Study of Two Doses of GSK Biologicals' Live Attenuated HRV Vaccine (Two Different Formulations) in Healthy Infants.
Phase 2
Completed
- Conditions
- Infections, Rotavirus
- Interventions
- Biological: Human Rotavirus Vaccine - two different formulationsBiological: PrevnarBiological: IPOLBiological: InfanrixBiological: OmniHIBBiological: Pentacel
- Registration Number
- NCT00729001
- Lead Sponsor
- GlaxoSmithKline
- Brief Summary
This is a dose exploration study to assess the safety and immunogenicity of two doses of the candidate HRV vaccine at different virus concentrations in the target age group (infants approximately 2 months of age and previously uninfected with human rotavirus) and receiving concomitant administration of routine vaccinations. The study also aims at exploring the effect of unrestricted feeding on the immunogenicity of the vaccine.
- Detailed Description
All subjects enrolled from Eastern United States and Eastern Canada will continue their participation in the pilot efficacy follow-up (pilot efficacy subset).
The third dose of IPV vaccine (IPOL) may be given at visit 3, 4 or another time, at the investigator's discretion.
Comvax may be given in place of OmniHIB/ActHIB at Visit 1 and Visit 2 and the third dose of Comvax administered according to the prescribing information.
