NCT ID: NCT01265511 Completed - Clinical trials for Hepatitis C Infection

Study of SCY-635, Pegasys and Copegus in Hepatitis C

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

This study will examine the effectiveness of 28 days of triple combination therapy including SCY-635 with peginterferon alfa 2a and ribavirin in reducing serum HCV RNA levels. An additional 20 weeks of treatment with the currently approved standard of care will be offered to all participants. The Week 24 visit will be the last on-study visit. After the Week 24 visit, all subjects with undetectable HCV RNA will be given the option to continue treatment with standard of care for an additional 24 weeks (out to Week 48) under the care of their Principal Investigator.

NCT ID: NCT01260350 Completed - Clinical trials for Chronic Hepatitis C Infection

Open-Labeled Study of PSI-7977 and RBV With and Without PEG-IFN in Treatment-Naïve Patients With HCV GT2 or GT3

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

This study is to assess the safety and tolerability of sofosbuvir (SOF) 400 mg with and without ribavirin (RBV) and/or with and without pegylated interferon alfa-2a (PEG) in subjects with genotype 1, 2 or 3 hepatitis C (HCV) infection.

NCT ID: NCT01258686 Completed - Hepatitis C Clinical Trials

Clinical Study With Silymarin in the Patients With Chronic Hepatitis C Infection Who Failed Conventional Antiviral Therapy

Start date: November 2010
Phase: Phase 3
Study type: Interventional

The purpose of this study is to determine the effectiveness of silymarin 700 mg thrice daily and assess the safety in patients with hepatitis C virus infection compared to a placebo.

NCT ID: NCT01258101 Completed - Clinical trials for Hepatitis C, Chronic

A Study of PEGASYS (Peginterferon Alfa-2a) Plus Ribavirin in Patients With Chronic Hepatitis C (CHC), Genotype 2 or 3

Start date: May 2003
Phase: Phase 4
Study type: Interventional

This randomized, parallel arm study will evaluate the efficacy and safety of Pegasys (peginterferon alfa-2a) in combination with 2 different doses of ribavirin in patients with chronic hepatitis C, genotype 2 or 3. Patients will be randomized to 4 treatment groups receiving Pegasys (180 mcg subcutaneously weekly) for either 16 or 24 weeks with one of two doses of ribavirin (400 mg or 800 mg orally daily). The anticipated time on study treatment is 16 or 24 weeks with a 24-week follow-up.

NCT ID: NCT01257204 Completed - Hepatitis C Virus Clinical Trials

Study in Genotype 2 or 3 Patients With Chronic Hepatitis Virus Infection

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

To identify a shorter duration of antiviral therapy (12 or 16 weeks) for the combination of daclatasvir with pegylated interferon alfa-2a and ribavirin.

NCT ID: NCT01253551 Completed - Hepatitis C Clinical Trials

VX-950HEP1001 - Drug-drug Interaction Study Between Telaprevir and Raltegravir

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

The purpose of this study is to confirm the absence of a clinically relevant interaction between telaprevir and raltegravir at steady-state.Telaprevir is being investigated for the treatment of chronic hepatitis C virus infection, and raltegravir is used to treat HIV infection.

NCT ID: NCT01250743 Terminated - Hepatitis C Clinical Trials

A Pilot Study of High-Dose, Intravenous Ascorbic Acid (Vitamin C) to Treat Hepatitis C

Start date: January 2009
Phase: N/A
Study type: Interventional

The purpose of this pilot study is to learn whether high doses of ascorbic acid (vitamin c), given intravenously to patients with chronic hepatitis due to infection with the genotype 1 version of the hepatitis C virus, are safe, well-tolerated and able to reduce the amount of virus circulating in the patients' blood.

NCT ID: NCT01247194 Completed - Clinical trials for Chronic Genotype 1 Hepatitis C Virus Infection

A Phase 1b Study of PPI-461 in Patients With HCV Genotype 1

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

The purpose of the study is to assess the safety, tolerability, antiviral effects, and pharmacokinetics of PPI-461 in patients with chronic hepatitis C virus genotype 1 infection.

NCT ID: NCT01241773 Completed - Hepatitis C Virus Clinical Trials

TMC435-TiDP16-C123 - A Study in Healthy Volunteers Investigating the Pharmacokinetic Interaction Between TMC435 and the Antiretroviral Agents Efavirenz and Raltegravir

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

The purpose of this study is to investigate the effect of steady-state concentrations of TMC435 on the steady-state pharmacokinetics of efavirenz or raltegravir , and vice versa. Steady state is a term which means that the drug has been given long enough so that the plasma concentrations will remain the same with each subsequent dose. TMC435 is being investigated for the treatment of chronic hepatitis C virus (HCV) infection. Efavirenz and raltegravir are two antiretroviral drugs for treatment of human deficiency virus (HIV) infection. Pharmacokinetics (pk) means how the drug is absorbed into the bloodstream, distributed in the body and eliminated from the body.

NCT ID: NCT01241760 Completed - Clinical trials for Genotype 1 Chronic Hepatitis C

VX-950-C211 - A Dosing Regimen Study (Twice Daily Versus Every 8 Hours) of Telaprevir in Treatment-naïve Participants With Genotype 1 Chronic Hepatitis C Virus Infection

Start date: December 2010
Phase: Phase 3
Study type: Interventional

The purpose of this study is to evaluate the effectiveness of telaprevir administered twice daily versus every 8 hours in combination with Peg-IFN-alfa-2a and ribavirin in treatment-naïve participants with chronic HCV genotype 1 infection.
