To learn if giving immune checkpoint therapy (such as atezolizumab) and bevacizumab to patients who have HCC and are receiving DAAs may help to control HCC and hepatitis C.
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.
A single-arm, single-center, open label Phase 1 study of a 12-week course of Sofosbuvir (SOF)/Velpatasvir (VEL) in 10 HCV-infected pregnant women 1 that will evaluate the plasma pharmacokinetic parameters of SOF/VEL administered during pregnancy and compare them to those of a historical cohort of nonpregnant women.
This is a multicenter, non-comparative, observational study that will recruit women with singleton pregnancy and chronic HCV infection to determine the natural history of chronic HCV in pregnancy and the rate of vertical transmission to their infants. All participants will be offered curative therapy with sofosbuvir/velpatasvir (Epclusa ®) after delivery and the cessation of breastfeeding. Subjects may be enrolled at any time after conception up through 36 weeks gestation. The management of subjects in pregnancy will be in accordance with ACOG guidelines and individual clinical judgment, however testing will include, but not be limited to, testing for HCV infection, HIV infection, HBV infection, HSV infection, group B Streptococcal colonization, HCV genotype, HCV viral load, as well as assessment of hepatic and renal function. Subjects will be followed on a schedule that is determined by their obstetric care providers throughout their pregnancy. Following delivery, infants will be evaluated at 12, 24 and 48 weeks of age, with testing for HCV RNA to be obtained at each evaluation. Vertical transmission is defined as two positive HCV RNA PCR tests, at least one before the 48 week infant visit, and again at the 12-month follow-up infant visit.
The purpose of this study is to assess the pharmacokinetics (PK), safety, and efficacy of oral MK-5172 (a fixed dose combination \[FDC\] tablet containing elbasvir \[EBR\] 50 mg and grazoprevir \[GZR\] 100 mg) and EBR/GZR (varying doses) pediatric granules in pediatric hepatitis C virus (HCV)-infected participants who are 3 to \<18 years of age. Within each age cohort (Cohort 1: 12 to \<18 years of age; Cohort 2: 7 to \<12 years of age; and Cohort 3: 3 to \<7 years of age), a Mini Cohort of 7 participants will be enrolled first. For the oldest cohort (Cohort 1), the Mini Cohort will assess ability to swallow a placebo tablet prior to administering active FDC tablets; participants in Cohorts 2 and 3 will take pediatric granules instead of a tablet.
Background: Treatment of some diseases can suppress the immune system. This can cause other conditions to reactivate. Recent cases have shown that hepatitis B virus (HBV) reactivates in people who had already recovered from it during treatment for chronic hepatitis C (CHC). Their treatment was direct-acting antiviral (DAA) agents. Researchers want to see how common this reactivation is. They want to learn what the effects are. They will study data that have already been collected. Objectives: To study HBV reactivation in people with CHC and resolved HBV infection who are being treated with interferon-free DAA-based therapy. Eligibility: Data were collected from adults 18 and older in studies that were done in 2012 and 2016. Design: Researchers will screen the records from the previous studies. They will identify participants who had HBV infection before they got DAA-based treatment. Researchers will take data from those records. This will include data on: * Age, sex, race, and ethnicity * Treatment and disease status * Lab results Researchers will test stored samples. They will test samples that were taken before, during, and after treatment. They will check if HBV was reactivated. They will also check if other clinical outcomes occurred.
The aim of this study is to determine if treatment monitoring schedule for chronic HCV patients treated with glecaprevir (300mg)/pibrentasvir (120mg) can be simplified. Data has shown that direct acting antiviral (DAA) regimen of glecaprevir (300mg)/pibrentasvir (120mg), a protease inhibitor and NS5A inhibitor respectively , provides key features for HCV treatment simplification. Eligible participants (naïve pre-cirrhosis chronic HCV patients) will be randomized (1:2) to the standard or simplified monitoring arm and will receive treatment for 8 weeks. One post treatment visit will be conducted 12 weeks after the final dose of study medication to evaluate the proportion of patients with undetectable HCV RNA at this timepoint (SVR12).
A Phase 3b, single arm, open-label, multicenter study in treatment naïve adults with chronic HCV infection and compensated cirrhosis to assess the safety of 8 weeks of treatment with glecaprevir/pibrentasvir and to demonstrate the efficacy of the sustained virologic response 12 weeks post dosing (SVR12) rates of 8 weeks of treatment with glecaprevir/pibrentasvir compared to the historical SVR12 rates of 12 weeks of treatment with glecaprevir/pibrentasvir.
This was a Phase 3b, open-label, non-randomized, multicenter study to evaluate the efficacy and safety of glecaprevir/pibrentasvir (GLE/PIB) in participants with chronic hepatitis C virus (HCV) genotype (GT) 1 - 6 infection without liver cirrhosis or with compensated liver cirrhosis and with chronic renal impairment in participants who were either HCV treatment-naïve (TN) or prior treatment-experienced (TE) with interferon (IFN) or pegylated interferon (PegIFN) with or without ribavirin (RBV), or sofosbuvir (SOF) plus RBV with or without pegIFN.
The objectives of this study are to assess the pharmacokinetics, safety, and efficacy of glecaprevir/pibrentasvir adult formulation in adolescents ages 12 to 17 years and a pediatric formulation of glecaprevir and pibrentasvir in children ages 3 to \< 12 years.
Incorporating Hepatitis C Virus (HCV) treatment into opioid maintenance treatment program clinical protocols is an innovative health care delivery model that has been associated with improved HCV treatment uptake in non-pregnant, drug-using populations. This "medical home" approach would combine HCV and opioid maintenance treatment into one treatment regimen and incorporate the expertise of obstetricians, hepatologists, substance abuse treatment providers and pediatricians into one comprehensive clinical care model. The purpose of this study is to evaluate the feasibility/acceptability of a combined, peripartum HCV and opioid maintenance treatment program on adherence to HCV treatment regimens and evaluate the rate of intravenous drug use (IVDU) recidivism, HCV reinfection and health related Quality of Life (QOL) in women with opioid use disorder (OUD) during the first postpartum year. The protocol involves three separate study phases. All 3 study phases will occur with support from hepatology providers at Magee-Womens Hospital. Phase 1 involves screening, enrollment and a baseline assessment of liver function, HCV infection (genotype, viral load) and blood and urine studies in HCV-infected patients during pregnancy. In Phase 2, subjects will undergo 12 weeks of sofosbuvir/velpatasvir therapy initiated at 2 weeks postpartum. Feasibility/acceptability and adherence to sofosbuvir/velpatasvir will be assessed at 4, 8 and 12 weeks of therapy. In Phase 3, subjects will continue to be followed for 15 months after treatment completion. Treatment effectiveness and sustained virologic response (SVR) will be evaluated at 3 months and rates of IVDU recidivism, HCV reinfection and patient centered outcomes such as health related quality of life (QOL) will be assessed at 6, 9 and 12 months following treatment completion.
The primary objectives of this study are to evaluate the safety, efficacy and tolerability of treatment with ledipasvir/sofosbuvir (LDV/SOF) in adults with chronic HCV infection who are on dialysis for ESRD.
This study will have 2 parts: Pharmacokinetics (PK) Lead-in Phase and the Treatment Phase. The primary objective of the PK Lead-in Phase is to evaluate the steady state PK and confirm the dose of sofosbuvir/velpatasvir (SOF/VEL) fixed-dose combination (FDC) in pediatric participants with chronic hepatitis C virus (HCV) infection. The primary objective of the Treatment Phase is to evaluate the safety and tolerability of SOF/VEL for 12 weeks in pediatric participants with chronic HCV.
The primary objectives of this study are to evaluate the efficacy, safety, and tolerability of the treatment with sofosbuvir velpatasvir (SOF/VEL) fixed-dose combination (FDC) with ribavirin (RBV) for 12 weeks in participants with chronic hepatitis C virus (HCV) infection and Child-Pugh-Turcotte (CPT) Class C cirrhosis.
To address the need for more affordable hepatitis C virus (HCV) antivirals with high barriers to viral resistance and strategies to shorten the current treatment duration, the goal is to develop affordable therapeutic regimens to prevent HCV entry/spread and test the efficacy of those inhibitors for treating HCV infection. The investigators recently discovered that a major cholesterol uptake receptor is required for HCV entry into hepatocytes and that there is already an FDA-approved drug that inhibits cholesterol uptake by this receptor. Importantly the same drug also potently blocks HCV entry in human liver cells both in cell culture and in a small animal model. Further, looking back at people who were previously treated for HCV infection, the investigators found treatment response to be better (i.e. larger viral log reduction) in patients who happened to be taking ezetimibe (EZE). Hence, the objective of this study is to assess whether the FDA-approved drug (ezetimibe) is useful for the treatment of chronic HCV. The investigators predict that when administered as monotherapy ezetimibe will reduce HCV viremia perhaps allowing for viral clearance and that when included in combination treatment regimens that EZE will increase HCV decline resulting in faster viral clearance (i.e. shorter/cheaper direct-acting antiviral \[DAA\] therapy). To test these hypotheses, the investigators will execute the following aims: (1) Assess the efficacy of EZE monotherapy in chronically HCV infected and predict time to cure; (2) Assess the efficacy of EZE as an adjunct therapy in chronically HCV infected patients undergoing currently approved HCV DAA treatment.
A Phase 3b, open-label, multicenter study to evaluate the efficacy and safety of glecaprevir/pibrentasvir for an 8- or 12-week treatment duration in participants with chronic hepatitis C virus (HCV) genotype (GT) 5 or 6 infection, with or without compensated cirrhosis respectively.

Participants randomized to placebo may be eligible for deferred treatment with active SOF/VEL/VOX.
This Registry will enroll adolescent and pediatric participants who received at least one Gilead Hepatitis C Virus (HCV) direct acting antiviral (DAA) while participating in a Gilead-sponsored chronic hepatitis C clinical trial. The primary objective of this Registry is to determine the long-term safety of anti-HCV regimens in the pediatric population. Secondary objectives of this Registry are to determine whether subsequent detection of HCV RNA in participants who relapse following sustained virologic response (SVR) represents the re-emergence of pre-existing virus, the development of resistance mutations, or whether it is due to re-infection, and to characterize resistance mutations and the persistence of resistance mutations in pediatric participants who did not achieve SVR. Once enrolled, participants will be followed for up to 5 years.
The goal of this pilot study is to examine both efficacy and tolerability in patients with HCV genotype 1 and mild decompensation with Child-Pugh-Turcott score of 6 or lower. The CPT score is used to assess the prognosis of chronic liver diseases, as well as the required strength and treatment and necessity of liver transplantation. A higher CPT score denotes higher necessity of liver transplantation.
