NCT03063723
Recently,surprisingly and unexpectedly increased aggressiveness and high rates of HCC recurrence (28%(16/58) and 29%(17/59), respectively) have been reported in patients who cleared HCV with DAAs after achieving a complete response to resection or local ablation within only 6 months of therapy. The authors hypothesized that the rapid eradication of HCV and control of liver inflammation would impact anti-tumoral immune control, which in turn might contribute to the neoplastic cells proliferation. Conversely, three independent prospective French cohorts failed to reveal an increased risk of HCC recurrence after DAAs treatment in CHC patients after receiving curative cancer treatments.Although the impact of DAAs treatment on the rate of HCC occurrence or recurrence still remain unclear, it would be more important to pay attention to the immunological changes of CHC patients treated with DAAs.Up to now, little was known about the immunological changes of chronic hepatitis C (CHC) patients treated with direct-acting antiviral agents (DAAs), here we try to explore the effect of antiviral treatment of CHC patients with DAAs on the frequency of monocytes, NK cells and cytokines that promote their activation.
NCT03062813
This study was to evaluate the efficacy and safety of Tacrolimus combined with entecavir antiviral therapy for HBV-associated glomerulonephritis in china. Tacrolimus combined with entecavir rapidly and effectively induced remission of HBV-GN in Chinese adults. Meanwhile, Tacrolimus may have a synergistic antiviral effect with entecavir. The study protocol was reviewed and approved by Guangdong General Hospital's Ethic Committee, and all participants provided written informed consents. The study will be a prospective, randomized,controlled,single-blind, multi-centre, withdrawal study conducted by Guangdong general hospital, Guangdong Academy of Medical Sciences.there will be two phases, phase 1, Screening and enrolling 112 HBV-GN patients about one year,and phase 2, ongoing follow-up for 24 weeks.The data of all patients will be recorded in the HBV-GN electronic database.Before the randomisation, All patients will receive entecavir routine antiviral therapy for two weeks.And then they will be randomized to two different group,the treatment group: Tacrolimus combined with entecavir antiviral therapy,the control group: The Tacrolimus placebo and entecavir antiviral therapy. The Tacrolimus target trough concentration was 5-10 ng/mL during the therapy. The primary outcome variables were the number of patients who reached complete or partial remission (CR or PR) after the 25 week-treatment. CR was defined as \<0.3 g/24 h proteinuria (UPCR\<300mg/g.cr) or lower plus stable renal function (eGFR\>50 ml/min/1.73 m2) and PR as proteinuria 0.3-3.0 g/24 h (UPCR 300-3000mg/g.cr) and 50% lower than baseline proteinuria plus stable renal function. Secondary outcome variables: 1) The number of patients who reached complete or partial remission (CR or PR) after the 13 week-treatment. 2) Serum creatinine (SCr) increased 2 times the baseline levels or 50% lower than the baseline eGFR(according to chronic kidney disease-EPI (CKD-EPI) )after the 25 week-treatment. 3)Serum HBV DNA was undetectable(HBV DNA\<500copies/ml) at the end of 25 week-treatment. 4) The number of patients who present acute kidney injury at the end of 25 week-treatment.

NCT02463331
The gold-standard treatment of Autoimmune hepatitis (AIH), with prednisone alone or in conjunction with azathioprine can reach resolution of the disease in 70-80% of the cases in US. However, in Brazil the response to these treatments seems to be worse, approximately 35% in five years. Because of the side effects of the gold-standard treatment and the need for an alternative option for the no responsive patients, news drugs must be evaluated for this proposal. Chloroquine diphosphate is an antimalarial drug that has been used for the treatment of rheumatological diseases for at the least five decades. Chloroquine was used as a single drug for up to two years for the maintenance of AIH remission in an open study. There was a 6.49 greater chance of relapse in the historical controls when compared with patients treated with chloroquine (72.2% x 23.5%; p = 0.031). The aim of this study was to investigate whether chloroquine in conjunction with prednisone can be used as an alternative treatment of AIH in a randomized study, and to evaluate its side effects.
NCT02612506
To evaluate the safety and tolerability of Hepalatide(L47) and characterize the clinical pharmacokinetics in healthy volunteers.
NCT01470651
Fatigue is one of the most common side effects of the treatment of hepatitis C infection with pegylated interferon and ribavirin, and is a major cause of treatment discontinuation. Armodafinil is an FDA approved stimulant medication for the treatment of narcolepsy and shift-work sleep disorder. This is a randomized placebo controlled study to determine whether patients assigned to armodafinil have fewer missed doses, dose reductions or treatment discontinuation due to side effects in the first 12 weeks of treatment for hepatitis C infection than do placebo patients. Placebo patients are offered 14 weeks of open label armodafinil after Week 12.
NCT02032875
This trial was open to participants who had received a liver transplant or had cirrhosis due to chronic HCV. All subjects were treated with daclatasvir+sofosbuvir+ribavirin and were followed for 24 weeks post treatment. Under certain conditions, the treatment duration could have been extended for cirrhotic participants. The study tested the efficacy and safety of this combination for treatment of HCV in cirrhotic and post transplant patients.

NCT01888900
Background: \- Some people who have chronic hepatitis C do not respond to the usual treatment with peginterferon and ribavirin. New chronic hepatitis treatments are being developed that may work better for different people. The treatments will look at how specific genes interact with the drugs. Researchers want to see how well these new drugs work in people whose chronic hepatitis C has not responded or only partly responded to the usual treatment drugs. Objectives: \- To compare new treatments for people with chronic hepatitis C. Eligibility: \- Individuals at least 18 years of age who have chronic hepatitis C that has not responded to standard treatments. Design: * Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Liver scans and a biopsy will be taken before the start of treatment. * Participants will be separated into two groups. One group will have the new treatment drugs (assunaprevir and daclatasvir). The second group will have these two drugs as well as peginterferon and ribavirin. All participants will have an initial 4-day hospital stay with regular blood tests to see how the start of the treatment works. * The first group will take the new study drug tablets daily for 24 weeks. Those who do not respond to this treatment will also start to take peginterferon and ribavirin, and the treatment will continue for 24 weeks after starting the additional drugs. * The second group will take all four drugs according to the standard dosing schedule for 24 weeks. * Treatment will be monitored with frequent blood tests. Liver scans, biopsies, and other tests will be performed as directed by the study doctors. * Participants will have 24 weeks of regular followup visits.
NCT02597270
The purpose of this study is to describe the genetic diversity of Hepatitis C virus (HCV) NS3/4a protease and NS5A protein of HCV in participants with chronic disease naive-drug or previously failed to double therapy (Peg-interferon and Ribavirin) and to identify the frequency of natural polymorphisms in HCV NS3/4a protease and NS5A protein that are associated with direct-acting antivirals (DAAs)-resistance.
NCT03042481
Pegylated-interferon (Peg-IFN) α-2a, entecavir (ETV) and tenofovir disoproxil fumarate (TDF) are current recommended first-line antiviral therapies for chronic hepatitis B (CHB). Compared with Peg-IFN therapy, nucleot(s)ide analogue (NUC) therapy has the advantages of having a potent antiviral effect, and good tolerance without side effect. The long-term safety and efficacy of ETV and TDF therapy had also been identified. However, poor durability of the effectiveness after stopping NUC therapy are encountered in the majority of patients. Previous study identified a high HBV relapse rate of over 50% in HBeAg- positive CHB patients treated with lamivudine. A recent study investigating the post-treatment durability of ETV showed that higher to 45.3% of the HBeAg-negative CHB patients happened a clinical relapse within 1-year after stopping ETV therapy. TDF is another recommended first line NUC with high potency and high genetic barrier. Although the efficacy of long-term TDF therapy had been identified, there is lack of data regarding the off-therapy response in CHB patients with TDF therapy currently. Only a small scale of patients treated with TDF were included in a recent study investigating off-therapy relapse in non-cirrhotic HBeAg-negative CHB patients after greater than 4 years of NUC therapy. In addition, the factors associated with off-therapy response are also still uncertain. The investigators plan to enrolled 400 CHB patients who had received oral antiviral therapy ETV or TDF and achieved the Asia Pacific association of the study of liver (APASL) criteria of stopping NUC therapy. The aims of the study are to investigate the rate of HBV relapse including virological and clinical relapse in all and between patients with ETV and TDF therapy, and to identify the predictive factors of relapse.

NCT00362674
The purpose of this study is to evaluate the durability of antiviral activity in chronic hepatitis B patients who showed complete response in L-FMAU-301,L-FMAU-302 or L-FMAU-303 trial.
NCT01836718
The purpose of this study is to measure intrahepatic HCV RNA levels at the time of liver transplantation in patients receiving antiviral therapy while on the liver transplant waiting list. This will eventually be correlated with the degree of hepatic fibrosis present within different geographic sites in the cirrhotic liver. Tissue samples will be obtained from the patient's liver explant as well as hilar lymph nodes. Upon the removal of the cirrhotic liver at the time of transplantation, the explant will be biopsied multiple times in different segments of the liver and preserved for viral detection studies as well as analysis of the degree of fibrosis. Peripheral blood mononuclear cells (PBMCs) will be obtained for viral detection at the time of transplantation. Serum HCV RNA levels will also be obtained at 1 month, 3 months and 6 months post liver transplantation. Study Hypotheses: * Virological relapse or non-response is higher is patients with cirrhosis due to failure of antiviral medication to concentrate adequately in a fibrotic liver having an altered sinusoidal micro-architecture * HCV may persist in different geographic regions of the fibrotic liver in part predicated on blood supply to that area and this may have an effect on overall virological response. These differences in viral persistence and detection may exist in different lobes of the liver or even within a few centimeters within the same portion of the liver parenchyma. * PBMC and hilar lymph nodes may be extrahepatic reservoirs of HCV viral persistence in patients receiving antiviral therapy and may account for virological relapse post-therapy * There may be varying degrees of fibrosis within the same cirrhotic liver which may impact on hepatic synthetic function and antiviral response to treatment.
