Conditions
-----------------
Healthy

Intervention / Treatment
-----------------
* Drug: PF-02341066
* Drug: PF-02341066


Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: Healthy male and/or female of non-childbearing potential subjects between the ages of 18 and 55 years, inclusive (Healthy is defined as no clinically relevant abnormalities identified by a detailed medical history, full physical examination, including blood pressure and pulse rate measurement, 12-lead electrocardiogram(ECG) and clinical laboratory tests). Exclusion Criteria: Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing). Treatment with an investigational drug within 30 days (or as determined by the local requirement, whichever is longer) or 5 half-lives preceding the first dose of study medication. Pregnant or nursing females; females of childbearing potential, including those with tubal ligation. To be considered for enrollment, women of 45 to 55 years of age who are postmenopausal (defined as being amenorrheic for at least 2 years) must have confirmatory Follicle-stimulating hormone(FSH) test results at Screening.

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) | Area under the plasma concentration time-curve from zero (pre-dose) to the last measured concentration (AUClast). | 0 (pre-dose), 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 16, 24, 36, 48, 60, 72, 84 and 96 hours (hrs) post PF-02341066 dose in period 1 and additional 168 hrs post PF-02341066 dose in period 2 | 
| Area Under the Curve From Time Zero to Extrapolated Infinite Time (AUC [0 - ∞]) | AUC (0-∞) = Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0-∞). It is obtained from AUC (0-t) plus AUC (t-∞). | 0 (pre-dose), 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 16, 24, 36, 48, 60, 72, 84 and 96 hrs post PF-02341066 dose in period 1 and additional 168 hrs post PF-02341066 dose in period 2 | 
| Maximum Observed Plasma Concentration (Cmax) |  | 0 (pre-dose), 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 16, 24, 36, 48, 60, 72, 84 and 96 hrs post PF-02341066 dose in period 1 and additional 168 hrs post PF-02341066 dose in period 2 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time to Reach Maximum Observed Plasma Concentration (Tmax) |  | 0 (pre-dose), 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 16, 24, 36, 48, 60, 72, 84 and 96 hrs post PF-02341066 dose in period 1 and additional 168 hrs post PF-02341066 dose in period 2 | 
| Plasma Decay Half Life (t1/2) | Plasma decay half-life is the time measured for the plasma concentration to decrease by one half. | 0 (pre-dose), 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 16, 24, 36, 48, 60, 72, 84 and 96 hrs post PF-02341066 dose in period 1 and additional 168 hrs post PF-02341066 dose in period 2 | 
| Apparent Oral Clearance (CL/F) | Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the body. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. | 0 (pre-dose), 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 16, 24, 36, 48, 60, 72, 84 and 96 hrs post PF-02341066 dose in period 1 and additional 168 hrs post PF-02341066 dose in period 2 | 
| Apparent Volume of Distribution (Vz/F) | 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 blood concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed. | 0 (pre-dose), 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 16, 24, 36, 48, 60, 72, 84 and 96 hrs post PF-02341066 dose in period 1 and additional 168 hrs post PF-02341066 dose in period 2 |
