18 Clinical Trials for Bronchiectasis
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 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 patients with muco-obstructive disease.
The purpose of this research is to investigate whether a home-based and health coach supported specific breathing and respiratory muscle training program improves the ability to exercise, the function of the lungs and breathing muscles, and general clinical status in people with non-cystic fibrosis bronchiectasis (non-CFB).
The purpose of this research is to study the effect of training the inspiratory muscles (i.e. the muscle that allow you to breath-in) on exercise capacity, quality of life, and short-term clinical outcomes in patients post lung transplant.
This study is being done to study a safe and non-invasive way to diagnose lung rejection and infection.
The study will evaluate the feasibility of using smartphone speakers and microphones to evaluate the caliber of the airways, detect airway obstruction, aid in airway disease diagnosis, and identify disease exacerbations.
The goal of this pilot clinical trial is to compare telehealth and onsite supervised maintenance exercise program for adults with Chronic Lung Disease. The specific aims of the study are: * To compare 8-week supervised maintenance program delivered onsite and via tele-rehab with no maintenance for patients with Chronic Lung Disease following discharge from traditional exercise or physical therapy or onsite outpatient rehabilitation programs on clinical outcomes (dyspnea, exercise capacity, physical function, physical activity, and quality of life) at 8 weeks and 4-months post-intervention. * To compare the differences in dyspnea, exercise capacity, physical function, physical activity, and quality of life between an 8-week maintenance program delivered onsite and via tele-rehab at 8-weeks and 4-months post-intervention in patients with Chronic Lung Disease following discharge from traditional onsite outpatient rehabilitation. Participants in both intervention groups (onsite and tele-rehab) will undergo a baseline onsite assessment followed by an 8-week supervised exercise intervention either onsite or in a telehealth setting. Control group will receive biweekly check in calls, but no active intervention.
This clinical trial is designed to compare the efficacy and safety of Clofazimine Inhalation Suspension versus placebo when added to guideline-based therapy (GBT)
Goal is to physiologically detect unsuspected small airways obstruction in children and adults with treated heterozygous and homozygous cystic fibrosis. Unsuspected refers to normal routine pre bronchodilator spirometry including normal FEV1(L), FVC (L). and FEV1/FVC%. This is a retrospective study.
The COPD Patient-Powered Research Network (COPD PPRN) is a patient research registry with the goal of enrolling 75,000 or more COPD patients and those at risk who are willing to share their heath information over several years and participate in research. The COPD PPRN has built an online platform to allow volunteers to enroll electronically, complete surveys, be contacted about studies they qualify for and become connected to COPD resources. The goal of the registry is to speed research to find better treatments for COPD and ultimately a cure.
This is an omnibus protocol for studying patients with cystic fibrosis. The main purpose of the study is to obtain samples and data collected during standard clinical care for future research to expand knowledge of the natural history, clinical manifestations (phenotypes) and the genetic variants (genotypes) of cystic fibrosis.
