Brief Summary:
Artemisinin-based combination therapies (ACTs) are now the treatment of choice for malaria in non-pregnant individuals living in areas with established chloroquine resistance; they have been shown to be both safe and highly efficacious. There is rapidly increasing experience with artemisinin derivatives in the 2nd and 3rd trimesters of pregnancy, with over 1,000 well documented cases with no reported serious adverse effects to mother or fetus (WHO Malaria Treatment Guidelines, 2006). Many countries in Latin America have abandoned the previous 1st line regimen of Quinine-Clindamycin for treatment of malaria in pregnancy, a complex and poorly tolerated regimen with low adherence, in favor of ACTs, despite limited safety and pharmacokinetic data on the use of these compounds in pregnant women. Lack of pharmacokinetic data may lead to underdosing of pregnant women, with subsequent reduced efficacy and increased potential for development of resistance.
One ACT regimen, Artesunate-Mefloquine, has been developed as a fixed-dose combination (Farmanguinhos Artesunato + Mefloquina), as part of an international collaborative research effort led by Drugs for Neglected Diseases Initiative (DNDi), and manufactured by Farmanguinhos, laboratory of the Brazilian Ministry of Health. Initial clinical trials suggest that it is very well tolerated and efficacious in both pregnant and non-pregnant individuals. The convenient dosing afforded by a fixed drug combination make this a very promising candidate for treatment of pregnant women with malaria. Preliminary pharmacokinetic data from mefloquine monotherapy and prophylaxis suggest that the peak concentration of mefloquine is lowered in pregnant women. Prior to wide-spread adoption of the Artesunate-Mefloquine combination, further studies on safety, efficacy, and dose optimization are imperative. We propose to compare the pharmacokinetics of the fixed combination of mefloquine-artesunate (MA) for treatment of P.falciparum in 28 pregnant women in the second and third trimesters to the pharmacokinetics of this regimen in 28 matched non-pregnant P.falciparum infected women. This will allow us to determine whether the standard adult dose is sufficient for pregnant women.
