NCT ID: NCT00366366 Completed - Hepatitis B Clinical Trials

To Evaluate Immunogenicity & Safety of GSK Bio's DTPa-HBV-IPV/Hib (Mixed Vaccine) and DTPa-IPV/Hib + HBV Vaccines

Start date: September 2001
Phase: Phase 3
Study type: Interventional

This study assessed the immunogenicity and safety of two vaccination regimens that employed either GSK Biologicals' combined DTPa-HBV-IPV/Hib vaccine or DTPa-IPV/Hib vaccine. In the two groups, infants received the DTPa-IPV/Hib vaccine at 3 and 4 months of age, as the first 2 doses of the primary vaccination course. At 5 months of age, they received either the DTPa-IPV/Hib vaccine co-administered with the HBV vaccine or a dose of the DTPa-HBV-IPV/Hib vaccine as a 3rd dose. Infants in the two groups had previously received 2 doses of HBV vaccine at birth and at 1 month of age.

NCT ID: NCT00363155 Completed - Clinical trials for Hepatitis B, Chronic

KRN7000 in Chronic Hepatitis B

Start date: March 2003
Phase: Phase 1/Phase 2
Study type: Interventional

The purpose of this trial is to determine the safety, tolerability and effectiveness of KRN7000 for chronic hepatitis B infection.

NCT ID: NCT00362700 Terminated - Hepatitis B Clinical Trials

Safety and Efficacy Study of Retreated Clevudine in Chronic HBV Patients Who Received Clevudine in L-FMAU-201

Start date: July 2003
Phase: Phase 2
Study type: Interventional

The purpose of this study is to determine the safety and antiviral activity of Clevudine, when retreated to patients previously treated with Clevudine

NCT ID: NCT00362674 Completed - Hepatitis B Clinical Trials

Durability of Antiviral Activity in Chronic HBV Patients Who Showed Complete Response in L-FMAU-301,302 or 303 Trial

Start date: June 2005
Phase: N/A
Study type: Observational

The purpose of this study is to evaluate the durability of antiviral activity in chronic hepatitis B patients who showed complete response in L-FMAU-301,L-FMAU-302 or L-FMAU-303 trial.

NCT ID: NCT00362635 Completed - Hepatitis B Clinical Trials

Compare the Efficacy and Safety of 48-week Treatment With Clevudine 30mg Versus Lamivudine 100mg for CHB Infection

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

The purpose of this study is to compare the efficacy and safety of 48-week treatment with Clevudine 30 mg qd versus lamivudine 100 mg qd for chronic hepatitis B infection.

NCT ID: NCT00362505 Terminated - Hepatitis B Clinical Trials

Safety and Antiviral Activity of Clevudine in Patients Who Have Completed the L-FMAU-301 or L-FMAU-302 Trials

Start date: June 2004
Phase: Phase 3
Study type: Interventional

The purpose of this study is to determine safety and efficacy of clevudine 10 mg qd for 24 weeks after completion of 24-week treatment with clevudine 30 mg qd with 12 weeks follow-up period

NCT ID: NCT00362427 Completed - Hepatitis B Clinical Trials

Study of PR5I, a Pediatric Combination Vaccine With Enhanced Hepatitis B Component Given Concomitantly With Prevnar®

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

PR5I, a hexavalent pediatric combination vaccine is being developed to reduce the number of injections during the first 2 years of life while providing a complete course of immunization against infection caused by H. influenzae type b, hepatitis B virus, Corynebacterium diphtheriae, Clostridium tetani, Bordetella pertussis, and poliovirus types 1, 2, and 3. Primary Objective: To evaluate immunogenicity of PR5I with the adjuvant composition enhancement to the hepatitis B component when administered concomitantly with Prevnar® Secondary Objectives: To assess the safety and immunogenicity of PR5I when administered concomitantly, or one month apart with Prevnar® or separately with licensed vaccines used for routine infant vaccination in Canada.

NCT ID: NCT00362336 Completed - Hepatitis B Clinical Trials

Comparison of DTaP-IPV-Hep B-PRP~T Combined Vaccine to CombAct-HIB® Concomitantly Given With Engerix B® Paediatric and OPV

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

The purpose of this study is to document the immunological response to the investigational hexavalent vaccine at the 6, 10, and 14 weeks schedule The primary objective is to demonstrate that the hexavalent DTaP-IPV-HB-PRP~T combined vaccine does not induce lower immune responses than CombAct-HIB® with Engerix B® Paediatric and OPV in terms of seroprotection rates to Diphtheria (D), Tetanus (T), polio, Hepatitis B (HB), and Polyribosyl ribitol phosphate (PRP), one month after a 3-dose primary series (6, 10, and 14 weeks) with no HB vaccination at birth. The secondary Objectives are: To describe the safety in terms of any adverse events in the first 28 days after each injection and any serious adverse events during the entire trial. To describe Immunogenicity after the primary series and prior to and after a booster vaccination.

Start date: July 2006
Phase: Phase 4
Study type: Interventional

Persistence of seroprotective antibody concentrations & immunological memory shown by the ability to mount a response to a challenge dose of HBV vaccine
