• Confirmed diagnosis (per World Health Organization (WHO) guidelines, unless otherwise noted) of one of the following: Marginal Zone Lymphoma (MZL), R/R follicular lymphoma (FL), mantle cell lymphoma (MCL), chronic lymphocytic leukemia and small lymphocytic lymphoma (CLL/SLL), Waldenström macroglobulinemia (WM), R/R diffuse large B-cell lymphoma (DLBCL), or Richter's transformation to DLBCL.

• Participants who have previously received a covalently-binding Bruton´s tyrosine kinase (BTK) inhibitor (BTKi) in any line of therapy must have received treatment with the BTK inhibitor for ≥ 8 weeks (unless reason for discontinuation is intolerance).

• For dose-finding and dose-expansion, participants who had previously received a covalently-binding BTK inhibitor as monotherapy or in combination with other anticancer agents are eligible for the study if they meet any of the following criteria: discontinued the previous BTK inhibitor due to disease progression, experienced disease progression after completing treatment with a BTK inhibitor or discontinued the BTK inhibitor due to toxicity or intolerance.

• Measurable disease by radiographic assessment or serum IgM level (WM only)

• Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 to 2

• Participants enrolling in the dose finding phase of the study may be previously treated with a BTKi or may be naïve to BTKi therapy depending on the diagnosis and country of enrollment; participants with MCL enrolling in the expansion cohorts (Phase 2) must have been treated with a BTKi in a prior line of therapy; CLL/SLL participants, in addition to being treated with a BTKi in a prior line of therapy, must also have received a Bcl-2 inhibitor in a prior line of therapy as well (Phase 2).
