Spots Global Cancer Trial Database for Umbilical Cord Blood Transplant for Children With Lymphoid Hematological Malignancies

Study Description

Brief Summary: The purpose of this study is to determine the safety and effectiveness of UCBT to treat patients with lymphoid hematological diseases and to see if this treatment can decrease the incidence of leukemia relapse, GVHD and infections. These patients have a type of blood cell disorder that is very hard to cure. This treatment that is being used in this trial is known as a stem cell transplant. This treatment might help the patient live longer without the disease. It uses much stronger doses of drugs and radiation to kill the diseased cells that could be given without the transplant. We also think that the healthy cells from the donor may help fight any diseased cells left after the transplant. For the transplant to take place, we will administer stem cells from a 'donor' whose cells best 'match' the patient's. In this study umbilical cords will be the source of the stem cells. Before the transplant, two very strong drugs plus total body irradiation will be given to as preconditioning. This treatment will kill most of your blood-forming cells in the bone marrow. The patient will then get then healthy stem cells. If the patient has the disease in the central nervous system (CNS), they will receive radiation to the head and spine before starting the conditioning. This is to try to get disease control in the CNS. Radiation will not be given for children under 2 yrs old. Currently, many umbilical cord blood units are available in public banks for transplantation in patients lacking bone marrow donors. UCB transplants (UCBT) may offer several advantages over adult bone marrow or peripheral blood stem cell transplants, including: 1. rapid availability, 2. absence of donor risk, 3. low risk of transmissible infectious diseases, 4. low risk of acute GvHD (Graft vs. Host Disease) The three main causes of death after umbilical cord blood transplantation for these kind of disorders are graft failure, infection and disease relapse. In this study we are trying to address these three problems: To help improve engraftment we will add the drug Fludarabine to Cytoxan and total body irradiation. Fludarabine is a very strong medicine. We will try to decrease infections and reduce leukemia relapse by using fludarabine instead of antithymocyte globulin (ATG).

Detailed Description: After the eligible criterion for treatment has been met and a suitable UCB stem donor has been found, the patient will have a central line placed. Research Therapy: After placement of the central line, the following chemotherapy will be given to after admission to the hospital and before the infusion of the umbilical cord blood stem cells: * 9 - 6 days before the infusion: Total Body Irradiation (TBI) in two fractions ("doses") per days. * 5 - 2 days before the infusion: Cytoxan given daily for 4 days, over 1 hour as an intravenous infusion. Mesna will be given per standards. Mesna is a drug given to decrease the side effects of Cytoxan. It will be given daily as an intravenous infusion while the patient receives the Cytoxan. * 4 - 2 days before the infusion: Fludarabine given daily for 3 days over 1 hour as an intravenous infusion. Stem cell transplant (intravenous infusion of the UCB stem cells) - defined as day 0 of the treatment. All other "numbered" days relate to this infusion date. For example, Day 1 is the first day after the stem cell transplant. The following medications will be given to help decrease side effects from the chemotherapy and UCB infusion: Cyclosporine A (CSA) will be given starting 3 days prior to the stem cell infusion. It will be given daily over 2 hours every 12 hours, after the infusion and then tapered if no GVHD is present. Administration of Mycophenolate mofetil (MMF) will start on the day the stem cell infusion is completed and will continue daily for 45 days, unless the patient develops GvHD. Intravenous immunoglobulin's (IVIG) will be given monthly until GVHD therapy is stopped and there is evidence that the patient's body is producing antibodies. Study Evaluations: Various study evaluations will be performed before and during the trial. Follow Up: After year 1, the patient will be asked to return to the clinic once a year for consultations and bone marrow tests. A follow up bone marrow biopsy and aspirate will be done 1 and 2 years after transplant. Consultations with specialists will be similar to the ones the patient had before the transplant.
