Filter by:Acute leukemia, including acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL), is the subtype of leukemia with the highest mortality, and leukemia relapse caused by the protective bone marrow microenvironment is the main cause of treatment failure. The chemokine receptor CXCR4 plays a crucial role in the homing and settling of leukemia cells into the bone marrow. Preclinical study of the investigators demonstrates that CXCR4 blockade can mobilize leukemia cells from their protective bone marrow microenvironment to periphery, thereby significantly enhancing the killing effect of allogeneic lymphocytes against leukemia cells. This study aims to preliminarily evaluate the efficacy and safety of donor lymphocyte infusion (DLI) plus CXCR4 antagonist plerixafor in the treatment of relapsed acute leukemia patients after allogeneic hematopoietic stem cell transplantation (allo-HSCT) through a prospective single arm study. The results may preliminarily confirm the effectiveness and safety of DLI combined with plerixafor in the treatment of recurrent acute leukemia patients after allo-HSCT, providing a reference basis for further research.
This is a phase 1, open-label study to assess the efficacy, safety and pharmacokinetics of ThisCART19A (Allogeneic Anti CD19 CAR-T) bridging to HSCT in patients with refractory or relapsed B cell acute lymphoblastic leukemia (r/r B-ALL).
The patients with relapsed B cell acute lymphoblastic leukemia (ALL) after hematopoietic stem cell transplant (HSCT) have a poor prognosis, especially for these relapsed in a short time after transplantation. Nowadays there is no effective way to salvage patients in such conditions. T cells derived from healthy matched sibling or unrelated donors have not been restrained by tumor micro-environment and retain anti-leukemia ability, which makes it serve well for patients with relapsed B-ALL. So we launched a multi-center clinical trial to proved the safety and efficacy of anti-CD19 CAR-T cells for relapsed B cell ALL.
Autologous, unselected CD3+ lymphocytes collected from apheresis, transfected with a lentiviral vector containing a 2nd generation chimeric antigen receptor (CAR) consisting of a scFv recognizing CD19 and dual co-stimulatory intracellular signaling domains (4-1BB and CD3ζ).
This study is for patients who have lymphoma or leukemia that has come back or has not gone away after treatment. Because there is no standard treatment for this cancer, patients are being asked to volunteer for a gene transfer research study using special immune cells. The body has different ways of fighting infection and disease. No single way seems perfect for fighting cancers. This research study combines two different ways of fighting disease, antibodies and immune cells. Antibodies are types of proteins that protect the body from bacteria and other diseases. Immune cells, also called lymphocytes, are special infection-fighting blood cells that can kill other cells including tumor cells. Both antibodies and lymphocytes have been used to treat patients with cancer. They have shown promise, but have not been strong enough to cure most patients. The antibody used in this study is called anti-CD19. This antibody sticks to lymphoma cells because of a substance on the outside of the cells called CD19. CD19 antibodies have been used to treat people with lymphoma and leukemia. For this study, the anti-CD19 antibody has been changed so that instead of floating free in the blood it is now joined to the NKT cells, a special type of lymphocytes that can kill tumor cells but not very effectively on their own. When an antibody is joined to a T cell in this way it is called a chimeric receptor. Investigators have also found that NKT cells work better if proteins are added that stimulate lymphocytes, such as one called CD28. Adding the CD28 makes the cells last for a longer time in the body but maybe not long enough for them to be able to kill the lymphoma cells. It is believed that by adding an extra stimulating protein, called IL-15, the cells will have an even better chance of killing the lymphoma cells. In this study the investigators are going to see if this is true by putting the anti-CD19 chimeric receptor with CD28 and the IL-15 into NKT cells grown from a healthy individual. These cells are called ANCHOR cells. These cells will be infused into patients that have lymphomas or leukemias that have CD19 on their surface. The ANCHOR cells are investigational products not approved by the Food and Drug Administration. The purpose of this study is to find the biggest dose of ANCHOR cells that is safe, to see how long the ANCHOR cells last, to learn what their side effects are and to see whether this therapy might help people with lymphoma or leukemia.
This study will evaluate the safety of infusing an anti-MiHA T cell line in patients suffering from an hematologic malignancy that has relapsed following hematopoietic stem cell transplantation from a matched donor.
