简要总结
Despite all efforts, malaria remains a public health concern, in particular in the Democratic Republic of the Congo (DRC). The National Malaria Control program recommends artemisinin-based combination treatments (ACTs), in particular artesunate-amodiaquine or artemether-lumefrantrine for the treatment of uncomplicated malaria. Previous studies indicated that ACTs are still effective, with efficacy above the required threshold of 90%. It is required to assess regularly the efficacy of antimalarial drugs. I In case of increasing failure rates, alternative options can be decided ontime.
The purpose of this trial is to assess efficacy and safety of artesunate-amodiaquine (ASAQ Winthrop®) and artemether-lumefantrine (Coartem Dispersible®) at day 28 in the treatment of uncomplicated Plasmodium falciparum malaria in six surveillance sites around DRC.
详细描述
This is a phase IV, randomized, open label, 2-arm trial. It will be performed in six malaria sentinel site around the Democratic Republic of the Congo. Children aged 6 to 59 months with confirmed Plasmodium falciparum uncomplicated malaria will be enrolled after informed consent granted by a parent or guardian. They will be randomized to receive either artesunate-amodiaquine or artemether lumefrantrine during 3 days (directly observed treatment) and then followed up until day 28. At each visit, clinical examination will be done and malaria testing as well. Hemoglobin level will be measured on recruitment day and then every two weeks until day 28.
