Filter by:The goal of this pliot study al is to preliminarily evaluate the effectiveness and safety of transbronchial lung volume reduction surgery using the self-devloped endobronchial valves for chronic obstructive pulmonary disease patients with emphysema phenotype . The main questions it aims to answer are: Does self-devloped endobronchial valves improve the lung function、exercise capacity and symptons of participants? What surgery-related adverse events do participants have after transbronchial lung volume reduction surgery using the self-devloped endobronchial valves? Participants will: undergo transbronchial lung volume reduction surgery using the self-devloped endobronchial valves. receive follow-up before surgery (baseline) and 3 days, 4 weeks, 12weeks after surgery.
To compare the efficacy and safety of subsegmental treatment and segmental treatment with InterVapor in patients with severe emphysema
Rationale: Chronic obstructive pulmonary disease (COPD) is characterised by a high prevalence of peripheral muscle dysfunction, which can have significant clinical consequences, including decreased exercise capacity, reduced quality of life, and even a higher mortality rate. Reduction of lung hyperinflation using bronchoscopic lung volume reduction treatment with one-way endobronchial valves (EBV) is a minimally invasive intervention which improves exercise capacity and physical activity in patients with severe emphysema. This positive effect is also related to weight gain and alterations in body composition. The physiologic and structural adaptations of skeletal muscle function after EBV treatment has never been investigated before. Objective: To investigate the physiological and structural adaptations of peripheral muscle function at a cellular level in response to EBV treatment. Study design: A single center, prospective clinical trial with a single-arm pretest-posttest design. Patients with severe emphysema who will receive a bronchoscopic lung volume reduction treatment are asked to undergo additional in-magnet exercise testing and muscle biopsies before and after placement of EBVs. Study population: Patients with severe emphysema who are scheduled to undergo EBV treatment. Main study parameters/endpoints: The difference in quadriceps phosphocreatine concentration (PCr), quadriceps inorganic phosphorus concentration (Pi), and quadriceps pH at rest, during progressive exercise, and recovery rate will be measured by 31P-MRS to assess the physiological effect of EBV treatment on skeletal muscle function and its bioenergetics. Furthermore, we will perform a detailed histological and biochemical analysis of muscle fiber type composition, mitochondrial density, master regulators of muscle oxidative programming, and mitochondrial respiration before and after EBV treatment.
The investigators will implement a patient-centered outcomes tool for participants in lung cancer screening programs that receive clinically important incidental findings relevant to heart, breast and lung health. The study objective is to evaluate participant response and clinical follow-up following implementation of a patient-centered incidental findings communication tool.
Phase 2 open label extension study to evaluate INBRX-101 in adults with AATD emphysema
Prospective, 2-arm, randomised (2:1), multicentre, open-label clinical trial in patients with severe emphysema. The intervention arm will be treated with Bronchoscopic lung volume reduction in severe emphysema using thermoablation.The interventional treatment (bronchoscopic lung volume reduction) is compared with the usual conservative standard therapy (GOLD guidelines).
Some sparse scientific data support the hypothesis that otherwise unexplained emphysema may be associated with FLNA mutation. This prospective, monocentric, cross-sectional study aimed to describe the frequency of emphysema in patients carrying an FLNA mutation. Patients with FLNA mutations who accept the study will benefit from a chest physician's clinical examination, respiratory function tests and a chest scan. The primary endpoint is to describe emphysema's frequency in patients carrying FLNA mutation. The other objectives are to describe emphysema's features in these patients and to describe their lung function abnormalities. The final goal is to confirm the association between unexplained emphysema and FLNA mutation.
This study is designed to prospectively document changes in FEV1 and health-related quality of life 12 months following sequential segmental treatment with InterVapor® in patients with heterogeneous emphysema with upper lobe predominance. For validity of the study, the results will be compared to patients that receive optimal medical therapy.
The purpose of this study is evaluating the safety of endobronchial transplantation of autologous mesenchymal stem cells derived bone marrow in patients with emphysema.
This study will test that hypothesis that endoscopic lung volume reduction therapy performed using emphysematous lung sealant treatment can be improved using smaller doses delivered to more a larger number of treatment sites.
