Combining Tazemetostat with CAR T Cell Therapy for B-cell Lymphomas

A Feasibility Trial of Tazemetostat Plus CAR T Cell Therapy in B-cell Lymphomas

Phase 1 Interventional Weill Medical College of Cornell University · NCT05934838

This study is testing if taking a new pill called tazemetostat before and after CAR T cell therapy can help people with certain types of B-cell lymphomas feel better and improve their treatment outcomes.

What this trial studies

This clinical trial evaluates the feasibility and safety of administering tazemetostat followed by CAR T cell therapy in patients with previously treated diffuse large B-cell lymphoma, follicular lymphoma, and mantle cell lymphoma. Participants will take tazemetostat orally for a period before and after receiving CAR T cell infusion, with the aim of enhancing the effectiveness of the CAR T cells in targeting lymphoma cells. The study will monitor participants for up to five years to assess outcomes and safety.

Who should consider this trial

Good fit: Ideal candidates include individuals with confirmed diagnoses of DLBCL, FL, or MCL who have received at least one prior therapy and are eligible for CAR T cell treatment.

Not a fit: Patients with active viral infections, other active cancers, or those unable to take oral medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve treatment outcomes for patients with B-cell lymphomas.

How similar studies have performed: While the combination of tazemetostat and CAR T cell therapy is a novel approach, similar studies have shown promise in enhancing CAR T cell effectiveness in hematological malignancies.
