Fexinidazole is an antiparasitic agent.[1] It has activity against Trypanosoma cruzi, Tritrichomonas foetus, Trichomonas vaginalis, Entamoeba histolytica,[1] Trypanosoma brucei,[2] and Leishmania donovani.[3] The biologically relevant active metabolites in vivo are the sulfoxide and sulfone.[3][4]

Fexinidazole was discovered by the German pharmaceutical company Hoechst AG, but its development as a pharmaceutical was halted in the 1980s.[5] Fexinidazole is now being studied through a collaboration between Sanofi and the Drugs for Neglected Diseases Initiative for the treatment of Chagas disease and human African trypanosomiasis (sleeping sickness).[6][7] Fexinidazole is the first drug candidate for the treatment of advanced-stage sleeping sickness in thirty years.[8]
