| NCT00000638 ↗ | Preventive Treatment Against Tuberculosis (TB) in Patients With Human Immunodeficiency Virus (HIV) Infection and Confirmed Latent Tuberculous Infection | Completed | Hoechst Marion Roussel | N/A | 1969-12-31 | To evaluate and compare the safety and effectiveness of a one-year course of isoniazid (INH) versus a two-month course of rifampin plus pyrazinamide for the prevention of reactivation tuberculosis in individuals infected with both HIV and latent (inactive) Mycobacterium tuberculosis. Current guidelines from the American Thoracic Society and the Centers for Disease Control recommend 6 to 12 months of INH for PPD (purified protein derivative)-positive individuals. Although the effectiveness of this treatment is not known for HIV-infected individuals, several studies using INH to prevent tuberculosis in presumably normal hosts have shown 60 to 80 percent effectiveness. Problems with this treatment include compliance, adverse reaction, and the possibility of not preventing disease due to tuberculosis organisms being resistant to INH. A two-month preventive treatment plan should help in increasing compliance. In addition, the use of two drugs (rifampin / pyrazinamide) may help overcome problems with drug resistance. If this study shows equal or greater effectiveness of the two-month rifampin / pyrazinamide treatment, it could alter the approach to tuberculosis prevention for both HIV-positive and HIV-negative individuals. |

| NCT00000778 ↗ | A Pilot Study of Methodology to Rapidly Evaluate Drugs for Bactericidal Activity, Tolerance, and Pharmacokinetics in the Treatment of Pulmonary Tuberculosis Using Isoniazid and Levofloxacin | Completed | National Institute of Allergy and Infectious Diseases (NIAID) | Phase 1 | 1969-12-31 | To evaluate the methodology for rapidly determining the early bactericidal activity (EBA), tolerance, and pharmacokinetics of isoniazid and levofloxacin in the treatment of pulmonary tuberculosis (TB). Traditionally, in trials for treatment of TB, a new drug is administered in combination with two or more other antituberculous agents of known effectiveness over a long period of time. In this setting, it is difficult to determine the effect of any single drug or dose level. Development of new agents for the treatment of TB may be accelerated by a methodology in which a new agent could be evaluated for activity by administering it as a single agent over a short time period. This study utilizes a method to measure the amount of bacteria present each day in the lungs. |
| NCT00000959 ↗ | Prophylaxis Against Tuberculosis (TB) in Patients With Human Immunodeficiency Virus (HIV) Infection and Suspected Latent Tuberculous Infection | Completed | National Institute of Allergy and Infectious Diseases (NIAID) | N/A | 1969-12-31 | To evaluate the safety and effectiveness of a 6-month course of isoniazid ( INH ) in the prevention of clinical tuberculosis in anergic (having diminished or absent reactions to specific antigens) HIV-infected persons who are at high risk for tuberculous infection. A substantial number of HIV-infected persons are anergic, and thus do not respond to the only currently available diagnostic tool for tuberculosis infection (that is, the PPD (purified protein derivative) skin test). Many of these anergic persons are, however, infected with Mycobacterium tuberculosis and eventually develop reactivation tuberculosis, causing both individual illness and spread of infection to others in the community. This study examines the possibility of using INH prophylaxis (that is, for prevention) in anergic HIV-infected patients at high risk for tuberculosis as a means of decreasing the sharp rise in the incidence of tuberculosis due to HIV infection. INH is inexpensive and relatively safe, and thus may demonstrate an acceptable risk/benefit ratio as a medication that can be given over a limited period of time to a population suspected of having, but not proved to have, M. tuberculosis infection. If this study shows INH to be safe and effective in this setting, it could have a major effect on public health in this country. |
