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 | Patients With DC | Patients with dyskeratosis congenita (DC). Patients are treated with alemtuzumab (Campath 1H), Cyclophosphamide, Fludarabine, total body irradiation and stem cell transplantation.~Campath 1H: 10, 9, 8, 7, and 6 days before transplant subjects will be given 1 dose of campath 1H given via catheter (0.2 mg/kg over 2 hours).~Cyclophosphamide: 7 days before the transplant, 1 dose of cyclophosphamide is given via catheter (50mg/kg IV over 2 hours).~Fludarabine: 6, 5, 4, 3, and 2 days before the transplant, 1 dose fludarabine is given via catheter (40 mg/kg IV over 1 hour)~Total Body Irradiation: 1 day before the transplant one dose (200 cGy) of total body irradiation is given~Stem Cell Transplantation: Infusion of stem cells on Day 0. | 12 | 15 | OG000 |
| Group 2 | Patients With SAA | Patients with severe aplastic anemia (SAA). Patients are treated with alemtuzumab (Campath 1H), Cyclophosphamide, Fludarabine, antithymocyte globulin, total body irradiation and stem cell transplantation.~Cyclophosphamide: 7 days before the transplant, 1 dose of cyclophosphamide is given via catheter (50mg/kg IV over 2 hours).~Fludarabine: 6, 5, 4, 3, and 2 days before the transplant, 1 dose fludarabine is given via catheter (40 mg/kg IV over 1 hour)~Total Body Irradiation: 1 day before the transplant one dose (200 cGy) of total body irradiation is given~Stem Cell Transplantation: Infusion of stem cells on Day 0.~antithymocyte globulin: ATG (rabbit) 3 mg/kg for 3 days.~Methylprednisolone: 2mg/kg IV is given before each dose of ATG. | 19 | 21 | OG001 |
