Active clinical trials for "Hepatitis B"

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 consists of Part A and Part B. Part A is a multi-center, randomized, double-blind, placebo-controlled clinical study to assess the safety, efficacy, PK and immunogenicity of RBD1016 injection combined with NAs in CHB participants. Part B is a multi-center, open clinical study to assess the safety, efficacy, PK and immunogenicity of RBD1016 injection combined with PegIFN-α and NAs in CHB participants.

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.

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.

This study was a randomized, double-blind, placebo-controlled, entecavir basic treatment, multicentre clinical study. The main objective of this study was to confirm the efficacy and safety of hydronidone in the treatment of chronic hepatitis B liver fibrosis.

Subjects can be classified into two groups, Group 1 include non-cirrhotic patients, Group 2 include cirrhotic patients. All the patients will be received prophylactically TAF for 4 weeks before using SOF/VEL once daily for 12 weeks. In total, Group 1 patients will be discontinued TAF once daily therapy at the end of week 28 if no HBV reactivation occurs during treatment , Group 2 patients will be received TAF once daily for 64 weeks. In this study, after week 64, Group 2 patients will continue NUC treatment but pay by themselves. For those who is GT3 cirrhosis patients, RBV added simultaneously with SOF/VEL for 12 weeks. For patients weighing < 75 kg, the dose is 500 mg twice; for patients weighing ≥ 75 kg, the dose is 600 mg twice.

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.

This is a Phase II study in patients with advanced liver cancer (hepatocellular carcinoma) as a result of hepatitis B and/or C infection. Participants will be dosed with either MTL-CEBPA (an experimental treatment) and sorafenib or sorafenib alone. The MTL-CEBPA is administered once every 3 weeks via intravenous infusion. Sorafenib is taken orally from Day 8 for the combination group or Day 1 for the sorafenib alone group at a dose of 400 mg twice a day. Participants will receive 3 week cycles of treatment until disease progression, unacceptable toxicity, withdrawal of consent or death occurs. The combination of MTL-CEBA and sorafenib combination of treatment was tested in a previous Phase I study (OUTREACH) which showed anti-tumour activity along with a good safety and toxicity profile.

The main goal of therapy for patients with chronic HBV infection with no significant liver disease is to improve survival and quality of life by preventing disease progression, development of liver cirrhosis and consequently HCC development. The likelihood of achieving these goals depends on the timing of therapy during the natural course of the infection but also on the stage of the disease and the patients' age when treatment is started. The inhibition of viral replication and normalization of ALT by antiviral treatment has been shown to achieve the elimination of chronic HBV-induced necroinflammatory activity and progressive fibrotic liver progression in the vast majority of patients, in turn reducing the risk of HCC. Even in HBeAg positive patients, treatment-induced HBeAg loss and seroconversion to antiHBe characterizes the induction of a partial immune control often leading to a low replicative phase of the chronic HBV infection and good outcomes. Treatment in chronic HBV infection is indicated in - presence of advanced fibrosis/cirrhosis (LSM >11 KPA) or patients with significant fibrosis (LSM >8 or APRI >1.5 or >F2 on liver biopsy) with high viral load (>2000 IU/ml) or significantly elevated ALT (x2 ULN). Presence of any of these factors is known to increase the risk of development of cirrhosis and hepatocellular carcinoma. TAF in non-cirrhotic patients (LSM <8 KPA) with normal ALT and low viral load (HBV DNA <2000 IU/ml) (currently treatment ineligible) as compared to delayed initiation (on demand) might reduce HCC risk, progression of liver fibrosis and reduction in HBsAg levels. As TAF is known to have favorable effects on the overall long-term outcome, the main clinical challenge is to identify the patients at risk of HCC and cirrhosis who warrant early antiviral therapy.
