Title: Comparison of Safety, Tolerability and Efficacy of Three Drug Combinations for Intermittent Preventive Treatment in Children Aged 1-5 Years in an Area of Seasonal Malaria Transmission in Upper River Division, The Gambia
Brief Summary: Intermittent preventive treatment (IPT) offers a way of preventing malaria infection without compromising the development of malaria immunity or encouraging drug resistance. The effect of IPT in children in the prevention of malaria has been evaluated in a number of trials in areas of seasonal malaria transmission. Results from these trials have shown that IPTc provided between 40% - 86% protection against clinical malaria. In 2006, a trial that compared two methods of IPTc delivery was carried out in Upper River Division, The Gambia. Preliminary results of the trial have shown that the treatment was very effective as only 4% (45/1133) of the children seen at the end of year cross-sectional survey were parasitaemic. Tolerability was assessed in a subset of 1100 children and the results showed that about 13.5% of children developed mild to moderate vomiting. Malaise was present in about 10% of the study subjects. Severe adverse events were rare. Thus it is important to investigate if other drug regimens might be equally effective in preventing malaria but less likely to cause adverse events. During the 2007 malaria transmission season, 1009 children aged 1-5 years will be individually randomized to receive amodiaquine plus SP, piperaquine plus SP or Artekin TM (dihdroartemisinin plus piperaquine) at monthly intervals on three occasions during the months of September, October, and November. To determine the prevalence of side effects following drug administration participants in each treatment group will be visited at home three and seven days after each round of drug administration and a side effects questionnaire completed. To help establish whether these adverse events are drug related, the same questionnaire will be administered after each treatment round, to 286 age-matched children who are not part of the trial. The primary ends points will be the incidence of adverse events.
