Description of intervention(s) / exposure
This is a surveillance study to monitor the efficacy and safety of the first-line (Arsucam) and second-line (Coartem) antimalarial treatments for uncomplicated falciparum malaria in children Gabon. Eligible patients will be treated with either Arsucam or Coartem (adult tablet or pediatric dispersible tablet). Both drugs will be tested in each of the two sentinel sites; allocation to treatment will be by randomization to avoid the risk of having insufficient patients in one of the two groups at the end of the study period. Patients assigned to Arsucam will be treated with one of the three tablets strengths formulation conatining 25 mg artesunate/67.5 mg amodiaquine; 50 mg artesunate/135 amodiaquine; 100 mg artesunate/270 mg amodiaquine. Coartem tablet containing 20 mg artemether and 120 mg lumefantrine will be used in children over 15 kg, and Coartem dispersible tablets containing 10 mg artemether and 60 mg lumefantrine will be used for children from 5 to 15 kg body weight. The tablets strength and number of tablets to be administered daily will be based on body weight according to standard of care. Coartem daily dose will be administered twice a day and Coarsucam daily dose will be administered once a day. Both treaments will be administered for three consecutive days by study staff. Patients will be seen for clinical and parasitological evaluation, daily for the first 3 days, and then weekly until day 28 or at any time if symptoms re-occurred.
