Collection of Samples and Data for the National Marrow Donor Program Repository
NCT00495300 · View on ClinicalTrials.gov ↗
Study Summary
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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00495300
The ClinicalTrials.gov registry entry for NCT00495300 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 395 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Allergy and Infectious Diseases (NIAID), which has 1,295 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Bone Marrow Transplantation appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00495300 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll. Verify current status, eligibility criteria, and contact details directly at ClinicalTrials.gov, and discuss any participation decision with your own healthcare provider.
