A Phase II PoC study of fexinidazole was initiated in 2014 in Cochabamba and Tarija, Bolivia. A total of 47 patients were included, but the study was interrupted due to safety and tolerability issues. Interim data efficacy and safety analysis suggested high efficacy rates of fexinidazole and a decision was made to extend clinical study follow-up to 12 months. Analysis of key efficacy outcomes and safety, demonstrated high efficacy findings at the lowest dose tested and for all treatment durations, with safety concerns around treatment with high doses tested for more than 14 days. In addition, acceptable safety and tolerability was found at low doses and short treatment durations – taken together, these results warrant further investigation of fexinidazole for Chagas disease.
