Abstract
Recent clinical trials investigating treatment of chronic indeterminate Chagas disease with two re-purposed azole anti-fungal drugs, posaconazole and ravuconazole, revealed their inferiority to the current standard-of-care benznidazole and highlighted the inadequacy of the existing pre-clinical testing paradigm for this disease. A very limited number of controlled clinical trials for Chagas disease have been conducted to date. The selection of these compounds for clinical evaluation relied heavily on pre-clinical data obtained from in vitro screens and animal studies. This chapter reviews the evolution of CYP51 as a target for Trypanosoma cruzi growth inhibition and also explores the impact of clinical trial data on contemporary Chagas disease drug discovery. Advances in pre-clinical profiling assays, the current compound landscape and progress towards the identification of new drug targets to re-invigorate research are reviewed.
