Filter by:This is a dose escalation/dose finding, double-blind, placebo-controlled, parallel study of GSK2126458 in subjects with IPF. The study is designed to explore a number of doses of GSK2126458 for engagement of pharmacology after short term dosing. It is anticipated that approximately 24 subjects will be enrolled in this study. Actual number of cohorts in this study could vary up to a maximum of 6 cohorts (n=4/cohort; 3 on active and 1 on placebo). Each cohort will consist of four subjects who will be randomised to receive GSK2126458 (three subjects) or placebo (one subject) for approximately 8 days (7 to 10 days). On Day 1 they will receive their first dose of GSK2126458 (or placebo) and safety, tolerability and PK/PD in the blood will be measured for up to 8 hours post-dose. Subjects will then be discharged from the site with study drug until the last day of dosing. They will also receive hand held spirometers and instructions on action to be taken in case of deterioration in pulmonary function or any other adverse events (AEs). On the last day of dosing they will return to the site for a repeat of the Day 1 procedures. A bronchoalveolar lavage (BAL) and [18F]-fluoro-deoxyglucose (FDG)- positron emission tomography / computed tomography (PET/CT) scan will be conducted twice during the study; once, at least 2 days before dosing commences and again during the course of the dosing period. After the final subject in each cohort has completed dosing, a dose escalation meeting will take place. Safety and tolerability and PK data will be reviewed during this meeting and decisions made may include but are not limited to: escalate the dose, decrease the dose or repeat the same dose in the next cohort; stop the study.
Hepatic encephalopathy (HE) is a potentially reversible functional disorder of the brain with neurological and psychiatric symptoms. HE occurs in up to 70% of patients with cirrhosis at some time during the course of disease. The chief neurotoxin implicated in the development of HE is ammonia. An important aim of treatment of HE is the reduction of the ammonia in the body by lowering the amount of ammonia produced and increasing its detoxification. Enteric production of ammonia can be decreased by non-absorbable disaccharides such as lactulose and antibiotics such as rifaximin. L-ornithine- L-aspartate (LOLA), the salt of the natural amino acids ornithine and aspartate acts through the mechanism of substrate activation to detoxify ammonia. In clinical trials, LOLA has shown a statistically significant effect with respect to reduction in HE grade, reduction of blood ammonia concentration and positive effects on psychomotor function in patients of cirrhosis with minimal HE and overt chronic Grade I HE, as compared to placebo. However, there is lack of data on the efficacy of LOLA in patients with overt acute hepatic encephalopathy which is one of the major causes of hospital admissions and resource utilization in decompensated cirrhotics. Each admission for HE causes a major financial loss to the family and financial burden on the society. Any drug which decreases the hospital stay by rapidly improving HE, will clearly lead to decreased hospital costs to the individual and the society as a whole. Hence, such a trial is a national priority. The investigators hypothesize that LOLA, if added to the standard treatment of overt acute HE (i.e lactulose), may lead to a faster recovery and decrease in hospital stay of these patients. In this prospective, randomized, placebo controlled trial, the investigators aim to evaluate the efficacy of intravenous L-ornithine, L-aspartate in reversal of overt acute hepatic encephalopathy in patients with liver cirrhosis.
This pilot study will be conducted in adolescents with cystic fibrosis (CF) without diabetes but with abnormal glucose tolerance, and will assess the effects of sitagliptin on glucose regulation. An oral glucose tolerance test (OGTT) and a mixed meal tolerance test (MMTT), will be performed at baseline and again ~4 weeks after treatment with study drug. We will also look at blood sugars throughout the day using a continuous glucose monitor (CGM) before each time the MMTT/OGTT are performed. Several hormones that may affect the way the body regulates blood sugars will be measured in blood when the OGTT and MMTT are done. We will assess the effect this medicine has on blood sugars (using CGM) and the effect the medicine has on the hormones measured during the OGTT and MMTT.
Drug discovery can take many years especially since most studies to measure effectiveness depend on clinical outcomes like pulmonary function tests and hospitalizations. This is an observational study designed to collect information, blood, and bronchoalveolar lavage fluid in people who have IPF and those who do not. The people who have IPF will be followed for 12 months to collect more biological samples and record clinically relevant information. The goal of this study is to identify new molecular markers that are measurable and reliable in people who have IPF. It is hoped that these markers can be used in future drug studies to significantly speed up the process of finding drugs that help.
This phase IV, multicenter, randomized, open-label, two-period crossover study will evaluate the comparable efficacy and safety of Pulmozyme (dornase alfa) delivered by the eRapid nebulizer system in patients with cystic fibrosis. Patients who have been receiving Pulmozyme once daily chronically for at least 6 months will continue to receive Pulmozyme once daily for a run-in period of 2 weeks using the Pari LC Plus nebulizer. Patients will then be randomized to receive in a crossover design Pulmozyme once daily for two treatment periods of 2 weeks each using either the Pari LC Plus or the eRapid nebulizer. Anticipated time on study treatment is 6 weeks.
The purpose of this Randomized, Double-blind, Multicenter, Two-period Crossover Study is to Assess the Efficacy and Tolerability of Burlulipase (NM-BL) in Patients with Exocrine Pancreatic Insufficiency due to Cystic Fibrosis
An open label study in 40-60 subjects with diagnosed lung airway disease and in 10-20 normal controls. Each subject will receive PFP as a contrast agent to visualize the airway and alveolar spaces in their lungs using magnetic resonance imaging of inert gas/oxygen mixtures.
The investigators hypothesize that measurement of beta adrenergic induced sweat rate using an evaporimeter can accurately and reliably determine different levels of CFTR dysfunction within a spectrum of patients expressing various degrees of cystic fibrosis disease. The investigators overall goal is to determine whether the evaporimeter technique of measuring beta-adrenergic induced sweat rate is capable of accurately and reliably identifying different levels of CFTR dysfunction, as a prerequisite before advancing this technique as biomarker assay into clinical trials.
Background: Hepatitis C recurrence, which invariably occurs in viremic liver transplant (LT) recipients, associated with accelerated liver fibrosis leading to established graft cirrhosis in 40-20% of patients in 5 years with another 5% experiencing an aggressive form with cirrhosis and graft loss in 1 year. Since treatment after LT has a low efficacy, the overall survival of HCV-infected LT recipients is shorter than that of uninfected LT patients. New immunosuppressive agents such as mTOR inhibitors (Everolimus/Sirolimus) reduce the risk of liver graft rejection, have antifibrotic properties and do not worsen HCV recurrence. Moreover new directly-acting antiviral agents have increased efficacy of interferon-based treatment but their use in LT recipients may be limited by side effects. Hypothesis: Use of individualized immunosuppressive regimen and early personalized anti-viral treatment based on recipient and viral factors would improve outcome of HCV infected liver transplant recipients. Objectives: 1. To evaluate safety and efficacy of two steroid-free immunosuppressive regimens to reduce hepatitis C recurrence associated to fibrosis progression (F≥2 under ISHAK score) at one year post-transplant. 2. To identify viral and recipient factors associated with liver fibrosis progression using ultra-deep pyrosequencing (UDPS).
The primary objective of this study is to assess the safety and tolerability of simtuzumab (formerly GS-6624) in HIV and/or hepatitis C virus (HCV)-infected adults with evidence of liver fibrosis.
