Active clinical trials for "Hepatitis C, Chronic"

This study will evaluate the efficacy, safety, and tolerability of sofosbuvir (SOF; GS-7977) in combination with ribavirin (RBV) with or without pegylated interferon (Peg-IFN) in adults with chronic hepatitis C virus (HCV) infection who participated in a prior Gilead HCV study and have not achieved sustained virologic response (SVR).

The aim of the study is to confirm efficacy and safety of treatment with 600 mg of BID BI 207127 in combination with 120 mg QD FDV and RBV for 16 or 24 weeks in target chronically infected HCV GT1b treatment naïve patients, including patients with compensated cirrhosis.

The purpose of this study is to investigate if nitazoxanide used in combination with interferon alfa and ribavirin is effective in treating Hepatitis c infected type 2 Diabetic patients by improving their sustained viral response by more than 80%.Considering that the study is being conducted in a third world country like Pakistan, the standard treatment of hepatitis C is not cost effective. The aim is to introduce a new treatment comparable in efficacy to peginterferon and also cost effective.

The purpose of this study is to evaluate the safety and antiviral activity of ABT-450/ritonavir/ABT-267 (ABT-450/r/ABT-267; ABT-450 also known as paritaprevir; ABT-267 also known as ombitasvir) and ABT-333 (also known as dasabuvir) with and without ribavirin (RBV) in patients with chronic hepatitis C virus genotype 1b (HCV GT1b) infection without cirrhosis.

The primary objective of the study is to evaluate the safety and tolerability of voxilaprevir (formerly GS-9857) alone or with sofosbuvir (SOF)/velpatasvir (VEL) fixed dose combination (FDC) and antiviral activity of voxilaprevir in adults with genotype 1, 2, 3, 4 hepatitis C virus (HCV) infection. All participants will be monitored for up to 48 weeks after the last dose.

Parts A and B of this study are designed to evaluate the safety, tolerability, efficacy and pharmacokinetic profiles of samatasvir and simeprevir when administered in combination with ribavirin (RBV) for 12 weeks in treatment-naïve, Genotype (GT) 1b, 4 and 6 hepatitic C virus (HCV)-infected participants. Part C of this study is designed to evaluate the safety, tolerability, efficacy and pharmacokinetic profiles of samatasvir, simeprevir, TMC647055 and ritonavir (RTV) when administered in combination with or without RBV for 12 weeks in treatment-naïve or interferon/RBV-treatment relapsed, GT 1a and 1b HCV-infected participants.

A Phase 2 Study to Evaluate the Safety, Efficacy, Pharmacokinetics, and Pharmacodynamics of VX-135 and Daclatasvir in Treatment-Naïve Adult Subjects With Genotype 1 Chronic Hepatitis C

Multicenter prospective follow-up of a not controlled chronic hepatitis C genotypes 2/3 patients cohort with treatment indication with interferon α 2b and ribavirin for 24 weeks, and the verification of sustained virological response at week 48. The eligibility criteria and outcome measures followed the Clinical Protocol and Therapeutic Guidelines for Chronic Viral Hepatitis C, published by the Ministry of Health: http://portal.saude.gov.br/portal/arquivos/pdf/pcdt_hepatite_c_2011_retificado.pdf

This is a Phase 1 Open-Label, Parallel-Group, Single-Dose Study to evaluate the Pharmacokinetics of GS-5816 in subjects with normal hepatic function and moderate or severe hepatic impairment.

Hypothesis: the Telaprevir(TVR) plasma levels (750 mg q8h or 1125 mg/12h )will not be affected when co-administered with un-boosted Atazanavir (ATV) 200 mg q12h plus two analogues (NRTIs) in HCV/HIV-co-infected patients.
