Optimal Chemopreventive Regimens to Prevent Malaria and Improve Birth Outcomes in Uganda

Summary

This trial tests the hypothesis that intermittent preventive treatment in pregnancy (IPTp) with sulfadoxine-pyrimethamine (SP) + dihydroartemisin-piperaquine (DP) will significantly reduce the risk of adverse birth outcomes compared to IPTp with SP alone or DP alone. This double-blinded randomized controlled phase III trial of 2757 HIV uninfected pregnant women enrolled at 12-20 weeks gestation will be randomized in equal proportions to one of three IPTp treatment arms: 1) SP given every 4 weeks, or 2) DP given every 4 weeks, or 3) SP+DP given every 4 weeks. SP or DP placebos will be used to ensure adequate blinding is achieved in the study and follow-up will end 28 days after giving birth.
