Brief Summary:
Stem cell transplant is an important therapeutic option for pediatric patients with relapsed or refractory leukemia. Although, full myeloablative transplants are widely used for patients with acute leukemia, myeloablative chemo-radiotherapy may not be feasible in some specific settings. These settings include 1) patients with pre-existing health issues and organ toxicities; 2) patients who have relapsed post-ablative transplant and need a second stem cell transplant; and 3) leukemia patients with advanced disease who have been heavily pre-treated. Clofarabine, a new purine nucleoside anti-metabolite, has the advantage of significant antileukemic activity in addition to its possible immuno-suppressive properties. In this study we plan to determine the maximum feasible dose (MFD) of Clofarabine in combination with total body irradiation that can achieve durable donor engraftment without causing excessive toxicity.
Detailed Description:
Standard non-myeloablative regimens use Fludarabine and low dose total body irradiation (TBI) as pioneered by the Seattle group. Fludarabine is mainly used for its immuno-suppressive properties and has limited anti-leukemic effects. Since, the non-myeloablative and RIC regimens do not include intensive chemotherapy; relapse rates can be higher in RIC regimens compared to full myeloablative regimens. One way to improve overall survival in non-myeloablative / RIC setting is to add more effective anti-leukemia agents to prevent post-transplant relapses, without increasing TRM. Clofarabine, a new purine nucleoside anti-metabolite, has the advantage of significant antileukemic activity in addition to its possible immuno-suppressive properties. Combining Clofarabine with low dose TBI as a non-myeloablative preparative regimen may improve overall outcomes of SCT in advanced hematological malignancies. Therefore, in this study we plan to determine the maximum feasible dose (MFD) of Clofarabine in combination with 2Gy TBI that can achieve durable donor engraftment without causing excessive toxicity. The MFD determined from this pilot will be used in the next phase to study the outcomes after using this combination for SCT in this very high risk population.
