Filaria: 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.

Filarial diseases 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 and disfiguring skin lesions, and repeated infection can lead to blindness. Millions of people in sub-Saharan Africa are at risk.

Treatments that can kill adult filarial worms and be used for individual patient treatment are urgently needed. The current approach to eliminating river blindness is based on the mass distribution of ivermectin. While successful in reducing the prevalence of the disease, these programmes need to be repeated for 10-12 years because the drug only kills juvenile worms – not the adult worms, which can live for more than ten years in the human body.

What we have achieved

We have built a portfolio of four R&D projects for river blindness and are pursuing the pre-clinical development of 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 also seeking to identify potential new drug candidates by evaluating registered drugs, as well as pre-clinical and clinical drug candidates to populate the empty drug pipeline.

Translational research

Emodepside

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.

Translational research

Tylamac (ABBV-4083)

Targeting Wolbachia bacteria to kill worms. The worms that cause river blindness are dependent on Wolbachia bacteria for growth, development, reproduction, and survival. We are developing a potential treatment to eliminate the bacteria and, in turn, kill the filarial worms that cause river blindness.
