Active clinical trials for "Hepatitis"

This is a phase 2 trial in which participants with chronic hepatitis D virus (HDV) infection will receive VIR-2218 and/or VIR-3434 and be assessed for safety, tolerability, and efficacy

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

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.

Hepatitis C virus (HCV) disproportionally affects certain populations, including those facing substance use and mental health challenges. In the past, many individuals with mental illness were not treated due to the psychiatric side-effects of interferon. However, the development of highly effective, direct-acting antivirals (DAA) has revolutionized HCV treatment such that cure rates are >95% with 8-12 weeks of simple, safe, and well-tolerated therapy. A recent systematic review reported that across 13 North American studies, HCV prevalence among people admitted to psychiatric hospitals was a staggering 17.4% (13.2-22.6%). Despite these concerning figures, mental health facilities have not been a focus of HCV elimination efforts to date. The Centre for Addiction and Mental Health (CAMH) in Toronto is the largest mental health facility in Canada, with a psychiatric emergency department seeing ~35 patients per day with many admitted to the acute psychiatric units for safety and stabilization. Currently, psychiatric patients screened for HCV at CAMH have a 75% 'no show' rate at the Toronto Centre for Liver Disease (TCLD), which is located less than 5km away, suggesting that referral upon discharge is ineffective. This study will be the first trial to evaluate whether it would be feasible and beneficial to initiate treatment during an acute psychiatric admission rather than referring to specialty upon discharge. The combination of broad HCV screening with rapid linkage to treatment has led to successful elimination of HCV within defined populations, so-called micro-elimination. The investigators hypothesize that HCV treatment can be effectively delivered by providers in psychiatric care facilities, which will improve treatment uptake over traditional referral models.

A Randomized Study of ALG-000184 Drug to Evaluate Safety, Tolerability, Pharmacokinetics and Pharmacodynamics After Single and Multiple Doses in Healthy Volunteers and CHB Subjects

The goals of this clinical study are to compare the effectiveness, safety and tolerability of study drug, tenofovir alafenamide (TAF), versus placebo in teens and children with CHB and to learn more about the dosing levels in children.

This study is to investigate the clinical efficacy of three types of nucleotide/nucleoside analogues in treatment of HBV-related acute-on-chronic liver failure.

The study aims to demonstrate that whether treatment of nucleoside （acid）analogues (NAs) plus pegylated interferon (Peg IFN) α-2b for those NAs treated, low level of HBsAg, hepatitis B related compensatory cirrhosis patients will result in higher HBsAg clearance rate and reduce the risk of liver cancer. The investigators plan to enroll about 84 hepatitis B related compensatory cirrhosis patients, who have received NAs treatment more than 1 year with the level of HBsAg <1000IU/ml. These participants will be devided into 2 groups. Group A will receive the treatment of NAs plus Peg IFNα-2b. Group B will be treated with NAs as before enrollment. The participants in both groups will be followed up for 96 weeks. The primary endpoint is to compare the clearance rate of HBsAg between two groups. The secondary endpoint includes: (1) comparing the incidence of liver cancer during the 96 weeks follow-up, (2) comparing adverse side effects between the 2 groups. (3) comparing the virological and biochemical responses between the 2 groups.

Treatment with Tenofovir Alafenamide(TAF) in Chronic Hepatitis B (CHB) patients classified as beyond treatment indication of current international guidelines (e.g. aged more than 40 years old and 4 ≤ log HBV-DNA IU/mL < 8) is expected to bring improvement in long-term clinical outcomes. This expected result may expand the treatment indications in patients with CHB based on age and HBV-DNA in contrast to current international guidelines of CHB.

Patients with chronic hepatitis B should maximize the inhibition of HBV replication, which could reduce the incidence of liver cancer and liver disease-related complications. However, after 96 weeks of treatment with the first-line drugs, entecavir or tenofovir disoproxil fumarate, a certain proportion of patients still had low levels of HBV replication. Tenofovir alafenamide fumarate is a newly marketed anti-hepatitis B drug that is currently considered to be non-inferior to tenofovir disoproxil fumarate and safer bone and renal effects. Therefore, this research was put forward to investigate whether tenofovir alafenamide fumarate replacement for hepatitis B had a higher virological response rate and safety in patients with low levels of virus after 48 weeks of treatment with entecavir and tenofovir disoproxil fumarate.
