NCT ID: NCT00421434 Completed - Chronic Hepatitis C Clinical Trials

Study of Nitazoxanide, Peginterferon, and Ribavirin Combination Therapies in the Treatment of Chronic Hepatitis C

STEALTHC-1
Start date: June 2006
Phase: Phase 2/Phase 3
Study type: Interventional

The purpose of this study is to evaluate the safety and efficacy of nitazoxanide-peginterferon and nitazoxanide-peginterferon-ribavirin combination regimens compared to the standard of care (peginterferon-ribavirin) in treating chronic hepatitis C genotype 4. The study will also evaluate the effect of the studied treatment regimens on end of treatment virologic response, ALT normalization and safety parameters.

NCT ID: NCT00420784 Completed - Hepatitis C Clinical Trials

A Study of Telaprevir (VX-950), Pegasys and Copegus in Hepatitis C (PROVE3)

Start date: February 2007
Phase: Phase 2
Study type: Interventional

The PROVE3 trial is a partially double blinded, randomized, Phase 2 research study of an investigational drug, Telaprevir (VX-950) or Placebo, with Pegylated Interferon Alfa 2a (Peg-IFN-alfa-2a, Pegasys®), and Ribavirin (RBV, Copegus®) in people with genotype 1 hepatitis C who have not achieved a Sustained Viral Response (SVR) with a previous treatment of interferon therapy.

NCT ID: NCT00418639 Completed - Chronic Hepatitis C Clinical Trials

Study of Nitazoxanide in the Treatment of Chronic Hepatitis C

Start date: February 2005
Phase: Phase 2
Study type: Interventional

This study will evaluate the effect of treatment with 24 weeks nitazoxanide monotherapy on end of treatment virologic response, sustained virologic response, reduction of quantitative serum HCV RNA, changes in ALT and safety parameters.

NCT ID: NCT00418054 Completed - Chronic Hepatitis C Clinical Trials

Study of Nitazoxanide Combined With Peginterferon Compared to Peginterferon Monotherapy in the Treatment of Hepatitis C

Start date: December 2005
Phase: Phase 2
Study type: Interventional

The purpose of this study is to evaluate the safety and efficacy of nitazoxanide-peginterferon alfa-2b combination therapy compared to peginterferon monotherapy in patients that are treatment naive or pre-treated for 24 weeks with nitazoxanide monotherapy in the treatment of chronic hepatitis C.

NCT ID: NCT00412334 Completed - Clinical trials for Hepatitis C, Chronic

SYREN Study: A Study of PEGASYS (Peginterferon Alfa-2a (40KD)) Plus Copegus (Ribavirin) in Non-Responder Patients With Chronic Hepatitis C (CHC) Genotype 1.

Start date: January 2007
Phase: Phase 4
Study type: Interventional

This study will evaluate the efficacy and safety of 4 regimens of PEGASYS plus Copegus, in patients with chronic hepatitis C (CHC) genotype 1 who have failed to respond to previous treatment with standard doses of PEGASYS plus ribavirin. Patients will be randomized to one of 4 groups, to receive a)PEGASYS 360 micrograms/week plus Copegus 1000-1200mg/day, b)PEGASYS 180 micrograms twice weekly plus Copegus 1000-1200mg/day, c)PEGASYS 360micrograms/week plus Copegus 1200-1600mg/day, or d)PEGASYS 180 micrograms twice weekly plus Copegus 1200-1600mg/day. Following 48 weeks treatment, there will be a 24 week period of treatment-free follow-up. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.

NCT ID: NCT00411385 Completed - Chronic Hepatitis C Clinical Trials

Efficacy of Albumin Interferon Alfa-2b With Ribavirin Compared to Peg-IFN Alfa-2a With Ribavirin in IFN Naive Patients Geno2/3

Start date: February 2007
Phase: Phase 3
Study type: Interventional

This is a phase 3, randomized, multi-center study to evaluate the efficacy and safety of albumin interferon alfa-2b (alb-IFN)in combination with ribavirin compared with peginterferon alfa-2a (PEGASYS or PEG-IFNa2a) in combination with ribavirin in subjects with chronic hepatitis C, genotype 2/3 who are IFNa treatment naive.

NCT ID: NCT00407732 Completed - Hepatitis C Clinical Trials

Overcoming Psychiatric Barriers to the Treatment of Hepatitis C

Start date: January 2007
Phase: N/A
Study type: Interventional

The purpose of this study is to develop and evaluate a 9-month psychosocial intervention that will assist patients with hepatitis C in overcoming barriers that prevent them from becoming appropriate candidates for interferon therapy.

NCT ID: NCT00403533 Completed - Hepatitis C Clinical Trials

Assessment of the Antiviral Effect of Atorvastatin on Hepatitis C Virus

Start date: February 2006
Phase: Phase 2
Study type: Interventional

We hypothesize that atorvastatin will decrease HCV viral load in patients taking the medication. Cholesterol is needed for HCV virion production. Cell culture studies have shown that atorvastatin (an HMG-CoA reductase inhibitor) decreases HCV viral replication. As atorvastatin has been proven to decrease heart attack and stroke in patients with high cholesterol, this medication is indicated for the treatment of elevated cholesterol in at risk individuals. Therefore we propose to study the effect atorvastatin has on the viral load of patients initiated on atorvastatin therapy for their elevated cholesterol.

NCT ID: NCT00402428 Completed - Chronic Hepatitis C Clinical Trials

Efficacy of Albumin Interferon Alfa-2b With Ribavirin Compared With Peg-IFN Alfa-2a With Ribavirin in IFN Naive Patients

Start date: December 2006
Phase: Phase 3
Study type: Interventional

This is a phase 3, randomized, multi-center study to evaluate the efficacy and safety of albumin interferon alfa 2b (alb-IFN)in combination with ribavirin compared with peginterferon alfa-2a (PEGASYS or PEG-IFNa2a) in combination with ribavirin in subjects with chronic hepatitis C, genotype 1 who are IFNa treatment naive.

NCT ID: NCT00401336 Completed - Hepatitis C Clinical Trials

Quantification of Liver Iron Overload and Steatosis Using Magnetic Resonance Imaging

SURFER
Start date: November 2006
Phase: N/A
Study type: Interventional

Iron excess is increasingly regarded as an important cofactor in the morbidity attributed to many disorders. Assessment of body iron stores by measurement of serum ferritin concentrations has poor specificity and the most reliable method is histological or biochemical assessment from a liver biopsy. Because liver biopsy is an invasive procedure, imaging methods have been developed to detect and quantify hepatic iron content. The aim of the study is to use a simplified magnetic resonance imaging (MRI) technique to quantify simultaneously iron and fat contents in the liver and to compare the results to the quantification obtained biochemically.
