The International Vaccine Institute
� The world’s only legally constituted International Research Organization dedicated exclusively to research on new vaccines for the world’s poorest people
� Established by treaty (40 countries and WHO) in 1997 as a result of an international competition overseen by UNDP
� Priority to enteric diseases, respiratory infections, and Flaviviruses (Dengue and Japanese encephalitis)
� Over 120 staff and an annual budget over $20 million

DVI does not directly support R&D but
rather undertakes parallel and
supportive programs to development.

DVI and IP
� We do not have enough resources to directly control IP
� Want to understand IP environment and then take appropriate actions to influence access by the poor.
� Want to encourage competitive environment to obtain affordable prices.
– Do multiple developers have Freedom to Operate
� To conduct R&D?
� To market in developing countries?
![Page 7: IP and Dengue Vaccines: A case study - World Trade … · · 2011-02-23Joint Technical Symposium by WHO, WIPO and WTO on Access to Medicines, Patent Information and Freedom to Operate](https://reader034.vdocuments.net/reader034/viewer/2022051601/5aca2ad47f8b9aa3298d686d/html5/thumbnails/7.jpg)
Result: Do the sponsors have Freedom to Operate in development?
� Each sponsor seems to have all the IP needed to bring its vaccine candidate to regulatory agency approval and to market widely.
� This is quite different from some other PDPs, e.g. malaria vaccines, where there is a patent thicket.

Activities of U.S. NIH
� Scientists developed vaccine candidate through Phase 1
� NIH has obtained many patents but not filed in developing countries
� Access to materials. NIH will supply clones only to licensees and only in accordance with terms of license, i.e. geographic limitations.
� DVI strongly endorses this IP management policy because it allows participation of developing country manufacturers – a proven source of high quality, low cost vaccines.

Delivery patents
� Dengue is caused by four viruses (DEN1-4) and a vaccine must be tetravalent
� However, the vaccine viruses interfere with each other in the vial (and in the person)
� Vialing separately (e.g. 2 X 2) could reduce problem.
� Patent applications protect such procedures for all vaccines.

Dengue Vaccine – only a LMIC market
� Companies can market to the private sector which appears very attractive
� Companies must market to public sector, but what determines price?
� Because we cannot control IP directly, DVI will publish detailed cost of goods studies
![Page 12: IP and Dengue Vaccines: A case study - World Trade … · · 2011-02-23Joint Technical Symposium by WHO, WIPO and WTO on Access to Medicines, Patent Information and Freedom to Operate](https://reader034.vdocuments.net/reader034/viewer/2022051601/5aca2ad47f8b9aa3298d686d/html5/thumbnails/12.jpg)
Summary
� No significant IP limitations to development
� No significant IP limitations to market
� DVI strategy for access
– Promote developing country producers
– Rely on “market realities”
– Publish cost of production studies
– Monitor IP landscape

Overall Conclusion
� IP is only one factor influencing access in developing countries.
� Others are – Multiple manufacturers, esp. in developing
countries
– Market realities – requirement to meet public health needs
– Regulatory pathways
– Knowledge about cost of goods
