Collection of Bone Marrow Aspirate From Normal Volunteers
NCT03949647 · View on ClinicalTrials.gov ↗
Study Summary
Background: Bone marrow is the soft material found inside most large bones of the body. Bone marrow produces red blood cells, white blood cells, and platelets that are released into the blood stream. Inside the marrow, these cells start off as young, immature cells called progenitor cells. Researchers want to study these cells in healthy people. Objective: To understand how progenitor cells change with age. Eligibility: Healthy people ages 18 and older Design: Participants will be screened with a questionnaire, a physical exam, and blood tests. Participants will have a bone marrow aspirate. They will be asked to lie on their stomach or side. A local anesthetic will be injected with a small needle under the skin at the site. A needle will then be placed through the skin and into the hip bone. A small amount of the liquid part of the bone marrow will be taken up into the needle. After the needle is removed, a pressure bandage will be placed on the site. Participants will be asked to become a repeat volunteer and have a bone marrow aspirate sample collected once every other year. They will have a physical exam and blood tests before each collection. The cells from the collection will be used for genetic testing and research. Participants will be in the study for as long as they remain healthy and willing to participate. ...

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03949647
The ClinicalTrials.gov registry entry for NCT03949647 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 2,000 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute on Aging (NIA), which has 127 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 Normal Aging 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: NCT03949647 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.
