Could adjusting chemo doses boost CAR T-Cell success against tough lymphoma?

NCT ID NCT05052528

First seen Jul 17, 2026 · Last updated Jul 17, 2026

Summary

This phase I trial is testing different doses of chemotherapy given before a patient's own genetically modified immune cells (CAR T-cells) are infused to treat diffuse large B-cell lymphoma that has returned or not responded to prior treatment. The goal is to find the safest and most effective chemotherapy dose to prepare the body for the CAR T-cells, which are designed to recognize and kill cancer cells. The study involves adults whose commercial CAR T-cell therapy is not available, and it closely monitors side effects and treatment response.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
chemotherapy (fludarabine and cyclophosphamide with or without rituximab) followed by CD19 chimeric antigen receptor (CAR) T-cell therapy
What this could lead to
If successful, this could help determine the best chemotherapy dose to prepare the body for CAR T-cell therapy, potentially improving outcomes for people with hard-to-treat lymphoma.
What could go wrong
This is an early-phase trial with a small number of participants, so results may not apply broadly. There are risks of serious side effects from both the chemotherapy and the CAR T-cells, including infusion reactions and organ damage.
