Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
To treat the confirmed Plasmodium falciparum malaria patients with artemether–lumefantrine; usual adult oral dose of 4 tabs (each tablet containing 20 mg artemether and 120 mg lumefantrine) twice daily for three days (a target dose 1.3/8 mg /kg twice daily for 3 days) or in dihydroartemisinin-piperaquine combination treatment - orally 3 tablets once (tablet containing 40mg dihydroartemisinin and 320 mg piperaquine phosphate ) per day for 3 days (target dose 2-2.4/16-19.2 mg/kg once a day for 3 days) will be given. Primaquine tablet (containing 7.5 mg ) will be given orally at the dose of 0.75 mg/kg as stat dose for all falciparum infected cases together with first dose of ACT(artemether-lumefantrine or dihydrortemisinin-piperaquine).
For confirmed Plasmodium vivax infected cases, chloroquine tablet (containing 150 mg base) will be given orally at the dose of 10mg/kg for day1 and day2, and 5mg/kg on day3 to have a total dose 25mg base/kg and it will be followed by radical curative treatment with primaquine tablet orally at the dose of 0.25mg base/kg/day for 14 days. If there is G6PD deficiency determined by G6PD RDT, primaquine will not be given.
Case recruitment will start with artemether-lumefantrine to get full sample size and it will be followed by dihydroartemesinin-piperaquine.
To monitor the adherence of ACT and chloroquine, the first dose will be administered at health center under observation of Research Medical Officer, and the following doses will be monitored by malaria volunteer health worker by recollecting the empty blisters daily. Primaquine in vivax infected patients will not be monitored.

Outcomes
Primary outcome [1] 320990 0
Therapeutic efficacy of antimalarials (artemether-lumifantrine) , and dihydroartemisinin-piperaquine in Plasmodium falciparum and chloroquine in Plasmodium vivax malaria.
Treatment outcome will be categorized after 28 day follow up in artemether-lumifantrine, and chloroquine treated group and after 42 day follow up in dihydroartemisinin-piperaquine treated group applying WHO classification as follow;
Early treatment failure
• danger signs or severe malaria on day 1, 2 or 3 in the presence of parasitaemia;
• parasitaemia on day 2 higher than on day 0, irrespective of axillary temperature;
• parasitaemia on day 3 with axillary temperature greater than or equal to 37.5 ºC;
• parasitaemia on day 3 is equal to or more than 25% of count on day 0.
Late treatment failure
Late clinical failure
• danger signs or severe malaria in the presence of parasitaemia on any day between day 4 and day 28 (day 42) in patients who did not previously meet any of the criteria of early treatment failure;
• presence of parasitaemia on any day between day 4 and day 28 with axillary temperature equal to or more than 37.5 ºC in patients who did not previously meet any of the criteria of early treatment failure
Late parasitological failure
• presence of parasitaemia on any day between day 7 and day 28 (day 42) with axillary temperature is less than < 37.5 ºC in patients who did not previously meet any of the criteria of early treatment failure or late clinical failure
Adequate clinical and parasitological response
• absence of parasitaemia on day 28(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
Timepoint [1] 320990 0
At the end of 28 day follow up in artemether-lumifantrine treated group , and Chloroquine treated group, or at the end of 42 day follow up in dihydroartemisinin-piperaquine treated group.
Secondary outcome [1] 373641 0
The proportion of patients with treatment success ( an adequate clinical and parasitological response as indicators of efficacy) .or treatment failure ( early treatment failure, late clinical failure, late parasitological failure) applying WHO definition as follow;
Early treatment failure
• danger signs or severe malaria on day 1, 2 or 3 in the presence of parasitaemia;
• parasitaemia on day 2 higher than on day 0, irrespective of axillary temperature;
• parasitaemia on day 3 with axillary temperature greater than or equal to 37.5 ºC;
• parasitaemia on day 3 equal to or more than 25% of count on day 0.
Late treatment failure
Late clinical failure
• danger signs or severe malaria in the presence of parasitaemia on any day between day 4 and day 28 (day 42) in patients who did not previously meet any of the criteria of early treatment failure;
• presence of parasitaemia on any day between day 4 and day 28 with axillary temperature equal to or more than 37.5 ºC in patients who did not previously meet any of the criteria of early treatment failure
Late parasitological failure
• presence of parasitaemia on any day between day 7 and day 28 (day 42) with axillary temperature less than 37.5 ºC in patients who did not previously meet any of the criteria of early treatment failure or late clinical failure
Adequate clinical and parasitological response
• absence of parasitaemia on day 28(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
Timepoint [1] 373641 0
After 28 day follow up in artemether-lumifantrine treated group , or after 42 day follow up in dihydroartemisinin-piperaquine treated group.
