Registration Number
NCT05934838
Lead Sponsor
Weill Medical College of Cornell University
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.

Detailed Description

This is a single arm, open label, clinical trial to evaluate the feasibility and safety of oral tazemetostat followed by standard of care CAR T cell infusion in previously treated DLBCL, FL, and 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.

Tazemetostat 800 mg will be given twice daily by mouth for at least 1 week prior to apheresis, during the period between apheresis and CAR T infusion, and following lymphodepletion chemotherapy until Day 7 post-CAR T therapy. Once patients' platelets and neutrophil counts recover, tazemetostat will be resumed. Tazemetostat treatment will continue for up to 6 months in patients with complete responses and up to 12 months in patients with partial responses.

A 3+3 trial design will be implemented for the first six patients enrolled. The regimen will be considered feasible if at least 12 out of 15 subjects are able to receive at least 2 weeks of tazemetostat, generate the CAR T cell product and receive CAR T cell therapy.

Tazemetostat and CAR T-Cell TherapyTazemetostat PillTazemetostat is being administered prior to, and following, standard of care CAR T cell therapy. The use of tazemetostat in this way is investigational.
Primary Outcome Measures
NameTimeMethod
Number of participants who experience adverse events classified per CTCAEv5From start of treatment until 30 days after the last dose of tazemetostat, for a maximum of approximately 13 months

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

Secondary Outcome Measures
NameTimeMethod
Overall response rate (ORR) reported as per Lugano response criteriaFrom start of treatment until disease progression or death, for a maximum of approximately 6 years

Overall response rate will be reported as the number of participants who achieve a complete or partial response per the Lugano response criteria

Mean Progression-Free Survival (PFS)From start of treatment until disease progression or death, for a maximum of approximately 6 years

PFS is defined as the duration of time from start of treatment to time of documentation of progression or death from any cause.

Number of patients who experience cytokine release syndrome (CRS) by ASTCT Consensus Grading system during therapyFrom start of treatment until Day 21 days following CAR T cell infusion

Patients will undergo screening for CRS per American Society for Transplantation and Cellular Therapy (ASTCT) guidelines

Number of patients who experience immune effector cell neurotoxicity syndrome (ICANS) by ASTCT Consensus Grading system during therapyFrom start of treatment until Day 21 days following CAR T cell infusion

Patients will undergo screening for ICANS per American Society for Transplantation and Cellular Therapy (ASTCT) guidelines

Mean Overall Survival (OS)From start of treatment until death, for a maximum of approximately 6 years

OS is defined as the duration of time from start of treatment to death from any cause.
