Peg interferon and ribavirin currently represent the standard approved association for treating patients infected with hepatitis C virus (HCV) . The adjunction of amantadine is expected to gain about 10 % of sustained virological response (SVR) . Unfortunately, about 50 % of the patients remain relapsers or virological non responders. The main predictive factors of SVR are HCV genotype and body weight (BW). The impact of the drug pharmacological properties, particularly those of ribavirin requires complementary studies. This drug has a large distribution volume and its concentrations display large inter-individual variability. Two studies performed in HCV patients found no correlation between ribavirin dose adjusted on BW and a single ribavirin time point serum concentration at steady state. The aim of this study is to investigate the pharmacokinetic-pharmacodynamic relationships of ribavirin in hepatitis C patient

NCT01340573
This is a non-interventional study designed to evaluate the efficacy and safety of combination study drugs in the treatment of participants diagnosed with Chronic Hepatitis C (CHC). CHC participants with confirmed positive hepatitis-C virus (HCV) RNA in plasma, and who have not been previously treated with the Pegylated interferon (PegIntron) Pen, were enrolled into study.
NCT06180590
Hepatitis C virus (HCV) infection remains a significant health problem in our country. The World Health Organization estimated that 71 million people worldwide had chronic HCV infection in 2015. And 399,000 people died from cirrhosis or primary hepatocellular carcinoma caused by HCV infection. In 2006, the positive rate of HCV antibody in the population aged 1-59 was 0.43%. Therefore, it was estimated that there were about 5.6 million HCV infected people in the general population, and about 10 million cases of HCV infected people in high-risk groups and high incidence areas. Universal genotype direct antiviral agent (DAA) is the preferred antiviral therapy for hepatitis C. Sofosbuvir/velpatasvir are direct antiviral agents for hepatitis C. The results of Asian clinical trials mainly in Chinese population showed that the sustained virologic response (SVR) rates of sofosbuvir/velpatasvir at 12 weeks in genotype 1a, 1b, 2, 3a, 3b and 6 were 100%, 100%, 100%, 95%, 76% and 99%, respectively. Limited data showed that the SVR rate of sofosbuvir/velpatasvir at 12 weeks was 96% in Chinese genotype 3b patients without cirrhosis and 50% in patients with cirrhosis. After standard antiviral therapy for hepatitis C, there are still some patients who cannot obtain SVR, and these patients are defined as DAA-experienced patients. The guidelines recommend that Sofosbuvir/Velpatasvir combined with ribavirin be used as salvage therapy for patients with DAA-experienced failure. Vosevi is a new generation of antiviral therapy for hepatitis C, which contains three components, (Sofosbuvir, Velpatasvir and Voxilaprevir. It was a salvage treatment plan for DAAs-experienced patients which was recommended by the Chinese hepatitis C prevention and treatment guidelines in 2019. However, there are insufficient data on the proportion of SVR acquired in Vosevi treated DAAs-experienced patients in Asian populations and the effectivity of antiviral therapy between Vosevi and Sofosbuvir/Velpatasvir combined with ribavirin. In the present study, the investigators enroll DAAs-experienced hepatitis C patients. The participants are randomly divided into two groups. Then the participants are treated with Vosevi or Sofosbuvir/Velpatasvir combined with ribavirin respectively. All enrolled participants are followed-up for 3 years. Objectives of the present study are as follows: A. To clarify the sustained virologic response rate after Vosevi therapy for DAAs-experienced patients. B. To clarify the safety and efficacy between the Vosevi therapy and the Sofosbuvir/Velpatasvir combined with ribavirin therapy. C. To clarify the changes of biochemistry indexes in DAAs-experienced patients after Vosevi therapy. D. To clarify the virological relapse rate at 12 weeks after Vosevi therapy. E. To clarify the rate of cirrhosis and liver cancer during the follow-up.
NCT01120795
The purpose of this study is to see if treatment of chronic hepatitis C in people who are on opiate replacement therapy such as methadone or buprenorphine (including patient who still inject drugs) is safe and effective.
NCT00882193
This is a non-randomized, open-label study examining the safety and efficacy of betaine in addition to standard anti-viral therapy in genotype 1 hepatitis C non-responders or relapsers to previous pegylated interferon plus ribavirin. Betaine (20 gm/day) in 2 divided doses will be added to Peginterferon alpha 2a (180 mcg) plus weight-based Ribavirin (1000 or 1200 mg/day, for body weight \< or \> 75 kg, respectively, for 48 weeks. Patients must be diagnosed with chronic hepatitis C, genotype I, and have undergone therapy for hepatitis C with pegylated interferon plus ribavirin. Subjects will be followed for safety, tolerability, hepatitis C viral response and the effect on interferon gene signaling in peripheral blood mononuclear cells during therapy.

NCT05895448
Direct antiviral therapy (standard of care) administered to chronic hepatitis C-infected patients, in two hepatology clinics, who had used intravenous drugs in the past 6 months of signing informed consent (IC). This cohort was compared to concurrently treated chronic hepatitis C patients who were not intravenous drug users, who signed IC in these same clinics. Follow-up expected two years after cure and relapse rates recorded. Primary end point was SVR rate and secondary end points included reinfection rates in follow-up period.
NCT02219490
The purpose of this study was to evaluate the effect of treatment with ABT-450 co-formulated with ritonavir and ABT-267 (ABT-450/r/ABT-267) and ABT-333; 3-DAA regimen, with or without ribavirin (RBV) in adults with chronic hepatitis C virus genotype 1 (HCV GT1) infection.
NCT01439776
Standard therapy for chronic hepatitis C virus (HCV) is (Peg/RBV) combination therapy obtaining sustained virologic response (SVR) in 77% of naïve patients with genotype 1-3 Studies rarely address the issues of improving host factors. The current study examines whether adding vitamin D with Peg/RBV, a potent immunomodulator, could improve viral response(SVR)compared to Peg/RBV.
NCT02545335
The aim of this study is to characterize neutrophil function in patients undergoing chronic hepatitis C triple therapy with protease inhibitors in comparison to dual therapy with peginterferon and ribavirin and with interferon free treatment regimen to thereby elucidate the possible mechanisms of protease-inhibitor associated infections.
NCT03993925
In the current era of highly effective direct acting antiviral (DAA) therapy, the remaining obstacles to elimination of chronic HCV infection are identification of the high-risk groups, linkage to continued care and prevention of re-infection. It is estimated that 70-80% of patients with chronic HCV are unaware of their infection. Besides, public health education is limited and most patients are not aware that the current standard-of-care is highly effective, well tolerated and no longer require weekly subcutaneous injections. From a survey in Hong Kong in 2014, among 234 newly diagnosed HCV patients, only 20% agreed to undergo treatment. There is no universal screening programme for chronic hepatitis C infection in Hong Kong. and known high-risk patients include people who inject drugs (PWID), persons with certain medical conditions including those on hemodialysis, HIV infected, those with prior transfusion or organ transplantation. In this study, the investigators plan to reach out to PWIDs, people with substance abuse or prison inmates to provide rapid point-of-care screening for chronic hepatitis C infection, and to provide linkage to care for those diagnosed with chronic hepatitis C.
NCT02167945
The purpose of this study was to evaluate the effect of treatment with ABT-450 co-formulated with ritonavir and ABT-267 (ABT-450/r/ABT-267) and ABT-333; 3-DAA regimen, with or without ribavirin (RBV) in adults with chronic hepatitis C virus genotype 1 (HCV GT1) infection.
NCT02333292
Objectives: 1) To evaluate la proportion of hepatitic C virus (HCV)-monoinfected patients who show sustained virologic response (SVR) to treatment including direct-acting antivirals (DAAs) in the clinical practice in clinical units that treat infectious diseases and 2) to determine the frequency of adverse events, including those that are severe and/or cause treatment interruption, in DAA-based therapy in this setting. Design: Multicentric, prospective post-authorised cohort study. Setting: Hospitals of the Hepatitis Study Group (GEHEP) of the Spanish Society of Infectious Diseases and Microbiology (SEIMC). Study population: HCV-monoinfected patients that initiate DAA-based treatment outside clinical trials. Variables: The primary efficacy outcome variable is the proportion of patients who reach undetectable HCV-RNA 12 weeks after the scheduled end of therapy (SVR12). The primary safety outcome variable is the percentage of subjects who discontinue therapy due to adverse events. Statistical analysis: A descriptive study will be performed, as well as a double sensibility analysis of the frequency of SVR12 using both an intention-to-treat and an on-treatment approach. Those variables that are associated with SVR12 with a p-value \<0.2 will be included in a logistic regression analysis in which SVR12 will be the dependent variable.
NCT03483987
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.
NCT03693586
Chronic hepatitis C infection (CHC) is usually asymptomatic; nevertheless, there are studies that show that up to two thirds of patients may present some type of extrahepatic manifestation. The most frequent extrahepatic manifestation is type II mixed cryoglobulinemia (MCG-II) and clinically the most common presentation is leukocytoclastic vasculitis (LCV) with palpable purpura that affects the lower extremities. It is estimated that up to 80% of MCG-II cases are due to CHC. Also, previous studies have demonstrated that CHC prevalence is higher in patients with autoimmune diseases compared with general population. Therefore, if vasculitis is an extrahepatic manifestation of CHC, then the prevalence of CHC infection in this group of patients could be higher than the prevalence reported in general population. The aim of the study is to know the prevalence of CHC, determined by serological rapid test for hepatitis C screening, then all positive cases will be confirmed by quantitative viral load, in patients who consult primarily to a rheumatology department for "vasculitis" or other potential hepatitis C extrahepatic manifestations (rheumatological conditions).
