Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
To assess the efficacy and safety of Dihydroartemisinin+Piperaquine (4 mg/kg DHA and 18 mg/kg Piperaquine once a day for 3 days) for the treatment of uncomplicated P. falciparum infection. The treatment will be given in tablets by oral. Eligible subjects will be treated for three days and followed up for 42 days. The daily doses of the study medicine will be administered under direct supervision.

Outcomes
Primary outcome [1] 297428 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 and treatment outcomes will be classified according to the latest WHO protocol.
Timepoint [1] 297428 0
Primary outcome (treatment failures) will be assessed on Days 2, 3, 7, 14, 21, 28, 35, 42 following initiation of Dihydroartemisinin+piperaquine.
Secondary outcome [1] 321011 0
Percent of adverse event will be documented.

Known adverse events of Dihydroartemisinin+Piperaquine are 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] 321011 0
Secondary outcome (adverse events) will be assessed on Days 1, 2, 3, 7, 14, 21, 28, 35, 42 following initiation of Dihydroartemisinin+piperaquine.
Secondary outcome [2] 321012 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] 321012 0
At Day 0 (prior to initiation of the 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 60 years with uncomplicated malaria who meet the study inclusion criteria will be enrolled, treated on site with Dihydroartemisinin+piperaquine and monitored for 42 days. The follow-up will consist of a fixed schedule of check-up visits and corresponding clinical and laboratory examinations.

Safety/efficacy
Statistical methods / analysis
Treatment failure rate to dihydroartemisinin+piperaquine 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 42-day follow-up period, 88 patients will be included in the study.

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. Patients who were subsequently lost to follow-up, had reinfections, or unknown PCR, will excluded from the per-protocol analysis of treatment outcomes, but included in the Kaplan-Meier analysis until the day of withdrawal from the study.

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 42, 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 42 with 95% confidence intervals, PCR-uncorrected and PCR-corrected.
