Eligibility
Key inclusion criteria
* Criteria for inclusion:

Patients must meet all of the following inclusion criteria to be eligible for participation in this study:

1. Local confirmed clinicopathological diagnosis of WM in accordance with the consensus panel of the Second International Workshop on WM (Owen 2003).
2. WM patients with symptomatic and measurable disease (defined as presence of serum immunoglobulin M (IgM)>0.5g/dL), requiring treatment as per mSMART guidelines (Kyle 2003): with B symptoms (fever, night sweats, fatigue, night sweats weight loss), progressive lymphadenopathy or splenomegaly, anemia (hemoglobin value of <10 g/dL) or platelet count <100*109/L due to marrow infiltration. Complications such as hyperviscosity syndrome, symptomatic sensorimotor peripheral neuropathy due to WM, systemic amyloidosis related to WM, renal insufficiency related to WM, or symptomatic cryoglobulinemia may also be indications for therapy.
3. For Arm A only: Have received at least one prior therapy for WM. Patient must have either failed (defined as progressing while on or within 6 months of treatment with ibrutinib treatment) or intolerant to ibrutinib.
4. For Arm B only: Previously untreated WM.
5. For Arm C only: Have received at least one prior therapy, relapsed or refractory WM.
6. Adequate hematologic function defined as:

1. ANC =1.0 x 109/L independent of growth factor support within 7 days of the first dose with study drug.
2. Hemoglobin =9 g/dL without transfusion or growth factor support within 7 days of the first dose of study drug.
3. Platelet count = 75 x 109/L without transfusion support within 7 days of the first dose of study drug.
7. Adequate hepatic and renal function defined as:

1. AST and ALT < 2.5 x ULN (upper limit of normal)
2. Glomerular filtration rate (GFR) >30mL/min
3. Bilirubin< 1.5 x ULN
8. PT/INR =1.5 x ULN and PTT (aPTT) =1.5 x ULN.
9. =18 years of age.
10. Eastern Cooperative Oncology Group (ECOG) =1.
11. Life expectancy=3 months.
12. Female subjects who are of non-reproductive potential (i.e., post-menopausal by history-no menses for =2 year; OR history of hysterectomy; OR history of bilateral tubal ligation; OR history of bilateral oophorectomy). Female subjects of childbearing potential must have a negative serum pregnancy test upon study entry.
13. Male and female subjects who agree to use highly effective methods of birth control (e.g.,condoms, implants, injectables, combined oral contraceptives, some intrauterine devices[IUDs], sexual abstinence, or sterilized partner) during the period of therapy and for 30 days after the last dose of study drug and 90 days (males) after the last dose of study drug.

Symptomatic disease meeting at least 1 of the recommendations from the Second International Workshop on Waldenström Macroglobulinemia for requiring treatment (Kyle 2003):

1. Constitutional symptoms documented in the subject's chart with supportive objective measures, as appropriate, defined as one or more of the following disease-related symptoms or signs:

1. Unintentional weight loss =10% within the previous 6 months prior to Screening
2. Fevers higher than 100.5°F or 38.0°C for 2 or more weeks prior to Screening without evidence of infection
3. Night sweats for more than 1 month prior to Screening without evidence of infection
2. Clinically relevant fatigue which is not relieved by rest due to WM
3. Symptomatic hyperviscosity or serum viscosity levels greater than 4.0 centipoises
4. Lymphadenopathy which is either symptomatic or bulky (=5cm in maximum diameter)
5. Symptomatic hepatomegaly and/or splenomegaly and/or organ tissue infiltration
6. Peripheral neuropathy due to WM

14. Serum monoclonal protein >5g/dL, with or without overt clinical symptoms.
15. Any other condition or circumstance that would, in the opinion of the investigator, make the patient unsuitable for participation in the study.
Minimum age

3. For Arm C only:

1. Patients who have previously been treated with ibrutinib or other BTK inhibitor.
2. Disease that is refractory to the last prior rituximab based-therapy defined as either Relapse after the last rituximab-based therapy (<12 months since last dose of rituximab), OR Failure to achieve at least a MR after the last rituximab-based therapy.

4. Known anaphylaxis or IgE-mediated hypersensitivity to murine proteins or to any component of rituximab.
4. Patients with central nervous system involvement (Bing-Neel syndrome), active infection (including active hepatitis B or C virus infection, known human immunodeficiency virus (HIV) positive) or any other serious (unresolved) medical condition.
5. Plasmapheresis <35 days prior to the initiation of study drug. (Note: Subjects with high IgM values or hyper-viscosity symptoms during screening may receive plasmapheresis prior to initiating study drug if the previous plasmapheresis was performed >35 days before the plasmapheresis performed during screening (in order to obtain a true baseline IgM value for efficacy evaluations).
6. Failure to have fully recovered (i.e., =Grade 1 toxicity) from the reversible effects of prior treatment for WM.
7. Significant screening electrocardiogram (ECG) abnormalities including left bundle branch block, 2nd degree atrioventricular (AV) block type II, 3rd degree block, or corrected QT interval (QTc) =470 msec.
8. Unable to swallow tablets or malabsorption syndrome, disease significantly affecting gastrointestinal function, or resection of the stomach or small bowel, symptomatic inflammatory bowel disease or ulcerative colitis, or partial or complete bowel obstruction.

17. Known bleeding disorders (eg, von Willebrand's disease) or hemophilia.
18. History of stroke or intracranial hemorrhage within 12 months prior to enrollment.
