Filter by:This is a study of combination direct-acting antiviral agents (DAA) with or without ribavirin (RBV) in patients with chronic Hepatitis C Virus (HCV).
The efficacy of combination antiviral therapy for chronic hepatitis C is influenced by many factors. Important patient-specific factors include, age, gender, race, body weight. Important virus-specific factors include HCV genotype and serum HCV RNA level. Finally, important treatment-related factors include the type of interferon, dose of ribavirin and the duration and adherence to treatment. Despite the importance of patient- and virus-specific factors, the most important indicator of treatment success is a rapid, profound and sustained decrease in serum HCV RNA levels after the start of treatment. The on-treatment virological response can thus be used to predict the probability that a given patient will achieve an SVR if they remain on therapy. It can also be used to individualize the duration of treatment. In this study, treatment for patients with chronic hepatitis C was individualized on the basis of clinical characteristics and the on-treatment virological response. The aim was to investigate the usefulness of undetectable HCV RNA levels at week 4 (RVR) and 12 in tailoring the duration of treatment and predicting SVR in Chinese patients with chronic hepatitis C.
A Study to Evaluate the Efficacy, Safety and Pharmacokinetics of ABT-450 with Ritonavir (ABT-450/r) when given together with ABT-267 and with and without Ribavirin (RBV) in Treatment-Naïve Subjects with Genotype 1, 2 or 3 Chronic Hepatitis C Virus (HCV) Infection.
The purpose of this study is to estimate the rate of sustained virologic response (SVR) SVR12, where SVR12 is defined as HCV RNA < LOQ (detectable or undetectable) 12 weeks post-treatment in Genotype 1 & Genotype 4 treatment naive patients, and Genotype (GT1) infected patients who are prior null responders to pegIFN/ribavirin
The aim of this study is to investigate the relationships between drug response and the host genetic factors, viral factors and clinical factors in chronic hepatitis C patients (HCV). And thus, the investigators are trying to develop the pharmacogenomic guideline in the Korean patients with HCV.
The purpose of this study is to study the effects of valacyclovir on patients who have hepatitis C and antibodies to herpes simplex type-2. Herpes simplex type 2 is a virus which causes genital herpes. Some persons with genital herpes have sores in their private areas but most persons do not have any symptoms at all. Valacyclovir is a medication which is commonly used to treat or prevent outbreaks of genital herpes. This medication is already approved by the Food and Drug Administration to treat genital herpes. Valacyclovir has not been approved to treat chronic hepatitis C. The study will take 16 weeks. Participants will be assigned to take either the study drug, valacyclovir, or a sugar pill that looks exactly like valacyclovir. The researchers and the persons participating will not know which medication they are receiving. Study visits will occur every two weeks and will take approximately 3-45 minutes. All study visits will occur at the G.V. Sonny Montgomery VA Medical Center.
This prospective, multicenter, observational cohort study will evaluate the efficacy and safety of peginterferon alfa (e.g. Pegasys) plus ribavirin and treatment regimens containing direct-acting antivirals in patients with chronic hepatitis C who are treatment-naïve or treatment-experienced and HIV HCV co-infected. Data will be collected from patients receiving treatment according to current Summary of Product Characteristics and local labeling for the duration of their treatment and a 24-week follow-up.
Standard therapy for chronic hepatitis C virus (HCV) is (Peg/RBV) combination therapy obtaining sustained virologic response (SVR) in 77% of naïve patients with genotype 1-3 Studies rarely address the issues of improving host factors. The current study examines whether adding vitamin D with Peg/RBV, a potent immunomodulator, could improve viral response(SVR)compared to Peg/RBV.
GSK2336805 is a hepatitis C virus (HCV) NS5A inhibitor being developed for the treatment of chronic hepatitis C (CHC). This study will assess the safety, antiviral activity, and pharmacokinetics of GSK2336805 alone and in combination with peginterferon alfa 2a and ribavirin in subjects with chronic hepatitis C (CHC).
The purpose of this study is to provide entecavir to participants who have completed another entecavir trial without achieving virologic response or who relapsed during postdosing follow-up.
