Efficacy of First Line B-RI for Treatment Naive Waldenström's Macroglobulinemia
Summary
In Waldenström macroglobulinemia (WM) conventional chemotherapy induces only low complete remission (CR) rates and responses of short duration compared to other indolent lymphomas. Thus innovative approaches are needed which combine excellent activity and tolerability in patients with WM, who are mostly of advanced age. The immunochemotherapy DRC (dexamethasone, rituximab, cyclophosphamide) was shown to be highly effective in patients with WM without inducing major hematological toxicities. On the other hand the proteasome inhibitor bortezomib showed substantial activity as a single agent in WM with only very few side effects when given in a weekly schedule. Recent data confirmed high activity with low toxicity for ibrutinib in relapsed WM patients as single agent therapy. Based on these observations it is the aim of this study to investigate the efficacy and toxicity of the chemotherapy-free combination bortezomib, rituximab, ibrutinib (B-RI) in treatment naïve WM patient.
