It may scar the liver. This is called cirrhosis and may lead to liver cancer or death. Current chronic hepatitis C treatments cure most people. But some keep getting complications even after it is cured. Researchers want to study why.\n\nObjective:\n\nTo study the course and complications of liver disease after cure of hepatitis C infection.\n\nEligibility:\n\nAdults 18 years and older infected with chronic hepatitis C virus who were never treated or were treated and not cured and those who were cured\n\nDesign:\n\nParticipants will be screened with:\n\nBlood and urine tests\n\nQuestionnaires\n\nLiver ultrasound\n\nFibroscan. A probe vibrates the liver, testing stiffness.\n\nIn Phase 1, people with chronic hepatitis C will:\n\nHave a 3-day hospital admission to repeat some screening tests and have a liver biopsy. A small piece of liver is removed by needle passed through the skin.\n\nTake 1 tablet containing 2 hepatitis C drugs once a day for 12 weeks.\n\nRepeat some blood tests at 3 visits in those 12 weeks while on treatment, then 4 additional visits in the next 24 weeks with more blood work collected.\n\nPhase 1 participants who test negative for hepatitis C and all other eligible participants will enter Phase 2.\n\nPhase 2 participants will have a visit every 24 weeks for 10 years. These may include:\n\nRepeats of screening tests\n\nQuestionnaires\n\nScans\n\nStool tests\n\nChest x-ray\n\nHeart function test\n\nEndoscopy. A tube guides a camera into the upper digestive system.\n\nAt about 5 years, participants will have another liver biopsy.\n\nSome participants will give separate consent for genetic testing and a special blood procedure.', 'detailedDescription': 'Study Description:\\<TAB\\>\n\nWe intend to enroll up to 350 subjects with chronic hepatitis C virus (HCV) infection. Subjects will be recruited from two sources:\n\n1. Phase I: treatment na(SqrRoot) ve or experienced who have failed a prior treatment (including DAA-experienced) who are willing to undergo a pre-treatment liver biopsy.\n\n 1. Subjects yet to achieve an SVR will receive 12 weeks of therapy with sofosbuvir/velapatasvir (Epclusa(R)) fixed dose combination\n 2. Subjects yet to achieve SVR with evidence of clinical cirrhosis will undergo a transjugular liver biopsy with hepatic venous portal gradient (HVPG) pressure measurements in lieu of the percutaneous liver biopsy\n2. Phase II: subjects who have already achieved sustained virologic response (SVR) with oral direct-acting antiviral agent (DAA) only regimen and who have undergone a liver biopsy prior to therapy and no history of hepatic decompensation or hepatocellular carcinoma.\n\n Subjects who have attained an SVR prior to enrollment (or upon achieving an SVR12 and SVR24 in Phase I) will undergo a thorough medical evaluation:\n * laboratory testing\n * Fibroscan(R)\n * hepatic ultrasound\n\n Thereafter, subjects will be followed prospectively every 24 weeks for liver decompensation (ascites, spontaneous bacterial peritonitis, hepatic encephalopathy, variceal hemorrhage), hepatocellular carcinoma, liver-related mortality, and all-cause mortality. During each study visit, subjects will be questioned on the development of these adverse outcomes. In addition, blood will be drawn for the assessment of routine blood tests, quantitative viral biomarker levels, serological response markers and immune cell functional status. Blood, urine, and stool will be collected and stored for exploratory biomarker development. Fibroscan(R) will be performed annually in all subjects. For subjects with cirrhosis, esophagogastroduodenoscopy (EGD) will be performed annually and imaging every 24 weeks. At the end of 240 weeks, all subjects will be admitted for a liver biopsy to assess the stage of liver fibrosis. In subjects with cirrhosis at study entry, the liver biopsy will be performed by the transjugular route with hepatic venous portal gradient (HVPG) pressure measurements.\n\n The primary goal of the study will be to describe the outcome of viral eradication following treatment with direct acting antiviral agents, to identify predictors of adverse outcomes after sustained viral eradication and regression of fibrosis/cirrhosis.\n\n Objectives:\n\n Primary Objective:\n * Phase 1: SVR12 and SVR24\n * Phase II: The rate of clinical outcomes (ascites, spontaneous bacterial peritonitis, hepatic encephalopathy, variceal hemorrhage), hepatocellular carcinoma, liver-related mortality, and all-cause mortality\n\n Secondary Objectives:\n * Phase II: The proportion and rates of fibrosis regression in subjects\n * Phase II: The agreement between Fibroscan and Ishak fibrosis score\n * Phase II: The comparison of change in Fibroscan and change in Ishak fibrosis as predictors of the primary outcome.\n * Phase II: To assess regression of portal hypertension in subjects with pre-existing portal hypertension either confirmed by direct portal pressure measurement, indirectly by hepatic venous pressure gradient or clinical evidence of portal hypertension such as presence of esophageal or gastric varices of portal hypertensive gastropathy and all-cause mortality.\n\n Exploratory Objective:\n * To develop novel biomarkers and genetic predictors of liver-related complications including hepatocellular carcinoma.\n * To assess outcome of HCV-related immune dysfunction following sustained eradication of HCV.\n * To assess changes in antibody titer and breadth, B cell activation, and T cell memory after sustained HCV eradication.\n * To prospectively assess the rate of non-hepatic outcomes (diabetes, cardiovascular and renal disease, malignancy including lymphoma, and health related quality of life) following SVR with DAA agents.\n * To characterize the changes in serum lipids and lipoproteins during and after therapy with direct acting antiviral agents and assess cardiovascular risk following eradication of HCV based on serum/plasma LDL particle number.\n\n Endpoints:\n\n Primary Endpoint:\n * SVR at 12 weeks after completion of 12 weeks of treatment.\n * Composite of ascites, spontaneous bacterial peritonitis, hepatic encephalopathy, variceal hemorrhage, hepatocellular carcinoma, liver-related mortality, and all-cause mortality at 480 weeks.\n\n Secondary Endpoints:\n * Improvement in semi-quantitative Ishak fibrosis score after HCV clearance.\n * Correlation between Fibroscan (transient elastography) with Ishak fibrosis score after HCV clearance.\n * Does change improvement in Fibroscan and change in Ishak fibrosis correlate with clinical outcome.\n * Change in portal pressure after SVR12.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '120 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': '* INCLUSION CRITERIA:\n\nPhase I Treatment\n\n* Male or female \\>= 18 years of age\n* Either treatment naive or experienced defined as failure of a prior course of interferon-based and ribavirin, DAA plus interferon and DAA only\n* Confirmation of chronic HCV infection documented by:\n\n * A positive HCV RNA or positive HCV genotyping test at least 6-months prior to the Baseline/Day 1 visit\n * A liver biopsy performed prior to screening visit showing evidence of chronic hepatitis.\n* Subjects must have the following laboratory parameters at screening:\n\n * ALT \\<= 10 x the upper limit of normal (ULN)\n * AST \\<= 10 x ULN\n * Total bilirubin \\<2.5 mg/dL, Direct bilirubin \\<= 1.5 ULN\n * Platelets \\>= 50,000 K/mm\\^3\n * HbA1c \\<= 8.5%\n * Hemoglobin \\>= 10g/dL\n * Albumin \\>= 3g/dL\n * INR \\<= 1.5 unless subject has known hemophilia or is stable on an anticoagulant regimen affecting INR.\n * HCV RNA positive at screening.\n* Subjects must be of generally good health, with the exception of chronic HCV infection, as determined by the Investigator.\n\nPhase II Follow-up\n\n* Male or female \\>= 18 years of age.\n* SVR24 following therapy with a direct acting antiviral agent regimen and available liver biopsy performed prior to treatment.\n* Subject must be of generally good health as determined by the Investigator.\n\nEXCLUSION CRITERIA:\n\nAn individual who meets any of the following criteria will be excluded from participation in this study:\n\nPhase I Treatment\n\n* Pregnancy or lactation\n* Inability to practice one form of adequate contraction for females of childbearing potential\n* Prior treatment with a NS5a agent\n* Current or prior history of any of the following:\n\n * Clinically significant illness (other than HCV) or any other major medical disorder that may interfere with subject treatment, assessment, or compliance with the protocol;
