A Phase IB-II Study Of High-Dose Post-Transplant Cyclophosphamide, Abatacept, and Short-Duration Tacrolimus for the Prevention of Graft-Versus-Host Disease (GvHD) Following Haploidentical Hematopoietic Stem Cell Transplantation (HSCT)
In Brief
A Phase 2 clinical trial evaluating Cyclophosphamide, Abatacept, and Tacrolimus for GvHD Prevention for Graft-versus-host Disease. Completed, enrolled 46 participants across 1 site.
Detailed Summary
This is a single arm, open label, optimal 2-stage Simon design phase Ib-II clinical trial. Adult patients with hematological malignancies undergoing allogeneic HSCT from first- or second-degree haploidentical donor are eligible for the study if they meet the standard criteria defined in our institutional standard operation procedures (SOPs), meet all inclusion criteria, and do not satisfy any exclusion criteria. Patients will receive non-myeloablative, reduced-intensity or myeloablative conditioning regimen followed by peripheral blood hematopoietic stem cells. Patients will receive cyclophosphamide, abatacept, and short-duration tacrolimus for GvHD prophylaxis.
