Filter by:- Herpesvirus infections may be severe in immunocompromised patients, with a high risk of complications and mortality. - Recipients of hematopoietic stem cell transplant (HSCT) or patients receiving high-intensity chemotherapy for hematological malignancies are the most vulnerable individuals. - Although the worldwide prevalence of herpes simplex virus 1 (HSV-1) and varicella-zoster virus (VZV), antiviral prophylaxis in seropositive HSCT recipients has significantly reduced the rate of infection. - Acyclovir (ACV) is the first-choice drug for the prophylaxis or the therapy of that kind of infection. - Since the beginning, ACV has demonstrated to be characterized by a large interpatient variability, especially in children. - Therefore, therapeutic drug monitoring and pharmacokinetic studies may help in optimizing drug in children with malignancies.
The purpose of this study is to evaluate the efficacy of the study intervention based on hepatitis B surface antigen (HBsAg) levels.
In order to tackle the unmet needs in chronic HBV infection, a consortium of clinical partners has gathered to establish a registry for patients with hepatitis B mono- and co-infections. The partners will build up a European-wide registry to be able to stratify patients for upcoming clinical trials. Extensive analyses of virus and host-specific parameters are to be carried out from these patients. The knowledge gained thereby should contribute to a better understanding of the HBV control and enable patient stratification with regard to immunomodulatory therapies. Furthermore, hepatitis B patients are to be identified who are willing to participate in future studies to investigate immunotherapies to cure HBV infections (e.g. therapeutic vaccines).
The purpose of this study is to evaluate the efficacy in terms of hepatitis B surface antigen (HBsAg) changes from baseline for the treatment regimens of 24 weeks of JNJ-73763989 + 24 weeks of nucleos(t)ide analog (NA) + 12 or 24 weeks of pegylated interferon alpha-2a (PegIFN-alpha-2a) (with immediate or delayed start of PegIFN-alpha-2a treatment).
Part 1 is a randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability, and pharmacokinetics of single and multiple ascending doses of EDP-721 in healthy subjects. Part 2 is a randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability, pharmacokinetics and antiviral activity of EDP-721 in combination with EDP-514 in patients with chronic hepatitis B virus infection.
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
This is a randomized, double-blinded, placebo-controlled, multi center, dose ranging study of safety and efficacy in both volunteers with chronic hepatitis B virus infection and in volunteers with hepatitis D virus coinfection. Volunteers will be administered multiple oral doses of ATI-2173 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.
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.
The purpose of this study is to evaluate the efficacy in terms of hepatitis B surface antigen (HBsAg) levels of the study intervention (that is, JNJ-73763989 + JNJ-56136379 + nucleos[t]ide analog [NA] and pegylated interferon alpha-2a [PegIFN-alpha2a]).
The purpose of this study is to assess changes in intrahepatic hepatitis B surface antigen (HBsAg) between baseline and on-treatment liver biopsy in response to JNJ-3989-based combination treatment.
