A Study Of The Safety, Tolerability, And Pharmacokinetics Of Multiple Doses Of PF-05180999 In Healthy Adults
22. maj 2014 opdateret af: Pfizer
A Phase I, Placebo Controlled, Randomized, Subject-And Investigator-Blind, Sponsor-Open, Multiple Ascending Dose Study To Evaluate The Safety, Tolerability, And Pharmacokinetics Of PF-05180999 In Healthy Adult Volunteers
PF-05180999 is a novel phosphodiesterase-2 (PDE2) inhibitor.
The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics of multiple doses of PF-05180999 administered twice daily over 14 days.
Exploratory measures of PDE2 inhibition will also be evaluated in blood and blister fluid.

Apparent Oral Clearance (CL/F)
Tidsramme: 0-48 hours post-final dose on 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.
Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

0-48 hours post-final dose on Day 14
|
|
Apparent Volume of Distribution (Vz/F)
Tidsramme: 0-48 hours post-final dose on 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.
