Active clinical trials for "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).

This was a multicenter, randomized, double-blind, placebo-controlled study of patients with severe, though stable, cystic fibrosis (CF) whose routine treatment included Pulmozyme. Patients were randomized to either continue Pulmozyme or have therapy withdrawn for 2 weeks (placebo group). Patients must have had stable CF symptoms without any change in therapy for 2 weeks prior to enrollment in order to participate.

The main objective of the study is to evaluate the pertinence of initiating screening for advanced hepatic fibrosis after a FIB4 result > 2.67 automatically calculated in the local laboratory and followed by a specialized hepatic evaluation.

The purpose of this study is to evaluate the pathophysiology of nephrogenic fibrosing dermopathy (NFD)/nephrogenic systemic fibrosis (NSF).

This research is being done to find the genes and other factors that are responsible for differences among persons with cystic fibrosis. We are particularly interested in the factors that relate to the development of Cystic Fibrosis Related Diabetes (CFRD).

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.

Elucirem (Gadopiclenol) is a new macrocyclic gadolinium-based contrast agent (GBCA) with high relaxivity indicated for use in adults and children aged 2 years and older for contrast-enhanced magnetic resonance imaging. The product was approved in 2022 by FDA to be used to detect and visualize lesions with abnormal vascularity in the central nervous system (brain, spine and associated tissues) and the body (head and neck, thorax, abdomen, pelvis, and musculoskeletal system). However, given its at least twofold higher relaxivity than other GBCAs, the performance of Elucirem in cardiac MR (CMR) has yet to be demonstrated. The hypothesis for the study: Half dose (0.05mmol/kg) Elucirem is not inferior to double dose (0.2 mmol/kg) Dotarem in the myocardial scar assessment. All participants will be selected from the investigators previous CMR study cohort with double-dose Dotarem T1 mapping and LGE images. Ten participants without scars will be recruited for the Phase I dose evaluation. Five for 0.05 mmol/kg and five for 0.075 mmol/kg. The investigators have identified 15 participants with LGE findings from double-dose Dotarem CMR acquired in the years 2021, 2022, or earlier years. This study was performed in August 2022. The same protocol will be used for single-dose Elucirem.

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.

The purpose of this study is to assess the safety and efficacy of ABT-493/ABT-530 following 12 weeks of treatment in adults with chronic Hepatitis C Virus Infection genotype 1, 2, 4, 5 or 6 infection and compensated cirrhosis.
