To evaluate Sustained Virologic Response at post treatment Week 12 (SVR12)following treatment with Lambda/RBV/DCV in chronic HCV GT-1, -2, -3 or -4 subjects co-infected with HIV-1
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.

NCT00854087
Current treatment of chronic liver disease relies upon removing the primary insult to the liver (e.g., alcohol) or treating the underlying viral infection (HBV, HCV, etc.). However, in the case of hepatitis C, a significant number of individuals will not clear the virus with current approved standard antiviral therapy, leaving them no options to manage their hepatic fibrosis, which can progress to cirrhosis and ultimately hepatocellular carcinoma (HCC). Fuzheng Huayu has been used in numerous studies in China and has been found to have a satisfactory prophylaxis effect on the chronic liver injury and formed liver fibrosis in rats and humans. In addition, it enhances the degradation of liver fibrosis and protects hepatocytes from injury and death, manifesting as decreasing of ALT and AST, and enhancement of albumin level. In addition, preliminary studies indicate that the Fuzheng Huayu has a good safety and tolerability profile with promising efficacy. The number of patients failing Interferon based therapy (i.e. not achieving SVR) is increasing. There are no approved standard of care treatment options for this population nor for patients who are intolerant or unwilling to receive Interferon; thus they are at higher risk for the progression of fibrosis. Moreover, there are no approved therapies to treat hepatic fibrosis, but basic research is exploring the pathophysiological mechanisms. Fuzheng Huayu is easy to administer, with a good safety and efficacy profile against fibrosis. Therefore, the investigators propose to further study the safety and efficacy profile of Fuzheng Huayu in a randomized, placebo-controlled, double blind study in Chronic Hepatitis C patients with hepatic fibrosis who have failed prior anti-HCV therapy or are intolerant or refuse Interferon based therapy. The primary objective of this study is to establish the safety and efficacy of Fuzheng Huayu treatment in chronic hepatitis C subjects who have failed prior anti-HCV therapy or cannot receive or refused Interferon based therapy in improving liver fibrosis.

This study will contain 2 parts. Part 1: Approximately 20 participants and at least 10 of the 20 participants previously treated with the combination of ombitasvir/paritaprevir/ritonavir and dasabuvir, with or without RBV, and experienced treatment failure. Part 2: Approximately 10 participants and all participants previously treated with SOF/ledipasvir and experienced treatment failure.
NCT01782495
The purpose of this study is to evaluate the safety and efficacy of ABT-450/r/ABT-267 with or without ABT-333 and with or without ribavirin (RBV) in adult liver or renal transplant recipients with hepatitis C virus (HCV) genotype 1 or 4 (GT1 or GT4) infection.
NCT02932293
There is only one kind of treatment (simeprevir 150 mg + sofosbuvir 400 mg+daclatasvir 60 mg) in this study but the treatment duration may be different depending on patients' response to the antiviral therapy and whether patients have liver cirrhosis. If patients have no cirrhosis and the HCV viral load on day 2 is \<500 IU/ml, patients will receive sofosbuvir, daclatasvir and simeprevir for 3 weeks, otherwise the treatment duration is 4 weeks. If patients have cirrhosis and the HCV viral load on day 2 is \<500 IU/ml, patients will receive sofosbuvir, daclatasvir and simeprevir for 6 weeks, otherwise the treatment duration will be 8 weeks.
NCT02972723
Hepatitis C virus infection (HCV) is a major cause of cirrhosis and death from liver disease worldwide. Current therapy for HCV with interferon based therapies results in cure rates of around 5055% which leaves a significant number of patients without effective therapy. HCV induces (can bring on) insulin resistance and insulin resistance is a factor known to reduce the response to antiHCV therapy. This finding stimulated initial studies looking at agents that may reduce insulin resistance as additional therapy in HCV infection. A study using metformin in addition to interferon and ribavirin showed a nonsignificant increase in cure rates (53% vs. 42%), but this was limited to patients with type 1 infection AND demonstrable insulin resistance. The assumption was made that the potential effect of metformin was likely to be on insulin resistance and thus by modulating this enhances response. The investigators (Prof M Harris, University of Leeds) have data (currently unpublished)suggesting that metformin may have an antiviral effect independent of its effect on insulin resistance, thus raising the possibility that metformin may have a direct antiviral effect in vivo. Given that the development of specific antiHCV agents which target viral proteins such as its polymerase and protease are in trial development but have so far proved either highly toxic or are likely to have a huge cost there is considerable rationale for looking at alternative potential antiHCV agents and in this context metformin is cheap, readily available and has an excellent safety profile. This pilot study therefore addresses the question "Does metformin therapy result in a significant drop in HCV viral load in chronically infected patients?"

NCT00682591
Prospective, longitudinal multi-center study performed in 15 participating substitution centers in Germany. Aims: \- Primary objective: To compare the impact of the different substitution drugs (methadone, buprenorphine, and suboxone) on the neurocognitive, emotional, and quality-of-life-related tolerability in opioid dependent patients under HCV treatment. \- Secondary objective: To investigate if IFN therapy impairs efficacy (with respect to e.g. retention rates, concomitant drug use and in particular neurocognitive function) and tolerability of agonist maintenance treatment with methadone, buprenorphine, or suboxone
