Scientific titleA randomised open label study to assess the safety and efficacy of dihydroartemisinin-piperaquine (Artekin™) compared with lumefantrine-artemether (Coartem®) for the treatment of uncomplicated Plasmodium falciparum malaria in Kenyan children
Study objectivesDihydroartemisinin-piperaquine is at least as efficacious as artemether-lumefantrine for the treatment of primary and the prevention of secondary infections with Plasmodium falciparum.
Ethics approval(s)Ethics approval received from:
1. Kenya Medical Research Institute, National Ethic Review Committee (Kenya) on the 26th June 2005
2. University of Oxford, Oxford Tropical Research Ethics Committee (UK) on the 6th July 2005
3. University of Heidelberg School of Medicine, Ethics Committee (Germany) on the 8th August 2005
Health condition(s) or problem(s) studiedUncomplicated Plasmodium falciparum malaria
Intervention1. Three-day, three-dose regimen of dihydroartemisinin-piperaquine (Artekin™); co-formulation: target dose of 2 mg/kg/ once per day of dihydroartemisinin and target dose of 18 mg/kg/once per day of piperaquine
2. Three-day, six-dose regimen of artemether-lumefantrine (Coartem®); co-formulation containing 20 mg of artemether and 120 mg of lumefantrine:
2.1. 5 kg to less than 15 kg: one tablet/twice per day
2.2. 15 kg to less than 25 kg: two tablets/twice per day
2.3. 25 kg to less than 35 kg: three tablets/twice per day

Patients are followed-up for 84 days.
Intervention typeDrug
PhaseNot Specified
Drug / device / biological / vaccine name(s)Dihydroartemisinin-piperaquine (Artekin™), lumefantrine-artemether (Coartem®)
Primary outcome measure(s)

1. The cure ratio of dihydroartemisinin-piperaquine is non-inferior to that of artemether-lumefantrine (non-inferiority margin = 5%)
2. The cure ratio of dihydroartemisinin-piperaquine is at least 90%

Key secondary outcome measure(s)

1. Polymerase chain reaction (PCR)-uncorrected day 28 cure ratio
2. Safety profiles of the two treatments
3. Time to asexual parasite clearance (PCT)
4. Time to fever clearance (FCT)
5. Gametocyte prevalence and density on days 7, 14, 28, 42, 63 and 84
6. Haematological recovery (Haemoglobin [Hb] changes) from day 0 to day 28, day 42, and day 84
7. Cure ratios at day 42 (PCR corrected and PCR uncorrected)
8. Cure ratios at day 63 (PCR corrected and PCR uncorrected)
9. Cure ratios at day 84 (PCR corrected and PCR uncorrected)
10. Rate of PCR-confirmed reinfections to estimate the chemoprophylactic effect of dihydroartemisinin-piperaquine
