Artemether-lumefantrine (Coartem)

Atovaquone-proguanil (Malarone)

Artesunate-mefloquine

Arm Description

Artemether-lumefantrine (Coartem) tablets containing 20 mg artemether and 120 mg lumefantrine twice a day for 3 days, dosage dependent on body weight.

Atovaquone-proguanil (Malarone) tablets containing 250 mg atovaquone and 100 mg proguanil hydrochloride once daily for 3 days, dosage dependent on body weight.

Artesunate-mefloquine tablets containing 50 mg artesunate (Plasmotrim) and 250 mg mefloquine (Mephaquin). Artesunate 4 mg/kg/day (for 3 days) and mefloquine 25 mg/kg/day (days 2 and 3) total dose was given once daily dependent upon body weight.

Outcomes

Primary Outcome Measures

Percentage of Participants With Auditory Abnormalities at Day 7 Assessed by Auditory Brainstem Response (ABR) Wave III Latency Changes on Day 7(a Type of Hearing Test)
To demonstrate the safety of artemether-lumefantrine after 3 days of treatment in patients with acute, uncomplicated falciparum malaria by testing the null hypothesis that the rate of auditory abnormalities is ≥ 15% in the population treated with artemether-lumefantrine as assessed by ABR at Day 7 following initiation of treatment compared with their baseline values. An "auditory nerve abnormality" is here defined as a greater than 0.30 ms change in Wave III latency from baseline to Day 7. Exact Pearson-Clopper two-sided 95% confidence limits were constructed for all three treatment groups.

Secondary Outcome Measures

Auditory Changes Following 3 Days of Treatment at Days 3, 7, 28, and 42 Days as Assessed by Pure Tone Thresholds Assessments (a Type of Hearing Test)
Audiometric measurements such as pure-tone threshold (air conduction tested at 250 to 8000 HZ) day 3, 7, 28 and 42 following initiation of treatment, including changes from baseline. Pure-tone average (PTA) calculated for each ear by averaging the pure-tone threshold values at 500, 1000, 2000 and 3000 HZ.
Relationship Between Changes in Auditory Function and Treatment Groups
ABR Wave III latency (ms) changes from baseline to Day 7 in the three drug exposure groups.
Efficacy of Polymerase Chain Reaction (PCR) Adjusted Malaria Cure Rates of the Three Treatment Regimens at Days 14, 28 and 42
Percentage of patients with clearance of asexual parasitemia (observed by optical microscopy) within 7 days of initiation of trial treatment without recrudescence within 14, 28 and 42 days respectively after initiation of treatment. Patients with recurrent parasitemia and paired PCR results were classified as either a new infection (different paired genotypes) or a recrudescence (matching paired genotypes). Patients without paired PCR results or ambiguous results were classified as treatment failures.
