Active clinical trials for "Fibrosis"

Study levels of inflammatory mediators in induced sputum of patients with cystic fibrosis before and after a 4 week course of oral hydroxychloroquine.

The purpose of this study is to determine whether a special yogurt can improve performance on certain tests of intelligence and decrease liver inflammation in patients with cirrhosis.

This study evaluated the clinical response of the efficacy and safety of the combination therapy of peginterferon alfa-2a and ribavirin, compared with an antiviral treatment-free group in CHC patients with compensated LC. Additionally, this study evaluated the dosage reactivity and the pharmacokinetic characteristics of the combination therapy of peginterferon alfa-2a and ribavirin in CHC patients with compensated LC.

The primary efficacy objective of this study is to compare the coefficient of fat absorption (CFA) following oral administration of Aptalis Pharma's (formerly Eurand Pharmaceuticals) pancreatic enzyme product (PEP) capsules and placebo in participants with cystic fibrosis (CF) and exocrine pancreatic insufficiency (EPI).

Medicines that decrease blood pressure in the lungs may help idiopathic pulmonary fibrosis (IPF) patients function better. This study will test whether sildenafil improves the ability to exercise in patients with pulmonary fibrosis of unknown cause.

Objective: To evaluate the efficacy and safety of high doses of both peginterferon-alfa 2a (360 ug per week) plus ribavirin (800 mg b.i.d.) in HIV-infected patients with compensated liver cirrhosis by HCV genotype 1 or 4 without previous virological response(*) to a standard dose treatment of both drugs. (*) Non previous virological response: no decrease of plasma RNA-HCV at least 2 log10 after 12 weeks in treatment or breakthrough viremia while on treatment. Additionally, this study will evaluated the influence of simultaneous peginterferon-alfa 2a and ribavirin plasma concentrations on early viral response (EVR) and sustained viral response (SVR) in these patients. Method: Pilot clinical trial, phase II-III, open labeled multicenter in which patients from several hospitals of the Servicio Andaluz de Salud will be enrolled. The usual clinical and analytical follow up will be performed but additional blood samples will be obtained for determination of interferon and ribavirin plasma levels. The primary end point will be a sustained virologic response (defined as an undetectable serum HCV-RNA after 24 weeks after the cessation of treatment). Likewise, rapid virological response (at 4 weeks of treatment), early virological response (at 12 weeks), and end of treatment response rates will be evaluated as well as their relationships with the plasma interferon an ribavirin concentrations determined by ELISA and HPLC, respectively. The safety and tolerability of the studied medications will be evaluated by means of clinical adverse events, physical examination and laboratory results. The evolution of liver fibrosis will be evaluated comparing the basal and end of treatment results of transient elastometry.

The purpose of this study is to evaluate the safety and tolerability of repeated doses of GS-9411 in healthy volunteers. GS-9411 is a sodium channel inhibitor, that may restore airway hydration and mucociliary clearance in the lung.

This is a phase 2 study of HPN-100 in subjects with hepatic encephalopathy (HE) consisting of an open label safety lead-in (Part A), followed by randomized, double-blind, placebo-controlled treatment (Part B).

High frequency chest wall oscillation (HFCWO) has been shown to increase tracheal mucus clearance compared with a control group. These observations led to the development of The Vest® which is a non-stretchable jacket connected to an air-pulse generator and worn by the patient over the chest wall. The generator rapidly inflates and deflates The Vest®, which gently compresses and releases the chest wall between 5 and 20 times per second. This generates mini-coughs that are said to dislodge mucus from the bronchial walls and to facilitate its movement up the airways. The Vest® has been shown to reduce the viscosity of mucus and this should further enhance mucus clearance. People with cystic fibrosis (CF), admitted to hospital with an acute infective pulmonary exacerbation, should increase the frequency and duration of their airway clearance sessions owing to the increase in quantity and viscosity of purulent bronchial secretions.In the United Kingdom, and in many other countries, the availability of physiotherapists to assist with the recommended number of daily treatments is insufficient to meet patient need. If the use of high frequency chest wall oscillation, in addition to 'usual' self airway clearance techniques, in the early morning and evening was to facilitate recovery from an exacerbation, this would indicate an important place for high frequency chest wall oscillation in the management of people with cystic fibrosis. Hypothesis: The addition of high frequency chest wall oscillation to twice daily supervised physiotherapy is as effective as the addition of self treatment in facilitating recovery from an acute infective pulmonary exacerbation, as measured by improvement in lung function, specifically forced expiratory volume in one second (FEV1).

The purpose of this study was to evaluate the efficacy and safety of ivacaftor in subjects with cystic fibrosis aged 12 years and older who have the G551D mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Ivacaftor is a potent and selective CFTR potentiator of wild-type, G551D, F508del, and R117H forms of human CFTR protein. Potentiators are pharmacological agents that increase the chloride ion transport properties of the channel in the presence of cyclic AMP-dependent protein kinase A (PKA) activation.
