Design outcomes

Primary

MeasureTime frame
The primary objective of this study is to investigate the pharmacokinetic properties of fixed-dose combination AS/AQ. Blood sampling will be performed at predefined time points in both groups of patients. The evaluation of pharmacokinetics variables will take place over the three-day treatment and the entire follow-up off-treatment.

Secondary

MeasureTime frame
1. Treatment outcomes: the classification of treatment outcomes will be based on an assessment of the parasitological and clinical outcome of antimalarial treatment according to the latest (2005) guidelines of World Health Organisation (WHO). Accordingly, all patients will be classified as having an Early Treatment Failure, a Late Clinical Failure, a Late Parasitological Failure, or an Adequate Clinical and Parasitological Response 2. Safety variables: the occurrence of any adverse event will be documented. All patients will be routinely asked about old symptoms and new symptoms emerging since previous visit during follow-up
