Haploidentical bone marrow transplant for severe aplastic anemia

A Study of T-Cell Replete, HLA-Mismatched Haploidentical Bone Marrow Transplantation With Post-Transplant Cyclophosphamide for Patients With Severe Aplastic Anemia Lacking HLA-Matched Related Donor

Phase 2 Interventional Northside Hospital, Inc. · NCT02828592

This study is testing if a special type of bone marrow transplant from a mismatched donor can help people with severe aplastic anemia who don't have a matching donor.

What this trial studies

This clinical trial aims to evaluate the effectiveness of haploidentical bone marrow transplantation in patients with severe aplastic anemia who lack suitable HLA-matched donors. Participants will undergo a preparative regimen involving Fludarabine, Cyclophosphamide, and Total Body Irradiation, followed by transplantation from a mismatched donor. Post-transplant, Cyclophosphamide will be administered to reduce the risk of graft failure. The study will assess the graft failure rate and overall patient outcomes to determine the viability of this approach.

Who should consider this trial

Good fit: Ideal candidates include patients aged 65 or younger with severe aplastic anemia who have a suitable haploidentical donor.

Not a fit: Patients with poor cardiac, pulmonary, liver, or renal function, or those who have previously undergone an allogeneic transplant may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new option for patients with severe aplastic anemia who do not have matched sibling donors, potentially improving survival rates.

How similar studies have performed: Other studies have shown promising results with haploidentical transplantation, indicating that this approach may be effective for treating severe aplastic anemia.
