Drugs for Neglected Diseases Initiative
The Drugs for Neglected Diseases Initiative (DNDi) is a collaborative, patients’ needs-driven, non-profit drug research and development (R&D) organization that is developing new treatments for neglected diseases, notably leishmaniasis, sleeping sickness (human African trypanosomiasis, HAT), Chagas disease, malaria, paediatric HIV, and specific helminth infections.
Acting in the public interest and to respond to patients’ needs, DNDi bridges the existing R&D gaps in essential drugs for these diseases by leading drug R&D projects in collaboration with the international research community, the public sector, the pharmaceutical industry, and other relevant partners. The initiative’s primary objective is to deliver 11 to 13 new treatments by 2018 for these diseases and to establish a strong R&D portfolio. In doing so, DNDi is also working to use and strengthen existing capacities in disease-endemic countries, and advocate for the need to develop new treatments for the most neglected diseases. To date, DNDi has built the largest ever R&D portfolio for the kinetoplastid diseases (leishmaniasis, HAT, and Chagas) and has delivered 6 new treatments: 2 for malaria, 1 for HAT, 2 for visceral leishmaniasis, and 1 for Chagas disease.
Led by its Executive Director Bernard Pécoul, DNDi’s headquarters are in Geneva, Switzerland, with offices in Kenya, India, Brazil, Malaysia, Japan, the Democratic Republic of Congo, and an affiliate in the USA.
Despite major advances in drug development in recent decades, essential medicines to treat many diseases that affect the world’s poor are either too expensive, no longer produced, highly toxic, or ineffective. Well aware of these issues from its field experience in poor and remote areas, the humanitarian organization Médecins Sans Frontières committed its 1999 Nobel Peace Prize funds to develop an alternative model for the research and development (R&D) of new drugs for neglected diseases.
As a result, in 2003, seven organizations from around the world joined forces to establish DNDi: • five public sector institutions – the Oswaldo Cruz Foundation from Brazil, the Indian Council of Medical Research, the Kenya Medical Research Institute, the Ministry of Health of Malaysia and France’s Pasteur Institute • one humanitarian organization, Médecins sans Frontières (MSF) • one international research organization, the Special Programme for Research and Training in Tropical Diseases (TDR), which acts as a permanent observer to the initiative.
DNDi won 2012 BBVA Foundation Frontiers of Knowledge Award in the Development Cooperation category for developing and delivering new, effective and affordable treatments for poverty related diseases including Chagas disease, sleeping sickness, malaria and leishmaniasis affecting the world’s most vulnerable populations.
Working in partnership with private industry, public institutions, academia and NGOs, DNDi has built the largest ever R&D portfolio for the kinetoplastid diseases and has currently underway six projects in Implementation stage, seven in the clinical, and nine in the pre-clinical.
To date, DNDi has made available 6 new treatments for neglected diseases:
- ASAQ for malaria, 2007
Launched in 2007, this antimalarial product is the fixed-dose combination of artesunate/amodiaquine (ASAQ). It is the result of an innovative partnership between DNDi and Sanofi. Produced in Marocco, this product is cheap (available at only 0.5$ for children, 1$ for adults), administered in a simple regimen (1 or 2 tablets once a day for 3 days) and meets the latest WHO guidelines for the treatment of malaria (recommendation of treating malaria with Artesunate-based Combination Therapies – ACTs). End 2011, ASAQ was registered in 30 sub-Saharan countries, in India, and in Colombia, and more than 120 million treatments had been distributed.
- ASMQ for malaria, 2008
The second antimalarian treatment developed by DNDi is a fixed-dose combination of artesunate and mefloquine launched in 2008. Developed by a collaboration between DNDi, Brazil and South-East Asia within the FACT Project Consortium, this product consists of a 2-in-1 combination ensuring that both drugs are taken together in correct proportions. It has a simple and adapted regimen, a 3 years shelf life and a very high compliance rate. ASMQ is produced in Brazil by Farmanguinhos/Fiocruz and was registered there in 2008. Thanks to a South-South technology transfer, it is now also produced by Cipla and registered in India (2011).
- NECT for sleeping sickness, 2009
NECT, a combination therapy of nifurtimox and eflornithine, is the first new, improved treatment option in 25 years for stage 2 (advanced stage) human African trypanosomiasis (HAT), also known as sleeping sickness. Result of a six-year partnership between NGOs, governments, pharmaceutical companies, and the WHO, it was launched in 2009 and included in the WHO Essential Medicines List. It is cheaper and requests shorter hospitalization than previous treatment. It is much safer than the previously widely used arsenic-based Melarsoproll that kills 5% of the patients. In 2011, it was available in 12 African countries that account for 99% of reported HAT cases.
- SSG&PM for visceral leishmaniasis, 2010
SSG&PM, a sodium stibogluconate plus paramomycin combination therapy, is a shorter-course, cost-efficient treatment option against Visceral Leishmaniasis in East Africa available since 2010. It is the result of a six-year partnership between DNDi, the Leishmaniasis East Africa Platform (LEAP), the National Control Programmes of Kenya, Sudan, Ethiopia, and Uganda, Médecins Sans Frontières (MSF) and The World Health Organization (WHO).
- Visceral leishmaniasis treatments in Asia, 2011
In 2010, a study investigating the three possible 2-drug combinations of amphotericin B (AmBisome), miltefosine and paromomycin was completed in India. All three combination treatments were shown highly efficacious (> 97.5% cure rate). A WHO Expert committee recommended these treatments to be used preferentially to current established monotherapy treatments for VL in South Asia. DNDi is working with TDR and WHO to facilitate their introduction and support VL elimination strategies.
- Paediatric benznidazole for Chagas disease, 2011
It is the only paediatric dosage treatment for Chagas disease, launched in 2011 through a collaboration between DNDi and LAFEPE (Laboratório Farmacêutico do Estado de Pernambuco). It is designed for infants and young children under 2 years of age (20 kg body weight) infected congenitally. Thanks to its age‐adapted, easy‐to‐use, affordable, and non‐patented tablet, the new treatment contributes to improved dosing accuracy, safety, and adherence to treatment. Paediatric benznidazole was granted registration by Brazil’s National Health Surveillance Agency (ANVISA), with further endemic countries targeted for obtaining registration.
Disease-specific regional platforms
DNDi works closely with partners in disease-endemic countries to strengthen existing clinical research capacity as well as to build new capacity where necessary. DNDi helped in setting up and works with 3 regional disease-specific platforms in Africa and Latin America:
• The Leishmaniasis East Africa Platform (LEAP) on leishmaniasis
• The HAT Platform on sleeping sickness, or human African trypanosomiasis
• The Chagas Clinical Research Platform (CCRP) on Chagas disease
Their mission is to define patients needs, taking into consideration the local conditions, bring together key regional actors in the field of health, reinforce clinical capacities in endemic regions, address infrastructural requirements where necessary and provide on-site trainings. These platforms contribute to increase the chances of registration, uptake, and sustainable access of new treatments.
