Scientific title


Study hypothesis

We hypothesize that Artemether/Lumefantrine (AL) and Dihydroartemisinin/Piperaquine (DP), each of which is a promising new artemisinin-based combination antimalarial therapy, and Amodiaquine/Sulfadoxine-Pyrimethamine (AQ/SP), an older regimen, will provide outstanding and equivalent efficacy for the treatment of uncomplicated malaria. To test this hypothesis, our aim will be to compare the antimalarial efficacy of these three regimens. The study will be a randomized comparison at three sites in Bobo-Dioulasso. A secondary aim will be to compare the safety and tolerability of the study regimens.

Patient information sheet




This trial compares three therapies for uncomplicated malaria, conducted at three locations in the city of Bobo-Dioulasso, Burkina Faso. The design will closely follow two studies that we conducted in 2004 and 2005 in Burkina Faso (UCSF CHR H2397-25259 and H2397-27158) following guidelines of the World Health Organization (WHO) for assessment of therapeutic efficacy of antimalarial agents in areas of intense transmission, with slight modifications. The target population is residents of three catchment areas within Bobo-Dioulasso, with care at dispensaries at Sarfalao, Colsama and Ouezzin-ville. The available population is residents aged 6 months and older who present to one of the study clinics with symptoms suggestive of malaria and who have a positive screening thick blood smear. Subjects who meet the inclusion criteria and are enrolled in the trial will be randomized to treatment with one of the three study regimens and will be followed for 42 days. The study regimens will be AL (Coartem), DP (Duocotexcin), and AQ/SP, each administered for three days. Repeat evaluations will be performed on days 1, 2, 3, 7, 14, 21,28, 35 and 42 and will include assessment for the occurrence of any serious adverse events. Treatment efficacy outcomes will be assessed using modifications of WHO clinical and parasitological classification criteria.

Patients will be randomized to receive:
1. Artemether-lumefantrine (Novartis, 20 mg artemether/120 mg lumefantrine tablets, 1 [5 - 14 kg], 2 [15 - 24 kg], 3 [25 - 34 kg], or 4 [> 35 kg] tablets twice daily for 3 days) or
2. Amodiaquine (Parke-Davis, 200 mg tablets, 10 mg/kg on days 0 and 1, and 5 mg/kg on day 2) + sulfadoxine-pyrimethamine (Roche, 25 mg/kg of sulfadoxine and 1.25 mg/kg pyrimethamine administered on day 0) or
3. Dihydroartemisinin/piperaquine once daily for 3 days in the morning given in fixed dose tablets (40 mg dihydroartemisinin + 320 mg piperaquine) according to weight-based guidelines consisting of a total dose of 6.4 and 51.2 mg/kg of dihydroartemisinin and piperaquine, respectively.

Primary outcome measures

Primary outcomes will be based on the risk of clinical and parasitological treatment failure after 28 days of follow-up either adjusted or unadjusted

Secondary outcome measures

1. Risk of clinical failure after 14 days of follow-up
2. Risk of rescue therapy after 42 days of follow-up
3. Risk of fever during the first 3 days of follow-up: presence or absence of objective fever (axillary temperature > 37.5°C) or patient report of fever on days 1, 2, 3
4. Risk of parasitemia on follow-up days 2 and 3: proportion of positive vs. negative thick blood smears on day 2 and day 3
5. Change in mean hemoglobin from day 0 to 42 or day of repeat therapy
6. Proportion gametocytemic: presence vs. absence of gametocytes on any follow-up thick blood smear; proportion gametocytemic on days 2, 3, 7, 14, 21, 28, 35 and 42
7. Risk of serious adverse events: proportion of patients experiencing any serious adverse event in each treatment group during the 42-day follow-up period, excluding treatment failures
8. Risk of adverse events of moderate or greater severity, at least possibly related to the study medications, excluding treatment failures

3. Absence of any history of serious side effects to study medications, including allergy to sulfa drugs
4. No evidence of a concomitant febrile illness in addition to malaria
5. Provision of informed consent and ability to participate in 42-day follow-up (patient has easy access to health unit)
6. No history of treatment with any antimalarial (other than chloroquine) in the past 2 weeks.
7. No danger signs or evidence of severe malaria defined as:
7.1 Unarousable coma (if after convulsion, > 30 min)
7.2 Repeated convulsions (> 2 within 24 h)
7.3 Recent convulsions (1-2 within 24 h)
7.4 Altered consciousness (confusion, delirium, psychosis, coma)
7.5 Lethargy
7.6 Unable to drink or breast feed
7.7 Vomiting everything
7.8 Unable to stand/sit due to weakness
7.9 Severe anemia (hemoglobin < 5.0 g/dL)
7.10 Respiratory distress (labored breathing at rest)
7.11 Jaundice (yellow coloring of eyes)

Patients fulfilling these criteria will be assigned a study number and referred to the study nurse for treatment allocation and treatment with the study medications. Patients must also meet the following criterion:
8. Absence of repeated vomiting of study medications on day 0

After treatment with the study medications, patients will be referred to the laboratory. A fingerprick blood sample will be obtained to prepare thick and thin blood smears, and for measurement of hemoglobin. Patients will be excluded from the study on day 1 if the following inclusion criteria are not met.
9. P. falciparum mono-infection
10. Parasite density > 2000/ul and < 200,000/ul
11. Hemoglobin > 5.0 g/dL
