NCT ID: NCT00774995

Last Updated: 2016-11-02

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE4
• Total Enrollment: 49 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2008-11-30
• Study Completion Date: 2010-06-30

Brief Summary

This study will evaluate the immune response of healthy subjects who received neonatal vaccination course with GSK Biologicals' Engerix™-B vaccine, approximately 20 years ago. The presence of immune memory against hepatitis B surface antigen (HBsAg) in these subjects will be investigated by the administration of a challenge dose of hepatitis B vaccine and the comparison of their antibody concentration before and one month after vaccination.

This protocol posting deals with objectives & outcome measures of the booster phase. No new subjects will be recruited during this booster phase of the study.

Eligibility Criteria

Inclusion Criteria

• Subjects who the investigator believes that they can and will comply with the requirements of the protocol should be enrolled in the study.
• A male or female who received the complete neonatal primary vaccination course of Engerix™-B in the 103860/273 primary study approximately 20 years earlier.
• Anti-HBs antibody concentrations less than the specified value at the last available follow-up time-point.
• Written informed consent obtained from the subject.
• Healthy subjects as established by medical history and clinical examination before entering into the study.
• If the subject is female, she must be of non-childbearing potential,or if she is of childbearing potential, she must practice adequate contraception for 30 days prior to vaccination, have a negative pregnancy test and continue such precautions for 2 months after completion of the vaccination.

Exclusion Criteria

• Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine within 30 days preceding the Engerix™-B challenge dose, or planned use during the study period.
• Chronic administration (defined as more than 14 days) of immunosuppressant or other immune-modifying drugs within six months prior to challenge dose administration.
• Planned administration/ administration of a vaccine not foreseen by the study protocol starting from 30 days before the challenge dose and ending 30 days after.
• Administration of a hepatitis B vaccine outside the context of this study between the follow-up time-point at which anti-HBs antibody concentrations was less than the specified value and the current challenge dose study visit.
• Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational product
• History of allergic disease or reactions likely to be exacerbated by any component of the vaccine.
• Acute disease at the time of enrolment.
• Any confirmed or suspected immunosuppressive or immunodeficient condition, including human immunodeficiency virus (HIV) infection.
• Acute or chronic, clinically significant pulmonary, cardiovascular, hepatic or renal functional abnormality, as determined by physical examination or laboratory screening tests.
• Administration of immunoglobulins and/or any blood products within the three months preceding the challenge dose visit or planned administration during the study period.
