Study Evaluating Effects of Multiple-Dose Administration of Itraconazole on the Single Dose Pharmacokinetics of Conjugated Estrogens/Bazedoxifene in Non-Obese and Obese Postmenopausal Women (CE/BZA)
March 23, 2015 updated by: Pfizer
A Phase 1, Open Label, Two Period, Fixed Sequence, Parallel Group Study To Estimate The Effects Of Multiple Dose Administration Of Itraconazole On The Single Dose Pharmacokinetics Of Conjugated Estrogens/Bazedoxifene In Non Obese (Bmi <30 Kg/m2) And Obese (Bmi ≥30 Kg/m2) Postmenopausal Women
This study will assess if itraconazole will affect the blood levels of Duavee when they are given together.
This study will also assess if a subject's body size affects the blood levels of Duavee.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - inf)] for BZA, total estrone adjusted for baseline and total equilin.
Time Frame: up to 96 hours
|
AUC (0 - inf)= Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - inf).
It is obtained from AUC (0 - t) plus AUC (t - inf).
|
up to 96 hours
|
Maximum Observed Plasma Concentration (Cmax) for BZA, total estrone adjusted for baseline and total equilin.
Time Frame: up to 96 hours
|
up to 96 hours
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - inf)] for unconjugated estrone, unconjugated estrone adjusted for baseline, total estrone, and unconjugated equilin.
Time Frame: up to 96 hours
|
AUC (0 - inf)= Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - inf).
It is obtained from AUC (0 - t) plus AUC (t - inf).
|
up to 96 hours
|
Maximum Observed Plasma Concentration (Cmax) for unconjugated estrone, unconjugated estrone adjusted for baseline, total estrone, and unconjugated equilin.
Time Frame: up to 96 hours
|
up to 96 hours
|
|
Apparent Oral Clearance (CL/F) for all analytes.
Time Frame: up to 96 hours
|
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.
|
up to 96 hours
|
Time to Reach Maximum Observed Plasma Concentration (Tmax) for all analytes.
Time Frame: up to 96 hours
|
up to 96 hours
|
|
Apparent Volume of Distribution (Vz/F) for all analytes.
Time Frame: up to 96 hours
|
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.
|
up to 96 hours
|
Terminal Phase Elimination Half-Life (t1/2) for all analytes.
Time Frame: up to 96 hours
|
Terminal Phase Elimination Half-Life is the time measured for the plasma concentration to decrease by one half.
|
up to 96 hours
