Description of intervention(s) / exposure
It is a single arm open label study to evaluation of the therapeutic efficacy and safety of pyronaridine-artesunate for the treatment of uncomplicated falciparum malaria. The eligible patients are treated with a daily dose of 1 tablet for 20-<24kg, 2 tablets for 24-<45 kg, 3 tablets for 45-<65kg and 4 tablets for 65 and above over 3 days. One tablet contains 60mg artesunate+18mg pyronaridine. Each dose is administered orally under the supervision of the medical doctor. A dose is repeated in full if vomiting occurs within 30 minutes of administration of the first day of administration only. The patients has a blood smear examined daily during the first week by microscopy until parasite clearance (2 consecutive negative slides on two consecutive days; both asexual and sexual stages). The patients has a weekly appointment over 42 days. If the patient do not attend for the follow-up a home-visitor from the study team will try to locate the patient and bring them to the study site.

Outcomes
Primary outcome [1] 293584 0
The proportion of adequate clinical and parasitological response (ACPR) to the antimalarial treatment. A patient receives clinical examination and parastiological test for malaria on weekly basis over 42 days when the patient does not have malaria clinical manifestation and does not have malaria parasites in the blood the treatment outcome is classified as ACPR.

Day 42
Secondary outcome [1] 311403 0
The blood samples were collected to monitor the hepatic biological values (ALT, AST, total and conjugated bilirubin and alkaline phosphatase). These values are to be obtainable on day 0, 3, 7, 14, 21, 28, 35 and 42 by a liver function test machine at each study site.

Statistical methods / analysis
- With the assumed efficacy of 90%, a sample size of 138 participants is needed for the study in three study sites for +/- 5% precision (this width is 0.1 in document), i.e., 85 to 95%. Allowing for a 5% drop out, we propose a sample size of 145 patients.

- Kaplan–Meier survival analysis
- Cox proportional hazards regression
