View clinical trials related to Acute Lymphocytic Leukemia.
Filter by:Patients on this study have a type of lymph gland cancer called non-Hodgkin Lymphoma, Acute Lymphocytic Leukemia, or chronic Lymphocytic Leukemia (these diseases will be referred to as "Lymphoma" or "Leukemia"). Their Lymphoma or Leukemia has come back or has not gone away after treatment (including the best treatment known for these cancers). This research study is a gene transfer study using special immune cells. The body has different ways of fighting infection and disease. No one way seems perfect for fighting cancers. This research study combines two different ways of fighting disease, antibodies and T cells, hoping that they will work together. Antibodies are types of proteins that protect the body from bacterial and other diseases. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells including tumor cells. Both antibodies and T cells have been used to treat patients with cancers; they have shown promise, but have not been strong enough to cure most patients. T lymphocytes can kill tumor cells but there normally are not enough of them to kill all the tumor cells. Some researchers have taken T cells from a person's blood, grown more of them in the laboratory and then given them back to the person. The antibody used in this study is called anti-CD19. It first came from mice that have developed immunity to human lymphoma. This antibody sticks to cancer cells because of a substance on the outside of these cells called CD19. CD19 antibodies have been used to treat people with lymphoma and Leukemia. For this study anti-CD19 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 laboratory, investigators have also found that T cells work better if they also put a protein that stimulates T cells called CD28. Investigators hope that adding the CD28 might also make the cells last for a longer time in the body. These CD19 chimeric receptor T cells with C28 T cells are investigational products not approved by the Food and Drug Administration. The purpose of this study is to find the biggest dose of chimeric T cells that is safe, to see how the T cell with this sort of chimeric receptor lasts, to learn what the side effects are and to see whether this therapy might help people with lymphoma or leukemia.
ALL patients aged 55 years or older were treated with steroids during one week and Ph+ve cases were then offered a specific therapy including an induction treatment with steroids, cyclophosphamide, daunorubicin and vincristine, followed, irrespective of response to induction chemotherapy, by imatinib, 600 mg daily, combined with intermittent steroids during 2 months. Patients in complete response (CR) were then given 10 blocks of alternating chemotherapy, including 2 additional two-month blocks of imatinib, for a total treatment duration of 2 years. Therapy of occult central nervous system leukemia included 5 intrathecal injections of methotrexate and cranial irradiation. Duration of therapy : 2 years.
Recent studies of conventional chemotherapy for infants with high-risk hematologic malignancies show that the long-term disease-free survival is low. Although blood and marrow stem cell transplantation using an HLA identical sibling has improved the outcome for these children, less than 25% have this donor source available. Another option is haploidentical transplantation using a partially matched family member donor (i.e. parental donor). Although haploidentical transplantation has proven curative for some patients, this procedure has been hindered by significant complications, primarily regimen-related toxicity including infection and graft versus host disease (GVHD). Building on prior institutional trials, this study will provide patients a haploidentical graft depleted of T lymphocytes using the investigational device, CliniMACS selection system. One week after the transplant procedure, patients will also receive an infusion of additional donor derived white blood cells called Natural Killer (NK) cells in an effort to decrease risks for rejection of the graft, disease relapse, and regimen related toxicity. The primary objective of the study is to evaluate 1 year survival in infants with high risk hematologic malignancies who receive this study treatment.
