This study is open to adults with bronchiectasis. People can participate in this study if they produce sputum and have had flare-ups (also called exacerbations). The purpose of this study is to find out whether a medicine called BI 1291583 helps people with bronchiectasis. Participants are put into 2 groups randomly, which means by chance. One group takes BI 1291583 tablets and the other group takes placebo tablets. A placebo tablet looks like the BI 1291583 tablet but does not contain any medicine. Participants take 1 tablet once a day for up to 1 year and 6 months. Participants are in the study for up to 1 year and 8 months. During this time, participants visit the study site up to 10 times and get about 13 phone calls from the site staff. Participants complete a daily diary on a smartphone about their bronchiectasis symptoms and study doctors regularly check for any changes. The study doctors document when participants experience flare-ups. The number of flare-ups is compared between the participants who receive BI 1291583 and those who receive the placebo. The study doctors also regularly check participants' health and take note of any unwanted effects.
A biomarker cohort study design is proposed to study whether specific airway microbiota alterations are associated with pulmonary Non-tuberculous mycobacteria (NTM) disease. In a cohort of 200 subjects suspected of having pulmonary NTM disease, the investigators will evaluate the airway microbiome using an aliquot of the induced sputum and upper airway samples. Since induced sputum may reflect different regions of the upper/lower airways, the investigators will evaluate the upper and lower airway microbiome in a subgroup (case-control group) of patients using samples obtained through upper airway sampling and bronchoscopy, respectively.
Background: * Bronchiectasis is a disease characterized by airways that are inflamed, abnormally dilated, and chronically infected. Individuals with bronchiectasis have a history of chronic and recurring respiratory infections. Depending on the underlying cause, these infections may involve the entire respiratory tract, resulting in sinus, ear, and lung disease. * Bronchiectasis continues to be a significant problem in developing countries and in specific groups of individuals, particularly in people who have cystic fibrosis. Although treatments are available or under development for bronchiectasis related to cystic fibrosis, many of the disease-specific treatments may not be effective for bronchiectasis not related to cystic fibrosis. Objectives: \- To study the natural history of bronchiectasis to identify inherited and immune factors that may explain why certain individuals have chronic recurring infections. Eligibility: * Individuals 5 years of age and older who have an established diagnosis of bronchiectasis or a history of chronic/recurring respiratory infections. * Direct family members (e.g., parents, siblings, children) of patients in the study may also be asked to participate. Design: * Potential participants will be screened with an initial clinic evaluation and full medical history, as well as a general quality of life and respiratory symptom questionnaire. * The following standard procedures may be done as part of the study: air sampling from the nose; imaging studies, which may include an x-ray or computed tomography (CT), lung function tests; and collection of samples of blood, urine, and sputum (phlegm or mucus). Other tests may be performed as required by the researchers, and will be explained to patients as needed. * Both patients and relatives (if asked to participate) will provide the following samples: blood or buccal (cheek swab) cells for genetic testing, sputum, and urine. * To prevent infections and potential disease progression, patients may receive standard medical care and treatment for bronchiectasis and related infections during this protocol.
This study is a randomized, double-blind, placebo-controlled study designed to assess the efficacy and safety of ensifentrine inhalation suspension (3 mg) delivered twice daily via standard jet nebulizer over at least 24 weeks, compared to placebo, in subjects with non-cystic fibrosis bronchiectasis (NCFBE).
Study participants with non-cystic fibrosis bronchiectasis will be given Trikafta for four weeks. The researchers will monitor clinical endpoints, quality of life, and weight. Additionally, cutaneous punch biopsy material material or blood samples from participants who agree to do this optional test will be collected to test cellular response to Trikafta.
The Investigators propose to study pediatric subjects who are diagnosed with cystic fibrosis (CF) and patients with non-CF bronchiectasis, with the goal of developing markers of CF lung disease severity, progression, and therapy response. The Investigator's central hypothesis is that image-based markers can forecast pathophysiology prior to spirometric changes.
The Bronchiectasis Research Registry is a consolidated database of non-cystic fibrosis (non-CF) Bronchiectasis and Nontuberculosis Mycobacteria (NTM) patients from multiple clinical institutions.
The study will examine how the performance of Oscillating Lung Expansion (OLE) therapy affects the respiratory health of patients with Bronchiectasis (BE). The patient will use the BiWaze Clear system for their airway clearance therapy, instead of their previously prescribed therapy. BiWaze Clear is an FDA-cleared respiratory therapy for assisting patients in loosening and mobilizing secretions as well as treating and preventing atelectasis by providing lung expansion and high-frequency oscillation therapies, combined with aerosol delivery. The patient will perform airway clearance with BiWaze Clear as prescribed. The system uses a disposable breathing circuit, which is a single patient use, disposable circuit. The treatment duration is 6 months . The BiWaze Clear System is indicated for the mobilization of secretions, lung expansion therapy, the treatment and prevention of pulmonary atelectasis and has the ability to provide supplemental oxygen when used with an oxygen supply.
The purpose of this single arm clinical trial is to evaluate the effects of 7% hypertonic saline (HS) delivered by nebulizer on clearance of mucus from the lungs in people with bronchiectasis (dilated airways) not due to cystic fibrosis. Mucociliary clearance (MCC) to measure the rate at which a person's lungs can clear inhaled particles will be assessed at baseline, and after acute (single dose) HS treatment, as well as after two weeks of treatment with HS. The study has two main questions: 1. Evaluate the repeatability MCC measures in people with non-CF bronchiectasis 2. Compare MCC at baseline (before treatment with HS), after a single dose of HS (acute effect of HS), and after two weeks of treatment with HS twice a day (sustained effect of HS). Participants will participate in up to 5 study visits if completing both Aim 1 and Aim 2: 1 screening/enrollment visit, 2 baseline visits (1 baseline visit if only participating in Aim 2), 1 visit during which first dose of HS would be administered and assessed, and 1 visit after 2 weeks of treatment with HS.
This study evaluates the safety, tolerability, and activity of inhaled GDC-6988 in participants with muco-obstructive disease.
