Active clinical trials for "Hepatitis A"

The primary objective of this study is to characterize the long term (ie, 96 weeks of follow up) bone safety profile of open-label tenofovir disoproxil fumarate (tenofovir DF) treatment in CHB-infected adolescents. This includes prospectively evaluating and comparing the bone mineral density (BMD) change between CHB-infected adolescents 12 to < 18 years of age treated with tenofovir DF in European treatment centers who are assigned to one of two schedules for renal and bone laboratory monitoring and BMD measurement.

Follow-up for viral activity, changes in liver function and safety in patients with no SVR24 in feeder studies

Achieve sustained virologic response (SVR) in patients infected with HCV genotype 1, cirrhosis, and early clinical decompensation using 12 weeks of Olysio/Sovaldi/Ribavirin (or known as: Simeprevir(SMV)/Sofosbuvir(SOF)/Ribavirin (RBV). Hepatic improvement during and after Simeprevir(SMV)/Sofosbuvir(SOF)/Ribavirin(RBV) treatment using a new test of liver function, HepQuant-SHUNT.

The main purpose of this study is to evaluate the durability of Sustained virologic response (SVR) in participants who achieved SVR at last post-therapy visit of parent studies (LPVPS) with NCT Numbers NCT02569710 and NCT02765490.

The purpose of this study is to evaluate the effect of PEGASYS® (peginterferon alfa-2a 40KD) plus Robatrol® (ribavirin) combination therapy given for 36 weeks versus 48 weeks on the clearance of HCV viremia 24 weeks after treatment end

This study will examine whether 12 month treatment with entecavir(Baraclude®) has an effect on changes of liver stiffness measurement (LSM) and of hyaluronan measurement in patients with chronic hepatitis B infection.

The purpose of this study is to assess whether two higher doses (280mg or 420mg three times daily)of silymarin therapy are safe and tolerable, and shorten the illness in patients with acute viral hepatitis compared to placebo.

The main purpose of this study was to evaluate the safety and immunogenicity of Immunogenicity of Inactivated and Live Attenuated Hepatitis A Vaccines for healthy Chinese people.

This randomized controlled trial was implemented to evaluate the effect of integrating rapid Hepatitis C (HCV) testing into a pre-existing screening program for Human Immunodeficiency Virus (HIV) on HIV test acceptance and diagnosis of both HCV and HIV. A sample of 478 adults in a New York City Emergency Department participated in the study. Participants were randomized to receive either an offer of bundled HIV/HCV testing or HIV testing alone. Public Health Advocates approached eligible patients in the Emergency Department, performed HIV and HCV raid testing, and delivered test results to participants with post-test counseling. The primary outcome, HIV test acceptance, was compared between the two groups to evaluate whether the addition of an HCV test adversely impacted participants' consent to test for HIV. Questionnaires were also distributed to participants to assess HCV knowledge.

Mother-to-child transmission (MTCT) of hepatitis B virus (HBV) remains the major mode of transmission in most high and intermediate HBV endemic areas, despite existing WHO immunoprophylaxis recommendations. This immunoprophylaxis regimen, if given optimally, can prevent 75-80% of HBV MTCT, but optimal implementation is difficult because it requires administering monovalent HBV vaccine and hepatitis B immunoglobulin (HBIg) within 24 hours of birth. Due to the barriers of giving HBIg, the World Health Organization (WHO) states, "…owing to concerns related to supply, safety and cost, the use of HBIg is not feasible in most settings." Clearly, global control of HBV transmission will require improved MTCT prevention. Therefore, the investigators hypothesize that treating HBV early in pregnancy will lead to undetectable HBV DNA levels at delivery and prevention of MTCT of HBV without HBIg; a concept that has already been proven with HIV. Tenofovir disoproxil fumarate (TDF), an approved anti-HBV drug, is promising to prevent MTCT of HBV due to its high potency against hepatitis B and its safety record in pregnant women. A randomized, controlled clinical trial (RCT) will be necessary to determine if TDF given to HBV-infected pregnant women early in pregnancy plus vaccine to the newborn can decrease MTCT of HBV without HBIg. However, before embarking on a RCT, several critical knowledge gaps need to be addressed including the ideal timing for TDF initiation. The purpose of this proposal is to address these knowledge gaps.
