must be >15 mm in the longest diameter or >10 mm in the short axis); IgM =450 mg/dL;
or bone marrow infiltration of 10%

- Has fresh bone marrow aspirate or a lymph node biopsy for biomarker analysis at
Screening or a lymph node biopsy from an archival

Summary
Brief summary
The purpose of this study is to evaluate the safety and efficacy of nemtabrutinib (formerly
ARQ 531) in participants with hematologic malignancies of chronic lymphocytic leukemia (CLL)/
small lymphocytic lymphoma (SLL), Richter's transformation, marginal zone lymphoma (MZL),
mantle cell lymphoma (MCL), follicular lymphoma (FL), and Waldenström's macroglobulinemia
(WM).
