Inclusion Criteria	Exclusion Criteria
* Subjects aged ≥ 18 years. * ECOG Performance Status ≤ 2. * Histologically confirmed marginal zone lymphoma, including splenic, nodal, and extranodal sub-types per the enrolling institution. * Subjects must have an indication for treatment. * No prior systemic therapy for MZL except for the following: * Prior antibiotic therapy for H. pylori, C. psittaci, and B. burgdorferi * Prior antiviral therapy for HCV * Subjects with gastric MALT lymphoma must be H. pylori negative or have failed a trial of H. pylori eradication * Subjects with localized MALT lymphoma must be ineligible for, have refused or failed radiation therapy (washout period of 14 days) * Adequate organ function as defined as: * Hematologic: * Absolute neutrophil count ≥ 750 cells/mm3 (≥ 0.75 x 10\^9/L) independent of G-CSF support, unless there is documented bone marrow involvement or splenomegaly with ensuing cytopenia in which case ANC of 500 cells/mm3 (0.5 x 10\^9/L) is permissible. Also, there should be no evidence of myelodysplasia or hypoplastic bone marrow * Platelet count ≥ 50,000/mm3 (≥50 x 10\^9/L) independent of transfusion support unless there is documented bone marrow involvement in which case platelet count of ≥30,000 cells/mm3 (≥30 x 10\^9/L) is permissible. Subjects must be responsive to transfusion support if given for thrombocytopenia and subjects refractory to transfusion support are not eligible. Also, there should be no evidence of myelodysplasia or hypoplastic bone marrow. * Note: The platelet count threshold in the current study (≥50,000 cells/mm\^3 or ≥50 x 10\^9/L) is lower than normal threshold (≥75,000 cells/mm\^3 or ≥75 x 10\^9/L) as the majority of MZL subjects have lower than normal platelets due to splenomegaly and or autoimmune phenomena (which are related to the underlying lymphoma) and hence the lower than normal platelet count threshold for study entry * Hemoglobin ≥ 8 g/dL independent of transfusion support unless there is documented bone marrow involvement or splenomegaly with ensuing cytopenia in which case hemoglobin of ≥7 g/dL (≥70 g/L) is permissible. Subjects must be responsive to transfusion support if given for anemia and subjects refractory to transfusion support are not eligible. Also, there should be no evidence of myelodysplasia or hypoplastic bone marrow. * Hepatic: * AST(SGOT)/ALT(SGPT) ≤ 3 × institutional ULN ----Subjects with liver metastases will be allowed to enroll with AST and ALT levels ≤ 5 x ULN. * Renal: Estimated creatinine clearance ≥ 30 mL/min by Cockcroft-Gault formula: * aPPT or PT or INR ≤ 1.5 X ULN * Life expectancy of \>3 months, in the opinion of the investigator * For female subjects: Negative pregnancy test or evidence of post-menopausal status.

Subjects with positive anti-HBc and negative HBV DNA should be on prophylactic nucleo(t)side analogue therapy to prevent reactivation with serial HBV DNA PCR monitoring per section 6.6.9. * Known active cytomegalovirus (CMV) infection * Active uncontrolled auto-immune cytopenia (e.g., autoimmune hemolytic anemia \[AIHA\], idiopathic thrombocytopenic purpura \[ITP\]) for which new therapy was introduced or existing therapy was escalated within the 4 weeks prior to study enrollment to maintain adequate blood counts * Medical, psychiatric, cognitive, or other conditions that may compromise the subject's ability to understand the subject information, give informed consent, comply with the study protocol or complete the study. * Known prior severe hypersensitivity to investigational product (IP) or any component in its formulations (NCI CTCAE v5.0 Grade ≥ 3).
