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 | Arm I (Low Risk for Graft Failure) | Patients receive a conditioning regimen comprising fludarabine phosphate IV over 1 hour QD on days -6 to -2 and treosulfan IV over 120 minutes on days - 6 to -4. Patients undergo TBI on day -1. Patients then undergo donor UCBT on day 0.~Patients receive GVHD prophylaxis comprising cyclosporine IV over 1 hour or PO 2-3 times daily on days -3 to 100, followed by a taper in the absence of GVHD. Patients also receive mycophenolate mofetil IV 3 times daily on days 0 to 40, followed by a taper in the absence of GVHD.~Cyclosporine: Given IV or PO~Fludarabine Phosphate: Given IV~Laboratory Biomarker Analysis: Correlative studies~Mycophenolate Mofetil: Given IV~Total-Body Irradiation: TBI administered day -1: 200 cGy (or escalated to 300 cGy, 400 cGy, or 450 cGy per protocol statistical section)~Treosulfan: Given IV~Umbilical Cord Blood Transplantation: Undergo single or double unit UCBT | 36 | 66 | OG000 |
| Group 2 | Arm II (High Risk for Graft Failure) | Patients receive a conditioning regimen, TBI, donor UCBT, GVHD prophylaxis, and mycophenolate mofetil as in Arm I.~Cyclosporine: Given IV or PO~Fludarabine Phosphate: Given IV~Laboratory Biomarker Analysis: Correlative studies~Mycophenolate Mofetil: Given IV~Total-Body Irradiation: TBI administered day -1: 200 cGy (or escalated to 300 cGy, 400 cGy, or 450 cGy per protocol statistical section)~Treosulfan: Given IV~Umbilical Cord Blood Transplantation: Undergo single or double unit UCBT | 37 | 64 | OG001 |

- Title
- Number of Participants With Acute Graft-versus-host Disease (GVHD) Grade II-IV by Day 100
- Description
Grade I GVHD is characterized as mild disease, grade II GVHD as moderate, grade III as severe, and grade IV life-threatening. Diagnosing and grading acute GVHD is based on clinical findings (the organ stage, response to treatment and whether GVHD was a major cause of death) and frequently varies between transplant centers and independent reviewers.
