Pilot Study to Evaluate the Duration of Effects on Simulated Car Driving and Cognitive Performance After a Single Dose of JNJ-42847922, Zolpidem and Placebo in Healthy Participants

This is a single center, double-blind (neither Investigator nor participant knows which treatment the participant receives), randomized (study drug assigned by chance), 3-way cross-over (the same medications provided to all participants but in different sequence), pilot study in healthy male and female participants. Participants will be randomly assigned to 1 of 6 treatment and planning sequences. The study will consist of 3 parts: Screening Phase (between 21 days and 1 day prior to the first dose administration), a 3-way crossover double-blind, single dose treatment Phase and follow-up Phase (7 to 10 days after last dose administration). The maximum study duration for each participant will not exceed 7 weeks. The double-blind crossover treatment phase will consist of 3 treatment periods separated by a washout period of at least 3 days between dosing. Participants will receive either Treatment A (2 capsules of 20 milligram [mg] JNJ-42847922), Treatment B (10 mg zolpidem and 1 placebo capsule) or Treatment C (2 placebo capsules) in each treatment period. Driving performance will be assessed primarily by the mean difference of standard deviation of lateral position (SDLP) from an on road driving test. Participants' safety will be monitored throughout the study.

Inclusion criteria

• Body mass index (BMI) (weight [kg]/height^2[m^2]) between 18 and 30 kg/m^2 (inclusive)
• Men who are sexually active with a woman of childbearing potential must agree to use a condom, and all men must not donate sperm during the study and for 3 months after receiving the last dose of study drug. In addition, for men who have not had a vasectomy, their female partners should also use an appropriate method of birth control for at least the same duration
• A woman of childbearing potential must have a negative serum pregnancy test at screening and a negative urine pregnancy test pre-dose on Day 1 of each period
• A woman must agree not to donate eggs (ova, oocytes) for the purposes of assisted reproduction during the study and for at least 3 months after receiving the last dose of study drug
• Participant has a valid driving license for more than 3 years, has driven at least 5000 kilometer (km) in the past year and is driving a car regularly
• Women of childbearing potential must practice a highly effective method of birth control consistent with local regulations regarding the use of birth control methods for participants participating in clinical studies (that is, one that results in a less than 1 percent per year failure rate when used consistently and correctly)

A significant primary sleep disorder is exclusionary
