Efficacy of First Line DRC +/- Bortezomib for Patients With Waldenström's Macroglobulinemia

Summary

In Waldenström macroglobulinemia (WM) conventional chemotherapy induces only low 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. Based on these observations it is the aim of this study to test whether the efficacy of the well tolerated DRC regime can be further improved by adding Bortezomib.
