What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this study is to determine if a search strategy of searching for an HLA-matched unrelated donor for allogeneic transplantation if possible then an alternative donor if an HLA-matched unrelated donor is not available versus proceeding directly to an alternative donor transplant will result in better survival for allogeneic transplant recipients within 2 years after study enrollment.

Are You a Good Fit for This Trial?

This trial is for patients with conditions like various leukemias, lymphomas, sickle cell disease, and aplastic anemia who need a stem cell transplant but don't have a closely matched family donor. They should be fit for transplantation based on their medical history and tests. Patients already having had an allogeneic transplant can't join.

Inclusion Criteria

I have a family member who could be a donor but is deemed unsuitable by the medical center.

I am deemed fit for a transplant from another person based on my health records and tests.

Patients may co-enroll with other interventional or observational studies

Exclusion Criteria

Previous formal unrelated donor search

I have not had a transplant from another person.

What Are the Treatments Tested in This Trial?

Interventions

• Donor Search Prognosis Score

Trial Overview The study aims to see if searching for a fully matched unrelated donor before considering alternative donors leads to better survival within two years after joining the study compared to going straight to an alternative donor transplant.

How Is the Trial Designed?

Group I: Donor Search Prognosis: MUD Very Unlikely Experimental Treatment 1 Intervention

Patients who are Very Unlikely to find a MUD, defined as having a \<10% chance of finding an 8/8 HLA-matched unrelated donor, for whom a haploidentical, cord blood, or mismatched unrelated donor transplant will be pursued.

Group II: Donor Search Prognosis: MUD Very Likely Experimental Treatment 1 Intervention

Patients who are Very Likely to find a matched unrelated donor (MUD), defined as having a \>90% chance of finding an 8/8 HLA-matched unrelated donor, for whom a fully matched unrelated donor will be pursued.

Group III: Donor Search Prognosis: MUD Less Likely Experimental Treatment 1 Intervention

Patients with a Less Likely chance of finding a MUD, i.e., those not falling into the other two groups (a 26% chance), will be enrolled onto the observational component of the study and analyzed for all relevant endpoints but will not be included in the primary comparison.
