Study Endpoints

Primary Endpoints

Serum Concentrations of JNJ-63733657
Up to Week 13

Serum samples will be analyzed to determine concentrations of JNJ-63733657 using a validated, specific, and sensitive Immunoassay method.

Number of Participants with Adverse Events (AEs) as a Measure of Safety and Tolerability
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.

Single Ascending Dose (SAD) (Part 1): Number of Subjects With Adverse Events as a Measure of Safety and Tolerability of JNJ-63733657
Up to Day 106

An adverse event is any untoward medical event that occurs in a subject administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product.

Multiple Ascending Dose (MAD) (Part 2): Number of Subjects With Adverse Events as a Measure of Safety and Tolerability of JNJ-63733657
Up to Day 162

An adverse event is any untoward medical event that occurs in a subject administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product.

Secondary Endpoints

Percentage of Participants with Treatment-emergent Adverse Events (TEAEs) by Severity
Up to Week 13
Percentage of Participants with Discontinuations due to AEs
Up to Week 17
Percentage of Participants with Serious Adverse Events (SAEs)

ArmTypeDescription
JNJ-63733657EXPERIMENTALParticipants will receive a single dose of JNJ-63733657 as an intravenous (IV) infusion on Day 1.
Cohort 1: JNJ-63733657 or PlaceboEXPERIMENTALParticipants will receive a single intravenous (IV) low dose of JNJ-63733657 or matching placebo.
Cohort 2: JNJ-63733657 or PlaceboEXPERIMENTALParticipants will receive a single IV middle dose of JNJ-63733657 or matching placebo.
Cohort 3: JNJ-63733657 or PlaceboEXPERIMENTALParticipants will receive a single IV high dose of JNJ-63733657 or matching placebo.
SAD (Part 1): Healthy SubjectsEXPERIMENTALIn Part 1, single ascending intravenous (IV) doses of JNJ-63733657 or placebo will be administered to sequential cohorts (Cohorts 1 to 5) of healthy subjects on Day 1. The progression to the next (higher) dose level is dependent on acceptable safety and tolerability profile of JNJ-63733657 obtained after dose administration of the current dose level. Here, SAD indicates single ascending dose.
MAD (Part 2): Subjects With Alzheimer's Disease (AD)EXPERIMENTALIn Part 2, multiple ascending IV doses of JNJ-63733657 or placebo will be evaluated at three dose levels in sequential cohorts in subjects with prodromal or mild AD; 3 doses will be administered over a period of 8 weeks (Day 1, Day 29, Day 57). The starting dose will be decided based on the data from Part 1. Escalations will be done based on safety and tolerability similar to Part 1. Doses will not exceed those tested in Part 1. Here, MAD indicates multiple ascending dose.
