Summary
Brief summary (as posted)
Unrelated cord blood transplantation (UCBT) has been used for several years when there is no HLA identical sibling or unrelated donor.Since the recent publication of encouraging results after transplantation of two UCB units, the number of these double-transplantations increases in a very significant way.However, there is currently no prospective study comparing in a reliable way the double-transplantation to single-transplantation results.The investigators propose a prospective and randomized study comparing the results of single versus double unit UCBT in children and young adults (\< 35 yrs) with acute leukemia in remission. This is an open, multicenter study carried out in the allogeneic transplant centers from the French society for hematopoietic stem cell transplantation and cell therapy. The primary objective is to compare the incidence of transplantation failure in the two treatment arms. Transplantation failure, the primary endpoint of the study, is defined by the occurrence of one of the following events : transplant-related death, second allogeneic transplantation or autologous backup infusion for primary engraftment failure, autologous recovery. The financial impact of these double-transplantations being to date unknown, the project also includes a cost-effectiveness study, the effectiveness criterion being a decrease in transplantation failure incidence. The secondary clinical endpoints are: overall survival and disease-free survival, relapse incidence, transplant-related mortality, incidence of severe infections and GvHD. The secondary biological endpoints are: hematological and immunological recovery, post transplant chimerism.

- Double unit unrelated cord blood transplantation
- description
- Transplantation of unrelated cord blood units is done at least 24 hours after last chemotherapy and carried out during the same day. The unit presenting the best degree of HLA compatibility with the patient will be transfused in first. If the 2 units have the same degree of HLA compatibility with the recipient, the unit with the higher cell dose will be transfused in first. A 2 hours time interval between the 2 transfusions will be respected.
