Who may be able to join
- Subjects will be entered on this protocol at the time of their first visit to the NIH Clinical Center outpatient clinic or inpatient service if:
- The subject carries the diagnosis of a disorder for which the NHLBI has an active research protocol, and based on information received from an outside physician, he/she appears to meet at least preliminary eligibility criteria for that protocol
- OR
- The subject is a donor for a subject for whom the NHLBI has an active stem cell transplant protocol and based on information received from an outside physician, he/she appears to meet preliminary eligibility as a donor

About this study
Official title: Screening Protocol for Subjects Being Evaluated for National Heart, Lung and Blood Institute (NHLBI) Protocols
This study allows the evaluation of subjects in order to determine their ability to safely participate in other active research studies.
After subjects complete the screening process, they will be offered the opportunity to participate in an active research study, or if no appropriate studies are available information and recommendations will be provided for other treatment options.
Read the detailed description
This protocol is designed for screening of subjects before a decision can be made as to their eligibility for one of the active National Heart, Lung, and Blood Institute (NHLBI) research protocols. Its purpose is to allow detailed investigation into the hematologic or oncologic problems of these subjects, and the status of other organ systems that would determine their ability to safely tolerate specific aspects of active research protocols. It allows investigation as to whether a donor is HLA matched, fit to receive G-CSF, and fit to undergo apheresis and therefore eligible to participate as a donor on a bone marrow transplant protocol. It also allows the investigation as to whether subjects are eligible for participation as normal volunteer based on protocol eligibility criteria that requires generally good health status by history or physical exam findings, or laboratory assessments. After completion of this screening process, the subject will either be offered a chance to participate in an active research protocol, or if no appropriate protocol is identified, subjects with hematologic or oncologic disease will have recommendations for other treatment options relayed to the primary or referring physician.
Primary objective is to determine subject eligibility for participation on NHLBI protocols.
Primary endpoint is the results of clinical, imaging and laboratory assessments.

Questions about this trial
What is this clinical trial studying?
An observational study of Hematologic Disease and Disorders and Donors, run by National Heart, Lung, and Blood Institute (NHLBI) 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?
The sponsor lists 8 inclusion and 1 exclusion criteria. 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: enrolling by invitation, as of the sponsor's last update on 19 Oct 2026. 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?
This study is still under way. Results are not available in the source record yet.
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?
Primary endpoint is the results of clinical, imaging and laboratory assessments. (time frame: ongoing). 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 NCT00001620, which also lists 5 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 19 Oct 2026.
