Unanticipated CNS Safety Signal in a Placebo-Controlled, Randomized Trial of Co-Administered Atovaquone-Proguanil and Amodiaquine.

ABSTRACT: Atovaquone-proguanil (ATV-PG) plus amodiaquine (AQ) has been considered as a potential replacement for sulfadoxine-pyrimethamine plus AQ for seasonal malaria chemoprevention in African children. This randomized, double-blind, placebo-controlled, parallel group study assessed the safety, tolerability, and pharmacokinetics (PKs) of ATV-PG plus AQ in healthy adult males and females of Black sub-Saharan African origin. Participants were randomized to four treatment groups: ATV-PG/AQ (n = 8), ATV-PG/placebo (n = 12), AQ/placebo (n = 12), and placebo/placebo (n = 12). Treatments were administered orally once daily for 3 days (days 1-3) at daily doses of ATV-PQ 1000/400 mg and AQ 612 mg. Co-administration of ATV-PG/AQ had no clinically relevant effect on PK parameters for ATV, PG, the PG metaboli
