Filter by: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.
The study is looking at the potential of utilizing a "point of care" test and treat pathway; using the DDA called Zepatier for achieving SVR in an homeless population who have tested positive for genotype 1 or 4 HCV.
Grazoprevir/elbasvir combination therapy is highly effective in the treatment of genotype 1b chronic hepatitis C, and the drug-drug interaction with central immunosuppressant, such as tacrolimus, should be manageable. The aim of this study is to assess the efficacy and tolerability of grazoprevir/elbasvir combination therapy in treating genotype 1b chronic hepatitis C after liver or kidney transplantation.
Study is a non-interventional, prospective, multicenter post marketing surveillance study to determine the safety of daclatasvir based therapy
The purpose of this study is to evaluate daclatasvir in combination with sofosbuvir given to children with chronic hepatitis C infection
HCV infection is treated with oral drugs, termed as 'direct-acting anti-viral agents' (DAAs). In India, four DAAs are available (sofosbuvir [SOF], daclatasvir [DCV], ledipasvir [LDV] and velpatasvir [VEL]). Globally, DAA based regimens have obtained excellent rates of cure. Cure of HCV infection is defined as undetectable HCV RNA 12 weeks after stopping drugs, also referred to as sustained virological response at week 12 (SVR12). Using these DAA based treatment regimens, a small number (up to 5%) of people fail to achieve SVR12 and HCV RNA reappear after a few weeks of stopping the drugs (virological relapse). Data on management of virological relapse are extremely limited, especially in genotype 3, and no guidelines exist regarding re-treatment options for such group. Hence, we plan to re-treat such people using what appear to be the best combination treatment in each situation and to review our experience over time. Participants with chronic HCV infection who relapsed following standard DAA-based treatment regimen will be invited to participate. We propose to re-treat them with the anti-HCV drug combination which appears to be the most suited to his/her clinical profile, based on the current empiric knowledge - the choice of drugs will be based on HCV genotype, the previous treatment regimen and the presence/absence of liver cirrhosis, etc. During anti-HCV treatment, participants will be given expected standard of care and HCV RNA will be tested at 4-week intervals starting from week 4 and till RNA becomes undetectable, and then at the end of treatment and 12 weeks after the treatment was stopped - as is the usual practice during such treatment. Relevant clinical, laboratory and treatment details will be recorded in a pre-defined data collection form. Treatment outcome will be categorized as success (SVR12), treatment failure (any detectable HCV RNA at the end of 24 weeks treatment duration) or relapse (HCV RNA negative at the end of treatment, but positive at 12 weeks after stopping treatment). If possible, a 5-ml blood specimen will be collected before starting re-treatment from all participants; in addition, another similar specimen will be collected following the treatment in those in whom the re-treatment is unsuccessful. These will be stored and may be used in future for virological studies to look for drug-resistance variations.
The purpose of this study is to evaluate whether treatment with Epclusa (sofosbuvir/velpatasvir) after lung transplantation in individuals with chronic hepatitis C infection is feasible, safe and effective at curing HCV.
This is a 1:1 randomized double-blind Placebo-controlled moncenter Phase IV study to investigate whether a successful interferon-free treatment of HCV-infection with ombitasvir/paritaprevir/ritonavir (OBV/PTV/r) in combination with dasabuvir (DSV) improves the patients' attention ability as compared to placebo as measured with the Att Test Sum Score change from baseline to week 12. A total of 30 patients with non-cirrhotic genotype 1b HCV infection will be randomly assigned to receive 12 weeks verum followed by 12 weeks Placebo (arm A) versus 12 weeks Placebo followed by 12 weeks verum (arm B). Patients will be followed up for 48 weeks.
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.
This multicenter, open-label, uncontrolled study will evaluate the efficacy and safety of increasing the dose of peginterferon alfa-2a (Pegasys) in participants with Genotype 1/4/5/6 CHC and an early non-response to a standard course of peginterferon alfa-2a plus ribavirin. The study will consist of screening (4 weeks), treatment (32 weeks), and follow-up (24 weeks).
