What this Trial Is About

Researchers are evaluating the feasibility and safety of combining tazemetostat, an oral medication, with standard CAR T cell therapy in patients with previously treated diffuse large B-cell lymphoma, follicular lymphoma, and mantle cell lymphoma. The study aims to see if this combination can help CAR T cells better identify and kill lymphoma cells without causing significant safety issues. This is a phase 1, single-arm, open-label trial exploring this new approach. Participants will take 800 mg of tazemetostat pills twice daily starting at least one week before apheresis (a procedure to collect immune cells), continuing until lymphodepleting chemotherapy begins. They will pause tazemetostat during chemotherapy and CAR T cell infusion, then resume once blood counts recover. Depending on the response, tazemetostat treatment may continue for up to 6 months in those with complete responses or up to 12 months in those with partial responses. This treatment plan is investigational and designed to assess feasibility. During the study, participants will be monitored for side effects and treatment responses. Safety will be assessed by recording adverse events from the start of treatment until about 13 months afterward, including specific monitoring for cytokine release syndrome and neurotoxicity up to 21 days post-CAR T infusion. Researchers will also evaluate overall response rates, progression-free survival, and overall survival for up to 6 years. Participants will be followed for up to 5 years in total to understand long-term outcomes.

Your Study Journey

Screening

Duration - 2 to 4 weeks

Participants are screened for eligibility to participate in the trial.

1 visit (in-person)

Run-in Period

Duration - At least 1 week

Participants take oral tazemetostat twice daily starting 7 days before apheresis to prepare for CAR T cell therapy.

1 visit for apheresis

Treatment

Duration - Up to 12 months depending on response

Participants receive lymphodepletion chemotherapy followed by CAR T cell infusion. Tazemetostat is paused during lymphodepletion and resumed after CAR T cell therapy once blood counts recover, continuing for 6 to 12 months depending on response.

Multiple visits including lymphodepletion, CAR T infusion, and follow-up visits during treatment

Follow-up

Duration - Up to 6 years

Participants are monitored for safety and treatment efficacy, including adverse events, cytokine release syndrome, neurotoxicity, and disease progression for up to 6 years.

Regular visits scheduled for safety and efficacy assessments
