2. Have histologically confirmed Follicular Lymphoma (FL), all grades. Subjects may
have relapsed/refractory disease following at least 2 standard prior systemic
treatment regimens where at least 1 anti-CD20-based regimen was used. Subjects

16 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Prior exposure to tazemetostat or other inhibitor(s) of EZH2.

2. Subjects with leptomeningeal metastases or brain metastases or history of previously

leukemia (T-ALL).

5. Subjects taking medications that are known strong CYP3A inhibitors and strong or
moderate CYP3A inducers (including St. Johns Wort) 6. Subjects unwilling to remove
Seville oranges, grapefruit juice and grapefruit from their diet.

6. Any unstable or unresolved prior treatment-related (i.e. chemotherapy, immunotherapy,
radiotherapy) toxicities at time of enrollment.

7. Major surgery within 4 weeks before the first dose of study drug. .

8. Inability to take oral medication, or malabsorption syndrome or any other uncontrolled
gastrointestinal condition (e.g., nausea, diarrhea, or vomiting) that might impair the
bioavailability of tazemetostat.

9. Significant cardiovascular impairment: history of congestive heart failure greater
than New York Heart Association (NYHA) Class II, uncontrolled arterial hypertension,
unstable angina, myocardial infarction, or stroke within 6 months of the first dose of
study drug; or cardiac ventricular arrhythmia.

10. Venous thrombosis or pulmonary embolism within the last 3 months before starting
tazemetostat.

11. Active infection requiring systemic therapy.

12. Immunocompromised patients, including patients known to be infected with human
immunodeficiency virus (HIV).

13. Any other major illness that, in the investigator's judgment, will substantially
increase the risk associated with the subject's participation in this study.

14. Females who are pregnant or breastfeeding.

15. Phase 2 only: Subjects with noncutaneous malignancies other than B-cell lymphomas.
Exception: Subjects with another malignancy who have been disease-free for 5 years, or
