Study of PENTAXIM™ Vaccine Versus TETRAXIM™ Vaccine Given With ACTHIB™ Vaccine in South Korean Infants.

Phase 3

Completed

• Conditions: Diphtheria; Tetanus; Pertussis; Poliomyelitis; Haemophilus Influenzae Type B

• Registration Number: NCT01214889
• Lead Sponsor: Sanofi

Brief Summary

This study is designed to assess the immunogenicity and safety of PENTAXIM™ combined vaccine versus TETRAXIM™ vaccine to support registration of PENTAXIM™ in South Korea.

Primary Objective:

To demonstrate the non-inferiority in terms of seroprotection rates (Diphtheria, Tetanus, Polio types 1, 2 and 3, Polyribosyl Ribitol Phosphate \[PRP\]) and vaccine response rates to acellular Pertussis antigens of sanofi pasteur's PENTAXIM™ vaccine versus sanofi pasteur's TETRAXIM™ and Act (Haemophilus influenzae type b) HIB™ vaccines, one month after the three-dose primary vaccination.

Detailed Description

All participants will receive three primary doses of their assigned study the vaccine, on Days 0, 60, and 120. They will be assessed for immunogenicity on Day 0 before vaccination and Day 150 post-vaccination. Safety will be assessed for all participants throughout the study, up to Day 157.
