NCT ID: NCT01070550 Completed - Clinical trials for Hepatitis C, Chronic

PROPHESYS 1: An Observational Study on Predictors of Response in Treatment-naïve Patients With Chronic Hepatitis C Treated With Pegasys (Peginterferon Alfa-2a)

Start date: June 2007
Phase: N/A
Study type: Observational

This observational study will assess predictors of early on-treatment and sustained virological response in treatment-naïve patients with chronic hepatitis C initiated on treatment with Pegasys (peginterferon alfa-2a) and ribavirin. Data will be collected during the treatment period (24 or 48 weeks) and 12 and 24 weeks after the end of treatment. Target sample size is <5000.

NCT ID: NCT01070407 Completed - Hepatitis C Clinical Trials

A Study of a New Candidate Vaccine Against Hepatitis C Virus (HCV)

Start date: July 2007
Phase: Phase 1
Study type: Interventional

HCV001 is a Phase I study to ascertain the safety and immunogenicity of a novel vaccine against Hepatitis C virus (HCV). The vaccine is based on the sequential delivery, by intramuscular route, of two different adenoviral vectors, of human and chimpanzee origin respectively, bearing the same genetic information for HCV antigens (NS region). The two recombinant vectors, called Ad6NSmut and AdCh3NSmut, are weakened and unable to multiply within the body; they are designed to induce an immune response against HCV proteins. Although Ad6NSmut and AdCh3NSmut have never been given to humans before this trial, promising results have been obtained in non-human studies. The HCV001 study is designed to explore different prime-boost regimes concerning dose, order and interval of administration of Ad6NSmut and AdCh3NSmut.

Start date: October 2007
Phase: N/A
Study type: Observational

This observational study will assess predictors of early on-treatment and sustained virological response in treatment-naïve patients with chronic hepatitis C initiated on treatment with Pegasys (peginterferon alfa-2a) or peginterferon alfa-2b and ribavirin. Data will be collected during the treatment period (24 or 48 weeks) and 12 and 24 weeks after the end of treatment. Target sample size is <2000.

NCT ID: NCT01063023 Completed - Hepatitis C Virus Clinical Trials

Drug Interaction Oral Contraceptive Pill (OCP)

Start date: January 2010
Phase: Phase 1
Study type: Interventional

To assess the effects of BMS-650032 on Pharmacokinetics (PK) of ethinyl estradiol (EE) and norelgestromin (NGMN) in healthy female subjects

NCT ID: NCT01058512 Completed - Hepatitis C Clinical Trials

A Trial of NOV-205 in Hepatitis C Patients Who Failed Standard Therapy

NOV-205
Start date: March 2010
Phase: Phase 2
Study type: Interventional

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.

NCT ID: NCT01057667 Completed - Clinical trials for Hepatitis C, Chronic

A Study of RO5024048 in Combination With Pegasys (Peginterferon Alfa-2a) and Copegus (Ribavirin) in Patients With Chronic Hepatitis C Genotype 1 or 4

Start date: February 2010
Phase: Phase 2
Study type: Interventional

This equally randomized (1:1), double-blind, parallel arm study will assess the safety and antiviral efficacy of RO5024048 added to standard Pegasys (peginterferon alfa-2a) plus Copegus (ribavirin) therapy in patients with chronic hepatitis C genotype 1 or 4. Patients in arm A will receive RO5024048 (1000mg orally twice daily) for 24 weeks in addition to Pegasys (180 micrograms sc weekly) and Copegus (1000mg or 1200mg orally daily). Patients achieving a rapid virological response (RVR) at week 4, sustained through week 22, will stop all treatment at week 24; non-RVR patients will continue treatment with Pegasys and Copegus for another 24 weeks up to week 48. Patients in arm B will receive standard treatment with Pegasys (180 micrograms sc weekly) and Copegus (1000mg or 1200mg orally daily) for 48 weeks. Anticipated time on study treatment is up to 48 weeks. Target sample size is <200.

NCT ID: NCT01055821 Completed - Clinical trials for Chronic Hepatitis C Infection

Efficacy of the Therapeutic Vaccine TG4040 Combined With Pegylated Interferon and Ribavirin in Chronic HCV Patients

HCVac
Start date: May 2010
Phase: Phase 2
Study type: Interventional

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.

NCT ID: NCT01054742 Completed - Hepatitis C Clinical Trials

Observational Study of Patients With Chronic Hepatitis C Virus (HCV) Infected With HCV Genotype 1 Low Virus Load (LVL 1) and Effect of PegIntron Plus Rebetol Treatment (Study P04793 Part 2)

Start date: December 2009
Phase: N/A
Study type: Observational

The purpose of this observational study was to provide summary data from participants who relapsed at the end of the follow-up phase after 24 weeks of treatment with standard care PegIntron plus ribavirin in Part 1 of the study (NCT00709228) and who then received retreatment during Part 2 of the study. Relapse was defined as having a positive virology result at the Week 24 post-treatment follow-up, after a negative result at the Week 24 end-of-treatment time point. Hepatitis C Virus Ribonucleic Acid (HCV-RNA) levels were measured at Day 1 and Weeks 12, 24, and 48 of the extension, and at Follow-up Week 24.

NCT ID: NCT01054729 Completed - Hepatitis C Clinical Trials

Dose-Ranging Study of Sofosbuvir in Combination With Pegylated Interferon and Ribavirin in Treatment Naïve GT 1 HCV Patients

Start date: January 2010
Phase: Phase 2
Study type: Interventional

Participants with genotype 1 HCV infection were randomized to 1 of 3 sofosbuvir doses (100 mg, 200 mg, or 400 mg) or matching placebo once daily based upon stratification for IL28B status (CC or CT/TT). Placebo tablets were administered to participants receiving 100 mg active sofosbuvir (3 placebo tablets) and 200 mg active sofosbuvir (2 placebo tablets) in order to maintain the study blind. Participants received sofosbuvir/matching placebo from Day 0 to 27. Participants also received treatment with PEG+RBV starting on Day 0 of the study which continued for 48 weeks. Participants were evaluated for sustained virologic response (SVR) for an additional 24 weeks following completion of study treatment.
