Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
To assess the efficacy and safety of artesunate+amodiaquine
(artesunate 4 mg/kg body weight + amodiaquine 10mg/kg body weight once daily for 3 consecutive days) for the treatment of uncomplicated P. falciparum infection. The treatment will be taken orally under direct supervision by the health worker. Eligibile subjects will be treated for three days and followed up for 28 days.
Intervention code [1] 292471 0
Treatment: Drugs
Comparator / control treatment
Not applicable.

This is a surveillance study of one-arm.
Control group
Uncontrolled

Outcomes
Primary outcome [1] 295714 0
Percent of treatment failures (early treatment failure + late clinical failure +late parasitological failure). This is composite primary outcome.

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] 295714 0
At day 28 following initiation of artesunate+amodiaquine
Secondary outcome [1] 316293 0
Percent of adverse event will be documented. The known adverse events of artesunate+amodiaquineare Asthenia, cough, diarrhoea, fever, loss of appetite, nausea, vomiting.

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.
Timepoint [1] 316293 0
At day 28 following initiation of treatment.
Secondary outcome [2] 316294 0
Prevalence of artemisinin resistance molecular markers (K13).

Parasite DNA extracted from the dried blood spots will be analyzed by PCR and sequencing for the presence of K13 (molecular marker for artemisinin resistance).
Timepoint [2] 316294 0
At Day 0 (prior initiation of treatment)

Treatment
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients aged between 6 month and 5 years with uncomplicated malaria who meet the study inclusion criteria will be enrolled, treated on site with artesunate+amodiaquine 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)
Not applicable.

This surveillance study is a one-arm prospective evaluation of clinical and parasitological responses to directly observed treatment for uncomplicated malaria with artesunate+amodiaquine.

Safety/efficacy
Statistical methods / analysis
Currently the treatment failure rate to
artesunate+amodiaquine in the study area is assumed unknown and assumed to be <50%. At a confidence level of 95% and a precision around the estimate of 10%, a minimum of 96 patients must be included per drug test. With a 20% increase to allow loss to follow-up and withdrawals during the 28-day follow-up period, 103 patients should be included in the study.

Excel WHO tailored database will be used for data management and analysis. Data will be analysed by two methods: the Kaplan-Meier method and per-protocol analysis.
