2. Histologically confirmed diagnosis of MZL including splenic, nodal, and extranodal subtypes
3. Previously received one or more lines of therapy including at least one CD20-directed regimen (either as monotherapy or as chemoimmunotherapy) with documented failure to achieve at least partial response or documented progressive disease (PD) after, the most recent systemic treatment
4. Current need for systemic therapy for MZL
5. Measurable disease by computed tomography (CT) or magnetic resonance imaging (MRI)
6. Eastern Cooperative Oncology Group (ECOG) of 0-2
7. Life expectancy ≥ 6 months
8. Adequate bone marrow function
9. Adequate organ function
10. Male and female participants must use highly effective methods of contraception

Key Exclusion Criteria:

1. Known transformation to aggressive lymphoma, eg, large cell lymphoma
2. Clinically significant cardiovascular disease
3. Prior malignancy within the past 2 years, except for curatively treated basal or squamous cell skin cancer, superficial bladder cancer, carcinoma in situ of the cervix or breast, or localized Gleason score 6 prostate cancer
4. History of severe bleeding disorder such as hemophilia A, hemophilia B, von Willebrand disease, or history of spontaneous bleeding requiring blood transfusion or other medical intervention

6. Severe or debilitating pulmonary disease
7. Active fungal, bacterial and/or viral infection requiring systemic therapy
8. Known central nervous system involvement by lymphoma
9. Known infection with HIV, or serologic status reflecting active viral hepatitis B (HBV) or viral hepatitis C (HCV) infection
10. Major surgery within 4 weeks of the first dose of study drug
11. Prior treatment with a Bruton's tyrosine kinase (BTK) inhibitor
12. Pregnant or lactating women
