Study summary

This is a hybrid (retrospective and prospective) non-interventional registry study to further describe the clinical profile of zanubrutinib in Waldenström macroglobulinemia (WM) participants with and without specific mutations and from racial and ethnic minority groups. Data collected from this registry study will be used to better understand the clinical benefit and safety of zanubrutinib for the treatment of participants in these populations.

Study population

Adult participants with WM who are either already receiving or are planned to start treatment with zanubrutinib

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Clinical and definitive histologic diagnosis of WM
  • , as defined by a serum immunoglobulin M (IgM) level > 0.5 g/dL at the time of zanubrutinib initiation
  • Started treatment with zanubrutinib, has been treated with zanubrutinib, or is planned to be prescribed zanubrutinib for the treatment of WM
  • Bone marrow specimens with central MYD88 test results of:

    1. Cohort 1: MYD88 L265P mutation; enrollment of TN participants will be stopped in each racial and ethnic participant group when the required numbers of participants in the group are met
    2. Cohort 2: non-L265P MYD88 mutation(s) and MYD88WT

Exclusion criteria

Exclusion Criteria:

  • Evidence of disease transformation before the first dose of zanubrutinib
  • Evidence of other non-Hodgkin Lymphoma (NHL) subtypes
  • Prior or concurrent active ≤ 2 years before the first dose of zanubrutinib, except for malignancies that, in the investigator's opinion, will not obscure the interpretation of safety or efficacy results
  • Concurrent participation in another therapeutic clinical study while receiving zanubrutinib, although the participant may be eligible depending on the status of the interventional study after discussion with the Medical Monitor or designee on an individual basis
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Measurable disease

The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.

The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

What researchers measure

Primary outcomes

  1. Major Response Rate (MRR)

    MRR is defined as the proportion of participants achieving either complete response (CR), very good partial response (VGPR), or partial response (PR) as determined by the investigator using an adaptation of the response criteria updated at the Sixth International Workshop on WM (IWWM)

    Time frame: Up to approximately 4 years

Secondary outcomes

  1. VGPR+ Rate

    VGPR+ rate is defined as the proportion of participants achieving either CR or VGPR

    Time frame: Up to approximately 5 years

  2. Overall Response Rate (ORR)

    ORR is defined as the proportion of participants achieving either CR, VGPR, PR, or minor response (MR)

    Time frame: Up to approximately 5 years

  3. Duration of Response (DOR)

    DOR is defined as the time from the first determination of response (CR, VGPR, or PR) until first documentation of or death, whichever comes first

    Time frame: Up to approximately 5 years

  4. Number of Participants with Treatment-emergent Adverse Events

    Time frame: Up to approximately 5 years

Individual participant data

Plan to share: Yes — BeiGene shares data on completed studies responsibly and provides qualified scientific and medical researchers access to data and supporting documentation for clinical trials in dossiers for medicines and indications after submission and approval in the United States, China, and Europe. Clinical trials supporting subsequent local approvals, new indications, or combination products are eligible for sharing once corresponding regulatory approvals are achieved. BeiGene shares data only when permitted by applicable data privacy and security laws and regulations, when it is feasible to do so without compromising the privacy of study participants, and other considerations. Qualified researchers with appropriate competencies who are engaged in novel scientific research may submit a request for participant-level data with a research proposal for BeiGene review. Research teams must include a biostatistician and sign a Data Sharing Agreement prior to receiving access to clinical trial data.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 7, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
