Reduced toxicity conditioning regimen (thiotepa, busulfan, fludarabine and ATG) followed by unrelated cord blood allogeneic stem cell transplant for high risk myeloïd malignancies.

The conditioning regimen will include:

* IV Thiotepa (5 mg/Kg/day for 2 days) (Day -7 and -6)
* IV fludarabine (40 mg/m²/day for 4 days) (from Day-5 to day -2)
* IV Busulfan (Busilvex 130 mg/m2/day for 3 days) (Day-5, -4 and -3)
* IV Anti-thymocyte globuline (Thymogobuline®, 2.5 mg/kg/day for 2 days) (Day-3 and -2)

In patient with co-morbidities and/or older than 60 years, conditioning could be reduced after consulting the coordinator of the study:

* IV Thiotepa (5 mg/Kg/day for 2 days) (Day -6)
* IV fludarabine (40 mg/m²/day for 4 days) (from Day-5 to day -2)
* IV Busulfan (Busilvex 100 mg/m2/day for 3 days) (Day-5, -4 and -3)
* IV Anti-thymocyte globuline (Thymogobuline®, 2.5 mg/kg/day for 2 days) (Day-3 and -2)

Allogeneic cord blood stem cell transplantation is a potentially curative therapy for patients with haematological malignancies. We have extensive experience with the use of Cord Blood Transplantation (CBT) in patients with advanced myeloid malignancies. In adults however, the 40% Non-Relapse Mortality (NRM) rate observed after CBT conditioned with a myeloablative conditioning has encouraged the development of CBT with Reduced Intensity Conditioning (RIC). Our previous national CBT protocol (the Minicord French protocol - NCT00797758) showed that RIC CBT can reduce NRM, but relapse remains the main post-transplant event (\>30% at one year). Thus, the development of reduced toxicity rather than RIC conditioning for CBT is warranted in order to improve the outcome of such transplants by limiting NRM and reducing relapse rate. The Fludarabine, ATG and intensified doses of IV Busulfan (9.6 mg/Kg total dose) regimen is a well-established preparative regimen for reduced-intensity/toxicity conditioning prior to allogeneic stem cell transplantation using peripheral blood stem cells mobilized with G-CSF (ClinicalTrials.gov Identifier: NCT00841724). However, such regimen is likely not sufficient to allow for CB cell engraftment. Thiotepa is an alkylating and radio-mimetic agent with a large anti-tumor activity including leukemic cells, the ability to cross the blood-brain barrier and to improve engraftment of hematopoietic stem cells. This drug has been combined to usual conditioning regimen without increasing the toxicity but improving the engraftment rate and potentially reducing the relapse rate. Thus, in the context of adult CBT for high risk myeloid malignancies, we propose to prospectively evaluate a reduced toxicity conditioning based on the association of Thiotepa, Fludarabine, IV Busulfan and ATG with the objective to achieve acceptable NRM rates, and to allow for improved anti-leukemic control based on the cytotoxic component of the conditioning regimen itself, while waiting for the long term immune-mediated disease control (GVL effect).
