Ex Vivo T-Cell Depletion of Mobilized Peripheral Blood Stem Cells Via CD34-Selection
NCT01189786 · View on ClinicalTrials.gov ↗
Study Summary
Participants are being asked to take part in this study because treatment of his or her disease requires a stem cell transplant. Stem cells or "mother" cells are the source of normal blood cells and lead to recovery of blood counts after bone marrow transplantation. Unfortunately, there is not a perfectly matched stem cell donor (like a sister or brother) for the participant and his or her disease does not permit enough time to identify another donor (like someone from a registry list that is not his or her relative) or another suitable donor has not been identified. However, a close relative of the patient has been identified whose stem cells are not a perfect match, but can be used. Alternatively, the patient may have already received a stem cell transplant but have evidence of mixed chimerism, which means some of the patient's own bone marrow cells are present, rather than all of the donor's cells. This may lead to an increased risk of the disease coming back. Or, the patient may have all donor cells but his or her bone marrow is not working very well, which may lead to frequent blood or platelet (cells that help in clotting blood) transfusions or infection. Regardless of the reason, it may be necessary to isolate stem cells from a haploidentical (half-match) donor in order to provide bone marrow function. Because the stem cells from the donor are only half-matched to the participant, the risk of graft-versus-host disease (GvHD) is very high. GvHD is a complication after transplant caused by donor T cells (graft) that attack the transplant recipient, and this complication can cause death after transplant. Thus, it is important that the donor's blood cells are treated to minimize cells that are most likely to attack the host's tissues. This is done by using a special device to capture the CD34+ stem cells from the donor's stem cell product prior to giving the cells to the host. This method minimizes the donor T cells, which are responsible for causing GvHD. Pur

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT01189786
The ClinicalTrials.gov registry entry for NCT01189786 describes a study currently listed as recruiting. It is categorized as NA, 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 241 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Baylor College of Medicine, which has 678 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Stem Cell Transplant appearing as the primary indexed condition, and to 1 intervention — of which CliniMACS CD34 Reagent system 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: NCT01189786 reports 2 study locations spanning 1 distinct geographic area — top geographies include Texas. 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.
