A Phase 2 Clinical Trial to Evaluate Zanubrutinib Combined With BR (Bendamustine/Rituximab) Regimen in Subjects With Newly-diagnosed Waldenström's Macroglobulinemia (CZ-WM01)

September 12, 2023 updated by: Juan Du, Shanghai Changzheng Hospital

A Prospective, Open-label, Multicenter Study of Zanubrutinib Combined With BR (Bendamustine/Rituximab) Regimen in Subjects With Newly-diagnosed Waldenström's Macroglobulinemia

This was a single-arm, multicenter, Phase 2 study to evaluate the efficacy of zanubrutinib combined with BR (Bendamustine/Rituximab) regimen in Chinese participants with newly-diagnosed Waldenström's macroglobulinemia who exhibited one or more of the criteria for requiring treatment based on consensus guidelines from the 11th International Workshop on Waldenström's Macroglobulinemia (IWWM). The investigators propose this combination will improve the deep remission compared to single Zanubrutinib or BR regimen and can be a time-limited regimen which will reduce the life-time therapy and benefit the patients.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study comprised an initial screening phase (up to 7 days), a single-arm treatment phase, and a follow-up phase. Subjects with newly-diagnosed Waldenström's macroglobulinemia can participate if all eligibility criteria are met. The participants will receive bendamustine and rituximab for 6 28-day cycles. Bendamustine will be given intravenously at 70-90 mg/m2 on days 1 and 2 of each cycle. Rituximab will be given on day 1 of each cycle (375 mg/m2 intravenously), Zanubrutinib will be given orally 160mg Bid per day, up to 12 months. The participants with WM will also have disease assessment with Lymph node ultrasound and abdominal ultrasound each cource, serum IgM, serum protein electrophoresis (SPE), immunofixation (IFA), and viscosity assessments will be measured serially. A bone marrow aspiration and biopsy flow cytometry examination will be done before treatment and at response assessment at cycle 6 and 12. Durability of response will also be assessed every 3 months after treatment.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study
