简要总结
The purpose of this study is to assess the effects of repeated once daily administration of 200 milligram (mg) of itraconazole (steady state) on the single-dose pharmacokinetics of JNJ 42847922 in healthy, male participants.
详细描述
This is an open-label (all people know the identity of the intervention), fixed-sequence, single-center, single-dose study designed to assess the effects of steady-state itraconazole exposure on the pharmacokinetics of a single oral dose of JNJ 42847922 in healthy male participants. The duration of study will be approximately of 6 weeks per participant. The study consists of 3 parts: Screening (that is, 21 days before study commences on Day 1); Open-label Treatment (6 days); and Follow-up (7 to 14 days after last dose of study drug or early withdrawal).
All eligible participants will receive single oral doses of 5 milligram (mg) JNJ-42847922 on Day 1 and Day 6. A daily dose of 200 mg itraconazole will be administered from Day 2 to Day 6. Followed by an overnight fast of at least 8 hours participants will be administered with study treatment 30 minutes after light breakfast. Participants will not be allowed to have food until 4 hours of drug administration. Blood samples will be collected for evaluation of pharmacokinetics at pre-dose and post-dose of study treatment. Participants' safety will be monitored throughout the study.

结局指标
主要结局
Maximum Plasma Concentration (Cmax) of JNJ-42847922
时间窗: up to Day 6
The Cmax is the maximum plasma concentration.
Time to Reach Maximum Concentration (tmax) of JNJ-42847922
时间窗: up to Day 6
The tmax is time to reach the maximum observed plasma concentration.
Time to Reach Last Quantifiable Plasma Concentration (tlast) of JNJ-42847922
时间窗: up to Day 6
The tmax is time to last observed quantifiable plasma concentration.
Area Under the Plasma Concentration-Time Curve From Time Zero to Last Quantifiable Time (AUC [0-last]) of JNJ-42847922
时间窗: up to Day 6
The AUC (0-last) is the area under the plasma concentration-time curve from time zero to last quantifiable time.
Area Under the Plasma Concentration-Time Curve From Time Zero to Infinite Time (AUC [0-infinity]) of JNJ-42847922
时间窗: up to Day 6
The AUC (0-infinity) is the area under the plasma concentration-time curve from time zero to infinite time, calculated as the sum of AUC(last) and C(last)/lambda(z), wherein AUC(last) is area under the plasma concentration-time curve from time zero to last quantifiable time; C(last) is the last observed quantifiable concentration; and lambda(z) is elimination rate constant.
Area Under the Plasma Concentration-Time Curve From Time Zero to 24 Hours (AUC [0-24]) of JNJ-42847922
时间窗: up to Day 6
The AUC (0-24) is the area under the plasma concentration-time curve from time 0 to time 24 hours
Apparent total body clearance (CL/F) of JNJ-42847922

Clearance is a quantitative measure of the rate at which a drug substance is removed from the body. The CL/F will be calculated by dividing the dose by AUC (0-infinity)
