Active clinical trials for "Lung Diseases"

This is a Phase I, double-blind, placebo-controlled study to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and immunogenicity of a 10 mg/kg dose of AD-214 when administered to healthy volunteers (HVs) (Part A) or patients with interstitial lung disease (ILD) or chronic kidney disease (CKD) (Part B). The study will be performed in Australia at up to two clinical sites.

The goal of this research study is to test the efficacy of a novel immunosuppressive agent, belumosudil, in allogeneic hematopoietic stem cell transplant (HSCT) recipients who have been newly diagnosed or have developing (early stage) bronchiolitis obliterans syndrome (BOS). The name of the study drugs involved in this study are: Belumosudil (an immunotherapy) Fluticasone (an intranasal corticosteroid) Azithromycin (an antibiotic) Montelukast (a leukotriene receptor antagonist) Prednisone (a corticosteroid)

This is a multi-center, prospective study. This study aims to investigate the incidence of acute exacerbation within 12 months, as well as the safety of Staphylococcus and Neisseria Tablets on patients with chronic obstructive pulmonary disease (COPD). In addition, this study investigates the improvement of hospitalization, improvement of pulmonary function, improvement of symptoms, and the use of anti-Infective drugs among COPD patients.

Objectives: To determine whether CRP-guided antibiotic treatment for managing AECOPD in adult patients attending Emergency Departments leads to reduced antibiotic duration, without non-inferior COPD health status with usual care. Hypothesis to be tested: (i) The antibiotic duration in AECOPD patients will be significantly lower for CRP-guided antibiotic discontinuation than usual care; and (ii) COPD health status as measured by the Clinical COPD Questionnaire has no statistically significant difference between two groups. Design and subjects: Multi-center, single-blind, open-label, randomized, combined superiority (antibiotic duration) and non-inferiority (COPD health status) trial in 1,184 adult AECOPD patients presented to A&E. Instruments: Clinical COPD Questionnaire and EuroQol-5D Interventions: Both intervention and control groups follow usual care with GOLD strategy. The intervention group will be recommended to test for serum CRP daily. Antibiotic prescription is considered when CRP >5mg/dL. Once CRP has declined to <5mg/dL and the patient was afebrile for past 48 hours, antibiotic discontinuation will be considered. Communication with Receiving Ward Staffs: Participants in the study may transfer to another departments after treatment/ care in A&E. The following communication would be conducted: A handover note that informs the receiving ward staffs about patients' enrolment to the trial, group assignment, and previous treatments given in A&E. The note would also suggest the investigations for the receiving ward staffs. Telephone handover about intervention group and investigations of the study, and treatments given in A&E to ward. Main outcome measures: The antibiotic duration (total number of antibiotic days) within 28 days and recovery in terms of COPD health status (Clinical COPD Questionnaire total scores) within 14 days from randomisation. Data analysis: Intention-to-treat and cost-effectiveness analyses will be performed. The outcome assessors and data analysts will be blinded to group allocation. Expected results: The intervention group will exhibit reduction in antibiotic duration at 4-weeks, without negatively impacting on COPD health status, compared with the control group.

Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide, resulting in a social and economic burden that is substantial and increasing. Exacerbations affect the prognosis and quality of life of patients with COPD. Hospital mortality of patients admitted for a hypercapnic exacerbation of COPD is approximately 10% and the long-term outcome is poor. In addition, hypercapnic exacerbation of COPD have serious negative impacts on patient quality of life, lung function and costs. Thus, prompt treatment of exacerbations may impact the clinical progression of COPD by ameliorating quality of life and prognosis. Standard of care for patients with COPD exacerbation that need ICU admission for management of acute hypercapnic respiratory failure and severe respiratory acidosis is non-invasive ventilation (NIV). When NIV fails (arterial pH remains < 7.30), invasive ventilation through endotracheal intubation is initiated to restore adequate gas-exchange. Extracorporeal circuits designed to remove CO2 (ECCO2R) may enhance the efficacy of NIV to remove CO2 and avoid the worsening of respiratory acidosis. A recent matched cohort study with historical control, showed that: (a) the hazard of being intubated was three times higher in patients treated with "NIV-only" than in patients treated with "NIV-plus-ECCO2R"; (b) hospital mortality was significantly lower in "NIV plus ECCO2R" than in "NIV-only" [8% (95% CI 1.0-26.0%) vs. 33% (95% CI 18.0-57.5%), respectively]. However, ECCO2R-related complications were observed in almost half of the patients. The consistency of the above discussed data, and the observation of the continuous increase use of ECCO2R despite the lack of solid evidence confirm that the equipoise regarding the use of ECCO2R may justify a randomized clinical trial to evaluate whether patients with respiratory acidosis refractory to NIV should be intubated and take the risks associated with invasive mechanical ventilation, or should be connected to ECCO2R to avoid intubation, but run the risk of the potentially serious ECCO2R-related complication The main objective of this randomized multicenter clinical trial is to test the hypothesis that in patients with acute life-threatening exacerbation of COPD, use of ECCO2R could increase event-free survival as compared to standard of care.

The purpose of this randomized, placebo-controlled double-blind trial is to evaluate efficacy of acetazolamide in preventing overt altitude-related adverse health effects (ARAHE) in lowlanders with chronic obstructive pulmonary disease (COPD) developing early signs of altitude-illness during altitude travel.

As a result of the study, inspiratory muscle strength, posture and physical performance evaluations of individuals with Chronic Obstructive Pulmonary Disease will be made, suggestions will be made to help individual postural smoothness and improve physical performance.

To evaluate the regenerative capacities of mesenchymal cells composing the microenvironment of alveolar type 2 cells in a population of patients, undergoing thoracic surgery for suspected cancer, who are smokers with and without COPD compared to non-smokers patients

The primary intention of this study is to determine the diagnostic performance of ultra-low-dose CT (ULDCT) in diagnosis and follow-up of diffuse parenchymal lung disease (DPLD). We hypothesize that inspiratory and expiratory chest ULDCT has comparable diagnostic yield to standard dose chest High-resolution computed tomography (HRCT) and utility for follow-up of patients with known DPLD. We will study this hypothesis through the following aims: Determine whether inspiratory and expiratory ULDCT are comparable to HRCT in identifying mosaic attenuation due to air-trapping. Determine whether ULDCT is as good as HRCT for follow-up of patients with established DPLD to identify disease progression.

Background: The lung is a privileged organ; blood does not reflect most lung processes well, if at all. Therefore, for population scale diagnostics, the investigator team is developing non-invasive portals to the lung, for eventual early detection/risk assessment and diagnostic purposes. However, large macromolecules are not likely suspended nor readily detected in the breath. In particular, genomic DNA in the breath condensate (EBC) is very sparse, and where present, generally highly fragmented, not readily amenable to sequencing based assessments of DNA somatic mutation burden or distribution. Because gDNA (and protein) is challenging to obtain non-invasively from EBC, the study team considered alternative surrogate lower airway specimens. Cough capture is rarely done, and the investigator team is in the process of optimizing its collection. Importantly, the team will be evaluating how much of coughed material is from saliva contamination. Additionally, analyzing material that is target captured by capturing deep lung extracellular vesicles (EVs) using immobilized CCSP/SFTPC antibodies targeting EVs from distal bronchiole Club and alveolar type 2 cells could circumvent the mouth contamination problem, leaving a non-invasive portal to the deep lung suitable for large molecules, and in turn suitable for myriad epidemiologic and clinical applications. Proposal: The investigator team proposes (Aim 1) to pursue optimizing cough collection, and testing the efficacy and practicality of partitioning cough specimen for deep-lung specific extra-cellular vesicles (EVs). This cough specimen will be compared to that from invasively collected deep lung samples BAL/bronchial brushings, and to the potential contaminating mouthrinse, all from the same individuals. (Aim 2) The study team initially proposes to examine these cough specimens for somatic mutations by SMM bulk sequencing for single nucleotide variation, developed in the Vijg/Maslov labs. Finally, the investigator team will (Aim 3) test all airway specimens (cough, mouthwash and BAL) for lung surrogacy of cough, using proteins known to be specific for lung, as opposed to oral cavity/saliva, in the Sidoli/proteomics core. Impact: The investigator team envisions that the translational impact of non-invasively obtained DNA or protein markers could allow for more rapid acute clinical diagnoses, and facilitate precision prevention and/or early detection of many acute and chronic respiratory disorders, including lung cancer, asthma and COPD, acute and chronic infectious diseases, and indeed systemic disorders of inflammation and metabolism.
