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 and Abatacept | The GVHD prophylaxis regimen on the experimental arm will consist of high dose Cyclophosphamide on Days +3 and +4 followed by abatacept for 6 months. Abatacept at a dose of 10mg/kg will be administered on days +5, +14 and +28, +56, +84, +112, +140, +168~Cyclophosphamide: Day 3 and day 4 following transplant. Dosing will be based on patients' actual weight up to 120% of ideal body weight, above which it will be based on adjusted ideal body weight (ideal weight plus 50% of the difference between ideal and actual weight).~abatacept: Abatacept at a dose of 10mg/kg will be administered on days +5, +14 and +28, +56, +84, +112, +140, +168 | 2 | 25 | EG000 |
| Group 2 | Methotrexate and Tacrolimus | The GVHD prophylaxis regimen on the standard of care arm will consist of methotrexate on Days +1,+3, +6 and +11 and tacrolimus~Methotrexate: standard of care Methotrexate 5 mg/m2 on Days 1, 3, 6 and 11~Tacrolimus: Tacrolimus per institutional guidelines | 3 | 15 | EG001 |
