The Ministry of Health, Division of Malaria Control (DOMC) rolled out the use of artemether-lumefantrine as the first line treatment for uncomplicated malaria in 2006.The development of the ACTs and its derivatives are the most rapidly acting of all the current antimalarial drugs and recognition of their potential role as a component of combination therapy have led to several large trials aimed at assessing different combinations of existing drugs, and to the specific development of new combination drugs.\n\nThis proposal aims to (1) evaluate the efficacy of artemisinin-based anti-malaria combination drugs in different sites across Kenya (2) elucidate the markers of resistance to ACTs through molecular genetics and in this process further strengthen capacity in the proposed study sites as well as improve links between research and control ultimately to influence malaria treatment policy and practice.\n\nFive groups in East Africa will conduct a multi-centre, randomised, two arm trial to assess the efficacy of dihydroartemisin-piperaquine with artemether-lumefantrine as the comparative drug. The network will determine antimalarial drug efficacy using standardised protocols and collate clinical responses and adverse events. Molecular markers to artemisinin resistance will be investigated by molecular sequencing and comparison of parasite profiles in drug failure cases. Recrudescence or re-infections will be differentiated by analysis of the MSP1, MSP2 and GLURP genes and assess transmission dynamics post treatment. Data from these studies will be captured into a database developed by the network. The latter offers several advantages including\n\n* Working towards the standardization of methodologies and common protocols as a way of comparing data across sites\n* Pulling together datasets and conduct a multi-centre analysis\n* Sharing and coordinating quality assurance mechanisms'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD'], 'maximumAge': '10 Years', 'minimumAge': '6 Months', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
