Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The objective of the study is to assess the efficacy and safety of artemether+lumefantrine (20 mg/120 mg in each table) twice daily doses for three days for the treatment of uncomplicated falciparum (Afgoye site) and vivax (Bosaso site) malaria. The dose regimens for both Plasmodium and vivax infection 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.

All treatments will be taken orally under direct supervision by the health worker and will be followed up for 28 days.

Outcomes
Primary outcome [1] 306769 0
Percent of treatment failures (early treatment failure + late clinical failure +late parasitological failure). This is composite primary outcome.
Study patients will be evaluated for parasitological and clinical responses during the 28 days follow-up and treatment outcomes will be classified according to the latest WHO protocol.
Timepoint [1] 306769 0
Days 0, 1, 2, 3, 7, 14, 21, 28
Primary outcome [2] 306770 0
Percent of adverse event following treatment of artemether+lumefantrine 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.

Patients or care takers of 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 areas 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 in the study.

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 Subjects will be considered withdrawn from the analysis if the PCR results are unclassifiable or if the results of PCR indicate that the failure is due to reinfection with other species.The final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.

Summary
Brief summary
Title: Efficacy and safety of artemether+lumefantrine for the treatment of uncomplicated Plasmodium falciparum in Afgoye site and Plasmodium vivax in Bosaso site, Somalia
Purpose: To assess the efficacy of current first-line treatment.
Objective: To assess the efficacy and safety of artemether+lumefantrine for the treatment of uncomplicated P. falciparum and P. vivax, Somalia.
Study Sites: Afgoye for P. falciparum and Bosaso for P. vivax.
Study Period: From July 2018 to April 2019
Study Design: One arm prospective study.
Patient population: Febrile patients aged between 6 months and 60 years, inclusive, with confirmed uncomplicated P. falciparum or P. vivax infection. Female minors aged 12-17 years and unmarried females aged 18 years and above will be excluded as subjecting them to pregnancy testing is unacceptable according to the local customs and cultures.
Sample Size: A total of 88 patients will be enrolled in each site.
Treatment(s) and follow-up: Artemether+lumefantrine twice daily for 3 days will be evaluated. Clinical and parasitological parameters will be monitored over a 28-day follow-up period to evaluate drug efficacy.
Primary endpoints: The proportion of patients with early treatment failure, late clinical failure, late parasitological failure or an adequate clinical and parasitological response as indicators of efficacy. Recrudescence will be distinguished from re-infection by polymerase chain reaction (PCR) analysis.
Secondary endpoints:
• The frequency and nature of adverse events
• proportion of polymorphism of molecular markers for artemisinin resistance (K13)
