Filter by:A significant proportion of HIV infected people in the U.S. are also infected with hepatitis C virus (HCV). The purpose of this study is to determine the effects of anti-HIV therapy on treatment of HCV with pegylated interferon alfa-2a and ribavirin (PEG/RBV).
This is a Phase 2, multi-center, randomized, open-label study to evaluate the safety, tolerability, and efficacy of Albuferon in subjects with hepatitis C (HEP C) who failed to respond to previous interferon alfa therapy.
This study is designed to compare the safety, tolerability and antiviral effects of omega interferon administered alone to omega interferon administered with ribavirin in the treatment of subjects with chronic Hepatitis C virus (HCV) infection.
To conduct epidemiological, laboratory, and survey research on volunteer blood donors within the United States to ensure the safety and availability of the United States' blood supply.
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.
The purpose of this study is to determine the safety and effectiveness of viramidine to ribavirin in chronic hepatitis C patients who have never before received treatment.
This trial is designed to test whether or not the addition of merimepodib (MMPD) to the standard therapy of pegylated interferon and ribavirin will result in a positive treatment response for people who have not previously responded to this therapy. Approximately 315 subjects will be enrolled in this research study at approximately 55 clinical sites in the United States. There will be three study groups. Everyone in the study will receive Pegasys® (pegylated interferon) and Copegus® (ribavirin) at the normally prescribed doses. Two of the groups will also receive the study drug merimepodib (MMPD) twice a day, one group at each dose level being tested. The third group will take a placebo instead of MMPD, with the Pegasys® and Copegus®. After the first 24 weeks of treatment, blood tests will be done to see if subjects are responding to treatment. If they are responding, they will continue receiving study treatment in the study for another 24 weeks. If they are not responding, they will stop study treatment. Everyone who is responding will be monitored for 24 weeks after the last dose of medication, to see how long the response lasts. Evaluations will be performed during the study to look at the safety of the Pegasys®/Copegus® and MMPD or placebo combination, and to see how the combination is working by measuring Hepatitis C Virus in the blood. At some of the clinical sites performing the study, some subjects may also participate in additional testing to look at the metabolism of the drugs, or to look at the immune response to Hepatitis C virus infection and treatment.
The purpose of this study is to determine if IDN-6556, when given orally, is safe and effective in patients with chronic hepatitis C virus infection.
This 4 arm study is designed for patients with CHC who have not responded to peginterferon alfa-2b (12KD)/ribavirin combination therapy. In these patients, the effects of lengthening the duration of treatment, as well as including an initial 12-week period of high-dose PEGASYS (360 micrograms sc), are compared with the standard combination therapy of PEGASYS (180 micrograms sc) and ribavirin (1000-1200mg po). The anticipated time on study treatment is 1-2 years and the target sample size is 500+ individuals.
