Efficacy and Tolerability of Artesunate Amodiaquine Versus Chloroquine in the Treatment of Uncomplicated Plasmodium Vivax Malaria

Primary Objective: \- To demonstrate the non-inferiority of corrected adequate clinical and parasitological response at Day 28 of Artesunate Amodiaquine (ASAQ) versus chloroquine Secondary Objectives: * To assess the non inferiority on the same way as the main criteria: * at Day 28 before corrected cure rate * at Day 14 and Day 42 before and after corrected cure rate * To compare the two groups of treatment in terms of: * Efficacy: * Proportion of aparasitaemic patients at 24, 48 an 72 hours * Proportion of afebrile patients at 24, 48 and 72 hours * Percentage of gametocyte carriers during follow-up * Evolution of the mean of gametocytes during the 42 days of follow-up * Evolution of haemoglobin value between Day 0 and Day 7, Day 0 and Day 28 * Clinical and biological tolerability: * Proportion of any adverse event * Biological safety: haematology (Red blood cells, Haemoglobin, White Blood Cells, neutrophils, platelets), biochemistry (creatinine, transaminases (alanine amino transferase/ALT), bilirubins) * ECG (electro encephalogram) (Day 0, Day 3,Day 28) only for patients 10 years old and above
