Active clinical trials for "Bronchiectasis"

The primary objective of the trial is to investigate the effect of the use of inhaled colistimethate sodium, administered twice daily via the I-neb for 12 months, compared to placebo in subjects with non-cystic fibrosis bronchiectasis (NCFB) chronically infected with P. aeruginosa on the frequency of pulmonary exacerbations.

Non-cystic fibrosis bronchiectasis is characterized by irreversible dilatation of the medium-sized bronchi as a result of airway injury due to recurrent or chronic inflammation and infection. Bronchiectasis airways are often colonized with bacterial species. Infections of the airways are thought to play an important role in bronchiectasis exacerbation. The non-specific prevention of recurrent airway infections by immunostimulating agents has gained growing scientific interest. OM-85, consisting extracts of eight kinds of bacteria important in respiratory infections, has shown the benefit for significantly reducing the incidence of exacerbations of chronic obstructive pulmonary disease (COPD). The purpose of this study is to investigate the PReventive effect of OM-85 on Bronchiectasis Exacerbation in Chinese patients (iPROBE). This study is designed as a prospective randomised double-blind placebo-controlled multi-centred trial.

Bronchiectasis is a common chronic lung condition where patients have permanent airways damage leading to daily symptoms of cough, sputum production and recurrent respiratory tract infections. Preliminary studies in our research group have found a severe deficiency of the immune system as a rare cause of bronchiectasis (called immunoglobulin G subclass 2 deficiency) and occurs in about 1 in 20 bronchiectasis patients. The pilot work shows that these patients have more chest infections and their lung function deteriorates more rapidly. There are no trials to date to guide doctors to decide whether we should replace this deficiency from donated blood or not. The aim with treatment is to prevent disease progression and avoid the need for long term antibiotics. This trial will help us understand how this treatment works and its acceptability to patients. This study will help us decide whether investigators should pursue future formalised trials in many centres throughout the UK and how investigators should evaluate such a treatment. We are looking to recruit 20 patients to this study 10 of which will receive weekly replacement therapy and the remaining 10 will receive standard care.

The primary objective of the trial is to investigate the effect of the use of inhaled colistimethate sodium, administered twice daily via the I-neb for 12 months, compared to placebo in subjects with non-cystic fibrosis bronchiectasis (NCFB) chronically infected with P. aeruginosa on the frequency of pulmonary exacerbations.

The general aim of this project is to conduct a randomized, double-blind, placebo-controlled clinical trial of azithromycin to determine whether treatment from infancy is safe and will prevent the onset of bronchiectasis. One hundred and thirty infants will be recruited from CF clinics in Australia and New Zealand and treated from 3 months to three years of age. The primary outcome will be the proportion with radiologically-defined bronchiectasis at 3 years of age. Safety and mechanistic evaluations will also be undertaken.

This study is a prospective, multicenter, randomized, double-blind, placebo-controlled study to investigate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and exploratory efficacy of nebulized CSL787 after administrations of single (SAD) ascending doses in healthy subjects and multiple (MAD) ascending doses in subjects with NCFB.

The purpose of this study is to assess the efficacy and safety of the study drug, known as "ATG Fresenius S," which is sometimes called "EZ-2053," to prevent a lung transplant patient's body from rejecting a transplanted lung or lungs.

To comprehensively evaluate the pulmonary rehabilitation (PR) outcomes of patients with chronic respiratory disease (CRD), and to screen biomarkers for predicting different PR outcomes of patients with CRD using metabolomics methods, and to build a prediction model.

The study hypothesis is that dilations of idiopathic bronchi are particularly common in French Polynesia, and that there are arguments in favour of an underlying genetic factor. The study will retrieve retrospective data in the history of bronchial dilation, patients' personal and family history, microbiological and scannographic data, and the latest cardio respiratory checkup.

Chronic obstructive pulmonary disease (COPD) and bronchiectasis are common chronic respiratory diseases in China. COPD is characterized by irreversible lung function decline due to airway inflammation, emphysema and alveolar destruction. Bronchiectasis is characterized by permanent bronchiectasis, its main clinical symptoms are cough, dyspnea, hemoptysis and recurrent respiratory tract infections. The incidence and prevalence of bronchiectasis have assumed continuously grows in global. Airway microbiota, whose alterations play an important role in the occurrence and development of bronchiectasis, form a complex ecosystem interacted with host cells and various biotic and abiotic factors in the microenvironment. Additionally, mounting evidence suggests that the airway microbiome is associated with COPD phenotypes and endotypes, and that dysbiosis contributes to airway inflammation. However, the mechanisms remain poorly understood, owing to limited knowledge of microbial functional properties, metabolic activities and cross-talk with the host immune system. The investigators aim to collect sputum specimen and perform multi-omic analysis on patients with COPD and bronchiectasis in seven clinical centres in China.
