Registration Number
NCT02065739
Lead Sponsor
Janssen Pharmaceutica N.V., Belgium
Brief Summary

The purpose of this study is to assess the effects of repeated administration of 200 mg of itraconazole on the single-dose pharmacokinetics of JNJ-42165279 in healthy male participants.

Detailed Description

This is an open-label (all people know the identity of the intervention), study in healthy male participants. This study will consist of a screening phase (between 21 and 2 days prior to the first dose administration of JNJ-42165279), a 2-period (Period 1: Day 1 to Day 3 and Period 2: Day 4 to Day 10) open-label treatment phase, and a follow-up phase (within 7 to 14 days after the last dose of JNJ-42165279). A single 30-mg dose of JNJ-42165279 will be administered on Day 1 of Period 1. During Period 2, the administration of oral itraconazole 200 mg once a day will start on Day 4. A second single oral 30-mg dose of JNJ-42165279 will be administered on Day 8 together with the dose of 200 mg itraconazole. Sixteen healthy participants will be enrolled in this study. Safety assessments will include assessment of adverse events, supine vital signs, 12-lead electrocardiogram, clinical laboratory testing and physical examinations. The maximum study duration for each participant will be approximately 7 weeks.

Primary Outcome Measures
NameTimeMethod
Maximum Observed Plasma Concentration (Cmax) of JNJ-42165279Day 1 (Pre-dose and post-dose 0.25, 0.50, 1, 1.5, 2, 2.5, 3, 4, 6, 9, 12, 16, hours), Day 2 (24, 36 hours), Day 3, Day 4, Day 8 (Pre-dose and post-dose 0.25, 0.50, 1, 1.5, 2, 2.5, 3, 4, 6, 9, 12, 16, hours), Day 9 (24, 36 hours), Day 10, and Day 11

The Cmax is defined as maximum observed analyte concentration.

Time to Reach Maximum Observed Plasma Concentration (Tmax) of JNJ-42165279Day 1 (Pre-dose and post-dose 0.25, 0.50, 1, 1.5, 2, 2.5, 3, 4, 6, 9, 12, 16, hours), Day 2 (24, 36 hours), Day 3, Day 4, Day 8 (Pre-dose and post-dose 0.25, 0.50, 1, 1.5, 2, 2.5, 3, 4, 6, 9, 12, 16, hours), Day 9 (24, 36 hours), Day 10, and Day 11

The Tmax is defined as actual sampling time to reach maximum observed analyte concentration.

Area Under the Plasma Concentration-Time Curve From Time Zero to Time at Last Observed Quantifiable Concentration (AUCt) of JNJ-42165279Day 1 (Pre-dose and post-dose 0.25, 0.50, 1, 1.5, 2, 2.5, 3, 4, 6, 9, 12, 16, hours), Day 2 (24, 36 hours), Day 3, Day 4, Day 8 (Pre-dose and post-dose 0.25, 0.50, 1, 1.5, 2, 2.5, 3, 4, 6, 9, 12, 16, hours), Day 9 (24, 36 hours), Day 10, and Day 11

AUCt is area under the plasma concentration-time curve from time zero to the last quantifiable concentration.

Area Under the Plasma Concentration-Time Curve From Time Zero to Infinite Time (AUC[0-infinity])of JNJ-42165279Day 1 (Pre-dose and post-dose 0.25, 0.50, 1, 1.5, 2, 2.5, 3, 4, 6, 9, 12, 16, hours), Day 2 (24, 36 hours), Day 3, Day 4, Day 8 (Pre-dose and post-dose 0.25, 0.50, 1, 1.5, 2, 2.5, 3, 4, 6, 9, 12, 16, hours), Day 9 (24, 36 hours), Day 10, and Day 11

The AUC(0-infinity) is area under the plasma concentration-time curve from time zero to infinite time, calculated as the sum of Area under Curve (AUC) last and C(last)/lambda(z), in which C(last) is the last observed quantifiable concentration.

Terminal Rate Constant (Lambda[z]) of JNJ-42165279Day 1 (Pre-dose and post-dose 0.25, 0.50, 1, 1.5, 2, 2.5, 3, 4, 6, 9, 12, 16, hours), Day 2 (24, 36 hours), Day 3, Day 4, Day 8 (Pre-dose and post-dose 0.25, 0.50, 1, 1.5, 2, 2.5, 3, 4, 6, 9, 12, 16, hours), Day 9 (24, 36 hours), Day 10, and Day 11

Lambda(z) is defined as terminal rate-constant which reflect the speed of drug elimination in vivo (within the living), and is estimated by log-linear regression analysis of the terminal phase of the plasma concentration versus time curve for at least 3 points.

Elimination Half-Life Period (T1/2) of JNJ-42165279Day 1 (Pre-dose and post-dose 0.25, 0.50, 1, 1.5, 2, 2.5, 3, 4, 6, 9, 12, 16, hours), Day 2 (24, 36 hours), Day 3, Day 4, Day 8 (Pre-dose and post-dose 0.25, 0.50, 1, 1.5, 2, 2.5, 3, 4, 6, 9, 12, 16, hours), Day 9 (24, 36 hours), Day 10, and Day 11

The Elimination Half-Life Period (T1/2) is the time measured for the plasma concentration to decrease by 1 half to its original concentration. It is associated with the terminal rate-constant (lambda\[z\]) of the semi logarithmic drug concentration-time curve, and is calculated as 0.693/lambda(z).

Relative Bioavailability (Frel) of JNJ-42165279Day 1 (Pre-dose and post-dose 0.25, 0.50, 1, 1.5, 2, 2.5, 3, 4, 6, 9, 12, 16, hours), Day 2 (24, 36 hours), Day 3, Day 4, Day 8 (Pre-dose and post-dose 0.25, 0.50, 1, 1.5, 2, 2.5, 3, 4, 6, 9, 12, 16, hours), Day 9 (24, 36 hours), Day 10, and Day 11

Relative bioavailability is the percentage of the administered dose that is systemically available.
