Biodistribution & persistence
Crosses the blood-brain barrier; brain levels about 0.6x plasma in rats
“Fexinidazole penetrated the blood brain barrier with a brain Tmax of between 2 and 8 hours after dosing in rats. The level of fexinidazole in brain was approximately 0.6 times the levels in plasma.”

Modality-specific risk
QT prolongation from the fexinidazole sulfone metabolite
“Fexinidazole sulfone levels at clinical exposures could therefore contribute to the Qt prolongation described in patients in Section 5.2 of the Fexinidazole Prescribing information.”
