Active clinical trials for "Fibrosis"

This study will assess the effect of pancrelipase delayed release 24,000 unit capsules on fat and nitrogen absorption in subjects with PEI due to Cystic Fibrosis.

The standard treatment for decompensated cirrhosis is liver transplantation, however, it has several limitations. Recent animal studies suggest that bone marrow stem cell transplantation can lead to regression of liver fibrosis. The investigators have already completed the phase 1 study of bone marrow mesenchymal stem cell (MSC) transplantation in 4 patients with cirrhosis. The procedure was safe, and feasible, and led to somewhat promising results (Mohamadnejad M, et al. 2006; Submitted for publication). The aim of this study is to find efficacy of this new treatment strategy in the setting of a multicenter, randomized placebo-controlled trial in 50 patients with decompensated cirrhosis.

A study to determine the safety, effectiveness, and acceptability of 2 methods of administration of EUR-1008 (APT-1008) (Zenpep® [pancrelipase] delayed release capsule) 3,000 lipase units capsule, a pancreatic enzyme product (PEP), in infants with exocrine pancreatic insufficiency (EPI) due to cystic fibrosis (CF). This study is sponsored by Aptalis Pharma (formerly Eurand).

The objective of the study was evaluate the effect of administration of midodrine and albumin on renal function in patients with cirrhosis and creatinine greater than 1,2mg/dl.

Patients with advanced cirrhosis have abnormal translocation of Gram-negative bacteria across the intestinal barrier and subsequent systemic inflammatory response. We hypothesized that this translocation may worsen the underlying liver disease. Thus, the aim of this trial was to assess the effects of the oral administration of norfloxacin (an antibiotic that suppresses intestinal Gram-negative bacteria) on the development of complications of cirrhosis.

Background: Alcohol is one of principal causes of hepatic fibrosis. Although the most effective treatment for alcoholic hepatic fibrosis is abstinence of alcohol consumption, additive treatment to reduce the accumulation of scar tissue can accelerate the improvement of hepatic fibrosis in alcoholic liver disease. The renin-angiotensin system can be an attractive antifibrotic target in liver. Several lines of evidence indicate that overproduction of angiotensin II(ANG II) in chronic liver injury stimulates the activation of hepatic stellate cells(HSCs) attributed to fibrogenesis. Additionally, the antifibrotic effect of ANG II blocking agent has been shown in various animal models and hepatitis C patients. Hence, drugs that inhibit the renin-angiotensin system have promise in ameliorating hepatic fibrosis in chronic liver injury. However, no study has been conducted in patients with alcoholic liver disease to evaluate the effect ANG II type I receptor blocking agent on hepatic fibrosis. Aim: This study aimed to investigate the safety and the efficacy of chronic administration of candesartan to hepatic fibrosis patients with alcoholic liver disease. Methods 1) Patients with liver fibrosis(F2) were randomized to receive either the angiotensin receptor blocker(ARB), candesartan(8 mg/day) with ursodeoxycholic acid(UDCA)(600 mg/day)(n = 42), or UDCA alone(n = 43) as control for 6 months. 2)All enrolled patients underwent liver biopsies twice for measurement of fibrosis score, area of fibrosis and alpha-smooth muscle actin(SMA) positive and hydroxyproline. 3) Transforming growth factor-beta1(TGF-beta1), collagen-1, angiotensin II type I receptor(AT1-R), tissue inhibitor of metalloproteinase-1(TIMP-1), Rac1 and p22phox which represent oxidant stress were also measured by real-time RT-PCR before and after 6 months of therapy.

The purpose of this study is to determine whether choosing antibiotics based on a biofilm antimicrobial susceptibility assay rather than a conventional planktonic antimicrobial susceptibility assay to treat CF patients with chronic P. aeruginosa infection with an acute pulmonary exacerbation is a safe intervention that will result in improved microbiological and clinical outcomes and decrease markers of pulmonary inflammation.

A major factor in the respiratory health of cystic fibrosis (CF) subjects is acquisition of chronic Pseudomonas aeruginosa infections. The infection rate with P. aeruginosa increases with age and by age 18 years, 80% of CF subjects in the U.S. are infected. Liposomal Amikacin for Inhalation (Arikace™) is a sterile aqueous liposomal suspension consisting of amikacin sulfate encapsulated in liposomes. This formulation of amikacin maximizes the achievable dose and delivery to the lungs of subjects infected via a nebulizer. Because liposome particles are small enough to penetrate and diffuse through sputum into the bacterial biofilm, they deposit drug in close proximity to the bacterial colonies, thus improving the bioavailability of amikacin at the infection site. The clinically achievable doses of amikacin in the LAI formulation can effectively increase the half-life of the drug in the lungs, and decrease the potential for systemic toxicity. LAI offers several advantages over current therapies in treating CF subjects with chronic infection caused by P. aeruginosa.

The objectives of the study are to demonstrate that Tobrineb®/Actitob®/Bramitob® is non-inferior to TOBI® in the primary efficacy variable, forced expiratory volume in one second (FEV1) percent of predicted normal, and to compare the safety in participants with cystic fibrosis and chronic infection of the lungs with Pseudomonas aeruginosa.

This Phase IIB proof-of-concept study would examine the effects of an investigational product called N-acetylcysteine (NAC) on the basic processes that cause inflammation in CF lung disease. We hope to learn more about the causes of lung disease in cystic fibrosis by studying the characteristics of the inflammation in the lungs of patients who have CF.
