Study Groups

Part 1 (Panel 1): JNJ-55375515 and placebo

Participants will receive dose level (DL) 1 of JNJ-55375515 (starting dose) or placebo on Day 1 of period 1 based on their randomization sequence 1, 2 or 3. Dose of the study medication will be escalated to DL 3 (period 2) and a maximum of DL 5 (period 3) based on the safety and tolerability profile and pharmacodynamic (PD) profile assessed at the preceding dose level. A wash-out period of at least 10 days will be maintained between study drug administrations.

Group Type: EXPERIMENTAL

JNJ-55375515 Dose Level 1

Intervention Type: DRUG

Participants will receive JNJ-55375515 orally at a Dose level 1 in Part 1 of study.

Intervention Type: DRUG

Participants will receive JNJ-55375515 orally at a Dose level 3 in Part 1 of study.

JNJ-55375515 Dose Level 5

Intervention Type: DRUG

Participants will receive JNJ-55375515 orally at a Dose level 5 in Part 1 of study.

Placebo

Intervention Type: DRUG

All participants will receive matching placebo orally in Part 1 and Part 2 of the study.

Part 1 (Panel 2): JNJ-55375515 and placebo

Participants will receive DL 2 of JNJ-55375515 (starting dose) or placebo on Day 1 of period 1 based on their randomization sequence 1, 2 or 3. Dose of the study medication will be escalated to DL 4 (period 2) and a maximum of DL 6 (period 3) based on the safety and tolerability profile and PD profile assessed at the preceding dose level. A wash-out period of at least 10 days will be maintained between study drug administrations.

Group Type: EXPERIMENTAL

JNJ-55375515 Dose Level 2

Intervention Type: DRUG

Participants will receive JNJ-55375515 orally at a Dose level 2 in Part 1 of study.

JNJ-55375515 Dose Level 4

Intervention Type: DRUG

Participants will receive JNJ-55375515 orally at a Dose level 4 in Part 1 of study.

JNJ-55375515 Dose Level 6

Intervention Type: DRUG

Participants will receive JNJ-55375515 orally at a Dose level 6 in Part 1 of study.

Placebo

Intervention Type: DRUG

All participants will receive matching placebo orally in Part 1 and Part 2 of the study.

Part 2: JNJ-55375515 and placebo

Participants will randomly be assigned to one of four treatment sequences 1, 2, 3 or 4. In the first 3 sequences, participants will receive 2 doses of JNJ-55375515 and placebo. Participants assigned to sequence 4 will receive placebo only in all periods. 3 dose levels will be tested in Part 2 based on Part 1 and will not exceed those evaluated in Part 1. A wash-out period of at least 10 days will be maintained between study drug administrations in period 1, 2, 3 and 4. In period 4 (open-label pharmacokinetic (PK) assessment period) participants will be randomly assigned to one of two dose levels tested in periods 1 to 3.

Eligibility Criteria

Inclusion Criteria

• Body Mass Index (BMI) between 18 and 30 kilogram / square meter (kg/m^2) inclusive (BMI=weight/height^2)
• Participant must be healthy based on clinical laboratory tests performed at screening. If the results of the serum chemistry panel, hematology, coagulation or urinalysis are outside the normal reference ranges, retesting of an abnormal lab value (s) that may lead to exclusion will be allowed once during the screening phase. It is expected that laboratory values will generally be within the normal range for the laboratory, though minor deviations, which are not considered to be of clinical significance to the investigator, are acceptable
• Participant must be healthy based on physical and neurological examination, medical history, vital signs, and 12-lead Electrocardiography (ECG) [including QTcF less than or equal to (<=) 450 millisecond (msec)] performed at screening, admission to the clinical unit and pre dose on Day 1 of Period 1. Abnormalities, which are not considered to be of clinical significance by the investigator, are acceptable. The presence of Left Bundle Branch Block (LBBB), AV Block (second degree or higher), or a permanent pacemaker or implantable cardioverter defibrillator [ICD] will lead to exclusion
• Non-smoker (not smoked for 3 months prior to screening)
• During the study and for a minimum of 1 spermatogenesis cycle (defined as approximately 90 days) after receiving the last dose of study drug, in addition to the highly effective method of contraception, a man who is sexually active with a woman of childbearing potential must agree to use a barrier method of contraception (for example, condom with spermicidal foam/gel/film/cream/suppository); who is sexually active with a woman who is pregnant must use a condom; must agree not to donate sperm

Exclusion Criteria

• History of or current significant medical illness including (but not limited to psychotic, bipolar, major depressive, or anxiety disorder)
• Cardiac arrhythmias or other cardiac disease, hematological disease, lipid abnormalities, respiratory disease, diabetes mellitus, renal or hepatic insufficiency, thyroid disease, Parkinson's disease, infection, or any other illness that the Investigator considers should exclude the participant
• Serology positive for hepatitis B surface antigen (HBsAg), hepatitis C virus (HCV) antibodies or human immunodeficiency virus (HIV) antibodies
• Participant has a history of or current vestibular disease including (but not limited to) Meniere's disease, benign paroxysmal positional vertigo (BPPV), vestibular neuronitis, vestibular schwannoma or vestibular migraine
• Only for part 2: Has a current diagnosis or history of narcolepsy, central sleep apnea, sleep related hypoventilation, circadian rhythm sleep-wake disorders, substance/medication induced sleep disorder or parasomnias (non-rapid eye movement sleep arousal disorders, nightmare disorder, rapid eye movement sleep behavior disorder); obstructive sleep apnea/hypopnea (apnea/hypopnea index greater than (>)10) or restless legs syndrome (periodic leg movements with arousal index >15); night-shift worker or significantly shifted diurnal activity pattern (it is expected that eligible participant normally wake up between 6:00 am - 8:00 am and go to bed between 10:00 pm - 12:00 am); usual bedtime outside of 10:00 pm and 12:00 am and taking, on average, less than 6 hours or more than 9 hours of bed rest
