Filter by:This 6-arm study will assess the efficacy and safety of RO5024048 (R7128) in combination with the approved doses of Pegasys (180micrograms sc weekly) + Copegus (1000/1200mg po daily) (SOC), versus SOC in treatment-naive patients with chronic hepatitis C, genotype 1 and 4. The first 3 groups will receive 1) RO5024048 500mg bid + Pegasys + Copegus for 12 weeks, followed by SOC for 12 weeks; 2)RO5024048 1000mg bid + Pegasys + Copegus for 8 weeks, followed by SOC for 16 weeks; 3) RO5024048 1000mg bid + Pegasys + Copegus for 12 weeks, followed by SOC for 12 weeks. After 24 weeks, patients in these 3 groups who have achieved rapid viral response will stop treatment, and those who have not will receive SOC for a further 24 weeks. Group 4 will receive RO5024048 1000mg bid + Pegasys + Copegus for 12 weeks, followed by SOC for 36 weeks, and group 5 will receive SOC for 48 weeks. Group 6 provides retreatment on an open-label basis for patients of Group 5 who failed treatment. Patients will receive RO5024048 1000mg bid + Pegasys + Copegus for 24 weeks, followed by SOC for 24 weeks. The anticipated time on study treatment is 6-12 months.
The purpose of this study is to determine whether TMC435 influences the activity of certain drug-degrading proteins in the human body. The drug-degrading proteins investigated in this study belong to the Cytochrome P (CYP) family and are called CYP1A2, CYP2C9, CYP2D6, CYP3A4 and CYP2C19. The activity of these drug-degrading enzymes are determined by measuring the blood levels of a selected set of drugs, which are taken together with TMC435, and, which are known to be specifically degraded by a certain member of the CYP family. This selected set of drugs (which are taken together and therefore called a "drug cocktail") are considered as "probes" of these respective drug-degrading enzymes. By measuring the levels of these probes in human blood, the activity of these degrading enzymes are being revealed. In this way, we can determine if TMC435 influences in one way or another the activity of one or several of these selected drug-degrading proteins.
The primary objective of this study is to evaluate the impact of chronic hepatitis C (CHC), and the treatment thereof with peginterferon alpha-2b (PEG) and ribavirin (RBV) according to standard clinical practice, on the health-related quality of life (HRQL) of a cohort of participants throughout 72 weeks of follow-up. HRQL was assessed using the 36-Item Short-Form Health Survey (SF-36) and the Chronic Liver Disease Questionnaire-Hepatitis C Virus (CLDQ-HCV).
This study will test two different formulations. The results will be used to select formulation for phase 3.
A Study to assess the general safety and tolerability of the administration of a 3-dose prime/boost regimen of the MRKAd5 HIV-1 gag vaccine (V520) in subjects with chronic hepatitis C virus infection.
The purpose of this study is to compare several Debio 025 (alisporivir)/peg-IFNα2a/ribavirin triple therapies with the current standard of care (SOC) in treatment naïve chronic hepatitis C genotype 1 patients.
Current treatment of chronic liver disease relies upon removing the primary insult to the liver (e.g., alcohol) or treating the underlying viral infection (HBV, HCV, etc.). However, in the case of hepatitis C, a significant number of individuals will not clear the virus with current approved standard antiviral therapy, leaving them no options to manage their hepatic fibrosis, which can progress to cirrhosis and ultimately hepatocellular carcinoma (HCC). Fuzheng Huayu has been used in numerous studies in China and has been found to have a satisfactory prophylaxis effect on the chronic liver injury and formed liver fibrosis in rats and humans. In addition, it enhances the degradation of liver fibrosis and protects hepatocytes from injury and death, manifesting as decreasing of ALT and AST, and enhancement of albumin level. In addition, preliminary studies indicate that the Fuzheng Huayu has a good safety and tolerability profile with promising efficacy. The number of patients failing Interferon based therapy (i.e. not achieving SVR) is increasing. There are no approved standard of care treatment options for this population nor for patients who are intolerant or unwilling to receive Interferon; thus they are at higher risk for the progression of fibrosis. Moreover, there are no approved therapies to treat hepatic fibrosis, but basic research is exploring the pathophysiological mechanisms. Fuzheng Huayu is easy to administer, with a good safety and efficacy profile against fibrosis. Therefore, the investigators propose to further study the safety and efficacy profile of Fuzheng Huayu in a randomized, placebo-controlled, double blind study in Chronic Hepatitis C patients with hepatic fibrosis who have failed prior anti-HCV therapy or are intolerant or refuse Interferon based therapy. The primary objective of this study is to establish the safety and efficacy of Fuzheng Huayu treatment in chronic hepatitis C subjects who have failed prior anti-HCV therapy or cannot receive or refused Interferon based therapy in improving liver fibrosis.
The purpose of this study was to assess the safety, tolerability, pharmacokinetics and antiviral activity of ABT-333 (also known as dasabuvir) in treatment-naïve, hepatitis C virus (HCV)-infected participants.
This study is designed to test the hypothesis that treatment of hepatitis C virus (HCV) infection during the first 6 months after acquiring HCV among people who already have pre-existing HIV infection will result in improved responses to HCV therapy with a shorter duration of infection.
Based on previous experience with peginterferon alfa-2b/ribavirin in combination with boceprevir, the combination with peginterferon alfa- 2a/ribavirin and boceprevir is expected to be safe and well tolerated. Given the wide utilization of both peginterferons and the clear benefit of the addition of boceprevir to peginterferon alfa-2b/ribavirin, it is important to demonstrate the safety and efficacy of boceprevir in combination with peginterferon alfa-2a/ribavirin.
