Active clinical trials for "Lung Diseases, Obstructive"

This study explores whether patients hospitalized with chronic obstructive pulmonary disease (COPD) exacerbation may have fewer days with prednisolone and with the same treatment effect by controlling the treatment by daily measurements of eosinophils.

This study is an open label, randomized, three-way crossover study to assess the effect of particle size on the PK and safety of single inhaled doses of AZD7594 in healthy subjects (males aged 18 to 55 years [inclusive]). The study will be performed at a single study center.

Chronic Obstructive Pulmonary Disease (COPD) is a common smoking related lung disease. The main symptom in breathlessness. Pulmonary Rehabilitation (PR) - a supervised group exercise and education class - is an effective intervention in COPD to reduce symptoms, improve exercise performance and prevent exacerbations. However some COPD patients are unable to to effectively exercise as they are limited by their breathlessness, despite optimal medical management. By reducing their physical activity to avoid the onset of breathlessness, they become deconditioned and then further attempts at exercise make them more breathless, leading to an inactivity cycle. There is a growing evidence base regarding the use of hand hold fan therapy or air therapy to relieve breathlessness at rest. Limited studies have looked at the use of fan therapy during exercise, and its role on exercise capacity and recovery time, provisional results which indicate it may also be useful during activity. Logically you might expect patients who are less breathless to be able to exercise more, or recover quicker. This study aims to investigate the effects a hand held fan will have on sensation of breathlessness and exercise capacity in patients with COPD. This will involve participants undertaking a standardised field walking test ( 6 minute walk test) with and with out the fan and then comparing the distance covered and how they felt during and after exercise. This will better inform how we structure exercise and advice to these patients in the future to empower patients limited by breathlessness.

The purpose of this study was to assess the effect of CK-2127107 relative to placebo on cycle ergometer exercise tolerance, assessed as change from period baseline in constant work rate (CWR) endurance time, utilizing a breath-by-breath metabolic measurement system with integrated electrocardiogram (ECG). The time to intolerance was assessed by a stopwatch and verified from electronic recordings of the cycle ergometer. This study assessed cardiopulmonary and neuromuscular effects of CK-2127107 relative to placebo; the effect of CK-2127107 on resting spirometry relative to placebo; the safety and tolerability of CK-2127107 as well as the pharmacokinetics of CK-2127107.

Breathlessness is an overwhelming symptom affecting tens of thousands of Australians every day. For many people, it persists even when all the underlying causes have been optimally managed (chronic breathlessness). In these circumstances, it often occurs at rest or with minimal exertion. Evidence from a number of clinical studies suggests that a small, regular dose of morphine helps to reduce safely the sensation of breathlessness. However, it is not well established which patients derive more benefit and what is the net clinical effect of this treatment (weighing benefits and harms). This is a phase III, multi-site, randomised, double-blind, placebo-controlled trial with patients with chronic obstructive pulmonary disease (COPD) and severe chronic breathlessness which will explore several important questions: Are regular, low doses of morphine at four possible doses over 3 weeks more effective than placebo at improving breathlessness? Does increasing the dose in people who already are experiencing some benefit provide even greater reduction in worst breathlessness? Does the medication have any effect on daily activity and quality of life? What are the common or serious side effects of this intervention? Does the benefit from the medication outweigh the side effects it produces? Are there specific characteristics of people who are more likely to receive benefit from extended release morphine? Participants will receive once daily extended release morphine (plus laxative, docusate with senna), or placebo (placebo laxative) in addition to their usual medication for up to 3 weeks at increasing doses. Participants will have a medical interview and physical examination to collect some general health information, and baseline measurements including; daily activity, symptoms, and quality of life. A small amount of blood may be required to check eligibility. Further blood samples may be taken at week 1 and 3 to enable testing on how individuals respond to opioids, further consent will be obtained for these samples. Data on benefits, side effects, and medical care will be collected during comprehensive weekly visits. Participants will also fill out a simple diary twice daily for weeks one to three of the study, and for one day each week during an optional 6 month extension stage. The outcome of this study may enable better management of symptoms and activity in people COPD with medicines that are shown to be effective and safe.

This study was designed to investigate the efficacy and safety of NVA237, a long-acting muscarinic antagonist, in patients with moderate to severe COPD.

The primary purpose of the study is to investigate if Symbicort is more effective than Oxis in increasing forced expiratory volume in one second (FEV1), measured at the clinics, in patients with COPD.

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.

This 12-week study evaluated the efficacy and safety of indacaterol versus placebo.

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).
