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.\n\nPatients 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:\n\n* Medical history and physical examination, including height and weight measurements, heart rate, breathing rate, blood pressure and temperature\n* Possibly computed tomography (CT) and X-ray of the lungs\n* Sputum sample\n* Pulmonary function studies\n* Blood and urine tests\n\nPatients' 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.\n\nAt the baseline visit, the patient or caretaker will be trained to use a nebulizer (a special breathing device) to take the study medication.", 'detailedDescription': 'Nontuberculous mycobacterial infections due to Mycobacterium avium complex (MAC) are a growing problem among older Americans, especially women. These organisms are relatively resistant to antituberculous medications and frequently persist or recur. In patients with disseminated infections, interferon gamma has been shown to be a critical cytokine in the resistance to and therapy of these infections. Previous experience with injected interferon gamma has been relatively disappointing, with clinical response rates in conventional therapy-refractory patients of about 20%. Aerosol administration of interferon gamma has been shown to rapidly convert sputum smears to negative in multidrug resistant tuberculosis and in one case of MAC infection. However, in these short-term experiments, cultures have remained positive and patients have had clinical relapse. In addition, aerosol administration of interferon gamma has significantly less systemic activation and side effects than does systemic administration. Therefore, we propose to administer interferon gamma by aerosol into the lungs of patients with MAC infection that has persisted despite adequate conventional therapy. This aerosol will be delivered 3 times weekly by the patient. This trial is randomized and double blinded. The period of therapy is 48 weeks and the follow up is another 48 weeks. All patients must be on conventional therapy at the same time and have organisms that are macrolide sensitive. Screening and treatment will be conducted at the NIH Clinical Center as well as multiple collaborative sites. This study should clarify the therapeutic role for aerosolized interferon gamma in the treatment of nontuberculous mycobacterial infections.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'healthyVolunteers': False, 'eligibilityCriteria': "Patients may be enrolled in the study whether or not they are on antimycobacterial treatment for MAC at the time of screening, provided they have bacteriological evidence of active pulmonary MAC infection at screening and provided they meet the following criteria:\n\nMen or women enrolled in the study must be 18 years of age or older.\n\nPatients must have a documented diagnosis of pulmonary MAC disease made in accordance with the ATS Criteria for Diagnosis of Pulmonary MAC Infection.\n\nPatients must have abnormal HRCT findings at the time of screening consistent with pulmonary MAC infection.\n\nPatients with pulmonary MAC disease in whom MAC has been grown only from bronchoalveolar lavage, should undergo sputum induction at Screening and must have a positive Screening AFB smear or a positive Screening culture for MAC.\n\nPatients previously treated for at least 6 months but not currently on therapy for pulmonary MAC disease may enroll regardless of severity of disease if they meet the following criteria:\n\nPatients must have been received at least 6 months of therapy with at least two drugs;\n\nPatients must have persistence or recurrence of radiographic abnormalities consistent with pulmonary MAC disease;\n\nPatients must have a positive sputum AFB smear at Screening (subsequently confirmed by a positive Screening culture for MAC)\n\nOR: A sputum culture at screening positive for MAC\n\nOR: After at least 6 months of antimycobacterial therapy, a sputum culture, positive for MAC within 24 weeks prior to, or at the time of screening.\n\nPatients receiving antimycobacterial therapy for MAC at the time of screening:\n\nMust have completed at least 6 months of treatment with at least two drugs;\n\nMust have a sputum culture positive for MAC within 12 weeks prior to study entry and a positive sputum AFB smear at the time of screening (subsequently confirmed by a positive Screening culture for MAC).\n\nOR: A sputum culture at Screening positive for MAC\n\nOR: Where semi-quantitative culture results are available, at least 1 sputum culture 1 or greater positive for MAC (i.e. greater or equal to 50-100 colonies on solid media) with the previous 12 weeks, persistent or worsening symptoms consistent with MAC pulmonary disease and persistent or worsening radiographic abnormalities.\n\nPatients who have never been previously treated for pulmonary MAC or who have received less than 6 months of treatment must have: evidence of moderate or severe pulmonary MAC involvement defined by the presence of one or more of the following on HRCT at screening: cavitary disease; bronchiectasis with either multilobar or upper lobe infiltrates, or nodular disease; AND\n\nIn addition to cough, at least two of the following symptoms suggestive of clinically significant MAC pulmonary disease: hemoptysis, dyspnea, fatigue, malaise, weight loss, night sweats; AND\n\nPositive sputum AFB smear at Screening (subsequently confirmed by a positive Screening culture for MAC) or a sputum culture positive for MAC within 24 weeks prior to or at the time of screening.\n\nPatients must not have a history of HIV infection or a positive HIV antibody test by Western Blot.\n\nPatients must not have a disseminated or extra-pulmonary MAC infection.\n\nPatients must not have had more than one sputum culture positive for nontuberculous mycobacteria other than MAC within the previous 6 months thought by the Principal Investigator to be causing or contributing to the patient's pulmonary infection.\n\nPatients must not have pre-treatment MAC isolate resistant to macrolide defined by a MIC greater than 8.0 microgram/mL.\n\nPatients must not have active lung cancer, ongoing or previous treatment for lung cancer within the past 2 years, or a lesion suspicious for lung cancer at Screening.
