New study tracks targeted drug zanubrutinib in rare blood cancer
NCT ID NCT05640102
First seen Jun 27, 2026 · Last updated Aug 07, 2026 · Updated 1 time
Summary
This study is tracking how well the drug zanubrutinib works and its safety in people with Waldenström macroglobulinemia, a rare blood cancer. Researchers are especially interested in patients with specific genetic mutations and those from racial and ethnic minority groups. The study will collect information from medical records and follow participants over time to see how they respond to treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- zanubrutinib (a targeted cancer drug, also called Brukinsa)
- What this could lead to
- If successful, this study could confirm that zanubrutinib is effective and safe for a broader range of patients with Waldenström macroglobulinemia, including those from racial and ethnic minority groups.
- What could go wrong
- This is an observational study, not a controlled trial, so results may be less definitive. It is also relatively small (111 participants) and focuses on a rare blood cancer, so findings may not apply to everyone.
This is an AI summary of the original study and may miss details. Read our disclaimer.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Clinical and definitive histologic diagnosis of WM * Measurable disease, 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: * Evidence of disease transformation before the first dose of zanubrutinib * Evidence of other non-Hodgkin Lymphoma (NHL) subtypes * Prior or concurrent active malignancy ≤ 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
