- Target disease: VL
- Main partners (since project start): Laboratory of Microbiology, Parasitology and Hygiene, University of Antwerp, Belgium; London School of Hygiene & Tropical Medicine, UK; Pfizer, UK; Sandexis, UK; Takeda Pharmaceutical Company Ltd, Japan; WuXi AppTech, China.
- Project start: February 2012
- Funding (since project start): Department for International Development (DFID), UK; Global Health Innovative Technology (GHIT) Fund, Japan.
The aminopyrazole class of compounds originally from Pfizer has shown promising early profiles for the treatment of both VL and CL. Profiling of current and new leads in a panel of drug-sensitive and drug-resistant strains of Leishmania, exploration of the in vivo dose response, pharmacokinetics, and initial in vitro safety assays are all underway. The ongoing lead optimization programme in collaboration with Takeda and supported by the GHIT Fund aims to select an optimized lead.
Additional studies, including preliminary toxicology assessment, are being planned to further understand the safety profiles of these compounds and identify the best back-up to DNDI-5561.
