topically Applied PF-06263276 In Healthy Subjects

PF-06263276 is a first in class inhibitor of the Janus kinase (JAK) enzymes 1, 2, 3 and tyrosine kinase 2 (TYK2) that is being developed for the treatment of chronic plaque psoriasis. The goal of the study is to assess the safety, local tolerability, and pharmacokinetics in healthy subjects.

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
Draize toxicity assessment score.
Time Frame: Day 8, Day 28
Changes from baseline on Draize toxicity assessment score.
Day 8, Day 28
Changes from baseline vital signs (blood pressure, pulse rate, oral temperature and respiration rate) and physical examinations.
Time Frame: Day 23, Day 28
Day 23, Day 28
Changes from baseline in 12 lead electrocardiogram (ECG) parameters.
Time Frame: Day 23, Day 28
Quantitative changes in ECG intervals.
Day 23, Day 28
Incidence and severity of treatment emergent adverse events and withdrawals due to treatment emergent adverse events.
Time Frame: Day 23, Day 28
Day 23, Day 28
Incidence and magnitude of treatment emergent clinical laboratory abnormalities including hematology, chemistry, fasting glucose, urinalysis.
Time Frame: Day 23, Day 28
Day 23, Day 28

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
Cohorts 3 and 4: Maximum Observed Plasma Concentration (Cmax)
Time Frame: Day 1, Day 14
Day 1, Day 14
Cohorts 3 and 4: Time to Reach Maximum Observed Plasma Concentration (Tmax)
Time Frame: Day 1, Day 14
Day 1, Day 14
Cohorts 3 and 4: Area Under the Curve From Time Zero to 12 hours [AUC (0-12)]
Time Frame: Day 1, Day 14
AUC (0-t)= Area under the plasma concentration versus time curve from time zero (pre-dose) to time of last quantifiable concentration (0-t)
Day 1, Day 14
Cohorts 3 and 4: Dose-Normalized Area Under the Curve From Time Zero to 12 hours [AUC (0-12)]
Time Frame: Day 1, Day 14
AUC (0-t)= Area under the plasma concentration versus time curve from time zero (pre-dose) to time of last quantifiable concentration (0-t)
Day 1, Day 14
Cohorts 3 and 4: Dose-Normalized Maximum Observed Plasma Concentration [Cmax (dn)]
Time Frame: Day 1, Day 14
Day 1, Day 14
Cohorts 3 and 4: Plasma Decay Half-Life (t1/2)
Time Frame: Day 14
Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.
Day 14
Cohorts 3 and 4: Apparent Volume of Distribution (Vz/F)
Time Frame: Day 14
Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed.
Day 14
Cohorts 3 and 4: Apparent Oral Clearance (CL/F)
Time Frame: Day 14
Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Clearance was estimated from population pharmacokinetic (PK) modeling. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
