Filter by:Study SPC3649-207E is designed as an extension study to the prior protocol to provide additional long-term safety and efficacy information for subjects participating in Study SPC3649-207.
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
To evaluate the safety, tolerability and immunogenicity of VGX-6150 as second-line therapy in chronic hepatitis C patients
This is a Phase 3, randomized, open-label, multicenter study, enrolling non-cirrhotic and cirrhotic subjects. The purpose of this study is to evaluate the efficacy and safety of ABT-450/r/ABT-267 co-administered with weight-based RBV for 12 or 16 weeks in adult chronic HCV genotype 2-infected treatment-naïve and interferon (IFN) treatment-experienced subjects with and without compensated cirrhosis.
This is a phase 3, double-blinded, multicenter study. The study will consist of 2 substudies: Substudy 1 (SS1) will be double-blinded and enroll non-cirrhotic subjects and Substudy 2 (SS2) will be open label and enroll subjects with compensated cirrhosis.
GSK2878175 is a site IV NS5B non-nucleoside inhibitor (NNI) being developed for the treatment of chronic hepatitis C virus (HCV) infection. The purpose of this study is to investigate the effects of GSK2878175, at different doses in men and women infected with chronic hepatitis C virus. The study will investigate how much of the drug gets into the blood stream and how long the body takes to get rid of it. The study will also investigate if GSK2878175 has any important side effects. The study will also measure what effect GSK2878175 has on the hepatitis C virus infection after taking the study medication for 2 days. Approximately 44 people will take part in this study. Depending on the type of chronic hepatitis C infection a subject will be enrolled into 1 of 4 groups randomly. Each group will participate in one dosing session. One dosing session consists of GSK2878175 or a placebo (sugar pill) given once per day for 2 days. Group A, B, and C is made up of 8 participants per group. In each of these groups 6 participants will receive GSK2878175 and 2 participants will receive placebo. Group D is made up of 20 participants. 15 participants will receive GSK2878175 and 5 participants will receive placebo. The treatment groups will be dosed in sequence. Group A will be the first to take the study medication, then Group B, and so on. The plan is to dose subjects in Group A with 10 mg, Group B with 30 mg, Group C with 60 mg, and Group D with 60 mg of GSK2878175 or placebo. The next treatment group's actual dose will be decided after looking at the results from the previous group. The doses may therefore be higher or lower than planned depending on the previous group's results. The number of participants enrolled in the next group may also change depending on the results from the previous group.
The purpose of this study is to determine the progression of chronic hepatitis C patients infected by paid plasma donation,and explore the possible pathogenic mechanisms of disease progression in chronic hepatitis C.
This study will explore ways to improve the effectiveness of patient Self Management at a time when genetic test results guide new treatments that will dramatically increase the possibility of cure of the hepatitis C virus.The study will also focus on the interactions between provider and patients and the ways that technical work, adaptive work and adaptive leadership foster patient self-management.This proposed 2 year exploratory mixed-methods 12 longitudinal case study will explore patients' and providers' explanations for how and why they engage in technical work, adaptive work, and adaptive leadership and the ways in which these strategies promote or pose barriers to patients' self-management of Chronic Hepatitis C in the context of the new genetic test results and treatments. Specific aims are to: 1: Examine how technical work, adaptive work and adaptive leadership influence patients' perceptions of their likelihood of cure and how this work relates to self-management during 12 to 24 weeks of treatment for Chronic Hepatitis C. Research questions are: 1.1) How do patients describe their interactions with the providers? 1.2) How do these interactions shape patients' perceptions of the likelihood of cure? 1.3) How do patients' understanding of their interactions with the provider promote the use of or pose barriers to self-management during treatment? AIM 2: Describe providers' use of technical work, and adaptive leadership approaches during clinical encounters,to include nurse education visits. Research questions are: 2.1) What technical work, and adaptive leadership approaches do providers use when sharing treatment information with patients during the clinical encounters. 2.2) What explanations do providers give for how and why they use technical work and adaptive leadership approaches? AIM 3: Describe the trajectories of illness perceptions(Control/Cure sub-scale - Illness Perception Scale), symptoms (M.D. Anderson Symptom Inventory) , viral load, and self-management (Patient Activation Measure) in relation to patient and provider reports of technical work, adaptive work, and adaptive leadership from the index clinical encounter to the follow-up treatment response encounter (ranging from 12 to 24 weeks).
Treatment of hepatitis C virus (HCV) infection was carried out using pegylated interferon (PEG-IFN), ribavirin (RBV) and vitamin D (vit D) for 48 weeks in HCV genotypes 4a subjects. The purpose of this study is to determine the effect of vitamin D on liver affection in such patients.
The purpose of this study is to evaluate the safety and antiviral effect of multiple doses of ABT-493 and ABT-530 in adults with genotype 1 HCV.
