NCT ID: NCT00249860 Completed - Hepatitis C Clinical Trials

A Multicenter Phase 3 Study of Interferon-beta-1a for the Treatment of Chronic Hepatitis C in Asian Subjects

Start date: September 2002
Phase: Phase 3
Study type: Interventional

The main objective of this study is to establish interferon-beta-1a as the treatment of choice for chronic Hepatitis C with better efficacy and safety profiles in monotherapy or combination therapy. This will be a multicenter, randomized, double-blind, placebo-controlled study with a placebo to be crossed-over to a combination of interferon-beta-1a and ribavirin or no treatment during an open-label extension phase. The duration of the trial will be 48 weeks, with a double-blind period of 12 weeks. The study will recruit 257 eligible subjects of either sex. It will be conducted by approximately 16 Investigators / investigational centers in 3 countries (China, Hong Kong and Singapore).

NCT ID: NCT00248339 Completed - Hepatitis C Clinical Trials

Trial of Peg-interferon Plus Epoetin-alfa for Treatment of Chronic Hepatitis C Virus Infection

Start date: May 2002
Phase: Phase 3
Study type: Interventional

The purpose of this study is to determine if the use of epoetin-alpha will allow patients with chronic hepatitis C virus infection to be treated with higher doses of peginterferon-alpha-2b and ribavirin, thus increasing chances at lower viral levels and raising sustained virologic response.

NCT ID: NCT00246363 Completed - HIV Infections Clinical Trials

A Clinical Research Study Designed To Determine If Treatment of Hepatitis C With Milk Thistle is More Effective Than No Treatment In Patients Infected With Both HIV And Hepatitis C

Start date: January 2005
Phase: Phase 1/Phase 2
Study type: Interventional

There is some information available that indicates that Milk Thistle is an effective treatment for liver disease. This study will compare Milk Thistle with a placebo, (a medicine that looks just like Milk Thistle but does not contain any Milk Thistle) to see if people with both Hepatitis C and HIV infections show improvement or cure of Hepatitis C. The study will last one year.

NCT ID: NCT00245414 Completed - Chronic Hepatitis C Clinical Trials

Trial of Pegasys® in Patients With Chronic Hepatitis C

Start date: October 2005
Phase: Phase 4
Study type: Interventional

The purpose of this study is to investigate the efficacy and safety of Pegasys® 180μg for subcutaneous (s.c.) injection in interferon (IFN)-treated or IFN-untreated chronic hepatitis C patients except for those infected with genotype 1b of hepatitis C virus (HCV) and a high viral load (≥ 100 KIU/mL). In addition, this study will explore the efficacy and safety of Pegasys® 180μg for s.c. injection given at 2 different periods between 24 and 48 weeks in IFN-untreated chronic hepatitis C patients.

NCT ID: NCT00244374 Completed - Hepatitis C Clinical Trials

A Randomized Trial of Vaccine Adherence in Young Injection Drug Users

UFO VAX
Start date: August 2004
Phase: N/A
Study type: Interventional

The purpose of this study is to compare the effects of (a) immunization setting and (b) outreach worker support on young injection drug users' (IDU) adherence to a multiple dose immunization schedule with a combined hepatitis A virus (HAV) inactivated and hepatitis B virus (HBV) recombinant vaccine.

NCT ID: NCT00241618 Completed - Hepatitis C Clinical Trials

Timing and Duration of Acute Hepatitis C Treatment

Start date: January 2002
Phase: Phase 4
Study type: Interventional

Spontaneous resolution of acute hepatitis C infection cannot be predicted and the majority of cases persist and become chronic. This randomized trial assesses the efficacy and safety of peginterferon alfa-2b. The investigators hypothesize that therapy strategies could prevent the development of chronic hepatitis.

NCT ID: NCT00240539 Completed - Hepatitis B Clinical Trials

Long Term Follow-Up Study 16-20 Years After Hepatitis B Vaccination in Newborns of Mothers Who Were Seropositive for Hepatitis B Envelope Antigen (HBeAg) & Hepatitis B Surface Antigen (HBsAg)

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

This study is performed to evaluate the persistence of anti-hepatitis B surface antigen (HBs) antibodies up to 16, 17, 18, 19 and 20 years after administration of the first dose of the study vaccine, Engerix-B™. No new subjects will be recruited in this long-term follow-up study. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

NCT ID: NCT00240526 Completed - Hepatitis B Clinical Trials

LT F-up Study 16-20 Yrs After Vaccine Dose of Hepatitis B With/Without HBIg in Newborns to HBeAg+ Mothers

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

To evaluate the persistence of anti-HBs antibodies up to 16, 17, 18, 19 and 20 years after administration of the first dose of the study vaccine. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007. No additional subjects will be recruited during this long-term follow-up study and no vaccine will be administered.

NCT ID: NCT00240500 Completed - Hepatitis B Clinical Trials

Follow-up Study 16-20 Years After Primary Vaccination Against Hepatitis B of Newborns From HBeAg+ & HBsAg+ Mothers

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

The purpose of this study is to evaluate the persistence of anti-hepatitis B surface antigen (anti-HBs) antibodies 16, 17, 18, 19 and 20 years after administration of the first dose of the study vaccine. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

Comparison in Efficacy and Safety Between Interferon Alfacon-1 Alone and Concomitant Dosing With Ribavirin for the Treatment of Hepatitis C

Start date: n/a
Phase: Phase 3
Study type: Interventional

Efficacy and safety is compared between interferon alfacon-1 alone and concomitant dosing of interferon alfacon-1 and ribavirin in hepatitis C patients.
