Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Early treatment failure [Time Frame: within the first 3 days]	Danger signs or severe malaria on day 1, day 2 or day 3 in the presence of parasitemia;Parasitemia on day 2 higher than on day 0, irrespective of axillary temperature;Parasitemia on day 3 with axillary temperature =37.5 ºC;Parasitemia on day 3 =25% of count on day 0.	within the first 3 days
Primary	Late Clinical Failure (LCF)	Danger signs or severe malaria in the presence of parasitemia on any day between day 4 and 42 in patients who did not previously meet any of the criteria of Early Treatment Failure; Presence of parasitemia on any day between 4 and day 42 with axillary temperature =37.5 °C (or history of fever) in patients who did not previously meet any of the criteria of Early Treatment Failure.	42 days
Primary	Late Parasitological Failure (LPF)	Presence of parasitemia on any day between day 7 and day 42 and axillary temperature <37.5 ºC in patients who did not previous meeting any of the criteria of Early Treatment Failure or Late Clinical Failure.	42 days
Primary	Adequate Clinical and Parasitological Response (ACPR)	Absence of parasitemia on day 42 irrespective of axillary temperature, in patients who did not previously meet any of the criteria of Early Treatment Failure, Late Clinical Failure, or Late Parasitological Failure.	42 days
Secondary	The secondary outcome of this study is determining parasite clearance rate based on parasite clearance time.	This study's secondary goal was to calculate the parasite clearance rate based on parasite clearance time. Using hours, days, weeks, and months, parasite clearance time is calculated.	42 days
Secondary	The secondary outcome of this study is determining gametocyte clearance rate based on gametocyte clearance time.	This study's secondary goal was to calculate the gametocyte clearance rate based on gametocyte clearance time. Using hours, days, weeks, and months, parasite clearance time is calculated.	42 days
Secondary	The secondary outcome of this study is determining fever clearance rate based on fever clearance time.	Calculating the fever clearance rate based on fever clearance time was the secondary outcome of this clinical trial. Fever clearance time is calculated using hours, days, weeks, and months. Temperatures less than 37.5 degrees celsius (T 37.5oC) are deemed to be fever-free(fever cleared) while temperatures greater than or equal to 37.5 degrees celsius (T>37.5oC) are classified as having fever (fever not cleared).	42 days
Secondary	The secondary outcome of this study is determining mean hemoglobin change overtime in the 42 days study period.	Calculating the mean hemoglobin change overtime in the 42 study period based on hemoglobin concentration at D0, D14, D28 and D42 was the secondary outcome of this clinical trial. Milligrammes per deciliter are used to measure the concentration of haemoglobin.	42 days
Secondary	The secondary outcome of this study is evaluating the incidence of adverse events in 42 follow-up period.	This study's secondary goal was evaluating the incidence of adverse events in 42 follow-up period.	42 days
