Filter by:The goal of this trial is to evaluate the performance of the Fujirebio INNOTEST® HCV Ab IV using simpler collection methods such as fingerstick and venous whole blood collection on dried blood spots (DBS). In order to assess performance in samples with high and low antibody titres, performance will be evaluated with undiluted samples of all trial participants and serial diluted samples for a subset of HCV antibody reactive samples. Serial dilution of reactive samples will provide further insights into the potential difference of sensitivity in samples collected on DBS versus plasma. Results of this trial will also support the update of the regulatory claims to include DBS as an alternative sample type.
The objective of this study is to determine the feasibility and acceptability of a peer recovery coach (PRC) intervention to improve linkage to hepatitis C (HCV) and/or human immunodeficiency virus (HIV) care, treatment initiation, and evaluation for HIV pre-exposure prophylaxis (PrEP) (when applicable) among individuals with a history of opioid use disorder accessing a substance use low-barrier-to-access (LBA) walk-in clinic. In-depth interviews will be administered to participants at baseline, three- and six-months for study participants (40 total participants). The investigator will also follow-up with the per recovery coach and administer surveys to assess the feasibility of a peer recovery coaching intervention in improving HCV/HIV related linkage to care and management. Patient medical records and peer recovery coach monthly reports will be accessed and reviewed to determine fidelity to research protocols.
This study has two parts. Part A will assess the safety, tolerability and pharmacokinetics (PK) of AT-777 in healthy subjects. Part B will assess the safety, antiviral activity/efficacy and PK of AT-777 in combination with AT-527 after 8 weeks of treatment in HCV-infected subjects.
The investigators propose to conduct a pilot randomized controlled trial comparing treatment as usual (TaU) for HCV screening (rapid anti-HCV screening and referral) to a intervention screening that includes TaU plus a rapid point-of-care HCV RNA test in persons experiencing homelessness. The primary outcome of interest is linkage-to-care. Linkage to care is defined as evaluation by a health care provider for HCV infection within 30 days of baseline screening and referral. We will compare the proportion of patients who are evaluated by a provider within the 30 day window in each study arm: (1) participants who screened positive with rapid anti-HCV and are referred for evaluation) and (2) Rapid HCV RNA plus TaU (those who tested positive with both rapid anti-HCV and confirmatory RNA and are also referred to a provider.) Secondarily, the investigators will also assess HCV RNA levels in both groups twelve weeks after treatment ends (24 to 36 weeks after anti-HCV screening) to determine the percent of individuals who achieved sustained virologic response (SVR12), which is a marker for cure.
This study is a two-way, non-interventional long-term dynamic follow-up clinical observational cohort study. In the Second Division of Liver Diseases, Beijing Ditan Hospital, Capital Medical University, chronic hepatitis C patients who were treated with interferon combined with ribavirin (PR) antiviral therapy (PR treatment for 6 months or more) and / or direct acting antivirals (DAAs ), and the baseline, antiviral treatment and discontinuation follow-up data of patients before antiviral treatment were collected, and follow-up observations of patients were carried out for every 3-6 months. The clinical data such as clinical biochemistry, HCV RNA and serological indicators (anti-HCV), AFP, and liver imaging (liver ultrasound) were collected during the study period. The virological response and clinical outcomes of chronic hepatitis C antiviral therapy were observed for at least 144 weeks. The incidence of liver cancer and decompensated liver cirrhosis after discontinuation of the drug was the main evaluation index. The aim is to explore long-term virological response and clinical outcomes, and elucidate its influencing factors.
The goal of this study is to effectively use a client-centered community-based intervention to engage people who inject drugs (PWIDs) in healthcare that helps reduce risky behaviors and lower infectious disease risks. Participants in the intervention group of this study will undergo a 12-week intensive multilevel harm reduction case-management intervention at three rural Vivent Health offices geared towards reducing human immunodeficiency virus (HIV), hepatitis C virus (HCV), and overdose risks in PWIDs. Prevention Navigators (PNs) at each office will help coordinate referrals to reduce substance use disorder and increase engagement in the substance use disorder care cascades. PNs will also engage participants in HIV, HCV, and sexually transmitted infections(STIs) care cascades.
The primary aim of this study is to calculate the incidence of HCV reinfection after successful DAA treatment among people who have recently injected drugs. The secondary aim is to identify factors associated with reinfection in this population. Individuals with active injecting drug abuse with a chronic HCV infection who have achieved end of treatment response (ETR; defined as non-detectable HCV RNA at end of treatment) to any interferon-free DAA combination will be included in this multicenter interventional study.
Multicenter, open-label, phase II safety and efficacy study of all-oral combination of narlaprevir/ritonavir and sofosbuvir in Treatment-naïve Patients with Chronic Hepatitis C Genotype 1.
Hepatitis C virus has been identified a quarter of a decade ago as a leading cause of chronic viral hepatitis that can lead to cirrhosis and hepatocellular carcinoma. Only a minority of patients can clear the virus spontaneously during acute infection. Elimination of HCV during acute infection correlates with a rapid induction of innate and a delayed induction of adaptive immune responses. The majority of patients is unable to clear the virus and develops viral persistence despite the ongoing innate and adaptive immune response. The virus usually develops several strategies to escape these immune responses.
Successful treatment of hepatitis C has been reported to be associated with 62-84% reduction in all-cause mortality (deaths), 68-79% reduction in risk of HCC and 90% reduction in risk of liver transplantation. The efficacy of NS5A inhibitors for the treatment of patients chronically infected with hepatitis C virus (HCV) can be affected by the presence of NS5A resistance-associated substitutions (RASs). Pre-existence of resistance associated substitutions (RASs) to direct antiviral agents (DAAs) reduces sustained virologic response (SVR) rates by 3-53% in hepatitis C virus (HCV) genotype 3 infected patients depending on different predictors and the DAA regimen used. This study will prospectively analyze data from the MukhMantri Punjab Hepatitis C Relief Fund (MMPHCRF) to determine the posttreatment prevalence of various NS5A RASs, and their effect on outcomes of treatment with daclatasvir-sofosbuvir or sofosbuvir-ledipasvirin patients with chronic HCV. The study aims to assess the prevalence and effect of RASs on sustained virological response (SVR) rates in patients with treatment failure to a regimen containing sofosbuvir and ledipasvir/daclatasvir.
