This study will evaluate the safety, tolerability, and efficacy of engineered donor grafts
("OrcaGraft"/"Orca-Q") in participants undergoing myeloablative allogeneic hematopoietic cell
transplant transplantation for hematologic malignancies.


  1. Age = 18 and = 65 years at the time of enrollment
  2. Diagnosed acute myeloid, lymphoid or mixed phenotype leukemia, or high or very high risk myelodysplasic syndrome (MDS) or Myelofibrosis
  3. Planned to undergo myeloablative allogeneic hematopoietic stem cell transplant (HCT)
  4. Matched to a related or unrelated donor or to a haploidentical donor
  5. Estimated glomerular filtration rate (eGFR) > 50 mL/minute
  6. Cardiac ejection fraction at rest = 45% or shortening fraction of = 27% by echocardiogram or radionuclide scan (MUGA)
  7. Diffusing capacity of the lung for carbon monoxide (DLCO) (adjusted for hemoglobin) = 50%
  8. Total bilirubin < 1.5 times upper limit of normal (ULN) (< 3 times if attributed to Gilbert's syndrome) and ALT/AST < 3 times ULN

**Clinical trials are research studies that involve people. These studies test new ways to prevent, detect, diagnose, or treat diseases. People who take part in cancer clinical trials have an opportunity to contribute to scientists’ knowledge about cancer and to help in the development of improved cancer treatments. They also receive state-of-the-art care from cancer experts... Click here to learn more about clinical trials.
