Active clinical trials for "Mycobacterium Infections"

The primary objective of this trial is to assess the safety and the relative benefit of rifabutin monotherapy in preventing or delaying the incidence of Mycobacterium avium complex (MAC) bacteremia in AIDS patients with CD4 counts less than or equal to 200, as compared to placebo, and to assess if survival is prolonged in patients who receive rifabutin prophylaxis.

To determine the antimicrobial activity and tolerability of rifapentine alone and in combination therapy in patients with AIDS and disseminated Mycobacterium avium complex (MAC) bacteremia. To determine the pharmacokinetics of rifapentine and its metabolite, 25-desacetyl, alone and in combination therapy. To determine the pharmacokinetics of azithromycin and clarithromycin (and its 14-OH metabolite) in combination therapy.

This study will examine the effectiveness of clofazimine in the prophylaxis of Mycobacterium avium complex infection in HIV infected individuals who are at risk to develop this untreatable opportunistic disease. In the absence of truly effective antiretroviral therapy, a potential mode of treatment of patients with HIV infection is to prevent the development of the life-threatening opportunistic infections. Current studies demonstrate a possible efficacy of clofazimine in the prophylaxis against Pneumocystis carinii pneumonia (PCP), the most common AIDS-defining opportunistic infection. Future studies will examine the potential for prophylaxis against the other opportunistic infections. This proposal hopes to define the role of prophylactic clofazimine in preventing the currently untreatable Mycobacterium avium complex infection. AMENDED: To include prophylaxis for Asymptomatic and ARC.

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).

To compare the efficacy and safety of clarithromycin combined with rifabutin, ethambutol, or both in the treatment of disseminated Mycobacterium avium Complex (MAC) disease in persons with AIDS, including individuals who have or have not received prior MAC prophylaxis. It is believed that effective therapy for MAC disease in patients with AIDS requires combinations of two or more antimycobacterial agents in order to overcome drug resistance and the unfavorable influence of the profound immunosuppression associated with AIDS. Data suggest that clarithromycin may have substantial activity in two- or three-drug combination regimens with clofazimine, rifamycin derivatives, ethambutol, or the 4-quinolones.

The purpose of this study is to assess the safety and immunogenicity of M72/AS01E vaccination in virally suppressed, antiretroviral-treated participants with human immunodeficiency virus infection (HIV).

The proposed study will assess the efficacy, safety and tolerability of once daily dosing of Liposomal-Amikacin for Inhalation (LAI) 590 mg for 12 months plus standard of care (SOC) mycobacterial multi-drug regimen in accordance with the 2007 ATS/ IDSA guidelines, for treatment of mycobacterium abscessus lung disease.

The purpose of this study is to evaluate the efficacy, safety and tolerability of 84 days of daily dosing of 590 mg of LAI versus placebo in patients with treatment refractory NTM lung disease. The first part of the study is the 84-day double-blind phase to evaluate the primary and secondary endpoints.

To determine the safety, tolerance, and efficacy of Tigecycline when given daily to patients with rapidly growing mycobacterial disease (especially M.abscessus).

This study will test the safety and effectiveness of inhaled interferon gamma-1b and oral antibiotics for treating mycobacterium avium complex (MAC) infection of the lungs. Patients 18 years of age or older with MAC infection of the lungs who 1) have been previously treated for MAC, or 2) have moderate or severe lung disease due to MAC that has not been previously treated may be eligible for this study. Participants will be randomly assigned to one of two treatment groups. Group 1 will receive 500 micrograms of interferon gamma-1b 3 times a week for 48 weeks by inhalation. Group 2 will inhale a placebo (inactive substance) according to the same regimen. In addition, all patients will receive standard MAC treatment with three antibiotics-clarithromycin or azithromycin, ethambutol and rifampin or rifabutin-taken by mouth times a week. Patients will come to the clinic for a screening visit, baseline visit, 1 month after beginning treatment, and at 3-month intervals thereafter until the end of the study. During these various visits, they will undergo the following tests and procedures: Medical history and physical examination, including height and weight measurements, heart rate, breathing rate, blood pressure and temperature Possibly computed tomography (CT) and X-ray of the lungs Sputum sample Pulmonary function studies Blood and urine tests Patients' eyes will be examined monthly to check for side effects of ethambutol, and hearing and balance will be tested to check for side effects of clarithromycin or azithromycin. At the baseline visit, the patient or caretaker will be trained to use a nebulizer (a special breathing device) to take the study medication.
