ListOutcomeTime frameDescription
PrimaryObjective Response Rate (ORR)Up to 48 months
ORR was defined as the percentage of participants achieving complete response (CR), very good partial response (VGPR), partial response (PR) and minimal response (MR) on treatment based on IWWM-11 criteria.
SecondaryComplete Response RateUp to 48 months
Complete response rate was defined as the percentage of participants achieving complete response (CR) on treatment based on IWWM-11 criteria, defined as having resolution of WM related symptoms, normalization of serum IgM levels with complete disappearance of IgM paraprotein by immunofixation, and resolution of any adenopathy or splenomegaly. A complete response requires reconfirmation demonstrating normal serum IgM levels, and absence of IgM paraprotein by immunofixation by a measurement repeated at least 2 weeks later.
SecondaryVery Good Partial Response RateUp to 48 months
Very good partial response rate was defined as the percentage of participants achieving very good partial response (VGPR) on treatment based on IWWM-11 criteria, defined as ≥90% reduction in serum IgM levels, or normalization of serum IgM levels with persistent IgM monoclonal spike in SPEP or immunofixation.
SecondaryPartial Response RateUp to 48 months
Partial response rate was defined as the percentage of participants achieving partial response (PR) on treatment based on IWWM-11 criteria, Partial response (PR) is defined as achieving a ≥50% to \<90% reduction in serum IgM levels.
SecondaryMinimal Response RateUp to 48 monthsMinimal response rate was defined as the percentage of participants achieving minimal response (MR) on treatment based on IWWM-11 criteria, defined as ≥25 to \<50% reduction in serum IgM levels.
SecondaryStable Disease RateUp to 48 months
Stable disease rate was defined as the percentage of participants achieving stable disease (SD) on treatment based on IWWM-11 criteria, defined as \<25% reduction to \<25% increase in serum IgM levels.
SecondaryProgressive Disease RateUp to 48 months
Stable disease rate was defined as the percentage of participants achieving progressive disease (SD) on treatment based on IWWM-11 criteria, defined as defined as a≥25% increase in serum IgM level occurring with an absolute increase of at least 500 mg/dL from nadir or progression of clinically significant disease-related symptom(s). Reconfirmation of the initial IgM increase is required when IgM is the sole criterion for progressive disease confirmation. Death from any cause or initiation of a new anti-neoplastic therapy will also be considered a progression event. Additionally, a new lesion (\>1.5 cm in any axis) or unequivocal evidence of an increase by \>50% in any axis to \>1.5 cm in size of previously involved extramedullary disease sites from their nadir measurement. Development of Bing Neel syndrome, amyloidosis, or other extramedullary disease manifestations, as well as disease transformation will be considered as progressive events.
SecondaryTime to Response (TTR)Up to 48 monthsTTR is the time from treatment initiation until the attainment of a minor response.
SecondaryTime to Major Response (TTMR)Up to 48 monthsTTMR is the time from treatment initiation until attaining a PR or better.
SecondaryMedian Progression-free Survival (PFS)Up to 48 monthsPFS based on Kaplan-Meier methodology is defined as the time from treatment initiation until disease progression, death from any cause, or last follow-up visit.
SecondaryTime to Next Treatment (TTNT)Up to 48 monthsTTNT is the time between treatment initiation and initiation of the next therapy.
SecondaryMedian Overall Survival (OS)Up to 6 yearsOS is defined as the time from treatment initiation until death from any cause or last follow-up visit
SecondaryBone marrow responseUp to 48 monthsAbsolute change in bone marrow burden of disease from baseline
SecondaryOverall Response Rate Among Participants Without MYD88 MutationsUp to 48 months

SecondaryOverall Response Rate Among Participants With MYD88 MutationsUp to 48 months
Overall Response Rate in participants who tested positive for a MYD88 mutation= Minor response (\>25%-50% reduction in serum IgM from baseline) + Partial Response (\>50-90% reduction in serum IgM from baseline) + Very Good Partial Response (\>90% reduction in serum IgM from baseline) + Complete Response (resolution of all symptoms, normalization of serum IgM with disappearance of IgM paraprotein, resolution of any adenopathy or splenomegaly).
