Investigators
Eligibility Criteria
Inclusion Criteria
- •Body mass index (BMI; weight \[kilogram {kg}\]/height \[meter square {m\^2}\]) between 18 and 35 kilogram per meter square (kg/m\^2), inclusive, and a body weight greater than 50 kg but less than 110 kg at screening and Day -
- •For participants to be enrolled in the highest dose cohort (Cohort 3), additional weight limitations will apply in order not to exceed the total dose of 5 gram (g) JNJ-63733657; the participant weight in the highest dose cohort will be limited
- •Women must not be of childbearing potential
Exclusion Criteria
- •History of or current clinically significant medical illness including (but not limited to) cardiac arrhythmias or other cardiac disease, hematologic disease, coagulation disorders (including any abnormal bleeding or blood dyscrasias), lipid abnormalities, significant pulmonary disease, including bronchospastic respiratory disease, diabetes mellitus, hepatic or renal insufficiency, thyroid disease, neurologic or psychiatric disease, infection, or any other illness that the investigator considers should exclude the participant or that could interfere with the interpretation of the study results
- •Clinically significant abnormal values for hematology, clinical chemistry, coagulation, or urinalysis at screening and Day -1 in the opinion of the investigator
- •Clinically significant abnormal physical or neurologic examination (including fundoscopy), vital signs, or 12-lead electrocardiogram (ECG) at screening and Day -1 in the opinion of the investigator
- •Positive result on hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb), hepatitis C virus (HCV) antibody (antiHCV) positive, or any other clinically active liver disease at screening (per screening evaluations)
- •History of human immunodeficiency virus (HIV) antibody positive, tests positive for HIV or tests positive for syphilis at screening
- •Mini-Mental State Examination (MMSE) score less than or equal to (\<=) 27 at screening

Outcomes
Primary Outcomes
Number of Participants with Adverse Events (AEs) as a Measure of Safety and Tolerability
Time Frame: Approximately 23 weeks
An AE is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product.
