Experimental
Experimental
Conditioning with CYC/ antithymocyte globulin (ATG)
Conditioning with CYC/Thiotepa/ATG
Each patient receives stem cell transplantation open label with cluster of differentiation (CD)34 selected stem cells mobilisation and conditioning depending on manifestation If cardiac manifestation: Conditioning with CYC 2 x 50mg + thiotepa 2x5mg + ATG If no cardiac manifestation: Conditioning with 4 x 50mg CYC + ATG
In patients with cardiac manifestations as defined in the protocol the conditioning for stem cell transplantation is changed to Cyclophosphamide (CYC), thiotepa and ATG
