| Trial Type | Trial ID | Title | Status | Sponsor | Phase | Start Date | Summary |
|---|---|---|---|---|---|---|---|
| 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 ETHAMBUTOL HYDROCHLORIDE
| Trial ID | Title | Status | Sponsor | Phase | Start Date | Summary |
|---|---|---|---|---|---|---|
| NCT00000641 ↗ | A Phase II/III Trial of Rifampin, Ciprofloxacin, Clofazimine, Ethambutol, and Amikacin in the Treatment of Disseminated Mycobacterium Avium Infection in HIV-Infected Individuals. | Completed | National Institute of Allergy and Infectious Diseases (NIAID) | Phase 2 | 1969-12-31 | To compare the effectiveness and toxicity of two combination drug treatment programs for the treatment of disseminated Mycobacterium avium infection in HIV seropositive patients. [Per 03/06/92 amendment: to evaluate the efficacy of azithromycin when given in conjunction with either ethambutol or clofazimine as maintenance therapy.] Disseminated M. avium infection is the most common systemic bacterial infection complicating AIDS in the United States. The prognosis of patients with disseminated M. avium is extremely poor, particularly when it follows other opportunistic infections or is associated with anemia. Test tube studies and clinical data indicate that the best treatment program may include clofazimine, ethambutol, a rifamycin derivative, and ciprofloxacin. Test tube and animal studies indicate that amikacin is a bactericidal (bacteria destroying) drug that works better when used with ciprofloxacin. Its role in treatment programs is a key issue because of toxicity and because it must be administered parenterally (by injection or intravenously). |
| 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. |
| NCT00001039 ↗ | Evaluation of Treatment for Mycobacterium Avium Complex (MAC) Infection in HIV-Infected Patients | Completed | National Institute of Allergy and Infectious Diseases (NIAID) | Phase 2 | 1969-12-31 | To assess the feasibility of using culture and staining techniques to quantify tissue Mycobacterium avium Complex (MAC) burden in bone marrow. To correlate and compare changes in MAC bone marrow burden with quantitative MAC blood culture results at baseline and after 4 and 8 weeks of treatment. MAC is easiest to detect in the blood, although doctors generally believe that MAC in blood is just "spill-over" from infection of other parts of the body. Traditionally, studies of potential treatments for MAC focus only on MAC changes in the blood. This study compares MAC changes in blood to those in bone marrow, which is another tissue where MAC is often found. |
| NCT00001047 ↗ | Study of Four Different Treatment Approaches for Patients Who Have Mycobacterium Avium Complex Disease (MAC) Plus AIDS | Completed | National Institute of Allergy and Infectious Diseases (NIAID) | Phase 3 | 1969-12-31 | To compare the safety and efficacy of two doses of clarithromycin in combination with ethambutol and either rifabutin or clofazimine for the treatment of disseminated Mycobacterium avium Complex (MAC) disease in AIDS patients. Recommendations have been issued for AIDS patients with disseminated MAC to be treated with at least two antimycobacterial agents and for every regimen to include a macrolide (clarithromycin or azithromycin). However, the optimal treatment for disseminated MAC remains unknown. |
