Nonmyeloablative Peripheral Blood Mobilized Hematopoietic Precursor Cell Transplantation for Sickle Cell Disease and Beta-thalassemia in People With Higher Risk of Transplant Failure
NCT02105766 · View on ClinicalTrials.gov ↗
Study Summary
Background: \- Some sickle cell disease or beta-thalassemia can be cured with transplant. Researchers want to test a variation of transplant that uses low dose radiation and a combination of immunosuppressive drugs. They want to know if it helps a body to better accept donor stem cells. Objectives: \- To see if low dose radiation (300 rads), oral cyclophosphamide, pentostatin, and sirolimus help a body to better accept donor stem cells. Eligibility: \- People 4 and older with beta-thalassemia or sickle cell disease that can be cured with transplant, and their donors. Design: * Participants and donors will be screened with medical history, physical exam, blood test, tissue and blood typing, and bone marrow sampling. They will visit a social worker. * Donors: * may receive an intravenous (IV) tube in their groin vein. * will receive a drug injection daily for 5 or 6 days to move the blood stem cells from the bone marrow into general blood circulation. * will undergo apheresis: an IV is put into a vein in each arm. Blood is taken from one arm, a machine removes the white blood cells that contain blood stem cells, and the rest is returned through the other arm. * Participants: * may undergo red cell exchange procedure. * will remain in the hospital for about 30 days. * will receive a large IV line that can stay in their body from transplant through recovery. * will receive a dose of radiation, and transplant related drugs by mouth or IV. * will receive blood stem cells over 8 hours by IV. * will take neuropsychological tests and may complete questionnaires throughout the transplant process. * must stay near NIH for 4 months. They will visit the outpatient clinic weekly.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT02105766
The ClinicalTrials.gov registry entry for NCT02105766 describes a study currently listed as active not recruiting. It is categorized as Phase 2, 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 56 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 4 conditions, with Sickle Cell Disease appearing as the primary indexed condition, and to 5 interventions — of which Cyclophosphamide 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: NCT02105766 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.
