What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Parasite clearance time
Time Frame: From baseline to the time point when the blood parasite count is zero(up to a maximum of 5 days)
Calculated based on parasite count in blood. In thin film, use actual WBCs/µl, of blood to calculate parasite density by using the following formula: parasites/µl= #parasites× actual WBC/#WBCs counted. In thick film, assume that there are 250 RBCs per HPF, RBC count from 8 HPF equal 2000 RBC, Use actual RBCs/µl blood to calculate parasite density by using the following formula: parasites/µl= # of parasites in 8HPF/2000)× actual RBC.
From baseline to the time point when the blood parasite count is zero(up to a maximum of 5 days)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of participants with adverse events
Time Frame: vital signs: Days 1 through 6; ECG: Days1, 2, 3; Labs: Days 2, 3, 5, study completion
Number of participants with adverse events determined by Vital sign(body temperature, blood pressure and pulse rate): pre dose, 4, 8, 12, 16, 20, 24 hours post dose on Day 1: then 6, 12, 18, 24 hours post dose on each day during domiciles period until at least two consecutive normal temperature readings are obtained, then it will measure daily until Day 6. ECG: 3-4 hours post dose on day1; pre dose, 3-4 hours post dose on Day 2; pre dose, 3-4 hours post dose on Day 3 and study completion. Lab evaluation: Day 2, Day3 and Day5, study completion.
