Group Intervention Description Part 1a (Monotherapy Dose Escalation) BGB-16673 Dose escalation in specific subtypes of non-Hodgkin lymphoma (NHL), including relapsed or refractory (R/R) marginal zone lymphoma (MZL), R/R follicular lymphoma (FL) Grades 1, 2, and 3a, R/R mantle cell lymphoma (MCL), R/R chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), R/R diffuse large B-cell lymphoma (DLBCL), R/R Richter's transformation (RT), and R/R Waldenström macroglobulinemia (WM), to evaluate the safety and tolerability of BGB-16673. Part 1f (Additional Monotherapy Safety Expansion in BTKi Naive B-Cell Malignancies) BGB-16673 Participants with CLL/SLL, MCL, WM, MZL, or Richter's transformation to DLBCL who have not received a prior BTKi (either covalent or noncovalent) will be enrolled at selected dose levels. Phase 2 (Monotherapy Expansion) BGB-16673 Cohorts of participants with R/R CLL/SLL, R/R MCL, R/R WM, R/R MZL, R/R FL, R/R RT, and R/R DLBCL will be enrolled to receive the RDFE(s) identified in Phase 1 to further evaluate the safety and efficacy of BGB-16673. Part 1b (Monotherapy Safety Expansion) BGB-16673 Participants with R/R MZL, MCL, CLL/SLL, and WM will be enrolled at selected doses to help determine the recommended dose(s) for expansion (RDFE(s)) for BGB-16673. Part 1c (Additional Monotherapy Safety Expansion) BGB-16673 Additional safety data will be collected from participants with R/R MZL, WM, RT, DLBCL, or FL to confirm the RDFE(s) of BGB-16673 for those with non-CLL/SLL/MCL histologies. Part 1e (Japan-only Cohort) BGB-16673 Japanese participants with R/R MZL, FL, MCL, CLL/SLL, and WM will be enrolled at selected RDFE(s) to assess the safety and tolerability of BGB-16673. Part 1d (Additional Monotherapy Safety Expansion in R/R CLL/SLL) BGB-16673 Participants with R/R CLL/SLL will be enrolled at selected RDFE(s) to generate additional safety and efficacy data for BGB-16673.
