Filter by:Bone marrow transplantation (BMT) is a risky procedure. If doctors could reduce the complications, BMT would be safer to use for a wider range of conditions. The purposes of this study are - to prevent graft rejection by increasing the amount of immunosuppression and by giving some lymphocytes from the donor before transplant; - to prevent graft-versus-host disease (GVHD) by transplanting T-cell depleted stem cells; - to improve the immune effect against residual leukemia by the add-back of donor lymphocytes before transplant and six or more weeks after transplant. Beyond the standard transplant protocol, study participants will undergo additional procedures. First, along with total body irradiation, patients will receive two drugs (a high dose of cyclophosphamide and fludarabine) to suppress immunity and prevent rejection of the transplant. Second, four days before the transplant, patients will be given donor lymphocytes that have been irradiated to make them incapable of causing GVHD. On the day of the transplant, patients will receive an infusion of T-cell depleted bone marrow stem cells. Finally, patients will receive two doses of add-back donor T-cells (45 and 100 days post transplant) and the immunosuppressive drug cyclosporine starting on day 44 until about six months after transplant. Study participants must be between the ages of 10 and 56 and have a family member who is a suitable stem cell donor match.
The pharmacokinetic behavior of vincristine in pediatric patients has not been well characterized. The present study will obtain detailed information on vincristine pharmacokinetics in patients being treated for standard risk ALL on CCG protocols 1952/1962. A limited sampling strategy will be developed, and the interpatient and intrapatient variability of vincristine pharmacokinetics in children will be studied. A correlation between vincristine neurotoxicity and vincristine pharmacokinetics will be sought.
