Inclusion Criteria
- Participants must meet the following criteria on screening examination to be eligible to participate. Screening evaluations including consent, physical exam, and laboratory assessments will be done within 30 days prior to Cycle 1 Day 1. Bone marrow biopsy &aspirate, skin (fat) biopsy, EMG, and CT C/A/P will be done within 90 days prior to Cycle1 Day 1. - Presence of an IgM monoclonal paraprotein on serum immunofixation electrophoresis - Diagnosis of IgM MGUS or Waldenstrӧm macroglobulinemia using the criteria from Owen RG, Treon SP, Al-Katib A, Fonseca R, Greipp PR, McMaster ML, et al.Clinicopathological definition of Waldenstrom's macroglobulinemia: consensus panel recommendations from the Second International Workshop on Waldenstrom's Macroglobulinemia.

Note: Patients with presence of HBcAb, but absence of HBsAg, are eligible if HBV DNA is undetectable and if they are willing to undergo monitoring for HBV reactivation throughout the study. - Patients with presence of HCV antibody are eligible if HCV RNA is undetectable and if they are willing to undergo monitoring for HCV reactivation. - No significant infection (eg bacterial, viral, or fungal) at study entry - Inability to swallow pills - Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements - Unwillingness or inability to comply with the protocol

Experimental ACALABRUTINIB + RITUXIMAB/BIOSIMILAR |
Acalabrutinib and rituximab (or biosimilar) with be contained in the treatment regimen. Acalabrutinib will be administered twice daily, with 28 consecutive days defined as a treatment cycle. Acalabrutinib will be administered for 48 cycles or until disease progression or unacceptable toxicity. Rituximab will be administered on Days 1, 8, 15, and 22 of Cycles 1 and 4. Participants will have study visits every cycle for cycles 1-6, then every 3 cycles, with the next visit at Cycle 9, then C12, C15, etc. Participants will continue acalabrutinib until disease progression or intolerable adverse effect develops. They will be followed for up to 2 years after completion of 48 cycles of treatment or until death |

Detailed Description
This research study involves an experimental drug combination of a targeted therapy and a CD20 antibody. The names of the study drugs involved in this study are/is: - Acalabrutinib - Rituximab or similar CD20 antibody The research study procedures include screening for eligibility and study treatment including evaluations and follow up visits. The study treatment for up to 4 years and will be followed for 2 years after completion of study treatment. It is expected that about 33 people will take part in this research study. This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational drug to learn whether the drug works in treating a specific disease. "Investigational" means that the drug is being studied. The U.S. Food and Drug Administration (FDA) has not approved acalabrutinib for this specific disease but it has been approved for other uses. The U.S. Food and Drug Administration (FDA) has not approved rituximab or similar CD20 antibody for this specific disease but it has been approved for other uses. - Acalabrutinib is a targeted therapy that blocks a type of protein called Bruton Tyrosine Kinase (BTK) that helps cells live and grow. By blocking BTK, acalabrutinib may kill abnormal cells or stop them from growing. It has been FDA approved for mantle cell lymphoma (MCL). - Rituximab, or biosimilar, is a type of therapy called an antibody that attacks CD20, a protein found on B-cells. Rituximab is approved by the FDA for treating non-Hodgkin lymphoma (NHL). Rituximab is often used to treat WM and IgM MGUS neuropathies. Biosimilars are FDA approved drugs that have been determined to be interchangeable with the original drug.
