Filter by:To compare the sustained virological response (SVR = ribonucleic acid (RNA) - hepatitis C virus (HCV) undetectable at week 24 before end the treatment) in chronic hepatitis C patients genotype 1-4 co-infected with HIV-HCV, treated with Peginterferón alfa-2a (40 KD) 180 µg/week and Ribavirin (2000 mg/day during 4 weeks, follow of 1000-1200 mg/day, according to body weight); versus Peginterferón alfa-2a (40 KD) 180 μg/week and Ribavirin (1000-1200 mg/day, according to body weight). To evaluate the impact to extend the treatment with Peginterferon alfa-2a and Ribavirin to week 72, in SVR of these patients with genotypes 1-4 without rapid virological response (RVR = RNA - HCV undetectable at 4 week).
The purposes of this study are: - to determine the safety and tolerability of multiple doses of A-831 at various doses - to determine how multiple doses of A-831 are distributed through the bloodstream - to determine if A-831 reduces the amount of Hepatitis C virus in the blood
Omega DUROS® is an implantable drug delivery system designed to deliver omega interferon subcutaneously at a constant rate for 90 days. This study is being performed to evaluate the safety and antiviral effects of omega interferon delivered by the Omega DUROS® device in combination with ribavirin in subjects with chronic Hepatitis C genotype 1.
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.
The purpose of this study is to assess the ability of eltrombopag to maintain a platelet count sufficient to facilitate initiation of antiviral therapy, to minimise antiviral therapy dose reductions and to avoid permanent discontinuation of antiviral therapy. The clinical benefit of eltrombopag will be measured by the proportion of subjects who are able to achieve a Sustained Virological Response (SVR).
This trial is designed to assess the safety, tolerability, pharmacokinetics and viral kinetics after multiple infusions of bavituximab in patients co-infected with HCV and HIV.
Genotype 4 hepatitis C virus is the cause of approximately 20% of the 170 million cases of chronic hepatitis C in the world. Although rare in western nations, genotype 4 is the most common variant of the hepatitis C virus in Egypt and is also found throughout Africa and the Middle East. Early reports on the treatment of patients with genotype 4 chronic hepatitis C with interferon-alfa (IFN)-alfa monotherapy indicate poor rates of sustained viral response (SVR). With the introduction of ribavirin combination therapy and with pegylation of the IFN alfa molecule, however, response rates have improved dramatically, and current clinical trial data indicate that SVR rates between 43 and 79% are attainable in genotype 4 patients who are receiving pegylated IFN alfa plus ribavirin for 48 weeks. Clinical advances to optimize treatment for each patient have also been made, and tailored treatment options are now being developed that are comparable to the treatment approaches for genotype 1, 2, and 3 patients. A treatment duration of between 36 and 48 weeks appears to be optimal for most patients with chronic hepatitis C genotype 4.The aim of this study is to assess the efficacy and safety of pegylated interferon alpha 2a in patients with chronic hepatitis C genotype 4 in comparison to a historical cohort of patients treated with pegylated interferon alpha 2b
The purpose of the study is to evaluate whether Viusid, a nutritional supplement, reduce the mortality and the complications (ascites, spontaneous bacterial peritonitis, hepatorenal syndrome, hepatic encephalopathy, gastrointestinal bleeding, sepsis and hepatocellular carcinoma) of patients with cirrhosis of the liver secondary to HCV infection in comparison with placebo, during 96 weeks of treatment.
The purpose of this study is to determine if nitazoxanide in combination with peginterferon alfa-2a and ribavirin is safe and effective in treating chronic hepatitis C in patients that have previously failed to respond to treatment with peginterferon and ribavirin.
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.
