Study Endpoints

Primary Endpoints

Number of Participants with Serious Adverse Events (SAEs) and Grade Greater than or equals to (>=) 3 Related Adverse Events (AEs)
Up to approximately 3 years and 7 months

An AE is any untoward medical occurrence in a clinical study participant administered a pharmaceutical (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the treatment. An SAE is any untoward medical occurrence that results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect in the offspring of a study participant, is considered or defined as an important medical event, or abnormal pregnancy outcomes.

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

Long Term Safety Assessment (Platform Study)OTHERThe platform rollover study provides continued long-term access to study treatment(s) (JNJ-64264681; JNJ-67856633 (safimaltib); JNJ-54179060 (ibrutinib); JNJ-75348780; JNJ-74856665; JNJ-64619178; JNJ-70218902; JNJ-80948543; JNJ-87801493) for participants currently receiving the active study treatment in parent studies and deriving benefit from it. Eligible participants in parent study will rollover to this platform study which will be adapted into Intervention Specific Appendix (ISA) within the platform study. Participants will initiate the platform study under the relevant ISA, and will continue to receive study treatment at the dose they received in parent study.
Part A: Dose EscalationEXPERIMENTALParticipants will receive JNJ-75348780. The dose levels will be escalated sequentially based on the decisions of the Study Evaluation Team (SET), along with the potential exploration of other routes of administration and schedules, until one or more recommended Phase 2 Doses (RP2D) have been identified.
Part B: Cohort ExpansionEXPERIMENTALParticipants will receive JNJ-75348780 at one of the putative RP2Ds determined in Part A.
