- Assessment of adverse events (AEs), clinical laboratory tests, vital signs (including blood pressure and pulse rate) and cardiac conduction intervals as assessed via 12-lead electrocardiogram (ECG). [ Time Frame: 0 to 72 hours post dose ]
- Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) for PF-06678552 [ Time Frame: 0, 0.5, 1, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 36, 48 hours post dose ]Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast)
- Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - infinity)] for PF-06678552 [ Time Frame: 0, 0.5, 1, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 36, 48 hours post dose ]AUC (0 - infinity)= Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - infinity). It is obtained from AUC (0 - t) plus AUC (t - infinity).
- Maximum Observed Plasma Concentration (Cmax) for for PF-06678552 [ Time Frame: 0, 0.5, 1, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 36, 48 hours post dose ]Maximum Observed Plasma Concentration (Cmax)
- Time to Reach Maximum Observed Plasma Concentration (Tmax) for PF-06678552 [ Time Frame: 0, 0.5, 1, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 36, 48 hours post dose ]Time to Reach Maximum Observed Plasma Concentration (Tmax)
- Plasma Decay Half-Life (t1/2) for PF-06678552 [ Time Frame: 0, 0.5, 1, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 36, 48 hours post dose ]Plasma Decay Half-Life (t1/2)
- Apparent Oral Clearance (CL/F) for PF-06678552 [ Time Frame: 0, 0.5, 1, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 36, 48 hours post dose ]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. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.
- Apparent Volume of Distribution (Vz/F) for PF-06678552 [ Time Frame: 0, 0.5, 1, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 36, 48 hours post dose ]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.
- Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) for PF-06644927 [ Time Frame: 0, 0.5, 1, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 36, 48 hours post dose ]Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast)
- Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - infinity)] for PF-06644927 [ Time Frame: 0, 0.5, 1, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 36, 48 hours post dose ]AUC (0 - infinity)= Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - infinity). It is obtained from AUC (0 - t) plus AUC (t - infinity).
- Maximum Observed Plasma Concentration (Cmax) for PF-06644927 [ Time Frame: 0, 0.5, 1, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 36, 48 hours post dose ]Maximum Observed Plasma Concentration (Cmax)
- Time to Reach Maximum Observed Plasma Concentration (Tmax) for PF-06644927 [ Time Frame: 0, 0.5, 1, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 36, 48 hours post dose ]Time to Reach Maximum Observed Plasma Concentration (Tmax)
- Plasma Decay Half-Life (t1/2) for PF-06644927 [ Time Frame: 0, 0.5, 1, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 36, 48 hours post dose ]Plasma Decay Half-Life (t1/2)
- Amount of PF-06644927 excreted in the urine (Ae) [ Time Frame: 0-4, 4-12, and 12-24 hours post dose ]Amount of drug excreted in the urine is a measure of the degree that the kidneys filter drug from the blood to the urine.
- Percent of PF-06678552 dose excreted in the urine as PF-06644927 (Ae%) [ Time Frame: 0-4, 4-12, and 12-24 hours post dose ]The percent of PF-06678552 dose excreted in the urine as PF-06644927 is calculated from the mass of dose excreted in the urine compared to the total dose of PF-06678552 and corrected for the relative weight of PF-06644927 to PF-06678552.
- Renal Clearance (CLr) for PF-06644927 [ Time Frame: 0-4, 4-12, and 12-24 hours post dose ]Renal clearance is the measure of the rate of drug moving into the urine from blood
