Engineered t cells take on tough leukemia and lymphoma

NCT ID NCT00466531

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-phase trial tests a two-part treatment for people with relapsed or chemotherapy-resistant B-cell leukemia or lymphoma. First, patients receive a chemotherapy drug (cyclophosphamide) to help prepare the body. Then, they get an infusion of their own T cells that have been genetically modified in the lab to recognize and attack cancer cells carrying the CD19 protein. The study aims to check safety and how well this approach works in up to 50 participants.

What this could mean

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

Active substance
genetically modified T cells (CAR T-cells) and cyclophosphamide chemotherapy
What this could lead to
If successful, this could point toward a new treatment option for patients with hard-to-treat B-cell cancers that have come back after standard therapy.
What could go wrong
This is an early-phase trial with only 50 participants, so results may not apply to everyone. There are risks from the chemotherapy and the modified T cells, including severe immune reactions.
