Engineered immune cells take on stubborn leukemia
NCT ID NCT03919240
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a treatment using a patient's own immune cells, modified to find and attack cancer cells that carry a marker called CD19. It is for people with B-cell acute lymphoblastic leukemia that has not responded to standard treatments or has come back. The goal is to see if this therapy can put the cancer into remission and how long that remission lasts.
