Host Response to Infection and Treatment in Filarial Diseases
NCT00001230 · View on ClinicalTrials.gov ↗
Study Summary
This study will evaluate and treat patients with filarial infections to explore in depth the immunology of the disease, including susceptibility to infection, disease development, and response to treatment. Filarial infections are caused by parasitic worms. The immature worm (larva) is transmitted to a person through a mosquito bite and grows in the human body to 2 to 4 inches in length. Although many of these infections do not produce symptoms, especially in the early stages of infection, others can have serious consequences, including swelling of the limbs or genitalia, allergic-lung problems, skin rash, eye inflammation that can lead to blindness, and heart disease. This protocol does not involve any experimental diagnostic procedures or treatments, and will use only procedures employed in the standard practice of medicine. Persons between 3 and 100 years of age diagnosed with or suspected of infection with Wuchereria bancrofti, Bugia malayi, Onchocerca volvulus, Loa loa, or other parasitic worms may be eligible for this study. Participants will have routine tests to determine the specific type of filarial infection. These may include special tests of the lungs, skin or heart, depending on the type of parasite suspected. Patients with skin reactions may have a "punch biopsy" to examine a small piece of affected skin. For this procedure, an area of skin is numbed with an anesthetic and a small circular area, about 1/3-inch in diameter and 1/2-inch thick, is removed using a sharp cookie cutter-type instrument. Some patients may require bronchoalveolar lavage. For this procedure, the mouth and throat are numbed with lidocaine jelly and spray and, if needed, a sedative is given for comfort. A small plastic tube is placed in a vein to give medications. A pencil-thin tube is then passed through the nose or mouth into the lung airways to examine the airways. Salt water is injected through the bronchoscope into the air passage, acting as a rinse. A sample of the fluid

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00001230
The ClinicalTrials.gov registry entry for NCT00001230 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 500 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Allergy and Infectious Diseases (NIAID), which has 1,295 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 5 conditions, with Helminthiasis appearing as the primary indexed condition, and to 1 intervention — of which Diethylcarbamazine 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: NCT00001230 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.
