Summary: The in vitro metabolism and in vivo pharmacokinetic properties of DNDI-VL-2098, a potential oral agent for Visceral Leishmaniasis (VL) were studied and used to predict its human pharmacokinetics. DNDI-VL-2098 showed a low solubility, was highly permeable, and stable in vitro with very slow, if any, metabolism of the compound in vivo. It showed satisfactory PK properties in animal models with a low blood clearance and a volume of distribution of about 3 times total body water, acceptable half-life and good oral bioavailability. Allometric scaling of the preclinical PK data to human gave a blood half-life of approximately 20 h suggesting that the compound could be a once-a-day drug. The minimum efficacious dose predicted for a 50 kg human was predicted as 150 mg and 300 mg, using efficacy results in the mouse and hamster, respectively.
