Novartis announced that it has received approval from the US Food and Drug Administration (FDA) for the use of Menveo (Meningococcal [Groups A, C, Y and W-135] Oligosaccharide Diphtheria CRM197 Conjugate Vaccine) for active immunization to prevent invasive meningococcal disease caused by Neisseria meningitidis serogroups A, C, Y and W-135 in individuals 2 to 10 years of age. Menveo received initial FDA approval in 2010 for use in adolescents and adults from 11 to 55 years of age.
The FDA approval of Menveo for use in children 2 to 10 years of age is based on phase III trial data involving 5,297 participants in that age group. In the pivotal trial, the safety and immunogenicity of Menveo against each of the four serogroups were compared with those of the other currently US-licensed ACW-135Y meningococcal conjugate vaccine. Novartis also agreed to conduct three post marketing studies.
Separately, Novartis received a Refuse To File (RTF) letter from the FDA regarding the company's supplemental Biologics License Application (sBLA) for the use of Menveo in infants from 2 to 12 months. The sBLA had been submitted to the FDA in November 2010. Novartis plans to resubmit a sBLA in 2011 for the expanded use of Menveo in infants and toddlers from 2 months to 2 years old.
“The approval of Menveo for the use in children 2-10 years of age is another important step towards our goal to protect people of all ages against this devastating disease,” said Andrin Oswald, Division Head of Novartis Vaccines and Diagnostics. “The response from the FDA on our Menveo infant file is disappointing. We believe that concerns raised are of procedural nature and plan to resubmit the sBLA within the next few months. This will also provide us with an opportunity to supplement the file with additional clinical data that support expanded use of Menveo in infants and toddlers from 2 months to 2 years old.”
Menveo is registered in more than 40 countries for active immunization to prevent invasive meningococcal disease caused by Neisseria meningitidis serogroups A, C, W-135 and Y in people from 11 years of age. Menveo has been administered to more than 18,500 participants in clinical trials across all age groups worldwide, and studies are ongoing in infants, toddlers, adolescents and adults. Menveo received initial FDA licensure in May 2010 for use in adolescents and adults (11 to 55 years of age). Pivotal phase III data presented in October 2010 at the 48th Annual Meeting of the Infectious Diseases Society of America (IDSA) showed that Menveo induced immune responses in a high percentage of infants against four important meningococcal disease-causing serogroups (A, C, Y and W-135).
In the EU, Menveo is known as Meningococcal Group A, C, W135 and Y Conjugate Vaccine. Novartis Vaccines plans to submit additional data to the European Medicines Agency to support the use of Menveo in infants and children 0 to 10 years of age in the first half of 2011. The label extension for use in children 2 to 10 years of age has already been submitted in Canada.
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 diphtheria. Because of the risk of haematoma, with any bleeding disorder, such as haemophilia or thrombocytopenia, nor to persons receiving anticoagulant therapy, unless the potential benefit outweighs the risk of administration, 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 indurations. 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.
