A Single Ascending Dose Study to Investigate the Safety, Tolerability, and Pharmacokinetics of JNJ-42165279 in Healthy Male Participants

• Incidents of adverse events amongst participants (Part 1) [ Time Frame: Day -21 to Day 114 (~19 wks) ] [ Designated as safety issue: Yes ]
  As a measure of safety.
• Incidents of adverse events amongst participants (Part 2) [ Time Frame: Day -21 to Day 23 (~6 wks) ] [ Designated as safety issue: Yes ]
• Pharmacokinetics of JNJ-42165279 as measured by Cmax (Part 1) [ Time Frame: Day 1 to Day 4 ] [ Designated as safety issue: No ]
  Cmax is defined as maximum plasma concentration of JNJ-42165279.
• Pharmacokinetics of JNJ-42165279 as measured by Cmax (Part 2) [ Time Frame: Day 1 to Day 7 ] [ Designated as safety issue: No ]
• Pharmacokinetics of JNJ-42165279 as measured by AUC (Part 1) [ Time Frame: Day 1 to Day 4 ] [ Designated as safety issue: No ]
  AUC is defined area under the plasma concentration time curve from 0 to t hours post dosing of JNJ-42165279.
• Pharmacokinetics of JNJ-42165279 as measured by AUC (Part 2) [ Time Frame: Day 1 to Day 7 ] [ Designated as safety issue: No ]

• Fatty acid amide hydrolase (FAAH) inhibition in white blood cells (WBCs) (Part 1) [ Time Frame: Day 1 to Day 4 ] [ Designated as safety issue: No ]
• FAAH inhibition in WBC (Part 2) [ Time Frame: Day 1 to Day 7 and Day 9 ] [ Designated as safety issue: No ]
• Effects on mood (Part 1) [ Time Frame: Day 1 and Day 2 ] [ Designated as safety issue: No ]
  This is measured by scores on Patient Reported Outcome (PRO) questionnaires (Profile of Mood States [POMS], State version of the State-Trait Anxiety Inventory [STAIS], and the Exercise-Induced Feeling Inventory [EFI]). The POMS is a valid and reliable self-report scale that can be utilized to assess both positive and negative, transient, fluctuating mood states. The STAIS is a commonly-used, validated instrument to assess anxiety. The EFI assesses emotions commonly associated with exercise.
• Effects on mood (Part 2) [ Time Frame: Day 1 to Day 9 ] [ Designated as safety issue: No ]
• Effects on cognition (Part 1) [ Time Frame: Day -1 and Day 1 ] [ Designated as safety issue: No ]
  This is assessed by the time to complete Trail Making Test (TMT).
• Effects on cognition (Part 2) [ Time Frame: Day -1, Day 1 and Day 6 ] [ Designated as safety issue: No ]
• Effects on pain tolerance (Part 1) [ Time Frame: Day -1 to Day 2 ] [ Designated as safety issue: No ]
  This is measured by pressure pain tolerance threshold using an electronic pressure algometer.
• Effects on drowsiness (Part 2) [ Time Frame: Day 1 to Day 6 ] [ Designated as safety issue: No ]
  This is measured by Stanford Sleepiness Scale (SSS). This 7 point Likerttype scale is used to rate the drowsiness with the descriptors ranging from "feeling active, vital, alert, and wide awake" (score= 1) to "no longer fighting sleep, sleep onset soon, and having dream like thoughts" (score=7).

The purpose of this study is to investigate the safety, tolerability and pharmacokinetics of single ascending doses as well as repeated doses of JNJ-42165279 in healthy male participants.

This is a single-site, randomized (participants are assigned to treatment by chance), double-blind study (neither physician nor participant knows whether the participant is receiving active treatment or placebo). Placebo is an inactive substance that is compared with a drug to test whether the drug has a real effect. This study consists of two parts (part 1, single dosing and part 2, multiple dosing). Part 1: An alternating panel design will be used, whereby the first panel of 9 participants will receive the first, third, and fifth administered doses, while the second panel of 9 participants will receive the second, fourth, and sixth administered doses.Up to 2 additional dosings (1 per panel) may be evaluated to further understand the study drug. For each dose administration, 6 participants will be assigned to active treatment and 3 to placebo. Each participant will receive JNJ-42165279 on 2 occasions and placebo once during the first 3 dosings. The planned doses of JNJ-42165279 range from 2.5 to 500 mg. The sponsor and investigator will review blinded data associated with each dose prior to administration of the next dose. Participants will check into the study center the morning prior to each dosing (Day -1) and will remain at the center until discharge 72 hours after dosing (Day 4). Participants will be dosed approximately every 4 weeks. Part 2: A separate cohort of 9 healthy male volunteers will receive repeated daily dosing of 100 mg JNJ-42165279 or placebo (6 participants will receive JNJ-42165279 and 3 participants will receive placebo) for 6 consecutive days. Participants will check into the study center the morning prior to their first dosing (Day -1) and will remain at the center until discharge 72 hours after receiving their last dose on Day 6. Participants in Part 1 and 2 will return for a follow-up visit 7 to 14 days after their final discharge from the study center.
