Active clinical trials for "Bronchitis"

The primary objective of this study is to assess the safety and effectiveness of Human Multigene Methylation Detection Kit (Fluorescent PCR Method) for help diagnose lung cancer by comparing with clinical standard method (includes chest CT examination or pathological examination).

N-acetylcysteine (NAC) is described as having mucolytic and antioxidant properties. It is widely prescribed for patients with chronic obstructive lung disease (COPD), particularly for those who have accompanying symptoms of chronic cough and sputum production. Compared to placebo, high-dose NAC will improve Saint George Respiratory Questionnaire scores in patients with COPD and chronic bronchitis.

Computer simulations are being developed to predict air flow abnormalities in the airways of patients with lung disease. The purpose of this study is to obtain actual gas flow measurements in the lungs of healthy patients and patients with lung disease and use these measurements to validate the computer models.

The purpose of this study is to determine whether the medical device "simeox" is safe in the treatment of respiratory diseases, in comparison with traditional physiotherapy.

The purpose of this study was to evaluate the effect of ION-827359 on forced expiratory volume in 1 second (FEV1) in participants with mild to moderate COPD with CB.

Chronic Obstructive Pulmonary Disease (COPD) is an increasing global health problem, which primarily increases among the female population. The purpose of this study is to perform in-depth clinical and molecular characterizations of early stage COPD patients, as well as healthy never-smoker and at-risk smoking control populations to identify molecularly related subgroups patients, including gender-related sub-phenotypes of COPD.

Identifying the role of antibiotics in the treatment of subjects with a microbiologically documented acute exacerbation of chronic bronchitis (AECB) is the purpose of this clinical trial. The trial has been designed to evaluate the efficacy and safety of faropenem medoxomil versus placebo in the treatment of subjects with microbiologically documented AECB.

Study objectives: to document the clinical efficacy of telithromycin(800 mg per day for 5 days) at Test Of the Cure (TOC)visit (D12-D19), in acute exacerbation of chronic bronchitis. to assess the long-term clinical efficacy of telithromycin by telephone at D25-D35 (V3) to assess the safety of telithromycin

The purpose of this research study is to determine whether analysis of genes in sputum is a useful noninvasive technique for measuring response to drugs in patients with COPD. We propose to use polymerase chain reaction to evaluate gene expression in induced sputum from adult current smokers with moderate COPD, adult former smokers with moderate COPD. This study is designed to determine whether changes in expression of previously-identified inflammatory markers in induced sputum can be detected in response to drug therapy in COPD and to evaluate potential differences in the expression of these markers in adult smokers with and without COPD. Pre- and post-treatment serum will be obtained to facilitate proteomic analysis of therapeutic response as well. Changes in sputum gene expression in response to treatment will be the primary outcome variable in this study. Secondary outcomes will include changes in lung function, as well as changes in induced sputum inflammation. These endpoints will be evaluated before and directly after 6 weeks of randomly-assigned treatment with either salmeterol xinafoate or fluticasone propionate/50mcg salmeterol xinafoate combination DPI bid. Endpoints will be re-evaluated following a 4 week wash-out period.

The purpose of this study is to determine if 1 course of antibiotic treatment with telithromycin is superior to azithromycin in the treatment of lower respiratory tract infections (LRTIs), acute exacerbations of chronic bronchitis (AECBs) and community-acquired pneumonia (CAP) in the community setting.
