Summary Objective To assess the efficacy of intermittent preventive treatment (IPT) against malaria in school‐aged children. Methods This was an open randomized controlled trial of seasonal IPT among school children (IPTsc) aged 6–13 years in Kollé, Mali. The study began in September 2007 and completed follow‐up in May 2008. Students were randomized to one of three study arms: Sulfadoxine–pyrimethamine plus artesunate (SP/AS), amodiaquine plus artesunate (AQ/AS) or vitamin C. All students received two full treatment doses, given 2 months apart during the season of high transmission from September to December. Groups were compared with respect to incidence of clinical malaria, asymptomatic parasitemia and haemoglobin concentration. Results A total of 296 students were randomized, and retention in the study was 99.3%. Clinical malaria incidence in the SP/AS and AQ/AS arms was reduced by 66.6% and 46.5%, respectively, vs . vitamin C ( P < 0.001). There were fewer clinic visits for any cause among the children receiving SP/AS or AQ/AS ( P = 0.024). The prevalence of asymptomatic parasitemia was fivefold higher in the vitamin C arm than either SP/AS or AQ/AS at each post‐treatment evaluation ( P < 0.001). At the end of the transmission period, children treated with IPT had lower rates of anaemia (SP/AS, 17.7%; AQ/AS, 16.0%; vitamin C, 29.6%; P = 0.039). Conclusion IPT among school children reduced the rates of clinical malaria, all‐cause acute clinic visits, asymptomatic parasitemia and anaemia among school‐aged children.
