Study Endpoints
Primary Endpoints
Part A and Part B: Number of Participants with Adverse Events (AEs) as a Measure of Safety and Tolerability
Up to 2 years 10 months

An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study.

Part A and Part B: Number of Participants with AEs by Severity
Up to 2 years 10 months

Severity will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0. Severity scale ranges from Grade 1 (Mild) to Grade 5 (Death). Grade 1= Mild, Grade 2= Moderate, Grade 3= Severe, Grade 4= Life-threatening, and Grade 5= Death related to adverse event.

Part A and Part B: Number of Participants with Dose-Limiting Toxicity (DLT)
Up to 28 days

Number of participants with DLT will be assessed. The DLTs are specific adverse events and are defined as any of the following: high grade non-hematologic toxicity, or hematologic toxicity.

Secondary Endpoints
Area Under the Concentration-time Curve From Time Zero to End of Dosing Interval (AUCtau) of JNJ-75348780
Up to 2 years 10 months
Maximum Observed Serum Concentration (Cmax) of JNJ-75348780
Predose, 48 hours postdose (up to 2 years 10 months)
Minimum Observed Serum Concentration (Cmin) of JNJ-75348780
