Trial Outcomes & Findings for Pharmacokinetics Of CP-690,550 In Pediatric Patients With Juvenile Idiopathic Arthritis (JIA) (NCT NCT01513902)

NCT ID: NCT01513902

Last Updated: 2016-07-04

Results Overview

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 also influenced by the fraction of the dose absorbed. Clearance was estimated by non compartmental analysis (NCA) of PK data. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood. It was calculated by dividing the given oral dose by AUCtau. AUCtau is the area under the plasma concentration time-curve from time zero to end of dosing interval.

Population: The safety analysis population included all participants who received at least 1 dose of study drug.

An AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. A 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 AEs included both serious and non-serious AEs.

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.

Population: The analysis population was defined as all participants who had received at least 1 oral solution formulation of tofacitinib.

Participants were evaluated for taste assessment using a 5 categories questionnaire. Participants were asked to answer one of the following to describe the taste of oral solution of tofacitinib: Dislike very much, dislike a little, not sure, like a little, or like very much. The taste assessment was only performed for participants who received the oral solution. Number of participants within each category are reported.
