研究概览
简要总结
The goal of this clinical research study is to learn if researchers can successfully and safely give HSCT patients an infusion of white blood cells (called T-cells) that have been genetically changed. The process of changing the DNA (the genetic material in cells) of these T-cells is called "gene transfer." Researchers want to learn if these genetically-changed T-cells are effective in attacking cancer cells in patients with advanced B-cell lymphoma or leukemia, after they have received standard allogeneic HSCT. Researchers want to find out the highest dose of these special T-cells that can be given safely to leukemia and lymphoma patients. Researchers also want to learn how long the changed T-cells stay in your body, and if adding them to standard transplant can improve how you respond to treatment.
详细描述
Gene Transfer:
Gene transfer involves drawing blood from a transplant donor, and then separating out the T-cells using a machine. Researchers then perform a gene transfer to change the T-cells' DNA, and then inject the changed T-cells into the body of the patient receiving the transplant. This process is called a modified donor lymphocyte infusion (DLI).
Study Groups:
If you are found to be eligible to take part in this study, you will be assigned to 1 of 4 study arms, based on your age, treatment schedule, and disease status:
- Participants in Arm 1 will receive the T-cells by vein about 6-12 weeks after the stem cell transplant. (Adults participants only)
- Participants in Arm 2 will receive the T-cells by vein if, at any point, the disease comes back after stem cell transplant. Your doctor may decide that you need to receive chemotherapy before you are given the T-cells, in order to clear out the T-cells that are in your body already. This may help the infused T-cells work better. If more chemotherapy is needed, you will sign another informed consent document, which will the chemotherapy and its risks in detail. (Pediatric and adult participants eligible)
- Participants in Arm 3 will receive the T-cells by vein about 6-12 weeks after the stem cell transplant. (Pediatric participants [ages 1-17] only)
- Participants in Arm 4 will be given the T-cells as a scheduled infusion or if the disease comes back. This group is also scheduled to receive a stem cell transplant from a mismatched family member donor. (Pediatric and adult participants eligible)

Patients in first remission are eligible if they are considered high risk, defined as any of the following detected at any time:1) Acute Lymphoblastic Leukemia (ALL) with translocations 9;22 or 4;11, hypodiploidy, complex karyotype, secondary leukemia developing after cytotoxic drug exposure,and/or evidence of minimal residual disease, 2) acute biphenotypic leukemia, or 3) double hit nonHodgkin's lymphoma. Non-Hodgkin's Lymphoma (NHL) in second or third complete remission, or relapse (including relapse post autologous hematopoietic stem cell transplant). Double hit lymphomas in first remission or more advanced disease. Small Lymphocytic Lymphoma (SLL), or Chronic Lymphocytic Leukemia (CLL) with progressive disease following standard therapy.
- •Age 1 to 65 years old.
