Overview

The combination of zanubrutinib, bendamustine, and rituximab (often abbreviated as ZBR) is a therapeutic regimen being investigated for the treatment of certain blood cancers. This combination brings together a Bruton tyrosine kinase (BTK) inhibitor (zanubrutinib) with a chemotherapy agent (bendamustine) and an anti-CD20 monoclonal antibody (rituximab). The ZBR regimen has shown promising results in clinical trials, particularly for Waldenström macroglobulinemia (WM) and chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL). In newly diagnosed symptomatic WM patients, the ZBR regimen achieved significant deep remission rates with manageable adverse events. In clinical trials, the combination is typically administered as follows: - Zanubrutinib: 160 mg twice daily, orally, for up to 12 months - Bendamustine: 70 mg/m² intravenously on days 1 and 2 of each cycle - Rituximab: 375 mg/m² intravenously on day 1 of each cycle Treatment is usually administered for 6 cycles.
