Non-Hodgkin lymphoma (NHL) represents the most frequent hematologic malignancy in the world and represents a diverse set of diseases. JNJ-67856633-ZAF (referred as JNJ-67856633) is an orally bioavailable, potent, and selective first-in-class mucosa-associated lymphoid tissue lymphoma translocation protein-1 (MALT1) inhibitor. JNJ-67856633 binds to an allosteric site on MALT1 with a mixed-type mechanism. Ibrutinib is a first-in-class, orally administered, potent, orally administered covalently binding small-molecule inhibitor of Bruton's tyrosine kinase (BTK), as well as interleukin-2-inducible kinase (ITK), a tyrosine protein (Tec) kinase family member present in T cells. The doses will be escalated in the study and one or more recommended Phase 2 dose (RP2Ds) of JNJ-67856633 will be determined. The study is divided into 3 periods: a screening phase, a treatment phase, and a post-treatment follow-up phase. Efficacy assessments will include radiographic image assessments, positron emission tomography scan, bone marrow assessment, endoscopy etc. Safety assessment like physical examination, vital signs, electrocardiogram (ECG), eastern cooperative oncology group (ECOG) performance status, and adverse events monitoring will be performed during the study. Total duration of the study will be up to 2 years and 9 months.
The purpose of this study is to determine the safety and recommended Phase 2 dose (RP2D) of JNJ-67856633 and ibrutinib in combination in participants with B cell non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukemia (CLL).
