What was measured

DOR: duration from date of initial documentation of response (PR/better) to date of first documented progressive disease(PD), death or date of censoring if applicable, for responders (PR/better), as assessed by investigator. VGPR/PR: \>=90% reduction or normal serum IgM values (for VGPR) and \>=50% (for PR) reduction of serum IgM, with reduction in lymphadenopathy/splenomegaly if present at baseline. PD(at least 1): \>=25% IgM increase in serum IgM with \>=500 milligrams per deciliters(mg/dL) increase from nadir(lowest serum IgM value at any time from baseline), confirmation needed if IgM was sole PD criterion; new lymph nodes \>1.5 centimeters(cm), \>=50% increase in nadir in sum of product of diameters; 50% increase in longest diameter of previously identified node \>1cm in short axis; new splenomegaly; new extranodal disease; new/recurrent bone marrow involvement; new symptomatic disease(pleural effusion/Bing Neel syndrome/amyloidosis/light chain deposition/paraprotein mediated disorder).

Analysis population: Analysis population included responders in all treated analysis set who achieved PR or better.

Groups in this outcome

Ibrutinib 420 mg

Participants with relapsed or refractory waldenstrom's macroglobulinemia received ibrutinib 420 milligrams (mg) (3\*140 mg capsules) orally once daily from Day 1 of Week 1 until disease progression, unacceptable toxicity, whichever occurs first.
