A Study to Assess the Effects of Itraconazole and Rifampicin on the Single-Dose Pharmacokinetics of JNJ-53718678 in Healthy Adults

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to assess the effects of itraconazole, a strong cytochrome P (CYP)3A4 and p-glycoprotein (PgP) inhibitor, and rifampicin, a CYP3A4, uridine 5'-diphospho-glucuronosyltransferase (UGT), and PgP inducer, and an inhibitor of organic anion-transporting polypeptide (OATP), on the single-dose pharmacokinetics (PK) of JNJ-53718678 in healthy adult participants.

Detailed Description
-----------------
This is a single-center, open-label, fixed sequence, Phase 1 study in healthy adult participants to study the effects of itraconazole and rifampicin on the pharmacokinetics, safety, and tolerability of a single dose of JNJ-53718678. This study will be conducted in 2 separate panels, with 14 participants in Panel 1 and 16 participants in Panel 2. The study consists of following phases: Screening (28 days), Treatment phase (11 days) and Follow-up (10 to 14 days after the last study drug intake). Blood samples will be collected for evaluation of pharmacokinetics at pre-dose and post-dose of study treatment. Participants will be assessed for safety and tolerability throughout the study.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Maximum Observed Analyte Concentration (Cmax) | The Cmax is the maximum observed analyte concentration after the JNJ-53718678 doses on Day 1, Day 4 (Panel 2 only) and Day 9. | Up to 11 days | 
| Area Under the Analyte Concentration-Time Curve From Time 0 to the Time of the Last Measurable Concentration (AUC [0-last]) | The (AUC [0-last]) is the area under the analyte concentration-time curve from time 0 to time of the last quantifiable concentration after the JNJ-53718678 doses on Day 1 and Day 9. | Up to 11 days | 
| Area Under the Analyte Concentration-Time Curve From Time 0 to Infinite Time (AUC [0-infinity]) | The AUC (0-infinity) is the area under the Analyte concentration-time curve from time 0 to infinite time after the JNJ-53718678 doses on Day 1 and Day 9, calculated as the sum of AUC(0-last) and C(0-last)/lambda(z), wherein AUC(0-last) is the area under the analyte concentration-time curve from time 0 to time of the last quantifiable concentrations; C(0-last) is the last observed quantifiable concentration; and lambda(z) is elimination rate constant. | Up to 11 days | 
| Area Under the Analyte Concentration-time curve From Time 0 to 24h (AUC24h) | The AUC24h is the area under the analyte concentration-time curve from time 0 to 24h after dosing on Day 1 and Day 4 (Panel 2 only). | Up to 11 days | 
| Ratio of Individual Cmax Values Between Test and Reference Treatment (Ratio Cmax, test/reference) | Ratio Cmax, test/reference is the ratio of individual Cmax values between test (JNJ-53718678 with itraconazole, on Day 9, or JNJ-53718678 with rifampicin, on Day 4 and Day 9) and reference (without itraconazole or rifampicin, on Day 1) treatments. | Up to 11 days | 
| Ratio of Individual AUC24h Values Between Test and Reference Treatment (Ratio AUC24h, test/reference) | Ratio AUC24h, test/reference is the ratio of individual AUC24h values between test (JNJ-53718678 with rifampicin, on Day 4) and reference (without rifampicin, on Day 1) treatments. | Up to 11 days | 
| Ratio of Individual AUClast Values Between Test and Reference Treatment (Ratio AUClast, test/reference) | Ratio AUClast, test/reference is the ratio of individual AUClast values between test (JNJ-53718678 with itraconazole or rifampicin, on Day 9) and reference (without itraconazole or rifampicin, on Day 1) treatments. | Up to 11 days | 
| Ratio of Individual AUC(infinity) Values Between Test and Reference Treatment (Ratio AUC[infinity], test/reference) | Ratio AUC(infinity), test/reference is the ratio of individual AUC(infinity) values between test (JNJ-53718678 with itraconazole or rifampicin, on Day 9) and reference (without itraconazole or rifampicin, on Day 1) treatments. | Up to 11 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With Adverse Events and Serious Adverse Events | An adverse event is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product. | Screening up to Follow-up (30 to 35 days after last study drug intake) |
