Active clinical trials for "Bronchitis, Chronic"

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.

This study evaluates the safety of RejuvenAir Cryospray therapy to treat symptomatic chronic bronchitis patients with airflow restrictions.

The purpose of this study is to determine effectiveness, feasibility and safety/tolerance of Respiratory Therapy in hospitalized patients with acute exacerbations of chronic obstructive pulmonary disease.

The main objective of the current trial is to investigate safety, tolerability and pharmacokinetics of BI 113608 in COPD patients with symptoms of chronic bronchitis.

The purpose of this study is to examine whether breathing helium-hyperoxia during exercise in a pulmonary rehabilitation program can improve the exercise tolerance and health related quality of life of patients with Chronic Obstructive Pulmonary Disease (COPD).

This was a randomized multi-center clinical trial to compare the microbiological efficacy, clinical efficacy, and safety of using standard versus biofilm susceptibility testing of P. aeruginosa sputum isolates to guide antibiotic selection for treatment of airway infection in clinically stable patients with CF.

The purpose of this study is to determine the long-term safety of arformoterol over a period of 12 months in subjects with COPD

Primary Objective: The primary objective of the study is to demonstrate the superiority of telithromycin over azithromycin and over cefuroxime axetil in the reduction of Streptococcus pneumoniae (Sp) strains resistant to beta-lactams or macrolides at the Test of Cure (TOC) visit in the sputum of patients with Sp detected at the start of the study (Visit 1). Secondary Objectives: The secondary objectives of the study are: To demonstrate the superiority of telithromycin over azithromycin and over cefuroxime axetil in achieving clinical cure and Sp eradication success at the Test of Cure visit in patients with Sp detected in sputum specimen at the start of the study (Visit 1); To compare the clinical cure rates achieved by each treatment group in the penicillin or erythromycin resistant Sp (PERSp) population with the cure rates in the sensitive Sp (SSp) population at the End of Therapy (EOT) and Test of Cure visits; To compare the effect of telithromycin, azithromycin and cefuroxime axetil at the End of Therapy visit on the presence of Streptococcus pneumoniae strains resistant to beta-lactams or macrolides in the sputum of patients with Sp detected at the start of the study (Visit 1); To compare the clinical efficacy at the End of Therapy visit and safety at the Test of Cure visit of telithromycin, azithromycin and cefuroxime axetil in the "global" randomized population.
