Assessment of Chimerism and Relapse Post Bone Marrow/HCT Transplant Using AlloHeme Test ACROBAT

What's the purpose of this trial?

AlloHeme is a chimerism test service that utilizes NGS technology to analyze SNP loci to quantify donor and recipient cells by measuring genomic DNA. Before transplant, patient and donor peripheral blood sample will be collected to identify informative marker for routine chimerism testing and baseline establishment for AlloHeme. Post-transplant blood or bone marrow samples are obtained and compared to the baseline sample profiles to calculate % chimerism of recipient cells in the blood and/or bone marrow samples. Cell selection from blood and bone marrow samples is applied to evaluate chimerism in specific cell subtypes that are relevant to AML and MDS diseases (CD3+ T lymphocytes, CD33+ Myeloid cells and CD15+ Granulocyte cell subtypes from blood and CD34+ hematopoietic stem cells from bone marrow).

This trial is currently open and accepting patients.
