Active clinical trials for "Idiopathic Pulmonary Fibrosis"

Idiopathic pulmonary fibrosis (IPF) is a condition where scar tissue (called fibrosis) builds up in the lungs. It usually gets worse over time. Fibrosis causes the lungs to become stiff, and reduces the amount of oxygen that the lungs can take up. People with IPF complain of worsening breathlessness, which limits their day to day activities. Lung function tests are breathing tests that measure how well your lungs are working, and are used by doctors to decide whether to start or stop medicines in people with IPF. However, people with IPF tell us that lung function tests require a lot of effort, can make them cough and feel very short of breath. About 1 in 5 people with IPF are unable to perform lung function results accurately. This might unfairly lead to some people with IPF not receiving the right medications or for their medications to be stopped too soon. Impulse oscillometry (iOS) uses sound waves to measure the stiffness of the lung, and has been used successfully in children who are unable to perform normal lung function tests. The overall aim of the research is to see whether changes in iOS measures can give useful information about the lungs in patients with IPF; for example, by judging the overall impact of the disease on the lungs, or predicting future deterioration. We will look at how iOS changes over time in patients with IPF, and to see whether these measurements can tell us about whether IPF is getting worse or predict important health events, such as hospital admission. We will compare change in iOS with changes in other tests used to monitor IPF and with patient reported ratings of change in their condition. This will help decide the amount of iOS change that is noticed and considered meaningful by people with IPF.

This study will test the effectiveness of warfarin in patients with IPF. Approximately 256 patients will be randomized 1:1 to either warfarin or placebo. Patients will return at week 1 for a safety review and every 16 weeks for 48 weeks. The primary endpoint in the study is the time to either death, non-bleeding/non-elective hospitalization, or a drop of greater than 10% in forced vital capacity (FVC) from baseline.

The purpose of this study is to determine whether combination therapy with sildenafil and losartan can improve function and exercise tolerance in patients with idiopathic pulmonary fibrosis.

This study is designed to evaluate the safety, tolerability, pharmacokinetics and efficacy of QAX576 in patients with idiopathic pulmonary fibrosis.

The purpose of this study is to determine whether lozenges containing interferon-alpha can reduce the frequency and severity of coughing in patients with chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF).

Study GIPF-003 is a Phase 3b study designed to define better therapeutic use of IFN-gamma 1b in patients wtih IPF. The study will be conducted primarily in Europe and will enroll 210 patients.

Idiopathic Pulmonary Fibrosis (IPF) is a fibrosing progressive interstitial lung disease with unknown etiology, with a median survival of 3 years since first diagnosis. The typical radiologic pattern of the disease is usual interstitial pneumonia (UIP) defined by basal and peripheral (subpleural) predominance and a typical cystic degeneration of lung parenchyma (honeycombing), interstitial fibrotic thickening and traction bronchiectasis. Despite the recent introduction of two antifibrotic treatments (Pirfenidone and Nintendanib) which proved to be successful in slowing the decline of pulmonary function in patients with IPF, a benefit of these therapies on average survival remains yet to be demonstrated. A significant part of patients affected by IPF die due to progressive worsening of respiratory failure, often accelerated by the insurgence of acute events, like acute exacerbations. Processes leading to the development and progression of IPF are not yet completely understood. We might hypothesize a regenerative deficit in the lungs of subjects affected, due to a dysregulation of repair mechanism in response to repeated damage (inflammatory, mechanics, infectious, chemical) to the alveolar and vascular epithelium. Moreover, mechanism of damage caused by aging in tissues, with a dysfunction in resident stem cell, might contribute to progression. Patients with IPF undergo mechanical alterations of respiratory system due to progressive restrictive deficit caused by reduction in total lung capacity. This functional alteration generates an ineffective and superficial ventilation due to the waste of the majority inspiratory effort spent in ventilating dead anatomical space. When physical effort occurs, the increased ventilatory necessity and the inability to compensate due to functional impairment leads to increased inspiratory effort and subsequent increase in negative intrathoracic pressure. Recent studies have demonstrated how exerting a pressure (for example when the patient is mechanically ventilated) on lung tissue of subjects with IPF and UIP pattern can generate damage due to unfavorable mechanism of mechanotransduction caused by the pathological behavior of fibrotic lung (''squishy ball lung''). Studies investigating inspiratory effort during spontaneous breathing and respiratory failure highlighted how negative values of intrathoracic pressure might induce self induced lung injury. Respiratory effort can be quantified measuring esophageal pressure through a pressure transducer inserted with a nasogastric tube in the inferior third part of the esophagus. Measuring esophageal pressure is a precise and accurate way of quantifying inspiratory effort, however its use in daily clinical practice is limited by invasiveness of the maneuver, high cost and need for specific clinical training. Physiological studies show that nasal pressure measured at the entrance of the nostril might correlate with esophageal pressure and therefore estimate inspiratory effort of the patient in a noninvasive way. The goal of our study is to evaluate the role of respiratory effort during spontaneous breathing as a potential source of mechanical damage (hence favoring disease progression) in subjects with IPF and UIP pattern. The study aims to identify patient with an unfavorable mechanical phenotype defined by the simultaneous presence of UIP pattern and elevated inspiratory effort after physical activity.

The aim of this study is to investigate the effects of the home-based inspiratory muscle training program on lung functions, dyspnea, inspiratory muscle strength, functional capacity and quality of life in patients with idiopathic pulmonary fibrosis. Patients are evaluated before the inspiratory muscle training and after 8 weeks of training.

This clinical study will evaluate the safety and tolerability of combination treatment of nintedanib and pirfenidone in participants with IPF. Eligible participants must have received pirfenidone for at least 16 weeks on a stable dose. Nintedanib will be added on Day 1 of the study as a combination treatment for IPF for 24 weeks.

This study assesses the tolerability of a single dose of gefapixant (AF-219) in participants with idiopathic pulmonary fibrosis (IPF). Six eligible participants will receive a single 150 mg dose of gefapixant and undergo tolerability and PK assessments.
