Filter by:This is open-label, randomized, multicentre study to compare the efficacy and safety of the 8-week versus 12-week of SOF-RVD combination treatment for non-cirrhotic chronic hepatitis C patients. All the recruited subjects will receive the treatment accordingly and be followed up for 24 weeks following the completion of treatment.
This is a prospective, observational, open-label, pharmacokinetic study will evaluate PK of SOF/DAC in lactating HCV-infected females at weaning or women who voluntarily decided to forego breastfeeding to initiate HCV infection treatment. Therefore, drug concentrations can be determined in maternal plasma and milk without risk to the children. HCV infected women at weaning after various durations of breastfeeding and HCV infected women who wish to initiate treatment immediately after delivery and forego breastfeeding will be recruited to start treatment under the guidance of their physician with SOF/DAC to determine M/P ratios of each of SOF, GS-331007 and DAC.
Chronic hepatitis C virus (HCV) infection remains a health burden in people living with human immunodeficiency virus (HIV). Interferon (IFN)-based therapy is the treatment of choice for HCV infection for HIV coinfected patients in earlier years. However, the treatment responses are far from ideal and the treatment-emergent adverse events (AEs) are frequently encountered. Based on the excellent efficacy and safety, IFN-free direct acting antivirals (DAAs) have been the mainstay of therapy for HCV. Furthermore, the world health organization (WHO) has set the goal of global HCV elimination by 2030. The microelimination of HCV among HIV/HCV-coinfected patients is also listed as the prioritized target by WHO. Although the overall treatment response has improved dramatically during the past 5-10 years, several studies have indicated the HIV/HCV-coinfected patients had high risks of reinfection following successful antiviral treatment. The risk of HCV reinfection was reported to be 24.6% among HIV-positive men who have sex with men (MSM) in Austria, German, France and the United Kingdom who attained sustained virologic response (SVR) by IFN-based therapy. Two recent studies from Canada showed that the incidence of HCV reinfection in HIV-positive patients was higher that HIV-negative patients (3.44 vs. 1.13 per 100 person-year; 2.56 vs. 1.12 per 100 person-year). In Taiwan, 14.1% of the HIV-positive patients had HCV reinfection following treatment-induced or spontaneous viral clearance, resulting an incidence of 8.2 per 100 person-year with a total of 218.3 person-years of follow-up for these patients. Because data regarding to the HCV reinfection in HIV-positive patients are still limited, where a more comprehensive assessment of HCV reinfection is important based on the perspectives of HCV microelimination among HIV-positive patients in Taiwan, the investigators thus aim to conduct a long-term, large-scale cohort study to assess the risk of HCV reinfection in HIV-positive patients achieving SVR after IFN-based or IFN-free therapies, and to assess the factors associated with different risks of reinfection in these patients.
Among the hemodialysis units, the global incidence of HCV infection ranges from 1.2% to 2.9%. Data regarding the long-term risk of reinfection among hemodialysis patients achieving SVR are limited. To our best knowledge, only one study assessed the long-term negativity of serum HCV RNA in hemodialysis patients who achieved SVR after IFN-based therapies. With a median follow-up of 48 months following SVR, the life-time cumulative survival for HCV RNA negativity was 86% among the 121 participants who were on maintenance dialysis. Furthermore, the life-time cumulative survival for HCV RNA negativity was 95% among the 45 participants who underwent renal transplantation from HCV-negative donors. Because the literatures regarding the long-term follow-up of viral outcome, the patient numbers to be recruited are still limited, and all studies are focused on IFN-based treatment, we aim to assess the long-term risk of HCV reinfection in hemodialysis patients attaining SVR by IFN-based or IFN-free therapies.
The results of the GX device are equivalent to standard venous blood sampling. With this study we are going to determine the prevalence in drug users with difficult venous access. On the other hand, we want to look at the place this device can have in primary care.
The overarching goal of this study is to develop a peer-based care coordination intervention for individuals with 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.
This study is being done to compare two strategies to deliver HCV treatment to persons with hepatitis C virus (HCV) who also use drugs and are participating in an outpatient opioid treatment program (OTP). Participants will be randomized into one of two treatment groups: 1. Test and treat plus peer-mentors: This treatment group will be offered 8 weeks of glecaprevir/pibrentasvir (an FDA approved HCV treatment) within days of HCV diagnosis at the OTP. Participants in this group will receive treatment adherence support from a peer-mentor who is someone who has been cured of HCV infection. 2. Standard of care HCV treatment referral: This treatment group will be referred to an offsite HCV treatment location. This is the usual care for anyone who tests positive for HCV at the OTP who is not participating in this study.
The primary goal of hepatitis C virus (HCV) Direct Acting Antivirals (DAAs) is to achieve undetectable HCV RNA in the blood. A response that should be maintained for at least 12 weeks from completion of therapy. This is called sustained virological response (SVR) which corresponds to cure of HCV infection as risk of later relapse is very small. SVR is important to achieve improvement in liver necroinflammation and fibrosis and to decrease complications of cirrhosis. Failing to achieve SVR after treatment requires another regimen for these experienced patients. Real-world data are always needed to evaluate and improve our practices. Here investigators aim to assess tolerability and efficacy of different regimens used for management of genotype 4 HCV relapse.
Hepatitis C virus (HCV) disproportionally affects certain populations, including those facing substance use and mental health challenges. In the past, many individuals with mental illness were not treated due to the psychiatric side-effects of interferon. However, the development of highly effective, direct-acting antivirals (DAA) has revolutionized HCV treatment such that cure rates are >95% with 8-12 weeks of simple, safe, and well-tolerated therapy. A recent systematic review reported that across 13 North American studies, HCV prevalence among people admitted to psychiatric hospitals was a staggering 17.4% (13.2-22.6%). Despite these concerning figures, mental health facilities have not been a focus of HCV elimination efforts to date. The Centre for Addiction and Mental Health (CAMH) in Toronto is the largest mental health facility in Canada, with a psychiatric emergency department seeing ~35 patients per day with many admitted to the acute psychiatric units for safety and stabilization. Currently, psychiatric patients screened for HCV at CAMH have a 75% 'no show' rate at the Toronto Centre for Liver Disease (TCLD), which is located less than 5km away, suggesting that referral upon discharge is ineffective. This study will be the first trial to evaluate whether it would be feasible and beneficial to initiate treatment during an acute psychiatric admission rather than referring to specialty upon discharge. The combination of broad HCV screening with rapid linkage to treatment has led to successful elimination of HCV within defined populations, so-called micro-elimination. The investigators hypothesize that HCV treatment can be effectively delivered by providers in psychiatric care facilities, which will improve treatment uptake over traditional referral models.
Currently, there is a lack of literature on programs evaluating rapid screening methods to traditional venipuncture methods for sample collection during screening for viral hepatitis. Due to the relatively low diagnosis and linkage to care rate, screening programs that provide same day results for viral hepatitis infection may improve both diagnosis and enable providers to engage patients shortly after diagnosis. This stands in contrast to the multi-visit, weeks long process that normally accompanies serum testing for hepatitis C virus (HCV) and hepatitis B virus (HBV). A few American studies have examined the implementation of HCV inpatient screening programs; however, they are focused specifically on high-risk patient populations, the barriers to accessing care experienced by study participants are not relevant to the Canadian healthcare system context, and do not use rapid testing. Furthermore, there are few, if any, data on HBV inpatient screening programs and the diagnosis rate remains low. This project will provide key data on a rapid inpatient screening and linkage to care strategy as well as the prevalence of these viruses across different age bands within the population. Finally, the study will help determine whether rapid inpatient screening is a feasible and acceptable approach for screening and linkage to care.
