The purpose of this study is to evaluate the long-term safety of treatment regimens with the targeted therapy drug zanubrutinib in people with B-cell malignancies who have participated in a previous clinical trial for zanubrutinibAn Open-label, Multi-center, Long-term Extension Study of Zanubrutinib (BGB-3111) Regimens in Patients With B-cell Malignancies

Clinical summary


Eligible participants will receive zanubrutinib (160mg twice daily or the last dose level received in the BeiGene parent study).

Participants in Australia who participated in a parent study that involved combination therapy of zanubrutinib and tislelizumab will receive zanubrutinib (160mg twice daily, or the last dose level received in the BeiGene parent study) plus tislelizumab (200mg every three weeks).


This trial is treating patients with B-cell malignancies who are either currently participating, or recently participated, in a BeiGene parent study

  4. Zanubrutinib-naive patient:

    Must meet the following criteria ≤ 15 days before first dose of study drug:

    1. Platelets ≥ 50,000/mm3
    2. Absolute neutrophil count ≥ 750/mm3
    3. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 3 x upper limit of normal
    4. Serum total bilirubin ≤ 3 x upper limit of normal (not required for Gilbert Syndrome)

  2. Uncontrolled active systemic infection or recent infection requiring parenteral anti-microbial therapy
  3. Life-threatening illness, medical condition or organ system dysfunction which, in the investigator's opinion, could compromise the participant's safety, interfere with the absorption or metabolism of zanubrutinib, or put the study outcomes at undue risk
