Active clinical trials for "Herpesviridae Infections"

This is a randomized, blinded, placebo-controlled, dose-ranging Phase 1b study of the safety, PK, and antiviral activity of ABI-H3733 in treatment-naïve or off-treatment chronic Hepatitis B virus (cHBV) subjects that are Hepatitis B e antigen (HBeAg) positive or negative. The study will enroll up to 5 sequential cohorts of 10 subjects each, for a total of up to 50 subjects, randomized 8:2 to receive ABI-H3733 or placebo.

The goals of therapy against chronic hepatitis B are to decrease the morbidity and mortality related to chronic HBV infection. Currently available antiviral therapy can suppress viral replication but only a small proportion attain functional cure, which is defined as HBV surface antigen-to-antibody seroconversion. Hepatitis B surface antigen (HBsAg) is a marker of persistent hepatitis B infection. It has been observed that patients who had both hepatitis B and hepatitis C, and who were treated for their hepatitis C with 12 weeks of ledipasvir/sofosbuvir for had a decline in HBsAg levels. This study hypothesizes that a similar decrease would be seen in mono-infected hepatitis B subjects over the course of 12 weeks treatment with ledipasvir/sofosbuvir.

To determine the safety and efficacy of oral valacyclovir hydrochloride ( 256U87 ) compared to acyclovir in the treatment of recurrent anogenital herpes in HIV-infected patients with CD4 counts = or > 100 cells/mm3.

The main purpose of this study is to evaluate efficacy of 24 weeks of study treatment, in terms of changes in hepatitis B surface antigen (HBsAg) levels.

Part 1 is a randomized, double-blind, placebo-controlled study. It will assess the safety, tolerability, and pharmacokinetics of single and multiple orally administered doses of EDP-514 in healthy adult subjects. Part 2 is randomized, double -blind, placebo-controlled study including subjects with Hepatitis B Virus. It will assess the safety, tolerability, pharmacokinetics and antiviral activity of 28 Days of orally administered doses of EDP-514 in nucleos(t)ide reverse transcriptase inhibitor (NUC)-Suppressed Patients with Chronic Hepatitis B Virus Infection

Eligible subjects will be randomized to receive VALTREX® tablet 1g or placebo once daily for 60 days in a two-way crossover study with a washout period of 7 days between treatment periods.

The purpose of this clinical research study is to learn if the study drug entecavir will prevent the recurrence of hepatitis B virus (HBV) in participants who receive an orthotopic liver transplant (OLT) due to HBV infection.

To describe the immunogenicity and safety of modified process hepatitis B vaccine administered to renal predialysis and dialysis patients

Hepatitis B virus infection is a common occurrence among patients with HIV. Effective vaccines are available, but there's some uncertainty regarding specific dosages, specially among those who have not responded to an initial vaccination. The purpose of this study is to determine the effectiveness of a simplified immunization schedule compared to a high-dose one.

A 4-armed cluster randomised controlled trial conducted among secondary schoolgirls in Siaya, western Kenya, where clusters are the unit of allocation and schoolgirls the unit of measurement. The overall aim of the trial is to inform evidence-based policy to develop intervention programmes which improve adolescent girls' health, school equity and life-chances. The primary objective is to determine the impact of menstrual cups or cash transfer alone, or in combination, compared against controls, on a composite of deleterious outcomes (HIV, HSV-2 infection, and school dropout) over 3 schoolyears follow-up.
