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.

Interventions

JNJ-42847922 will be administered as 20 mg tablet orally.

DRUGRabeprazole

Rabeprazole will be administered as 20 mg tablet orally.

Inclusion criteria

* If a woman, must be postmenopausal (no spontaneous menses for at least 2 years) or surgically sterile (including but not limited to hysterectomy, oophorectomy, salpingectomy, tubal ligation, and tubal occlusion). Women must agree to not donate eggs (ova, oocytes) during the study and for 3 months after the last dose of study drug. Women of child-bearing potential or currently breastfeeding a child are not allowed to participate in the study * If a man, must agree to use an adequate contraception method as deemed appropriate by the investigator (e.g., vasectomy, double-barrier, partner using effective contraception) and to not donate sperm during the study and for 3 months after receiving the last dose of study drug * Body mass index (BMI) (weight \[kilogram {kg}/height\^2 \[meter\]\^2) between 18 and 30 kg/m\^2 (inclusive), and body weight not less than 50 kg * Blood pressure (after the participant is supine for 5 minutes) between 90 and 140 millimeter of mercury (mmHg) systolic, inclusive, and no higher than 90 mmHg diastolic * A participants must be a non-smoker

Exclusion criteria

* Current or history of gastrointestinal disorder * Clinically significant medical illness including (but not limited to) cardiac arrhythmias or other cardiac disease, hematologic disease, coagulation disorders (including any abnormal bleeding or blood dyscrasias), lipid abnormalities, significant pulmonary disease, including bronchospastic respiratory disease, diabetes mellitus, renal or hepatic insufficiency, thyroid disease, neurologic disease, infection, hypertension or vascular disorders, kidney or urinary tract disturbances, significant psychiatric disorder (history of or current diagnosis), history of epilepsy or fits of unexplained black-outs, or any other illness that the investigator considers should exclude the participant or that could interfere with the interpretation of the study results * 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
