A Study to Investigate Efficacy and Safety of BCL2 Inhibitor Sonrotoclax as Monotherapy and in Combination With Zanubrutinib in Adults With Waldenström Macroglobulinemia
This study will evaluate the safety and efficacy of the BCL2 inhibitor sonrotoclax (BGB-11417) in participants with relapsed/refractory Waldenström's Macroglobulinemia (R/R WM) and in combination with zanubrutinib in adult participants with previously untreated WM.
Study details:
This study will test whether sonrotoclax (BGB-11417) can be used to improve outcomes in participants with Waldenström's Macroglobulinemia (WM) both when used alone in those who have not responded well to conventional treatments and when used in combination with zanubrutinib in those who have not yet received treatment. The main goals of the study are to determine how many participants no longer have evidence of cancer or have some improvement in the signs and symptoms of cancer after treatment, and to determine what adverse events, or side effects, participants might experience. BCL2 is a key protein involved in cell death, and abnormal levels of BCL2 are associated with many cancers.
Blocking the action of BCL2 proteins is a promising approach with potential therapeutic benefits in participants with different types of cancers, including WM. This study will enroll approximately 105 participants. All participants will receive sonrotoclax orally as a tablet.
The study will take place at multiple centers worldwide. The overall time to participate in this study is approximately 5 years.
Eligibility criteria
Researchers look for people who fit a certain description, called eligibility criteria. See if you qualify.
Inclusion criteria
- Clinical and definitive histologic diagnosis of WM.
- Meeting ≥ 1 criterion for treatment according to consensus panel criteria from the 2nd International Workshop on Waldenström's Macroglobulinemia (IWWM).
- For Cohorts 1-3, refractory or relapsed disease at study entry unless participants had intolerance to the most recent therapy. Refractory disease is defined as not attaining at least a major response, or progressing while on or within 6 months of completing therapy. Relapsed disease is defined as attaining at least a major response to therapy and meeting the criteria for disease progression beyond 6 months after completing therapy.
- For Cohort 4, patients must not have received prior therapy for WM (except for plasmapheresis).
- Adequate organ function.
Exclusion criteria
- Central nervous system (CNS) involvement by WM.
- Transformation to aggressive lymphoma, such as diffuse large B-cell lymphoma.
- History of other malignancies ≤ 2 years before study entry.
- Uncontrolled active systemic infection or recent infection requiring parenteral antimicrobial therapy that was completed ≤ 14 days before the first dose of the study drug.

What is the study measuring?
Primary Outcome
| Measure | Description | Time Frame |
|---|---|---|
| Cohort 1: Major Response Rate (MRR) | MRR is defined as the percentage of participants achieving partial response (PR) or better, as assessed by the Independent Review Committee (IRC) per the 11th International Workshop on Waldenström Macroglobulinemia (IWWM-11) WM response criteria. | Up to approximately 4 years |
Secondary Outcome
| Measure | Description | Time Frame |
|---|---|---|
| Cohorts 2 and 3: MRR as assessed by the IRC | MRR is defined as the percentage of participants achieving PR or better. | Up to approximately 5 years |
| All Cohorts: MRR as assessed by the Investigator | MRR is defined as the percentage of participants achieving PR or better. | Up to approximately 5 years |
| Cohorts 1, 2, and 3: Duration of Major Response (DoMR) as assessed by the IRC | DoMR is defined as the time from first determination of major response until first documentation of progression or death, whichever occurs first. | Up to approximately 5 years |
| All Cohorts: DoMR as assessed by the Investigator | DoMR is defined as the time from first determination of major response until first documentation of progression or death, whichever occurs first. | Up to approximately 5 years |
| Cohorts 1, 2, and 3: Complete Response (CR) + Very Good Partial Response (VGPR) as assessed by the IRC | CR + VGPR is defined as the percentage of participants who achieve CR or VGPR. | Up to approximately 5 years |
| All Cohorts: CR + VGPR as assessed by the Investigator | CR + VGPR is defined as the percentage of participants who achieve CR or VGPR. | Up to approximately 5 years |
