Zanubrutinib, Ixazomib and Dexamethasone in Patients With Treatment Naive Waldenstrom's Macroglobulinemia

Summary

This study aims to evaluate the efficacy of BTK inhibitor Zanubrutinib combined with Ixazomib and Dexamethasone (ZID) for the newly diagnosed Waldenstrom Macroglobulinemia. This ZID regimen will be given up to 24 months and stopped for observation. We propose this combination will improve the deep remission (≥VGPR) compared to single Zanubrutinib or IRD regimen and can be a time-limited regimen which will reduce the life-time therapy and benefit the patients.
