Study Endpoints
Primary Endpoints
Part 1: Number of Participants with Dose Limiting Toxicity (DLTs)
Up to first 21 days after first dose

The DLTs are adverse events including certain high grade non-hematologic or hematologic toxicities, or toxicities meeting other specific criteria.

Part 1 and Part 2: Number of Participants with Adverse Events (AEs) by Severity
Up to 3 years

An AE is any untoward medical occurrence in a clinical study participant administered an investigational or non-investigational product and it does not necessarily have a causal relationship with the investigational product. Severity will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0 with the exception of cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome events (ICANS), which will be graded by American Society for Transplantation and Cellular Therapy (ASTCT) guidelines. 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.

Secondary Endpoints
Part 1 and Part 2: Serum Concentration of JNJ-79032421
Up to 3 years
Part 1 and Part 2: Maximum Observed Analyte Concentration (Cmax) of JNJ-79032421
Up to 3 years
Part 1 and Part 2: Time to Reach Maximum Observed Analyte Concentration (Tmax) of JNJ-79032421
