Study type
Interventional
Description of intervention(s) / exposure
To assess the efficacy and safety of artesunate/amodiaquine (4 mg/kg of artesunate, 10 mg/kg of amodiaquine, 1/day for 3 days) (oral administration) for the treatment of uncomplicated P. falciparum infections in two sites in the Republic of Congo
Intervention code [1] 285589 0
Treatment: Drugs
Comparator / control treatment
To assess the efficacy and safety of artemether/lumefantrine
(20 mg of artemether and 120 mg of lumefantrine), 2/day for 3 days) (oral administration) for the treatment of uncomplicated P. falciparum infections in two sites in the Republic of Congo
Control group
Active

Outcomes
Primary outcome [1] 287882 0
Percent of treatment failures (early treatment failure + late clinical failure + late parasitological failure)

Enrolled patients will be assessed for parasitological (using microscopy), clinical responses during the 28 days follow-up and treatment outcomes will be classified according to the latest WHO protocol.
Timepoint [1] 287882 0
At day 28 following initiation of treatment
Secondary outcome [1] 298977 0
Percent of adverse event will be documented. Parents or guardians of all enrolled patients will be asked routinely about previous symptoms and about symptoms that have emerged since the previous follow-up visit. When clinically indicated, patients will be evaluated and treated appropriately. All adverse events will be recorded on the case report form.

Possible medicine related adverse effects include dizziness, itching, vomiting, abdominal pain, flatulence, headache, bodyache, diarrhoea, tinnitus and increased hair loss, macular rash, reduction in neutrophil counts and convulsions. However, it is likely that many of these effects are disease-related rather than medicine-induced.
Timepoint [1] 298977 0
At day 28 following initiation of treatment.

Treatment
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Children aged 6 months to 10 years with uncomplicated malaria who meet the study inclusion criteria will be enrolled, treated on site with either artesunate/amodiaquine or artemether/lumefantrine and monitored for 28 days. The follow-up will consist of a fixed schedule of check-up visits and corresponding clinical and laboratory examinations.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
N/A This surveillance study is 2 x one-arm prospective evaluation of clinical and parasitological responses to directly observed treatment for uncomplicated malaria with either artesunate/amodiaquine or artemether/lumefantrine.
