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) and artemether+lumefantrine (20 mg artemether and 120 mg lumefantrine in a tablet) for the treatment of uncomplicated P. falciparum infection. The doses of artemether+lumefantrine is based on weight bands: one tablet to those weighing 5-14kg; two tablets for 15-24 kg; three tablets for 25-34 kg and four tablets for greater than or equal to 35 kg; once daily for 3 consecutive days.. The treatment will be taken orally under direct supervision by the health worker. These two artemisinin-based combinations will be tested separately. The patient will be given either artesunate+amodiaquine or artemether+lumefantrine. Artesunate+amodaiquine will tested in all sites while artemether+lumefantrine will evaluated in two sites. Eligible subjects will be treated for three days and followed up for 28 days.
Intervention code [1] 295349 0
Treatment: Drugs
Comparator / control treatment
Not applicable.
This is a two arm cohort prospective study for each drug (in each site patients will be enrolled for artesunate+amodiquine until the target sample size is reached and then patients will be enrolled into artemether-lumefantrine) study.
Control group
Uncontrolled

Outcomes
Primary outcome [1] 298997 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) and clinical responses during the 28 days follow-up and treatment outcomes will be classified according to the latest WHO protocol.
Timepoint [1] 298997 0
At day 28 following initiation of treatments
Secondary outcome [1] 325842 0
Percent of adverse event will be documented.
The known adverse events of:
a. artesunate+amodiaquine are abdominal pain, asthenia, cough, diarrhoea, dizziness, insomnia, loss of appetite, nausea, vomiting.

b. artemether+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 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] 325842 0
At day 28 following initiation of treatments
Secondary outcome [2] 325843 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] 325843 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 and 120 months with uncomplicated malaria who meet the study inclusion criteria will be enrolled, treated on site with 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.

Patients will be enrolled sequentially to the two drugs: in each site patients will be enrolled for artesunate+amodiaquine until the sample size is reached and then patients will be enrolled into artemether-lumefantrine.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Not applicable.
This is a two-arm cohorts sequential prospective (in each site patients will be enrolled for artesunate+amodiaquine until the sample size is reached and then patients will be enrolled into artemether-lumefantrine) evaluation of clinical and parasitological responses to directly observed treatment.

Intervention assignment
Other
Other design features
Where the two drugs will be studied, sequential:recruitment will be used: eligible patients will be enrolled in the artesunate+amodiaquine first and when the target sample is reached, the subsequent patients will be enrolled in the artemether+lumefantrine group
Phase
Phase 4
Type of endpoint/s
Safety/efficacy
Statistical methods / analysis
As the treatment failure rate to artesunate+amodiaquine or artemether-lumefantrine. in the area is estimated to 5%. At a confidence level of 95% and a precision around the estimate of 5%, a minimum of 73 patients will be included. With a 20% increase to allow loss to follow-up and withdrawals during the 28-day follow-up period, 88 patients per site will be included for each drug and per site. A total of 528 patients [352 (88 x 4 sites)] for artesunate+amodiaquine group and 176 [(88 x 2 sites)] for artemether-lumefantrine will be enrolled.
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.
