Active clinical trials for "Lung Diseases"

Chronic Obstructive Pulmonary Disease (COPD) is a common respiratory disease characterized by airflow limitation that is progressive and not fully reversible. Expiratory flow limitation (EFL) is the main mechanism leading to dynamic pulmonary hyperinflation (DPH) and intrinsic positive end-expiratory pressure (PEEPi). DPH and PEEPi lead to increased inspiratory muscle efforts and impaired central drive mechanical and ventilation coupling, which is an important mechanism of dyspnea. Appropriate setting of extrinsic PEEP (PEEPe) can decrease inspiratory efforts and work of breathing, improve patient-ventilator synchrony in severe COPD patients with PEEPi and treated with mechanical ventilation. Nevertheless, the effects of CPAP/PEEPe level on respiratory mechanics, especially on central drive mechanical and ventilation coupling, still need further investigations. In the present study, about 40 patients with COPD will be recruited as research subjects. And the investigators aim to observe the changes in respiratory mechanics, central drive mechanics, central drive mechanical and ventilation coupling at different levels of CPAP. Contrast analysis will be conducted to evaluate the effects of CPAP level on respiratory mechanics and central drive during DPH, which may provide a reasonable basis for the clinical application of CPAP to COPD patients and the exploration of a new reasonable CPAP setting method.

The main aim of this project is to establish whether ambulatory oxygen in patients with fibrotic ILD whose oxygen saturation falls ≤ 88% on a 6MWT, leads to a significant improvement in health status. The core of the project will be a four week randomised, crossover controlled trial of ambulatory oxygen used during daily activities. The optimal Oxygen flow rate is determined by titration at screening visit and administered during activity for a two-week period, compared to two weeks off oxygen.

This is a multicenter, randomized, double-blind, placebo-controlled, 2-period, complete block design cross-over study. The purpose of this study is to evaluate the effect of UMEC/VI 62.5/25 microgram (mcg) on EET as measured by the Endurance Shuttle Walk Test (ESWT) compared to placebo. Additionally, the effect of UMEC/VI compared to placebo on lung function and lung volumes in COPD patients will be characterized. Approximately 298 participants will be screened and, assuming 35% of these will not be eligible for randomization; approximately 194 participants will be randomized. Eligible participants will be randomized 1:1 to one of 2 treatment sequences. In sequence 1 participants will receive UMEC/VI 62.5/25 mcg in Treatment Period 1 and placebo in Treatment Period 2. In sequence 2 participants will receive placebo in Treatment Period 1 and UMEC/VI 62.5/25 mcg in Treatment Period 2. Treatments will be delivered once-daily via a dry powder inhaler (DPI). Each treatment period will be for 12 weeks and will be separated by a wash out period of 12-17 days. The total duration of patient participation, including the Follow-Up will be approximately 30 weeks. All participants will be provided with albuterol for use on an "as needed (prn)" basis throughout the run-in, washout and study treatment periods while on investigational product.

The purpose of this study was to determine whether a fixed dose combination of indacaterol and glycopyrronium (QVA149) has an impact on night-time blood oxygen levels in Chronic Obstructive Pulmonary Disease.

The objective of this exploratory study is to examine the utility of high resolution computed tomography (HRCT) to measure changes in functional pulmonary imaging parameters as a function of short term a) iNO administration and b) nitric oxide (NO) cylinder concentration using the investigational medical device INOpulse® DS-C in subjects with WHO Group 3 PH associated with COPD on LTOT (Part 1) and in Subjects with WHO Group 3 PH associated with Idiopathic Pulmonary Fibrosis (IPF) on LTOT (Part 2 and Part 3)

Study to investigate the effect of 12-week treatment with three doses (5, 25 and 75 mg) BIIL 284 BS on exercise endurance, lung function, quality of life, spontaneous sputum and safety in patients with chronic obstructive pulmonary disease (COPD)

Study to establish the lung function effects of added formoterol (12μg QD and BID) during 2-week periods to pharmacodynamic steady state of tiotropium(18μg QD)

The primary objective of this trial was to establish non-inferiority of lung function response to tiotropium 10 μg, formulated as inhalation powder in the polyethylene hard capsule and delivered via the HandiHaler® 2, compared to tiotropium 18 μg, formulated as inhalation powder in the hard gelatine capsule and delivered via the HandiHaler® (Spiriva®) following single dose inhalation in patients with COPD. A hard polyethylene (PE) capsule with half the strength (tiotropium 5 μg) was included to investigate a dose ordering effect. The secondary objectives were to characterize the pharmacokinetics of tiotropium inhalation powder hard PE capsule (delivered via HandiHaler® 2) and tiotropium inhalation powder hard gelatine capsule (delivered via HandiHaler®) and to compare the safety of the two pharmaceutical formulations.

This is a 12-week, multicentre, randomized, open-label, 2-arm, parallel-group study designed to compare the efficacy and safety of umeclidinium inhalation powder (62.5 mcg once daily [QD]) administered via a novel Dry Powder Inhaler (nDPI) with glycopyrronium (44 mcg QD) administered via a Breezhaler® inhaler in subjects with COPD over 12 weeks of treatment. At the end of the run-in period, eligible subjects will be randomized in a 1:1 ratio to receive umeclidinium 62.5 mcg administered via nDPI or glycopyrronium 44 mcg administered via BREEZHALER inhaler. There will be up to 8 clinic visits conducted on an outpatient basis at Pre-Screening (Visit 0), Screening (Visit 1), Randomization at Day 1 (Visit 2), and after Randomization at Day 2 (Visit 3), Day 28 (Visit 4), Day 56 (Visit 5), Day 84 (Visit 6) and Day 85 (Visit 7). The total duration of subject participation in the study will be approximately 15 weeks. The primary endpoint of the study is clinic visit trough FEV1 (forced expiratory volume in one second) on treatment Day 85. All subjects will have spirometry performed at clinic Visits 1 though 7. Trough spirometry will be obtained 23 and 24 hours after the previous day's dose of open-label study medication at Visits 3 to 7. BREEZHALER is a registered trademark of Novartis AG.

The purpose of this study is to look at whether bortezomib, mycophenolate or the combination of both is better to treat scarring of the lung caused by Systemic Sclerosis.
