Primary outcomePrimary: Occurrence of Moderate and Severe Chronic GVHD at One Year Post Transplant — 0; 8 Participants
Summary
The purpose of this study is to investigate whether the combination of cyclophosphamide and abatacept versus the treatment used in standard of care will reduce the incidence of moderate and severe chronic graft-versus-host disease (GVHD) following hematopoietic stem cell transplantation. GVHD occurs when the cells from your donor (the graft) see your body's cells (the host) as different and attack them.

- Inability to identify an 10/10 HLA-Matched Donor (related or unrelated) or a haploidentical donor
- Active malignant disease relapse
- Active, uncontrolled infection, uncontrolled cardiac angina, symptomatic congestive heart failure
- Life expectancy <3 months
- Pregnancy or lactation
- Patients may not be receiving any other investigational agents in the last 28 days
- Patients with chronic myeloid leukemia in first chronic phase
