Anti-CD22 Chimeric Receptor T Cells in Pediatric and Young Adults With Recurrent or Refractory CD22-expressing B Cell Malignancies

Background: - One type of cancer therapy takes blood cells from a person, changes them in a lab, then gives the cells back to the person. In this study, researchers are using an anti-CD22 gene, a virus, and an immune receptor to change the cells. Objective: - To see if giving anti-CD22 Chimeric Antigen Receptor (CAR) cells to young people with certain cancers is safe and effective. Eligibility: - People ages 1-39 with a leukemia or lymphoma that has not been cured by standard therapy. Design: - Participants will be screened to ensure their cancer cells express the CD22 protein. They will also have medical history, physical exam, blood and urine tests, heart tests, scans, and x-rays. They may give spinal fluid or have bone marrow tests. - Participants may have eye and neurologic exams. - Participants will get a central venous catheter or a catheter in a large vein. - Participants will have white blood cells removed. Blood is removed through a needle in an arm. White blood cells are removed. The rest of the blood is returned by needle in the other arm. - The cells will be changed in a laboratory. - Participants will get two IV chemotherapy drugs over 4 days. Some will stay in the hospital for this. - All participants will be in the hospital to get anti-CD22 CAR cells through IV. They will stay until any bad side effects are gone. - Participants will have many blood tests. They may repeat some screening exams. - Participants will have monthly visits for 2-3 months, then every 3-6 months. They may repeat some screening exams. - Participants will have follow-up for 15 years.
