This study is to evaluate the safety, efficacy and clinical benefit of BGB-3111 (Zanubrutinib) vs ibrutinib in participants with MYD88 Mutation Waldenström's Macroglobulinemia.

Official Title

A Phase 3, Randomized, Open-Label, Multicenter Study Comparing the Efficacy and Safety of the Bruton's Tyrosine Kinase (BTK) Inhibitors BGB-3111 and Ibrutinib in Subjects With Waldenström's Macroglobulinemia (WM)


This open-label, randomized study will compare the efficacy and safety of the Bruton's Tyrosine Kinase (BTK) inhibitors BGB-3111 and ibrutinib in participants with Waldenström's Macroglobulinemia who require therapy. Participants will have baseline bone marrow samples assayed for sequencing of the MYD88 gene. Approximately 188 participants with the MYD88 mutation will be enrolled onto Cohort 1 and randomized to receive 160 mg BGB-3111 PO BID (treatment Arm A) or to receive 420mg ibrutinib QD (treatment Arm B) until disease progression or unacceptable toxicity. Participants with MYD88 wild type will be enrolled to Cohort 2 and will receive 160 mg BGB-3111 PO BID (treatment Arm C) until disease progressive disease (PD) or unacceptable toxicity, withdrawal of consent, loss to follow-up, or study termination by Sponsor.
