Active clinical trials for "Lung Diseases"

The purpose of this research study is to determine the effect of the environment on six-minute walk test performance in individuals with chronic obstructive pulmonary disease due to alpha-1 antitrypsin deficiency. The aim of the study is to determine the environmental impact on physical performance in this population to determine if any factors influence quality of life. This study was developed to evaluate the efficacy of the using the indoor six-minute walk test to determine eligibility for ambulatory oxygen therapy.

The purpose of this study is to measure the effectiveness and safety of TD 4208, an investigational drug being developed to treat people with moderate to very severe COPD, compared to placebo, a treatment without activity.

Dyspnea is the most reported symptom of patients with advanced Chronic Obstructive Pulmonary Disease (COPD) and is undertreated. Morphine is an effective treatment for dyspnea and is recommended in clinical practice guidelines, but questions concerning benefits and concerns about respiratory adverse effects remain. For example, the effect on health-related quality of life and functional capacity is unknown. In one-third of the patients oral sustained release morphine (morphine SR) doesn't relieve dyspnea and it remains unknown whether severity and descriptors of breathlessness may predict a response to morphine. Finally, cost-effectiveness of morphine SR in this patient group is unknown. Therefore, prescription of morphine to patients with COPD is limited. Objectives of this double blind randomized controlled trial are to study the effect of oral administration of morphine SR on health-related quality of life, respiratory adverse effects, and functional capacity; to explore whether description and severity of breathlessness are related with a clinically relevant response to morphine and to analyse the cost-effectiveness of morphine SR. The study population will consist of 124 clinically stable outpatients with COPD and severe dyspnea despite optimal pharmacological and non-pharmacological treatment.

This is a multiple dose, randomized, parallel, double-blind, double-dummy, multicenter and multinational Phase III study to determine the efficacy and safety of Aclidinium bromide 400μg/Formoterol Fumarate (AB/FF) 12 μg compared to individual components and TIO (Tiotropium) 18 μg when administered to patients with stable chronic obstructive pulmonary disease (COPD).

Interstitial lung diseases (ILD) are a group of diseases affecting the lung interstitium. The lung scarring that occurs in ILD is often irreversible with only mitigating therapy available so far. This study intends to carry out an open, single-armed, phase I/II clinical trial to investigate whether lung stem cells can regenerate damaged lung tissue. During the treatment, lung stem cells will be isolated from patients' own bronchi and expanded in vitro. After careful characterization, cultured cells will be injected directly into the lesion by fiberoptic bronchoscopy. The safety and efficacy of the treatment will be monitored by measuring the key clinical indicators.

The aim of the study is to investigate the effect of tiotropium from different devices on a panel of small (IOS, MBNW, DLCO, FVC) and large airway (FEV1, PEF) responses in patients with mild-moderate COPD. Comparisons will be made between Tiotropium Handihaler 18 micrograms once daily and Tiotropium Respimat 5 micrograms once daily

Batefenterol (BAT) is a novel bifunctional molecule that combines muscarinic antagonism and beta2-agonism in a single molecule and is in development for the treatment of chronic obstructive pulmonary disease (COPD). FF is a corticosteroid approved as the inhaled corticosteroid (ICS) component of a combination product, with vilanterol (VI), a long-acting beta2-agonist for COPD. In the current study FF will be investigated as an inhaled product in combination with BAT, for treatment of COPD. This study is an open-label, six-way crossover, single and repeat dose study to evaluate the systemic pharmacokinetics, safety and tolerability of FF and BAT when administered via the ELLIPTA™ alone, in combination, or concurrently at 3 times the clinical dose, following a single dose, and at the proposed clinical dose, following repeat doses. This study will consist of screening period, 6 treatment periods, and a follow-up visit. Each subject will have 3 periods in which they receive a single dose treatment regimen (3 inhalations on Day 1 of each single dose study period) and 3 periods in which they receive a single dose treatment regimen followed by a 7-day, once-daily, repeated dose. On Day 1 of those periods, subjects will receive their single dose as 3 inhalations. On Days 2-8, subjects will receive 1 inhalation per day for the repeated dose regimen. There will be a minimum of 7-day washout between each treatment periods. All subjects will receive 9 treatments and follow-up procedures will be done 7 14 days after the last dose. Forty eight healthy subjects will be enrolled into the study, such that approximately 40 subjects complete dosing and PK assessments. The total duration of participation for each subject in this study will be up to 15 weeks. ELLIPTA is a registered trademark of the GlaxoSmithKline [GSK] group of companies.

The purpose of this study is to investigate whether flutiform® is effective and safe in the treatment of chronic obstructive pulmonary disease (COPD).

This is a multi-centered, randomized, placebo-controlled, double-blind, parallel group, trial evaluating 2 doses of mepolizumab against placebo given every 4 weeks through subcutaneous (SC) injection. In severe COPD subjects, sputum eosinophils levels are elevated to similar levels as those seen in severe asthmatics. It is hypothesized that the reduction of eosinophils with mepolizumab in COPD subjects would translate into a reduction of COPD exacerbations. The study will evaluate the efficacy and safety of mepolizumab, in subjects who are at or above the baseline blood eosinophil count of at least 150 cells/microliters who exacerbate despite regular use of maximal tolerated therapy, appropriate for severe COPD subjects, in the 12 months prior to study start. In total, 660 subjects will be randomized in 1:1:1 ratio to receive mepolizumab 300 mg, mepolizumab 100mg, or placebo administered SC. The total duration of subject participation will be approximately 62 weeks, consisting of a 1 to 2 week screening period, 52-week treatment period and 8-week follow-up period.

Background: The efficiency of Neural respiratory drive (NRD)expressed by a ratio of ventilation to the diaphragm electromyogram (EMGdi) decreases in patients with COPD .Improving the neural respiratory drive efficiency of COPD will help to relieve the clinical symptom and make the patients feel comfort.Noninvasive positive pressure ventilation(NPPV)is a good treatment to AECOPD patients.It is unknown the effects of different mode of noninvasive positive pressure ventilation(NPPV) such as proportional assist ventilation (PAV) and pressure-support ventilation (PSV) on the efficiency of Neural drive of AECOPD and which mode benefit the patients more. Objective: To compare the short-term effects of mask pressure support ventilation (PSV) and proportional assist ventilation (PAV) on Neural respiratory drive in recovering patients of AECOPD
