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

A Study to Investigate the Effect of Increased Gastric pH From the Administration of the Proton Pump Inhibitor (PPI) Rabeprazole on the Oral Bioavailability of the Orexin-2 Receptor Antagonist JNJ-42847922 in Healthy Subjects

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.

Study Overview

• Status: Completed
• Conditions: Healthy
• Intervention / Treatment: Drug: JNJ-42847922; Drug: Rabeprazole

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.

• Clinically significant abnormal values for hematology, clinical chemistry, urinalysis, or thyroid stimulating hormone (TSH) at screening or at admission to the study center (Day -1) as deemed appropriate by the investigator
• Clinically significant abnormal physical examination, vital signs, or 12-lead electrocardiogram (ECG) at screening or at admission to the study center (Day -1) as deemed appropriate by the investigator
• Use of any prescription or nonprescription medication, within 7 days before the first scheduled dose of the study drug (including vitamins and herbal supplements), except acetaminophen and hormonal replacement therapy

What is the study measuring?

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.

Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)	An AE was 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. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged in-patient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.	7 to 14 days after last dose of study drug or early withdrawal)
