Coarsucam™ (artesunate/amodiaquine) first fixed-dose antimalarial combination to receive WHO Prequalification

Significant Step towards Expanded Global Access to Malaria Treatment
[Paris, France, and Geneva, Switzerland – October 16, 2008]

Sanofi-aventis and the non-profit Drugs for Neglected Diseases initiative (DNDi) welcome the approval, by the World Health Organization (WHO) Prequalification of Medicines Program, of Coarsucam™ / Artesunate Amodiaquine Winthrop® (“ASAQ”), the first fixed-dose combination of the two antimalarial compounds, artesunate (AS) and amodiaquine (AQ).

ASAQ is the first antimalarial, fixed-dose combination with a soluble formulation, specifically designed for children, to be granted a “prequalified” status.

The WHO Prequalification Program aims to make quality priority medicines available, primarily in the fields of HIV/AIDS, malaria and tuberculosis. Products found to live up to the WHO quality standards are included in a “prequalified list” of products. This list, initially intended for procurement of medicines by United Nations agencies, has now become a vital tool for many agencies and organizations involved in bulk purchasing of medicines.

“We are very pleased to see that the quality of the documentation generated on “ASAQ” has been recognized by the WHO Prequalification Program. The “prequalified” status makes ASAQ eligible for procurement by more countries and international agencies than before,” said Dr Robert Sebbag, Vice-President of Access to Medicines at sanofi-aventis.

“Over 200 million patients suffer from malaria, and more than one million patients, mainly children, die from this disease every year. This new status means that ASAQ will be made available to many more patients: this is a major milestone. We believe that with its very simple dosing regimen and soluble tablets specifically designed for children, ASAQ will make a difference in the field,” said Dr Bernard Pécoul, Executive Director, DNDi.

About the WHO Prequalification of Medicines Program

The WHO Prequalification of Medicines Program focuses on medicines used in the treatment of HIV/AIDS, tuberculosis and malaria and interested manufacturers of these medicines apply voluntarily to benefit from the Program. Once the products are found living up to the WHO quality standards, after inspection of manufacturing facilities that must comply with the “Good Manufacturing Practices”, and review of submitted data, they are included in list of “prequalified” products. This list was initially intended for procurement of these medicines by United Nations agencies such as UNAIDS and UNICEF. It has over the past few years become a vital tool for many agencies and organizations involved in bulk purchasing of medicines, such as The Global Fund to fight HIV/AIDS, tuberculosis and malaria, UNITAID, the President’s Malaria Initiative, etc. A “prequalified” status makes ASAQ eligible to tenders that receive funding from these agencies.

About ASAQ

Coarsucam™/Artesunate Amodiaquine Winthrop® (“ASAQ”) is the result of a partnership started in late 2004 between sanofi-aventis and DNDi to jointly develop a new fixed-dose combination of artesunate and amodiaquine. ASAQ is available under the name Artesunate-Amodiaquine Winthrop® (ASAQ) for public markets, and under the brand name Coarsucam® in private markets. ASAQ was first registered in February 2007 in Morocco, where it is manufactured, and soon thereafter in 20 sub-Saharan African countries. It was submitted to the WHO Prequalification of Medicines Program in February 2007.

ASAQ is available in 4 presentations for 4 age ranges (infants, small children, children, adolescents and adults), and each presentation is easily identified with a specific color code and pictograms to ensure appropriate usage in the field. These 4 presentations make possible a simple dosing regimen: 1 tablet per day for 3 days for infants and children, and 2 tablets once a day for 3 days for adolescents and adults. Importantly, ASAQ tablets are soluble and can be easily administered to small children, the first victims of malaria.

About DNDi
The Drugs for Neglected Diseases initiative (DNDi) is an independent, not-for-profit product development partnership working to research and develop new and improved treatments for neglected diseases such as malaria, leishmaniasis, human African trypanosomiasis, and Chagas disease. With the objective to address unmet patient needs for these diseases, DNDi was established in 2003 by Institut Pasteur and Médecins Sans Frontières along with four publicly-funded research organizations in neglected disease-endemic countries. Working in partnership with industry and academia, DNDi has the largest ever R&D portfolio for the kinetoplastid diseases and currently has 6 clinical and 4 preclinical projects. DNDi delivered its first product, a fixed-dose antimalarial “ASAQ”, in partnership with sanofi-aventis in 2007. In April 2008, DNDi delivered its second product, fixed-dose “ASMQ”, with Far-manguinhos as first-line treatment for children and adults suffering from uncomplicated P. falciparum malaria cases in Latin America and Asia.
