Patient-friendly medicine for sleeping sickness

What it is

Fexinidazole is the first all-oral treatment for sleeping sickness. Taken as simple pills over 10 days, it eliminates the need for hospitalisation and painful lumbar punctures, and has become the most widely used therapy for this disease.

Why it matters

Although sleeping sickness is nearing eradication, it persists in the poorest and most remote areas of Africa, where delivering care is a significant challenge. The disease is usually fatal without treatment, making this patient-friendly innovation essential.

The story

Human African trypanosomiasis, or sleeping sickness, is a deadly parasitic disease transmitted by tsetse flies. Although nearing eradication, the disease remains endemic in 36 African countries, placing millions of people at risk. Existing treatments have been complex, toxic, and painful.[1]

EDCTP has supported the HAT-r-ACC consortium,[2] enabling the development of Fexinidazole Winthrop, the first all-oral treatment for T.b. rhodesiense sleeping sickness[3]. This innovative medicine received a positive opinion from the European Medicines Agency in 2023, prompting WHO to update its guideline to recommend fexinidazole for the treatment of HAT caused by T.b. rhodesiense. In 2024, fexinidazole was registered for treating T.b. rhodesiense sleeping sickness by the Democratic Republic of the Congo and approval for its use was granted by Malawi.

Developed by DNDi, Sanofi, and partners,[4]Fexinidazole represents a major advance in the treatment of sleeping sickness, including severe cases, with a simple 10-day, exclusively oral regimen. Today, it accounts for approximately 70% of all sleeping sickness treatments, bringing the continent closer to eradication and offering a simpler, safer, and more effective therapy for affected populations. Global Health EDCTP3 continues to support research and innovation for enhanced interventions against sleeping sickness[5] to advance towards its eradication by 2030.
