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.

Detailed description

As Waldenstrom Macroglobulinemia cells always have two or three components tumor cells, including lymphocyte, Lymphoplasmacytic cells and plasma cells. We designed a oral regimen to target both lymphoma cells (Zanubrutinib) and plasma cells (Ixazomib plus Dexamethasone) to eliminate the tumor cells of WM. We propose this combination will improve the deep remission of WM (≥VGPR) . Zanubrutinib will be given 160mg Bid per day, up to 24 months, Ixazomib 4mg per week and Dexamethasone 20mg per week for three weeks, every 4 weeks one course. ID will be given 6 course as introduction and then one course every 12 weeks for up to 24 months. At the last ID course, Zanubrutinib will be stopped. The last ID course is to prevent the bounce of IgM because of Zanubrutinib discontinue.

DRUG	Zanubrutinib,Ixazomib and Dexamethasone	Zanubrutinib, 160mg orally, twice a day; Ixazomib, 4 mg orally, day 1, 8, 15; Dexamethasone, 20mg orally, days 1, 8, 15；Ixazomib and dexamethasone every 4 weeks of a cycle, with induction of 6 cycles, and then maintain every 12 weeks, up to 6 cycles (96 cycles in total). Zanubrutinib is taken orally twice a day for up to 96 cycles, with a reduction in the last ID cycle. ZID regimen will continue 6 cycles after reaching the maximum response after introduction section.
