Observational Study Evaluating the Efficacy and Safety of Zanubrutinib in Participants With Waldenström Macroglobulinemia

Recruiting
Conditions
Waldenstrom Macroglobulinemia
Interventions
Registration Number
NCT05640102
Lead Sponsor
BeiGene
Brief 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.

Target Recruitment

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

Primary Outcome Measures
NameTimeMethod
Major Response Rate (MRR)Up to approximately 4 years

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)

Secondary Outcome Measures
NameTimeMethod
Number of Participants with Treatment-emergent Adverse EventsUp to approximately 5 years
VGPR+ RateUp to approximately 5 years

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

Overall Response Rate (ORR)Up to approximately 5 years

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

Duration of Response (DOR)Up to approximately 5 years

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
