What was measured

Percentage of participants with CR, defined as normal serum immunoglobulin M (IgM) levels, disappearance of monoclonal protein by immunofixation, and negative cryoglobulinemia if cryoglobulinemia was positive at baseline, or VGPR, defined as ≥90% reduction in serum IgM level from baseline or normal serum IgM values.

Analysis population: Intent To Treat (ITT) Analysis Set

Groups in this outcome

Arm A: Ibrutinib

Participants diagnosed with WM with mutated MYD88 gene received 420 mg Ibrutinib once daily orally until progressive disease, unacceptable toxicity, death, withdrawal of consent, or study termination by sponsor

Arm B: Zanubrutinib

Participants diagnosed with WM with mutated MYD88 gene received 160 mg zanubrutinib twice daily orally until progressive disease, unacceptable toxicity, death, withdrawal of consent, or study termination by sponsor
