Study to Asses DTPw-HBV/Hib at 15-18 Months (m) and Mencevax™ ACW at 24 to 30 m in Primed Subjects

2014-08-27 03:45:08 | BioPortfolio


The purpose of this study is to assess the safety and reactogenicity of a booster dose of diphtheria-tetanus-whole cell pertussis-hepatitis B virus/Haemophilus influenzae type b vaccine (DTPw-HBV/Hib) at 15-18 m and to assess the immunogenicity, safety, and reactogenicity of a dose of Mencevax™ Group A, C and W135 polysaccharide meningococcal vaccine (ACW) at 24 to 30 m in primed subjects.

The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.


This open study will have two parallel groups based on the vaccination received in the primary study: AC primed Group: primed with Tritanrix™-HepB/Hib-MenAC vaccine and AC unprimed Group (control): primed with Tritanrix™-HepB/Hiberix™ vaccine. All subjects will receive a booster dose of Tritanrix™-HepB/Hiberix™ vaccine at 15 to 18 months of age with GSK Biological's OPV vaccine given concomitantly and a dose of Mencevax™ ACW vaccine at 24 to 30 months of age. Blood sampling will be done prior to (pre) and one month after (post) the Mencevax™ ACW vaccine administration for immunogenicity analyses. The study will last minimum 7 to maximum 16 months per subject.

Mencevax™ ACWY was changed to Mencevax™ ACW throughout the posting to correct an inconsistency in the earlier version of the protocol posting and to reflect the actual situation.

Medical and Biotech [MESH] Definitions

The formaldehyde-inactivated toxin of Corynebacterium diphtheriae. It is generally used in mixtures with TETANUS TOXOID and PERTUSSIS VACCINE; (DTP); or with tetanus toxoid alone (DT for pediatric use and Td, which contains 5- to 10-fold less diphtheria toxoid, for other use). Diphtheria toxoid is used for the prevention of diphtheria; DIPHTHERIA ANTITOXIN is for treatment.

A combined vaccine used to prevent infection with diphtheria and tetanus toxoid. This is used in place of DTP vaccine (DIPHTHERIA-TETANUS-PERTUSSIS VACCINE) when PERTUSSIS VACCINE is contraindicated.

An antitoxin produced against the toxin of CORYNEBACTERIUM DIPHTHERIAE that is used for the treatment of DIPHTHERIA.

A vaccine consisting of DIPHTHERIA TOXOID; TETANUS TOXOID; and whole-cell PERTUSSIS VACCINE. The vaccine protects against diphtheria, tetanus, and whooping cough.

A localized infection of mucous membranes or skin caused by toxigenic strains of CORYNEBACTERIUM DIPHTHERIAE. It is characterized by the presence of a pseudomembrane at the site of infection. DIPHTHERIA TOXIN, produced by C. diphtheriae, can cause myocarditis, polyneuritis, and other systemic toxic effects.
