SJCAR19 and Combination Chemotherapy in Treating Younger Patients with CD19 Positive Relapsed or Refractory Acute Lymphoblastic Leukemia
This phase I/II trial studies the side effects and best dose of autologous anti-CD19 chimeric antigen receptor T-cells SJCAR19 (SJCAR19) and to see how well it works when given together with combination chemotherapy in treating younger patients with CD19 positive acute lymphoblastic leukemia that has come back (relapsed) or does not respond to treatment (refractory). SJCAR19 is an experimental therapy that takes peripheral (circulating) blood cells, and engineers them to make them more effectively kill cancer cells. SJCAR19 is created in the lab by genetically modifying T cells in such a way that allows the T cells to recognize cancer cells and attack them like an antibody would. Drugs used in chemotherapy, such as fludarabine phosphate and cyclophosphamide work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving SJCAR19 with combination chemotherapy may work better in treating younger patients with acute lymphoblastic leukemia.
