DORVAL, QC, June 8 /CNW/ - Novartis Pharmaceutical Canada Inc. announced that Menveo* (Meningococcal (Groups A, C, Y and W-135) Oligosaccharide CRM197 Conjugate Vaccine), a quadrivalent meningococcal conjugate vaccine was approved by Health Canada for active immunization of adolescents (11 to 18 years of age) and adults (19 to 55 years of age) to prevent invasive meningococcal disease caused by Neisseria meningitidis serogroups A, C, Y and W-135(1).
"Meningococcal disease is particularly distressing because it can rapidly kill or debilitate previously healthy adolescents. Even with early and appropriate treatments, patients can die from meningococcal disease, often within 24 to 48 hours of onset of symptoms. This is why we welcome this new vaccinethat can prevent meningococcal disease caused by all four vaccine-preventable serogroups." says Kathryn Blain, founder and chair of the Meningitis Research Foundation of Canada (www.meningitis.ca).
"Menveo* is a welcome addition to our armamentarium in preventing this deadly disease. In the head-to-head study versus Menactra comparing the rate of protection for both vaccines that studied adolescents and adults. Menveo* demonstrated superiority for A, Y and W-135 serotypes. These results are theoretically significant given we know that circulating antibodies are necessary for protection. However, the clinical significance is not yet known" says Jay Keystone, MD, FRCPC, Professor, Department of Medicine, University of Toronto and Senior Staff Physician, Toronto General Hospital.
The National Advisory Committee on Immunization is now recommending that a dose of meningococcal conjugate vaccine be given in early adolescence, ideally around 12 years of age, even if the adolescent was previously vaccinated as part of a routine infant or toddler vaccination program. This adolescent dose is to ensure that circulating antibodies are present as adolescents enter the peak years for invasive meningococcal disease beyond infancy, which are between 15 and 24 years of age(3).
In Canada, the incidence of meningococcal disease varies, ranging between 200 and 250 cases per year(3). As many as one in 7 patients who contract meningococcal disease die from it(9). Approximately one in 5 meningococcal disease survivors suffer serious, permanent and devastating side effects, including limb amputations, seizures, paralysis, hearing loss and learning disabilities(4). Meningococcal disease is a leading cause of bacterial meningitis, which is an infection of the membrane around the brain and spinal cord, and sepsis, an often life-threatening bloodstream infection(4)(5).
Approval of Menveo* is the result of 10 years of dedicated effort by Novartis Vaccines to provide a vaccine that can help protect people against meningococcal disease. The Menveo* development program for other age groups continues in multiple Phase III clinical trials.
The Health Canada approval of Menveo* was based on a Phase III head-to-head clinical trial that compared Menveo* to the other licensed ACWY meningococcal conjugate vaccine among subjects 11 to 55 years of age. The trial, which was broken into two subsets - adolescents, age 11 to 18, and adults, age 19 to 55 - measured for each of the four serogroups both the percentage of subjects who achieved an immune response as measured by seroresponse and proportions achieving human serum bactericidal antibody (hSBA) titers greater than or equal to 1:8. Additionally the study examined antibody level as measured by geometric mean titers (GMT)(1)
In study participants aged 11 to 18 years, Menveo* met its primary endpoint for all four serogroups using hSBA seroresponse. The percentages of subjects who demonstrated an immune response (i.e., achieved an hSBA titer greater than or equal to 1:8) for each serogroup for Menveo* and its comparator (the other licensed ACWY meningococcal conjugate vaccine) respectively, were: Serogroup A - 75: 67; serogroup C - 84: 84; serogroup Y - 88: 69; and serogroup W-135 - 96: 88(1).
The seroresponse with Menveo* for serogroups A, Y and W-135, was statistically higher. However, the clinical relevance of higher post-vaccination immune responses is not known.
In the same group, the levels of circulating antibodies (i.e., GMT) in those who received Menveo* vs. those who received the comparator, respectively, were: Serogroup A - 29: 18; serogroup C - 59: 47; serogroup Y - 51: 18; and serogroup W-135 - 87: 44(1).
Menveo* will be available in Canada in the coming months.
About meningococcal disease, a leading cause of bacterial meningitis
Because invasive meningococcal disease can progress so rapidly, high levels of circulating antibodies are critical for protection. Immune memory typically takes up to five days to develop, so there often is not enough time for immune memory to mount a protective response once the disease has started(7). Five serogroups cause the majority of meningococcal disease worldwide: A, B, C, Y and W-135(8). Distribution of serogroups varies widely from geographic region to region and changes over time(9).
Currently, in Canada, most disease is caused by serogroups B, C, and Y(3). The prevalence of serogroup C is 20% followed by Y at 13% with serogroups B being the dominant serogroups at 55%. Epidemiology of meningococcal disease is constantly changing(9), so it is impossible to determine which serogroups will result in the majority of disease cases year over year.

About Novartis Vaccines' global meningococcal franchise
Novartis Vaccines is a global leader in providing vaccines to protect against deadly meningococcal disease. Through industry-leading scientific expertise, the company is focused on extending critical meningococcal vaccines research. In addition to developing Menveo* vaccine, Novartis Vaccines is developing a recombinant vaccine for its potential to provide broad coverage against multiple strains of serogroup B, for which no vaccine is currently available.
Menveo* vaccine is based on the same proprietary technology Novartis Vaccines pioneered to produce Menjugate*, a meningococcal serogroup C conjugate vaccine approved for use in Canada since 2001. The company has already distributed more than 41 million doses of Menjugate* around the world and produced MenZB(R), a vaccine against a strain of meningococcus B specific to a recent outbreak in New Zealand.

Important Safety Information
Menveo* is contraindicated in individuals who have experienced a severe allergic reaction after a previous dose of Menveo*, any component of this vaccine, or any other CRM197, diphtheria toxoid or meningococcal-containing vaccine. Appropriate medical treatment must be available should an acute allergic reaction, including an anaphylactic reaction, occur following administration of Menveo*. Vaccinees may develop syncope, sometimes resulting in falling with injury. Observation for 15 minutes after vaccination is recommended. Patients who are immunocompromised or receiving immunosuppressive therapy may have an inadequate response to vaccination. Following vaccination with a licensed meningococcal quadrivalent polysaccharide conjugate vaccine, an evaluation of post marketing adverse events suggested a potential for an increased risk of Guillain-Barré syndrome (GBS). Data are not available to evaluate the potential risk of GBS following administration of Menveo*. In clinical trials, the most frequently occurring adverse events in all subjects who received Menveo* were pain at the injection site, headache, myalgia, malaise, and nausea. Some events were severe. Safety has not been established in pregnant women. Vaccination with Menveo* may not protect all individuals.
