A Phase 2a, Double-Blind, Placebo-Controlled Study to Evaluate Pharmacodynamics, Pharmacokinetics, and Safety of BLD-2660 Administered Orally in Subjects with Idiopathic Pulmonary Fibrosis

Small Intestinal Bacterial Overgrowth (SIBO) is a common and increasingly recognized disorder in cirrhosis (30% to 73%). One of the most important predisposing factors of SIBO is small bowel dysmotility. Multiple studies have shown that the presence of SIBO is strongly linked to the pathogenesis of Minimal Hepatic Encephalopathy (MHE) also known as Covert Hepatic Encephalopathy (CHE). Consequently, altering and modulating the intestinal microbiota with ammonia-lowering agents and Rifaximin has been the target treatment strategy in CHE. The aim of this study is to determine the therapeutic effect of Rifaximin on patients with CHE and underlying SIBO while assessing the influence of Rifaximin on small bowel motility. In this prospective interventional study, 40 patients with liver cirrhosis will be screened for Covert Hepatic Encephalopathy (CHE) using neuro-psychometric tests. Patients diagnosed with CHE will undergo breath test (BT) for SIBO screening. Afterwards, wireless motility capsule (The SmartPill) will be performed in all patients with a positive BT. Thereafter, the cirrhotic patients diagnosed with CHE and SIBO will receive Rifaximin 550 mg PO twice daily for eight weeks. At the end of treatment, neuro-psychometric tests will be repeated to evaluate the therapeutic effect on CHE. In addition, BT and SmartPill will be repeated at the completion of the Rifaximin treatment period to assess the effect on small bowel motility. All collected clinical parameters at the end of the study will be compared to baseline values.

The purpose of this study is to evaluate the safety and tolerability of captopril and evaluate the effectiveness captopril as measured by changes in the grade of bone marrow scar tissue. The change in spleen size by ultrasound will also be measured.

The general aim of this project is to conduct a randomized, double-blind, placebo-controlled clinical trial of azithromycin to determine whether treatment from infancy is safe and will prevent the onset of bronchiectasis. One hundred and thirty infants will be recruited from CF clinics in Australia and New Zealand and treated from 3 months to three years of age. The primary outcome will be the proportion with radiologically-defined bronchiectasis at 3 years of age. Safety and mechanistic evaluations will also be undertaken.

The investigators conducted a pilot study including 17 patients with liver cirrhosis showing that a moderate exercise programme during three months increased thigh circumference,exercise tolerance and quality of life without adverse effects. The present study aim to more accurately evaluate the effect of exercise on muscle mass, effort tolerance and inflammatory response in patients with cirrhosis. This study will include 30 patients with compensated liver cirrhosis that will be randomized into two groups: exercise group and control group. Evaluation of muscle mass, effort tolerance, inflammatory response and quality of life will be made at the beginning and at the end of the study.

The disposition of NRL972 after a 15-second intravenous injection of 2 mg NRL972 is distinctly slower in patients with hepatic cirrhosis and acute hepatitis than in healthy control subjects. NRL972 appears to be a suitable investigational marker of hepatic transporter clearance dysfunction. Although the pharmacokinetics of NRL972 provide a reliable differentiation between subject groups, this approach relies on precisely timed sampling of venous blood, cautious preparation, handling and on-site storage of plasma samples, the transfer of samples to a central laboratory for analysis, and the availability of a validated assay procedure. For these reasons, there is interest in developing and validating alternative methods for determining the concentration of NRL972 in venous blood. Two such methods have been developed to date, but their utility in determining NRL972 pharmacokinetics has yet to be established.

The primary objective of this study is to measure efficacy of our new protocol by monitoring the results of our routine respiratory cultures at the end of the new standard treatment, and during routine visits for 1 year from initiation of therapy for Staphylococcus aureus. The secondary objective will include determining the clinical course (pulmonary exacerbations, antibiotic use, hospitalizations, pulmonary function tests) of patients who underwent the protocol.

Patients of cirrhosis with portal hypertension aged 18 to 75 years who have small esophageal varices with or without red color signs and have not bled previously will be enrolled. After baseline evaluation, the participants will be randomized to receive either Placebo or Carvedilol 12.5 mg BD. After randomization they will be followed up for one year. The primary endpoint of the study is the the proportions of patients who develop large varices (Gd 3 or Gd 4) at 1 year in each group. The secondary endpoint are survival,reduction in HVPG,change in CTP and MELD score& adverse events.

Cystic Fibrosis (CF), the most common inherited disease in Caucasians, is characterized by chronic pulmonary inflammation and progressive loss of gas exchange units that eventually results in respiratory failure. There is strong evidence that, in CF, abnormally low perfusion carries a high risk of death independent from the presence of pulmonary hypertension. However, the evolution of pulmonary vascular disease in CF and how it might contribute to the rate of decline in lung function is not known. Our knowledge remains limited to the results of old observational studies which concluded that the major causes of pulmonary vascular remodeling and hypertension in CF are hypoxic respiratory failure and destruction of lung tissue. Our recent data obtained by state-of-the-art Magnetic Resonance Imaging (MRI) of the pulmonary circulation, challenges the existing paradigm. We demonstrate that in the absence of hypoxia, significant changes in pulmonary perfusion and in surrogate measures of vascular resistance as well as in collateral blood flow begin early in the course of CF. Newly developed therapeutics have altered dramatically the course of patients suffering from pulmonary vascular disease. Through this 8 week trial, we will examine by Magnetic Resonance Imaging the effect of Sildenafil on pulmonary perfusion and systemic vascularization of the lungs in subjects with mild to moderate disease.
