| Phase 1 |
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.

Outcome Measures
Primary Outcome Measures
- Maximum Observed Plasma Concentration (Cmax) of JNJ-42165279 [Day 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-42165279 [Day 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-42165279 [Day 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-42165279 [Day 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-42165279 [Day 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-42165279 [Day 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-42165279 [Day 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.
