Overview
The goal of this study is to compare how well sonrotoclax plus zanubrutinib works versus zanubrutinib plus placebo in treating adults with relapsed/refractory (R/R) mantle cell lymphoma (MCL). This study will also look at the safety of sonrotoclax plus zanubrutinib versus zanubrutinib plus placebo.

- Relapsed or refractory disease after the last line of therapy
- Measurable disease defined as ≥ 1 nodal lesion that is > 1.5 cm in longest diameter, or ≥ 1 extranodal lesion that is > 1 cm in longest diameter
- Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 to 2
- Adequate organ function
Exclusion Criteria:
- Prior therapy with B-cell lymphoma-2 inhibitor
- Prior therapy with covalent or non-covalent Bruton tyrosine kinase inhibitor (BTKi) unless the participant was intolerant of non-zanubrutinib covalent or non-covalent BTKi
- Prior autologous stem cell transplantation or chimeric antigen receptor T-cell therapy within 3 months before first dose of study drug
- Prior allogeneic stem cell transplant within 6 months of the first dose of the study drug
