Sanofi Pasteur Launches IMOJEV® First Single-dose Vaccine Against Japanese Encephalitis in Australia

MELBOURNE, Australia, December 9, 2012 /PRNewswire/ --
- About 3 billion people living in Asia Pacific and travellers to the region are at risk of Japanese encephalitis -
Sanofi Pasteur, the vaccines division of Sanofi (EURONEXT: SAN and NYSE: SNY), announced today that IMOJEV® vaccine against Japanese encephalitis (JE) is now available in Australia. IMOJEV® is the first single dose vaccine against JE for adults in Australia. For children, one dose of IMOJEV is recommended for primary immunization; the addition of a booster dose to extend the duration of protection is being assessed by Australian Health Authorities. IMOJEV® vaccine is licensed in Australia for people from 12 months of age and older.
About 3 billion people in the Asia Pacific Region are at risk of JE for which there is no specific treatment. In 1995 the first outbreak in Australia was identified in the islands of the Torres Strait. More recently outbreaks have also occurred in Northern Queensland. JE is the leading cause of childhood viral neurological infection and disability in Asia. JE is also a potential risk for travellers to endemic areas. Over 1.5 million Australians travel to JE endemic countries of the Asia Pacific region.
"IMOJEV® has shown to provide seroprotection to over 90% adults just 2 weeks after vaccination with one dose which provides strong motive to be vaccinated before traveling," said Joseph Torresi MD, Head of Travel Medicine at the Austin Hospital. "There is no specific treatment for JE and vaccination is the most effective way to be protected."
The Australian health authorities granted marketing authorization to IMOJEV® vaccine based on the review of clinical studies involving over 4,000 children and adults which demonstrated the safety of IMOJEV® vaccine and its ability to generate a protective immune response with one dose.
"IMOJEV® is an innovative vaccine that confers high-level protection against Japanese encephalitis with just one dose," said Russell Jacobson, General Manager of Sanofi Pasteur in Australia. "IMOJEV® makes scheduling a trip in the Asia Pacific region, or other endemic areas, more convenient for business travellers, tourists and the military alike."
About IMOJEV® vaccine
IMOJEV® vaccine is a live-attenuated JE vaccine indicated for active immunization of people 12 months and older. The clinical data supporting the use of IMOJEV® in children and in adults have been generated in multi-center studies conducted in the United States, Australia, Thailand, and the Philippines with more than 2,400 adults and 2,200 children receiving IMOJEV®. The safety and immunogenicity of IMOJEV® were compared to a licensed JE vaccine (JE-VAX®) and placebo in adults and to a control vaccine in children. A pivotal Phase III study in adults showed that a single dose of IMOJEV® is as immunogenic as three doses of JE-VAX®. A single administration of IMOJEV® elicited a protective level of neutralizing antibodies in approximately 93% and 99% of adults 14 days and 28 days after vaccine administration, respectively. Over 84% of adults were still seroprotected 5 years after vaccination . A Phase III study in children showed that approximately 95% of JE virus naive subjects were seroprotected 28 days after a single dose of IMOJEV®. The vaccine was well tolerated and there was no indication during the clinical development program of any safety concerns. The frequency of local and systemic reactions was comparable to those reported after administration of a placebo or a control vaccine.
About Japanese encephalitis
JE is caused by a virus transmitted by mosquitoes. The disease is neuro invasive with inflammation of the brain and its membranes (meninges). Most JE virus infections are mild (fever and headache) or without apparent symptoms, but up to 1 to 200 infections results in severe disease characterized by rapid onset of high fever, headache, neck stiffness, disorientation, coma, seizures, spastic paralysis and death. The case fatality rate is 30-35% among those with disease symptoms with over 15,000 deaths per year; 50% of those who survive suffer from lasting damage to the central nervous system. In areas where the JE virus is common, encephalitis occurs mainly in young children.
