A Study to Investigate the Effect of Increased Gastric pH on the Oral Bioavailability of the Orexin-2 Receptor Antagonist JNJ-42847922 in Healthy Participants

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to assess the effects of daily administration of rabeprazole on the single-dose pharmacokinetics of JNJ-42847922 in healthy participants.

Detailed Description
-----------------
This is an open-label, single-center, fixed-sequence study designed to assess the effects of multiple oral administration of rabeprazole (a PPI) on the pharmacokinetics of a single oral dose of JNJ-42847922 in healthy participants. The study consists of 3 phases: a Screening Phase of approximately 4 weeks (Days -29 to -2); an Open Label Treatment Phase (Days -1 to 7); and an End-of-Study Phase occurring from 7 to 14 days after the last dose of study drug. All participants will receive JNJ-42847922, orally on Day 1 (alone) and Day 6 (along with rabeprazole).Rabeprazole will be administered orally on Day 2 to Day 6. Pharmacokinetics will primarily be for JNJ-42847922, M12 metabolite and M16 metabolite. Participant's safety will be monitored throughout the study.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Area Under the Plasma Concentration-Time Curve From Time 0 to Time of the Last Quantifiable Concentration (AUC [0-last]) of JNJ-42847922 | Area under the plasma concentration-time curve from time 0 to the last quantifiable concentration of JNJ-42847922 will be reported. | Pre-dose; 10, 20, 30, 45 minutes; 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 16, 24 hours after study drug administration on Day 1 and Day 6 | 
| Area Under the Plasma Concentration-Time Curve From Time Zero to Infinite Time (AUC[0-infinity]) of JNJ-42847922 | 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. | Pre-dose; 10, 20, 30, 45 minutes; 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 16, 24 hours after study drug administration on Day 1 and Day 6 |
