Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

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.

Beta blockers are a type of medication mainly used for heart disease. They are commonly used to treat 'angina' and to prevent heart attacks. Patients with COPD are more likely to suffer from heart disease and so already benefit from this treatment for this reason. In addition to this, new research suggests that there may be further benefit of using beta blockers for COPD, even without also having heart disease. The reason why beta blockers are not widely used in COPD at present is because of their potential to make symptoms of COPD worse by causing the airways to narrow. Beta blockers are the opposite type of medication to 'beta-agonists' such as salbutamol which you may be taking for symptoms of breathlessness or wheezing. Nevertheless beta blockers are still used in COPD where the benefits (for example heart disease) outweigh any risks. Current COPD treatment includes inhaled steroids and long acting beta agonists, often given in a combination inhaler (e.g. Seretide or Symbicort) to treat both airway inflammation and airway narrowing, leading to improvement in symptoms. Another drug commonly used is Tiotropium (Spiriva) which is another type of long acting inhaler medication to help with widening the airways. In this study, we wish to find out if two different types of beta blocker cause different effects on the airways in COPD patients. One type of beta blocker is more 'selective' in acting mainly on the heart, with the other type having more general or 'non-selective' effects on both the heart and lungs. By doing this we will also be able to look at how the beta blockers work alongside the 'usual' inhaler treatment described above.

This study is to assess the pharmacokinetics (PK), safety and tolerability of UMEC (62.5µg and 125µg) and VI (25µg) as monotherapies and combinations in healthy Chinese subjects.

The primary objective is to compare the efficacy of UMEC/VI Inhalation Powder (62.5/25 mcg) once-daily with tiotropium (18 mcg) once-daily over 12 weeks for the treatment of subjects with COPD who have received tiotropium and continue to have symptoms while on tiotropium.

This study will evaluate the pharmacokinetics of FF, UMEC and VI administered from one inhaler (at two different strengths of UMEC (125 and 62.5microgram [mcg]) and FF/VI (ICS/LABA) and UMEC/VI (LAMA/LABA). Subjects will receive each of the four treatments once, separated by a wash-out period of 7-21 days between doses in a four way crossover design. There will be 4 treatment periods in total. During each treatment period, subjects will attend the clinical unit on Day -1 for standard safety assessments in addition to familiarization with the inhaler. Each subject will remain resident in the unit until at least 24 hours after the dose given on Day 1. Following completion of all four treatment periods, a follow up visit will take place 7 to 21 days following the final dose of study medication.

The investigators hypothesize that education will improve exercise capacity, symptoms and quality of life in patients with chronic obstructive pulmonary disease (COPD). In addition, the investigators are interested in determining how education might alter various chemicals in the blood and exhaled breath that reflect inflammation in the lungs and the body as a whole. The investigators plan to enroll 42 patients into this study, with half of them participating at each of the two sites, Vermont Lung Center at the University of Vermont in Burlington, Vermont, and at Baylor College of Medicine in Houston, Texas. Participants will undergo a series of measurements and tests at the beginning of the study, receive formal education about COPD over the next 2 weeks, return at 6 weeks for a brief refresher session, and finally return after 12 weeks for repeat measurement and testing as was done at the beginning. Participants will be asked to keep a diary of symptoms, medication, and exercise during the study.

The objective of the project is to better understand the causes of exercise limitation, dyspnea and neurohumoral activation in patients with COPD. In particular, the investigators aim to explore the mutual interaction of neurohumoral activation and exercise limitation thereby focussing on differential effects of the peripheral muscle and the diaphragm. Eventually the findings might influence treatment modalities. If sympathetic activation contributes to exercise limitation then drugs influencing the autonomic nervous system would be a reasonable therapeutic concept. If a reduction of sympathetic activity due to an alteration of the ergoreflex can be achieved by non-invasive ventilation this would help to improve dyspnea and exercise capacity.

The purpose of this 24 week study is to evaluate the spirometric lung function effect (trough FEV1) of Umeclidinium/Vilanterol 62.5/25 once daily compared to Tiotropium 18 mcg once daily along with safety assessments in subjects with COPD.

This study is the First Time in Human Study for GSK2256294 and will evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of single and repeat oral doses of GSK2256294 administered to healthy male volunteers (Cohort 1) and otherwise healthy adult male moderately obese smokers (Cohorts 2 to 4). Cohorts 1 and 2 will enrol 12 subjects each and each subject will take part in four study periods. All subjects will receive placebo regimen and three dosing regimens of GSK2256294 in a specified sequence (planned doses 2 mg, 6 mg and 18 mg in Cohort 1 and 15 mg, 40 mg and 100 mg in Cohort 2). Each study period will be followed by a Wash-out period of 7 to 14 days in Cohort 1 and up to 4 weeks in Cohort 2. During each study period subjects will be in-house from Day -1 until the 48 hours post dose assessments have been completed. Subjects will return to the unit as out-patients for remaining post-dose assessments. Subjects will then be followed for 7 to 14 days in Cohort 1 and up to 3 to 4 weeks in Cohort 2. Total duration of the study for Cohort 1 will be 98 days and for Cohort 2 it will be up to 144 days. Cohort 3 and 4 will each recruit 15 subjects. For Cohorts 3 and 4, each subject will take part in one treatment period of 18 days (Day-1 to Day 17) with dosing from Day 1 to Day 14. Subjects will then be followed for 7 to 14 days. Total duration of the study for Cohort 3 and Cohort 4 will be 67 days. Dose selection for Cohorts 3 and 4 will be based on the safety, PK profile and enzyme inhibition obtained in Cohorts 1 and 2. This study will also evaluate the evidence for a functional effect of soluble Epoxide Hydrolase (sEH) in a forearm blood flow (FBF) model.

The study purpose is to evaluate the effect of QAB149 NVA237 vs. QAB149 on static lung hyperinflation.
