Clinical Trial Summary

The purpose of this Phase IIIb study is to evaluate the immunogenicity, reactogenicity & safety of GSK Biologicals' Hib-MenC vaccine (Menitorix™) when co-administered with GSK Biologicals' DTPa-HBV-IPV vaccine (Infanrix™ penta) & Wyeth's 7-valent pneumococcal conjugate vaccine (Prevenar™) in preterm infants as a 3-dose primary vaccination course during the first 6 months of life (at 2, 4, 6 months of age) and of a booster dose of Menitorix™ when co-administered with GSK Biologicals' DTPa-IPV vaccine (Infanrix IPV) and Wyeth's Prevenar in the second year of life (16-18 months of age). The control is a group of full-term infants receiving the same vaccines. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

Description:

This multicenter study is open & consists of a primary & a booster phase. The study has 2 treatment groups (Preterm & Full-term) that will receive the same vaccinations; the Full-term group will be the active control. Four blood samples will be collected from all subjects for immunogenicity analyses; 2 in the primary phase at prior to the first vaccination and one month after the third vaccination and 2 in the booster phase at prior to booster dose and one month after booster dose.
