Active clinical trials for "Fibrosis"

This study compares gadolinium contrast-enhanced Abbreviated MRI (AMRI) to standard ultrasound for Hepatocellular Carcinoma (HCC) screening and surveillance in subjects with liver cirrhosis.

Positron Emission Tomography (PET) provides a valuable tool for the diagnosis and staging of liver fibrosis. Activation of hepatic stellate cell (HSC) is a key link in the pathophysiological development of liver fibrosis. In human liver tissue, fibroblast activation protein (FAP) was only expressed in active HSCs and fibroblasts, but not in static HSCs. Therefore, FAP has become an excellent target for diagnosis and treatment of liver fibrosis. Recently, radionuclide-labeled fibroblast activation protein inhibitors (FAPI) as a new novel positron tracer has shown to be effective to detect various cancers. In this prospective study, the investigators will use the most advanced imaging equipments, integrated PET/MR, and PET/CT with gallium-68 (68Ga) -FAPI to image patients with or suspected of liver fibrosis, the aim is to explore the value of 68Ga-FAPI hybrid PET/MR and PET/CT in liver fibrosis.

Portal hypertension is characterised by an increased portal pressure gradient (PPG), that is the difference in pressure between the portal vein and the inferior vena cava (IVC). Portal hypertension is a consequence of cirrhosis resulting from chronic hepatitis. Patients with portal hypertension are at risk of developing complications including oesophageal or gastric varices, variceal bleeding, ascites, spontaneous bacterial peritonitis, hepatic encephalopathy and mortality. Albeit its clinical significance, direct measurement of portal venous pressure to document portal hypertension has traditionally been difficult. The portal vein pressure can be measured by transhepatic or transvenous methods but the procedure carries a risk of intra-peritoneal bleeding. Furthermore, the IVC pressure measurement requires further transjugular catheterisation. Hence, the technique is rarely used. Currently, the gold standard in measurement of portal hypertension is via measurement hepatic venous pressure gradient (HVPG). The HVPG has been shown to correlate with risk of clinical decompensation, development of varices, hepatocellular carcinoma, variceal bleeding, spontaneous bacterial peritonitis and mortality. Nevertheless, the technique has a low acceptance rate amongst patients and it may not be available even in tertiary medical centres. Recently, the use of EUS-guided approach for measurement of portal pressure gradient (PPGM) has been shown to be feasible. The technical success rate was 100% and no adverse events were reported. Measurements obtained with the EUS approach was shown to correlate excellently with clinical parameters of portal hypertension including presence of varices, portal hypertensive gastropathy and thrombocytopenia. Furthermore, the procedure could be performed at the same time of screening oesophagogastroduodenoscopy (OGD), that is frequently required for variceal screening in this group of patients. Hence, the aim of the current study is to investigate the feasibility of EUS-PPGM and correlate the risk of developing complications with the PPGM in patients that are suffering from chronic hepatitis.

The purpose of this study is to evaluate the long term safety, tolerability, efficacy and pharmacodynamics of elexacaftor (ELX)/tezacaftor (TEZ)/ivacaftor (IVA) in CF participants 2 years of age and older.

The FIBROPANC-1 investigates the feasibility and safety of preoperative stereotactic radiotherapy of 4cm pancreas in patients undergoing pancreatoduodenectomy at high risk (>25%) of developing post operative pancreatic fistula (POPF). A single course of 12Gy preoperative radiotherapy may lead to sufficient fibrosis in a small (4cm) targeted area, thereby reducing the risk of grade B and C POPF.

To evaluate the potential value of 68Ga-FAPI-04 positron emission tomography/computed tomography (PET/CT) for the diagnosis and prognosis in liver fibrosis disease.

The purpose of this study is being done to determine whether magnetic resonance imaging (MRI) using inhaled hyper-polarized 129 Xenon gas can help visualize impaired lung function to detect changes over time in Idiopathic Pulmonary Fibrosis (IPF) patients receiving approved IPF treatments. Subjects will undergo an approximately hour long comprehensive MRI protocol, including administration of multiple doses of hyper-polarized 129 Xenon. The subjects will have this initial study prior to initiation of IPF therapies. Then the subjects will have repeat studies at 3, 6 and 12 months following the initiation of therapy. Additional studies including pulmonary function studies, serum for bio markers, 6 minute walk distance and a high-resolution computed tomography (HRCT) scan (only at the 6 month visit) will be performed to determine how 129 Xenon MRI performs relative to standard of care evaluations for IPF. The MRI uses a magnet and radio waves to make diagnostic medical images of the body. There have been no ill effects reported from exposure to the magnetism or radio waves used in this test. Risks of the xenon gas are slight numbness in legs, nausea, a feeling of well-being, and mild tingling in fingertips. You will have pulmonary function testing for the study, you may experience breathlessness or dizziness during or immediately following these tests.

Detection of Integrin avb6 in Idiopathic Pulmonary Fibrosis, Primary Sclerosing Cholangitis, and Coronavirus Disease 2019 with [18F]FP-R01-MG-F2 with PET/CT

This is a randomized, double-blind, placebo-controlled trial in de novo kidney transplant patients to determine if the addition of fingolimod (brand name Gilenya®, candidate name- FTY720) on the background of standard immunosuppression will prevent expansion of the interstitial compartment of the transplanted kidney. Interstitial expansion is the precursor of interstitial fibrosis and graft loss. The study will test the hypothesis that abgrogating the fibrogenic effects of both the RhoA and mTOR pathways with fingolimod will reduce structural damage in transplanted kidneys and possible subsequent transplant failure.

This is a prospective exploratory biodistribution study in patients with interstitial lung disease (ILD). The purpose of this research study is to determine where and to which degree the FAPI tracer (68Ga-FAPI-46) accumulates in normal and fibrotic lung tissues of patients with interstitial lung disease. The study will include patients with interstitial lung disease who have or will initiate a new ILD medication OR will undergo tissue biopsy or surgery of the lung. The study will include 30 patients, the upper limit for PET imaging studies conducted under the Radioactive Drug Research Committee (RDRC) purview. Participants will be injected with up to 7 mCi of 68-GaFAPi and will undergo one PET/CT scan and one High Resolution CT of the lungs. The study is sponsored by Ahmanson Translational Theranostic Division at UCLA.
