This clinical trial is focused on studying a type of blood cancer called acute lymphoblastic leukemia (ALL), which can be difficult to treat when it comes back or does not respond to standard treatments. The study is specifically for children, adolescents, and young adults who have this condition. The trial will explore the use of two different cell therapies: CART45RA-NKG2D cells and CART 19/22 T cells. These are special treatments that involve using modified cells to help the body fight the cancer.
The purpose of the study is to assess the safety and feasibility of these treatments. Participants will receive the treatment through an intravenous infusion, which means the medicine is given directly into a vein. The study will be conducted in different groups, with each group receiving one of the two treatments. The trial will monitor how well the treatments work and how long the modified cells stay in the body. It will also look at the body’s response to the treatment, including any changes in the blood and other samples.
The trial aims to provide new insights into treating acute lymphoblastic leukemia in young patients who have limited options. By participating in this study, researchers hope to find more effective ways to manage this challenging condition and improve outcomes for those affected. The study is expected to continue until the end of 2028, with recruitment starting in mid-2024.
