A Study of JNJ-64264681 and JNJ-67856633 in Participants With Non-Hodgkin Lymphoma and Chronic Lymphocytic Leukemia

August 20, 2025 updated by: Janssen Research & Development, LLC

A Phase 1b, Open-Label Study of the Safety, Pharmacokinetics, and Pharmacodynamics of JNJ-64264681 in Combination With JNJ-67856633 in Participants With Non-Hodgkin Lymphoma and Chronic Lymphocytic Leukemia

The primary purpose of this study is to determine: the recommended Phase 2 doses (RP2Ds) of JNJ-64264681 and JNJ 67856633 when administered together in participants with B cell non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukemia (CLL) (Part A - Dose Escalation); and the safety of the RP2Ds for this combination in different histologies/participant populations (Part B - Cohort Expansion).

Detailed Description

Bruton's tyrosine kinase (BTK) is a cytoplasmic tyrosine kinase that plays a critical role in B cell activation via the B cell receptor (BCR) signaling pathway. BTK is important for normal B-cell activation and the pathophysiology of B cell malignancies. A few BTK inhibitors have demonstrated clinical activity in non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukemia (CLL). Non-Hodgkin lymphoma represents a diverse set of diseases, of which more than 60 subtypes have been identified and classified by the world health organization. JNJ-64264681 is a second-generation, orally active, selective, and irreversible covalent inhibitor of BTK and JNJ-67856633 is an orally bioavailable, potent, and selective first in class mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1) inhibitor that binds to an allosteric site on MALT1 with a mixed-type mechanism. JNJ-64264681 and JNJ-67856633 inhibit BTK and MALT1, respectively, and both BTK and MALT1 are involved in transmitting the pro-survival BCR signal. The study will consist of Screening Phase (28 days); Treatment Phase (from Cycle 1 Day 1 up to end of treatment, each cycle is a 21-day cycle) and a Follow-up Phase (from end of treatment visit until lost to follow-up, withdrawal of consent, death, 6 months after start of first subsequent antineoplastic therapy, after the clinical cut off (CCO) date participants will be withdrawn from the study 30 days after the last dose of study drugs were administered). The total study duration is estimated at 2 years and 2 months. Safety assessments will include physical examinations, vital signs, electrocardiograms, clinical safety laboratory assessments, eastern cooperative oncology group performance status, echocardiogram, and adverse events monitoring.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Part A: Number of Participants with Dose-limiting Toxicity (DLT)
Time Frame: 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.
Up to 28 days
Part A and Part B: Number of Participants with Adverse Events (AEs) as a Measure of Safety and Tolerability
Time Frame: Up to 3 years and 9 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.
Up to 3 years and 9 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
