Summary

The purpose of this study is to determine the impact of varying doses of artesunate on treatment outcome and whether higher doses of artesunate can overcome the problem of compromised artemisinin sensitivity in the region. To determine the safety and tolerability of this previously untested experimental high dose (6 mg/Kg/D X 7 day, total 42 mg/Kg) artesunate monotherapy regimen.

Detailed description

A total of 150 volunteers with acute uncomplicated falciparum malaria will be randomly assigned one of 3 arms to be treated with artesunate monotherapy for 7 days at a ratio of 2:1:2. Arm 2 serves as a control and will serve as a bridge to the ARC 1 study performed in 2006/2007. Patients in Arm 1 will receive a relatively low "standard" dose, and patients in Arm 2 will receive the intermediate dose of 4 mg/kg that was used in the ARC1 study. Patients in Arm 3 will receive an experimental "high-dose" regimen. Currently available safety data extends to subjects who have received the 28 mg/Kg total dose over 7 days and to another study administering 8 mg/Kg/day for 3 days (total dose 24 mg/Kg). Subjects randomized into this study's 'high-dose' Arm 3 will, therefore, receive a total dose that is higher than has been previously studied in humans. The study design will be based on the WHO recommendations for the 'Assessment and Monitoring of Antimalarial Drug Efficacy for the Treatment of Uncomplicated Falciparum Malaria' (WHO, 2003).
