(6th November, 2014); After successful 3rd clinical trial of Denue vaccine, Sanofi will file for registration of its vaccine candidate and, subject to regulatory approval, the world’s first dengue vaccine could be available in the second half of 2015.

Dengue is a threat to over 2.5 billion people, nearly half the world’s population , and is a pressing public health priority in over 100 countries in the Americas and in Asia. Every year, an estimated 500,000 people, including children, are hospitalized due to severe dengue, which put s a huge strain on health care systems particularly during outbreaks. Dengue has dramatically increased over the past 30 years with an acceleration over the last decade due to travel and urbanization .

Sanofi Pasteur, the vaccines division of Sanofi, announced the publication of the detailed results of the final landmark phase III clinical efficacy study in Latin America in The New England Journal of Medicine. Overall efficacy against any symptomatic dengue disease was 60.8 percent in children and adolescents 9 - 16 years old who received three doses of the vaccine. Analyses show a 95.5 percent protection against severe dengue and an 80.3 percent reduction in the risk of hospitalization during the study. The results of this second phase III efficacy study confirm the high efficacy against severe dengue and the reduction in hospitalization observed during the 25 - month active surveillance period of the first phase III efficacy study conducted in Asia, highlighting the consistency of the results across the world.

Safety analyses (solicited reactions, unsolicited events and Serious Adverse Events SAEs) during the study showed similar reporting rates between the vaccine and control groups and are consistent with the favorable safety profile observed during the 25 - month active surveillance period of the previous efficacy study conducted in Asia. The full data of the Latin American study are also presented at the American Society of Tropical Medicine and Hygiene (ASTMH) Annual Meeting, 2 - 6 November 2014.

“We plan to submit the vaccine for licensure in 2015 in endemic countries where dengue is a public health priority,” said Olivier Charmeil, President and CEO of Sanofi Pasteur. “We are committed to supporting countries’ ambitions to significantly impact the human and economic burden of dengue through compreh ensive vaccination programs. Our goal is to help meet the WHO’s objectives to reduce dengue mortality by 50% and morbidity by 25% by 2020.”

Sanofi Pasteur is already producing the vaccine in a newly dedicated production facility in Neuville-sur-Saône, France, which will be capable of providing timely supply of large quantities of vaccines to meet the global public health demand.

Sanofi Pasteur has been working on a dengue vaccine for more than 20 years. The company’s goal is to make dengue the next vaccine - preventable disease with a safe and effective dengue vaccine accessible in all regions of the world where dengue is a public health issue. The company is committed to support the WHO’s ambition to reduce dengue mortality by 50 percent and morbidity by 25 percent by 2020.
