- Primary Outcome Measures
Name Time Method Number of Subjects With Treatment Emergent Treatment-Related Adverse Events (AEs) or other safety concerns Baseline (Day 1, hour 0) up to 28 days after last dose of study medication Assessment by adverse event monitoring, 12 lead ECGs, telemetry, vital signs and clinical safety laboratory measurements.
Treatment-related AE was any untoward medical occurrence attributed to study drug in a subject who received study drug. Serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to 28 days after last dose that were absent before treatment or that worsened relative to pretreatment state. Relatedness to Drug was assessed by the investigator (Yes/No). Subjects with multiple occurrences of an AE within a category were counted once within the category.
- Secondary Outcome Measures
Name Time Method Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0- infinity)] for PF-06667272 and PF-06818073 (as permitted) 0, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 24, 36, and 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-06667272 and PF-06818073 0, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 24, 36, and 48 hours post dose Maximum Observed Plasma Concentration (Cmax)
Time to Reach Maximum Observed Concentration for PF-06667272 and PF-06818073 0, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 24, 36, and 48 hours post dose Time to Reach Maximum Observed Plasma Concentration (Tmax)
Plasma Decay Half-Life (t1/2) for PF-06667272 and PF-06818073 0, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 24, 36, and 48 hours post dose Plasma Decay Half-Life (t1/2)
Apparent Total Body Clearance (CL/F) for PF-06667272 0, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 24, 36, and 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 apparent total body 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.
Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) for PF-06667272 and PF-06818073 0, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 24, 36, and 48 hours post dose Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast)
Apparent Volume of Distribution (Vz/F) for PF-06667272 0, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 24, 36, and 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.
