Filter by:The treatment of choice for chronic hepatitis D is uncertain. The investigators hypothesize that pegylated interferon (IFN) alfa-2b in combination with ribavirin (RBV) may be effective in the treatment of chronic hepatitis D patients who are also infected by hepatitis B virus (HBV). The purpose of this study is to test this hypothesis. The investigators will use pegylated IFN alfa-2b in combination with RBV for the treatment of patients with dual chronic hepatitis D virus (HDV) and HBV infection. A 24-week course of combination therapy pegylated IFN+RBV will be used.
This study is designed to evaluate the safety and antiviral activity of tenofovir disoproxil fumarate (TDF, tenofovir DF) compared to adefovir dipivoxil (ADV) for the treatment of HBeAg-positive chronic hepatitis B. Participants will receive either TDF or the approved hepatitis B therapy ADV. After 48 weeks all participants will be switched to open-label TDF.
This research study is being conducted to compare the safety and effectiveness of the investigational medication, LdT (telbivudine) versus adefovir dipivoxil, a drug approved by the Food and Drug Administration (FDA) for the treatment of hepatitis B infection. The results for patients taking LdT will be compared to results for patients taking adefovir dipivoxil.
The purpose of this study is to determine the safety and acceptability of a vaginal microbicide in HIV uninfected sexually active women. Study hypothesis: The vaginal microbicide 1% tenofovir will be safe and well tolerated in HIV uninfected women who are in good general health.
The purpose of this clinical research study is to provide entecavir to subjects with chronic Hepatitis B infection who have failed or who have demonstrated intolerance of marketed therapies or for those in whom use of these agents is contraindicated and that have no other available treatment options.
The purpose of this study is to evaluate antiviral activity and efficacy of entecavir (ETV) compared to adefovir in adults with chronic hepatitis B who have not been treated yet with an antiviral medicine.
The purpose of this study is to investigate the efficacy and safety of adefovir dipivoxil for the treatment of chronic hepatitis B in children and adolescents (age 2 to less than 18 years) following 48 weeks of placebo-controlled, double-blind treatment and following an additional 192 weeks of open-label adefovir dipivoxil treatment.
This research study was conducted to compare the safety and effectiveness of the investigational medication, LdT (Telbivudine) versus Lamivudine, a drug currently approved by the US, European and Asian Health Authorities for the treatment of Hepatitis B infection. The results for patients taking LdT will be compared to results for patients taking lamivudine.
This is a multi-center phase 3, open-label, parallel-group study designed to evaluate the efficacy, safety and pharmacokinetics of adefovir dipivoxil liquid suspension in patients with chronic hepatitis B and varying degrees of renal impairment.
This study is being conducted to compare the safety and effectiveness of the investigational medication, LdT (Telbivudine) with Lamivudine, a drug currently approved by the US, European and Asian Health Authorities for the treatment of hepatitis B infection. The results for patients taking LdT will be compared to results for patients taking Lamivudine.
