Filter by:Patients eligible for this study have a type of blood cancer called T-cell leukemia or lymphoma (lymph gland cancer). The body has different ways of fighting infection and disease. No one way seems perfect for fighting cancers. This research combines two different ways of fighting disease, antibodies and T cells. Antibodies are proteins that protect the body from bacterial and other diseases. T cells, or T lymphocytes, are special infection-fighting blood cells that can kill other cells including tumor cells. Both antibodies and T cells have shown promise treating patients with cancers, but have not been strong enough to cure most patients. T lymphocytes can kill tumor cells but there normally are not enough of them. Some researchers have taken T cells from a person's blood, grown more in the lab then given them back to the person. In some patients who've had recent bone marrow or stem cell transplant, the number of T cells in their blood may not be enough to grow in the lab. In this case, T cells may be collected from their previous transplant donor, who has a similar tissue type. The antibody used in this study, called anti-CD5, first came from mice that have developed immunity to human leukemia. This antibody sticks to T-cell leukemia or lymphoma cells because of a substance on the outside of these cells called CD5. CD5 antibodies have been used to treat people with T-cell leukemia and lymphoma. For this study, anti-CD5 has been changed so that instead of floating free in the blood it is now joined to the T cells. When an antibody is joined to a T cell in this way it is called a chimeric receptor. In the lab, investigators have also found that T cells work better if stimulating proteins, such as one called CD28, are also added. Adding the CD28 makes the cells grow better and last longer in the body, giving them a better chance of killing the leukemia or lymphoma cells. In this study investigators will attach the CD5 chimeric receptor with CD28 added to it to the patient's T cells or the previous bone marrow transplant donor's T cells. The investigators will then test how long the cells last. The decision to use the bone marrow transplant donor's T cells instead of the patient's will be based on 1) whether there is an available and willing donor and 2) the likelihood of the patient's T cells being able to grow in the lab. These CD5 chimeric receptor T cells with CD28 are investigational products not approved by the FDA.
This study will evaluates the safety and efficacy of Chimeric antigen receptor T cells (CAR-T) in treating central nervous system B-cell acute lymphocytic leukemia.
Study of the intermediate metabolism in children diagnosed with ALL compared to healthy matched controls.
CART-19 cells has emerged as a powerful targeted immunotherapy, showing striking responses in highly refractory CD19+ acute lymphoblastic leukemia (ALL). This study aims to assess the safety and toxicity of CART-19 cells to patients who are refractory or at highest risk of relapse as defined by MRD+ status.
The study will investigate, in children with acute lymphoblastic leukemia during maintenance treatment, if addition of allopurinol to conventional oral 6-mercaptopurine and methotrexate therapy, affects erythrocyte concentrations of 6-thioguanine and 6 methylmercaptopurine. The effect on hematological and liver toxicity parameters in blood will also be investigated as well as clinical toxicity.
The trial is a single arm, single-center, non-randomized phase I clinical trial which is designed to evaluate the safety and efficacy of C-CAR011 in treatment of adult subjects with relapsed/refractory CD19+ B cells acute lymphoblastic leukemia(r/r CD19+B-ALL)
The body has different ways of fighting infection and disease. No single way is effective at fighting cancer. This research study combines two different ways of fighting disease: antibodies and T cells. Antibodies are proteins that protect the body from disease caused by bacteria or toxic substances. Antibodies work by binding those bacteria or substances, which stops them from growing and causing bad effects. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells, including tumor cells or cells that are infected. Both antibodies and T cells have been used to treat patients with cancers. They both have shown promise, but neither alone has been sufficient to cure most patients. This study combines both T cells and antibodies to try to create a more effective treatment. This investigational treatment is called autologous T lymphocyte chimeric antigen receptor cells targeted against the CD19 antigen (ATLCAR.CD19) administration. In previous studies, it has been shown that a new gene can be put into T cells that will increase their ability to recognize and kill cancer cells. A gene is a unit of DNA. Genes make up the chemical structure carrying the genetic information that may determine human characteristics (i.e., eye color, height and sex). The new gene that is put in the T cells makes a piece of an antibody called anti-CD19. This antibody can flow through the blood and can find and stick to leukemia cells because these leukemia cells have a substance on their surface called CD19. Anti-CD19 antibodies have been used to treat people with leukemia but have not been strong enough to cure most patients. For this study, the anti-CD19 antibody has been changed so that instead of floating free in the blood a piece of it is now joined to the surface of the T cells. Only the part of the antibody that sticks to the leukemia cells is attached to the T cells instead of the entire antibody. When an antibody is joined to a T cell in this way it is called a chimeric receptor. These CD19 chimeric (combination) receptor-activated T cells kill some of the tumor, but they do not last very long in the body and so their chances of fighting the cancer are unknown. Preliminary results of giving ATLCAR.CD19 cells to leukemia patients have been encouraging; however, many subjects receiving this treatment have experienced unwanted side effects including neurotoxicity and/or cytokine release syndrome (also referred to as cytokine storm or an infusion reaction). Cytokines are small proteins that interreact as e signals to other cells and are the way cells talk to one another. During cytokine release syndrome, too many cytokines are released and too many cells in your body react to their release. Symptoms resulting from cytokine release syndrome vary from flu-like symptoms to more severe side effects such as cardiac arrest, multi-system organ failure or death. We predict that about 50% of patients on this study will experience mild to severe cytokine release syndrome. To help reduce cytokine release syndrome symptoms in future patients, a safety switch has been added to the ATLCAR.CD19 cells that can cause the cells to become dormant or "go to sleep". The safety switch is called inducible caspase 9 or iC9. The modified ATLCAR.CD19 cells with the safety switch are referred to as iC9-CAR19 cells. The purpose of this study is to determine whether receiving the iC9-CAR19 cells is safe and tolerable (there are not too many unwanted effects). Researchers has previously tested different doses of the iC9-CAR19. An effective dose that had the least number of unwanted side effects in patients was identified. It was planned to test this dose in more patients to learn more about its effect in the body. This type of research study is called a dose expansion study. It will allow the investigators to collect more information about the effect of this dose in treating of certain type of cancer.
This randomized phase III trial studies how well imatinib mesylate works in combination with two different chemotherapy regimens in treating patients with newly diagnosed Philadelphia chromosome positive acute lymphoblastic leukemia (ALL). Imatinib mesylate has been shown to improve outcomes in children and adolescents with Philadelphia chromosome positive (Ph+) ALL when given with strong chemotherapy, but the combination has many side effects. This trial is testing whether a different chemotherapy regimen may work as well as the stronger one but have fewer side effects when given with imatinib. The trial is also testing how well the combination of chemotherapy and imatinib works in another group of patients with a type of ALL that is similar to Ph+ ALL. This type of ALL is called "ABL-class fusion positive ALL", and because it is similar to Ph+ ALL, is thought it will respond well to the combination of agents used to treat Ph+ ALL.
Previous findings have shown that a biomarker comprised of the three microRNAs (miRs) miR-451, miR-151-5p and miR-1290 can independently predict precursor B-cell acute lymphoblastic leukemia (B- ALL) patients' risk for relapse when measured in cells from a bone marrow (BM) aspiration taken at diagnosis (Avigad et al., 2016: Genes, Chromosomes & Cancer 55:328-339). Curewize Health recognizes that the development of a minimally invasive blood test for frequent long-term monitoring can greatly benefit pediatric precursor B-ALL patients. Therefore, the current study will investigate the monitoring ability of miR-451, miR-151-5p and miR-1290 measured in blood samples. The study will be performed in two stages: Stage 1-Cross-Sectional Study: Blood samples will be collected from relapsed pediatric B-ALL patients and B-ALL patients in remission. Blood will be collected from each patient in three tubes, for serum, plasma and whole blood analysis, in order to interpret the best blood source for measuring miR-451, miR-151-5p and miR-1290. The level of the miRs in blood will be compared between relapsed B-ALL patients to B-ALL patients in remission. If the Stage 1 Cross-Sectional study is successful, the investigators will continue the clinical trials to the Stage 2 Prospective Monitoring study. Stage 2-Prospective Monitoring Study: Blood will be collected from patients at diagnosis and at routine clinical follow-up. Patients can be up to five years from diagnosis. The source of blood found to be most optimal for measuring the miR levels is Stage 1 will be collected. The final design of the Stage 2 study will be decided after completion of the Stage 1 study.
This phase II trial studies how well ibrutinib and blinatumomab work in treating patients with B acute lymphoblastic leukemia that has come back or is not responding to treatment. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as blinatumomab, may interfere with the ability of cancer cells to grow and spread. Giving ibrutinib and blinatumomab may work better in treating patients with relapsed or refractory B acute lymphoblastic leukemia.
