Description
Summary
This study will evaluate the safety, tolerability, and efficacy of an engineered donor graft ("Orca-T", a T-cell-Depleted Graft With Additional Infusion of Conventional T Cells and Regulatory T Cells) in participants undergoing myeloablative allogeneic hematopoietic cell transplant transplantation for hematologic malignancies.

Open to people ages 18-75
Recipients must meet all of the following criteria:
- Patients must diagnosed with one of the following histopathologically confirmed diseases, for which a myeloablative hematopoietic stem cell transplant (HCT) is planned:
- acute myeloid, lymphoid or mixed phenotype leukemia that is not in CR/CRi [Ages 18-65]
- myelodysplastic syndromes with > 10% to < 20% bone marrow blast burden [Ages 18-65]
- acute myeloid, lymphoid or mixed phenotype leukemia that is in CR/CRi but is categorized as DRI very high risk [Ages 18-65]
- Myelofibrosis [Ages 18-65]
- Blastic Plasmacytoid Dendritic Cell Neoplasm [Ages 18-65]
- acute myeloid, lymphoid, mixed phenotype leukemia or myelodysplastic syndromes (therapy-related/secondary MDS or eligible for alloHCT per 2017 International Expert Panel) that are in CR and intermediate to high risk per the DRI in patients aged 66 to 75 [Ages 66-75]
- chronic myeloid leukemia that is in chronic phase with history of blast crisis or accelerated phase and/or is resistant to or intolerant of >1 first- or second-generation TKI [Ages 18-65]
- Patients must be matched to a 8/8 HLA-matched related or unrelated donor
- Estimated glomerular filtration rate (eGFR) > 50 mL/minute
- Cardiac ejection fraction at rest ≥ 45% or shortening fraction of ≥ 27% by echocardiogram or radionuclide scan (MUGA)
- Diffusing capacity of the lung for carbon monoxide (DLCO) (adjusted for hemoglobin) ≥ 50%
- Total bilirubin < 2 times upper limit of normal (ULN) (patients with Gilbert's syndrome may be included where hemolysis has been excluded) and ALT/AST < 3 times ULN
