Filter by:Data are limited regarding the effectiveness and safety of generic velpatasvir plus sofosbuvir (VEL/SOF) with or without ribavirin (RBV) for the treatment of hepatitis C virus (HCV) in patients with human immunodeficiency virus (HIV) coinfection. We aim to compare the effectiveness and safety of VEL/SOF with and without RBV for 12 weeks in HIV/HCV-coinfected and HCV-monoinfected patients The antiviral responses and the adverse events (AEs) are compare between the two groups. The characteristics potentially related to sustained virologic response 12 weeks off therapy (SVR12) are analyzed.
The development of direct acting anti-virals (DAAs) for the treatment of Hepatitis C virus (HCV) has changed the landscape of HCV therapy dramatically in the last several years with reported sustained virologic response (SVR) rates in excess of 95% for treatment-naïve HCV positive patients including those who have received liver or kidney transplants. Since these new regimens do not include interferon and have already been studied in the post-liver and kidney transplant setting, they now offer a unique opportunity to expand the donor pool and improve the lives of those awaiting renal transplant. The address this gap in knowledge, the investigators hypothesize that pre-emptive treatment with a direct acting anti-viral HCV medication to cure HCV soon after transplant would allow for safe transplantation of HCV positive kidneys in disadvantaged and needy HCV negative kidney recipients with acceptable risks and improved survivals compared with historical cohorts.
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.
Objectives: The general objective of the present project is to gain a better understanding of disease outcome in cACLD patients treated with the new oral DAA. In particular, the project will focus on: - To evaluate the long term prognosis of patients with compensated advanced chronic liver disease (cACLD) who achieve sustained virological response (SVR) after the new oral direct-acting antiviral agents (DAA), and determine clinical and elastographic basal and follow-up parameters to identify low and high risk groups of developing liver-related decompensation. Methods: Prospective cohort study in patients with cACLD in whom basal and annual clinical features and liver stiffness measurements (LSM) will be performed, and survival free of liver-related events will be analyzed.
The goal of this study is to assess the health literacy level of patients enrolled in the HOPE program, identify any gaps in their knowledge of hepatitis C, analyze the variables that may influence patients' knowledge, and educate patients on Hepatitis C.
Treatment of CHB patients with genotypic resistance to NUCs has been problematic due to the lack of data from randomized trials. Recently, two randomized trials comparing the efficacy of TDF monotherapy versus TDF and ETV combination therapy in CHB patients with documented genotypic resistance to adefovir (ADV) or ETV demonstrated TDF monotherapy was not statistically different in viral suppression at week 48 of treatment.1,2 The extension study based on the above two trials merged study subjects from these trials with changing from TDF and ETV combination group to TDF monotherapy to evaluate long-term efficacy and safety of TDF monotherapy for multidrug-resistant patients. At the time of merging of 192 subjects, by intention-to-treat analysis, 66.3% of TDF group and 68.0% of TDF-ETV group had virological response as determined by serum HBV DNA <15 IU/mL. (in press) Three year long-term follow up study showed that the proportion of virologic suppression increased to 76.8% and 72.2% in TDF-TDF and TDF/TDF-ETV groups, respectively( P=0.46). (in press) TAF, a novel prodrug of tenofovir was developed to have greater stability in plasma than TDF, thereby enabling more efficient delivery of the active metabolite to target cells at a substantially lower dose. The reduced systemic exposure of tenofovir offers the potential for an improved safety profile compared to TDF a benefit that demonstrated in a recent clinical trial in patients with HIV infection. In a recent double-blind randomized phase 3 noninferiority trial with 873 treatment naive patients who were positive for HBeAg, the proportion of patients receiving TAF who had HBV DNA <29 IU/mL at week 48 was 64%, which was non-inferior to the rate of 67% in patients receiving TDF (P=0.25).3 In the safety profile, TAF group had significantly smaller decrease in BMD than TDF group in the hip and spine, as well as significantly smaller increases in serum creatinine at week 48.3 For treatment naive HBeAg negative patients, a recent study with 425 subjects applied the same methodology and showed noninferiority in efficacy of TAF compared to TDF at week 48.4 Considering noninferiority in efficacy and superior bone and renal safety from TAF, TAF might be considered preferred choice of NUC instead of TDF. However, it is still unknown whether TAF would show similar efficacy and safety profile in patients with multidrug-resistant CHB.
This study will evaluate the efficacy and safety of glecaprevir/pibrentasvir (ABT-493/ABT-530) in chronic hepatitis C virus (HCV) genotype (GT)1 to GT6-infected Asian participants with compensated cirrhosis with or without human immunodeficiency virus (HIV) co-infection who are HCV treatment-naïve or treatment-experienced with interferon (IFN) (alpha, beta or pegylated interferon [pegIFN]) with or without ribavirin (RBV) OR sofosbuvir with RBV with or without IFN.
The main purpose of this pilot study is to investigate the safety, effectiveness and tolerability of the study medication in the treatment of people with chronic hepatitis C virus infection who regularly attend a psychiatrist-staffed clinic for opiate addiction treatment.
The Rapid-EC pilot study will determine feasibility of providing rapid point-of-care (POC) testing for HCV in community clinics, and whether the availability of POC testing increases uptake of testing, engagement in care and completion of treatment among people who inject drugs. The POC tests being utilised in this study are the OraQuick mouth swab test for the presence of HCV antibodies, and the Xpert HCV RNA viral load test using serum.
Several factors are barriers to effective Hepatitis C care: 1) The majority of Hepatitis C Virus (HCV)-positive patients (45-85 percent) are unaware that they are infected; 2) Only a small minority of those in need of treatment receive it; 3) Members of minorities and older patients are even less likely to receive needed care; and 4) Until recently, even those who were treated had a low chance of clearing the virus or achieving cure; 5) It is possible that older attitudes and expectation of futility might continue to persist among patients and provider in primary care settings. Community Health Centers are often the most culturally appropriate and accessible choices, particularly for underserved populations, with the benefit of ongoing trust and relationships with patients. Therefore, these can be ideal places to deliver complex HCV care if they possess the needed expertise. However, most community-based primary care and community health centers lack access to Hepatitis C evaluation and treatment services, leading to a major public health problem. Thus, investigators propose to implement and evaluate a pragmatic trial to implement and evaluate a multi-disciplinary model for HCV treatment at Currently, the treatment initiation rates at each of these sites is estimated as less than 10%. The investigators hypothesize that our project will increase the rate of participation in all the steps of the HCV care cascade and ultimately lead to more than doubled rates of treatment uptake
