TazemetostatTazemetostatParticipants with relapsed or refractory follicular lymphoma with EZH2 gene mutation will receive Tazemetostat 800 milligram (mg), tablet, orally, twice daily or as per physicians discretion in routine clinical practice.

Primary Outcome Measures
NameTimeMethod
Number of Participants With Serious ADRsUp to Week 52

Serious ADRs are defined as any untoward medical occurrence or effect that at any dose resulted in death or life-threatening conditions or required hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, congenital anomaly or birth defect or medically important condition.

Number of Participants With Adverse Drug Reactions (ADRs)Up to Week 52

An ADR is defined as harmful and unintended responses to the normal administration/use of drugs, in which a causal relationship with the drug in question cannot be ruled out. Adverse events (AEs) with unknown causality to the drug among those voluntarily reported will be also considered ADRs.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants with Overall ResponseUp to Week 52

Overall response rate is defined as a percentage of participants who achieved a best response including complete response (CR) or partial response (PR) based on Revised Response Criteria for Malignant Lymphoma (Cheson, 2007). CR: defined as disappearance of all target lesions, non-target lesions, no new lesions, and normalization of tumor marker level. PR: defined as at least a 30 percent (%) decrease in the sum of diameters of target lesions, no progression in non-target lesion, and no new lesions.

Number of Participants With ADRs Based on Participant Background FactorsUp to Week 52

Number of participants with ADRs such as myelosuppression and infection based on participants background factors will be reported. Participant background factors will be sex, age, height, weight, clinical stage (Ann Arbor classification), the presence or absence of B symptoms, Eastern Cooperative Oncology Group Performance Status (ECOG-PS), complications, past history and history of drug allergy.
