Nifurtimox-eflornithine combination therapy (NECT) Sleeping sickness
Better, simpler, shorter treatment for sleeping sickness patients and health staff
The first improved treatment for sleeping sickness
Before 2009, the best treatment for sleeping sickness, eflornithine, was extremely complex to distribute and administer in regions affected by the disease. All-too-often, doctors would have no choice but to use melarsoprol, a highly toxic, arsenic-based drug that killed 1 in 20 patients.
In 2009, results from DNDi clinical trials showed that a simpler and shorter nifurtimox-eflornithine combination therapy (NECT) was safe and effective to treat sleeping sickness. NECT has significant practical benefits in comparison to eflornithine: there are fewer intravenous infusions (14 instead of 56), treatment length is shorter, and it is more cost effective. As a result, NECT treatment is not only better for patients, it also simplifies the logistics and staffing needed at treatment centres, which are often in remote areas.
- Recommended as first-line treatment in all 13 endemic countries, all of which receive free supplies from WHO via drug donations by Sanofi and Bayer
- 100% of stage-2 gambiense sleeping sickness patients treated with NECT in endemic African countries
- Added to the WHO Essential Medicines List in 2009, and the WHO Essential Medicines List for Children in 2013.
- Developed in partnership between DNDi, Médecins Sans Frontières, Epicentre, the HAT Platform, Swiss Tropical & Public Health Institute, national control programmes of the Democratic Republic of the Congo and Republic of Congo, with support of the World Health Organization and drugs donated by Sanofi and Bayer
“It was 2007 when I began to feel tired and weak. I’d sleep during the day but not at night. I was so weak. I received malaria treatment in 2008, but it didn’t work. I tried traditional medicines, but it didn’t work either. Finally, in 2012 a mobile team came to the village, and we found out I had sleeping sickness. I went to the hospital and received NECT. I’m cured and feel fine now.”
