Boosting CAR t cells: could a pill make lymphoma therapy more effective?
NCT ID NCT05934838
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This trial explores whether adding the drug tazemetostat (Tazverik) to standard CAR T cell therapy can help the immune cells better recognize and destroy lymphoma cells. It enrolls people with diffuse large B-cell lymphoma, follicular lymphoma, or mantle cell lymphoma who have already tried at least one prior treatment. Participants take tazemetostat pills before and after receiving their CAR T cells, continuing for up to a year, and are monitored for side effects and response for up to five years.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tazemetostat (Tazverik) plus CAR T cells
- What this could lead to
- If successful, this combination could make CAR T therapy more effective at killing lymphoma cells, potentially improving long-term control of the disease.
- What could go wrong
- This is a small, early-phase feasibility study, so results may not apply broadly. Adding tazemetostat could increase side effects like cytokine release syndrome or immune-related neurotoxicity.
