Study type
Description of intervention(s) / exposure
Study Drugs are dihydroartemisinin-piperaquine (DP) and artesunate-mefloquine (ASMQ). One group was treatedwith DP daily over 3 days, and another group was treated with ASMQ daily over 3 days for uncomplicated Plasmodium falciparum malaria.

DP (oral tablet) with a dose of 4mg/kg for D and 20mg/kg for P daily for 3 days based on the weight group

ASMQ (oral tablet) with AS at a dose of 11-14 mg/kg and with MQ at a dose of 22-28 mg/kg daily based on the weight group
Intervention code [1] 284216 0
Treatment: Drugs
Comparator / control treatment
No control and comparator group. This is a single group trial. In falciparum infected patients, only ASMQ was tested in Pailin and DP was tested in Veal Veng, Preah Vihear and Kratie sites.

Purpose of the study
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
This is a modified single group study where participants received the same drug per site per specie infection. Patients were enrolled in a sequential manner as they come for consultation at the study site and satisfy the inclusion criteria.

Brief summary
This study was a one-arm prospective evaluation of the clinical and parasitological responses to directly observed treatment for uncomplicated falciparum. The objective is to assess the efficacy and safety of dihydroartemisinin-piperaquine (DP) in Pursat, Kratie and Preah Vihear, and artesunate-mefloquine (ASMQ) in Pailin for the treatment of uncomplicated Plasmodium falciparum malaria. The WHO 42-day in vivo protocol was used. Patients with uncomplicated P.f malaria who met the study inclusion criteria were enrolled and treated on site with DP or ASMQ and monitored weekly for 42 days for P.f cases. The follow-up consists of a fixed schedule of check-up visits and corresponding clinical and laboratory examinations. On the basis of the results of these assessments, the patients were classified as having therapeutic failure (early or late) or an adequate response. The proportion of patients experiencing therapeutic failure during the follow-up period were used to estimate the efficacy of the study drug. PCR analysis were used to distinguish between a true recrudescence or reinfection. The results of this study are being used to assist the Ministry of Health of Cambodia in assessing the current national treatment guidelines for uncomplicated Plasmodium falciparum malaria.
