Summary
This will be an open-randomised non-inferiority study to test the hypothesis that the risk of recurrent parasitaemia after 42 days is not worse in the group receiving the Artesunate-Amodiaquine (ASAQ) regimen than in the group receiving the Artemether-Lumefantrine (Coartem®) regimen. Children with uncomplicated malaria meeting the inclusion criteria will be enrolled (after their parent/caretaker has given informed consent), treated on site with the drugs under evaluation and followed-up for a period of 42 days. Drugs will be given under direct supervision, either at the clinic or at home. Follow-up shall consist of a fixed schedule of clinical and laboratory examinations. Based on clinical and laboratory findings, children will be classified as therapeutic failures (early or late) or adequate responders. The proportion of cases experiencing an in vivo therapeutic failure during the follow-up period will provide an estimate of the efficacy of the drug regimens. A Polymerase Chain Reaction (PCR) analysis will be carried out to differentiate true recrudescence due to treatment failure from episodes of re-infection. This proposal is compliant with the latest WHO recommendations for anti-malarial efficacy monitoring in high, medium or low transmission zones11.

Criteria
Inclusion Criteria:

- Age between 6 and 59 months

- Weight ≥ 5 Kg

- Slide-confirmed infection with Plasmodium falciparum only (no mixed infections)

- Asexual parasite density between 2000 and 200000/µl of blood

- Measured axillary temperature ≥ 37.5°C

- Ability to swallow oral medication

- High probability of respecting the follow-up visits (residence within 1 hour walking
distance from the OPD, no upcoming travel plans, etc.)

- Informed consent from a parent or caretaker aged at least 18 years.

Exclusion Criteria:

- • General danger signs according to the WHO definition (Appendix 5.1.1)

- Signs of severe/complicated malaria according to the WHO definition (Appendix
5.1.2)

- Severe anaemia (haemoglobin < 5 g/dL)

- Known history of hypersensitivity to any of the study drugs

- Severe acute malnutrition (as defined by a weight-for-height below -3 Z-score
and/or symmetrical oedemas involving at least the feet)

- Concomitant febrile illness due to causes other than malaria with the potential
to confound study outcome (measles, acute lower tract respiratory infection,
otitis media, tonsillitis, abscesses, severe diarrhoea with dehydration).

- Having received already a full course of the treatment (or one of the treatments)
under study in the previous 28 days (as indicated by the parent/caretaker). Note
that previous incomplete anti-malarial intake of treatments under study, or
previous intake of anti-malarials not under study, are not exclusion criteria,
but details of any such intake should be recorded carefully.

- History of hypersensitivity reactions or contra-indications to any medicines
being tested.
