Clinical Trial Summary

The purpose of this study is to estimate overall survival (OS) for participants treated with abatacept versus those not treated with abatacept prior to hematopoietic stem cell transplantation (HSCT). Participants were included if their donors were unrelated and had 1-allele mismatched human leukocyte antigen (HLA) status.

• Gender: All
• Age group: 6 Years and older

Eligibility

Inclusion Criteria:

• Participants with cord blood grafts
• Participants with non-MDS myeloproliferative disorders (NOTE: Participants with chronic myelomonocytic leukemia [CMMoL] will be included)
• Participants who did not consent to participate in research
• Participants treated at embargoed centers for research
• Participants treated with abatacept and ATG
• Among non-abatacept treated participants, participants transplanted at centers with abatacept trial participants
• Participants with any of the following missing propensity score variables:

• Age
• Gender (male, female)
• HSCT graft source (bone marrow [BM], peripheral blood [PB])
• Conditioning intensity (myeloablative, non-myeloablative / reduced intensity)
• Karnofsky/Lansky Performance Score (80%, 90-100%)
