Filter by:This trial is linked to a largescale observational study determining the efficacy of sofosbuvir/daclatasvir in people in Pakistan (involving a separate protocol). The observational study will identify a cohort of patients who have not responded to first-line antiviral therapy (sofosbuvir plus daclatasvir) and the optimal treatment for these patients is unclear. This trial will address this issue by comparing two second-line treatment regimens to determine the preferred treatment option.
The National Australian HCV Point-of-Care Testing Program will establish an observational cohort to evaluate whether scale-up of finger-stick point-of-care HCV testing increases diagnosis and treatment for HCV infection. Participants will be recruited from settings providing services to people with a risk factor for the acquisition of HCV infection (including drug treatment clinics, needle and syringe programs, homelessness settings, mental health services, prisons, and mobile outreach). All participants who undergo HCV point-of-care testing at the study site will be included in the data collection. Participants will not receive treatment as a part of this study. Participants who are HCV RNA positive will be linked to standard of care.
The study is designed to assess efficacy of a finitie treatment in Chronic Hepatitis B patients who had stable treatment of NAs for ≧ 2 years， which is compared hepalatide in combination with Pegylated Interferon + TAF with Pegylated Interferon +TAF. Subjects will be randomly assigned to the hepalatide or placebo groups , 15 subjects in each group . Subjects will receive hepalatide+Pegylated Interferon +TAF treatment for 48 weeks or placebo +PegylatedInterferon +TAF treatment for 48 weeks , Then, stopping all treatments and followed with further 24 weeks follow-up.
The purpose of the study is to characterize the pharmacokinetic (PK) profile of cetrelimab administered subcutaneous (SC) and optionally intravenous (IV) in chronic hepatitis B (CHB) participants.
This is a randomized, double-blinded, placebo-controlled, multi center, dose ranging study of safety and efficacy in volunteers with chronic hepatitis B virus infection. Volunteers will be administered multiple oral doses of ATI-2173 vebicorvir in combination with tenofovir disoproxil fumarate and assessed for safety and efficacy including blood tests to show how the body metabolizes and eliminates the investigational drug as well as how the drug effects the virus infection.
Open label, single arm, multi-center clinical trial of lonafarnib 50 mg QD plus ritonavir 200 mg QD, administered orally, over a 48-week treatment period, with a 24-week post-treatment follow-up period, in patients with chronic Hepatitis D Virusinfection. Objectives: To evaluate the safety and tolerability of once daily dosing of lonafarnib 50 mg with ritonavir 200 mg over a 48-week treatment period. To evaluate the effect of once daily dosing of lonafarnib 50 mg with ritonavir 200 mg over a 48-week treatment period with a 24-week post-treatment follow-up on HDV viral levels. Trial population: Up to 30 patients with chronic HDV infection with detectable HDV RNA and compensated liver disease.
Rationale: The combination of azathioprine and prednisone is the first-line treatment for autoimmune hepatitis (AIH), a chronic inflammatory disease of the liver. Complete biochemical remission (CR) is the first treatment goal in autoimmune hepatitis. CR is determined by AST and ALT and IgG within the reference range. CR is not reached in a substantial proportion of AIH patients: after one year 50%, after three years around 20% did not achieve CR. Without CR ongoing hepatitis leads to progression towards fibrosis and eventually (decompensated) cirrhosis. Not achieving CR is the most important risk factor for the need for liver transplantation or liver related death, independent of age and presence of cirrhosis. Tacrolimus (TAC) and mycophenolate mofetil (MMF) are frequently used to prevent rejection in kidney and liver transplant patients. In AIH patients with insufficient response or intolerance to first-line therapy in retrospective cohort studies with MMF 0-57% and with TAC 20-95% CR was reached. Objective: The aim of this study is to compare the effectiveness of TAC with MMF as a second line treatment for AIH. Proportion of patients with CR after 12 months of treatment will be the primary outcome parameter to determine effectivity. Study design: Randomized open-label two arm study. Patients will be randomized between treatment with TAC or MMF. Study population: Patients with AIH with an incomplete response (no CR) to first-line treatment are eligible for this study. Intervention: In the TAC group baseline treatment will be replaced by tacrolimus. In the MMF group baseline treatment will be replaced by MMF. The current dose of prednisolone, or at least 5 mg daily, will be continued in both arms. After achieving CR prednisolone will be tapered according to protocol. Main study parameters/endpoints: Difference in proportion of patients with CR at 12 months (normalization of ALT, AST and IgG) between the TAC and MMF treatment group. Secondary parameters: - Safety and tolerability of TAC and MMF treatments - Difference in proportion of patients with CR at 6 months (normalization of ALT, AST and IgG) between the TAC and MMF treatment group. - Difference in ALT, AST and IgG at 6 and 12 months versus baseline - Difference in fibrogenesis and fibrosis parameters between groups and before and after treatment - Difference in quality of life between groups and before and after treatment
The purpose of study is identifying the effectiveness of 'continuing medical education' (CME) to primary healthcare worker to improve knowledge about viral hepatitis B-C
To date, antiviral treatment is not recommended for chronic hepatitis B patients with a normal ALT level and low viremia. The strategy is to closely monitor the patients. However, evidence suggests that these group are at risk of gradual disease progression and development of hepatocellular carcinoma. Peginterferon eliminates the hepatitis B virus through immune regulation and induction of antiviral protein expression. For patients with low viral load, the clinical cure rate is potentially promising. In this study, we aim to investigate the efficacy and safety of peginterferon alpha-2b therapy in selected chronic hepatitis B patients with normal ALT level and low viremia. It is expected to obtain a satisfactory curative effect. Peginterferon is a marketed drug available in Chinese clinics with indications of anti-hepatitis B virus.
There are about 400 million chronic hepatitis B virus (HBV) infection patients worldwide, posing a serious threat to global public health security. In China, HBV infection occured mainly in the perinatal period or infants, and about 10% of patients in the immune tolerance stage spontaneously transit to the immune clearance stage every year and become HBeAg-negative chronic HBV infection, resulting in a significant increase in the number of inactive chronic hepatitis B (CHB) patients. In recent years, different guidelines have not reached consensus on the need to initiate antiviral therapy for inactive CHB patients: In the guidelines of Asian Pacific Association for The Study of Liver(APASL)-2015 and American Association for the Study of Liver Diseases(AASLD)-2018, antiviral therapy is generally not recommended for this group of patients, and regular outpatient follow-up is recommended. Guideline of European Association for the Study of the Liver(EASL)-2017 suggests that people with a family history of cirrhosis and liver cancer at this stage could be treated with antiviral therapy even if they did not meet the indications of antiviral therapy. According to Guidelines for the Prevention and Treatment of Chronic Hepatitis B (version 2019) of China, antiviral therapy is still recommended for some patients with inactive HBsAg carrier status who are HBV DNA positive and meet the treatment indications. Studies have shown that some patients in immune tolerance stage may enter the immune clearance stage and have hepatitis flare. Patients of inactive CHB have the potential to develop HBeAg-negative CHB, and studies of long-term follow-up in this population have indicated the risk of hepatocellular carcinoma. With the popularization of the concept of functional cure for chronic hepatitis B, more and more people with inactive CHB have a strong desire for treatment. In recent years, several studies have demonstrated that Pegylated-interferon therapy can achieve high functional cure rate in patients with inactive CHB. The purpose of this study is to establish a national multi-center, prospective real world study to compare the efficacy of different antiviral treatment regimens for patients with inactive CHB and seek for the factors of functional cure.
