Active clinical trials for "Hepatitis A"

Hypothesis Combination of Boceprevir with Ribavirin in treatment-naïve patients with genotype 4 chronic hepatitis C infection will increase the proportion of patients achieving sustained viral response compared to standard treatment alone.

The study will assess the efficacy of PPI-668 (USAN: ravidasvir hydrochloride) in combination with sofosbuvir, with or without ribavirin, in the following Egyptian HCV gt-4 patient populations: Treatment-naïve patients, with and without cirrhosis (Group 1) Previous non-responders to interferon-based therapies, without cirrhosis (Group 2) Previous non-responders to interferon-based therapies, with cirrhosis (Group 3)

The purpose of this study is to evaluate the immunogenicity and safety of two doses of GSK Biologicals' HPV-16/18 L1 VLP AS04 vaccine when co-administered with GSK Biologicals' HAV vaccine according to 0, 6 month schedule, compared to the administration of either of these vaccines alone. The study will ascertain that the immune responses elicited to the two vaccines are not adversely impacted compared to when HPV-16/18 L1 VLP AS04 vaccine and HAV vaccine are administered alone.

The purpose of the study is to determine how effective preemptive tenofovir therapy is in preventing the re-activation of Hepatitis B infection, in patients who are receiving rituximab-based chemotherapy for Non-Hodgkin's Lymphoma or CLL/SLL. The rate of re-activation will be compared between patients who receive preemptive tenofovir and patients who receive tenofovir as needed.

The purpose of this study is to assess the long-term persistence of immunity to hepatitis A and B in adults who were vaccinated 16-20 years earlier with the combined hepatitis A and hepatitis B vaccine, Twinrix.

Oral antiviral drugs which can be given to patients with HBeAg-positive chronic hepatitis B include Lamivudine, Clevudine, Adefovir, Telbivudine, Entecavir and Tenofovir. 2009 American Association for the Study of Liver Disease (AASLD) Treatment Guidelines and 2009 European association for the Study of the Liver (EASL) Treatment Guidelines recommend the administration of Entecavir or Tenofovir with high potency and low resistance. Lamivudine has low antiviral potency and high incidence of mutation in long-term administration compared to Entecavir or Tenofovir. Clevudine causes the elevated creatinine kinase (CK), side effects including myositis/myopathy and much mutation in the long-term administration. Globe study demonstrated Telbivudine had more excellent antiviral potency than Lamivudine, which was also comparable to or higher than Entecavir or Tenofovir. Nevertheless, the choice of treatment drugs can be limited due to the mutation rate of 25% for 2 years. However, the analysis of Globe study results showed that 2-year treatment progress was very good in patient who showed virologic response at 24 weeks after the initiation of treatment and that high antiviral potency and low mutation rate were observed when the Telbivudine roadmap strategy (in the event that virologic response is shown at 24 weeks, telbivudine monotherapy is maintained and in the event that virologic response is not shown, tenofovir add-on therapy is done) recently implemented and announced in 2011 Asian Pacific Association for the Study of the Liver (APASL) was applied. However, the study was single arm study, which restricted the comparison between Entecavir and Tenofovir monotherapy groups. Therefore, this study intends to compare the anti-viral effect and mutation rate between Entecavir 0.5mg monotherapy group and Telbivudine roadmap strategy group in patients with HBeAg-positive chronic hepatitis B through a randomized study.

The purpose of the study is to investigate the long-term safety and the antiviral activity of the optimal doses of LB80380 for additional 48 weeks in treatment-naive patients with chronic hepatitis B infection compared to entecavir 0.5 mg.

The outcome of treatment of chronic hepatitis B is determined by viral and host interaction, thus the combination therapy of immunomodulator (PEG-IFN) and potent antiviral drug (entecavir) should improve the response rate. In addition, the simultaneous assessment of viral and host genetic factors associated with SVR may help to identify predictors of treatment outcomes, which will in turn significant reduce the cost/effect of therapy

This observational long-term follow-up study will assess the persistence of direct acting antiviral (DAA) resistant mutations and the durability of sustained virological response in patients with chronic hepatitis C who have participated in a Roche DAA treatment protocol. Up to 5 scheduled monitoring visits for blood sampling during an observational period of up to 36 months.
