Filter by:To evaluate the outcome of a prednisolone and low dose methotrexate based protocol in Down syndrome children with ALL (DS-ALL) in an Asia-wide study. The treatment protocol was modified based upon backbone of Taiwan Pediatric Oncology Group (TPOG)-ALL protocol in which risk classification will be guided by level of flow minimal residual disease (MRD) instead.
This is a single center,randomized ,two-cohorts, open-label ,phase 1/2 study to evaluate the efficacy and safety of T cells expressing CD19 chimeric antigen receptors treatment for relapsed/refractory CD19+ acute lymphoblastic leukemia patients.
This phase II trial studies how well blinatumomab, methotrexate, cytarabine, and ponatinib work in treating patients with Philadelphia chromosome (Ph)-positive, or BCR-ABL positive, or acute lymphoblastic leukemia that has come back or does not respond to treatment. Immunotherapy with monoclonal antibodies, such as blinatumomab, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as methotrexate and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Ponatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving blinatumomab, methotrexate, cytarabine, and ponatinib may work better in treating patients with acute lymphoblastic leukemia.
This randomized phase II trial includes a blood stem cell transplant from an unrelated donor to treat blood cancer. The treatment also includes chemotherapy drugs, but in lower doses than conventional (standard) stem cell transplants. The researchers will compare two different drug combinations used to reduce the risk of a common but serious complication called "graft versus host disease" (GVHD) following the transplant. Two drugs, cyclosporine (CSP) and sirolimus (SIR), will be combined with either mycophenolate mofetil (MMF) or post-transplant cyclophosphamide (PTCy). This part of the transplant procedure is the main research focus of the study.
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 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.
This is a single arm, open-label, phase 1/2 study to evaluate the safety and efficacy of anti-CD19 CAR-T cells in patients with relapsed or refractory B cell Malignancies.
The GMALL registry serves the purpose of ALL research and quality assurance. The Registry collects data about diagnostics, treatment and outcome of Adult ALL Patients in the clinical routine, whether or not the patient is treated within a clinical trial.
This is a single arm, open-label, multi-center study to determine the efficacy and safety of an experimental therapy called CART-19 in patients with chemo-refractory and relapsed B-cell ALL.
