Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Concomitantly, participants will receive 100 mg of the investigational product, Acalabrutinib, orally for 1 year (365 days) at 100 mg BID. Patients will have pre-treatment computed tomography (CT) scans, and CT scans at 7, 12 and 18 months. Best objective response will be documented using the criteria from the Sixth International Workshop on Waldenstrom's Macroglobulinemia. Assessment of metabolic uptake by positron emission tomography (PET) scan is not considered appropriate for WM as WM usually do not take up fluorodeoxyglucose (FDG). Patients with WM will also have disease assessed using measurements of serum IgM, serum protein electrophoresis (SPE), immunofixation (IFA), and viscosity assessments measured serially. A bone marrow aspiration and biopsy will be done before treatment and at response assessment at cycle 6 and will be repeated if positive. Durability of response will also be assessed at 18 months.
Participants will be followed by extended follow-up by telephone for up to 6 years to obtain data on the secondary endpoints.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Have not received any systemic treatment for the disease (plasmapheresis, involved field radiation or corticosteroids (for contrast enhanced studies and to acutely control disease-related symptoms or as chemotherapy premedication)) are allowed.
3. Be willing and able to provide written informed consent for the trial.
4. Male or female \>=18 years of age on day of signing informed consent and of any racial or ethnic group.
5. Have at least one measurable site of disease based on Cheson Criteria (Appendix C) using standard CT imaging or a quantifiable IgM paraprotein that is two times the upper limit of normal.
6. Have symptomatic or impending symptomatic disease or evidence of hematologic or biochemical compromise related to the lymphoma.
7. Have a performance status of 0-2 on the ECOG Performance Scale.
8. Demonstrate adequate organ function as defined in Table 2. Adequate organ function must be confirmed within 72 hours prior to start of treatment. Patients with abnormal liver enzymes of up to 5 times the upper limit of normal and/or reduced glomerular filtration rate (GFR) or estimated glomerular filtration rate (eGRF) of ≥ 30 mL/min/1.73 m2can be considered for enrolment.
9. A life expectancy \> 6 months in the opinion of the investigator.
10. Female subject of childbearing potential should have a negative serum pregnancy test within 72 hours prior to receiving the first dose of study medication (day 1).
11. Female subjects of childbearing potential should be willing to use 2 highly effective methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study until 2 days post-last dose of acalabrutinib, 4 weeks post-last dose of bendamustine, and 12 months post-last dose of rituximab. Subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for \> 1 year.
12. Male subjects should agree to use a highly-effective method of contraception starting with the first dose of study therapy until 2 days post-last dose of acalabrutinib, 6 months post-last dose of bendamustine, and 12 months post-last dose of rituximab.
13. Ability to comply with protocol requirements.
