Active clinical trials for "Pulmonary Fibrosis"

The combined pulmonary fibrosis and emphysema syndrome (CPFE) individualized by our group in 2005 is characterized by an often severe dyspnea, almost exclusive male predominance, and often major, profound impairment of gas exchange contrasting with preserved lung volumes and absence of airflow obstruction, and a high risk of pre-capillary pulmonary hypertension responsible for increased mortality. Almost all patients are smokers or ex-smokers. There are some arguments in favor of genetic abnormalities in this syndrome of unknown etiology (other than smoking) including short telomeres and mutations in the telomerase complex genes. There are also emphysematous lesions, in patients with familial pulmonary fibrosis, with mutations in the SFTPC gene (surfactant protein C), and reported cases of CPFE syndrome with SFTPC mutation. No large genetic studies have been conducted to date in the CPFE syndrome. Our main hypothesis is that the proportion of subjects with short telomeres is higher among patients with CPFE syndrome than in subjects of similar age with idiopathic pulmonary fibrosis but without emphysema. It has previously been shown that mutations in the telomerase TERT or TERC genes are mostly found in people whose telomeres are abnormally short. The investigators propose to use that test to identify patients most likely carrying a mutation, and to seek, among them, the mutations in the TERT or TERC telomerase genes. The objective of the study is to compare the proportion of patients with short telomeres in the group of patients with CPFE syndrome to that of other patients (with idiopathic pulmonary fibrosis without emphysema, or with emphysema without fibrosis).

To prospectively study novel blood and lung biomarkers of disease activity in patients with IPF and other interstitial lung disease with the aims of prognostic modelling and disease clustering

As there are no validated tools for assessing patient reported outcomes or health related quality of life in idiopathic pulmonary fibrosis (IPF), different studies have utilised different methods. This means that comparison of the outcomes of studies is difficult or inaccurate. By collecting different quality of life tools and patient reported outcome at the same time, it will be possible to map or model the results of one tool or groups of tools onto another. 250 patients with IPF will be asked to complete the EuroQoL 5D, Kings Brief Interstitial Lung Disease questionnaire, St George's Respiratory Questionnaire, MRC dyspnoea scale, University of California, San Diego shortness of breath questionnaire and the Hospital Anxiety and Depression Scale, along with spirometry every 3 months, and undergo a 6 minute walk test every 6 months, over a 12 month period. Prognostic models will be constructed from all the clinical (questionnaire and function) measures a linear regression model.

The purpose of this study is to use the Medication Adherence Reasons Scale (MAR-Scale) to determine the extent of non-adherence to specific medications indicated to treat cystic fibrosis, hemophilia (A or B), idiopathic pulmonary fibrosis, myasthenia gravis, and sickle cell disease, and to identify the top patient-reported reasons for non-adherence. Internal reliability of the MAR-Scale will also be assessed in each condition.

The investigators are trying to understand the role of specific genes in the function of airway surface cells. The investigators know that there are some common genetic markers that are associated with various lung diseases. However, most people with these genetic markers never develop any evidence of lung disease, so it is not understand how or if these markers play a role in disease. Investigators are asking healthy people to provide three (3) tubes of blood as well as a sample of cells from their nose. Investigators will use the blood sample to provide genetic information (specifically, presence or absence of alleles known to be associated with pulmonary fibrosis). Nose cells from individuals with the genetic markers that investigators are studying will be grown in the the lab to allow investigators to learn more about how the cells respond to various forms of environmental stress, such as exposure to cigarette smoke. The goal of this study is to understand how specific genes affect airway cell function.

The diagnosis of idiopathic pulmonary fibrosis (IPF) is currently one of the most common diagnoses for patients under evaluation for lung transplantation. In recent years, an absolute increase in prevalence/ incidence of IPF has been observed. There is evidence that patients with IPF on waiting list for lung transplantation might benefit from pirfenidone treatment. Until now, no data are published regarding this important issue in lung transplantation. Primary objective is to determine whether there is a difference in the duration time of mechanical ventilation (weaning) directly after lung transplantation between patients treated with pirfenidone and patients without pirfenidone treatment. The Secondary objectives are to determine whether there are differences between the pirfenidone treatment group and the control group regarding survival after LUTX, the score on the Saint Georges Respiratory Questionnaire and the decline in forced vital capacity (FVC%) In this Investigator initiated, non- interventional single center study , patients on the waiting list for transplant pirfenidone treatment receive oral pirfenidone at the standard dose of 2403 mg per day. The treatment duration will range from 6 to 12 months. A control group will be used to correlate the outcome-parameters for a descriptive comparison. The control group includes patients with IPF on the waiting list who were on another IPF specific (or no) treatment for IPF The Study Population are Patients aged between 40-70 years who are admitted to the lung transplantation department and fulfill the international criteria for idiopathic pulmonary fibrosis ( existence of a usual interstitial pneumonia (UIP) pattern in the high-resolution computed tomography (HRCT) is necessary). Variables: Duration of mechanical ventilation after LUTX (hours), Forced Vital capacity relative to reference value at baseline (FVC0%), Forced Vital capacity relative to reference value after 6 months (FVC6%),Forced Vital capacity relative to reference value after 12 months (FVC12%) Study Size: 30 patients in the Pirfenidone group, 20 patients in the control group. For the primary Endpoint, the mean, standard deviation, median, minimum and maximum of the weaning time of patients who received a pirfenidone treatment, as well as of patients from the control group will be computed and presented in a table. Additionally, a Kaplan-Meier curve will be estimated and plotted alongside the respective 95% CI calculated using the method of Brookmeyer and Crowley. Furthermore, a stepwise linear regression using forward selection and Age, RBMI, FVC0%, (FVC6%-FVC0%), TLC, FEV1% and ECMO, as well as the pirfenidone treatment as predictors will be computed. The null hypothesis is that the pirfenidone treatment has no influence on the weaning time. The according model coefficient estimate and standard error will be used to test the null hypothesis using a t-test at significance level α=0.05. For the secondary endpoints, the mean, standard deviation, median, minimum and maximum of patients who received a pirfenidone treatment, as well as of patients from the control group will be computed and presented in a tableStepwise Cox Regression using forward selection and Age, RBMI, FVC0%, (FVC6%-FVC0%) and ECMO, as well as the pirfenidone treatment as predictors will be computed in order to compare the treatment and the control group a . If p-values are calculated for the secondary endpoint analysis, they serve only descriptive purposes. Therefore no multiple testing corrections are applied.

The purpose of this study is to create a database of demographics and samples in idiopathic pulmonary fibrosis.
