English English Français Fexinidazole would be first all-oral treatment* under investigation for both first and second stages of sleeping sickness, a fatal disease, endemic in Africa Sanofi submission is the culmination of 10 years of collaboration with the Drugs for Neglected Diseases initiative (DNDi) in research and development Dossier will be reviewed under the Article 58 procedure, which is intended for medicines that will be used outside of the European Union Sanofi has asked the European Medicines Agency (EMA) to review fexinidazole for the treatment of sleeping sickness. Fexinidazole is being developed in collaboration with the Drugs for Neglected Disease initiative (DNDi). It would be the first all-oral treatment under investigation for Trypanosoma brucei gambiense human African trypanosomiasis (g-HAT), commonly known as sleeping sickness. This treatment is expected to contribute to the elimination of the disease. EMA has accepted the application under a special procedure called “Article 58” which allows the EMA to give a scientific opinion, in co-operation with World Health Organization (WHO), for the evaluation of medicinal products that are intended exclusively for markets outside of the European Union. Fexinidazole was previously granted accelerated assessment by the EMA. “The acceptance by the EMA of the fexinidazole regulatory dossier is a critical step in the registration process,” said Dr. Nathalie Strub-Wourgaft, DNDi Medical Director. “Results of the Phase II/III clinical trials conducted with our partners in Democratic Republic of Congo and the Central African Republic, which were published in The Lancet** last November, showed the product to be effective and well tolerated.” Following the evaluation of the dossier, the EMA will publish its scientific opinion of the benefit risk of the treatment and facilitate the registration of fexinidazole in HAT-endemic countries. “This milestone is the result of an innovative collaboration between Sanofi and DNDi to address the burden of sleeping sickness,” said Dr. Ameet Nathwani, Chief Medical Officer, Sanofi. “Fexinidazole is being developed with the goal of addressing all stages of sleeping sickness and simplifying treatment by avoiding systematic hospitalization. It could represent a therapeutic breakthrough foremost for the patients and potentially support elimination efforts as per the WHO 2020 Roadmap.” * vs current standard of care oral niflurtimox and IV eflornithine ** Lancet. 2018 Jan 13;391(10116):144-154. doi: 10.1016/S0140-6736(17)32758-7. Epub 2017 Nov 4 About sleeping sickness Human African Trypanosomiasis (HAT) or “sleeping sickness” is a tropical disease affecting sub-Saharan African countries. Without prompt diagnosis and treatment, sleeping sickness is usually fatal as the parasites invade the central nervous system. Sixty million people who live mainly in rural parts of East, West and Central Africa are at risk of contracting sleeping sickness. In 2015, the total number of HAT reported cases was 2804, continuing the decreasing trend observed in recent years and in line with WHO objectives to reach the goal of elimination of the disease as a public health problem by 2020 (<2000 cases). About fexinidazole Fexinidazole is a 10 day oral treatment for HAT currently in clinical development. The treatment is being developed for all stages of sleeping sickness, meaning patients could potentially avoid systematic hospitalization and the need for lumbar puncture. In the 1970s, Hoechst (now part of Sanofi) had initiated but did not pursue pre-clinical development of fexinidazole, an antiparasitic drug. In 2005, the compound was identified by DNDi as having activity against the sleeping sickness parasite. Pre-clinical studies began in 2007. In 2009, DNDi and Sanofi concluded a collaboration agreement for the development, manufacturing, and distribution of fexinidazole, with DNDi responsible for pre-clinical, clinical, and pharmaceutical development, and Sanofi responsible for industrial development, registration, production and distribution of the drug. Phase I studies began in 2010, and the Phase II/III pivotal clinical study in 2012. DNDi’s fexinidazole programme is supported by grants from the Bill & Melinda Gates Foundation, the UK Department for International Development, the Dutch Ministry of Foreign Affairs, the German Federal Ministry of Education and Research, the German Development Agency, the French Development Agency, the French Ministry for Europe and Foreign Affairs, the Norwegian Agency for Development Cooperation, the Spanish Agency for International Development Cooperation, the Republic and Canton of Geneva, International Solidarity Service, Switzerland, the Swiss Agency for Development and Cooperation, Médecins Sans Frontières/Doctors without Borders, and other private foundations and individuals.
