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

CR108877

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).
