This protocol will collect blood samples and medical information from patients who have had a bone marrow transplant using cells from an unrelated donor identified through the National Marrow Donor Program (NMDP). The NMDP has two programs in which patients can participate: the Research Database Program and the Research Sample Repository.

Patients who have received a bone marrow transplant at the NIH or other institution from an unrelated donor affiliated with the NMDP may be eligible for this study.

Participants in the NMDP Research Database program will have medical information about their disease and their transplant sent to the NMDP before and after the transplant and once a year for the rest of their life. The information will be used to help determine how well transplant recipients recover from their transplant, how recovery after a transplant can be improved, how access to transplant for different groups of patients can be improved and how well donors recover from collection procedures.

Participants in the NMDP Research Sample Repository program will have a small blood sample drawn from a vein in the arm just before they start taking medicines for the conditioning regimen to prepare them for the transplant. The blood samples will be used to look at ways to improve how patients are matched with their donors, to determine and evaluate the factors that affect transplant outcome, and to help develop methods to improve tissue matching between donors and recipients.

The National Institutes of Health (NIH) has entered into a Transplant Center Participation Agreement with the National Marrow Donor Program (NMDP). This agreement allows any NIH investigator with an NIH Institutional Review Board (IRB) approved protocol to secure hematopoietic stem cells (HSC) or cord blood units from the NMDP/CIBMTR registry for the purpose of transplanting patients who have no suitable matched related donors. As part of this agreement, the NMDP/CIBMTR Research Program requires that blood samples as well as baseline and outcome data (mainly demographic, quality of life, and clinical data) be collected and maintained in accordance with the NMDP/CIBMTR IRB approved protocols. The goal of the NMDP/CIBMTR Research Program is to improve the safety and effectiveness of unrelated donor HSC transplantation for both the donors and recipients, and to have a comprehensive source of data that can be used to study unrelated donor HSC transplantation. The NMDP/CIBMTR is the sole custodian of the data in the Research Database.

The primary purpose of this protocol is to incorporate all the NMDP/CIBMTR requirements for securing data and blood samples on recipients whose transplant was facilitated by NMDP/CIBMTR here at NIH as well as TED (Transplant Essential Data) level data submission for Allogeneic recipient patients and their donors. This protocol will include patients at the NIH that have enrolled in an NIH IRB approved protocol to receive related donor transplants as well as matched unrelated donor (MUD) HSC transplants or cord blood transplants facilitated by the NMDP/CIBMTR. It may also include patients that have undergone a MUD transplant at another approved transplant center but need to receive additional blood products from the donor while at NIH after completing a transplant center transfer. As of 03/02/2020, all newly enrolled subjects will only have TED level data submission to NMDP.

• INCLUSION CRITERIA:

Patients (Recipient):

Must be enrolled on an NIH IRB approved protocol which involves an HSC transplant or cellular therapy utilizing HSC from an unrelated donor affiliated with the NMDP.

May include recipients who have received an NMDP facilitated HSC transplant at other institutions, provided the patient consents to and completes a Transplant Center transfer.

Ability to comprehend and willing to sign the informed consent or have a parent/guardian consent if the donor is a minor; assent obtained from minors as appropriate.

Allogeneic (related matched) recipients for TED level data submission only.

Donors of related transplant.

EXCLUSION CRITERIA:

The patient has received an HSC transplant or cellular therapy utilizing HSC from an unrelated donor facilitated by a registry other than NMDP.

This protocol will include patients at the NIH that have enrolled in an NIH IRB approved protocol to receive related donor transplants as well as matched unrelated donor (MUD) HSC transplants or cord blood transplants facilitated by the NMDP/CIBMTR. It may also include patients that have undergone a MUD transplant at another approved transplant center but need to receive additional blood products from the donor while at NIH after completing a transplant center transfer
