CD19x22 CAR T-cell Therapy for Pediatric B-ALL

This study is testing a new type of cell therapy called CD19x22 CAR T for children and young adults (ages 3 months to 30 years) with B-cell Acute Lymphoblastic Leukemia (B-ALL) that has come back or hasn't responded to other treatments. This therapy uses your own immune cells, called T-cells, which are specially modified to recognize and fight cancer cells. The main goal is to see how safe the CD19x22 CAR T therapy is and if it causes any serious side effects in the first 28 days after treatment. You might be able to join if your B-ALL has relapsed two or more times, relapsed after a bone marrow transplant, or relapsed after a different CAR T-cell therapy. The study plans to enroll up to 53 patients, but the current recruitment status is unclear.

Study design
This is an open-label Phase I study with two groups of patients, enrolling up to 53 participants. It will determine the safety and tolerability of the CD19x22 CAR T therapy.
What's involved
You would receive chemotherapy to prepare your body, followed by the CD19x22 CAR T cell infusion. You will be monitored for side effects for up to 28 days after the infusion.
Compensation
Not stated in the trial record.
Follow-up
Safety will be measured up to 28 days after the infusion date.
