Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

Preliminary evidence suggest that patients with chronic obstructive pulmonary disease (COPD) suffer from lower-limb muscle dysfunction. This may, at least in part, be due to a combination of physical inactivity and muscle oxidative stress. Pilot data (not published) clearly show that patients with COPD have significantly lower carnosine, which is a pH (acidity-basicity level) buffer and antioxidant, levels in the m. vastus lateralis compared to healthy subjects. Beta-alanine supplementation has shown to increase muscle carnosine in trained and untrained healthy subjects. This study will assess if muscle carnosine can be augmented by beta-alanine supplementation in 40 COPD patients (20 patients receive beta-alanine, 20 patients receive placebo). 10 healthy elderly controls will also be assessed to compare baseline muscle carnosine levels. The aims of this study are to: Investigate baseline muscle carnosine levels to confirm the pilot data in a larger sample of patients with COPD compared with healthy elderly subjects Investigate if beta-alanine supplementation augments muscle carnosine in COPD patients and whether it has an influence on exercise capacity, lower-limb muscle function and quality of life To investigate baseline and post supplementation structural and metabolic muscle characteristics and markers of oxidative stress and inflammation in COPD patients and it's association with muscle carnosine levels

To assess the bronchodilation of three doses of formoterol fumarate (6 μg, 12 μg and 24 μg) twice daily (BID) administered via Pressair® compared to placebo and to open-label nebulized formoterol fumarate (20 μg and 40 μg).

The primary objective of this study is to assess the effect of umeclidinium/vilanterol (UMEC/VI) versus tiotropium/olodaterol (TIO/OLO) in subjects with moderated COPD. This is a multicentre, randomized, open label, 2 period crossover complete block design study. Eligible subjects, who complete a 2-week run-in period, will be randomized to receive a sequence consisting of UMEC/VI inhalation powder (62.5/25 microgram [mcg] once-daily [QD]) administered as 1 inhalation via the ELLIPTA® Inhaler and TIO/OLO 5/5 mcg inhalation spray administered as 2 inhalations via the RESPIMAT® inhaler, for 8 weeks each. This will be followed by a 3-week washout period and one-week follow-up period. The total duration of subject participation in the study will be approximately 22 weeks.

The primary objective of the present study is to evaluate the effect of tiotropium + olodaterol fixed dose combination (FDC) compared to tiotropium monotherapy on the intensity of breathlessness during the 3min constant speed shuttle test (CSST). A secondary objective is to explore the relationship between reductions in breathlessness during the 3min CSST and reductions in breathlessness during activities of everyday living as measured by the dyspnea domain of the Chronic Respiratory Questionnaire (CRQ) following bronchodilator therapy.

Chronic obstructive pulmonary disease (COPD) is one of the most common diseases in the world. In a recent study, we showed that administration of levofloxacin is superior to placebo in the treatment of decompensation of COPD; it is accompanied by a substantial reduction in mortality and a significant reduction in the residence time in hospital. In Tunisia, few data are available on the epidemiology of COPD decompensation. The choice of antibiotic to be used in this situation is challenging to the clinician who must choose between traditional antibiotics (cyclins, aminopenicillins, cotrimoxazole...) and new antimicrobial agents. Recently, it has been emphasized the selection of patients for treatment according to the degree of systemic inflammation (C-Reactive Protein). Indeed, there would have a correlation between the tracheobronchial infection and elevated inflammatory markers. As the elevation of these markers is proportional to the intensity of the inflammatory reaction of the body, is based on the kinetics of these biomarkers in antibiotic treatment seems logical. Thus, C-Reactive Protein allowed not only knowing when to start antibiotics, but also through their kinetic, these markers can guide the duration of therapy and shorten the duration of antibiotic therapy: a rate cut would ensure that the antibiotic treatment was adopted. Available guidelines stated that antibiotic treatment should be maintained at an average of 7 to 10 days while some studies showed no clinical inferiority of courses as short as 3 days. Further reduction of the duration of antibiotherapy was even suggested in order to reduce the risk of adverse events and the pressure that drives bacterial resistance. Hence, we conducted this study using an algorithm to comprehensively evaluate the role of CRP-guided antibiotic prescription in optimizing treatment duration in AECOPD.

The primary objective of the study is to assess the safety and tolerability of multiple infusions of andecaliximab (formerly GS-5745) in participants with chronic obstructive pulmonary disease (COPD) as assessed by adverse events (AEs) and laboratory abnormalities.

This is a phase IIa dose-ranging, randomized, double-blind, chronic-dosing (14 Days), three-period, placebo-controlled, multi-center, cross-over study to assess the efficacy and safety of two dose levels of a dual pharmacology molecule with the combined properties of a long-acting muscarinic antagonist (LAMA) and a long-acting beta-agonist (LABA); (AZD2115) delivered by a metered-dose inhaler (MDI) in subjects with moderate to severe chronic obstructive pulmonary disease (COPD).

The effects of a nasal high-flow (NHF) therapy in patients with chronic obstructive hypercapnic respiratory failure are still not sufficiently known yet. The aim of this study is a step-by-step generation of physiological data about gas exchange and respiration under high flow therapy using a nasal cannula with an AIRVO 2 device to provide NHF, leading to an analysis of the effects of high flow on PCO2 levels, exercise capacity, quality of life and gas exchange in a long term home treatment compared to a standard low flow long term oxygen therapy (LOT). Hypothesis: NHF and LOT therapy show differences in measured mean overnight transcutaneous carbon dioxide partial pressure (PCO2) after four weeks of treatment.

Chronic obstructive pulmonary disease (COPD) is a widespread disease that can have a major impact on the lives of individuals. An essential element in the treatment of COPD is rehabilitation of which supervised training is an important part. However, not all individuals with severe COPD can participate in the rehabilitation provided by hospitals and municipal training centres due to distance to the training venues and transportation difficulties. The aim of the feasibility study was to evaluate an individualised home based training and counselling programme via video conference to patients with severe COPD after hospitalization with regard to safety, clinical outcomes, patients' perception, organisational aspects and economic aspects.

Vitamin D has an immunomodulatory role. the aim of the present study is to assess the effect of vitamin D supplementation on exacerbation rate of COPD patient with a vitamin D deficiency.
