663Study treatments:
Artemether-lumefantrine
Artesunate-amodiaquine
Dihydroartemisinin-piperaquine
Location:
Maradi, Niger
Principal Objective:
To measure the clinical and parasitological efficacy of the three artemisinin combination therapies over a period of 42 days from the start of treatment and with polymerase chain reaction assay (PCR) adjustment.
Secondary objectives:
To determine the blood concentration of the non-artemisinin component of the treatment (lumefantrine, desethylamodiaquine or piperaquine) at day 7
To assess the incidence of adverse events during the follow-up period;
To measure speed of parasite clearance
Methods:
In vivo non comparative study as for WHO standardised protocol. The study also measure the concentration of the non-artemisinin component.
Target population:
Children under 5 years of age consulting the integrated health centres of Andoumé and Dix-sept portes in Maradi.
Sample size:
221 patients per study treatment; 663 patients in total.
Treatment allocation:
Random.
Outcomes:
Early treatment failure,
Late clinical failure,
Late parasitological failure,
Adequate clinical and parasitological response.
Analysis:
Cumulative success or failure rate (Kaplan-Meier analysis).
Proportions of early treatment failures, late clinical failures, late parasitological failures, and adequate clinical and parasitological response (called also Per-protocol analysis).

Exclusion Criteria: Presence of general danger signs as defined by the WHO, Presence of signs of severe malaria according to the definitions of WHO, Severe anemia (haemoglobin <5 g/dL), Known history of symptomatic cardiac arrhythmias or with clinically relevant bradycardia, Family history of sudden death or of congenital prolongation of corrected QT interval, Use of antiarrhythmics or neuroleptics, Known history of hypersensitivity to any of the study medications, Severe malnutrition (defined as a weight-height ratio of < -3 z-score according to the 2006 WHO reference (20) and / or a mid-upper arm circumference lower than 115 mm and / or the presence of symmetrical oedema of the feet), Presence of a febrile condition due to a disease other than malaria (i.e. measles, acute lower respiratory tract infection, otitis media, tonsillitis, abscess, severe diarrhoea with dehydration, etc.) History of a full treatment course with one of the three study drugs in the past 28 days. The prior incomplete intake of one of the three study drugs or prior intake of antimalarial drugs not being tested in the study does not exclude a patient from participating in this study. However, information on these previous treatments will be carefully recorded.
