Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
To assess the efficacy and safety of (i)artesunate+sulfadoxine/pyrimethamine (standard dose of artesunate 4 mg/kg bw for three days plus a single dose of 25/1.25 mg/kg bw of sulfadoxine/pyrimethamine in the first day ) and (ii) artemether/lumefantrine (20 mg of artemether and 120 mg of lumefantrine in a tablet with dose regimen of: one tablet to those weighing 5-14kg; two tablets for 15-24 kg; three tablets for 25-34 kg and four tablets for greater or equal to 35 kg) for the treatment of uncomplicated P. falciparum infection. The treatment will be taken orally under health worker's supervision. Eligibile subjects will be treated for three days (daily dose for artesunate+sulfadoxine/pyrimethamine and twice daily dose for artemether lumefantrine) and followed up for 28 days.
Intervention code [1] 290757 0
Treatment: Drugs
Comparator / control treatment
It is not a comparative study. Patients will be enrolled first in the artesunate+sulfadoxine/pyrimethamine study and when the required sample size is reached, the subsequent patients will be enrolled in the artemether/lumefantrine arm. This will be a sequential enrolment.
Control group
Uncontrolled

Outcomes
Primary outcome [1] 293758 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] 293758 0
At day 28 following initiation of treatment
Secondary outcome [1] 311768 0
Percent of adverse event will be documented.

Patients or parents/guardians of 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.

The known adverse reactions are abdominal discomfort, nausea, headache and dizziness
Timepoint [1] 311768 0
At day 28 following initiation of treatment.
Secondary outcome [2] 312340 0
Prevalence of sulfadoxine/pyrimethamine molecular markers (dhfr and dhps).

Dhfr and dhps genotypes will be determined using nested mutation-specific PCR and/or PCR-RFLP. Dhfr mutations at codons 51, 59 and 108 and dhps mutations at codons 437 and 540 will be analysed.
Timepoint [2] 312340 0
Day 0 (prior to the initiation of treatment)
Secondary outcome [3] 312341 0
Prevalence of artemisinin resistance (K13) molecular markers.

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).

Day 0 (prior to initiation of treatment)

Purpose of the study
Treatment
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients aged 6 months to 60 years with uncomplicated falciparum malaria who meet the study inclusion criteria will be enrolled, treated on site with either artesunate+sulfadoxine/pyrimethamine 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 is surveillance study of 2 x one-arm prospective evaluation of clinical and parasitological responses to directly observed treatment for uncomplicated falciparum malaria with either artesunate+sulfadoxine/pyrimethamine or artemether+lumefantrine.

Intervention assignment
Other
Other design features
Patients will be enrolled first in the artesunate+sulfadoxine/pyrimethamine study and when the sample size of 88 is reached, the subsequent patients will be enrolled in the artemether+lumefantrine arm. This will be a sequential enrolment.

Not Applicable
Type of endpoint/s
Safety/efficacy
Statistical methods / analysis
As the treatment failure rate to artesunate+sulfadoxine/pyrimethamine and artemether+lumefantrine in the study area is 5%. At a confidence level of 95% and a precision around the estimate of 5%, a minimum of 73 patients will be included for each drug. With a 20% increase to allow loss to follow-up and withdrawals during the 28-day follow-up period, 88 patients will be included in the study per treatment.

The WHO excel software programs will be used for data management and analysis. Data will be analysed by two methods: the Kaplan-Meier method and per-protocol analysis.
