Description of intervention(s) / exposure
Artesunate-pyronaridine (Pyramax) as artesunate 3 mg/kg and pyronaridine base 10 mg/kg once-daily for three days or artemisinin-naphthoquine (Arco) as artemisinin 20 mg/kg and naphthoquine phosphate 8 mg/kg once-daily for three days.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Eligible children will be enrolled at participating field sites after parental informed consent has been obtained. The study is open label but randomisation will be by computer generated code contained in a sealed envelope to be opened at the time of recruitment.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by using a randomization table created by a computer software (i.e., computerised sequence generation)
Masking / blinding
Open (masking not used)

Summary
Brief summary
We recently found that the WHO-recommended combination antimalarial therapy artemether-lumefantrine and the candidate regimen dihydroartemisinin-piperaquine were not fully effective for both falciparum and vivax malaria in young Papua New Guinean children, a group at high risk of complications and death. We plan to study two new combinations (artesunate-pyronaridine and artemisinin-naphthoquine) in the hope that at least one will prove superior and be used in treatment programs in PNG and similar countries.
