Summary

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after start of first subsequent antineoplastic therapy, after the clinical cut off (CCO) date participants will be withdrawn from the study 30 days after the last dose of study drugs were administered).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.
