Active clinical trials for "Pulmonary Fibrosis"

This multicenter, randomized, open-label study will assess the safety and efficacy of oral treprostinil in subjects diagnosed with pulmonary hypertension associated with pulmonary fibrosis.

The purpose of this study is to assess the efficacy and safety of the study drug, known as "ATG Fresenius S," which is sometimes called "EZ-2053," to prevent a lung transplant patient's body from rejecting a transplanted lung or lungs.

The infection of COVID-19 has caused serious threat to the life and health of all mankind and increased huge economic burden. According to the current statistics, the incidence of pulmonary fibrosis after COVID-19 infection is about 27.7% -87%, 81% of severe patients and 37% of moderate patients have residual lung lesions, and 53% of patients still have residual lung abnormalities one year after infection, resulting in restrictive pulmonary dysfunction and affecting the health and life of patients. Therefore, it is very important to study the diagnostic and prognostic markers of pulmonary fibrosis after infection of COVID-19. At present, relevant studies have been carried out on imagomics and serum proteomics of pulmonary fibrosis after COVID-19 infection, and serum biomarkers and imagomics marker models for diagnosing pulmonary fibrosis after COVID-19 pneumonia have been developed. However, there are few studies combining imageomics and serum proteomics, and the mechanism of pulmonary fibrosis after COVID-19 has not been fully clarified. In this study, it is planned to recruit patients with moderate, severe and critical COVID-19 pneumonia infection, collect venous blood from subjects, and perform chest HRCT follow-up. Blood samples were screened by proteomics and verified by expanded samples to screen diagnostic and prognostic markers of pulmonary fibrosis after COVID-19 infection. At the same time, based on deep learning technology, a model was developed to predict the occurrence and prognosis of pulmonary fibrosis after infection of COVID-19 combined with clinical characteristics, serum markers and AI imagomics, so as to provide ideas for further elucidating the mechanism of occurrence and development of pulmonary fibrosis after infection of COVID-19.

The overall purpose of this project is to develop and validate a simple, non-invasive method to detect aspiration of gastro-intestinal fluid into the respiratory tract. In the inpatient setting, the investigators will compare the quantity of cromolyn detected in urine collected overnight after 4 ingestions (at 2h intervals) of a 200 mL of a 1mg/mL solution of cromolyn sodium, by 5 healthy control subjects and 5 patients (3-6 with pulmonary fibrosis; and 3-6 either awaiting or recently undergone lung transplantation) with clinical and laboratory evidence of GER (gastroesophageal reflux) with microaspiration. In the outpatient setting, the investigators will compare the quantity of cromolyn detected in urine collected overnight after 1 ingestions (at 4h intervals) of a 200 mL of a 1mg/mL solution of cromolyn sodium, by 10 patients (3-6 with pulmonary fibrosis; and 3-6 either awaiting or recently undergone lung transplantation) with clinical and laboratory evidence of GER (gastroesophageal reflux) with microaspiration.

Pulmonary Arterial Hypertension (PAH) in the setting of Idiopathic Pulmonary Fibrosis(IPF)is a risk factor for morbidity and mortality in the peri-lung transplant(LT) setting. Currently there is no significant data to support the use of pulmonary vasodilators for PAH in the setting of interstitial lung disease such as IPF. The majority of IPF patients have PAH either at rest or during exercise. The study hypothesis is that sildenafil may improve morbidity and mortality in the peri-LT setting in both IPF cohorts with either resting or exercise PAH.

Taking part in clinical trials usually favors a particular demographic group. But there is limited research available to explain what research attributes affect the completion of these specific demographic groups. This study will admit a wide range of data on the clinical trial experience of pulmonary fibrosis patients to determine which factors prevail in limiting a patient's ability to join or finish a trial. It will also try to analyze data from the perspective of different demographic groups to check for recurring trends which might yield insights for the sake of future pulmonary fibrosis patients.

This study capitalizes on the emerging technology of 19F MRI, using conventional 'thermally' polarized perfluorinated gas (perfluoropropane, or PFP) mixed with oxygen and studied with magnetic resonance imaging (MRI) to visualize ventilation. This technique has not been studied in children. Children and adolescents (6-17 years old) with cystic fibrosis (CF) who have normal spirometry will undergo 19F MRI with the inhalation of an inert contrast gas to study ventilation. Comparisons will be made to a cohort of healthy children (6-17 years old) who will perform the same measures. The primary outcome measure is the feasibility of conducting these studies in the pediatric population. Parallel performance of multiple breath nitrogen washout (MBW) and spirometry will be used to compare the sensitivity of these outcomes to the presence of mild lung disease in these children. Finally, the investigators will compare data obtained during standard breath holds with a novel "free-breathing" technique that will eliminate the need for breath holds during MRI acquisition.

Pulmonary Arterial Hypertension (PAH) in the setting of Idiopathic Pulmonary Fibrosis(IPF)is a risk factor for morbidity and mortality in the peri-lung transplant(LT) setting. Currently there is no significant data to support the use of pulmonary vasodilators for PAH in the setting of interstitial lung disease such as IPF. The majority of IPF patients have PAH either at rest or during exercise. The study hypothesis is that bosentan may improve morbidity and mortality in the peri-LT setting in both IPF cohorts with either resting or exercise PAH.

The goal of this observational study is to learn about risk of progressive pulmonary fibrosis (PPF). The main questions it aims to answer are: Risk factors of PPF Prevalence of PPF Mortality of PPF Patients with interstitial lung disease (ILD) of known or unknown etiology other than IPF who has radiological evidence of pulmonary fibrosis will enroll in this study. All participants will have baseline investigations at the first visit having provided informed consent. At the first visit, baseline characteristics will be collected including demographics, medical history, smoking history, complications and medication use. 50 mL of blood will be obtained. High resolution computed tomography (HRCT), full lung function tests and a 6 min walk test will be performed. Further visits at 6 months and 12 months will include further 50 mL blood sampling. HRCT, full lung function tests and a 6 min walk test will be repeated.

The Londrina Activities of Daily Living Protocol was first developed for Chronic Obstructive Pulmonary Disease patients and was found to be valid and reliable, but there is no validity and reliability study of the Londrina Activities of Daily Living Protocol in IPF patients. The purpose of the study is to Examine the Validity and Reliability of the Londrina Activities of Daily Living Protocol in Idiopathic Pulmonary Fibrosis (IPF) patients.
