Filter by:This is a phase 2 study in which participants with chronic hepatitis B virus (HBV) infection will receive VIR-2218, VIR-3434 and/or PEG-IFNα and be assessed for safety, tolerability, and efficacy
Mother to Child transmission is the main route of hepatitis B virus (HBV) transmission in China, attributing to over 50% HBV infection. Familial aggregation in HBV infection is well recognized with underlying stipulations like mother-to-child transmission(MTCT), susceptible genes, close contact and other factors. Not surprisingly, a large proportion of hepatitis B virus infected population in China have a family history of hepatitis B virus infection. In clinical practice those family members usually undergo merely hepatitis B virus serology tests without HBV DNA test, which ruled out false HBsAg (-) or Occult HBV Infection (OBI) from Screening and linkage to care (SLTC). Unfortunately, the missed-out OBI in CHB family members was of a greater prevalence compared to those from general population (8.0% vs. 2.6%) . Moreover, OBI has been well recognized as strong risk factor in hepatocellular carcinoma (HCC) development with significant HBV DNA integration into host genome . In light of the latest 2019 China CHB guidelines, treatment criteria covered subjects with family history of CHB related cirrhosis or hepatocellular carcinoma(HCC). Therefore, subjects of HBsAg (+) with normal alanine aminotransferase(ALT) or OBI are eligible for further consideration of HBV anti-viral treatment. This study proposed will explore the prevalence of OBI in subjects with family history of HBV related cirrhosis or HCC. The screened HBsAg (+) with normal alanine aminotransferase(ALT) and OBI subjects would be linked to anti-viral therapies.
This is a phase three study to evaluate the safety and efficacy of Pradefovir treatment in chronic hepatitis B patients. Subject will be randomized to Pradefovir group and TDF group at a ratio of 2:1. Treatment duration will be 96w in randomization and followed by 48w in open. The interim analysis will be conducted when all subject completed the first 48-week treatment.
PD1 blockade has been approved as salvage therapy for advanced hepatocellular carcinoma (HCC). Although there is not solid evidence that PD1 blockade would induce hepatitis B virus (HBV) reactivation, previous clinical trials of PD1 blockade required enrolled patients to receive anti-HBV medications and control the viral load to be under 100-2000 IU/mL before initiation of PD1 blockade therapy. Such a requirement may not be necessary and could delay the treatment. Guidelines for prevention of chemotherapy induced HBV reactivation only suggest combining anti-HBV medications during the chemotherapy course without such a requirement of very load HBV viral load. The investigators hypothesized that under anti-HBV medications, patients with advanced HCC and active chronic hepatitis B virus (HBV) infection can receive durvalumab treatment without increased risks of HBV reactivation and related complications.
The purpose of this study is to evaluate the efficacy of 48-week study intervention with JNJ-73763989+JNJ-56136379+nucleos(t)ide analog (NA) regimen compared to NA alone assessed by HBsAg levels. This study is part of HepB Wings Platform Trial (PLATFORMPAHPB2001).
Herpes simplex virus (HSV) infection is very common, as most people will experience herpetic infection during their lifetime. The most common manifestation of HSV infection is sores which may appear at any age. No specific antiviral therapy is available to totally cure herpetic infections and today, there is no treatment that allows the definitive eradication of the virus. The 2LHERP® has been available for more than 20 years, and has received a marketing authorization in Belgium by the FAMHP. It is used as an immune regulator in the treatment of herpetic infections. Since 2LHERP® has been made available, clinical observational data collected on treated patients have shown the beneficial effect on the disappearance of herpetic recurrences. The purpose of this placebo-controlled trial is to evaluate the efficacy of 2LHERP® on the treatment of herpetic infections in adults.
China is a highly prevalent area of hepatitis B virus(HBV) infection, with at least 75 million hepatitis B virus carriers, and 80% of primary hepatocellular carcinoma (HCC) is associated with chronic hepatitis B virus infection. Liver transplantation is currently the preferred method for end-stage liver disease such as biliary atresia and cirrhosis in children. In recent years, children's liver transplantation has developed rapidly and the number of developments has increased significantly. If there is chronic hepatitis B virus infection in the donor liver, it may cause HBV transmission, or the patient may have a low-load occult hepatitis B virus infection, and after immunosuppressive treatment, it may lead to hepatitis B virus infection after surgery.
Hepatitis B virus (HBV) infection is a major public health problem facing the world, with more than 2 billion people infected with HBV. There are more than 400 million chronic carriers, and 75% of carriers live in the Asia Pacific region. The mother-to-child transmission route of hepatitis B virus is recognized as one of the most important routes of transmission, and recent studies have found that fathers who are carriers of HBV may also be one of the risk factors for HBV infection in children, but as far as the investigators know. Therefore, as a high-population area in China, the purpose of this study is to investigate the prevalence of HBV infection in this population.
To investigate the efficacy of using antiviral therapy in third trimester of pregnancy to reduce mother-to-infant HBV transmission, and to access the safety of such treatment for mothers and infants.
Children with clinically diagnosed leukemia may experience occult HBV infection after chemotherapy immunosuppressive therapy, which may affect the normal course of leukemia treatment. However, this is not caused by clinically relevant diagnosis and treatment measures but exists in vivo.
