NCT ID: NCT00790673 Completed - Chronic Hepatitis C Clinical Trials

A Phase 1/2 Study of CF102 in Patients With Chronic Hepatitis C Genotype 1

Start date: July 2009
Phase: Phase 1/Phase 2
Study type: Interventional

This trial will test the hypothesis that CF102 can safely and effectively suppress viral load in patients with chronic hepatitis C and high circulating levels of virus. The trial will monitor the safety of twice-daily oral dosing with CF102 over a 16-week period; will measure changes in viral load during therapy; and will measure blood concentrations of CF102 at various time points during dosing.

NCT ID: NCT00788918 Completed - Clinical trials for Major Depressive Disorder

Study of Cerebral Function in Patients With Chronic Hepatitis C Infection (HCV/CNS)

Start date: November 2008
Phase: N/A
Study type: Interventional

Patients with HCV infection often suffer from chronic fatigue, depression and reduced cognition, even before evolving severe liver fibrosis, liver cirrhosis and hepatic encephalopathy. It is currently unclear to what extent the symptoms er due to a direct pathological effects of the virus itself, or due to pre-existing psychiatric disease. There is a complex relationship between prior or existing drug abuse, psychiatric disease and HCV infection, that makes it difficult to establish cause-effect relationships. A biological mechanism has been suggested to contribute to development of cerebral dysfunction in the patients. According to the prevailing Trojan Horses hypothesis circulating lymphocytes cross the blood brain barrier carrying HCV to the central nervous system and virus is subsequently replicated in the macrophages and the microglia in brain as a separate compartment. As part of the immunological response to viral replication, neurodegenerative processes takes place with a harmful effect on the neural circuit and cerebral function. Identification of HCV RNA negative strand, a replication product, in brain tissue from HCV patients, as part of autopsy studies, supports the hypothesis. Moreover, HCV patients have also been observed with abnormal metabolic concentrations in the frontal white substance and the basal ganglia by MRI spectroscopy compared to control groups. The overall study objective is to assess cerebral function with particular emphasis on cognitive functions in HCV patients (genotypes 1,2,3 and 4) by use of a neuropsychiatric test battery. Furthermore, the patients will be examined by MRI, including magnetization transfer, diffusion tensor and contrast perfusion, in order to perform measurements of cerebral volumetric and microstructure. Finally, HCV analysis, including viral sequences and cytokine profiles, in serum and cerebrospinal fluid will be carried out in the study population.

NCT ID: NCT00787371 Completed - Hepatitis C Clinical Trials

Effect of Low-dose PegIntron on ALT Normalization in Japanese Patients With Chronic Hepatitis C (Study P04508)(COMPLETED)

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

In patients with chronic hepatitis C, the ultimate treatment goal is the improvement of liver histology and inhibition of progression to liver cirrhosis and hepatocellular carcinoma (HCC). These effects are reported to be correlated with sustained ALT improvement. Therefore, the aim of this study is to determine if a low-dose (0.25, 0.5, or 1.0 mcg/kg SC QW) PegIntron monotherapy administered for 12 weeks will result in ALT normalization in Japanese patients with chronic hepatitis C.

NCT ID: NCT00782353 Completed - Chronic Hepatitis C Clinical Trials

Safety, Tolerability, and Antiviral Activity of ANA598 in Patients With Genotype-1 Chronic HCV Infection

Start date: October 2008
Phase: Phase 1
Study type: Interventional

The purpose of this study is to investigate the safety, tolerability, and antiviral activity of ANA598 in patients with genotype-1 chronic hepatitis C infection.

NCT ID: NCT00781976 Completed - Hepatitis C Clinical Trials

Antiviral Activity of AZD7295 in HCV Carriers

Start date: November 2008
Phase: Phase 1
Study type: Interventional

PK, safety study of AZD7295 in HCV carriers

NCT ID: NCT00781274 Completed - Hepatitis C Clinical Trials

Efficacy and Safety of MP-424, Peginterferon Alfa-2b and Ribavirin in Chronic Hepatitis C Who Have Not Achieved an Undetectable HCV RNA Level With Previous Interferon Based Therapy

Start date: December 2008
Phase: Phase 3
Study type: Interventional

This study will evaluate the efficacy and safety of MP-424 with Peginterferon Alfa-2b and RBV in patients with (Genotype 1) hepatitis C, who did not respond to previous treatment.

NCT ID: NCT00780910 Completed - Chronic Hepatitis C Clinical Trials

Efficacy and Safety of MP-424, Peginterferon Alfa-2b, and Ribavirin in Patients With Chronic Hepatitis C Who Relapsed After Previous Interferon Based Therapy

Start date: November 2008
Phase: Phase 3
Study type: Interventional

This study will evaluate the efficacy and safety of MP-424 with Peginterferon Alfa-2b (PEG-IFN) and Ribavirin (RBV) in patients with (Genotype 1) hepatitis C, who relapsed after previous treatment.

NCT ID: NCT00780416 Completed - Hepatitis C Clinical Trials

Efficacy and Safety of MP-424/Peginterferon Alfa-2b/Ribavirin Combination in Treatment-Naïve Patients With Chronic Hepatitis C

Start date: November 2008
Phase: Phase 3
Study type: Interventional

This study will evaluate the efficacy and safety of MP-424 with Peginterferon Alfa-2b (PEG-IFN) and Ribavirin (RBV) in treatment-naïve patients with (Genotype 1) hepatitis C.

NCT ID: NCT00778843 Completed - Chronic Hepatitis C Clinical Trials

Antioxidant and Immunomodulator Properties of Viusid in Patients With Chronic Hepatitis C

Start date: October 2008
Phase: Phase 3
Study type: Interventional

The pathogenesis of chronic hepatitis C (CHC) is associated to severe oxidative stress and non-selective immunological disturbance that leads to necro-inflammation and progression of fibrosis. Previous trials suggested that antioxidant and inmunostimulant therapies may have a beneficial effect. The purpose of the study is to evaluate whether Viusid, a nutritional supplement with hepatoprotective properties, could ameliorate the oxidative stress and modulate the immune response in patients with CHC and non-responders to pegylated interferon plus ribavirin, during 24 weeks of treatment.

NCT ID: NCT00775125 Completed - HIV Clinical Trials

VX-950-TiDP24-C124: A Phase I Trial to Investigate the Potential Pharmacokinetic Interactions Between Telaprevir and Darunavir/Ritonavir and Between Telaprevir and Fosamprenavir/Ritonavir at Steady-state.

Start date: June 2008
Phase: Phase 1
Study type: Interventional

The primary objectives are to determine the effect of steady-state DRV/rtv 600/100 mg twice daily (b.i.d.) on the steady-state pharmacokinetics of telaprevir 750 mg every (q) 8h and 1125 mg q12h and vice versa;- to determine the effect at steady-state of fAPV/rtv 700/100 mg b.i.d. on the steady-state pharmacokinetics of telaprevir 750 mg q8h and 1125 mg q 12h and vice versa; to determine the steady-state pharmacokinetics of telaprevir 750 mg q8h versus telaprevir 1125 mg q12h, alone and during coadministration of either steady-state DRV/rtv 600/100 mg b.i.d or fAPV/rtv 700/100 mg b.i.d.
