Treatment of HOsPitalised Inpatients for Hepatitis C (TOPIC): Therapeutic Intervention Enhancing Care Linkage in People Who Inject Drugs

This study will evaluate the proportion of patients achieving confirmed SVR12 (undetectable HCV RNA at time point 12 weeks plus post treatment commencement) in patients hospitalised for IRID (injecting related infectious diseases) and commencing inpatient DAA treatment within public hospital services.

Proteogenomic Monitoring and Assessment of Liver Transplant Recipients

This study is being done to test blood, urine and tissue samples to see if this can help decide if CKD (Chronic Kidney Disease), AR (Acute Rejection) and HCV (Hepatitis C Virus) can be identified in its early stages. CKD damage to the kidneys, AR and HCV all lower the body's ability to function properly. Early detection of these conditions could assist with successful treatment and possibly lead to less repeat organ transplants.

Epidemiology, Infectivity and Natural History of Hepatitis C Virus Infection

This study will evaluate hepatitis C virus (HCV) infection in blood donors who test positive for antibodies to this virus. Most HCV-infected people do not become ill and are not aware that they have hepatitis or have had it in the past. Some infected people recover completely, whereas others remain chronically infected. The study will try to define infectivity of anti-HCV positive individuals, routes of transmission of the virus, and the number of HCV-infected persons who have evidence of liver disease. Blood donors at the NIH Clinical Center or the Central Maryland Chapter of the American Red Cross who test positive for HCV may be eligible for this study. Participants will have a physical examination and history, including questions about socioeconomic status and current sexual practices. They will have 100 milliliters (ml) (6 tablespoons) of blood drawn at the first visit and 50 ml (3 tablespoons) drawn 3, 6, 9 and 12 months after the initial visit. Some participants may undergo plasmapheresis, a procedure for collecting additional plasma (the liquid portion of the blood). For this procedure, whole blood is collected through a needle placed in an arm vein. The blood circulates through a machine that separates it into its components. The plasma is then removed, and the red and white cells and platelets are returned to the body, either through the same needle used to draw the blood or through a second needle placed in the other arm. In some individuals, other body fluids (saliva, urine or semen) may also be collected. Participants may be asked to bring their household contacts and sexual partners to NIH for interview and blood testing for evidence of HCV infection and liver disease. Although this is not required for participation in the study, it would provide additional valuable information. Participants found to have chronic viral infection will be seen more often and will provide additional blood samples for routine medical care. Further medical evaluation may include X-rays or liver scans and referral to a specialist for additional tests or therapy. Ten people in this study will be recruited to participate in a secondary investigation to analyze changes in the level of HCV and the immune response to it, and to relate these changes to the degree of liver damage. In addition to blood collected for the primary study, participants in this investigation will have an additional 50 ml (3 tablespoons) of blood drawn from an arm vein every week for 10 weeks to measure levels of virus, ALT (a liver enzyme), and immune response.

Evaluation of Patients With Liver Disease

The proposed study aims to evaluate, investigate, and follow-up patients suffering from acute and chronic liver disease. The study will focus on understanding diseases affecting the liver. Patients participating in the study will first undergo a routine check-up as an outpatient. They will be asked to provide blood and urine samples for laboratory testing and will undergo an ultrasound of the liver. Ultrasound examinations use sound waves to determine the size and texture of the liver. After the initial visit subjects will be requested to follow-up once a year at the outpatient department for a similar check-up. Additional tests may be requested throughout the study to provide information for other research studies and individual consent will be requested. These tests may include liver biopsies, skin biopsies, and / or specialized blood, plasma, and lymphocyte examinations. Subjects that qualify for medications presently being studied may be offered the opportunity to benefit from experimental therapy.

Tele-Harm Reduction

The purpose of this study is to test 2 different methods for offering medications that treat HIV, cure Hepatitis C Virus (HCV) (if applicable) and treat substance use disorder (if desired) to people who inject drugs.

Hepatitis C Screening Paired With Mammography

In France, a breast cancer screening is organized since 2004 for women aged 50-74. On the other hand, even though the seroprevalence of hepatitis C in the general French population is less than 1%, it is estimated that more than 75,000 people live with the virus without knowing it. To answer the WHO objective of eliminating hepatitis C by 2030 and in France by 2025, the investigators need to organize targeted screening. Women aged more than 50 years old, by their possible antecedents in life, are an exposed population. The investigators propose to pair the already organized breast cancer screening with a hepatitis-screening test by rapid diagnostic orientation test (TROD) and evaluate the adherence of women in this paired screening. For women with positive TROD, a specialized care will be organized.

Lung Transplant HCV, Pilot Study

In this study HCV negative recipients will be transplanted with HCV positive lungs. Investigators will attempt to decrease infectivity rates by performing Normothermic Ex vivo Lung Perfusion (EVLP), which is an approved method of donor lung preservation, assessment and treatment, and could be an excellent platform to reduce/eliminate hepatitis C virus. Patients will be treated by the standard approved direct-acting antivirals (DAAs) if infection occurs. It is planned to enroll 20 patients from the Lung transplant wait list in this study. Patients will be actively followed for 6 months including HCV PCR tests and then for up for 5 years to look for evidence of HCV infection and any liver or extra-hepatic complications, as well as standard post-transplant complications. This will be a single center pilot study.

A Phase 1 Clinical Trial of Adjuvanted Protein-based HCV Vaccine Candidates (HCV Vaccine Trial)

The purpose of this study is to investigate the safety and antibody (germ fighters) response of the experimental (investigational) vaccine against HCV when injected into the arm of healthy adults.

Hepatitis B and Hepatitis C as Risk Factors for Hepatocellular Carcinoma in African and Asian Immigrants

The prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) in the United States (US) is relatively low. However, immigrant populations in the US from Asia and sub-Saharan Africa have substantially higher prevalence than the general population and are consequently at a significant risk for hepatocellular carcinoma (HCC). Indeed, the age-adjusted incidence rates for HCC in the US have tripled from 1975 to 2005. As the population demographics have changed, the 2000 US census estimated the number of Somalis in Minnesota at 25,000 but current estimates put the number at around 50,000 due to primary refugee arrivals as well as secondary immigration from other states. There is no available data for Somali immigrants in the US on HBV and HCV prevalence, HBV and HCV genotypes/subgenotypes, and genetic and immunologic risk factors predisposing Somalis to HBV and HCV and the subsequent development of HCC. Therefore. this study will fill these gaps in the Somali population to understand the relative importance of HBV and HCV infections in causation of HCC. Besides Somalis, Minnesota is also home to large other African immigrant communities. According to the Minnesota Department of Health (MDH), in 2013, the highest rates of chronic HBV cases where reported among Asian or Pacific Islanders (3,638 cases per 100,000 persons) followed by Black or African Americans (2,078 cases per 100,000 persons). Additionally, Minnesota receives a large number of new refugee's resettlement. It is important to improve the identification of chronic HBV and HCV infections among Somali refugees and immigrants in Minnesota through well-designed community-wide screening efforts. Since we know that African immigration to Minnesota is the third highest in the US, this unique population might be a contributing factor to the increased burden of hepatitis and liver cancer complications in the state of Minnesota. Findings from HBV and HCV screening among Somalis suggest that other immigrant African populations from high viral hepatitis endemic regions, such Ethiopia, Liberia, and Kenya, are also at substantial risk of HBV, HCV and HCC. Unfortunately, very little research has been conducted in the US on the burden of hepatitis and liver cancer in African Immigrants from areas of high endemicity of hepatitis B and hepatitis C. Therefore, the goal of is to identify HBV and HCV and the role viral genetics and immune response among African immigrant communities from Kenya, Liberia, and Ethiopia.

Study of the Pharmacokinetics and Safety of Glecaprevir/Pibrentasvir Initiated in Pregnancy in Women With Hepatitis C With and Without HIV

This is a Phase I/II, multi-site, open-label, single arm study to describe the pharmacokinetics (PK) and safety of glecaprevir/pibrentasvir (GLE/PIB) initiated during pregnancy in women with hepatitis C virus (HCV) infection (acute or chronic) with or without HIV and to evaluate safety for their infants through 10 weeks postpartum.

Advanced Care Coordination and Enhanced Linkage and Retention Among Transitional Re-Entrants

The overarching goal of this study is to develop a peer-based care coordination intervention for individuals with Hepatitis C Virus (HCV) who were recently released from correctional settings to promote linkage to and retention in HCV care. The investigators will assess the existing barriers and facilitators of HCV treatment initiation, HCV treatment completion, and sustained virologic response among individuals recently released from a U.S. jail or prisons in a randomized control trial. This study will assess the feasibility and process measures of a peer-enhanced HCV care coordination intervention among recently incarcerated individuals.

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.

The Australian HCV Point-of-Care Testing Program

The National Australian HCV Point-of-Care Testing Program will establish an observational cohort to evaluate whether scale-up of finger-stick point-of-care HCV testing increases diagnosis and treatment for HCV infection. Participants will be recruited from settings providing services to people with a risk factor for the acquisition of HCV infection (including drug treatment clinics, needle and syringe programs, homelessness settings, mental health services, prisons, and mobile outreach). Participants will attend a single visit to have their HCV RNA status tested and complete a self-administered survey. Participants will not receive treatment as a part of this study. Participants who are HCV RNA positive will be linked to standard of care.

The 1200 Patients Project: Studying the Implementation of Clinical Pharmacogenomic Testing

The purpose of this study is to collect DNA samples from patients undergoing routine care at the University of Chicago. These samples will be tested for differences in genes that may suggest greater risk of side effects or chance of increased benefit from certain medications. The results will be made available to the patient's treating physician and the researchers will track whether or not this information is used in routine health care.

Aims: Aim 1 - Evaluate adherence and treatment completion rates when glecaprevir-pibrentasvir is started during pregnancy for women who use drugs. Aim 2 - Evaluate patient experience with hepatitis C virus treatment during pregnancy.

Use of a Patient-Centered Electronic App to Increase ED Patient's Knowledge on HCV to Improve the HCV Care Continuum

The investigators will conduct a randomized controlled clinical trial study in an urban emergency department in Baltimore to determine the impact of an educational app which is based on Leventhal's Common-Sense Model of Illness Representations framework, on HCV-infected ED patient's hepatitis C virus (HCV) health belief and knowledge as well as the downstream outcomes of the HCV Continuum of Care (linkage to care rate, initiation of HCV antiviral treatment, and sustained virologic response). First, the investigators will develop a blueprinted prototype personalized HCV educational app which will (1) provide individualized liver fibrosis staging information, (2) pre-test HCV knowledge, perception of barriers to HCV care, and motivation to receive HCV care survey, (3) provide personalized HCV knowledge, facilitators and supporting information for HCV care via video clips and information sheets based on the pre-test results, and (4) provide post-test knowledge, perception, and motivation to receive HCV care. Second, the investigators will conduct a series of focus group discussion sessions to fine-tune the HCV educational app. Third, the investigators will enroll ED patients who have anti-HCV (newly diagnosed or previously diagnosed) but without HCV RNA testing information for a pilot randomized controlled clinical trial of the personalized HCV educational app.

A Study to Evaluate Preemptive Therapy in Hepatitis C (HCV) Organ Transplant Recipients

This study is being done to determine the effectiveness of using a combination of two different drugs in preventing the transmission of HCV from a HCV positive donor to a HCV negative solid organ recipient.

Expanding the Pool in Orthotopic Heart Transplantation

This is an open-label, pilot trial to test the safety and efficacy of transplantation of hearts from HCV seropositive non-viremic (HCV Ab+/NAT-) and HCV seropositive viremic (HCV Ab+/NAT+) donors to HCV seronegative recipients on the heart transplant waitlist. Treatment and prophylaxis will be administered, using a transmission-triggered approach for the first scenario (HCV Ab+/NAT- donors, arm 1) and a prophylaxis approach for the later scenario (HCV Ab+/NAT+ donors, arm 2).

Therapy for Hepatitis C Virus (HCV) in Primary Treatment Failure in Pakistan

This trial is linked to a largescale observational study determining the efficacy of sofosbuvir/daclatasvir in people in Pakistan (involving a separate protocol). The observational study will identify a cohort of patients who have not responded to first-line antiviral therapy (sofosbuvir plus daclatasvir) and the optimal treatment for these patients is unclear. This trial will address this issue by comparing two second-line treatment regimens to determine the preferred treatment option.

ED Patient's Perceptions and Acceptability Toward a Novel POC HCV Viral Load Testing

Hepatitis C virus (HCV) infection has become the leading fatal infectious disease in the United States. Approximately 75% of individuals who have been infected with HCV are chronically infected with the virus. Untreated chronic infection will lead to severe sequelae such as cirrhosis and hepatocellular carcinoma. Even though the availability of rapid HCV antibody (HCV Ab) screening assay and highly effective antiviral treatment, most people infected with HCV are not aware of the infection status. This gap mainly comes from the current gold standard confirmatory testing for chronic HCV infection, the Polymerase Chain Reaction (PCR)-based HCV RNA viral load assay which requires an experienced trained laboratory technician to perform relatively complicated PCR assay with a turn-around-time of 1 to 2 days (from provider's order to the test resulting). The investigators' rapid HCV Screening and Linkage to Care program has demonstrated that many patients in the investigators' emergency department (ED) are unaware of patient's chronic HCV infection status due to the barriers to receive the gold standard viral load testing. Recently, a novel Xpert HCV Viral Load (VL) Finger-stick (FS) \[Xpert HCV VL FS\] point-of-care (POC) test (Cepheid) has been developed. In an observational cohort in Australia, HCV RNA was detected in 40% of participants (85 of 210) enrolled at 3 drug treatment clinics and 1 homelessness service. Sensitivity of the Xpert HCV VL FS assay for HCV RNA quantification in samples collected by finger-stick was 100.0% (95% Confidence Interval (CI), 93.9%-100.0%) and specificity was 100.0% (95% CI, 96.6%-100.0%). The Xpert HCV VL FS test can accurately detect active infection from a finger-stick sample in 1 hour allowing single-visit HCV diagnosis. In this protocol, the investigators seek to determine the needs and acceptability of a novel POC HCV viral load testing assay among ED HCV Ab positive patients. For this project, the investigators will identify and enroll ED patients with HCV Ab positive but without HCV viral information. The investigators will conduct a randomized study to assign eligible and consented patients to either to POC Testing Group or Standard of Care (SOC) Group. All participants will take a short survey regarding HCV care and treatment. As part of the investigators' ED HCV Screening and Linkage to Care Program, all participants will receive the standard-of-care clinical laboratory-based HCV RNA viral load testing via whole blood (i.e. patient will receive blood drawn). This standard-of-care HCV viral load testing result will be provided to participant when it is available (usually 1-2 days later). Participants in the POC Testing Group will receive the novel POC HCV RNA viral load testing and the result of the novel test will be disclosed to the patients approximately within 2 hours of the testing. Linkage to care information after the ED visit will be compared between two groups. Finally, accuracy of this POC HCV RNA viral load testing in the acute care setting will be determined as compared to the standard-of-care clinical laboratory-based HCV RNA viral load testing. The investigators will also ask all of participants to grant permission to use the remnant blood specimens for an evaluation of future in-house HCV RNA viral load assay.

The Use of Hepatitis C Positive Kidneys in Hepatitis C Negative Kidney Transplant Recipients

This is an open-label, pilot trial to test the safety and efficacy of transplantation of kidneys from hepatitis C seropositive non-viremic (HCV Ab+/NAT-) and HCV seropositive viremic (HCV Ab+/NAT+) donors to HCV seronegative recipients on the kidney transplant waitlist. Treatment and prophylaxis will be administered using a transmission-triggered approach for the first scenario (HCV Ab+/NAT- donors, arm 1) and a prophylaxis approach for the later scenario (HCV Ab+/NAT+ donors, arm 2).
