Filter by:To search for a genetic marker of B-cell leukemias and lymphomas in children of Kazakh nationality, a single nucleotide polymorphism (SNP) analysis of DNA obtained from the peripheral blood of patients with B-cell leukemias and lymphomas in children of Kazakh nationality and normal control will be performed.
This is a single center, single arm, open-label, phase I study to evaluate the safety and efficacy of CD19/CD20 Dual-CAR-T cells in patients with refractory and relapsed B-cell leukemia.
Treatment of patients with B cell lymphoma or leukemia with two doses of CD19-targeting chimeric antigen receptor (CAR) T cells to evaluate for safety and efficacy.
Chimeric antigen receptor (CAR) T cells targeting CD19 will be evaluated for safety and efficacy in patients with B cell lymphoma or leukemia. The CAR consists of a CD19 targeting antibody scFv with three intracellular signaling domains derived from CD3 zeta, CD28 and 4-1BB. Autologous T cells will be gene engineered with the CAR gene using a retrovirus vector. Prior to T cell infusion, the patients will be subjected to preconditioning treatment. After T cell infusion, the patients will be evaluated for 24 months for adverse reactions, persistence of CAR T cells and efficacy.
This is a study for children who have been previously treated for Leukemia/Lymphoma. In particular, it is a study for people who have a type of Leukemia/Lymphoma that involves B cells (a type of white cell), which contain the cancer. This is a new approach for treatment of Leukemia/Lymphoma that involves B cells (tumor cells). This study will take the subject's white blood cells (T cells) and modify them in order to target the cancer. The subject's T cells will be modified in one or two different ways that will allow the cells to identify and kill the tumor cells (B cells). Both ways of modifying the cells tells the T cells to go to the B cells (tumor cells) and turn "on" and potentially kill the B cells (tumor cells). The modification is a genetic change to the T cells, or gene transfer, in order to allow the modified T cells to recognize your tumor cells but not other normal cells in the subject's body. These modified cells are called chimeric antigen receptor 19 (CART19) T-cells.
The purpose of this study is to assess the safety and tolerability of BMS-936564 (MDX-1338) in relapsed Acute myelogenous leukemia (AML) and other selected B-cell cancers and to determine the maximum tolerated dose (MTD) of the drug alone in relapsed/refractory AML
Background: - Allogeneic hematopoietic stem cell transplantation (alloHSCT) is a procedure that transplants bone marrow cells (stem cells) from a matching donor into a recipient in order to allow the donor stem cells to produce cells that will attack the recipient s cancer cells. AlloHSCT is performed when chemotherapy, immunotherapy, or radiation therapy do not adequately control cancer growth. However, cancers that are not controlled by alloHSCT frequently become resistant to other standard treatment options. - The outcomes of alloHSCT might be improved if certain kinds of white blood cells (T cells) could be manipulated so that they generate a more potent effect against the cancer cells. This effect can be augmented by genetically engineering donor T cells to specifically recognize cancerous cells in order to attack them. For this purpose, researchers are studying a specific kind of genetically engineered T cell known as the anti-CD19-CAR-transduced T cell. More research is needed to determine if this T cell will be an effective treatment for certain kinds of B cell cancer (such as non-Hodgkin s lymphoma and chronic lymphocytic leukemia) that has not been controlled with alloHSCT. Objectives: - To assess the safety and effectiveness of administering allogeneic anti-CD19-CAR-transduced T cells to patients with B-cell cancer that has not responded to alloHSCT. Eligibility: - Individuals between 18 and 75 years of age who have received allogeneic hematopoietic stem cell transplantation for a B cell cancer, but whose cancer has either not responded to or recurred after the transplant. - Recipients must have the same stem cell donor from their previous procedure. Design: - Before the start of the study, all participants will be screened with a medical history and blood tests. Recipients will have tumor imaging scans, additional blood tests, and other tests as directed by the study doctors. - Donor participants will undergo apheresis to provide white blood cells for researchers to use in the treatment. - Recipients will have dose escalation to determine the most effective yet safe dose of anti-CD19 T cells. There will be six dose levels of anti-CD19 T cells. The first patients enrolled will have the smallest dose, and the dose will be increased when a level has been determined to be safe. . - Recipients will be hospitalized for at least 9 days after receiving the cell infusion, and will need to come to clinic for follow-up visits 2, 4, 8, and 12 weeks after the infusion. - Additional scans and frequent blood tests will be required for the first 3 months after the infusion, followed by less frequent visits over time. - Recipients will be followed for a maximum of 15 years after receiving the infusion.
The purpose of this study is to establish the safety and optimal dose of orally administered PCI-32765 in patients with recurrent B cell lymphoma.
The main aim of this study is to test the safety of acadesine in patients with B-CLL and see what effects it has on patients and their leukaemia. The study also aims to examine the way acadesine is processed by the body. The study will look at the effects of acadesine in the body and the concentration of the drug and its main by-product (ZMP) in the blood to determine the dose and the frequency of dosing that is likely to be the most effective.
Studies have shown that both high-dose Methylprednisolone and Rituximab used as single agents are effective in relapsed and refractory B-CLL. Methylprednisolone acts independently of p53 apoptosis pathway. The combination of both drugs may improve response and outcome in previously treated high-risk B-CLL patients. Study Objectives Primary: To determine the clinical benefit of high-dose Methylprednisolone and Rituximab in previously treated high-risk B-CLL patients in terms of clinical and flowcytometric response rate. Secondary: To determine progression free and overall survival. To characterize the safety profile of high-dose Methylprednisolone and Rituximab.
