Malaria
Conditions
Brief summary
Few efficient drugs for malaria treatment are available so far. Due to increased exposure of these drugs and due to the high risk of development of drug resistant strains of Plasmodium falciparum, new drug combinations have to be actively investigated. The investigators will test the efficiency, safety and tolerance of combined fosmidomycin and clindamycin treatment in acute uncomplicated malaria in children aged 3-10 years.
Detailed description
Few efficient drugs for malaria treatment are available so far. Due to increased exposure of these drugs and due to the high risk of development of drug resistant strains of Plasmodium falciparum, new drug combinations have to be actively investigated. The goal of this study is to assess a new drug combination, fosmidomycin-clindamycin. The primary objective of the study is to assess and compare the efficacy, safety and tolerance (between sites) of fosmidomycin and clindamycin when co-administered orally over three days in the treatment of acute uncomplicated Plasmodium falciparum malaria in children in Mozambique and Gabon. The secondary objective is to differentiate between recrudescent parasitaemia and reinfection in the event of recurrent parasitaemia developing within the 28-day follow-up period, to determine the population pharmacokinetics of fosmidomycin when co-administered orally with clindamycin and to compare the in vitro sensitivity of isolates of Plasmodium falciparum to fosmidomycin. The trial will include 100 children aged 3-10 years, divided between clinical sites of Gabon and Mozambique.
Interventions
DRUGFosmidomycin and clindamycin
The study drugs will be co-administered under supervision by a study physician or nurse in doses of fosmidomycin 30mg/kg/dose + clindamycin 10mg/kg/dose twice daily for three days (total daily dose fosmidomycin 60mg/kg, clindamycin 20mg/kg).
