Background: In high-transmission settings, up to 70% of school-aged children harbour malaria parasites which is mostly asymptomatic, thus, from an epidemiological point of view, they contribute significantly as reservoir to onward malaria transmission to others. In endemic areas, malaria accounts for around 50% of the mortality, 13-50% of all school absenteeism, and causes anaemia in approximately 85 million school-aged children of sub Saharan Africa that also impairs the cognitive development of children. Intermittent preventive treatment (IPT) of pregnant women as well as seasonal malaria chemoprevention in children under the age of five have been implemented in several sub-Saharan countries and have proven to be very effective. However, none of these IPT strategies is targeting school children. A clinical trial is being conducted to expand the IPT by testing effectiveness and safety of two antimalarial drugs Dihydroartemisinin-piperaquine (DP) and Artesunate-amodiaquine (ASAQ) in preventing malaria related morbidity in school aged children (IPTsc) living in high endemic areas. Methods: A randomized, open label, controlled trial will enrol 1602 school children aged 5-15 years, who will receive either DP or ASAQ or control (no drug ), using a "balanced block design" with the "standard of care" arm as reference. The interventional treatments are given every 4 months 3 rounds for the first year. A second non-interventional year will assess possible rebound effects. All study-arms receive bed nets, early diagnosis and care for malaria, and praziquantel and albendazole as mass treatment for helminthiasis. The primary endpoint are change from baseline in mean haemoglobin concentration at months 12 and 20 of follow-up and clinical malaria incidence from month 0 till months 12 and 20 of follow up. Adverse events will be monitored throughout the study. Mixed design methods will be used to assess the acceptability, cost-effectiveness and feasibility of this IPTsc as part of a more comprehensive school children health package. Discussion: The national school health programme (NSHP), Tanzania, combines schistosomiasis and soil transmitted helminthes (STH) control package under national schistosomiasis and STH control programme (NSSCP). Malaria intervention using IPTsc strategy may be integrated in NSHP with the same platform as NSSCP, however, there is limited systematic evidence to assess the operational feasibility of this approach. School aged children are a reachable target population in any endemic malaria setting. The suggested strategy will provide effective protection against malaria, hasten either the elimination process and/or diminish the reservoir and burden.

Other | number of days missed school attendance pre and post intervention period | number of days absent from school pre and post intervention period | at baseline, at month 12 and 20 | |
Other | Change in educational performance | measured by annual change in average score of educational performance pre and post intervention period [to be provided by respective class teachers] | at baseline, at month 12 and 20 | |
Other | change in sustained attention on cognition evaluated using two code transmission tasks using TEA-Ch | sub group of 20 students selected at random in each class will be involved, sustained attention will be evaluated using two code transmission tasks, adapted from the Test of Everyday Attention for Children (TEA-Ch) | evaluated at baseline, at month 12 and 20. | |
Other | change in psychomotor functions tested by 20mShuttle Run Test pre and post intervention | sub group of 20 students selected at random in each class will be involved.Physical fitness will also be assessed using the 20 meter Shuttle Run Test (20mSRT). During this test children run continuously between two lines apart turning when signalled to do so by recorded beeps and a "shuttle" is defined as a run between one line to another. The 20mSRT has 20 levels. | evaluated at baseline, at month 12 and 20. | |
Other | Proportion of participants accepting IPTsc, using and completing dose of given study drugs. | This will be useful on future pragmatic implementation | at baseline, month 4, and 8 | |
Other | Comparison of cost effectiveness of intervention between groups. | Evaluated by assessing the implementation cost (setup, salaries, transport, price scenarios, etc), the study impact as well as possible synergies with other school health intervention programs. In addition,cost per child treated per year, the cost per anaemia case averted and cost per case P. falciparum parasitaemia averted as a result of the intervention, will also be evaluated to determine cost effectiveness of the program. | at month 12. | |
Primary | Change from baseline in mean haemoglobin concentration at months 12 and 20 of follow-up | Will measure change from baseline haemoglobin concentration at month 12 (intervention period) and at month 20 (post intervention period to assess rebound effect) [Note: a trend of change at each visit will also be assessed with respect to malaria seasonality] | at months 0, 12 and 20 | |
