Active clinical trials for "Fibrosis"

This is a Phase 2, multi-center, double blind, placebo controlled study to evaluate the safety and tolerability of PBI-4050, and its effects on the pancreatic, pulmonary functions and on various biomarkers in Cystic Fibrosis patients with abnormal glucose tolerance. Patients with abnormal glucose tolerance have elevated glucose level either at 1 hour or 2 hour during an Oral Glucose Tolerance Test (OGTT). The Main study will include 24 weeks of treatment with PBI-4050 or matching placebo. At the end of the treatment period, patients will have the option of participating in a 24-week Extension study.

A study to evaluate the efficacy of inhaled molgramostim administered open-label to adult cystic fibrosis (CF) subjects with chronic pulmonary nontuberculous mycobacterial (NTM) infection, with or without ongoing antimycobacterial guideline based combination therapy.

Endothelin is a human hormone which has been associated with increased portal pressure in patients with liver cirrhosis (also called portal hypertension). Ambrisentan blocks the effects of endothelin. The purpose of this study is to evaluate the effect of ambrisentan on portal pressure and renal function in patients with advanced liver cirrhosis and with portal hypertension. In this study, portal pressure will be determined at multiple times with the aid of a catheter inserted into the body of the patient. The effect of ambrisentan on the function of the kidney will also be investigated. This study will also evaluate the concentrations of ambrisentan in blood in patients with liver cirrhosis.

The primary objectives of this study are to evaluate the effect of Elafibranor treatment compared to placebo on 1) histological improvement and 2) all-cause mortality and liver-related outcomes in patients with nonalcoholic steatohepatitis (NASH) and fibrosis.

To evaluate the efficacy of ivacaftor treatment, as measured by lung clearance index (LCI), in subjects with cystic fibrosis (CF) who have a specified CF transmembrane conductance regulator (CFTR) gating mutation

This study is designed as a masked, two center, randomized, placebo-controlled pilot study to evaluate the safety and efficacy of nasal and oral inhalation of 75 mg aztreonam in subjects with CF and lung infection due to PA. The study will involve two sites: Virginia Commonwealth University Medical Center (VCU) and Eastern Virginia Medical School (EVMS). Potential subjects will be identified in each site's CF clinic.

The aim of this study is to investigate the possibilities and effectiveness of managing cirrhotic portal hypertension using the non-invasive portal pressure gradient (PPG) detecting software. In this study, the three-dimensional reconstruction and natural follow-up methods have been respectively applied in the experimental (1st) and active comparator (2nd) group. The virtual PPG is calculated with anatomical and hemodynamic information of portal system collected by ultrasound and CT tests. Cirrhosis patients in the 1st group, with calculated vPPG values, are managed with upper GI endoscopic results. Besides, patients in the 2nd group, are managed according to the most updated Chinese clinical guideline for cirrhotic portal hypertension, namely, patients with either liver stiffness measurement (LSM) >15kPa or PLT count <150*10^9 should be screened and treated with upper GI endoscopy. The morbidity of decompensated cirrhotic events and mortality of patients in two arms will be compared. The cutoff values of vPPG to spare endoscopies with low missed VNT (varices needing treatment) are preliminarily determined with the cohort data.

This study will evaulate the long-term safety, efficacy and pharmacokinetics (PK) of recombinant human pentraxin-2 (rhPTX-2; PRM-151) zinpentraxin alfa, administered by intravenous (IV) infusion to participants with idiopathic pulmonary fibrosis (IPF).

This is a prospective, multi-center observational study. The study is designed to measure the clinical effectiveness of elexacaftor, tezacaftor and ivacaftor (ETI) triple combination therapy in children (6-11 years of old) with one or more copies of the F508del mutation, study the effects of ETI across a number of CF disease manifestations, and collect specimens for future research. Subjects in the study will have one "before ETI" visit within 30 days before initiation of the therapy and five "after ETI" visits over a 24-month follow-up period. Participants who have participated in the original PROMISE Pediatric Sub-Study have the option of participating in a long-term extension with annual visits performed at the 36- and 48-month timepoints. The durability of the clinical and biological changes in the PROMISE Pediatric Sub-Study can be assessed with extended follow-up, which would enable the sub-studies to consider potential clinical consequences of the biological or physiological effects being studied. This work will help to inform long term prognosis and feasibility of certain clinical trials outcomes for interventional studies and may be useful when considering research priorities in drug development. The duration of participation for each subject is 24 months (with an additional 24 months if participants agree to the optional long-term extension). NOTE: FDA has granted approval for elexacaftor, tezacaftor and ivacaftor in the 6-11 age group.

The COVID-19 pandemic is caused by the severe acute respiratory syndrome coronavirus 2 (SARS CoV-2), an emerging coronavirus, which has already infected 192 million people with a case fatality rate close to 2%. About 5% of patients infected with SARS CoV-2 have a critical form with organ failure. Among critical patients admitted to intensive care, about 70% of them will require ventilatory assistance by invasive mechanical ventilation (MV) with a mortality rate of 35% and a median MV duration of 12 days. The most severe lung damage resulting from SARS CoV-2 infection is the acute respiratory distress syndrome (ARDS). The virus infects alveolar epithelial cells and capillary endothelial cells leading to an activation of endothelium, hypercoagulability and thrombosis of pulmonary capillaries. This results in abnormal ventilation / perfusion ratios and profound hypoxemia. To date, the therapeutic management of severe SARS CoV-2 pneumonia lay on the early use of corticosteroids and Interleukin-6 (IL-6) receptor antagonist, which both reduce the need of MV and mortality. The risk factors of death in Intensive Care Unit (ICU) are: advanced age, severe obesity, coronary heart disease, active cancer, severe hypoxemia, and hepatic and renal failure on admission. Among MV patients, the death rate is doubled in those with both reduced thoracopulmonary compliance and elevated D-dimer levels. Patients with severe alveolar damage are at risk of progressing towards irreversible pulmonary fibrosis, the incidence of which still remain unknown. The diagnosis of pulmonary fibrosis is based on histology but there are some non-invasive alternative methods (serum or bronchoalveolar biomarkers, chest CT scan). We aim to assess the incidence of pulmonary fibrosis in patients with severe SARS CoV-2 related pneumonia. We will investigate the prognostic impact of fibrosis on mortality and the number of days alive free from MV at Day 90. Finally, we aim to identify risk factors of fibrosis.
