Summary
This is a two-arm, open label Treatment Study comparing the efficacy, safety, tolerability and pharmacokinetics of a three-day course of Dihydroartemisinin-Piperaquine (DP) with or without single-dose primaquine in patients with uncomplicated Plasmodium falciparum malaria. On the last day of DP therapy, volunteers will be randomized to receive either a single 45 mg dose of primaquine (PQ) or DP treatment only (no primaquine).
