Study type
Interventional
Description of intervention(s) / exposure
This was one arm prospective study to assess the efficacy and safety of artemether-lumefantrine (containing 20 mg artemether+ 120 mg lumefantrine in each tablet) given twice daily for three days according to the recommended weight bands as follows: 1 tablet to those weighing 5 to 14 kg; 2 tablets for 15 to 24 kg; 3 tablets for 25 to 34 kg and 4 tablets for equal or greater than 35 kg. The total target dose ranges were 5-24 mg/kg bw of artemether and 29-144 mg/kg bw of lumefantrine. All treatments was given orally under direct supervision by the health worker. The patients were followed up for 28 days

Outcomes
Primary outcome [1] 331448 0
Percent of treatment failures (early treatment failure + late clinical failure+late parasitological failure). This is a composite primary outcome.

Enrolled patients was monitored for parasitological (using microscopy) and clinical responses. PCR analysis was used to differentiate recrudescence from new infection. Treatment outcomes was classified according to the latest WHO protocol.

Days 0(before treatment), 1, 2,3, 7, 14, 21, 28
(primary endpoint)
Secondary outcome [1] 410306 0
Percent of adverse event following treatment.
Known adverse events of atemether+lumefantrine are abdominal pain, asthenia, cough, diarrhoea, dizziness, fever, headache, joint and muscle pain, loss of appetite, rush, nausea, vomiting.

Parents or guardians of all enrolled children 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.

Sample size estimation
As the treatment failure rate to artemether-lumefantrine in the area is assumed 5%, 5% has been chosen. At a confidence level of 95% and a precision around the estimate of 10%, with a 20% increase to allow loss to follow-up and withdrawals during the 28-day follow-up period, 60 patients should be included in the study per site

Data analysis
WHO excel software program was used for data management and analysis. Data was analysed by two methods: the Kaplan-Meier method and per-protocol analysis. Patients was considered withdrawn from the analysis if the PCR results were unclassifiable or if the results of PCR indicate that the failure was due to reinfection with P. falciparum.
The final analysis included:
1. a description of all patients screened and the distribution of reasons for non-inclusion in the study;
2. a description of all the patients included in the study;
3. the proportion of adverse events and serious adverse events in all the patients included in the study;
4. the proportion of patients lost to follow-up or withdrawn, with 95% confidence intervals and a list of reasons for withdrawal;
5. the cumulative incidence of success and failure rates at day 282, PCR-uncorrected and PCR-corrected; and
6. the proportion of early treatment failure, late clinical failure, late parasitological failure and adequate clinical and parasitological response at day 28, with 95% confidence intervals, PCR-uncorrected and PCR-corrected.
