Anthrax Vaccine Clinical Trials

Study Summary

This study will examine the recombinant, that is, produced by genetic engineering, protective antigen (rPA) that brings about antibodies to neutralize the anthrax toxin and that could therefore be predicted to offer protection against anthrax. Today, anthrax is rarely encountered in the United States, since the introduction of vaccines for cattle in the 1930s. A human vaccine was licensed in 1970. Vaccination against anthrax has been confined to people at risk, such as wool sorters and some veterinarians. However, the rising prospects of B. anthracis being used as a weapon have led to routine administration of the anthrax vaccine to members of the armed forces. Adults who are in good health may be eligible for this study. The involvement of 300 adults is planned. Participants will have a general physical exam and test for vital signs. There will also be collection of blood for chemistry and hematology; urinalysis; tests for HIV, hepatitis B and C, and liver function; and a pregnancy test, if applicable. On a random basis, patients will receive one of the rPA formulations. Two doses of rPA will be evaluated, 10 microgram ((Micro)g) and 20 (Micro)g. This evaluation aims to establish the safety and most desirable level of dosage. Patients will receive one injection of the vaccine, administered in the left shoulder or left thigh. About 30 minutes later, their temperature will be taken, and the injection site will be inspected. Rare but severe reactions could occur if there is extreme sensitivity to a vaccine. However, such an occurrence is extremely rare following a vaccine, and if there are any dangerous symptoms, they can be effectively treated by medications available to patients while they are at the clinic. If there are no significant abnormal results, patients may return home. About 6 hours later and daily for 7 days, they will take their temperature and examine the injection site. The vaccine may cause temporary discomfort at the site of injection, and partici

What the Registry Record Tells You About NCT00114621

The ClinicalTrials.gov registry entry for NCT00114621 describes a study currently listed as completed. It is categorized as Phase 1, 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 93 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), which has 237 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 Anthrax appearing as the primary indexed condition, and to 4 interventions — of which Anthrax Vaccine 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: NCT00114621 reports 2 study locations spanning 2 distinct geographic areas — top geographies include District of Columbia, 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.
