  Purpose
This will be a randomized, single-blinded, placebo-controlled trial to evaluate the efficacy, safety and tolerability of antimalarial regimens in healthy schoolchildren. The primary objective of the study is to compare the efficacy of different combination antimalarial regimens, including amodiaquine + sulfadoxine-pyrimethamine (AQ+SP), dihydroartemisinin-piperaquine (DP), and placebo, to SP for intermittent preventive treatment (IPT) in schoolchildren, as measured by risk of parasitaemia (unadjusted by genotyping) after 42 days of follow-up. This will assess both the efficacy for treatment of asymptomatic infections and the efficacy for prevention of new infections.

Primary Outcome Measures:
  • Risk of parasitaemia (unadjusted by genotyping) [ Time Frame: after 42 days of follow-up ]

Secondary Outcome Measures:
  • Risk of recrudescence (adjusted by genotyping) in children who were parasitaemic at enrollment [ Time Frame: after 42 days of follow-up ]
  • Risk of new infection (adjusted by genotyping) in all children [ Time Frame: after 42 days of follow-up ]
  • Risk of clinical failure due to recrudescence (adjusted by genotyping) in children who were parasitaemic at enrollment [ Time Frame: after 42 days of follow-up ]
  • Risk of parasitological failure due to recrudescence (adjusted by genotyping) in children who were parasitaemic at enrollment [ Time Frame: after 42 days of follow-up ]
  • Mean haemoglobin [ Time Frame: at day 42 ]
  • Mean change in haemoglobin [ Time Frame: between day 0 to day 42 ]
  • Risk of serious adverse events [ Time Frame: over 42 days of follow-up ]
  • Risk of all adverse events [ Time Frame: after 14 and 42 days of follow-up ]
  • Acceptability of IPT regimens [ Time Frame: on day 7 ]

Detailed Description:
The study will be carried out among children aged ≥ 8 to < 14 years (boys) and ≥ 8 to < 12 years (girls) attending primary schools in Tororo district. Schools will be selected using convenience sampling with the assistance of the district and the education sector. The target population includes children attending primary schools in Uganda. The accessible population includes the children attending the participating primary schools in classes 3-7 in Tororo district. Children who meet the selection criteria for participation in the study will be randomized to treatment with one of the four study regimens and will be followed for 42 days. Repeat evaluations will be performed on days 1, 2, 3, 7, 14, 28, and 42 (and any unscheduled day that a student is ill) and will include assessment for the occurrence of adverse events. Treatment efficacy outcomes will be assessed using revised WHO outcome classification criteria. Acceptability of treatment regimens will be assessed using a questionnaire administered to participating students on day 7. The primary outcome measure is risk of parasitaemia (unadjusted by genotyping) after 42 days of follow-up.
