ABBA CORD: Double Umbilical Cord Blood Transplants With Abatacept for Graft Versus Host Disease Prophylaxis
Leland Metheny
Summary
The goal of this clinical trial is to see if adding abatacept to tacrolimus and MMF prevents or reduces the chances of acute graft versus host disease which is a complication that can occur after transplant in participants with blood cancer. The usual therapy for graft versus host disease prevention after a cord blood transplant includes tacrolimus and MMF. The main question this clinical trial aims to answer is whether or not abatacept will be safe and effective in reducing aGVHD rates in dCBT. Participants will: * Partake in exams, tests, and procedures as part of usual cancer care. * Partake in conditioning, which is the treatment that is given before a transplant. * Have a cord blood transplant. * Partake in radiation following the transplant.
Description
Cord blood (CB) is a valuable alternative graft source for patients with hematologic malignancies in need of allogeneic transplantation who lack human leukocyte antigen (HLA)-matched adult donors. In Black, Asian, Hispanic populations, the chance of finding a HLA matched donor is 23%, 41%, and 46%, respectively. CB allows for greater HLA difference between donor and recipient, and increases the availability of donors, and therefore transplant, to these populations. Retrospective analyses and prospective trials demonstrate that recipients of double CB transplant (dCBT) have a grade II-IV acute…

Interventions
- DrugCyclophosphamide
Cyclophosphamide (Cy) is one part of the conditioning regimen. 50 mg/kg beginning on day -6.
- DrugFludarabine
Fludarabine (Flu) is one part of the conditioning regimen. 150 mg/m2 (30 mg/m2 per day on days -6 to -2)
- DrugThiotepa
Thiotepa (Thio) is one part of the conditioning regimen.10 mg/kg (5 mg/kg per day on days -5 and -4)
- RadiationTotal Body Irradiation
400 cGy (200 cGy per day on days -2 and -1).
- BiologicalDouble Umbilical Cord Transplant
Cord blood is a regulated biologic. Selection of cord blood units will be based on published guidelines.
- DrugTacrolimus
Tacrolimus will be administered post transplant. Graft-versus-host disease prophylaxis will consist of tacrolimus and mycophenolate mofetil (MMF), starting on day-5. Tacrolimus will continue at least until day 180 and then be tapered off.
