Active clinical trials for "Hepatitis C, Chronic"

The purpose of this study is to examine the safety and effectiveness of GI262570 compared to placebo (a pill that looks exactly like GI262570 but contains no active medicine) in improving specific tests that indicate the degree of liver fibrosis (scarring). Subjects who are enrolled in the study must have had prior treatment with interferon (either pegylated or standard interferon) plus ribavirin for at least 12 weeks to treat their hepatitis C, but either failed to clear the virus or didn't tolerate the treatment.

The presence of insulin resistance (IR) appears to be a key factor in the development of steatosis and disease progression in patience with Hepatitis C virus (HCV) genotype-1 infections similar to levels in Non-alcoholic fatty liver disease (NAFLD). The objective of this study is to determine whether Pioglatizone, when given along with Interferon and Ribavirin, reduces insulin resistance and lowers HCV viral levels and improved response in patients who have HCV genotype-1 infection when compared to a placebo.

Objectives: Primary To compare the sustained virologic response (SVR) of PEGIntron plus ribavirin among patients receiving 48 weeks versus 72 weeks of therapy (defined as undetectable HCV RNA level 24 weeks after discontinuing therapy). Secondary To evaluate the safety and tolerability PEG Intron in combination with ribavirin for treatment of Chronic Hepatitis C (CHC) infection in patients co-infected with Human Immunodeficiency Virus (HIV). To determine the early virologic response of patients receiving PEGIntron plus ribavirin at Treatment Week 24 Study Design: All qualifying patients will enter the treatment phase and be dosed as follows: Peginterferon a-2b 1.5mg/kg by subcutaneous route once weekly plus Ribavirin: 800 mg (400 mg bid) if body weight < 65 kg 1000 mg (400 mg a.m. and 600 mg p.m.) if body weight > 65 kg and < 85 kg 1200 mg (600 mg bid) if body weight > 85 kg and < 105 kg 1400 mg (600 mg a.m. and 800 mg p.m.) if body weight > 105 kg At Treatment Week 24, all participants with detectable HCV-RNA will be discontinued from treatment and followed for a Post Treatment period of 24 weeks. Participants with undetectable HCV-RNA values at Treatment Week 24 will be randomized to either: Group A: an additional 24 weeks of previously assigned Peginterferon a-2b + Ribavirin therapy, for a total of 48 weeks of treatment. Group B: an additional 48 weeks of previously assigned Peginterferon a-2b + Ribavirin therapy, for a total of 72 weeks of treatment. Study Population: 300 HIV infected adults with chronic hepatitis C infection who have not been treated previously with interferon therapy. Dosage and Administration: Peginterferon a-2b 1.5mg/kg by subcutaneous route once weekly plus Ribavirin: 800 mg (400 mg bid) if body weight < 65 kg 1000 mg (400 mg a.m. and 600 mg p.m.) if body weight > 65 kg and < 85 kg 1200 mg (600 mg bid) if body weight > 85 kg and < 105 kg 1400 mg (600 mg a.m. and 800 mg p.m.) if body weight > 105 kg Efficacy Evaluations: Laboratory analysis, liver biopsies, quality of life assessments, and changes in Peginterferona-2b and Ribavirin dosages will be obtained. Safety Evaluations: Assessment of laboratory evaluations vital signs incidence and severity of adverse experiences dose adjustments premature withdrawal for safety reasons progression of disease as measured by HCV viral load AIDS defining events

The primary objective of this study is to determine the safe and effective dose range of boceprevir (SCH 503034) in combination with PEG-Intron in adult subjects who have chronic hepatitis C without cirrhosis, and who have failed an adequate course of combination therapy with peginterferon-alfa plus ribavirin. A secondary objective is to explore whether ribavirin provides an additional benefit when combined with PEG-Intron plus boceprevir.

Purpose of this study is to evaluate the safety, tolerability, antiviral activity, and pharmacokinetic behavior of ISIS 14803 administered for up to 12 weeks by intravenous infusions in patients with chronic hepatitis C.

The objective of this study is to determine the effectiveness of PEG-Intron 1.5 ug/kg/wk plus REBETOL (ribavirin) 800-1400 mg/day in adults with chronic hepatitis C with moderate to severe liver fibrosis or cirrhosis who failed to respond to previous treatment with an alpha interferon in combination with ribavirin. Patients who do not respond to PEG-Intron plus REBETOL (ribavirin) will be enrolled in a long-term maintenance study to evaluate the effectiveness of PEG-Intron monotherapy versus no treatment for the prevention of disease progression (Protocols P02569 and P02570).

Chronic hepatitis C infection is one of the leading causes of chronic liver disease in the United States. Approximately one-third of patients with hepatitis C infection develop cirrhosis of the liver, which can lead to liver failure or liver cancer. The current treatment for hepatitis C infection in previously untreated patients is successful in only about half of patients. There is no established therapy for non-responders. This is a randomized, double-blinded, multicenter trial to determine the effectiveness of thymosin alpha 1 (thymalfasin) 1.6 mg twice weekly plus PEGinterferon alfa-2a 180 ug/wk compared to placebo plus PEGinterferon alfa-2a in adults with chronic hepatitis C with early cirrhosis or progression to cirrhosis who are non-responders to previous treatment with interferon or interferon plus ribavirin. The definition of non-response requires a positive HCV RNA test at the end of a course of at least 12 weeks of therapy. Patients will receive treatment for 12 months, and will be followed-up for a further 6 months after the end of therapy

For those chronic hepatitis C patients, who are interferon-ineligible or intolerant, there is a burning need for the development of pan-oral interferon-free regimen. The investigators examine the efficacy and safety of sofosbuvir, a NS5B nucleotide polymerase inhibitor and daclatasvir, an NS5A replication complex inhibitor in Chinese treatment-experienced cirrhosis patients with chronic G1b infection.

The purpose of this study is to determine whether a regimen consisting of daclatasvir and asunaprevir is effective in treatment-naive patients with chronic hepatitis genotype 1b infection.

To evaluate the effect of ribavirin on second phase plasma hepatitis C virus (HCV) ribonucleic acid (RNA) decline in participants who receive ombitasvir/ABT-450/ritonavir and dasabuvir with full dose ribavirin, low dose ribavirin or without ribavirin for 2 weeks in treatment-naive HCV genotype (GT) 1a-infected adults.
