Interferon Gamma for Drug Resistant Tuberculosis
NCT00001407 · View on ClinicalTrials.gov ↗
Study Summary
This study will determine what dose of recombinant interferon-gamma is safe and effective for treating multiple drug-resistant tuberculosis. Recombinant interferon-gamma is a genetically engineered form of a substance normally produced by the body and is used to boost immune function. Patients 5 years of age and older with multiply drug-resistant tuberculosis may be eligible for this study. Participants will be admitted to either the NIH Clinical Center in Bethesda, Maryland, the Texas Center for Infectious Diseases in San Antonio or the South Texas Hospital or Valley Baptist Hospital, both in Harlingen, Texas. On admission, patients will have a medical history, physical examination, blood and urine tests, sputum culture, X-rays, pulmonary function tests and a computed tomography (CT) scan. CT produces 3-dimensional images of body tissues and organs in small sections. For the procedure, the patient lies still on a table surrounded by the scanner. All patients will continue treatment with anti-tuberculosis antibiotics during and after the study period and may elect whether or not to take gamma interferon in addition to the antibiotic. Five patients will receive only antibiotic treatment, and 5 each will receive one of 3 doses (0.025, 0.05 or 0.1 milligrams per square meter of body surface area) of interferon-gamma injected under the skin 3 times a week. The patient or caregiver will be taught to give the injections, which are similar to insulin injections for diabetes. Patients will be in isolation in the hospital from the start of therapy until sputum samples show no evidence of tuberculosis for 3 consecutive weeks. Following that, they will repeat the tests done on admission (except CT) during follow-up visits (1- to 2-day hospitalizations) at 3, 6, 9, 12, 15, 18 and 24 months after the start of therapy. Patients taking interferon gamma will have blood drawn more frequently (monthly) for the first 6 months, and patients with lung infection will have sputum samp

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00001407
The ClinicalTrials.gov registry entry for NCT00001407 describes a study currently listed as completed. It is categorized as Phase 2, 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 30 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 2 conditions, with Pneumonia appearing as the primary indexed condition, and to 1 intervention — of which Interferon Gamma 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: NCT00001407 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.
