A Study to Evaluate Long-term Safety of Zanubrutinib Regimens in Participants With B-Cell Malignancies Who Participated in BeiGene Parent Studies of Zanubrutinib

The purpose of this study is to learn about the long-term safety and effectiveness of zanubrutinib in people with B-cell cancers who took part in an earlier zanubrutinib study. Participants continued receiving zanubrutinib if they were still benefiting from it, or they might have taken part in long-term follow-up after treatment. Information collected in this study will help health authorities better understand the long-term effects of zanubrutinib.
