Clinical Trial Summary

Primary sclerosing cholangitis (PSC) is a chronic liver disease that can lead to liver cirrhosis, liver failure and liver cancer. Assessment of disease status is important to determine optimal treatment but the diagnosis of PSC is challenging. There is a dire need of an accurate non-invasive tool for longitudinal assessment of PSC. MR Elastography (MRE) has been recently proven to estimate liver fibrosis noninvasively and accurately. Estimation of liver fibrosis by MRE along with imaging derived morphological information (MRCP) will be utilized in this study comprehensively to provide a surrogate non-invasive imaging biomarker for monitoring disease status in PSC. Successful outcomes will provide an opportunity for optimal treatment triage including liver transplantation via accurate and non-invasive estimation of true disease status in PSC.


Description:

Primary sclerosing cholangitis (PSC) is a chronic liver disease that causes inflammation and obstruction of bile ducts. It can eventually lead to liver cirrhosis due to fibrosis, liver failure and liver cancer. The diagnosis of PSC is challenging as there is no single diagnostic test and usually involves a multidisciplinary approach with MRI playing a major role. Assessment of disease status is important to triage patients for optimal treatment including liver transplantation and prevention of liver failure. There are however no established blood tests that can reliably track the disease progression and repeated liver biopsies have multiple drawbacks including complications, costs and feasibility. There is a dire need of an accurate non-invasive tool for longitudinal assessment of PSC. MR Elastography (MRE) has been recently proven to estimate liver fibrosis noninvasively and accurately. Estimation of liver fibrosis by MRE along with imaging derived morphological information (MRCP) will be utilized in this study comprehensively to provide a surrogate non-invasive imaging biomarker for monitoring disease status in PSC. The patients would have or will agree to undergo a liver FibroScan examination to grade fibrosis within 3 months of the MRI examination. In addition to the standard protocol liver and biliary MR examination including MRCP and contrast enhanced imaging, MRE will be added to the study exam following informed consent. A control group of non-PSC subjects with known chronic liver disease such as chronic viral hepatitis who have had liver biopsy and FibroScan within similar time frame of 3 months, to assess fibrosis grade will also undergo MR Elastography in order to validate the results of fibrosis by MRE. The study has significant implications for care of patients with PSC. Successful outcomes will provide an opportunity for optimal treatment triage including liver transplantation via accurate and non-invasive estimation of true disease status in PSC.
