Efficacy of Artemisinin Combination Therapies for the Treatment of Uncomplicated P. Falciparum in Pregnancy in Brazil

Phase 4
Terminated
Conditions
Malaria
Interventions
Registration Number
NCT01082731
Lead Sponsor
Centers for Disease Control and Prevention
Brief Summary

Data on the burden of MIP in low transmission areas, such as Latin America, are very limited; there is even less information on the efficacy of case management of MiP. The treatment recommendations for MiP in Latin American countries have been changing rapidly in recent months; currently, either artemether-lumefantrine (AL) or mefloquine-artesunate (MA) is the first line treatment for P. falciparum (depending on country); however, no data exists on the efficacy of these drugs for the treatment of malaria in pregnancy in Latin America to support their use.

We propose a multi-center 2-arm open-label randomized Phase 4 clinical trial to assess safety and efficacy of the present therapies, AL and MA. We hypothesize that the drugs will both be efficacious for use in pregnant women in Brazil.
