About this study

In Waldenström's macroglobulinemia (WM) chemotherapy induces only low CR/VGPR rates and response duration is limited. In addition, WM patients are often elderly, partly not tolerating chemotherapy related toxicities. Thus, innovative approaches are needed which combine excellent activity and tolerability in WM. Chemotherapy-free approaches are highly attractive for this patient group. Based on its high activity and favorable toxicity profile in indolent B-NHL such as CLL, Venetoclax was approved for the treatment of this diseases by the FDA and the European Medicines Agency (EMA). First data in relapsed/refractory WM have documented high activity and low toxicity of Venetoclax also in WM, including patients with prior Ibrutinib treatment or patients carrying CXCR4 mutations. Ibrutinib itself has high activity and a relatively low toxicity profile in WM, but has also major disadvantages: the main disadvantage is the need to apply this drug continuously. Furthermore, Ibrutinib efficacy depends largely on the genotype with a substantial drop in major responses and PFS in the presence of CXCR4 mutations and non-mutated MYD88. In particular the need of continuous treatment for Ibrutinib has prevented that Ibrutinib has become the standard of care outcompeting conventional Rituximab/chemotherapy. This is reflected in current guidelines such as the NCCN and the ESMO guidelines, which still see immunochemotherapy as a backbone of treatment, largely because of the advantage of a timel…
