Filter by:This is a prospective, longitudinal, 5-year study that will enroll participants from the existing Cystic Fibrosis Foundation (CFF) patient registry. Each enrolled participant will provide samples for microbiological evaluation, obtained upon enrollment and then once per year thereafter for 5 years.
The primary objective of this study is to evaluate the safety and tolerability of subcutaneously (SC) administered multiple, escalating doses of BG00011 (a humanized monoclonal antibody directed against the alpha v beta 6 (αvβ6) integrin, formerly known as STX-100) in participants with IPF. The Secondary objectives are to estimate the pharmacokinetic (PK) parameters after the 1st dose and after the last dose of multiple, escalating doses of BG00011 in participants with IPF, to assess the immunogenicity of BG00011 in participants with IPF, and to assess the effect of BG00011 on biomarkers isolated from bronchoalveolar lavage (BAL) and peripheral blood in participants with IPF.
The purpose of this study is to determine whether early use of transjugular intrahepatic portosystemic shunt (TIPS) with Polytetrafluoroethylene (PTFE) covered stents is able to prolong the survival in patients with advanced cirrhosis and acute variceal bleeding.
PIPF-016 (ASCEND) is a Randomized, Double-Blind, Placebo Controlled, Phase 3 Study of the Efficacy and Safety of Pirfenidone in Patients with Idiopathic Pulmonary Fibrosis. The study objectives are to confirm the treatment effect of pirfenidone compared with placebo on change in percent predicted forced vital capacity (%FVC) in patients with idiopathic pulmonary fibrosis (IPF), and to confirm the safety of treatment with pirfenidone compared with placebo in patients with IPF.
The study consists of 2 parts: Part A is a randomized, multiple-dose, double-blind, placebo-controlled sequential dose escalation study to evaluate GS-6624 in subjects with Idiopathic Pulmonary Fibrosis (IPF) and was completed in October 2011. Part B is a randomized, two-dose, open-label dose expansion study to evaluate GS-6624 in subjects with IPF and is currently enrolling.
Hepatocellular carcinoma (HCC) is one of the tumors with a rising incidence worldwide. The aim of this trial is to improve the detection of early HCC nodules in the liver. At the moment screening for HCC in patients with liver cirrhosis is performed by ultrasound and measurement of alpha- fetoprotein (AFP). In this trail the tumor markers AFP- L3 (a subfraction of AFP) and Des-y- carboxyprothromib (DCP) are measured in addition in order to receive information about the course of these markers before the detection of a HCC nodule.
Cystic fibrosis (CF) lung disease is characterized by chronic bacterial colonization and recurrent infection of the airways. Lowering the airway surface liquid (ASL) salt concentration has been shown to increase activity of salt sensitive antimicrobial peptides. Xylitol is a 5-carbon sugar that can lower the ASL salt concentration, thus enhancing innate immunity.In this study, the investigators plan to study the safety and efficacy of 2 weeks of inhaled xylitol compared to 2 weeks of hypertonic saline in a randomized crossover design in stable subjects with cystic fibrosis
The purpose of this study is to investigate the expression of a certain class of molecules, called costimulatory molecules, in humans with Cystic Fibrosis. Cystic Fibrosis is a genetic disorder which renders the lung susceptible to persistent inflammation which, at times, can worsen, resulting in accelerated decline in lung function and eventually death or transplant. Our goal is to determine if the levels of costimulatory markers can be used to predict exacerbation and subsequent lung function decline in subjects with Cystic Fibrosis.
Purpose: There has been a recent, rapid increase in prevalence of Methicillin-resistant Staphylococcus aureus (MRSA) among patients with Cystic Fibrosis (22% across US CF centers in 2009). Some epidemiologic studies suggest possible worse outcomes, a recent analyses showing this with chronic but not intermittent MRSA. Given the chronic difficult to treat lung infections in CF it is unclear how the onset of MRSA should be approached. This randomized, controlled, interventional study seeks to determine if an early eradication protocol is effective for eradication of MRSA and will provide an opportunity to obtain data regarding early clinical impact of new isolation of MRSA. Participants: Cystic fibrosis patients with new isolation of MRSA from their respiratory culture on a routine clinic visit. Procedures (methods): Randomized, open-label, multi-center study comparing use of an eradication protocol to an observational group who receives the current standard of care i.e. treatment for MRSA only with pulmonary exacerbations.
The purpose of the study is to develop new biomarkers for studies of cystic fibrosis (CF). Defects in the gene encoding Cystic Fibrosis Transmembrane Regulator (CFTR) cause CF, an autosomal recessive disorder affecting mainly the pulmonary and digestive tract, leading to early death largely due to progressive loss of pulmonary function. In vitro experiments show that quercetin - a dietary supplement with a well-established safety profile for human use, including clinical trials in a variety of disorders encompassing cancer, heart disease, and as an anti-inflammatory agent - induces activation of CFTR. The nasal potential difference (NPD) test is a measurement of voltage across the nasal membrane and as a fundamental biomarker for CFTR activity in vivo. The NPD is a useful, well-established tool in CF research to determine both diagnoses as well as to measure the effect of new therapies. In vitro experiments show that quercetin induces activation of CFTR additive to that seen with current NPD reagents. In addition, it activates rescued mutant CFTR in vitro (∆F508 CFTR the most common cause of CF), whereas conventional agonists do not. Preliminary in vivo experiments mirrored these results and show that quercetin activates CFTR in human (n=12) NPD tests. Importantly, quercetin perfusion was well-tolerated by a validated sinus questionnaire and physician assessed nasal examination rating. These studies provide strong support for use of quercetin as potentiator of CFTR Cl- channel function by nasal administration. By adding quercetin to the sequence of perfusion solutions for NPD, the investigators may be better suited to detect ∆F508 CFTR activity of rescued mutant protein in the CF patient population.
