New Combination NCT01589497 ↗ Essentiality of INH in TB Therapy Completed National Institute of Allergy and Infectious Diseases (NIAID) Phase 2 2015-06-30 Tuberculosis (TB) disease is caused by bacteria that have infected the lung. TB bacteria are very small living agents that are spread by coughing and can be killed by taking TB drugs. To kill these TB bacteria TB patients have to take a combination of four drugs for 2 months and then two drugs for a further 4 months. During the first 2 months patients take rifampicin, isoniazid, ethambutol, and pyrazinamide. After that patients take only isoniazid and rifampicin for a further 4 months, making a total of 6 months therapy. In A5307 the investigators wanted to test a new combination of drugs to see if the investigators could treat TB faster in the future. Studies in animals have suggested that one of the four drugs, isoniazid, only works for a few days and may not be needed after the first two doses of TB treatment to kill the TB bacteria. After that its effects wear off to the point that it may even interfere with the other drugs. The investigators wanted to see if stopping isoniazid early, or using moxifloxacin, a different drug, instead could treat TB faster. This study was the first time that this type of regimen without isoniazid had been tested in humans. If the investigators could show that isoniazid stops working after a few days, the investigators could then try to see if they could possibly make a better tuberculosis treatment in the future.

All Clinical Trials for Pyrazinamide

Trial ID Title Status Sponsor Phase Start Date Summary
NCT00000636 ↗ Prophylaxis Against Tuberculosis (TB) in Patients With Human Immunodeficiency Virus (HIV) Infection and Confirmed Latent Tuberculous Infection Completed National Institute of Allergy and Infectious Diseases (NIAID) N/A 1969-12-31 To evaluate and compare the effectiveness of a 2-month regimen of rifampin and pyrazinamide versus a 1-year course of isoniazid (INH) to prevent the development of tuberculosis in patients who are coinfected with HIV and latent Mycobacterium tuberculosis (MTb). Current guidelines recommend 6 to 12 months of treatment with INH for purified protein derivative (PPD)-positive individuals. Problems with this treatment include compliance, adverse reaction, and the possibility of not preventing disease due to INH-resistant organisms. Studies suggest that two or three months of rifampin and pyrazinamide may be more effective than longer courses of INH. A two-month prevention course should help to increase compliance. In addition, the use of two drugs (rifampin and pyrazinamide) may help overcome problems with drug resistance.
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.
NCT00000638 ↗ Preventive Treatment Against Tuberculosis (TB) in Patients With Human Immunodeficiency Virus (HIV) Infection and Confirmed Latent Tuberculous Infection Completed Lederle Laboratories 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.

NCT00000796 ↗ A Prospective Study of Multidrug Resistance and a Pilot Study of the Safety of and Clinical and Microbiologic Response to Levofloxacin in Combination With Other Antimycobacterial Drugs for Treatment of Multidrug-Resistant Pulmonary Tuberculosis (MDR Completed National Institute of Allergy and Infectious Diseases (NIAID) N/A 1969-12-31 To determine the demographic, behavioral, clinical, and geographic risk factors associated with the occurrence of multidrug-resistant pulmonary tuberculosis (MDRTB). To evaluate the clinical and microbiological responses and overall survival of MDRTB patients who are treated with levofloxacin-containing multiple-drug regimens chosen from a hierarchical list. Per 9/28/94 amendment, to assess whether persistent or recurrent positive sputum cultures of patients who show failure or relapse are due to the same strain or reinfection with a new strain. Among TB patients, there has been an increase in progressive disease due to the emergence of antimycobacterial drug-resistant strains of Mycobacterium tuberculosis. Failure to identify patients at high risk for MDRTB increases the hazard for both treatment failure and development of resistance to additional therapeutic agents. Efforts to improve survival in patients with MDRTB will depend on improved methods of assessing the risk of acquisition of MDRTB and identifying drug susceptibility patterns in a timely fashion.
NCT00000950 ↗ Metabolism of Antituberculosis Drugs in HIV-Infected Persons With Tuberculosis Completed National Institute of Allergy and Infectious Diseases (NIAID) N/A 1969-12-31 The purpose of this study is to determine if a relationship exists between the level of antituberculosis drugs (isoniazid, rifampin, ethambutol, and pyrazinamide) in the blood and the outcome of HIV-positive patients with tuberculosis. This study also evaluates how these drugs are absorbed and metabolized in the body.
NCT00001033 ↗ The Treatment of Tuberculosis in HIV-Infected Patients Completed National Institute of Allergy and Infectious Diseases (NIAID) Phase 3 1969-12-31 PER 5/30/95 AMENDMENT: To compare the combined rate of failure during therapy and relapse after therapy between two durations of intermittent therapy (6 versus 9 months) for the treatment of pulmonary tuberculosis (TB) in HIV-infected patients. To compare toxicity, survival, and development of resistance in these two regimens. ORIGINAL: To compare the efficacy and safety of induction and continuation therapies for the treatment of pulmonary TB in HIV-infected patients who are either from areas with known high rates of resistance to one or more anti-TB drugs or from areas where TB is expected to be susceptible to commonly used anti-TB drugs. PER 5/30/95 AMENDMENT: In HIV-negative patients, intermittent anti-TB therapy has been shown to be as effective as daily therapy, but the optimal duration of therapy in HIV-infected patients has not been established. ORIGINAL: In some areas of the country, resistance to one or more of the drugs commonly used to treat TB has emerged. Thus, the need to test regimens containing a new drug exists. Furthermore, the optimal duration of anti-TB therapy for HIV-infected patients with TB needs to be determined.
