NCT04596475
This trial will be done in participants who undergo transplantation of heart, kidney or lung at University of California, San Diego (UCSD) and receive a hepatitis C infected donor organ. In this trial, the plan is to start hepatitis C treatment just before transplant surgery and treat for a short one-week course to see if hepatitis C infection can be prevented in the transplant recipient. The plan is to perform this trial in 10 participants and if successful, the next step is to try to make it standard of care as prevention of infection is better than treating hepatitis C after discharge from transplant surgery (which is usually a 12 week standard treatment).
NCT01037621
This trial is to determine the safety of valacyclovir in persons with chronic hepatitis C and herpes simplex type 2 infection. Participants will be randomized to valacyclovir or matching placebo. After receiving the initial therapy for eight weeks, the participants will cross over to the alternate therapy for an additional eight weeks. Each treatment period will be separated by a two-week period of daily placebo. The hypothesis is that treatment with valacyclovir will result in a significant reduction in serum levels of hepatitis C virus ribonucleic acid.
NCT00570336
The purpose of this study is to determine if CTS-1027 can lower elevated liver enzymes in patients with chronic HCV infection.
NCT04971330
The objective of this study was the collection and testing of clinical samples to determine the clinical performance in terms of diagnostic accuracy measured by specificity and sensitivity of the Access anti-Hepatitis C Virus (anti-HCV) assay on the DxI 9000 Access Immunoassay Analyzer. The Design Input Document (DID) indicates performance requirements and minimum target enrollment numbers (based on those in the CTS) of blood donor, hospitalized patient and known HCV antibody (Ab) positive samples for novel anti-HCV assays. A secondary objective was to determine the false initial reactive rate (IRR) of the Access anti-HCV assay.
NCT00671671
Phase 1 study in HVC (Hepatitis C Virus) infected subjects to determine pharmacokinetics, safety and efficacy in subjects with no or inadequate response to prior treatment.
NCT00563173
The purpose of this study is to evaluate if the DNA vaccine CHRONVAC-C® intended for future treatment of Hepatitis C infections is safe and tolerated when administered to HCV infected individuals with a low viral load. In addition the capability of the vaccine to induce an immune response and the effect on viral load will be studied. In order to increase the uptake of the vaccine the intra muscular injection is combined with electroporation, meaning that a brief electric field is applied to the injection site resulting in temporary pores in the cell membranes that allows the vaccine to enter the cells.
NCT00819026
Hepatitis C Virus is constantly evolving genetically, particularly in response to the immune system. This is an observational study to examine if immunosuppressants particularly calcineurin inhibitors taken by transplant patients in order to avoid organ rejection causes predictable changes in the genetics of this virus that might be important in order to treat it effectively.
NCT04112303
The primary objectives of this study are to evaluate the antiviral efficacy, safety, and tolerability of therapy with sofosbuvir/velpatasvir (SOF/VEL) fixed-dose combination (FDC) in adults with chronic hepatitis C virus (HCV) infection and compensated cirrhosis.
NCT06953479
The goal of this clinical trial is to learn whether a low-barrier treatment program can help people with hepatitis C virus (HCV) who are in jail start and complete treatment more easily. This study focuses on adults at the Rhode Island Department of Corrections who have active HCV and are awaiting trial. The study asks: * Can a simplified, low-barrier HCV treatment program work in a jail setting? * Do participants finish treatment and get cured using this approach? All participants will receive a 12-week course of the HCV medication sofosbuvir/velpatasvir (Epclusa). If they are released before completing treatment, they will take the remaining doses with them. Community Health Workers (CHWs) will help support participants after release, including reminding them to take medications and helping them get follow-up lab work. Researchers will measure: * Whether participants are cured of HCV * Whether the treatment approach is easy to use (feasible), acceptable, and followed correctly (fidelity) * Whether the program could be used in other jails or expanded in the future This study may help bring HCV treatment to more people in jail, reduce community spread of the virus, and support national goals to eliminate HCV.
NCT02722837
The primary objective of this study is to evaluate the efficacy, safety, and tolerability of treatment with sofosbuvir/velpatasvir (SOF/VEL) fixed-dose combination (FDC) for 12 weeks in participants with chronic hepatitis C virus (HCV) infection.
NCT00382798
This is an adaptive Phase I study to evaluate RO5024048 in the following groups: * Healthy Volunteers (Part 1 - Single Ascending Dose Study) -Enrollment completed * Hepatitis C virus (HCV) genotype 1 infected patients who have failed interferon therapy (Part 2- Multiple Ascending Dose Study)-Enrollment Completed * HCV genotype 1-infected patients who are treatment naive, to be dosed in combination with PEG-IFN and RBV (Part 3 - Combination Dose Study)-Currently Enrolling * HCV genotype 2-3 infected patients who have previously been treated with interferon but who did not respond, to be dosed in combination with PEG-IFN and RBV (Part 3 - Combination Dose Study)- Currently enrolling The study aims to determine if RO5024048 is safe and well-tolerated in healthy people and in people infected with hepatitis C virus. The amount of RO5024048 in the blood will be measured during the study and the amount of hepatitis C virus in the blood after each dose will also be measured. During Part 3 of the study, RO5024048 will be given with PEG-IFN and RBV, two drugs currently used and approved for the treatment of HCV.
NCT02833298
Approximately half of the patients receiving treatment for chronic hepatitis C virus (HCV) infection in the United States have advanced liver disease. Patients with advanced fibrosis/cirrhosis who achieve a sustained virological response (SVR) to treatment and are clinically cured of HCV continue to have an elevated risk of developing hepatocellular carcinoma (HCC). According to guidelines from several professional societies and from the American Association for the Study of Liver Diseases (AASLD), in particular, patients with advanced fibrosis/cirrhosis should undergo life-long bi-annual screening for incident HCC whether they achieve an SVR, or not. The number of patients who need post-SVR HCC screening has risen dramatically in recent years due to the confluence of three factors: Increased screening for HCV, which has allowed more people to realize that they have this often "silent" infection; the availability of safe and highly effective direct acting antiviral drugs (DAAs) for HCV, which has allowed a much higher percentage of treated patients to achieve an SVR; and the long duration of HCV infection in many patients, which has allowed enough time for advanced fibrosis/cirrhosis to develop. To investigate post-SVR patients in the era of DAAs and to promote HCC screening, the objective of this study is to conduct a randomized, unblinded, two-arm prospective intervention trial comparing rates of HCC screening between patients randomized to either personalized patient navigation or automated reminders (e.g. electronic or mailed). Both interventions represent improved care over current standard of care (no patient navigation or automated reminders). There is no evidence to suggest one intervention is better than the other. Healthcare providers who agree to participate in the study will be contacted to confirm the liver disease status of their patients and during the clinical trial the providers of patients in both arms of the trial will be sent reminders about the need to schedule patients for screening visits.
NCT02671500
The primary objectives of this study are to evaluate the efficacy, safety, and tolerability of treatment with sofosbuvir (SOF)/velpatasvir (VEL; GS-5816) fixed-dose combination (FDC) for 12 weeks in participants with chronic hepatitis C virus (HCV) infection.
NCT01573351
The purpose of this study is to assess efficacy, as determined by the proportion of subjects with Sustained Virologic Response at Post-Treatment Week 12 (SVR12), defined as Hepatitis C virus (HCV) Ribonucleic acid (RNA) \< Limit of quantitation (LOQ) at post-treatment Week 12.
NCT01836718
The purpose of this study is to measure intrahepatic HCV RNA levels at the time of liver transplantation in patients receiving antiviral therapy while on the liver transplant waiting list. This will eventually be correlated with the degree of hepatic fibrosis present within different geographic sites in the cirrhotic liver. Tissue samples will be obtained from the patient's liver explant as well as hilar lymph nodes. Upon the removal of the cirrhotic liver at the time of transplantation, the explant will be biopsied multiple times in different segments of the liver and preserved for viral detection studies as well as analysis of the degree of fibrosis. Peripheral blood mononuclear cells (PBMCs) will be obtained for viral detection at the time of transplantation. Serum HCV RNA levels will also be obtained at 1 month, 3 months and 6 months post liver transplantation. Study Hypotheses: * Virological relapse or non-response is higher is patients with cirrhosis due to failure of antiviral medication to concentrate adequately in a fibrotic liver having an altered sinusoidal micro-architecture * HCV may persist in different geographic regions of the fibrotic liver in part predicated on blood supply to that area and this may have an effect on overall virological response. These differences in viral persistence and detection may exist in different lobes of the liver or even within a few centimeters within the same portion of the liver parenchyma. * PBMC and hilar lymph nodes may be extrahepatic reservoirs of HCV viral persistence in patients receiving antiviral therapy and may account for virological relapse post-therapy * There may be varying degrees of fibrosis within the same cirrhotic liver which may impact on hepatic synthetic function and antiviral response to treatment.
