Trial summary

Background: People who have certain immune system diseases often need a procedure called allo HSCT. This is short for allogeneic hematopoietic stem cell transplant. This might cure people with these diseases. Many people who need allo HSCT need donors who are relatives with similar genes. Read more about this study

About this study

Official title: Retrospective Study of the Breadth of Donor Options for Patients With Inherited Diseases Requiring Allogeneic Hematopoietic Stem Cell Transplant in the Era of Alternative Donor Transplants Using Post-Transplantation Cyclophosphamide

Background:

People who have certain immune system diseases often need a procedure called allo HSCT. This is short for allogeneic hematopoietic stem cell transplant. This might cure people with these diseases. Many people who need allo HSCT need donors who are relatives with similar genes. But the disease may also affect those in the donor pool. This may mean there are fewer options for people with inherited diseases. Researchers want to collect data on how transplant candidates and their donors are found.

Objective:

To find out how genetic diseases and the ways they are inherited affect the breadth of options for allo HSCT donors.

Eligibility:

Records from studies that have already been done. These will be for people ages 4 and older who were evaluated for allo HSCT or to be donors.

Design:

Participants already signed a consent form for their records to be shared.

Researchers will study the participant data.

Data will be stored in an electronic system. Researchers will use passwords to protect the data.

Read the detailed description

This protocol is a retrospective review of donor search results for patients with inherited immunodeficiency diseases requiring allogeneic hematopoietic stem cell transplant (allo HSCT).

The study will involve collecting information related to the donor search for transplant candidates and their prospective donors, using records in CRIS, Crimson, the HLA lab, and records in the transplant coordinator office (such as shipping logs of HLA typing kits). The study will not involve the use of specimens or participant contact.

The participants whose records will be reviewed will be those who were evaluated for allo HSCT or donation on an NIH primary immunodeficiency transplant protocol at a time when haplo donors were eligible (March 30, 2012 to present for GATA2, January 1, 2015 for CGD, October 6, 2015 to present for 16-C-0003, and May 21, 2014 to present for DOCK8).

The Principal Investigators on the included protocols have granted permission to conduct this study and have verified that none of the original protocols or informed consent documents preclude such a review of clinical data.

Questions about this trial

What is this clinical trial studying?

An observational study of Primary T-cell Immunodeficiency Disorders and Common Variable Immunodeficiency, run by National Cancer Institute (NCI) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 21 Feb 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To determine the impact of genetic diseases and their modes of inheritance on the breadth of allo HSCT donor options (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03188419, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Feb 2020; AzTrials last refreshed its copy on 7 Nov 2026.
