River blindness
Developing a rapid cure for millions at risk of blindness
With a portfolio of four R&D projects, we are advancing the development of new drug candidates to develop a safe, effective, field-adapted treatment for river blindness.
Filarial diseases, including river blindness and lymphatic filariasis, are a debilitating group of diseases caused by parasitic worms transmitted by the bite of blood-feeding insects. People are infected with river blindness (also known as onchocerciasis) by repeated exposure to blackflies that breed in fast-flowing rivers. The flies transmit worms that can cause severe itching, disfiguring skin conditions, and irreversible blindness. Millions of people in sub-Saharan Africa are at risk.
Current approaches to eliminating river blindness rely on mass administration of the drug ivermectin. These campaigns need to be repeated for 10 to 12 years as the drug only kills juvenile worms – not adult worms that can live for more than 10 years in the human body. Ivermectin is not safe for people who also live with Loa Loa (African eye worm) and women who are pregnant – leaving millions at risk.
Treatments that can kill adult worms, are field-adapted, and safe for all people who need them are urgently needed.
‘When the darkness came over me, not even my glasses were any use to see. I felt desperate, abandoned by society.’
Professor Alfonse, a former teacher, fled conflict in the city to live in the greener pastures of Makana. While tending to his fields, he was bitten by blackflies that transmit river blindness. He dreams for more research and innovation for this neglected disease.
What we have achieved
We have built a portfolio of four R&D projects for river blindness and are pursuing the clinical development of two new drug candidates.
What we are doing for people with river blindness
We aim to complete development and register at least one new drug for river blindness. We are advancing the clinical development of two compounds with promising action against the parasite Onchocerca volvulus, and the pre-clinical development of one additional compound. Together with the IVM-KIDS consortium, we are also supporting the development of a new paediatric formulation of ivermectin suitable for young children.
New effective, field-adapted drug. Together with Bayer Pharma, we are working to develop emodepside as a new treatment for river blindness with the potential to kill both adult filarial worms and their embryonic larvae, which can cause debilitating and disfiguring clinical symptoms.
Based on encouraging pre-clinical data, DNDi and our partners in the HELP Consortium are moving forward with the pharmaceutical development of oxfendazole, identified in 2016 as a potential treatment for river blindness capable of eliminating adult worms.
Ivermectin is a critical drug in use against parasitic worm diseases such as lymphatic filariasis – but children have long been excluded from receiving the treatment due to lack of data and lack of a suitable paediatric formulation. We are working with partners across Europe and sub-Saharan Africa to develop and test a safe, child-friendly, field-adapted formulation of ivermectin.
