Active clinical trials for "Leukemia, B-Cell"

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.

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.

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.

The purpose of this study is to determine if a subcutaneous (SC) dosing schedule of veltuzumab can be established in NHL or CLL patients and to confirm the safety and efficacy of veltuzumab that was previously established when administered intravenously.

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.

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.

This study is for patients that have chronic lymphocytic leukemia (CLL). This research study aims to determine the safety and dosage of special cells that may make the patients own immune system fight the cancer. To do this, we will put a special gene into cancer cells that have been taken from the patients body. This will be done in the laboratory. This gene will make the cells produce interleukin 2 (IL-2), which is a natural substance that may help the immune system kill cancer cells. Additionally, we will stimulate the cancer cells with another natural protein called CD40 ligand (CD40L), which experiments in animal and human cells in vitro demonstrated can help IL-2 perform better. Some of these cells will then be put back into the patient's body. Studies of cancers in animals and in cancer cells that are grown in laboratories suggest that combining substances like IL-2 and CD40L helps the body kill cancer cells. An experimental treatment similar to this has already been used in children and similar experimental treatments are being used in adults with other cancers.

Phase II trial to study the effectiveness of combining rituximab and rasburicase with combination chemotherapy in treating young patients who have newly diagnosed advanced B-cell leukemia or lymphoma. Monoclonal antibodies such as rituximab can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Drugs used in chemotherapy work in different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug with rituximab may kill more cancer cells. Chemoprotective drugs such as rasburicase may protect kidney cells from the side effects of chemotherapy.

In this study participants with relapsed/refractory leukemia will be given MK-0457 in sequential cohorts and with varying treatment duration to determine the maximum tolerated dose (MTD) for MK-0457.

This study combines the immune checkpoint inhibitor pembrolizumab with the BITE antibody blinatumomab for the treatment of relapsed/refractory pre-B cell ALL. Pembrolizumab at the proposed dosing schedule has been very well tolerated in adult studies, including elderly and unfit patients, as well as in pediatric patients. Both blinatumomab and pembrolizumab are FDA-approved for use in children as well as adults. Phase I/II trials in adult patients have demonstrated safety and activity of pembrolizumab in combination with multiple agents. In this trial, the combination of pembrolizumab and blinatumomab will be investigated for toxicity as well as possible synergy in the treatment of relapsed/refractory pre-B cell ALL. This is a single institution investigator-initiated pilot study designed to test the safety and feasibility of combining pembrolizumab and blinatumomab immunotherapies in children, adolescents, and young adults with CD19 positive hematologic malignancies. The investigator will define the toxicity profile of the combination in two safety strata based on whether or not a patient has had a prior allogeneic hematopoietic stem cell transplant (HSCT), as they hypothesize that the immune toxicities may differ between strata. In addition, the overall response rate (CR/CRh) to this therapy will be estimated. Additional biologic correlates will be conducted to delineate the effect of the combination therapy on the patient's leukemia/lymphoma and T-cell populations and how this may influence response to therapy.
