The Long-term Antibody Persistence of GSK Biologicals' Meningococcal Vaccine GSK134612 in Healthy Adolescents/Adults

Completed · Phase 2

Conditions studied: Infections, Meningococcal

In brief

In this study, the concentration of antibody to the vaccine one year, three and five years after vaccination in subjects who were vaccinated with GSK Biologicals' meningococcal vaccine GSK134612 and Menactra® in a previous study (whose objectives \& outcome measures are presented in a separate protocol posting with NCT number =00454909) will be evaluated. The safety and immune response to a booster dose of vaccine GSK134612 administered at 5 years post-primary vaccination and a primary vaccination of a newly enrolled group with GSK 134612 vaccine will also be evaluated.

You may qualify if…

• Persistence phase:
• A male or female who was between and including 10 and 25 years of age at the time of primary vaccination in the study with NCT number = 00454909.
• Written informed consent obtained from parents/guardian of the subject and written informed assent obtained from the subject if the subject is less than 18 years of age, or written informed consent obtained from the subject if the subject has achieved the 18th birthday.
• Healthy subjects as established by medical history.
• Having completed the active phase of the vaccination study with NCT number = 00454909.
• Booster phase:
• Written informed consent obtained from parents/guardian of the subject and written informed assent obtained from the subject if the subject is less than 18 years of age, or written informed consent obtained from the subject if the subject has achieved the 18th birthday.
• Subjects who the investigator believes can and will comply with the requirements of the protocol should be enrolled in the study.
• Healthy subjects as established by medical history and history-directed physical examination before entering into the study.
• If the subject is female, she must be of non-childbearing potential, i.e., pre-menarche, have a current tubal ligation, hysterectomy, oophorectomy or be post-menopausal, or if she is of childbearing potential, she must practice adequate contraception for 30 days prior to vaccination, have a negative pregnancy test on the day of vaccination and continue adequate contraception for 2 months after vaccination.
• Additional inclusion criterion for the naïve control group:
• A male or female between, and including, 15 and 30 years of age at the time of the vaccination.

You may not qualify if…

• Persistence phase:
• Use of any investigational or non-registered product within 30 days of each persistence time point.

• History of any meningococcal disease due to serogroup A, B, C, W-135, or Y.
• Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history.
• Administration of immunoglobulins and/or any blood products within the three months preceding each persistence time point.
• Concurrently participating in another clinical study within 30 days of each persistence time point, in which the subject has been or will be exposed to an investigational or a non-investigational product.
• Bleeding disorders, such as thrombocytopenia, or subjects on anti-coagulant therapy.
• Chronic alcohol or drug abuse.
• Subjects withdrew consent to be contacted for follow-up studies.
• Booster phase (to be checked at Year 5 for all subject, including naïve control group):
• Child in care
• Not enrolled in the Kaiser Healthcare system.

• History of any meningococcal disease.
• Any confirmed or suspected immunosuppressive or immunodeficient condition,including human immunodeficiency virus infection based on medical history and physical examination.
• Administration of immunoglobulins and/or any blood products within the three months preceding the booster vaccination or planned administration through Day 30 after vaccination.
• 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.
• Bleeding disorders, such as thrombocytopenia, or subjects on anti-coagulant therapy.
• History of chronic alcohol consumption and/or drug abuse.
• Planned administration/ administration of a vaccine not foreseen by the study protocol during the period starting 30 days before until 30 days after the day of administration of the dose of vaccine(s) with the exception of any licensed inactivated influenza vaccine.
