Brief summary
The purpose of this study is to evaluate the safety of JNJ-42847922 following single oral administration.
Detailed description
This is a single center, double-blind (neither the researchers nor the participants know what treatment the participant is receiving), placebo-controlled (an inactive substance; a pretend treatment \[with no drug in it\] that is compared in a clinical trial with a drug to test if the drug has a real effect), randomized (study medication assigned to participants by chance), single-ascending dose study. The study consists of a screening phase, an in-clinic treatment phase, and a follow-up phase. The study duration for each subject will be approximately 5 weeks from screening (Day -28 to Day -3), in-clinic period (Day -2 to Day 4) to follow up visit (Day 8). Participants will receive a single oral dose of JNJ-42847922 or placebo in 3 cohorts. Participants' safety will be monitored throughout the study.
Interventions
Participants will receive single oral dose of 5 milligram (mg) of JNJ-42847922 on Day 1, fasted condition.
Participants will receive single oral dose of 20 mg of JNJ-42847922 on Day 1, fasted condition.
DRUGJNJ-42847922, 40 mg
Participants will receive single oral dose of 40 mg of JNJ-42847922 on Day 1, fasted condition.
DRUGPlacebo
Participants will receive placebo on Day 1, fasted condition in Cohort A, Cohort B and Cohort C.
