Study type
Interventional
Description of intervention(s) / exposure
The study aims to evaluate the efficacy and safety of artemether-lumefantrine (20 mg/120 mg in each table) twice daily doses for three days in one site and dihydroartemisinin-piperaquine (40mg/320 mg) once daily for three days in three sites for the treatment of uncomplicated falciparum. For artemether-lumefantrine, the dose regimens will be calculated based on 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. For dihydroartemisinin-piperaquine, 4mg/kg body weight (bw) dihydroartemisinin+18mg/kg bw piperaquine will be given. All treatments will be taken orally under direct supervision by the health worker. The patients treated with artemether-lumefantrine will be followedup for 28 days and those treated with dihydroartemisinin-piperaquine will be followe-up for 42 days.

Outcomes
Primary outcome [1] 307701 0
Percent of treatment failures (early treatment failure + late clinical failure + late parasitological failure). This is composite primary outcome.

Study patients will be assessed for parasitological and clinical responses during the 28 days (artemether-lumefantrine) or 42 days (dihydroartemisinin-piperaquine) follow-up and treatment outcomes will be classified according to the latest WHO protocol.
Timepoint [1] 307701 0
Days 0, 1, 2, 3, 7, 14, 21 and 28 for artemether-lumefantrine
Days 0, 1, 2, 3, 7, 14, 21, 28,35 and 42 for dihydroartemisinin-piperaquine
Primary outcome [2] 307702 0
Percent of adverse event following treatment of artemether-lumefantrine or dihydroartesmisinin-piperaquine will be investigated.
The 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. Those for dihydroartemisinin include asthenia, cough, diarrhoea, fever, loss of appetite, nausea, vomiting.

Patients or care takers of children will be asked on each visit about previous symptoms that have emerged since the previous follow-up visit. When clinically indicated, patients will be assessed and treated appropriately. All adverse events will be recorded on the case report form.
Timepoint [2] 307702 0
Days 0, 1, 2, 3, 7, 14, 21 and 28 artemether-lumefantrine
Days 0, 1, 2, 3, 7, 14, 21, 28, 35 and 42 artemether-lumefantrine
Secondary outcome [1] 352583 0
Prevalence of mutations in k13 gene associated with artemisinin resistance.

Parasite DNA extracted from dried blood spots will be analyzed by PCR and sequenced for the presence of mutations in k13 gene (molecular marker for artemisinin resistance)
Timepoint [1] 352583 0
Day 0 (before treatment is given)
Secondary outcome [2] 352584 0
Prevalence of amplification in plasmepsin 2 gene associated with piperaquine.

Parasite DNA extracted from dried blood spots will be analyzed by PCR for variatios of plamsepsin2 copy number (molecular marker for piperaquine resistance)

Day 0 (at recruitment) samples

Sample size estimation
Treatment failure rate to artemether-lumefantrine and dihydroartemisinin-piperaquine in the study areas is assumed as 5%. At a confidence level of 95% and a precision around the estimate of 5%, a minimum of 73 patients will be included per drug. With a 20% increase to allow loss to follow-up and withdrawals during the 28-day (artemether-lumefantrine) or 42-day (dihydroartemisinin-piperaquine) follow-up period, 88 patients per site will be included in the study. A total sample of 352 patients is targeted.

Analysis of data
The WHO excel software programs will be used for data management and analysis. Data will be analyzed by two methods: the Kaplan-Meier method and per-protocol analysis. Subjects will be considered withdrawn from the analysis if the PCR results are unclassifiable or if the results of PCR indicate that the failure is due to reinfection with other species. The final analysis will include:

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 28, 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.
