Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Based on this the hypothesis is that timely fixed application of the combination of Venetoclax and Rituximab induces significantly superior treatment outcomes compared to chemotherapy and Rituximab (DRC) in patients with treatment naïve WM, regardless of the genotype. A first indication for this assumption in the proposed trial will allow the performance of confirmatory phase 3 trials that might change the standard of care in WM.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Based on this the hypothesis is that timely fixed application of the combination of Venetoclax and Rituximab induces significantly superior treatment outcomes compared to chemotherapy and Rituximab (DRC) in patients with treatment naïve WM, regardless of the genotype. A first indication for this assumption in the proposed trial will allow the performance of confirmatory phase 3 trials that might change the standard of care in WM.
This study is an International phase II explorative, multicenter, open label, and randomized trial.
The study will consist of an open labeled, stratified 1:1 randomization between Arm A and Arm B for de novo WM patients in need of treatment (phase II). Stratification factors are MYD88 and CXCR4 status (positive vs. negative). A stratified central block randomization will be used. The central randomization service will be used to avoid predictability of the treatment arm.
The primary goal of this study is to explore the efficacy of Venetoclax plus Rituximab versus Dexamethasone/Cyclophosphamide/Rituximab in the treatment of de novo WM patients (Arm A vs. Arm B).
80 patients are planned to be recruited for this study at approcimately 30 sites in Germany, Greece and France.
