NCT00561080

Brief Summary

Primary objective: Immunogenicity To demonstrate that a second dose of ZOSTAVAX® elicits higher varicella-zoster virus (VZV) antibody titres than a first dose of ZOSTAVAX® whether given as a 0-1 month schedule or as a 0-3 month schedule in subjects ≥70 years of age as measured at 4 weeks post-vaccination Secondary objectives Immunogenicity

  • To summarise the VZV antibody titres at 4 weeks post-vaccination after a 1-dose regimen and 4 weeks post-vaccination after each dose of each 2-doses regimen of ZOSTAVAX®.
  • To compare the VZV antibody titres at 12 months after completion of a 1-dose regimen with the VZV antibody titres at 12 months after completion of each 2-doses regimen of ZOSTAVAX®
  • To summarise the VZV antibody titres at 24 and 36 months after completion of a 1-dose regimen and at 24 and 36 months after completion of each 2-doses regimen of ZOSTAVAX®

Outcome Measures

Primary Outcomes (1)

  • Geometric Mean Titer (GMT) of Varicella Zoster Virus (VZV) Antibodies 4 Weeks After Each Vaccination: Groups 2 and 3

    Blood samples taken at 4 weeks post each vaccination to determine the geometric mean titer (GMT) of VZV antibodies via Glycoprotein Enzyme Linked Immunosorbent Assay (gpELISA).

    4 weeks post-dose 1 (Month 1 for all groups) and 4 weeks post-dose 2 (Month 2 for Group 2 and Month 4 for Group 3)

Secondary Outcomes (22)

  • Geometric Mean Titer (GMT) of VZV Antibodies 4 Weeks After Vaccination: Group 1

    4 weeks post-dose (Month 1)

  • Geometric Mean Fold Rise (GMFR) in VZV Antibody Titres From Pre-vaccination to 4 Weeks Post-dose 1 in Groups 1, 2 and 3 and 4 Weeks Post-dose 2 in Groups 2 and 3

    Predose and 4 weeks post-dose 1 (Month 1 for all groups) and 4 weeks post-dose 2 (Month 2 for Group 2 and Month 4 for Group 3)

  • Geometric Mean Titre of VZV Antibodies 12 Months Post-last Dose

    1 year post final dose for Groups 1, 2, and 3 (Group 1: Month 12; Group 2: 13 Month 13; and Group 3: Month 15)

  • Geometric Mean Fold Rise (GMFR) in VZV Antibody Titres From Pre-Vaccination To 12 Months Post-dose 1 in Group 1 And From Pre-Vaccination To 12 Months Post-dose 2 in Groups 2 and 3

    predose 1 and 1 year post-last dose (Group 1: Month 12; Group 2: 13 Month 13; and Group 3: Month 15)

  • Geometric Mean Titre (GMT) of VZV Antibodies 24 and 36 Months Post-dose 1 in Group 1 and the 24 and 36 Months Post-dose 2 in Groups 2 and 3

    24 and 36 months post-last dose
