Active clinical trials for "Lung Diseases, Obstructive"

Chronic obstructive pulmonary disease (COPD) is a condition characterized by airway obstruction. Patients with COPD experience significant shortness of breath on exertion. The mechanisms responsible for shortness of breath on exertion are well understood in moderate and severe COPD, but, are poorly understood in mild COPD where symptoms appear disproportionate to the degree of airway obstruction. Mild COPD patients show an exaggerated breathing response to exercise, determined by the breathing response to carbon dioxide production (V̇E/V̇CO2). Recent work suggests that the increased V̇E/V̇CO2 during exercise in mild COPD is secondary to increased deadspace (i.e. lung regions with ventilation but no perfusion) and/or ventilation/perfusion (V̇A/Q) inequality (poor matching of ventilation to perfusion). Researchers have proposed that the increased deadspace or V̇A/Q inequality is secondary to pulmonary vascular dysfunction and hypoperfusion of the pulmonary capillaries. Recently, we have shown that inhaled nitric oxide, a potent dilator of pulmonary vasculature, reduces shortness of breath and V̇E/V̇CO2, and improves exercise capacity in mild COPD. This preliminary finding suggests that pulmonary vascular dysfunction is an important contributor to exercise intolerance in mild COPD. Here, we aim to test whether sildenafil, an oral pulmonary vasodilator, can improve exercise tolerance and shortness of breath in mild COPD.

Subjects who completed either OBERON or TITANIA will be offered the opportunity to consent for this Multicentre, Double-blind, Randomised, Placebo controlled, Parallel Group, Phase 3, extension study to evaluate the safety and efficacy of Tozorakimab in adult participants with symptomatic COPD.

This is a multi-center, randomized, double-blind, placebo-controlled, parallel-group clinical study, which aims to evaluate the efficacy, safety, and PK characteristics of Ensifentrine 3 mg twice daily (BID) for 24 weeks treatment of moderate to severe COPD.

A Phase I/II Randomized, Double Blinded, Placebo Trial to Evaluate the Safety and Potential Efficacy of Intravenous Infusion (IV) of Zofin for the Treatment of Chronic Obstructive Pulmonary Disease (COPD).

Background： Neurally Adjusted Ventilatory Assist (NAVA) mode is a new mode of ventilator, using electronic potential of diaphragm to adjust tidal volume. At the same time, this mode can trigger and cycle-off inspiratory time by high sensitivity of electronic potential of diaphragm, increase patient-ventilator synchrony, reduce sedative drug, improve oxygenation, shorten mechanical ventilation day and reduce the rate of diaphragm atrophy. It can improve survival rate and hospital day of patients. Both the animal and human experiment have the effect of lung and diaphragm protection Effect： The results of this trial are expected to obtain electronic potential of diaphragm in patients with obstructive pulmonary disease. Reviewing the current literature, few related literatures have such data presentation. This trial hopes to evaluate whether the use of NAVA can reduce mechanical ventilation day by analyzing electronic potential of diaphragm in patients with obstructive pulmonary disease. Investigators expect that participants with obstructive pulmonary disease using NAVA mode will have significantly less mechanical ventilation day than using conventional mode

The goal of this clinical trial is to compare the acute bronchodilator effect of the Ipratropium / Levosalbutamol 1.25 mg & 0.5 mg / 2.5 mL fixed dose combination nebuliser solution or Levosalbutamol 1.25 mg / 3 mL nebuliser solution and Ipratropium 500 mcg nebuliser solution in stable moderate-severe-very severe COPD patients.

Chronic obstructive pulmonary disease(COPD) patients could benefit from pulmonary rehabilitation(PR) in better managing of the disease and its symptoms and in avoiding future relapses and hospitalizations. However, due to a large number of drop outs from PR, lack of professionals, and the COVID-19 epidemic, the PR has been underutilized, leading to a need for investigation of updated forms. Music therapy, such as rhythm-guided endurance training, singing training, listening to melody, may be one such potential relevant and motivating rehabilitation activity. The study aims to investigate the effects of home-based PR program with a rhythm-guided endurance walking exercise and singing training on both physiological and psychological aspects. Effects will be investigated in a randomized controlled trial (RCT) with 12-week intervention period.

Chronic obstructive pulmonary disease (COPD) is a burden to health care and economic systems globally, to manage this preventable and treatable disease, different pharmacological and non-pharmacological interventions were shown to be effective. Chronic and progressive dyspnea, cough and sputum production are the characteristic symptoms of COPD. The most commonly encountered symptom in patients with COPD is dyspnea, it is a subjective experience of breathing discomfort . It causes impact on patient's health status, sleep quality, anxiety and depression level. Therefore, skills transfer in self-managing major symptoms are crucial to prevent negative consequences, and as suggested by Global Initiative for Chronic Obstructive Lung Disease (GOLD), managing symptoms and to prevent future risk of exacerbations is important for stable COPD cases. Basic Body Awareness Therapy (BBAT) is a physio-therapeutic intervention directed toward patients' functional movement quality. The development of BBAT was based on the hypothesis of persons' lacking contact with and lacking awareness on their own body, with their inner life, external environment and in the relation to other persons. Thus, it leads to dysfunctional movement, pain and other body functions. BBAT focus on multi-perspective within a person including physical, physiological, psycho-social-cultural and existential perspectives. It directs patients to be "aware", guides patients to have mental contact with their body, monitors internal sensations and external environment, and thus, to enhance the self-regulated behavior and positive emotional state. There are three key components in practicing BBAT, namely balance, free breathing and mental awareness. Evidence shown that the effect of BBAT is significant in improving physical and psycho-social well-being in patients with different physical and mental disorders. Now, there is absence of evidence in applying BBAT in managing cases with respiratory diseases, especially for those with prominent symptoms of dyspnea (for example COPD cases). The objectives of this study are (1) to evaluate individual BBAT as an add-on treatment in patients with COPD, (2) to understand COPD patients' experience through participating in individual Basic Body Awareness Therapy (BBAT).
