- Target disease: Filarial diseases
- Main partners (since project start): Bonn University Hospital, Institute of Medical Microbiology, Immunology and Parasitology, Germany; Northwick Park Institute for Medical Research, UK; University Hospitals of Geneva; Switzerland.
- Funding: Bill & Melinda Gates Foundation, USA; Médecins Sans Frontières/Doctors without Borders, Department for International Development (DFID), UK.
Following a drug repurposing strategy, screening of compounds against Onchocerca guttura and Onchocerca lienalis identified several candidates from compound libraries provided by pharmaceutical companies. These compound collections are well-characterized chemical series which have been extensively optimized for use in other indications. Although the project was quite successful, none of the identified candidates had a drug profile with utility for filarial diseases. Screening of several more companies yielded further candidates. With funding from the Bill & Melinda Gates Foundation, these companies are conducting a hit-to-lead and lead optimization programme, which aims to develop a drug candidate for filarial indications. DNDi has contributed to this effort by providing biological resources, expertise, and the target product profile to select the best candidates.
Completion of screening identified several hits and leads. One successful compound is a well-known antihelminthic (oxfendazole) that is currently being investigated for feasibility of use in humans.These efforts will continue throughout 2018.
In conjunction with industrial partners, Abbvie and Celgene, further lead optimization was carried out. These efforts will continue throughout 2017, with the aim of delivering a pre-clinical candidate for filarial diseases.
