You may be eligible if
Subject aged ≥ 18 years.
Eligible histologies include MCL, MZL (including splenic, nodal, and extranodal sub-types), and WM who received at least one line of prior systemic therapy and FL who received at least two prior lines of systemic therapy
Measurable disease: at least one lesion \>1.5 cm in longest diameter or 1 extranodal lesion \>1 cm in the longest diameter.
--Note: For MZL, isolated splenomegaly and involvement of any biopsy proven extranodal site is considered measurable for this study. For MCL, clonal lymphocyte measured by flow cytometry is considered measurable. For WM, serum IgM level \>0.5 g/dL is considered measurable.
Patients must have an indication for treatment.
* For R/R FL: active disease requiring treatment
* For R/R MCL: active disease requiring treatment

* Recurrent fever, night sweats, weight loss, fatigue
* Hyper viscosity

* Renal:
* Estimated creatinine clearance ≥ 30 mL/min by Cockcroft-Gault formula:
Adequate coagulation, defined as activated partial thromboplastin time (aPTT) or partial thromboplastin time (PTT) and prothrombin (PT) or (international normalized ratio (INR) not greater than 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. The post-menopausal status will be defined as having been amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements apply:
* Women \< 50 years of age:
* Amenorrheic for ≥ 12 months following cessation of exogenous hormonal treatments; and
* Luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution; or
* Underwent surgical sterilization (bilateral oophorectomy or hysterectomy).
* Women ≥ 50 years of age:
* Amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments; or
* Had radiation-induced menopause with last menses \>1 year ago; or
* Had chemotherapy-induced menopause with last menses \>1 year ago; or
* Underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy, or hysterectomy).
Female subjects of childbearing potential and male subjects with a sexual partner of childbearing potential must agree to use a highly effective method of contraception and lactation requirements as described in Section 5.3.1 and 5.3.2.
Subjects must agree to not breastfeed while on treatment or within 1 week of the last dose of tazemetostat or 2 weeks of zanubrutinib.
Ability to swallow oral tablets
Patients or their legal representatives must be able to read, understand, and provide informed consent to participate in the trial.
Willing and capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in the protocol.
Time between prior anticancer therapy and first dose of tazemetostat as below:
* Cytotoxic chemotherapy - At least 21 days
* Non-cytotoxic chemotherapy (e.g., small molecule inhibitor) - At least 14 days
* Monoclonal antibody(ies) - At least 28 days
* Radiotherapy
* At least 14 days from local site radiation therapy
* At least 6 weeks from prior radioisotope therapy
* At least 12 weeks from 50% pelvic or total body irradiation
* High-dose therapy with autologous hematopoietic cell infusion - At least 60 days
* CART cell therapy - At least 60 days
* Moderate CYP3A inhibitors - At least 3 elimination half-lives
* Moderate CYP3A inducers - At least 14 days
* Strong CYP3A inducers or inhibitors - At least 14 days ----Note: Must be able to obtain zanubrutinib and anti-CD20 mAb commercially
Patients who have tested positive for Human Immunodeficiency Virus (HIV)
Known active hepatitis B virus (HBV) or hepatitis C virus (HCV) infection based on criteria below:
* Hepatitis B virus (HBV): Patients with positive hepatitis B surface antigen (HBsAg) are excluded. Patients with positive hepatitis B core antibody (anti-HBc) and negative HBsAg require hepatitis B polymerase chain reaction (PCR) evaluation before enrollment. Patients who are HBV DNA PCR positive will be excluded. Patients 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 (see the section on "General guidance for hepatic monitoring")
* Hepatitis C virus (HCV): positive hepatitis C antibody. If positive hepatitis C antibody result, patient will need to have a negative result for hepatitis C ribonucleic acid (RNA) before enrollment. Patients who are hepatitis C RNA positive will be excluded.
Known Cytomegalovirus (CMV) infection.
Evidence of other clinically significant uncontrolled condition(s) including but not limited to, uncontrolled systemic bacterial, viral, fungal, or parasitic infection (except for fungal nail infection), or other clinically significant active disease process which in the opinion of the investigator and medical monitor may pose a risk for patient participation. Screening for chronic conditions is not required.
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.
Active second malignancy unless in remission and with life expectancy \> 2 years.
Patients requiring therapeutic anticoagulation with warfarin or another vitamin K antagonist.
Receipt of live virus vaccines within 28 days prior to the initiation of study treatment or need for live-virus vaccines at any time during study treatment

Subjects taking medications that are known strong CYP3A4 inducers or inhibitors and cannot come off the medication.
Subjects taking medications that are known moderate CYP3A inducers and cannot come off the medication.
You may not be if
Prior exposure to tazemetostat or other inhibitor(s) of EZH2
Any prior history of myeloid malignancies including MDS/AML or MPN
Any prior history of T-LBL, T-ALL, or B-ALL

Significant liver disease (\>Child Pugh Class A)
Patients with CNS involvement
Prolongation of the QT interval corrected for heart rate (QTcF) \> 480 msec. QTcF is calculated using Fridericia's Formula (QTcF): QTcF = QT/(RR0.33).
* Correction of suspected drug induced QTcF prolongation can be attempted at the investigator's discretion and only if clinically safe to do so with either discontinuation of the offending drug or switch to another drug not known to be associated with QTcF prolongation.
