Improved Methods of Cell Selection for Bone Marrow Transplant Alternatives
NCT00001529 · View on ClinicalTrials.gov ↗
Study Summary
Bone marrow transplants (BMT) are one form of treatment for disorders of the blood, including leukemia. However, because the procedure is often associated with potentially life-threatening reactions, it is usually reserved for patients with serious illnesses under the age of 60 years old. One serious reaction complicating bone marrow transplants is referred to as graft-versus-host disease (GVHD). GVHD is a potentially fatal incompatibility reaction. The reaction is caused by antigens found on the cells of the patient that are not present on the cells of the donor. The antigens are recognized by transplanted white blood cells (lymphocytes). These lymphocytes begin attacking the recipient s cells and tissues and may lead to death. In order to avoid GVHD, researchers have developed a technique using peripheral blood instead of bone marrow that allows transplantation of stem cells and removal of lymphocytes. Stem cells are the cells responsible for returning blood cell production to normal. Lymphocytes are the white blood cells that can cause GVHD. The technique requires two steps. In the first step blood cells are collected from donors who have received doses of a growth factor. The growth factor (granulocyte colony stimulating factor) is designed to increase the production of donor stem cells. In the second step white blood cell lymphocytes are removed from the collected blood, leaving only the stem cells. The main goal of this study is to develop and improve the method of processing cells that are collected after stimulation with growth factor (G-CSF), by removing the white blood cell lymphocytes which can cause graft-versus-host disease (GVHD) while keeping the stem cells necessary for healthy blood cell building. In addition, researchers are interested in studying whether giving G-CSF has an effect on lymphocyte function, which may influence the immune reactions occurring in bone marrow transplantation.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00001529
The ClinicalTrials.gov registry entry for NCT00001529 describes a study currently listed as recruiting. 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 500 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Heart, Lung, and Blood Institute (NHLBI), which has 381 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 3 conditions, with Graft-Versus-Host Disease appearing as the primary indexed condition, and to 1 intervention — of which G-CSF is the first listed. 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: NCT00001529 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.
