Prospective Lung Transplant Database for Genetic Research
NCT00339209 · View on ClinicalTrials.gov ↗
Study Summary
This study will create a database of clinical and biological research for use in future studies, with information obtained from lung transplant recipients. The database will consist of genetic material and clinical outcomes to be used in future genotyping studies, that is, studies regarding the genetic makeup of individuals. Lung transplantation has become an important option for patients with advanced lung disease. More than 10,000 patients have received them to date, and about 1,200 transplant operations are performed worldwide each year. Although short-term survival has continued to improve, the 5-year survival rate is less than 50 percent. Most post transplant deaths are directly or directly caused by chronic lung rejection, a condition of scarring that worsens lung function. Patients evaluated for lung transplants at Duke University Medical Center may be eligible for this study. For developing the database, a small amount of blood, about 3 tablespoons, will be collected from patients. Blood collection for the research will be done at the same time as blood is drawn for necessary tests. The blood cells and DNA (which contains genetic material) will be isolated for analysis. Patients' DNA samples collected will be identified by a code, and all other identifying information will be removed. Patients may be asked to donate additional blood samples after their lung transplant if researchers would like to reexamine their blood. This study will not have a direct benefit for participants. However, during the study, if it is found that any patients have an inherited risk for a disease likely to cause early death if the disease is not treated, then the researchers will attempt to notify those patients. Overall, it is hoped that information gained during this study will help medical professionals to learn more about immune activation and to see how the reactivity of lung transplant patients changes over time. If specific genetic risks could be identified, it might lead

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00339209
The ClinicalTrials.gov registry entry for NCT00339209 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 400 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Environmental Health Sciences (NIEHS), which has 75 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 Lung Transplantation Rejection 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: NCT00339209 reports 2 study locations spanning 1 distinct geographic area — top geographies include North Carolina. 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.
