Active clinical trials for "Hepatitis C"

This Phase II, open-label, parallel-arm study will evaluate the safety, tolerability, pharmacokinetics and antiviral activity of ritonavir-boosted danoprevir in combination with Pegasys (peginterferon alfa-2a) and Copegus (ribavirin) in treatment-naïve patients of Asian origin with chronic hepatitis C genotype 1. Patients will receive danoprevir 125 mg plus ritonavir 100 mg as fixed dose tablet orally twice daily in combination with weekly Pegasys 180 mcg subcutaneously and Copegus 1000-1200 mg orally daily in divided doses. Treatment duration is 12 weeks in patients without cirrhosis and 24 weeks in patients with compensated cirrhosis.

Egypt has the highest prevalence of hepatitis C virus infection in adults (up to 20%) and children (up to 5.5%). The major genotype (90%) is type 4. Pegylated interferon-alpha-2a or -2b and ribavirin have been used in small numbers of hepatitis C virus-infected children with sustained virological response being higher in genotypes 2 and 3 than in genotypes 1 and 4. Genotype 4 is has been described as difficult-to-treat genotype. Several attempts to modify treatment protocols have been tried in adults in an attempt to achieve higher rates of sustained virological response. Shortening injection interval and/or treatment duration prolongation have been tried with variable outcome reports. A novel Hansenula- derived pegylated interferon alpha 2a: 20 Kilo dalton (Reiferon Retard) has been used over the last 4 years in the Egyptian market. We aimed to investigate the safety and efficacy of Reiferon retard plus ribavirin customized regimen in hepatitis C virus-RNA seropositive Egyptian children. Forty six children with chronic hepatitis C virus aged 3-19 years were selected from 3 hepatic tertiary centers. Clinical and laboratory evaluation were undertaken. Quantitative polymerase chain reaction (PCR) for HCV-RNA was done before starting treatment, at 4, 12, 24, 48, 72 weeks during treatment and 6 months after stoppage of treatment. All patients were assigned to receive a weekly subcutaneous injection of pegylated interferon alpha 2-a ( Reiferon Retard) plus oral Ribavirin daily for 12 weeks ,then cases were divided according to PCR results into 2 groups. Group I: Patients who continued treatment on weekly basis: this group included patients who had negative PCR at week 12 as well those who had positive PCR without any change in viremia. Group II: Patients who continued treatment on a 5- days schedule: this group included patients who had any decrease in viremia at week 12. Patients who were PCR-negative at week 48 and had at least one PCR-positive test during therapy were assigned to have an extended treatment course of 6 months duration. The occurrence of adverse effects was assessed during treatment and follow up

The primary objectives of this study are to evaluate the efficacy, safety, and tolerability of treatment with ledipasvir/sofosbuvir (LDV/SOF) fixed-dose combination (FDC) in treatment-naive and treatment-experienced participants with chronic genotype 1 hepatitis C virus (HCV) infection.

This a phase 2, randomized, open-label trial of GS-9256 plus GS-9190, two oral anti HCV drugs, for 28 days with and without ribavirin (RIBA) and with pegylated interferon (PEG)/RIBA in adults with chronic Hepatitis C virus (HCV). In Part A, approximately thirty (30) subjects 18-70 years of age who meet study entry criteria will be randomized (in other words, selected at random, like flipping a coin) to one of the two treatment groups (GS-9256 plus GS-9190 or GS-9256 plus GS-9190 plus RIBA). In Part B, an additional fifteen (15) subjects will receive 75 mg GS-9256 BID plus 40 mg GS-9190 BID in combination with PEG/RIBA. After the 28-day treatment period, subjects will receive PEG/RIBA as standard of care (SOC). Following randomization, subjects will return for a Baseline (Day 1) visit, at which time study medication will be dispensed and subjects will enter a 28 day treatment phase. During the treatment phase, subjects will receive oral study drugs twice daily for 28 days and PEG once weekly for Part B. Subjects then receive PEG/RIBA as local SOC starting on Day 28 (not provided as part of the study). Following completion of the 28-day treatment phase, subjects will be followed for approximately 72 weeks.

The purpose of this study is to determine whether a human monoclonal antibody against Hepatitis C (MBL-HCV1) is effective in preventing detectable levels of Hepatitis C virus in patients undergoing liver transplantation due to chronic HCV infection. The study will also determine if MBL-HCV1 is effective in delaying or reducing the amount of detectable HCV in patients after transplant.

The purpose of this study is to assess the safety, tolerability and effectiveness of ANA598 when administered with pegylated interferon and ribavirin (Standard of Care [SOC]) compared to placebo + SOC.

The purpose of this study is to evaluate the effect of telaprevir on the results of electrocardiograms in healthy volunteers. An electrocardiogram is an electric recording of the heart. Telaprevir is being investigated for the treatment of chronic hepatitis C virus infection.

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.

The purpose of this research study is to find out the effect of the investigational drug NOV-205 on the level of hepatitis C virus in the blood and whether NOV-205 is well-tolerated at different doses when taken by subjects with hepatitis C.

To determine safety, tolerability, and preliminary efficacy of escalating doses of SD-101 alone and SD-101 plus ribavirin in subjects with chronic hepatitis C and no prior therapy.
