NCT05934838

Brief Summary

This is a clinical trial to evaluate the feasibility and safety of giving tazemetostat followed by standard of care CAR T cell infusion in previously treated diffuse large b-cell lymphoma (DLBCL), follicular lymphoma (FL), and mantle cell lymphoma (MCL). The investigators hypothesis is that this combination has the potential to significantly improve the ability of CART cells to recognize and kill lymphoma cells without a significant impact on safety. Participants will receive the tazemetostat pills before and after receiving their CAR T cell therapy, for up to 12 months after CAR T cell administration. Patients will be followed for up to 5 years.

Outcome Measures

Primary Outcomes (1)

  • Number of participants who experience adverse events classified per CTCAEv5

    Adverse reactions will be graded as per National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.

    From start of treatment until 30 days after the last dose of tazemetostat, for a maximum of approximately 13 months

Secondary Outcomes (5)

  • Number of patients who experience cytokine release syndrome (CRS) by ASTCT Consensus Grading system during therapy

    From start of treatment until Day 21 days following CAR T cell infusion

  • Number of patients who experience immune effector cell neurotoxicity syndrome (ICANS) by ASTCT Consensus Grading system during therapy

    From start of treatment until Day 21 days following CAR T cell infusion

  • Overall response rate (ORR) reported as per Lugano response criteria

    From start of treatment until disease progression or death, for a maximum of approximately 6 years

  • Mean Progression-Free Survival (PFS)

    From start of treatment until disease progression or death, for a maximum of approximately 6 years

  • Mean Overall Survival (OS)

    From start of treatment until death, for a maximum of approximately 6 years

Study Arms (1)

Tazemetostat and CAR T-Cell Therapy

EXPERIMENTAL

Tazemetostat is being administered prior to, and following, standard of care CAR T cell therapy. The use of tazemetostat in this way is investigational.

Drug: Tazemetostat Pill

Interventions

Participants will take 800 mg of tazemetostat twice a day starting 7 days before apheresis and continue to take tazemetostat until lymphodepletion, which is chemotherapy given prior to receiving the CAR T cells. Participants will stop taking tazemetostat after lymphodepletion until after CAR T cell infusion. Once lymphocyte counts increase, tazemetostat will be resumed and tazemetostat will be taken for 6 - 12 months, depending on participant response.
