* Meningococcal disease is a major cause of bacterial meningitis and sepsis with high consequent disability and mortality rates worldwide
* Dominant groups of meningococcal disease vary by country and region, and can change over time, making it an even more unpredictable disease
* Menveo helps protect against four of the five major bacterial groups responsible for meningococcal disease
* One year after vaccination, more adolescents maintained protective immune response against three of the four groups when immunized with Menveo than with polysaccharide vaccine
Basel, SWITZERLAND | March 18, 2010 | Novartis announced today that the European Commission (EC) granted a Marketing Authorization for Menveo® (Meningococcal Group A, C, W135 and Y conjugate vaccine) in all 27 European member states. Menveo is indicated for the active immunization of adolescents (from 11 years of age) and adults at risk of exposure to Neisseria meningitidis groups A, C, W135 and Y, to prevent invasive disease. Menveo is the first conjugate vaccine commercially available in Europe that helps protect against four major groups of meningococcal disease. Novartis intends to submit additional data to the European Medicines Agency to support the use of Menveo in other age groups.
Meningococcal infection is a leading cause of bacterial meningitis - an infection of the membrane around the brain and spinal cord - and sepsis - a bloodstream infection,. Meningococcal disease progresses rapidly and can lead to death within 24-48 hours of the first symptoms. Of those who survive, as many as one in five will suffer life-long complications such as brain damage, learning disabilities, hearing loss and limb loss.
"Marketing approval for Menveo for people ages 11 and older is the culmination of 10 years of dedicated effort by Novartis Vaccines to provide a vaccine that can help protect against meningococcal disease," said Andrin Oswald, Division Head of Novartis Vaccines and Diagnostics. "Our priority is to advance the fight against meningitis through innovative vaccines that help save lives."
The majority of all meningococcal disease cases around the world can be attributed to five main groups - called serogroups - of the bacteria that cause meningococcal disease, Neisseria meningitidis. Importantly, dominant groups of meningococcal disease can vary by country and region, and change over time, making it an even more unpredictable disease. The most effective way to prevent this deadly disease is through the use of a vaccine that offers protection against as many bacterial groups as possible.
Adolescents and young adults are at increased risk of contracting meningococcal disease, often because they start to encounter new situations and undergo changes in their lifestyles,. Other groups at increased risk of contracting meningococcal disease include travelers, military personnel and Muslim pilgrims traveling to the Hajj or Umrah.
Menveo was developed using conjugate technology, which was pioneered by Novartis Vaccines in the development of its meningococcal group C conjugate vaccine, Menjugate®. A conjugate vaccine is developed by attaching a polysaccharide antigen - the key component of a vaccine that prompts the body to respond to infection - to a carrier protein in order to enhance the body's immune response to the vaccine.
When utilized in a national immunization program, conjugate vaccines (such as those designed to help protect against Hib, pneumococcal and meningococcal group C disease) have reduced the number of people (both vaccinated and unvaccinated) who carry the bacteria that cause the disease. Novartis is currently studying the long-term safety and immunogenicity of Menveo, and is considering clinical studies on carriage.
Menveo has been administered to more than 18,500 people and is currently in multiple Phase III clinical studies in infants and toddlers worldwide. The U.S. Food and Drug Administration (FDA) recently approved Menveo for use in 11-55 year olds.
Marketing Authorization was based on data from a pivotal Phase III clinical trial and a non-inferiority study. In the non-inferiority study, immune response was assessed among adolescents 11-17 years of age. Menveo was shown to be non-inferior to a quadrivalent meningococcal polysaccharide vaccine (ACWY-PS) for all four meningococcal groups contained in the vaccine. At one year after vaccination, a higher proportion of adolescents who received Menveo had maintained a protective immune response against three of the four meningococcal groups (groups C, W135 and Y) than those who received ACWY-PS. Further, when evaluated in adults 56-65 years of age, Menveo was shown to be non-inferior to ACWY-PS in all four meningococcal groups contained in the vaccine and statistically superior for groups A and Y. The clinical significance of these findings is unknown.
Achieving and maintaining an immune response in adolescents is considered important because they are particularly susceptible to meningococcal disease and are more likely to carry the bacteria than other age groups. In addition, adolescents and young adults have relatively high death rates from meningococcal infection. A study in the United States found that nearly a quarter of meningococcal infections in 15- through 24-year-olds were fatal.
"Meningitis often develops without warning, and progresses rapidly, making it a particularly dangerous disease,," said Chris Head, Chief Executive of the Meningitis Research Foundation, UK. "Awareness of symptoms, understanding treatment and, above all, prevention with a vaccine that helps to protect against multiple groups of bacteria will help save lives and prevent devastating, lifelong after-effects."
About meningococcal disease
Most cases of meningococcal disease occur in previously healthy people without any warning. Even small changes in lifestyle - such as going out to clubs, travelling, smoking, going to college or military duty - can increase the likelihood to become a carrier of meningococcal bacteria and the chance of a person contracting meningococcal disease. The World Health Organization (WHO) and several national governments recommend the use of meningococcal vaccination for people considered to be at increased risk for developing meningococcal disease, such as adolescents, travelers to areas known for outbreaks, military personnel and Muslim pilgrims travelling to the Hajj or Umrah,.
Because the initial symptoms of meningococcal disease can be non-specific and flu-like, it can be difficult for health care professionals to diagnose early. Classic symptoms, such as neck stiffness and petechial rash, do not appear until relatively late in the illness - 13 to 22 hours after the first symptoms appear.
According to the WHO, approximately 5-10 percent of those who contract meningococcal disease will die, even if they are diagnosed and receive treatment. Of those who survive meningococcal disease, as many as one in five will suffer life-long complications, such as brain damage, learning disabilities, hearing loss and limb loss.
Infants are the most vulnerable population and represent the greatest unmet need. About 6-10 percent of children under 12 months of age who contract meningococcal disease will die.
About Novartis Vaccines' global meningococcal franchise
Menveo vaccine is based on the same proprietary technology Novartis Vaccines pioneered to produce Menjugate®, a meningococcal serogroup C conjugate vaccine approved outside the U.S. since 2000 for use in individuals from 2 months of age through adulthood. The company has already distributed more than 41 million doses of Menjugate around the world. Novartis also produced MenZB®, a vaccine against a strain of meningococcus B specific to an outbreak in New Zealand.
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 protein vaccine for its potential to provide broad coverage against multiple strains of serogroup B, for which no vaccine is currently available.
Important Safety Information
Menveo is indicated for active immunization of adolescents (from 11 years of age) and adults at risk of exposure to Neisseria meningitidis groups A, C, W-135 and Y, to prevent invasive disease.
Menveo should not be administered to individuals with known hypersensitivity to any component of Menveo or other meningococcal vaccines, or other vaccines containing derivatives of Corynebacterium diphtheriae. Because of the risk of hematoma, Menveo should not be administered to individuals with any bleeding disorder, such as hemophilia or thrombocytopenia, nor to persons receiving anticoagulant therapy, unless the potential benefit outweighs the risk of administration. Menveo should not be administered to people who have an acute severe febrile illness, although a mild fever of short duration is not a contraindication. Due to the absence of supporting data, the decision to administer Menveo to pregnant women should be evaluated according to the risk of meningococcal infection.
The most common local adverse reactions to Menveo include injection site pain, erythema, and induration. The most common systemic adverse reactions include headache, myalgia, malaise, nausea, arthralgia, chills, rash and fever. Some reactions may be severe.
Vaccination with Menveo may not protect all individuals. Patients who are immunocompromised or receiving immunosuppressive therapy may have an inadequate response to vaccination.
Before administering Menveo, please see full Prescribing Information.
