People With CHC Who Achieved a Sustained Virological Response Following Therapy With Direct Acting Antiviral Agents

Background: Chronic hepatitis C infects the liver. 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. Objective: To study the course and complications of liver disease after cure of hepatitis C infection. Eligibility: Adults 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 Design: Participants will be screened with: Blood and urine tests Questionnaires Liver ultrasound Fibroscan. A probe vibrates the liver, testing stiffness. In Phase 1, people with chronic hepatitis C will: Have 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. Take 1 tablet containing 2 hepatitis C drugs once a day for 12 weeks. Repeat 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. Phase 1 participants who test negative for hepatitis C and all other eligible participants will enter Phase 2. Phase 2 participants will have a visit every 24 weeks for 10 years. These may include: Repeats of screening tests Questionnaires Scans Stool tests Chest x-ray Heart function test Endoscopy. A tube guides a camera into the upper digestive system. At about 5 years, participants will have another liver biopsy. Some participants will give separate consent for genetic testing and a special blood procedure....

Sofosbuvir/Velpatasvir Treatment of Chronic Hepatitis C During Pregnancy

This is a multicenter, single arm study of Sofosbuvir/Velpatasvir (SOF/VEL) for treatment of chronic hepatitis C infection during pregnancy. Treatment will be initiated during the second or third trimester in approximately 100 pregnant people. Maternal participants will take one SOF/VEL tablet once daily for 12 weeks (84 days) and followed until 12 weeks after treatment completion (postpartum). Infants will be followed from birth until one year of age. The primary objectives are to evaluate the sustained virologic response 12 weeks after completion of SOF/VEL treatment (SVR12) in participants treated during pregnancy and to evaluate impact of antenatal treatment with SOF/VEL on the gestational age at delivery.

C-Forward: Efficacy and Safety of BEM/RZR vs SOF/VEL in Subjects With Chronic HCV

The purpose of this study is to compare the efficacy and safety of BEM/RZR to SOF/VEL in adults with chronic HCV.

Use of Gender, Age, Alfa-fetoprotein (AFP), and Des-gamma-carboxyprothrombin (PIVKA-II) or GAAD Score in Addition to Ultrasound for Surveillance of People At-risk for Developing Hepatocellular Carcinoma in Asia in Order to Detect Early Liver Cancer

HCC surveillance is currently limited by underutilization and the suboptimal performance of AFP. This prospective, single-arm study investigates whether the GAAD score (Gender, Age, AFP, and PIVKA-II) enhances HCC detection when added to standard-of-care surveillance. High-risk patients will undergo US plus GAAD score testing every six months for two years. The primary analysis compares the relative true positive rate (rTPR) and relative false positive rate (rFPR) of surveillance modalities (US, AFP, GAAD) against combined strategies (US+AFP; US+GAAD), utilizing a 2.57 GAAD cut-off. Secondary endpoints include longitudinal biomarker kinetics, early-stage HCC detection rates, and the impact on downstream imaging (CT/MRI) volume. Ultimately, this study seeks to define the role of GAAD as a surveillance adjunct and inform future clinical guidelines for biomarker-enhanced HCC screening.

Enhancing Hepatitis C Testing and Treatment Among People Who Inject Drugs Attending Needle and Syringe Programs

This project aims to evaluate two strategies of Hepatitis C virus (HCV) testing compared to standard of care among people who inject drugs at needle and syringe program (NSP) services in Australia, to see if it can improve the number of people who start treatment following an HCV diagnosis: 1. HCV testing from collected dried blood spots sent to a central laboratory 2. HCV testing using a point-of-care device at the NSP site 3. HCV testing using standard of care at the NSP site

Treating Hepatitis C in Pakistan. Strategies to Avoid Resistance to Antiviral Drugs

We will determine how best to manage the hepatitis C virus (HCV) epidemic in Pakistan by measuring effectiveness of Pakistan-government sponsored current therapies, emergence of viral resistance, consequences of infection (chiefly liver cancer) and through developing models, based on incidence data, determine the proportion of people who need curative treatment to eliminate HCV, and assess whether targeting can optimise this.

Digitalized Surveillance Management for Liver Cancer Risk Population in Improving Eearly Diagnosis Efficancy in Chinese Population (dSEARCH)

The goal of this study is to evaluate whether the standardized liver cancer risk stratification management can effectively improve the early diagnosis rate of liver cancer in the targeted risk population in China.

Nation-wide Hepatitis C Virus (HCV) Registry in Taiwan

To determine the treatment efficacy, safety and long-term outcomes of chronic hepatitis C patients receiving directly acting antivirals in Taiwan

Prospective Observational Study of Disease Progression in Chronic Hepatitis C

The purpose of this study is to determine the progression of chronic hepatitis C patients infected by paid plasma donation,and explore the possible pathogenic mechanisms of disease progression in chronic hepatitis C.
