IMMUNOGENICITY FOR MENVEO 1-VIAL PRESENTATION


MENVEO is approved in 2 presentations1:

  • 1-vial presentation for use in individuals 10 through 55 years of age
  • 2-vial presentation for use in individuals 2 months through 55 years of age

Please see the Dear Healthcare Provider Letter for a summary of the differences between the MENVEO 1-vial and 2-vial presentations.

Immunogenicity of MENVEO 1-Vial Presentation vs MENVEO 2-Vial Presentation

  • Primary objective2: To demonstrate noninferiority of MENVEO 1-vial presentation compared to MENVEO 2-vial presentation, as measured by the hSBA GMTs directed against N. meningitidis serogroup A at 1 month postvaccination
  • Primary endpoint2: Noninferiority of immune response against MenA as a measure of the between-group ratio of hSBA GMTs at 1 month postvaccination

GMT Ratios at 28 Days Postvaccination in Patients Aged 10-40 Years2

MENVEO 1-vial presentation: GMT Ratios at 28 Days Postvaccination in Patients Aged 10-40 Years
MENVEO 1-vial presentation: GMT Ratios at 28 Days Postvaccination in Patients Aged 10-40 Years

Primary endpoint noninferiority criterion: lower limit of the 2-sided 95% CI for the between-group hSBA GMT ratio against serogroup A >0.5 at 1 month postvaccination.1,2

Noninferiority of responses for serogroups C, W, and Y was not tested, although the lower limits of the 2-sided 95% CI were above the noninferiority threshold in each case.1

Study Design

The immunogenicity of MENVEO 1-vial presentation was evaluated in an observer-blind, randomized, multicenter, controlled clinical trial in individuals aged 10 to 40 years. The study compared the immune response of MENVEO 1-vial presentation to MENVEO 2-vial presentation.1,2
