Filter by:The purpose of this study is to evaluate, after 1 week of dosing, the efficacy and safety of PT003 compared with its individual components (PT001 and PT005), placebo and two active comparators to demonstrate superiority of the combination to its components, and to assess the relative contribution of the components compared with placebo, in patients with moderate to very severe COPD.
AZD5069 is a new drug being tested for the possible treatment of people with chronic obstructive pulmonary disease (COPD). This is not the first time that AZD5069 will be administered to humans in clinical trials. We are conducting this study to determine whether AZD5069 is safe and well tolerated by healthy males and females in fed and fasted states. We will compare the way the body handles this drug in the fed and fasted states, in subjects in the age group of 18 to 65 years. We will compare the way the body handles this drug between the age groups of 18 to 65 years and above 65 years. We will also be studying how quickly AZD5069 is absorbed into and cleared by the body.
This study is aiming at evaluating whether low frequency ultrasound spectroscopy is a sensitive tool to detect broncholytic effects in patients with obstructive airway diseases.
COPD patients have a reduced exercise tolerance due to a ventilatory limitation. Several studies have shown altered skeletal muscle function. The investigator will study the physiological response to knee-extensor exercise in COPD patients.
The purpose of this multicenter, dose-ranging study is to compare two Fixed-Dose Combinations of aclidinium bromide and formoterol fumarate with placebo, aclidinium bromide and formoterol fumarate, all administered BID in patients with stable, moderate to severe COPD. Every treatment period is 14-days long and there is a 7-days wash-out period in between them. The trial starts with a run in phase of 10 to 17-days duration and it ends up with a follow up contact 14-days after last treatment dose.
The goal of the study is to look at how genes and certain chemicals in the body are related to depression and chronic obstructive pulmonary disease.
The study will be conducted in a single-center, randomized, single-blinded, placebo-controlled, dose escalation design with two dose groups.Multiple-dose inhalation of Ciprofloxacin inhale 50 and 75 mg or placebo will be administered to 16 Japanese patients with COPD in totalPatients with moderate to severe COPD, stage II or III according to GOLD criteria, will participate in the study.The study will consist of 2 steps as indicated below; starting at Step 1 (50 mg) and escalating doses up to Step 2 (75 mg), after the tolerability of the dose in the previous step is confirmed. In each step, the study will be conducted as multiple dose study with b.i.d. regimen for 10 days (between day 2 and 11) in a randomized, single-blind, placebo-controlled design. In addition, before and after the multiple dose administration, single administration will be conducted in each subject (day 0 and 12).
This 12-week study evaluated the efficacy and safety of indacaterol versus placebo.
The purpose of this study is to determine if an assessment protocol that measures the need for support with smoking cessation and that will be administered by primary health care nurses helps patients with obstructive pulmonary disease (COPD) quit smoking.
Optimal clinical management in early stages of COPD is not established. Tiotropium has been shown to improve exercise tolerance during (CWR) cycle ergometry with GOLD stage II to IV COPD, improvements in constant speed treadmill time in a study of patients who also received pulmonary rehabilitation in a population of patients with predominantly severe and very severe disease (GOLD stages III and IV) and improvements in exertional dyspnea, and Shuttle Walk Test distance in GOLD stage III and IV COPD. However, data are lacking on the benefits of tiotropium on exercise tolerance in a patients with early stages of COPD who are symptomatic. Patients with milder ventilatory limitations (GOLD stages I/II COPD patients) may benefit from maintenance therapy and there is limited data on exercise limitation in patients with early stage COPD who are symptomatic. This study is designed to evaluate the mechanisms of breathlessness and assess physical activity limitation in early stage COPD patients compared to age and gender matched controls and will secondly investigate the effectiveness of treatment with tiotropium in improving dyspnea during exercise and exercise duration as a result of the bronchodilation effects of tiotropium leading to a reduction of dynamic hyperinflation in Early Stage COPD patients.
