BASEL, Switzerland, May 6, 2008 - New Phase III data for
Menveo® (MenACWY-CRM) show that the vaccine produced a greater
immune response against meningococcal serogroups A, C, W-135 and Y
in adolescents 11-18 years of age compared to Menactra®.
Infection with any of these four vaccine-preventable serogroups can
lead to bacterial meningitis, an infection of the membrane around
the brain and spinal cord, or sepsis, a serious infection of the
Results of this first head-to-head trial of Menveo compared to Menactra, show that
adolescents who were immunized with Menveo generated higher levels of antibodies
against all four serogroups2.
Notably for serogroup Y, among adolescents with low levels of immunity at the time of
vaccination, 81% of subjects receiving Menveo generated a protective immune response vs.
54% with Menactra2, as measured by the hSBA assay. Serogroup Y causes approximately
39% of meningococcal disease cases in the US3.
“To protect children against all major serogroups of meningococcal disease, we need
vaccines that provide broad coverage and that can be used in all at-risk age groups,” said
Keith S. Reisinger, MD, MPH, Medical Director, Primary Physicians Research, Inc.
Pittsburgh, PA. ”These data are encouraging because they show that Menveo may provide
greater protection for the more than 8 million infants and adolescents in the US against
these four vaccine-preventable serogroups than the currently available vaccine.”
Menveo is an investigational quadrivalent meningococcal conjugate vaccine in Phase III
clinical development by Novartis Vaccines. The data were presented at a late-breaker
platform session on May 5 during the 2008 Pediatric Academic Societies (PAS) Annual
Meeting in Honolulu, Hawaii.
Meningococcal disease, a leading cause of bacterial meningitis, is a rare but contagious and
potentially life-threatening infection. Infants and adolescents have the highest rates of
disease4a, which can be fatal. Each year approximately 1,400 to 2,800 cases of disease
occur in the US4b, and about 10-14 percent of patients die4c. The currently available
vaccines are not licensed for use in infants, in whom the highest rates of meningococcal
disease are observed. Phase II data published in the January 9, 2008, issue of the Journal of
the American Medical Association demonstrated Menveo to be the first meningococcal
vaccine to produce a strong immune response in infants5.
The US Centers for Disease Control and Prevention (CDC) recommends routine
immunization with a quadrivalent meningococcal conjugate vaccine for all adolescents 11-
18 years of age, college freshmen living in dormitories and people in other high risk groups
who are two to ten or 19 to 55 years of age6,7.
“The patient need for vaccines for meningococcal disease remains substantial. We appear
to be quickly realizing our goal of providing broad coverage against all serogroups of
meningococcal disease across all age groups,” said Joerg Reinhardt, CEO of Novartis
Vaccines and Diagnostics. “Given the broad range of age groups this vaccine is expected to
protect, Menveo could truly fulfill an unmet need in the meningitis vaccine market.”
This Phase III trial involved more than 2,100 11-18 year olds who received a single
vaccination with either Menveo or Menactra. One month after vaccination, geometric
mean titers (a measure of immune response) for Menveo vs. Menactra were: serogroup A,
29 vs. 18; serogroup C, 59 vs. 47; serogroup W-135, 87 vs. 44; and serogroup Y, 51 vs.
18. Additionally, the percentage of participants who achieved a protective immune
response, determined by a human serum bactericidal antibody titer (hSBA) > 1:8, with
Menveo vs. Menactra was: serogroup A, 75% vs. 67%; serogroup C, 84% vs. 84%;
serogroup W-135, 96% vs 88%; and serogroup Y, 88% vs. 69%. Similar results were
seen in the large subset of sero-negative participants, who are the participants without any
natural immunity to the bacteria before vaccination. The hSBA assay measures the body’s
protective immune response to the meningococcus based on the ability of antibodies to kill
These data build on previous studies that demonstrated Menveo generates a strong
protective immune response against these four vaccine-preventable serogroups in people
across age groups from infancy to adulthood. Novartis expects to submit a Biologics
License Application (BLA) to the US Food and Drug Administration later this year.
Menveo is currently in multiple Phase III clinical trials involving infants, young children,
adolescents and adults. The vaccine is based on the same technology Novartis pioneered to
produce Menjugate®, a meningococcal serogroup C conjugate vaccine approved outside
the US since 2000 for use in individuals from two months of age through adulthood.
Novartis is a global leader in providing vaccines to protect against the deadly
meningococcal disease. In addition to developing Menveo, Novartis has already distributed
more than 26 million doses of Menjugate around the world and produced MenZB®, a
vaccine against a strain of meningococcus B specific to a recent outbreak in New Zealand.
Novartis is also developing a recombinant vaccine to provide broad coverage against
multiple strains of serogroup B, for which no vaccine is currently available.
About meningococcal disease, a leading cause of bacterial meningitis
Meningococcal disease can manifest as bacterial meningitis – an infection of the
membranes around the brain and spinal cord – or sepsis, a bloodstream infection. It is
caused by the bacterium Neisseria meningitidis (N. meningitidis). The symptoms – which
can include sudden onset of fever, rash, headache, and stiff neck – can progress rapidly.
Even with early and appropriate treatment, some cases are fatal4b, typically within 24-48
hours8. For those who survive, as many as 19 percent suffer serious long-term
consequences such as deafness, neurological damage or limb loss4d.
