Trial of Artemether-Lumefantrine Alone and in Combination With Ivermectin to Reduce Post-Treatment Malaria Transmission (ACTIVE)

A Double Blind Randomized Controlled Trial of Artemether-Lumefantrine Alone and in Combination With Ivermectin to Reduce Post-Treatment Malaria Transmission

The purpose of this study is to determine the safety and impact of ivermectin, administered as single or repeated dose, in combination with artemether-lumefantrine in reducing the proportion of mosquitoes that survive and become infected after feeding on a blood meal from a malaria-infected individual.

  • malaria parasite density ≥ 10,000 parasites/µL
  • clinical symptoms indicating severe malaria
  • axillary temperature ≥ 37.5°C
  • Body Mass Index (BMI) below 18 or above 32 kg/m2

  • known disturbances of electrolyte balance, e.g. hypokalaemia or hypomagnesaemia.
  • taking drugs which may be metabolized by cytochrome enzyme CYP2D6 (e.g., flecainide, metoprolol, imipramine, amitriptyline, clomipramine).
