Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Cyclophosphamide rATG/HSCT | Conditioning regimen will be 200 mg/kg of intravenous cyclophosphamide given in 4 equal fractions on days -5 through -2 with IV mesna. Rabbit antithymocyte globulin (rATG) (Thymoglobulin®) will be dosed at 0.5 mg/kg on day-5 and then 1.5 mg/kg from day-4 thru day -1. Methylprednisolone 1000 mg will be used infused intravenously before each dose of rATG. Peripheral blood stem cells (PBSC) will be infused intravenously on day 0. Filgrastim 5-10 mcg/kg will be started on day + 5 and continued until neutrophil engraftment.~Peripheral Blood Stem Cells: Mobilized leukapheresis product~Cyclophosphamide: Alkylating agent~Mesna: Used to decrease the risk of hemorrhagic cystitis~rATG: Immunosuppressive agent which contains antibodies specific to the antigens~Methylprednisolone: Steroid~Filgrastim: Granulocyte-colony stimulating factor (G-CSF); a glycoprotein that stimulates the bone marrow to produce granulocytes and stem cells | 22 | 22 | OG000 |
| Group 2 | Cyclophosphamide rATG/Fludarabine/HSCT | Conditioning regimen will be 120 mg/kg of intravenous cyclophosphamide given in 2 equal fractions on days -3 and -2 with intravenous mesna. Rabbit antithymocyte globulin (rATG) (Thymoglobulin®) will be dosed at 0.5 mg/kg on day-5 and then 1.5 mg/kg from day-4 thru day -1. Fludarabine 30 mg/m2 will be given IV on days -5, -4, and -3. Methylprednisolone 1000 mg will be used infused intravenously before each dose of rATG. PBSC will be infused intravenously on day 0. Filgrastim 5-10 mcg/kg will be started on day + 5 and continued until neutrophil engraftment.~Peripheral Blood Stem Cells: Mobilized leukapheresis product~Cyclophosphamide: An alkylating agent which causes prevention of cell division by forming adducts with DNA~Mesna: Medication used to decrease the risk of hemorrhagic cystitis prophylaxis~rATG: A predominantly lymphocyte-specific immunosuppressive agent which contains antibodies specific to the antigens commonly found on the surface of T cells~Methylpredni | 21 | 22 | OG001 |
