Outcomes
Primary outcome [1] 266555 0
% of artesunate-amodiaquine treatment failures (early treatment failure+late clinical failure+late parasitological failure)

Enrolled patients will be assessed for parasitological (using microscopy) and clinical responses during the 28 days follow-up and treatmnt outcomes will be classified according to the latest WHO protocol (http://www.who.int/malaria/publications/atoz/9789241597531/en/index.html).

At 28 day following treatment
Primary outcome [2] 266556 0
% of adverse events (e.g. weakness, headache, nausea, vomiting, abdominal pain, diarrhoea etc) in the artesunate-amodiaquine treated patients. All patients will be asked routinely about previous symptoms and about symptoms that have emerged since the previous follow-up visit. All adverse events will be recorded on the case report form.

Treatment
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential patients will be screened for inclusion/exclusion criteria. Once the patient meets all the enrolment criteria and a parent/guardian consented to participate in the study, the patient will be recruited in to the study. All antimalarial treatments will be given by a study team member under supervision. Thereafter, patients are required to undergo regular clinical reassessment. Blood films for parasite counts will be made on days 2, 3 and 7 and then weekly for the remainder of the follow-up period, i.e. on days 14, 21, and 28.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
This is a one arm prospective study in which all eligible patients are given test drug.

Summary
Brief summary
Title: Efficacy and safety of artesunate + amodiaquine for the treatment of uncomplicated Plasmodium falciparum infection in the new epidemiological context of low malaria transmission in Zanzibar.

Background: Therapeutic efficacy studies will be done in Zanzibar to assess the efficacy and safety of artesunate-amodiaquine for the treatment of uncomplicated falciparum malaria. The study will be conducted in 20 primary health facilities of Zanzibar.

The participants will be febrile people equal to or above 6 months , inclusive. Patients will be treated with artesunate-amodiaquine daily for 3 days. Clinical and parasitological parameters will be monitored over a 28-day follow-up period to evaluate drug efficacy. The results of this study will be used to assist the Ministry of Health and Social Welfare, Tanzania, in assessing the current national treatment guidelines for uncomplicated P. falciparum.
