Interferon Gamma for Drug Resistant Tuberculosis
A Phase 2 study testing Interferon Gamma in people with Pneumonia and Pulmonary Tuberculosis, run by National Institute of Allergy and Infectious Diseases (NIAID) at 1 site in United States.
Trial 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. Read more about this study

About this study
Official title: Treatment of Multiply Drug Resistant Tuberculosis With Interferon Gamma: A Phase I/II Dose Escalation Trial
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 samples collected more frequently-weekly for the first 3 months or until three consecutive negative samples are obtained and then monthly throughout the course of therapy. Patients with lung infection will also have repeat CT scans at 6 and 12 months while on interferon gamma. In one or two patients on the drug, blood will be drawn frequently following one injection of gamma interferon (just before the injection and again at 0.25, 0.5, 1, 6, 12, 18, 24 and 48 hours after it) to see if a difference in blood levels of the drug can be detected.
Read the detailed description
This is a phase I/II, controlled, open label, dose escalation study to determine the tolerance, toxicity, and clinical effect of the administration of interferon-gamma on the clinical condition and immune function of patients with multiply drug resistant M. tuberculosis infections (MDRTB). The study drug (interferon gamma) will be administered subcutaneously three times a week at three dose levels (0.025 mg/m(2), 0.05 mg/m(2), 0.1 mg/m(2)) for one year in addition to anti-tuberculous medications, as determined by in vitro sensitivities.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Interferon Gamma in people with Pneumonia and Pulmonary Tuberculosis, run by National Institute of Allergy and Infectious Diseases (NIAID) at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 0 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 4 Mar 2008. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00001407, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Mar 2008.
