NCT ID: NCT00894257 Completed - HIV Infections Clinical Trials

Trends in Risk Factors for Mother-to-Child Transmission of Hepatitis C Among a Southern European Population

EPIALHICE B
Start date: May 25, 2009
Phase:
Study type: Observational

According to the centres taking part in the ALHICE survey, the number of HIV-HCV co-infected women is currently decreasing. This drop was first noted in 2006 and persisted in 2007. What might have been considered a chance phenomenon during the first year (2006) was confirmed in the beginning of 2008. In view of this information, the investigators wished to ascertain the reality of this trend and to investigate its causes, by attempting to answer the following questions: - Has the prevalence of risk factors for HCV infection changed among the general population over the past 10 years? - Has the prevalence of risk factors for HCV infection changed among HIV/HCV co-infected women over the past 10 years? - Is the change in the number of co-infected women who gave birth during the past 10 years related to the prevalence of certain risk factors among this population? - Is the change in the number of co-infected women who gave birth during the past 10 years related to a decrease in certain risk factors for HCV infection among the general population? - Have changes in addictive behaviour among women of child-bearing age played a role in the decreasing number of HCV-contaminated children? Furthermore, follow-up data from HCV-infected children born during this period will provide information concerning the course of HCV infection. The objectives are to study trends in numbers of deliveries among HCV/HIV co-infected women as well as trends in risk factors for HCV infection among women of child bearing age and lastly to create a cohort of HCV infected children.

NCT ID: NCT00892697 Completed - Hepatitis C Clinical Trials

Intrahepatic HCV RNA and Telaprevir Kinetics in Hepatitis C Virus (HCV)

Start date: May 2009
Phase: Phase 2
Study type: Interventional

The purpose of this study is to determine the decline of virus in the blood and liver in patients treated with telaprevir, pegylated interferon and ribavirin. Fine Needle Aspiration (FNA) procedure will be used to repeatedly sample the liver to enhance the understanding of how the virus decays in the liver in response to treatment with anti-viral compounds and the measurement of the concentration of the drugs in the liver. FNA is an alternative procedure to core needle biopsy in its ability to repeatedly sample the liver with significantly reduced morbidity.

NCT ID: NCT00882908 Completed - Hepatitis C Clinical Trials

A Study of TMC435 in Combination With Pegylated Interferon Alp\Fa-2a and Ribavirin in Patients Infected With Genotype 1 Hepatitis C Virus Who Never Received Treatment

PILLAR
Start date: June 2009
Phase: Phase 2
Study type: Interventional

The purpose of this study is to evaluate the efficacy of 4 different regimens of TMC435 in combination with peginterferon alfa-2a (PegIFNα-2a) and ribavirin (RBV), defined as the proportion of patients with sustained virologic response at Week 72 (patients with undetectable plasma HCV RNA [less than 25 IU per mL undetectable] at the end of treatment and at Week 72), compared to the control group receiving PegIFN and RBV in combination with TMC435-matched placebo.

NCT ID: NCT00882193 Terminated - Chronic Hepatitis C Clinical Trials

Pilot Study of Betaine + Combination Antiviral Therapy for Chronic Hepatitis C Genotype 1 Non-responder/Relapsers

Start date: May 1, 2009
Phase: Early Phase 1
Study type: Interventional

This is a non-randomized, open-label study examining the safety and efficacy of betaine in addition to standard anti-viral therapy in genotype 1 hepatitis C non-responders or relapsers to previous pegylated interferon plus ribavirin. Betaine (20 gm/day) in 2 divided doses will be added to Peginterferon alpha 2a (180 mcg) plus weight-based Ribavirin (1000 or 1200 mg/day, for body weight < or > 75 kg, respectively, for 48 weeks. Patients must be diagnosed with chronic hepatitis C, genotype I, and have undergone therapy for hepatitis C with pegylated interferon plus ribavirin. Subjects will be followed for safety, tolerability, hepatitis C viral response and the effect on interferon gene signaling in peripheral blood mononuclear cells during therapy.

NCT ID: NCT00881582 Completed - Chronic Hepatitis C Clinical Trials

Peginterferon Alfa-2a Plus Ribavirin Combination Treatment in Chronic Hepatitis C Post-Renal Transplant Patients

Start date: January 2009
Phase: Phase 4
Study type: Interventional

There is a distinct lack of published literature on the effect of combination treatment of PEG-interferon and ribavirin on post-renal transplantation hepatitis C virus (HCV) patients. Small case series have been published utilizing conventional interferon and/or ribavirin and the available data is extremely preliminary in nature. A small retrospective series of patients treated with Pegylated interferon and ribavirin published recently suggests that the treatment may be safe and efficacious. Unpublished reports from a few centers within Saudi Arabia also suggest a good safety profile and reasonable efficacy from this form of combination treatment. The investigators aim to prospectively study the safety and efficacy of PEG-interferon and ribavirin combination therapy in post-renal transplant HCV-infected patients. Towards this 40 patients with histological evidence of liver disease will be recruited and the efficacy of the above medications studied. The proposed study aims to evaluate the efficacy and safety of PEG-interferon and ribavirin combination therapy in the treatment of chronic HCV in renal transplant patients in a way that will allow management of such patients in an optimized manner.

NCT ID: NCT00881036 Completed - Hepatitis B Clinical Trials

Activation of Hepatitis B Virus (HBV) in Hepatitis B Surface Antigen (HBsAg) - Negative But Hepatitis B Core Antibody (Anti-HBc) - Positive Patients

Start date: August 2006
Phase: N/A
Study type: Observational

Individuals with resolved hepatitis B, characterized as hepatitis B surface antigen (HBsAg)-negative and hepatitis B core antibody-positive, have latent hepatitis B virus (HBV) infection in their liver tissue. Cytotoxic chemotherapy and hematopoietic stem cell transplantation sometimes trigger the reactivation of latently infected HBV, resulting in de novo hepatitis B. Although de novo hepatitis B could cause acute liver failure or chronic hepatitis, an effective management strategy for de novo hepatitis B has not been well established. Risk factors and effective management for de novo hepatitis B will be clarified.

NCT ID: NCT00880763 Completed - Hepatitis C Clinical Trials

A Study of Safety and Efficacy of Vaniprevir Administered With Pegylated-Interferon and Ribavirin in Japanese Participants With Chronic Hepatitis C Infection (7009-016)

Start date: April 20, 2009
Phase: Phase 2
Study type: Interventional

The study evaluates safety and efficacy of vaniprevir (MK7009), when administered with Pegylated-Interferon (peg-IFN) and Ribavirin, in Japanese patients with Hepatitis C infection. The primary hypotheses are that 1.) the proportion of patients achieving rapid viral response (RVR) in one or more of the vaniprevir treatment groups is superior to that in the placebo group, when each is administered concomitantly with pegylated interferon (peg-IFN) α-2a and ribavirin; and 2.) vaniprevir at the studied doses is well tolerated compared with placebo, when each is administered concomitantly with peg-IFN α-2a and ribavirin for 28 days.
