Plain English summary of protocol
Background and study aims
Malaria is a serious infectious disease which is common in tropical and subtropical countries. It is caused by a microscopic parasite which is spread from person to person by mosquitos. There are a lot of different drugs which are used to treat malaria, which are often used in combination with each other. The aim of this study is to compare the success of two different drug combinations (the drug combination dihydroartemisinin-piperaquine (AP), and the drug combination artemether-lumefantrine (AL) when treating malaria in young children.
Who can participate?
Children suffering from fever living within the catchment areas of the trial centres
What does the study involve?
The children involved in the study are randomly split into two groups. The first group is treated with AP and the second group is treated with AL. For the first three days after the treatment, the children’s temperature is measured to check for signs of a fever. Blood samples are taken from the children on days 1, 2, 3, 7, 14, 21, 28, 35 and 42 so the success of the drugs can be found out by looking at the levels of the parasites and how many of different types of blood cells are in the blood.
What are the possible benefits and risks of participating?
Potential benefits for participants include the good quality care that they receive from medical officers and nurses while taking part in the study. There are no direct risks of participating in the study, other than known or unknown side effects of the medications being provided.
Where is the study run from?
1. Aura Hospital (Uganda)
2. Mbarara Hosptial (Uganda)
3. Nagongera Health Centre IV (Uganda)
When is the study starting and how long is it expected to run for?
September 2015 to September 2017
Who is funding the study?
1. Ministry of Health (Uganda)
2. The World Bank (USA)

| Scientific title | Efficacy of artemether-lumefantrine and dihydroartemisinin – piperaquine for treatment of uncomplicated malaria in children in Uganda |
| Study objectives | The risk of treatment failure unadjusted by genotyping will be lower in the dihydroartemisinin–piperaquine arm compared to the artemether-lumefantrine arm at each of the sites. |
| Ethics approval(s) | 1. Makerere University School of Public Health Research Higher Degrees Research and Ethics Committee, 10/06/2015, ref: 205 2. Uganda National Council of Science and Technology, 26/06/2015, ref: HS 1356 |
| Health condition(s) or problem(s) studied | Malaria |
| Intervention | Subjects who meet the selection criteria will be randomized to treatment with artemether-lumefantrine (AL) or dihydroartemisinin-piperaquine (DP) and will be followed for 42 days. Repeat evaluations will be performed on days 1, 2, 3, 7, 14, 21, 28, 35 and 42 (and any unscheduled days) and will include assessment for the occurrence of adverse events. |
| Intervention type | Drug |
| Pharmaceutical study type(s) | |
| Phase | Phase IV |
| Drug / device / biological / vaccine name(s) | 1. Dihydroartemisinin–piperaquine 2. Artemether-lumefantrine |
| Primary outcome measure | 1. Risk of parasitological treatment failure (Early Treatment Failure (ETF) 2. Late Parasitological Failure (LPF) 3. Late Clinical Failure (LCF)) All assessed after 42 days of follow-up unadjusted and adjusted by genotyping to distinguish recrudescence from new infections. Risks will be estimated using the Kaplan-Meier product limit formula based on a modified intention-to-treat analysis. |
| Secondary outcome measures | 1. Prevalence of fever (defined as both subjective fever in the previous 24 hours and measured axillary temperature greater than 37.5ºC) on follow-up days 1, 2, and 3 2. Prevalence of parasitemia (proportion of patients with malaria parasites in their blood) on follow-up days 1, 2 and 3 3. Parasite clearance time. Defined as the number (n) and the proportion (%) of patients with a positive parasite count on day 2 and 3 as well as the number (N) of patients evaluated on that day shall be estimated. The parasite clearance rate and initial parasite clearance lag phase duration shall be estimated by modelling the log (parasitemia) time profile using the PCT calculator 4. Change in mean hemoglobin from day 0 to 42 (or day of rescue therapy for patients classified as LCF or LPF), measured from blood samples 5. Prevalence of gametocytemia and gametocyte density in the blood on follow-up days 1, 2, 3, 7, 14, 21, 28, 35 and 42 6. Proportion of patients experiencing any serious adverse event in each treatment group during the 42-day follow-up period (both including and excluding patients classified as ETF or LCF, as recurrent malaria can be confounding) 7. Proportion of patients with adverse events of moderate or greater severity, at least possibly related to the study medications, excluding patients requiring quinine therapy during follow up days. 8. Change in the prevalence of molecular markers in the blood, associated with drug resistance (proportion of patients who fail treatment with K 13 mutants) from day 0 to the day of recurrent parasitemia |
