Active clinical trials for "Hepatitis C, Chronic"

This 2 arm open-label study will assess the safety and tolerability of combination treatment with Peginterferon alfa (Pegasys) and Ribavirin (Copegus) in patients with chronic hepatitis C. Patients will be assigned to receive Peginterferon alfa (Pegasys) 180 mcg sc once a week and Ribavirin (Copegus) 800 - 1200 mg po daily for either 24 or 48 weeks. Allocation to the treatment arms is to the discretion of the investigator (mainly according to genotype). Adverse events will be monitored throughout the study and hematologic parameters every 2 weeks and twice during the 24-week follow-up.

The purpose of this study is to investigate the safety, tolerability, and antiviral activity of ANA598 in patients with genotype-1 chronic hepatitis C infection.

The objective of the study is to select an optimal dose of taribavirin by comparing the efficacy and safety of 3 taribavirin dose levels, 20, 25, and 30 mg/kg/day, versus ribavirin 800 to 1400 mg/day based on body weight, both administered in combination with peginterferon alfa-2b to therapy-naive patients with chronic Hepatitis C Virus (HCV) genotype 1 infection.

The purpose of this study is to determine if CTS-1027 can lower elevated liver enzymes in patients with chronic HCV infection.

This study will compare the efficacy and safety of treatment with pegylated-interferon alfa-2a plus ribavirin in participants with non-genotype 2/3 CHC who, after 12 weeks of study treatment, have undetectable hepatitis C virus (HCV)-ribonucleic acid (RNA) or a greater than or equal to (>=) 2 log10 drop in HCV-RNA. Participants will be randomized to receive pegylated-interferon alfa-2a 180 micrograms subcutaneously weekly plus ribavirin (1000-1400 milligram [mg]) orally daily for the specified duration, followed by 24 weeks of treatment-free follow-up. Participants with detectable HCV-RNA and less than (<) 2 log10 drop in HCV-RNA at week 12 will discontinue therapy.

Chronic hepatitis C virus (HCV) infection is prevalent in the world, affecting 3% of the world's population. The current standard of therapy is pegylated interferon and ribavirin, reaching 54-63% of successful rates. In patients with HCV genotype 1 infection, a 48 week course of combination therapy has achieved a higher successful rate that a 24 weeks course of therapy. However, several studies in Taiwan have shown that a 24 week course of therapy has comparable or even better response to a 48 week course of therapy in Western countries. Therefore, whether a 48 week course of therapy can achieve a higher response to a 24 week course of therapy in Taiwanese patients with genotype 1 HCV infection remains unclear.

This study will examine the effectiveness of S-adenosyl methionine (SAMe) in combination with peginterferon and ribavirin for treating hepatitis C virus. One out of three patients with hepatitis C develops cirrhosis of the liver, which can lead to liver failure or liver cancer. SAMe is a nutritional supplement that is made naturally in all cells of the body and acts to improve how the body handles stress. In laboratory experiments with liver cells, SAMe decreases the injury caused by liver toxins and improves the ability of interferon to block hepatitis C virus. Patients 18 years of age and older with hepatitis C infection who did not respond successfully to prior treatment with interferon and ribavirin or peginterferon and ribavirin may be eligible for this study. Participants receive the following treatment: Peginterferon (given by injection) and ribavirin (taken by mouth) for 2 weeks Washout period (no medications) for 4 weeks SAMe (taken by mouth) for 2 weeks Peginterferon, ribavirin and SAMe for 12-48 weeks, depending on patient response to treatment. Participants have a thorough physical evaluation before beginning treatment and again at the study's end. After starting treatment, patients return for clinic visits and blood tests weekly for the first several weeks, then less frequently (at 2-week, then 4-week and 8-week intervals until up to 72 weeks) to monitor symptoms, drug side effects, hepatitis C virus levels, liver enzyme levels and immune responses to hepatitis C. ...

This 4 arm study will compare the safety and tolerability of HCV polymerase inhibitor pro-drug in combination with PEGASYS +/- COPEGUS with the standard of care therapy of PEGASYS + COPEGUS, in treatment-naive patients with CHC, genotype 1. Patients will be randomized to receive 1500mg or 3000mg po bid of HCV polymerase inhibitor pro-drug + PEGASYS, 1500mg of HCV polymerase inhibitor pro-drug + PEGASYS + COPEGUS or PEGASYS + COPEGUS for 4 weeks. All patients who receive at least one dose of study medication will receive open label PEGASYS + Copegus for an additional 44 weeks after the 4 week experimental period. The anticipated time on study treatment is 3-12 months, and the target sample size is <100 individuals.

The purpose of this study is to determine the safety and tolerability of bavituximab when administered via an arm vein as multiple infusions and to examine how bavituximab behaves in the body and how it effects the amount of hepatitis C virus and immune modulators in individuals with chronic infection.

This 7 arm study will determine the optimal treatment combination, based on efficacy and safety. Patients with chronic hepatitis C (CHC), genotype 1, will be randomized to one of 7 treatment groups. Groups 1, 2, 4, 5 and 6 will receive triple combination treatment with HCV polymerase inhibitor pro-drug (at doses of 500, 1000 or 1500mg po bid) plus PEGASYS (90 or 180 micrograms sc weekly) plus Copegus (1000 or 1200mg po qd) for 24 weeks, followed by 24 weeks of open label Standard of Care (PEGASYS 180 micrograms sc weekly plus Copegus 1000/1200mg po qd). Group 3 will receive HCV polymerase inhibitor pro-drug 500mg po bid plus PEGASYS 180 micrograms sc weekly plus Copegus 1000/1200mg po qd for 24 weeks; after 24 weeks, those achieving a rapid virological response (RVR) will stop all medication, and non-RVR patients will remain on triple combination for an additional 24 weeks. Group 7 will receive standard of care (SOC) for 48 weeks. There will be a 24 week period of treatment-free follow-up for all treatment groups. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.
