Intervention/exposure

Interventional
Description of intervention(s) / exposure
DHA-PIP (DHA-PIP Trademark, Holley Kin Pharmaceutical Co. Ltd, Guangzhou, China): one tablet of DHA-PIP contains 40mg of dihydroartemisinin (DHA) and 320 mg piperaquine (PIP). It is an oral [by mouth] administration, one dose a day for 3 consecutive days. An adult dose (from 40 kg to 60kg body weight or more than 15 years old) consisted of three doses of 3 tablets over consecutive days (Total dose 9 tablets). The approximate total adult dose was 2-4 mg/kg for DHA and 20mg/kg for PIP.

All doses of medicine will be administered under the supervision of a qualified member of the staff designated by the principal investigator. The study patients will be observed for 30 min after medicine administration for adverse reactions or vomiting. Any patient who vomits during this observation period will be re-treated with the same dose of medicine and observed for an additional 30 min. If the patient vomits again, he or she will be withdrawn and offered rescue therapy. The patients are recommended to stay at the health facilities until they complete the treatment course for malaria infection.

Summary
Brief summary
The general objective of this study is to assess the efficacy and safety of Dihydroartemisinin-Piperaquine in Kvav Health Centre (Siemreap), in Kbal Romeas ( Stung Treng) and in Koh Ngek Health Centre (Mondulkiri) for the treatment of uncomplicated Plasmodium falciparum malaria in Cambodia.
The primary objectives are:
*to measure the clinical and parasitological efficacy of Dihydroartemisinin-Piperaquine for the treatment of uncomplicated P. falciparum in patients aged between 2 and 60 years old, except unmarried 12-18 females, suffering from P. falciparum by determining the proportion with early treatment failure, late clinical failure, late parasitological failure or an adequate clinical and parasitological response as indicators of efficacy;
*to differentiate recrudescence from new infection by polymerase chain reaction (PCR) analysis for P. falciparum malaria;
The secondary objectives are:
*to evaluate the incidence of adverse events; and
*to formulate recommendations and to enable the Ministry of Health to make informed decisions about whether the current national antimalarial treatment guidelines should be updated.
The exploratory objectives are:
*to assess the in vitro susceptibility of P. falciparum solates to dihydroarteminisinin, piperaquine at D0 and Day of recrudescence;
*to determine the polymorphism of molecular markers of Plasmodium falciparum and Kelch gene
