The purpose of this study is to assess the effects of strong cytochrome P450 (CYP) 3A4 inhibitors (Itraconazole and Clarithromycin), on pharmacokinetics (PK) (study of the way a drug enters and leaves the blood and tissues over time) of single dose of JNJ-54861911 in healthy male participants.
This is a single-center, open-label (participants and researchers are aware about the treatment, participants are receiving), fixed-sequence study in healthy male participants consisting of 2 sequential parts. For all participants enrolled in either part, the study consists of 3 phases: Screening Phase (within 21 to 2 days prior to the first dose administration on Day 1), Open-label Treatment Phase (Day 1 up to Day 12), and Follow-up Phase (7 to 14 days after last dose administration). The maximum duration of study will be 7 weeks per participant. Study will be conducted in 2 parts to understand the relative role of CYP3A4 and amide hydrolysis pathways in JNJ-54861911 metabolism and any potential drug-drug interaction liability with inhibitors of these pathways. Itraconazole will be administered in Part 1 as mixed CYP3A4 and potential amide hydrolysis inhibitor. Clarithromycin will be administered in Part 2 as a pure CYP3A4 inhibitor. However, Part 2 of the study will only be conducted if a relevant interaction is observed with itraconazole based on an interim review of Part 1 data. Participants enrolled in Part 1 will receive single dose of JNJ-54861911, 25 milligram (mg) tablet orally on Day 1 and Day 9 along with itraconazole 200 mg (2\*100 mg capsule) orally once daily from Day 5 to Day 12. Participants enrolled in Part 2 will receive single dose of JNJ-54861911, 25 mg tablet orally on Day 1 and Day 9 along with clarithromycin 500 mg immediate release tablet orally twice daily from Day 5 to Day 12. Blood samples will be collected pre-dose (Day 1) up to Day 13 to understand the PK characteristics of JNJ-54861911 and diaminothiazine (DIAT, a metabolite formed after amide hydrolysis of JNJ-54861911). In addition, a blood sample will be collected on Day -1 from all enrolled participants to study genotyping of CYP3A4 gene and other genetic factors that may influence the PK, safety, and/or tolerability of JNJ-54861911 and CYP3A4 inhibitors. Participants' safety will be monitored throughout the study.

Maximum Observed Plasma Concentration (Cmax) of JNJ-54861911 and diaminothiazine (DIAT)
The Cmax is the maximum observed plasma concentration.
Time frame: Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 16, 18, 24, 36, 48, 72, 96 hours post-dose on Day 1 and 9
Time to Reach Maximum Concentration (Tmax) of JNJ-54861911 and DIAT
The Tmax is time to reach the maximum observed plasma concentration.
Time frame: Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 16, 18, 24, 36, 48, 72, 96 hours post-dose on Day 1 and 9
Time to Last Quantifiable Plasma Concentration (Tlast) of JNJ-54861911 and DIAT
The Tlast is time to last observed quantifiable plasma concentration (Clast).
Time frame: Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 16, 18, 24, 36, 48, 72, 96 hours post-dose on Day 1 and 9
Area Under the Plasma Concentration-time Curve From Time Zero to Last Quantifiable Time (AUC [0-last]) of JNJ-54861911 and DIAT
The AUC (0-last) is area under the plasma concentration-time curve from time zero to time of last quantifiable concentration.
Time frame: Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 16, 18, 24, 36, 48, 72, 96 hours post-dose on Day 1 and 9
Area Under the Plasma Concentration-time Curve From Time Zero to Extrapolated Infinite Time (AUC [0-infinity]) of JNJ-54861911 and DIAT
The AUC (0-infinity) is the area under the plasma concentration-time curve from time zero to extrapolated infinite time, calculated as the sum of AUC (0-last) and Clast/lambda(z), where AUC (0-last) is area under the plasma concentration-time curve from time zero to last quantifiable time; Clast is the last observed quantifiable concentration; and lambda(z) is first-order rate constant associated with the terminal portion of the semilogarithmic drug concentration-time curve.
Time frame: Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 16, 18, 24, 36, 48, 72, 96 hours post-dose on Day 1 and 9
