Eligibility Criteria
-----------------
Inclusion Criteria: A body mass index (BMI) between 18 and 32 kilogram per square meter (kg/m^2), inclusive (BMI = weight/height^2) Healthy on the basis of physical examination, medical history, vital signs, and 12-lead electrocardiogram (ECG) [inclusive QTcF less than or equal to (<=) 450 millisecond (msec) for males and <= 470 msec for females] performed at screening and admission (Treatment period 1) to the clinical unit. Minor abnormalities in ECG, which are not considered to be of clinical significance by the physician investigator, are acceptable. The presence of Left Bundle Branch Block (LBBB), atrioventricular (AV) Block (second degree or higher), or a permanent pacemaker or implantable cardioverter defibrillator [ICD] will lead to exclusion Healthy on the basis of clinical laboratory tests performed at Screening. If the results of the serum chemistry panel [excluding liver function tests], hematology [including coagulation], or urinalysis are outside the normal reference ranges, the participant may be included only if the investigator judges the abnormalities to be not clinically significant. This determination must be recorded in the participant's source documents and initialed/signed by the physician investigator Must be willing to adhere to the prohibitions and restrictions specified in this protocol Must sign an informed consent form (ICF) indicating that he or she understands the purpose of and procedures required for the study and are willing to participate in the study Exclusion Criteria: History of or current liver or renal insufficiency (estimated creatinine clearance below 60 milliliter per minute [mL/min]); significant cardiac, vascular, pulmonary, gastrointestinal, endocrine, neurologic, hematologic (including coagulation disorders), rheumatologic, psychiatric, or metabolic disturbances, any inflammatory illness or any other illness that the Investigator considers should exclude the participant History of hepatitis B surface antigen (HBsAg) or hepatitis C antibody (anti-HCV) positive, or other clinically active liver disease, or tests positive for HBsAg or anti-HCV at Screening History of human immunodeficiency virus (HIV) antibody positive, or tests positive for HIV at Screening History of malignancy within 5 years before screening (exceptions are squamous and basal cell carcinomas of the skin and carcinoma in situ of the cervix, or malignancy that, in the opinion of the investigator, with written concurrence with the sponsor's medical monitor, is considered cured with minimal risk of recurrence) History of at least mild drug or alcohol use disorder according to Diagnostic and Statistical Manual of Mental Disorders (latest edition DSM-5) criteria within 6 months before Screening

What is the study measuring?

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Maximum Plasma Concentration (Cmax) of JNJ-54175446 | The Cmax is the maximum observed plasma concentration. | Predose, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96, 120, 144 hour post dose | 
| Time to Reach Maximum Plasma Concentration (Tmax) of JNJ-54175446 | The Tmax is defined as actual sampling time to reach maximum plasma concentration. | Predose, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96, 120, 144 hour post dose | 
| Area Under the Plasma Concentration-Time Curve From Time Zero to Time 't' (AUC[0-t]) of JNJ-54175446 | The AUC(0-t) is the area under the plasma concentration-time curve from time zero to any time 't'. | Predose, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96, 120, 144 hour post dose | 
| Area Under the Plasma Concentration-Time Curve From Time Zero to Infinite Time (AUC[0-infinity]) of JNJ-54175446 | The AUC (0-infinity) is the area under the plasma concentration-time curve from time zero to infinite time, calculated as the sum of AUC(0-last) and C(last)/lambda(z); wherein AUC(0-last) is area under the plasma concentration-time curve from time zero to last quantifiable time, C(last) is the last observed quantifiable concentration, and lambda(z) is elimination rate constant. | Predose, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96, 120, 144 hour post dose | 
| Elimination Rate Constant (Lambda[z]) of JNJ-54175446 | Lambda(z) is first-order elimination rate constant associated with the terminal portion of the curve, determined as the negative slope of the terminal log-linear phase of the drug concentration-time curve. | Predose, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96, 120, 144 hour post dose | 
| Elimination Half-Life (t1/2) of JNJ-54175446 | The elimination half-life (t1/2) is the time measured for the plasma concentration to decrease by 1 half to its original concentration. It is associated with the terminal slope of the semi logarithmic drug concentration-time curve, and is calculated as 0.693/lambda(z). | Predose, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96, 120, 144 hour post dose |
