66This is an initial efficacy study of a candidate antimalarial in human subjects with uncomplicated malaria caused by the most common and most important parasite in Africa (Plasmodium falciparum). This study will enroll 66 adult Malian males with uncomplicated P. falciparum malaria and randomize them to treatment with 1750 mg of the investigational drug (AQ-13) by mouth over 3 days or the current standard treatment, which is 2 doses of Coartem twice daily for 3 days. The hypothesis underlying this study is that AQ-13 will be similarly effective to Coartem for the treatment of uncomplicated P. falciparum malaria due to both chloroquine-susceptible and chloroquine-resistant parasites.

This is an initial efficacy study (Phase 2 Proof of Concept Study) of a candidate antimalarial in human subjects with uncomplicated malaria caused by the most common and most important parasite in Africa (Plasmodium falciparum). This study will enroll 66 adult Malian males with uncomplicated P. falciparum malaria and randomize them to treatment with 1750 mg of the investigational drug (AQ-13) by mouth over 3 days or the current standard treatment, which is 80 mg of artemether and 480 mg of lumefantrine twice daily for 3 days. The hypothesis underlying this study is that AQ-13 will be similarly effective to Coartem for the treatment of uncomplicated P. falciparum malaria due to both chloroquine-susceptible and chloroquine-resistant parasites.
Adult Malian males 18 years of age or older with uncomplicated P. falciparum malaria who agree to participate and provide their informed consent will be randomized to receive treatment with either AQ-13 or Coartem. Intervention 'AQ-13 Treatment' Participants randomized to the AQ-13 arm will be treated with two (350 mg) capsules on days 1 and 2 and one (350 mg) AQ-13 capsule on day 3 for a total oral dose of 1750 mg of AQ-13 (5 capsules containing 350 mg apiece) over 3 days.
Adult Malian males 18 years of age or older with uncomplicated P. falciparum malaria who agree to participate and provide their informed consent will be randomized to receive treatment with either AQ-13 or Coartem. Intervention 'Coartem Treatment' Participants randomized to the Coartem arm will receive six doses of Coartem tablets over 3 days (each dose containing 80 mg artemether and 480 mg lumefantrine). Those six doses will be given at the time of diagnosis and 8 hours later on day 1, at 24 and 36 hours on day 2 and at 48 and 60 hours on day 3 for total doses of 480 mg artemether and 2880 mg lumefantrine over 3 days.

Adult Malian males 18 years of age or older with uncomplicated P. falciparum malaria who agree to participate and provide their informed consent will be randomized to receive treatment with either AQ-13 or Coartem. Intervention: Active Comparator: Coartem. Participants randomized to the Coartem arm will be treated with 80 mg artemether and 480 mg lumefantrine at the time of diagnosis and 8 hours later on day 1, the same doses (80 mg artemether and 480 mg lumefantrine) twice on day 2 (24 and 36 hours after diagnosis) and twice more on day 3 (48 and 60 hours after diagnosis) for total oral doses of 480 mg artemether and 2880 mg lumefantrine over 3 days.
Inclusion Criteria Adult Malian males ≥ 18 years of age, Uncomplicated malaria with ≥ 2,000 asexual P. falciparum parasites per ul, and Informed consent obtained and signed. Exclusion Criteria Severe or complicated malaria (including temperature ≥ 40o C), ≥ 100,000 asexual parasites per ul of blood, Anemia or other laboratory results (other than malaria) that require treatment (e.g., Hb ≤ 7 gm/dL, K+ ≤ 3.5 millimolar (mM), BP ≥ 140/90), Seizures or impaired consciousness, Recent antimalarial treatment by history (within ≤ 2 weeks), Chronic medications (including inducers of Cytochrome P450 3A4 [CYP3A4] activity such as rifampin and nevirapine), Ventricular or atrial arrhythmias, or second or third degree heart block on the screening ECG or Holter recording, Infection with other plasmodial species on the blood smear (P. ovale, P. ovale, P. vivax).
