P. falciparum infected patients randomly allocated to this arm will be treated with AS (50mg/tablet) 4 mg/kg body weight once daily for three days followed by DHA-PPQ (40mg of DHA +320mg of PPQ/tablet) once daily for three days.

P. falciparum infected patients randomly allocated to this arm will be treated with the combination DHA-PPQ (40mg of DHA +320mg of PPQ/tablet) once daily for three days.

Drug Resistant Malaria Due to Plasmodium Falciparum

Oral treatment with AS at 4mg/kg/day for 3 days followed by three days of DHA - PPQ in order to insure total parasite clearance. Randomization is done by blocks of ten.

Artesunate (AS) group

Oral treatment with 3-day course of DHA - PPQ. Randomization is done by blocks of ten.

Median parasite clearance time (total hours) in both arms (by light microscopy (LM) and quantitative real time PCR (qPCR)) will be computed using the 12-hourly parasite density measurements from day0 till parasite clearance. Parasite clearance time (in hours) will be computed using the Parasite Clearance Estimator tool available online (http://www.wwarn.org/toolkit/data-management/parasite-clearance-estimator).

This outcome is measured at day 28 and 42 of follow-up. Treatment outcomes such as ACPR, early or late clinical failures are defined following WHO guidelines;

Individual and mean IC50 and IC90 values will be computed for each drug using the IVART tool available online (http://www.wwarn.org/tools-resources/toolkit/analyse/ivart)

asexual and sexual parasite forms will be detected by quantitative qPCR and reverse transcription real time PCR (rtPCR), respectively. This outcome will be measured for each sampling time point.

All parasites at day0, and day3 for patients with delayed clearance, will be genotyped for molecular markers of artemisinin resistance (K13 mutations) following a published protocol.
