Filter by:The purpose of this study is to examine the effects of valacyclovir in patients who have chronic hepatitis C, antibodies to herpes simplex type 1 infection but do not have antibodies to herpes simplex type 2 infection. Herpes simplex type 1 infection commonly causes cold sores or fever blisters, also known as herpes labialis, but most persons do not have any symptoms at all. Valacyclovir is a medication which is approved by the Food and Drug administration to treat herpes labialis. Valacyclovir has not been approved to treat chronic hepatitis C infection. The study will take 16 weeks. Participants will be assigned to take either the study drug, valacyclovir, or a sugar pill that looks exactly like valacyclovir. The researchers and patients will not know which medication they are receiving. Study visits will occur every two weeks and will take approximately 30-45 minutes. All study visits will occur at the G.V. Sonny Montgomery VA Medical Center in Jackson, Mississippi.
The purpose of this study is to assess the safety, tolerability, pharmacokinetics, and antiviral activity of multiple, ascending doses of ABT-267 (also known as ombitasvir) administered as two-day monotherapy followed by ABT-267 in combination therapy with other direct-acting antiviral agents (DAAs) ABT-450 with ritonavir (ABT-450/r) and ABT-333 (also known as dasabuvir) plus ribavirin (RBV) in patients with chronic Hepatitis C virus (HCV) infection without cirrhosis.
The purpose of this study is to study the effects of valacyclovir on patients who have hepatitis C and antibodies to herpes simplex type-2. Herpes simplex type 2 is a virus which causes genital herpes. Some persons with genital herpes have sores in their private areas but most persons do not have any symptoms at all. Valacyclovir is a medication which is commonly used to treat or prevent outbreaks of genital herpes. This medication is already approved by the Food and Drug Administration to treat genital herpes. Valacyclovir has not been approved to treat chronic hepatitis C. The study will take 16 weeks. Participants will be assigned to take either the study drug, valacyclovir, or a sugar pill that looks exactly like valacyclovir. The researchers and the persons participating will not know which medication they are receiving. Study visits will occur every two weeks and will take approximately 3-45 minutes. All study visits will occur at the G.V. Sonny Montgomery VA Medical Center.
The purpose of this study is to evaluate the antiviral activity, safety, and pharmacokinetics of ABT-450 with ritonavir (ABT-450/r) dosed in combination with ABT-333 (also known as dasabuvir) and ribavirin (RBV) in treatment-naïve and non responder participants with genotype 1 chronic hepatitis C virus (HCV) infection.
This study is to assess the safety and tolerability of sofosbuvir (SOF) 400 mg with and without ribavirin (RBV) and/or with and without pegylated interferon alfa-2a (PEG) in subjects with genotype 1, 2 or 3 hepatitis C (HCV) infection.
This phase 2b study will evaluate the efficacy and safety of 16 and 24 weeks of response-guided duration of therapy with GS-9190 and GS-9256 in combination with Peginterferon Alfa-2a (Pegasys®) and Ribavirin (Copegus®). Additionally, the efficacy and safety of 24 weeks of GS-9256 in combination with Peginterferon Alfa-2a (Pegasys®) and Ribavirin (Copegus®) will be evaluated.
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and antiviral activity of ABT-450 with ritonavir (ABT-450/r) dosed in combination with ABT-072 and ribavirin (RBV) in treatment-naïve participants with genotype 1 chronic hepatitis C virus (HCV) infection.
The primary objective of this study is to evaluate the safety and tolerability of ascending doses of Hanferon™ in combination with ribavirin (RBV). The secondary objective of this study is to define the PK and PD of ascending doses of Hanferon™ in combination with RBV. The exploratory objective of this study is to make a preliminary assessment of Hanferon™ efficacy in combination with RBV.
This study assessed the safety, tolerability, pharmacokinetics, and antiviral activity of multiple oral doses of ABT-450/ritonavir (r), ABT-333 (also known as dasabuvir), or ABT-072 in hepatitis C virus (HCV), genotype 1-infected, treatment-naïve adults.
The primary objective of this protocol is to study the effect of the standard of care in hepatitis C (pegylated interferon and ribavirin) associated with therapeutic vaccine TG4040 on the viral load of treatment-naïve patients with chronic genotype 1 hepatitis C infection.
