- People diagnosed with acute myeloid leukemia, acute lymphoblastic leukemia, mixed phenotype leukemia, or high/very high risk myelodysplastic syndrome (MDS), where the disease is either in full remission or has a low level of abnormal cells in the bone marrow (no more than 10%)
- People for whom a stem cell transplant from a donor (called an allogeneic transplant) has been recommended by their doctor
- People who have a matched or partially matched donor — either related or unrelated — or a half-matched (haploidentical) related donor
- People whose kidneys are working above a minimum level of function (the specific threshold depends on the type of transplant — confirm with trial site)
- People whose heart is pumping adequately (at least 45% function for full-intensity transplant, or at least 40% for reduced-intensity transplant)
- People whose lungs are functioning above a minimum threshold (at least 50% for full-intensity transplant, or at least 40% for reduced-intensity transplant)
- People whose liver function blood tests are within acceptable ranges (the specific limits depend on the type of transplant — confirm with trial site)
- People enrolling in the reduced-intensity transplant arms must be assessed by the lead doctor as being unsuitable for a full-intensity transplant
Who may not be able to join:
- People who have previously had a donor stem cell transplant
- People currently taking corticosteroids (steroids) or other immune-suppressing medicines, with some exceptions — low-dose steroids (10 mg per day or less) or topical steroids may be allowed, as may treatments specifically approved for their blood condition
- People whose transplant plan includes a procedure called donor lymphocyte infusion (DLI)
- People whose transplant plan includes certain methods of removing or reducing T cells from the donor cells (such as post-transplant cyclophosphamide or alemtuzumab)
- People who have antibodies in their blood that react against their donor's tissue type (confirm with trial site)
- People with a low performance/fitness score below the required threshold (the minimum score depends on the type of transplant — confirm with trial site)
- People with a high level of health complications as measured by a transplant-specific scoring tool, above the allowed limit for their transplant type (confirm with trial site)
- People with an active, uncontrolled bacterial, viral, or fungal infection that is not improving with treatment at the time of enrolment
- People who test positive for HIV-1 or HIV-2, HTLV-1 or HTLV-2, active Hepatitis B, or Hepatitis C
- People with an uncontrolled autoimmune disease that currently requires immune-suppressing treatment
- People who have had another cancer within the past year, or have a current active cancer — with some possible exceptions for certain slow-growing blood cancers under monitoring only, subject to approval (confirm with trial site)

- People who are pregnant or breastfeeding
