NCT ID: NCT02804399

Last Updated: 2019-01-25

Results Overview

AUCinf is the plasma area under the plasma concentration-time profile from time 0 extrapolated to infinite time. The pharmacokinetics (PK) parameter analysis population was defined as all participants enrolled and treated who have at least 1 of the PF-06463922 PK parameters of primary interest in at least 1 treatment period.

PF-06463922 100 mg Single Dose (SD)
PF-06463922 was administered following an overnight fast of at least 10 hours at approximately 0800 hours (plus or minus 2 hours) as 4 \* 25 milligram (mg) tablets on Day 1 of Period 1. Investigator site personnel administered study medication with ambient temperature water to a total volume of approximately 240 milliliter (mL).
Rifampin 600 Once a Day (QD) + PF-06463922 100 mg SD
Rifampin 600 mg once daily was administered 1 hour before or 2 hours after a meal from Day 1 to Day 9 of Period 2, except for rifampin dose on Day 8 of Period 2, which was administered simultaneously with PF-06463922. PF-06463922 100 mg (4 \* 25 mg tablets) and rifampin were administered (rifampin followed by PF-06463922) following an overnight fast of at least 10 hours at approximately 0800 hours (plus or minus 2 hours).

OTHER_PRE_SPECIFIED outcome

Timeframe: Baseline to about 18 days after the first PF-06463922 dose.

Population: All participants who received PF-06463922, rifampin and PF-06463922 in Period 1 and 2, respectively. A washout period of at least 10 days between the 2 single PF-06463922 dose was maintained.

PR interval was the interval between the start of the P wave and the start of the QRS complex, corresponding to the time between the onset of the atrial depolarization and onset of ventricular depolarization. Criteria for potentially clinically important changes (chg) in ECG were defined as: absolute values of PR interval \>=200 to \<220 msec, \>=220 to \<240 msec, \>=240 to \<260 msec and \>=260 msec. Increase from baseline \>=40, \<60, \>=60 and \<80, \>=80, and relative change from baseline \>25%. The beginning of the Q wave to the end of the T wave corresponding to electrical systole (QT) interval corrected using the Fridericia formular (QTCF) of 450 to \<480 msec, 480 to \<500 msec and \>=500 msec, or an increase of 30 to \<60 msec of \>=60 msec. Maximum is abbreviated as Max.

Population: All participants who received PF-06463922, rifampin and PF-06463922 in Period 1 and 2, respectively. A washout period of at least 10 days between the 2 single PF-06463922 dose was maintained.

Participants abstained from all concomitant treatments, except for the treatment of adverse events. Limited use of non-prescription medications that were not believed to affect participant safety or the overall results of the study might be permitted on a case by case basis following approval by the sponsor. All participants were questioned about concomitant treatment at each clinic visit. Treatments taken within 28 days before the first dose of study investigational product were documented as a prior treatment. Treatment taken after the first dose of study investigational product were documented as concomitant treatments. Females taking hormone replacement therapy might be eligible to participate in this study if they were willing to discontinue therapy at least 28 days prior to the first dose of study treatment and remained off hormonal therapy for duration of the study. Clinical significance was judged by the investigator.

Timeframe: Baseline to about 18 days after the first PF-06463922 dose.

Population: All participants who received PF-06463922, rifampin and PF-06463922 in Period 1 and 2, respectively. A washout period of at least 10 days between the 2 single PF-06463922 dose was maintained.

An adverse event (AE) was any untoward medical occurrence in a clinical investigation participant administered a product or medical device; the event need not necessarily have a casual relationship with the treatment or usage. A serious adverse event (SAE) was any untoward medical occurrence at any dose that: 1) resulted in death; 2) was life threatening (immediate risk of death); 3) required inpatient hospitalization or prolongation of existing hospitalization; 4) resulted in persistent or significant disability/incapacity (substantial disruption of the ability to conduct normal life functions); 5) resulted in congenital anomaly/birth defect. TEAE included both non-serious adverse events and serious adverse events.
