Nicoletta DenticoPolicy and advocacy manager
Drugs for NeglectedDiseases Initiative(DNDi)
www.dndi.org
Founded in July 2003 as a new collaborative, patients’ needs- driven,
not-for-profit drug R&D model for neglected
diseases
Our Vision• A virtual non-profit drug R&D organization to develop new
treatments against the most neglected communicable diseases
…and Mission• Primary Objective: To deliver 6 - 8 new treatments by
2014 for leishmaniasis, sleeping sickness, Chagas disease, & malaria
• Secondary Objectives: – Use and strengthen existing capacity in disease-endemic countries via
project implementation
– Raise awareness about the need to develop new drugs for neglected diseases and advocate for increased public responsibility

• World-wide spending on health R&D was never so high – Estimated at US$106bn for 2004 (GFHR, 2004)
• Since 90’s: private sector has become biggest investor

Success rate for PDPs likely to be lower(WHO CIPIH report)
• PDPs tend to seek breakthrough products rather thanincremental innovation (as compared to industry)
• Attrition rate higher in the longer term, once the “low hangingR&D fruits” have been picked
• R&D costs lower, but failure rates may be higher due toinadequate funding
CIPIH 3.3: “[…] governments cannot passively rely on what these partnerships clould eventually deliver; there is a need for stronger commitment on their partfor an articulatedarticulated and and sustainablesustainable efforteffort toto addressaddressthe the researchresearch gapsgaps””
PDPs’ new R&D business model:a transformational force or a
non-threatening niche?
DNDi’s innovative partnership with Sanofi-
Aventis on the production of antimalarials
2002• “WHO recommends in particular the use of drug
combinations containing Artemisinin”– Artesunate-SP– Artemether-lumefantrine– Artesunate-amodiaquine (AS-AQ)– Artesunate-mefloquine (AS-MQ)
• For both AS-AQ and AS-MQ– No co-formulations– No partners
Malaria: Rationale for the Fixed-Dose ACT Project
DNDi’s FACT Project
Objectives• 2 fixed-dose ACTs– Easy to use: • fewer tablets in regimen•paediatric strengths•ensure drugs are taken
together and in correct proportions
– Affordable– Available as public good
AS/MQ (Farmanguinhos)
AS/AQ (s-a)
AS/AQ: DNDi and sanofi-aventisAn Innovative Partnership
• DNDi licensed the product to s-a in Dec 2004
• Public price « at cost »– target <US$1 for adult, US$0.50 for
children• Patent free arrangement• Pediatric formulations available• Drug registered in Morocco• Production in Morocco good

ASAQ: governments’ reactions• Germany “I am particularly pleased of course that the new drug will be
available without any patents for all suppliers and patients, i.e. as a public good. By taking this route, all those involved are making an importantstatement about affordable medical care for the people in developingcountries” [Minister Heidemarie Wieczorek-Zuel]
• Italy “ We do welcome the public good approach that has inspired the partnership between DNDi and Sanofi- Aventis….which has produced open and shared innovation. This is the way to follow” [State Secretary Patrizia Sentinelli]
• UK “ The development of ASAQ is not only a wonderful breakthroughwhich will allow poor people to access effective treatment for malaria. The beauty of ASAQ is its simplicity and the fact that it will be non-patented. This means that developing country governments and patientsare much more able to afford it and I am confident that the lives of millions of people will be improved as a result of this successful and innovative partnership. " [Gareth Thomas, UK Minister for InternationalDevelopment]
ASAQ: more reactionsEuropean Parliament “I very much welcome the fact that the new ASAQ
antimalarial fixed-dose combination is born without patent. This means that, for the first time, the health of millions of people has been rated more important than profits in the creation of a new life-saving drug.
I therefore would like to offer my deepest congratulations to DNDi and Sanofi/Aventis, as you finally give us the tangible evidence that patents can be skipped in the interest of public health, especially for poor people with no purchasing power. As you know, this is a concern that all human rights organizations and the civil society worldwide have voiced for years, claiming the fundamental people’s right of access to essential health tools.
Thanks to ASAQ solution, it will be more difficult now for the big pharmaceutical companies to defend the thesis according to which it is not possible to make progress in pharmaceutical innovation, without the patent profit mechanism” [MEP Luisa Morgantini, vice-president of the EP, delegated for Africa]
Which direction do we want totake ?
IGWG provides a historic opportunity toincrease appropriation about the requirements linked to essential healthR&D, and to project WHO/ governmentcommitments globally, well beyond the mid-term framework defined by WHA 59.24.
