Active clinical trials for "Pulmonary Emphysema"

This study evaluates the safety of medicine on COPD (Chronic Obstructive Pulmonary Disease). This study will last up to 56 weeks, and subjects will visit the clinic 16 times. Subjects will be given breathing tests, and will record their breathing symptoms daily on diary cards.

Lung volume reduction surgery is effective in improving pulmonary function and quality of life in selected patients with severe emphysema although the morbidity of this surgical procedure is still considerable. Morbidity is mainly addressed to general anesthesia-related adverse effects and surgical trauma deriving from lung resection. Having developed an awake nonresectional lung volume reduction surgery technique, which is performed under sole thoracic epidural anesthesia, we have hypothesized that it could offer satisfactory clinical results and reduced morbidity rate when compared with the conventional surgical procedure.

The purpose of this study is to evaluate the safety of the Biologic Lung Volume Reduction System (BLVR) for patients with advanced emphysema.

Rationale: The published clinical trials investigating the bronchoscopic lung volume reduction, showing important patient-related improvements in efficacy, led to the acknowledgement of the treatment in the GOLD-COPD2017 guidelines. Interaction with pulmonary rehabilitation, impact on patient-reported outcomes, physical activity, and extrapulmonary consequences are all topics to gain more insight in. This importantly, to further develop and optimize this innovative and personalized therapy. Objective: To study in detail the impact and optimal timing of pulmonary rehabilitation (PR) on exercise physiology and patient-reported outcomes and the impact of the bronchoscopic lung volume reduction treatment using endobronchial valves (EBV) on cardiopulmonary function, metabolism and changes in body composition. Study design: This study is a randomized controlled trial with 3 study-arms. Group 1 will first follow a PR program and afterwards undergo the EBV treatment. Group 2 will first undergo the EBV treatment and approximately 8 weeks later will follow a PR program. Group 3 will only undergo the EBV treatment (and can choose to follow a PR program after completing the 6 month FU visit). Study population: The study population exist of patients with severe emphysema who undergo a bronchoscopic lung volume reduction treatment using one-way valves. Intervention: Most patients will undergo a bronchoscopic lung volume reduction treatment using endobronchial valves and a pulmonary rehabilitation program. One group of patient will under a bronchoscopic lung volume reduction treatment using endobronchial valves and can choose whether they also want to follow a pulmonary rehabilitation program afterwards. Main study parameters: The main study parameter is the difference in change in endurance time measured by an endurance cycle test between the EBV treatment group and the bronchoscopic lung volume reduction + rehabilitation group (EBV+PR).

This is a 6 week crossover study in smokers with and without COPD to evaluate whether 2 weeks of dual antiplatelet therapy (aspirin 81mg and clopidogrel 75mg) improves pulmonary perfusion (i.e. blood flow in the lungs measured on a contrast CT scan) compared to placebo.

This is a randomised , placebo controlled, double blind , multicentre, Phase II/III study evaluating the safety and efficacy of Kamada AAT for inhalation in patients with Emphysema caused by Alpha-1 Antitrypsin (AAT) deficiency.

The purpose of this study is to show safety and feasibility to administer patients own mesenchymal stem cells to show signs of repair of emphysematous lung tissue

This study is a continuation of the placebo-controlled study CE1226_4001 (NCT00261833) to evaluate the efficacy and safety of Zemaira® intravenous (i.v). administration in subjects with emphysema due to alpha1-proteinase inhibitor deficiency. The long-term verification of a disease-modifying benefit of Zemaira® on the progression of emphysema will be assessed by volume-adjusted lung density, measured yearly by computed tomography (CT).

This is a multi-center, open-label, non-controlled Pilot Study. Approximately 24 patients will be assigned to one of 3 treatment groups (8 patients each group). Patients in each group will receive 2, 4, and 6 (3 followed by a retreatment of 3) subsegmental treatments, respectively. All patients will receive treatment in a single lung under conscious sedation or general anesthesia. Patients will be followed for 24 weeks after completion of PLVR treatment(s). Upon completion of 12-week follow-up, all safety and efficacy data will be analyzed to determine an effective treatment dose. Thereafter, Group 1 patients may elect to be retreated at additional sites so that their total dose received is consistent with the effective dose. All study patients will receive standard medical therapy in addition to PLVR.

This trial is for men and women between the ages of 40 and 74 who have a confirmed diagnosis of emphysema. The objective of the trial is to determine the safety and effectiveness of the IBV Valve at redirecting airflow from diseased portions of the lung to healthier areas to achieve improvement in disease-related health status.
