NCT03904134

Brief Summary

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.

Study Arms (3)

Donor Search Prognosis: MUD Very Likely

OTHER

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.

Other: Donor Search Prognosis Score

Donor Search Prognosis: MUD Very Unlikely

OTHER

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.

Other: Donor Search Prognosis Score

Donor Search Prognosis: MUD Less Likely

OTHER

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.

Other: Donor Search Prognosis Score

Interventions

Patients will be placed on a study arm after receiving a Donor Search Prognosis Score, which is based on HLA allele frequencies and race/ethnicity. This score predicts the likelihood of successfully identifying a 10/10 matched unrelated donor.Worse search prognosis is associated with racial and ethnic minority status but not with other patient and disease biology characteristics that might influence the success of hematopoietic cell transplantation (HCT). Thus, the use of donor search prognosis in this trial as a tool for biologic assignment to matched unrelated donors vs. mismatched donors provides a mechanism to minimize bias from disease characteristics.

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Patients of all ages with AML, ALL, MDS, NHL, HL, AA, or SCD are eligible.
  • Any planned conditioning regimen and GVHD prophylaxis approach is eligible.
  • Patients must be considered suitable allogeneic transplant candidates at the time of enrollment based on medical history, physical examination, and available laboratory tests. Specific testing for organ function is not required for eligibility but, if available, these tests should be used by the treating physician to judge transplant suitability.
  • Patient and physician must intend to proceed with allogeneic HCT within the next 6 months if a suitable donor is identified.
  • Center plans to follow the algorithm for alternative donor identification: (a) for subjects who are Very Likely to find a MUD, attempt to identify a matched unrelated donor; (b) for a subjects who are Very Unlikely to find a MUD, proceed expeditiously to a haploidentical, cord blood or mismatched unrelated donor.
  • Signed informed consent, and assent if applicable. Consent may be signed prior to completion of family typing but patients will only be considered evaluable upon confirmation that there is no suitable HLA-identical or 1 allele or antigen mismatched related donor available.

You may not qualify if:

  • Prior allogeneic HCT (prior autologous transplant is allowed)
  • Previous formal unrelated donor search

Model Details: The primary comparison for the interventional study will be between two arms based on biologic assignment, analyzed on an intention-to-treat basis: Arm 1: 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; and Arm 2: 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. 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.
