COVID-19 IgG Formation in Physicians at ALGH and Their Household Members
NCT04540484 · View on ClinicalTrials.gov ↗
Study Summary
This study is a community hospital-based study that will enhance information being obtained in similar studies taking place in France, Denmark, and China. These studies are designed to assess risk of healthcare workers during outbreaks of Coronavirus 2019 (COVID-19) also known as sudden acute respiratory syndrome-coronavirus-2 (SARS-CoV-2). This will be a prospective, single-center observational study involving human subjects. IgG (Immunoglobulin G) antibody will be tested in the serum of physicians working at Advocate Lutheran General Hospital (ALGH). IgG antibodies are the antibodies that form in response to viral or bacterial infections and typically reflect protection against said infection. To date, there have been no studies confirming that IgG antibody formation confers immunity, but studies are ongoing. Furthermore, data is lacking showing conclusive persistence of (possibly protective) antibodies over time. Attending physicians on the medical staff, fellow physicians, and house staff residents who worked at ALGH from March 1st, 2020 and on, will be eligible for the study. Testing will involve a venipuncture to obtain approximately 3mL of blood to be sent to ACL Laboratories for SARS-CoV-2 IgG testing. For physician subjects, this will be performed on four separate occasions, once at the onset of the study, a second test 3 months after the first test, a third test 6 months from the time of the first test, and a fourth and final test 12 months after the initial test. Two household members (defined below), one-time testing will occur within 2 weeks of the physician subject testing positive. All testing will be performed in a two-week window. All physician subjects will be tested at a centralized site that is only serving these subjects, by appointment. We will be offloading testing for household members to one localized commercial ACL site on the ALGH campus at the Center for Advanced Care. The household member testing will be extended to an additional two-wee

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04540484
The ClinicalTrials.gov registry entry for NCT04540484 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 507 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Wake Forest University Health Sciences, which has 1,061 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 Covid19 appearing as the primary indexed condition, and to 1 intervention — of which Screening 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: NCT04540484 reports 1 study location spanning 1 distinct geographic area — top geographies include Illinois. 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.
